(Ivanhoe) has asked AMEC Americas Limited (AMEC) to provide an independent mineral resource estimate and Qualified Person's review and Technical Report for the Hugo Dummett (Hugo North deposit) and Southern Oyu deposits of the Oyu Tolgoi project in Mongolia. The work entailed estimating mineral resources in conformance with the CIM Mineral Resource and Mineral Reserve definitions referred to in National Instrument (NI) 43-101, Standards of Disclosure for Mineral Projects. It also involved the preparation of a Technical Report as defined in NI 43-101 and in compliance with Form 43-101F1 (the "Technical Reports"). The work represents a significant change in the size and level of confidence of the Hugo North mineral resources since the last disclosure on this deposit in a Technical Report dated June 2004, and a smaller change in the Southern Oyu deposits since the last disclosure in a Technical Report on these deposits dated September 2004. Dr. Harry Parker, Ch.P.Geol., and Dr. Stephen Juras, P.Geo., directed the mineral resource estimation work and review of the geological data. Dr. Juras most recently visited the project site from 18 to 24 February 2005. Dr. Parker visited the site from 1 to 6 April 2004. Dr. Stephen Juras, P.Geo., an employee of AMEC, who served as the Qualified Person responsible for preparing the earlier Technical Reports, served in the same capacity for this version. The Oyu Tolgoi project consists of copper-gold-molybdenum mineralization in a mid Paleozoic copper-gold porphyry system. It is located in the Aimag (Province) of Omnogov, in the South Gobi region of Mongolia, about 530 km south of the capital city of Ulaanbaatar and 80 km north of the border with China. The Oyu Tolgoi project comprises Mining License 6709A, which covers an area of 8,496 ha. Ivanhoe has been granted the exclusive right to explore within the bounds of its exploration licence. Oyu Tolgoi occurs in an early to mid Paleozoic island arc environment that is part of the Gurvansayhan terrane. The arc terrane is dominated by basaltic volcanics and intercalated volcanogenic sediments, intruded by plutonic-size, hornblende-bearing granitoids of mainly quartz monzodiorite to possibly granitic composition. Carboniferous sedimentary rocks overlie this assemblage. Property geology consists of two major stratigraphic sequences: 1) tuffs, basaltic rocks, and sedimentary strata of probable island arc affinity, assigned to the Upper Devonian Alagbayan Formation; and 2) an overlying succession containing conglomerates, fossiliferous marine siltstones, sandstones, waterlain tuffs, and basaltic to andesitic flows and volcaniclastic rocks, assigned to the Carboniferous Sainshandhudag Formation. The two sequences are separated by a regional unconformity that in the Oyu Tolgoi area is associated with a time gap of 10 Ma to 15 Ma. The southern edge of a large body of hornblende granodiorite outcrops along the northern margin of the exploration block. A wide variety of felsic to mafic dykes are found throughout the exploration block and in drill holes. These include porphyritic quartz monzodiorite dykes that may be genetically related to the copper-gold porphyry systems. Based on satellite imagery and geophysical interpretations, major structures trend N35E and N70E. May 2005 PAGE 1-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA The Southern Oyu deposits include the Southwest, Central, South, and Wedge deposits. These form contiguous zones of mineralization representing multiple mineralizing centres, each with distinct styles of mineralization, alteration, and host rock lithology. The boundaries between the individual deposits coincide with major fault zones. Strong high-sulphidation mineralization and associated advanced argillic alteration, hosted by dacite tuff and quartz monzodiorite, are characteristic of the Central and Wedge deposits, and grade downward into chalcopyrite-gold mineralization with associated biotite-chlorite alteration hosted within basalt. At Southwest the dacite tuff and overlying strata have been removed by erosion, exposing deeper-level chalcopyrite-gold mineralization with associated biotite-chlorite alteration, hosted within basalt. This gold-rich porphyry system is characterized by a southwest-plunging, pipe-like geometry with over 700 m vertical extent. Mineralization at the South deposit is chalcopyrite-bornite dominant with associated biotite-chlorite alteration and is hosted within quartz monzodiorite, basalt, and dacite tuff. The Hugo Dummett deposit contains porphyry-style mineralization associated with quartz monzodiorite intrusions, concealed beneath a deformed sequence of Upper Devonian and Lower carboniferous sedimentary and volcanic rocks. The deposit is highly elongate to the north-northeast and extends over 3.0 km. Although mineralization is continuous over this entire length, it thins marked and decreases in grade where the host strata are displaced by an east-west-striking, north-dipping fault, termed the 110 Fault. This fault defines the boundary between the Hugo South and the Hugo North deposits. The depth to the top of the high-grade zone (3% to 5% Cu) varies from 300 m at Hugo South to about 900 m at Hugo North. The high-grade zone at Hugo North comprises relatively coarse bornite impregnating quartz and disseminated in wall rocks, usually intergrown with subordinate chalcopyrite. Pyrite is rare or absent, except in local areas where the host rocks are advanced argillically altered. In addition, high-grade bornite is associated with minor amounts of tennantite, sphalerite, hessite, clausthalite, and gold. These minerals occur as inclusions or at grain boundaries. Elevated gold grades in the Hugo North deposit occur within the up-dip (western) portion of the intensely-veined high-grade core and within a steeply-dipping lower zone cutting through the western part of the quartz monzodiorite. Quartz monzodiorite in the lower zone exhibits a characteristic pink to buff colour, with a moderate intensity of quartz veining (25% by volume). This zone is characterized by finely disseminated bornite and chalcopyrite, although in hand specimen the chalcopyrite is usually not visible. The sulphides are disseminated throughout the rock in the matrix as well as in quartz veins. The Hugo Dummett deposit has several features unusual to porphyry copper systems, including 1) the anomalously high copper and gold grades, particularly in the northern part of the deposit; 2) an unusually weakly altered pre-mineral sedimentary cover sequence that lies just above the porphyry system; 3) quartz + sulphide vein contents always exceeding 15%, and commonly over 90%, in the high-grade portion of the deposit; and 4) a highly-elongate gently-plunging tabular shape to the high-grade stockwork system. The database used to estimate the mineral resources for the Southern Oyu and Hugo North deposits consists of samples and geological information from 583 drill holes for the Southern Oyu deposits May 2005 PAGE 1-2 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA and 156 drill holes, including daughter holes, for Hugo North. Samples from the drill programs were prepared for analysis at an on-site facility operated by SGS Mongolia LLC (SGS Mongolia). The samples were then shipped under the custody of Ivanhoe to Ulaanbaatar, where they were assayed at a facility operated by SGS Mongolia. Data transfer to the resource database was validated from original certificates through a 5% check of the database. Ivanhoe employs a comprehensive QA/QC program. All sampling and QA/QC work is overseen on behalf of Ivanhoe by Dale A. Sketchley, M.Sc., P.Geo. Each sample batch of 20 samples contains four or five quality control samples consisting of one duplicate split core sample and one uncrushed field blank, which are inserted prior to sample preparation; a reject or pulp preparation duplicate, which is inserted during sample preparation; and one or two standard reference material (SRM) samples (one <2% Cu and one >2% Cu if higher-grade mineralization is present based on visual estimates), which are inserted after sample preparation. A total of 33 different reference materials have been developed for the Oyu Tolgoi deposits and are used to monitor the assaying of six different ore types made up of varying combinations of chalcopyrite, bornite, primary and supergene chalcocite, enargite, covellite, and molybdenite. Ivanhoe strictly monitors the performance of the SRM samples as the assay results arrive at site. If a batch fails based on standard reference material and blank sample tolerance limits from round-robin programs, it is re-assayed until it passes, unless the batch is deemed to represent barren intervals. AMEC reviewed Ivanhoe's QA/QC procedures at site and found them to be strictly adhered to. Results of field blanks show low incidence of contamination and confirm negligible contamination in the assay process. AMEC also evaluated duplicate performance of core, coarse reject, and pulp duplicates was found to be well within the respective accepted ranges. The current Ivanhoe QA/QC program exceeds industry standards and demonstrates that the assay process for the Southern deposits samples is in control and the result suitable for use in mineral resource estimation. Ivanhoe used significant new data from infill drilling at Hugo North and revised structural and intrusive rock interpretations based on ongoing geologic studies at Oyu Tolgoi as a whole to create new 3D shapes of key geologic surfaces, faults, and intrusive units. For Hugo (mainly Hugo North) the changes were major since the last disclosed resource and affected both geologic and structural features. In OTS, the changes were limited to a more consistent interpretation of post-mineral dykes in all deposits and a better definition of geologic contacts in the Wedge zone. AMEC checked the shapes for interpretational consistency in section and plan, and found them to have been properly constructed. The shapes honoured the drill data and appear well constructed. To constrain grade interpolation in each of the zones, AMEC and Ivanhoe created 3D mineralized envelopes or shells. Most were based on initial outlines derived by a method of Probability Assisted Constrained Kriging (PACK). Threshold values were determined by inspection of histograms and probability curves, as well as indicator variography. The shells were based on a copper or gold grade except for the high-grade copper zone in Hugo North, which was defined based on the amount of quartz veining. The OTS gold shells were developed on threshold gold values of 0.7 g/t May 2005 PAGE 1-3 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA for Southwest and 0.5 g/t for Central and South. OTS copper shells (Southwest - Bridge area, Central, South, and Wedge) were based on threshold values of 0.3% Cu. The higher-grade copper zone at Hugo North was defined by a quartz vein percentage threshold (15%). Shell outline selection was done by inspecting contoured probability values. These shapes were then edited on plan and section views to be consistent with the structural and lithologic models and the drill assay data so that the boundaries did not violate data and current geologic understanding of mineralization controls. Traditional grade shells were drawn manually for the lower-grade copper mineralization at Hugo North, as well as Hugo North gold mineralization. The copper shell was made at a grade threshold at 0.6% Cu, whereas the gold shells (Main and West) were drawn at a grade threshold of 0.3 g/t Au. AMEC checked the grade and mineralized shapes for interpretational consistency on section and plan, and found them to have been properly constructed. The shapes honoured the drill data and interpreted geology, and appear well constructed. The estimates were made from 3D block models utilizing commercial mine planning software (MineSight(R)). Industry-accepted methods were used to create interpolation domains based on mineralized geology and grade estimation based on ordinary kriging. The assays were composited into 5 m down-hole composites in the Southern Oyu deposits and 15 m down-hole in Hugo North. The different lengths mirror the proposed mining method in each area (open-pit versus underground block-caving). The compositing honoured the lithology domain zone by breaking the composites on the domain code values. The composites included any post-mineral dyke material intervals that were deemed too small to be part of a post mineral dyke geology model. Any capping limits were applied to the assay data prior to compositing. The Oyu Tolgoi estimation plans, or sets of parameters used for estimating blocks, were designed using a philosophy of restricting the number of samples for local estimation. AMEC has found this to be an effective method of reducing smoothing and of producing estimates that match the Discrete Gaussian change-of-support model and ultimately the actual recovered grade-tonnage distributions. Reasonableness of grade interpolation was reviewed by visual inspection of sections and plans displaying block model grades, drill hole composites, and geology. Good agreement was observed. Global and local bias checks in block models, using nearest-neighbour estimated values versus the ordinary kriged values, found no evidence of bias. Final resource grade values were adjusted to reflect likely occurrences of internal dilution or no-separable dilution from the unmineralized post-mineral dykes. Final resource grade values were adjusted to reflect likely occurrences of internal dilution from the unmineralized post-mineral dykes. The estimated mined resources for Hugo North and Southern Oyu deposits were tabulated and reported using these adjusted or diluted grade values. The mineral resources of the Oyu Tolgoi project were classified using logic consistent with the CIM definitions referred to in National Instrument 43-101. Inspection of the model and drill hole data on plans and sections in the Southwest gold zone area, combined with spatial statistical work and investigation of confidence limits in predicting planned quarterly production, showed good geologic and grade continuity in areas where sample spacing was about 50 m. When taken together with all observed factors, AMEC decided that blocks covered by this data spacing in the Southwest gold zone area may be classified as Measured Mineral Resource. A three-hole rule was used where May 2005 PAGE 1-4 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA blocks containing an estimate resulting from three or more samples from different holes (all within 55 m and at least one within 30 m) were classified as Measured Mineral Resource. The Indicated Mineral Resource category is supported by the present drilling grid over most of the remaining part of the Oyu Tolgoi Southern deposits. The drill spacing is at a nominal 70 m on and between sections. Geologic and grade continuity is demonstrated by inspection of the model and drill hole data in plans and sections over the various zones, combined with spatial statistical work and investigation of confidence limits in predicting planned annual production. Considering these factors, AMEC decided that blocks covered by this data spacing may be classified as Indicated Mineral Resource. A two-hole rule was used where blocks contained an estimate resulting from two or more samples from different holes. For the Southwest deposit the two holes needed to be within 75 m, with at least one hole within 55 m. For the remaining deposits, both holes needed to be within 65 m, with at least one hole within 45 m to be classified as Indicated Mineral Resource. The Indicated Mineral Resource category is supported at Hugo North where the drill spacing is approximately 125 m by 75 m centres. Geologic and grade continuity is demonstrated by inspection of the model and drill hole data in plans and sections over the various zones, combined with spatial statistical work and investigation of confidence limits in predicting planned annual production. Considering these factors, AMEC decided that blocks covered by this data spacing may be classified as Indicated Mineral Resource. To help define the area outlined by this drill spacing, AMEC utilized an indicator variogram method (based on the Quartz Vein domain) where a suitable threshold value was selected by inspection relative to the observed drill hole locations. All interpolated blocks that did not meet the criteria for either Measured or Indicated Mineral Resource were assigned as Inferred Mineral Resource if within they fell within 150 m of a drill hole composite. The mineralization of the Oyu Tolgoi Project as of 3 May 2005 is classified as Measured, Indicated and Inferred mineral resources. The total project mineral resources are shown in Table 1-1, and are reported at copper equivalent cutoff grade of above 0.6%. Hugo South mineral resources are included in the Hugo Dummett total for completeness. Though not re-estimated as part of this work, a revised definition of the separation of Hugo South and Hugo North along the north-dipping 110 fault necessitated a re-tabulation of the existing Hugo South model. The result showed slight variations since the last disclosure in November 2003. The equivalent grade was calculated using assumed metal prices of US$0.80/lb for copper and US$350/oz for gold. For convenience the formula is: CuEq = %Cu + (g/t Au*11.25)/17.64 The contained gold and copper estimates in Table 1-1 have not been adjusted for metallurgical recoveries.

(Ivanhoe) has asked AMEC Americas Limited (AMEC) to provide an independent mineral resource estimate and Qualified Person's review and Technical Report for the Hugo Dummett (Hugo North deposit) and Southern Oyu deposits of the Oyu Tolgoi project in Mongolia. The work entailed estimating mineral resources in conformance with the CIM Mineral Resource and Mineral Reserve definitions referred to in National Instrument (NI) 43-101, Standards of Disclosure for Mineral Projects. It also involved the preparation of a Technical Report as defined in NI 43-101 and in compliance with Form 43-101F1 (the "Technical Reports"). The work represents a significant change in the size and level of confidence of the Hugo North mineral resources since the last disclosure on this deposit in a Technical Report dated June 2004, and a smaller change in the Southern Oyu deposits since the last disclosure in a Technical Report on these deposits dated September 2004. Dr. Stephen Juras, P.Geo., an employee of AMEC, who served as the Qualified Person responsible for preparing the earlier Technical Reports, served in the same capacity for this version. Information and data for the independent resource estimate were obtained from Ivanhoe personnel in Vancouver and from the project site in Mongolia. Pertinent geological data were reviewed in sufficient detail to prepare this document. Dr. Harry Parker, Ch.P.Geol., and Dr. Stephen Juras, P.Geo., directed the mineral resource estimation work and review of the geological data. Dr. Juras most recently visited the project site from 18 to 24 February 2005. Dr. Parker visited the site from 1 to 6 April 2004. 2.1 TERMS OF REFERENCE The Oyu Tolgoi project consists of a series of copper-gold mineralized deposits grouped into the Southern Oyu and Hugo Dummett deposits. The Southern Oyu deposits comprise Southwest, Central, South, and Wedge. Throughout this report, these may be termed SW, CO, SO, and WZ, respectively. Also, Southwest, South, and Central deposits may be called Southwest Oyu, South Oyu, and Central Oyu deposits, respectively. The Hugo Dummett deposits consist of Hugo South and Hugo North. Only Hugo North was part of this review and mineral resource estimate. All units of measure used in this report are in the metric system except contained metal quantities shown in the mineral resource summary tables, which are also expressed in troy ounces and pounds. May 2005 PAGE 1-7 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 3 - DISCLAIMER AMEC's review and resource work relied on work and reports done by Dr. Peter Lewis, P.Geo., of Lewis Geoscience Services Inc. on matters pertaining to structural geology of the Oyu Tolgoi project. AMEC used information from this work under the assumption that it was prepared by a Qualified Person. AMEC's resource work also relied on an ultimate open-pit design shape developed by Minproc Limited of Australia. This work, part of a nearly completed integrated development study on the Oyu Tolgoi project, was used under the assumption that it was prepared by a Qualified Person. May 2005 PAGE 3-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 4 - PROPERTY DESCRIPTION AND LOCATION The Oyu Tolgoi property hosts a series of copper-gold mineralized deposits in a Paleozoic porphyry system. It is located in the Aimag (Province) of Omnogovi in the South Gobi region of Mongolia, about 570 km south of the capital city of Ulaanbaatar and 80 km north of the border with China (Figure 4-1). The Oyu Tolgoi property comprises Mining License 6709A (Figure 4-2), which covers an area of 8,496 ha and is centred at latitude 43(degree)00'45"N, longitude 106(degree)51'15"E. 4.1 MINERAL TENURE Ivanhoe was granted Mining Licenses for the Oyu Tolgoi property and three satellite properties on 23 December 2003, in accordance with the Minerals Law of Mongolia. These licenses give Ivanhoe the right to mine within the bounds of the license area. The licenses are valid for 60 years, with an option for Ivanhoe to extend its license for a further 40 years. These licenses were converted exploration licenses that were originally issued to BHP on 17 February 1997. The exploration license fees were US$1.50/ha in 2002 and 2003 (6th and 7th years of tenure). Thus, Ivanhoe has paid US$12,744 to the Mongolian government each year since acquiring the property. The mining license fees are: - Years 1 to 3.................................$5.00/ha - Years 4 and 5................................$7.50/ha - Years 6 on.................................$10.00/ha. The Oyu Tolgoi property was legally surveyed in August 2002 by Surtech International Ltd. using the internationally recognized survey datum WGS-84. In September 2004, Geomaster Co. Ltd, a licensed Mongolian land survey company, re-surveyed the mining concession's corner points based on the official Mongolian survey datum CS-42 (Krasskovsky) and marked the corners with concrete and steel pylons. Between the northwest and northeast corner points of Oyu Tolgoi mining lease, 6709A, and the adjoining exploration concession 3148X belonging to Entree Gold Inc., Geomaster Co. surveyed the boundary line and marked it with wooden posts on 250 m to 500 m intervals in November 2004.

However, the 2% NSR has now been acquired by Ivanhoe. Terms of this transaction required Ivanhoe to pay BHP Billiton a total of US$37 million in two payments, with the final payment of US$20 million made on 2 February 2004. Royalties potentially payable to the Mongolian government are governed by Article 38 of the Minerals Law of Mongolia, which states: "Royalties shall be equal to 2.5 per cent of the sales value of all products extracted from the mining claim that are sold, shipped for sale, or used. Royalties shall be equal to 7.5 per cent of the sales value of gold extracted from the placer that are sold, shipped for sale, or used." May 2005 PAGE 4-3 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA When the areas were covered by exploration licenses, an environmental plan accompanied the annual work plans submitted to the relevant soum, or district (Khanbogd Soum). The original environmental performance bond was posted in 1998 by BHP and is still retained by the soum for the ongoing work. Further requirements for environmental impact assessment are discussed below. The soum must also be paid for water and road usage. Payments are computed at the end of each calendar year based on the extent of use. Archaeological surveys and excavations have been completed for the project area by the Institute of Archaeology at the Mongolian Academy of Science. Archaeological approvals have been granted for disturbance at the site. 4.3 ENVIRONMENTAL IMPACT ASSESSMENT Project development for Oyu Tolgoi is currently subject to environmental impact assessment (EIA) in accordance with Mongolian environmental laws. The process was initiated with the completion of the "Oyu Tolgoi project Environmental Baseline Study" in October 2002. Ivanhoe submitted this document, along with preliminary project descriptions, to the Ministry for Nature and Environment (MNE) for screening. MNE has reviewed the documentation and prepared guidelines for the completion of a detailed EIA. Sustainability, an Australian consulting firm, is assisting Ivanhoe with the EIA negotiations with the Mongolian Government and is coordinating the preparation of the appropriate documentation. Mongolian law requires a licensed Mongolian consulting firm to prepare the EIA. Accordingly, Ivanhoe engaged Eco Trade Co. Ltd. to complete this work. The final EIA report is expected to be completed and submitted to the government by July 2005. May 2005 PAGE 4-4 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 5 - ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE, AND PHYSIOGRAPHY 5.1 LOCATION The Oyu Tolgoi project is in the Aimag (Province) of Omnogovi, located in the south Gobi Region of Mongolia. The property is approximately 570 km south of the capital city Ulaanbaatar. The elevation of the Oyu Tolgoi property ranges from 1,140 m to 1,215 m above sea level. The topography largely consists of gravel-covered plains with low hills along the northern and western lease borders. Scattered, small rock outcrops and colluvial talus are widespread within the northern, western, and southern parts of the property. 5.2 REGIONAL CENTRES AND INFRASTRUCTURE There are a number of communities in the South Gobi region. The most prominent is Dalanzadgad, population 14,000, which is the centre of the Omnogovi aimag and 220 km northwest of the Oyu Tolgoi property. Facilities at Dalanzadgad include a regional hospital, tertiary technical colleges, domestic airport, and 6 MW capacity coal-fired power station. Ivanhoe envisions that Dalanzadgad may be suitable as a regional centre for recruiting and training. The closest community to the property is Khanbogd, the centre of the Khanbogd soum. Khanbogd has a population of approximately 2,000 and is 45 km to the east. Other communities relatively near to the project include Mandalgovi (population 13,500), which is capital of the Dundgovi aimag and located 310 km north of the project on the road to Ulaanbaatar, Bayan Ovoo (population 1,600), 55 km to the west, and Manlai (population 2,400), 150 km to the north. 5.3 CLIMATE The south Gobi region has a continental, semi-desert climate with cool springs and autumns, hot summers, and cold winters. The average annual precipitation is approximately 80 mm, 90% of which falls in the form of rain with the remainder as snow. Snowfall accumulations rarely exceed 50 mm. Maximum rainfall events of up to 43 mm have been recorded for short-term storm events. In an average year, rain falls on only 25 to 28 days and snow falls on 10 to 15 days. Local records indicate that thunderstorms are likely to occur between 2 and 8 days a year at the project area, with an average total of 29 hours of electrical activity annually. An average storm will have up to 83 lightning flashes a minute. Temperatures range from an extreme maximum of about 36 degrees C to an extreme minimum of about -31 degrees C. The air temperature in wintertime fluctuates between -5 degrees C and -31 degrees C. In the coldest month, January, the average temperature is -12 degrees C. May 2005 PAGE 5-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Wind is usually present at the site. Very high winds are accompanied by sand storms that often severely reduce visibility for several hours at a time. The records obtained from nine months of monitoring at the Oyu Tolgoi project weather station show that the average wind speed in April is 5.5 m/s. However, windstorms with gusts of up to 40 m/s occur for short periods. Winter snowstorms and blizzards with winds up to 40 m/s occur in the Gobi region between 5 and 8 days a year. Spring dust storms are far more frequent, and these can continue through June and July. 5.4 PHYSIOGRAPHY The region is covered by sparse semi-desert vegetation and is used by nomadic herders who tend camels, goats, and sheep. Several ephemeral streams cross the lease area and flow for short periods immediately after rainfall. Water is widely available from shallow wells. The Oyu Tolgoi property is relatively flat with occasional exposed bedrock. This topography will be amenable to the construction of the necessary infrastructure, including tailings storage sites, heap leach pads, waste disposal, and processing plant sites. 5.5 SEISMICITY Knight Piesold completed a full seismic hazard assessment in 2004 and 2005. This assessment incorporates the findings of the seismic assessment completed by the Mongolian Research Centre for Astronomy and Geophysics, Mongolian Academy of Sciences, in March 2005. The seismicity of eastern Mongolia is generally low. The nearest known active sesimotectonic zone to the project site is the Mongolian Altai, approximately 50 km to 100 km to the west. Probabilistic and deterministic methods of analysis of available data concluded that the seismic risk to the Oyu Tolgoi project is low. 5.6 TRANSPORTATION INFRASTRUCTURE Ivanhoe currently accesses the property from Ulaanbaatar either by an unpaved road, via Mandalgovi (a 12-hour drive under good conditions), or by air. Ivanhoe has constructed a 1,600 m long gravel airstrip at the site. The Trans-Mongolian Railway, which crosses the Mongolia-China border approximately 420 km east of the property, traverses the country from southeast to northwest through Ulaanbaatar between Russia and China. The Chinese government has upgraded 226 km highway from Gushaan Suhait to Wuyuan, providing a direct link between the Mongolian border crossing, 80 km south of Oyu Tolgoi, and the Trans-China Railway system (Figure 5-1). Ivanhoe has entered into negotiations with Mongolian and Chinese government authorities to extend the highway the final 80 km to the Oyu Tolgoi project site.

Several possible sources of water lie within 20 km to 60 km of the project site. May 2005 PAGE 5-3 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 6 - HISTORY A minor amount of copper was recovered from malachite and chrysocolla at the South Oyu deposit during the Bronze Age, as indicated by small circular pits and minor copper smelting slag (Tseveendorj and Garamjav, 1999). The Oyu Tolgoi district was explored by a joint Mongolian and Russian regional geochemical survey during the 1980s, when the Central Oyu area was identified as a molybdenum anomaly. Dondog Garamjav (now senior geologist with Ivanhoe Mines Mongolia) first visited Oyu Tolgoi in 1983 and found evidence of alteration and copper mineralization at South Oyu. In September 1996 he brought a team of Magma Copper geologists to the area, who identified a porphyry copper leached cap nearby. Exploration tenements were secured in late 1996. During the 1997 field season, BHP, which had acquired Magma Copper, carried out geological, geochemical, and geophysical surveys and completed a six-hole diamond-drilling program of 1,102 m (Perello, 2001). This program was designed to test the potential for secondary chalcocite mineralization at Central Oyu and for hypogene copper-gold mineralization at South Oyu. Drill hole OTD3 at Central Oyu intersected 10 m of 1.89% Cu from 20 m below surface, and drill hole 4 at South Oyu encountered 70 m of 1.65% Cu and 0.15 g/t Au at a depth of 56 m. A second drilling program of 17 widely spaced, relatively shallow holes (2,800 m total) was completed in 1998. Based on the results of this drilling, BHP in 1999 estimated a preliminary resource of 438 Mt averaging 0.52% Cu and 0.25 ppm Au (Perello, 2001). BHP shut down its exploration in Mongolia in mid-1999 and offered its properties for joint venture. Ivanhoe visited Oyu Tolgoi in May 1999 and made an agreement to acquire 100% interest in the property, subject to a 2% Net Smelter Royalty (NSR). Ivanhoe completed all of its earn-in requirements by June 2002 and became the owner of the property. In November 2003 Ivanhoe acquired the 2% NSR royalty retained by BHP Minerals International Exploration, a subsidiary of BHP. Ivanhoe carried out 8,000 m of reverse circulation (RC) drilling in 2000, mainly at Central Oyu, to explore the chalcocite blanket discovered earlier by BHP. Based on this drilling, Ivanhoe estimated an indicated resource of 31.7 Mt at 0.80% Cu and an additional inferred resource of 11.2 Mt grading 0.78% Cu (Cargill, 2002). In 2001, Ivanhoe continued RC drilling, mostly in the South Oyu area, to test possible oxide resources, and then completed three diamond drill holes to test the deep hypogene copper-gold potential. Hole 150 intersected 508 m of chalcopyrite-rich mineralization grading 0.81% Cu and 1.17 g/t Au. Hole 159 intersected a 49 m thick chalcocite blanket grading 1.17% Cu and 0.21 g/t Au, followed by 252 m of hypogene covellite mineralization grading 0.61% Cu and 0.11 g/t Au. These three holes were sufficiently encouraging for Ivanhoe to mount a major follow-up drill program. In late 2002, drilling in the far northern section of the property intersected 638 m of bornite-chalcopyrite-rich mineralization in hole 270, starting at a depth of 222 m. This hole marked the discovery of the Hugo Dummett deposit. May 2005 PAGE 6-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 7 - GEOLOGICAL SETTING 7.1 REGIONAL GEOLOGY The Oyu Tolgoi camp in southern Mongolia lies within the Paleozoic Gurvansayhan Terrane, which consists of highly-deformed accretionary complexes and oceanic island arc assemblages (Badarch et al., 2002). The Gurvansayhan Terrane is itself a component of the Altaid orogenic collage a continental-scale belt dominated by collisional tectonics related to Late Paleozoic convergence and rotation of Neoproterozoic and pre-0.6 Ga cratonic blocks. In the region surrounding Oyu Tolgoi, the Altaid orogenic collage forms a broad corridor of major strike-slip faults, contractional fault and fold belts, and fault-controlled Mesozoic sedimentary basins. Major structures in this area include the Gobi-Tien Shan sinistral strike-slip fault system, which splits eastward into a number of splays in the Oyu Tolgoi area, and the Gobi Altai Fault system, which forms a complex zone of sedimentary basins overthrust by basement blocks to the north and northwest of Oyu Tolgoi (Figure 7-1). To the east of Oyu Tolgoi, regional structures are dominated by the northeast-striking East Mongolian Fault Zone, which forms the southeastern boundary of the Gurvansayhan Terrane. This regional fault may have formed as a major suture during Late Paleozoic terrane assembly, with Mesozoic reactivation leading to the formation of northeasterly-elongate sedimentary basins along the fault trace. FIGURE 7-1: LOCATION OF OYU TOLGOI, GURVANSAYHAN TERRANE, AND MAJOR CENOZOIC FAULTS IN SOUTHERN MONGOLIA [GEOLOGICAL SETTING MAP] May 2005 PAGE 7-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA The present morphology and structure of southern Mongolia largely reflect the influences of Mesozoic to Cenozoic intra-plate deformation events. The principal recognized deformation episodes include: 1) Late Jurassic to Cretaceous north-south extension, accompanied by the intrusion of granitoid bodies, unroofing of metamorphic core complexes, and formation of extensional and transpressional sedimentary basins; and 2) superimposed northeast-southwest shortening associated with major strike-slip faulting and folding within the Mesozoic basins. 7.2 PROPERTY GEOLOGICAL UNITS 7.2.1 STRATIFIED ROCKS The Oyu Tolgoi area lies within an east-west-trending belt of Devonian-Carboniferous volcanic and sedimentary rocks of continental margin and island arc affinities, constituting the South Mongolia Volcanic Belt. Two major stratigraphic sequences are recognized in the project area (Figure 7-2): 1) tuffs, basaltic rocks, and sedimentary strata of probable island arc affinity, assigned to the Upper Devonian Alagbayan Formation; and 2) an overlying succession containing conglomerates, fossiliferous marine siltstones, sandstones, waterlain tuffs, and basaltic to andesitic flows and volcaniclastic rocks, assigned to the carboniferous Sainshandhudag Formation. The two sequences are separated by a regional unconformity that, in the Oyu Tolgoi area, is associated with a time gap of 10 Ma to 15 Ma. A thin covering of gently-dipping to horizontal Cretaceous stratified clays and clay-rich gravels overlies the Paleozoic sequence, infilling paleochannels, and small fault-controlled basins. DEVONIAN ALAGBAYAN FORMATION The oldest rocks identified at Oyu Tolgoi are correlated with the Upper Devonian Alagbayan Formation. They subcrop in the area around and to the west of the South and Southwest Oyu deposits, and are intersected in drill holes in all of the deposit areas. Four major lithologic divisions are present within the Alagbayan Formation, and each of these divisions comprises two or more mappable subunits. The two lower units are commonly strongly altered and form important ore hosts, while the upper two units, although pre- to syn-mineral in age, lack significant alteration and mineralization. Unit DA1: Basaltic Flows and Volcaniclastic Rocks The stratigraphically lowest rocks identified to date at Oyu Tolgoi consist of mafic volcanic flows and volcanogenic sedimentary rocks, forming a sequence at least several hundred metres in thickness. These rocks are commonly strongly altered and host much of the contained copper in the Southern Oyu and Hugo Dummett deposits. May 2005 PAGE 7-2 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA FIGURE 7-2: STRATIGRAPHIC COLUMN OF PALEOZOIC BEDROCK UNITS IN THE OYU TOLGOI PROJECT AREA [PROJECT AREA] May 2005 PAGE 7-3 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Three main lithotypes are present in the lower sequence. Lowest is a subunit consisting of grey to green finely-laminated volcanogenic siltstone and interbedded fine sandstone. These rocks are overlain by and partially interbedded with dark green, massive porphyritic (augite) basalt, characterized by up to 35% phenocrysts in a fine-grained pilotaxitic matrix of plagioclase and augite. The third principal rock type is monolithologic to slightly polylithic basaltic lapilli tuff to volcaniclastic conglomerate/breccia, occurring above or partially interbedded with the massive augite basalt. Unit DA2: Dacite Tuff / Volcaniclastic Rocks Volcanic fragmental rocks of dacitic composition overlie the basaltic rocks of unit DA1 and form an important ore host in parts of the Hugo South deposit. The dacite sequence can be up to 200 m thick and consists of two major divisions. Volumetrically dominant is buff to dark green, dacite lapilli tuff with common eutaxitic texture and ovoid to globular fragments. This subunit occurs in the lower part of the sequence and is usually overprinted by intense sericite and advanced argillic alteration. It is overlain by or partially interstratified with a thinner unit of typically unsorted, polymictic block tuff to breccia. This coarser subunit is usually less altered than the lapilli tuff and does not contain significant copper mineralization. A zircon U/Pb date of 365+/-4 Ma from the Hugo Dummett deposit constrains the age of the dacite sequence to Upper Devonian (Wainwright et al., 2005). Unit DA3: Clastic Sedimentary Sequence A clastic sedimentary sequence that overlies the dacite marks an important change in stratigraphic style that is recognizable throughout the Oyu Tolgoi project area. This clastic sequence is only weakly altered and measures up to approximately 100 m in thickness. Two main rock types are present. A finer subunit consisting of rhythmically interbedded carbonaceous siltstone and fine brown sandstone forms a lithologically distinctive unit overlying the top of the dacite. This unit is ubiquitous in drill holes in Hugo North and is also discontinuously distributed in the more southerly deposits. A second subunit characterized by polylithic conglomerate, sandstone, and siltstone is abundant in the South Oyu deposits and parts of the Hugo South deposit. The conglomerate typically has a muddy matrix, and is transitional downward to boulder conglomerate and volcanic breccia at the top of the underlying dacite sequence. Cross-cutting relationships with radiometrically-dated units constrain the age of these clastic strata to Upper Devonian. Unit DA4 Basaltic Flows / Fragmental Rocks, Siltstone The uppermost strata of the Alagbayan Formation at Oyu Tolgoi comprise a sequence of basaltic flows and volcaniclastic rocks, overlain by and partly interstratified with thinly-bedded siltstone and massive sandstone. Together with unit DA3, these strata form a weakly-altered to unaltered, pre- to syn-mineralization cover sequence to the Oyu Tolgoi deposits averaging around 600 m thick. May 2005 PAGE 7-4 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Basaltic composition, dark green volcanic breccia with vesicular, fine-grained to coarsely porphyritic basaltic clasts is the dominant lithotype in the upper Alagbayan Formation. These breccias are commonly interstratified with volcanogenic sandstones and conglomerates that appear to be directly derived from the basalts. Middle parts of unit DA4 are dominated by thinly-interbedded red and green siltstone, which contain subordinate basalt layers in their lower levels. Uppermost strata of the unit are massive green to grey sandstone with rare siltstone interbeds. LOWER CARBONIFEROUS SAINSHANDHUDAG FORMATION The Lower Carboniferous Sainshandhudag Formation forms the upper of the two major stratigraphic packages at Oyu Tolgoi. The unit post-dates porphyry mineralization and is separated from the underlying Devonian rocks by a regional unconformity. Radiometric dates and biostratigraphic correlations suggest the unconformity spans a time gap of 10 Ma to 15 Ma, omitting most of the Famennian (Upper Devonian) and Tournaisian (Lower carboniferous) stages. The Sainshandhudag Formation is divided into three major units at Oyu Tolgoi: a lowermost tuffaceous sequence, an intermediate clastic package, and an uppermost volcanic/volcaniclastic sequence. Unit CS1: Andesitic Lapilli Tuff and Volcaniclastic Rocks Lowest strata within the Sainshandhudag Formation in the Oyu Tolgoi area consist of andesitic lapilli tuff with abundant fiamme, and subordinate block tuff to breccia. These rocks are characterized by a crowded feldspar phenocryst-rich matrix and angular lithic clasts, which are invariably fine-grained and non-porphyritic. The andesitic tuff is widely distributed in the Oyu Tolgoi area and measures up to 200 m in thickness. It is absent from the base of the Sainshandhudag Formation in several drill holes along the east side of the Hugo Dummett deposit, where higher units in the Sainshandhudag Formation disconformably overlie Devonian strata. A U/Pb zircon date obtained from the Hugo Dummett deposit area suggests an age of 351 +/- 2 Ma for the andesitic tuff/volcaniclastic unit (Wainwright et al., 2005). Unit CS2: Conglomerate, Sandstone, Tuff, and Coal A clastic sedimentary sequence overlies the lower andesitic package and measures up to 200 m in thickness. The sequence typically shows a progression from a lower conglomerate-sandstone-siltstone dominant unit to an overlying siltstone-waterlain tuff unit. Carbonaceous siltstone and coal beds occur in the lower part of the sequence. Abundant marine and plant fossils constrain an Upper Tournaisian-Lower Visean (Lower Carboniferous) age for the unit. May 2005 PAGE 7-5 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Unit CS3: Basaltic and Andesite Lava and Volcaniclastic Rocks The uppermost division of the Sainshandhudag Formation consists of a thick sequence of andesitic to basaltic flows and volcaniclastic rocks comprising several subunits. These subunits include, in order of superposition, a basal thin volcanic sandstone, a discontinuous porphyritic basaltic andesitic lava sequence, a thick basaltic breccia-to-block tuff unit, and an interstratified- to overlying-porphyritic basalt flow sequence. Together, these units can measure over 800 m in thickness. 7.2.2 INTRUSIVE ROCKS Intrusive rocks are widely distributed through the Oyu Tolgoi area and range from large batholithic intrusions to narrow discontinuous dykes and sills. At least seven classes of intrusive rocks can be defined on the basis of compositional and textural characteristics. Copper-gold porphyry mineralization is related to the oldest recognized intrusive suite, comprising large Devonian quartz monzodiorite intrusions that occur in all of the deposit areas. Many of the older intrusive units found on the property are strongly to intensely altered (e.g., quartz monzodiorite suite), and the compositional classifications used for these units should therefore be considered only as field terms. BASALT / DOLERITE Mafic dykes are the youngest intrusive rocks recognized on the Oyu Tolgoi property and intrude all stratified units. They are typically aphanitic to fine-grained, locally vesicular, and contain variable amounts of plagioclase phenocrysts. In the deposit area, they are limited to dykes from metres to at most a few tens of metres wide, but in the southwest part of the property they may also occur as large, sill-like intrusive masses. This class of intrusions includes a strongly magnetic, north-striking subvertical dolerite dyke that cuts across the Hugo Dummett deposit. RHYOLITE Rhyolite dykes and sills are abundant throughout the property and measure up to a few metres to tens of metres wide, with strike extents of hundreds of metres. Except where emplaced as sills, they typically have steep dips, and strike orientations are variable. Texturally they are aphanitic and aphyric. Intrusive breccias are common along dyke contacts, commonly incorporating both rhyolitic and wall rock fragments within a flow-banded groundmass. U/Pb zircon dates obtained from the rhyolite dykes are 335 +/- 3.1 Ma (Wainwright et al., 2005). HORNBLENDE BIOTITE ANDESITE, DACITE Hornblende biotite andesite and dacite dykes occur in all of the deposit areas, but usually are less volumetrically significant than other intrusive units. Both units are part of a trachyte suite, which may be genetically related to flows and pyroclastic units of the Sainshandhudag Formation. They are typically strongly porphyritic with feldspar, hornblende, and biotite. Quartz phenocrysts are common within the dacite dykes. May 2005 PAGE 7-6 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA BIOTITE GRANODIORITE Late- to post-mineral biotite granodiorite intrusions form a voluminous dyke system along the western side of the Hugo Dummett deposit and the more-restricted dykes and sills elsewhere. The intrusions are compositionally and texturally varied and likely include several intrusive phases. Typically, they contain large plagioclase phenocrysts with lesser small biotite phenocrysts, within a fine-grained to aphanitic brown groundmass. In the Hugo Dummett deposit, the age of the biotite granodiorite is constrained by U/Pb dating of zircon to 362 +/- 4 Ma (Wainwright et al., 2005). QUARTZ MONZODIORITE Porphyry-style mineralization at Oyu Tolgoi is genetically linked to Late Devonian quartz monzodiorite to monzodiorite intrusions, which form the most voluminous intrusions in the deposit area. These intrusions are texturally and compositionally varied, and several distinct phases can be distinguished within the deposits. They are typically phenocryst-crowded, with >40% plagioclase phenocrysts up to 5 mm long, and 10% to 15% biotite and hornblende. Preliminary U/Pb zircon ages of 370.6 Ma and 378 Ma have been obtained from unaltered and altered phases of the quartz monzodiorite in the Southwest Oyu deposit. These dates are at odds with the younger ages obtained from the dacite tuff country rocks and require further analysis. The form and characteristics of the quartz monzodiorite subunits are described in more detail in the following individual deposit descriptions. NORTHWEST GRANITIC COMPLEX The Oyu Tolgoi deposit area is bounded on the northwest by a large, polyphase granitic complex. Intrusive phases recognized in this complex include syenite, granite, quartz monzonite, quartz diorite, and quartz syenite. The temporal relationships between these different compositional phases have not been documented, and the only radiometric date obtained to date is a U/Pb zircon age of 348 Ma (Wainwright et al., 2005), implying that the complex post-dates mineralization at Oyu Tolgoi. The Northwest Granitic Complex is separated from older rocks of the deposit area by the northeast-striking, steeply northwest-dipping North Boundary Fault. The movement history of this fault is uncertain, and it may largely be the result of movement focused along the intrusive contact during post-intrusion deformation. HANBOGD COMPLEX The Early Permian Hanbogd alkaline granite complex is a large, circular intrusion exposed just east of the Oyu Tolgoi property. The complex has a concentric structure defined by abundant pegmatite dykes enriched in rare earth elements and Zr. The Hanbogd Complex has a flat roof, as indicated by numerous basaltic wall rock roof pendants, and may therefore have a "pancake" or lopolithic intrusive form. May 2005 PAGE 7-7 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 7.3 PROPERTY STRUCTURAL GEOLOGY The Oyu Tolgoi project area is underlain by complex networks of faults, folds, and shear zones (Figure 7-3). Most of these structures are poorly exposed on surface and can only be defined through integration of detailed exploration data (primarily drill hole data), property-scale geological mapping, and geophysical data. Ivanhoe has made extensive use of oriented core drilling at Oyu Tolgoi, and the structural data collected has been invaluable in helping determine the subsurface morphology and structural history of the project area. Major structures in the project area strongly influence the distribution of mineralization by both controlling the original position and form of mineralized bodies, and modifying them during post-mineral deformation events. 7.3.1 SOLONGO FAULT The Solongo Fault is an east- to east-northeast-striking, subvertical structure that cuts across the Oyu Tolgoi property just south of the Southwest Oyu and South Oyu deposits. All of the significant mineralization discovered to date on the Oyu Tolgoi property is on the northern block of this fault. The Solongo Fault typically occurs as a strongly tectonized, foliated zone up to several tens of metres wide. Rhyolite dykes commonly intrude the fault zone, and themselves have tectonically brecciated margins. On ground magnetic data, the fault forms a major linear anomaly that can be traced across the entire width of the Oyu Tolgoi property. The Solongo Fault forms a major structural break, and there is a minimum of approximately 1,600 m of south-side-down stratigraphic offset where it juxtaposes mineralized basalt (unit DA1b) in the South Oyu deposit against sediments correlated with the upper Alagbayan Formation (unit DA4) to the south. Depending on movement direction, net slip may be considerably greater. The displacement history of the Solongo Fault is poorly constrained. The fault clearly existed prior to emplacement of rhyolite dykes, which are part of a suite dated at 335 +/- 3 Ma. Rhyolite dykes locally cross the fault with little or no apparent displacement, implying that movement since their emplacement was negligible. May 2005 PAGE 7-8 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA FIGURE 7-3: SIMPLIFIED GEOLOGICAL MAP OF OYU TOLGOI CONCESSION [GEOLOGICAL MAP] Note: Shows distribution of stratigraphic and intrusive units and major structural features of the western two-thirds of the concession May 2005 PAGE 7-9 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 7.3.2 NORTHWEST SHEAR ZONE The Northwest Shear Zone is a wide, ductile shear zone that cuts across the far northwest corner of the Oyu Tolgoi project area (Figure 7-3). This shear zone consists of mylonitic to ultramylonitic rocks in the centre, grading outward over about 200 m to rocks lacking visible ductile strain. Together with the Boundary Fault, the shear zone marks the break between the volcanic and sedimentary strata hosting and surrounding the Oyu Tolgoi deposits (Alagbayan and Sainshandhudag formations), and the carboniferous granitic complex exposed on the northwestern corner of the property. Ubiquitous subhorizontal stretching lineation, asymmetric mesoscopic fabrics (shear bands, asymmetric porphyroclasts), and map-scale deflections of dykes indicate that the Northwest Shear Zone accommodated dominantly dextral strike-slip movement. The magnitude of displacement is not closely constrained, but the geometry of deformed dykes in the shear zone indicates that at least several kilometres of displacement have occurred. Deformed quartz-feldspar porphyry dykes in the shear zone are geochemically identical to the rhyolite intrusions in the deposit area, and have produced an identical U/Pb age of 335 +/- 3 Ma, placing a maximum age on shear zone deformation; no minimum age is constrained. 7.3.3 CENTRAL FAULT The Central Fault is a west-northwest-striking, moderately north-dipping structure that lies between the Hugo South and Central Oyu deposits. It occurs in numerous drill hole intersections in Hugo South, and its surface trace coincides with a strong linear magnetic anomaly. Stratigraphic distribution across the Central Fault shows conflicting stratigraphic relationships at different levels. The fault consists of several splays and may have experienced multiple periods of displacement. The simplest interpretation of geological relationships is that early fault displacement resulted in north-side-down apparent offset, followed by a later apparent reverse displacement of lesser magnitude. Stratigraphic evidence suggests the Central Fault may have been active as a Late Devonian growth fault. However, the fault is clearly visible as a linear magnetic feature cutting the overlying Sainshandhudag Formation, implying that movement continued into the carboniferous or later. 7.3.4 AXIAL FAULT, WEST BAT, EAST BAT FAULTS The alignment of the Southwest Oyu, Central Oyu, and Hugo Dummett deposits, along with the elongate form of the Hugo Dummett deposit itself, strongly implies that an underlying north-northeast-striking fault or fault zone (referred to as the Axial Fault) controlled emplacement of porphyry intrusions and related hydrothermal activity. For example, the tabular, north-northeast-elongate form of the biotite granodiorite dyke complex that follows the west side of the deposit may reflect fault-controlled intrusion. May 2005 PAGE 7-10 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA The Hugo Dummett deposit lies within a north-northeast-trending structural high bounded by the West Bat and East Bat faults. Although the latest movement on these bounding faults displaces post-mineral strata, they may represent the shallow expression of a longer-lived, deposit-controlling fault zone. Offsets of post-mineral stratigraphic contacts measure at least a kilometre (east-side up) for the West Bat Fault, and 200 m to 300 m (west-side-up) for the East Bat Fault. For both of these structures, the true slip direction is uncertain, and if there is a large strike-slip component of movement, total displacement may be significantly greater than stratigraphic offset. 7.3.5 BOUNDARY FAULT SYSTEM Roughly coincident with the northern boundary of the Oyu Tolgoi concession, an east-northeast-striking fault zone juxtaposes the Devonian sequence hosting and overlying the Oyu Tolgoi deposits against the carboniferous granitic complex to the north. Faults within this system include the North Boundary Fault, a splay of the North Boundary Fault, and the Boundary Fault. These faults dip steeply to the north or northwest, and occur as strongly-developed, foliated gouge and breccia zones ranging from decimetres to several tens of metres wide. They juxtapose younger rocks (north block) over older (south block), but true displacement direction and magnitude are poorly constrained. 7.3.6 NORTHEAST-STRIKING SECONDARY FAULTS Magnetic and satellite images show a strong northeast to east-northeast linear structural fabric cutting across parts of the Oyu Tolgoi property. Many of these lineaments can be correlated with faults identified in drill holes (e.g., East Bounding and West Bounding faults at the Southwest Oyu deposit), but others occur in areas where few or no drill holes have been completed, and may mark the positions of undocumented faults. Northeast-striking faults in the Southwest Oyu deposit form a primary control on the distribution of copper and gold mineralization, and the presence of mineralized clasts within the fault zones implies that they were also active following mineralization. Other northeast-striking faults displace stratigraphic contacts in the Lower carboniferous Sainshandhudag Formation near the South Oyu deposit. 7.3.7 FOLDS Variations in bedding attitude recorded in both oriented drill core and surface outcrops define two orientations of folds on the Oyu Tolgoi property: a dominant set of northeast-trending folds, and a less developed set of northwest-trending folds. These folds are well defined in bedded strata of both the Sainshandhudag and Alagbayan formations. They are likely present in stratified rocks throughout the property, but outcrop and drill hole data are insufficient to define them in many areas. Together, the two orientations of folds form a dome-and-basin interference pattern, but it is not possible to determine their relative ages. Both of the dominant fold orientations occur in Lower carboniferous strata, indicating that both folding events post-date mineralization. May 2005 PAGE 7-11 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Sedimentary facing direction indicators in drill holes along the east flank of the Hugo Dummett deposit indicate that parts of the upper Alagbayan Formation are overturned. The overturning is interpreted to be associated with tight to isoclinal folds. These folds are cut by biotite granodiorite dykes, and therefore most were formed within the Late Devonian. 7.4 SOUTHERN OYU DEPOSITS The Southern Oyu deposits include the Southwest Oyu or Southwest, South Oyu or South, Wedge Zone of Wedge, and Central Oyu or Central deposits. These deposits form contiguous zones of mineralization representing multiple mineralizing centres, each with distinct styles of mineralization, alteration, and host rock lithology. The boundaries between the individual deposits coincide with major fault zones (Figure 7-3). Strong, high-sulphidation mineralization and associated advanced argillic alteration, hosted by dacite tuff and quartz monzodiorite, are characteristic of the Central and Wedge deposits. The mineralization grades downward into chalcopyrite-gold mineralization with associated biotite-chlorite alteration hosted within basalt. At Southwest the dacite tuff and overlying strata have been removed by erosion, exposing deeper-level chalcopyrite-gold mineralization with associated biotite-chlorite alteration, hosted within basalt. Mineralization at the South deposit is chalcopyrite-bornite dominant with associated biotite-chlorite alteration, and is hosted within quartz monzodiorite, basalt, and dacite tuff. 7.4.1 SOUTHWEST OYU DEPOSIT HOST ROCKS The Southwest Oyu or Southwest deposit is a Au-rich porphyry system characterized by a southwest-plunging, pipe-like geometry with over a 700 m vertical extent. Over 80% of the deposit is hosted by massive to fragmental porphyritic basalt of the Upper Devonian Alagbayan Formation, with the remainder hosted by intra-mineral, Late Devonian quartz monzodiorite intrusions. The quartz monzodiorite intrusions form irregular plugs and dykes related to several distinct phases. These include 1) early-strongly-altered quartz-veined dykes mainly limited to the high-grade central deposit core (informally referred to as OT-Qmd); 2) superimposed younger fragmental dykes entraining early quartz vein clasts but lacking strong sulphide mineralization (informally referred to as xQmd); and 3) voluminous massive quartz monzodiorite containing weaker mineralization, flanking and underlying the high-grade deposit core. Several phases of post-mineral dykes cut the Southwest deposit. Most of the dykes belong to the rhyolite, hornblende biotite andesite, or biotite granodiorite intrusive phases. They commonly have steep dips, and many are localized along faults. The rhyolite dykes tend to have west to west-northwest strikes in the deposit core and northeast strikes when emplaced along major faults. Hornblende biotite andesite dykes strike east-northeast except where they intrude along the major northeast faults. May 2005 PAGE 7-12 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA STRUCTURAL GEOLOGY Most of the Southwest deposit, and the entire high-grade, gold-rich core of the deposit, lies between two northeast-striking faults, the West Bounding Fault and the East Bounding Fault. Both faults are clearly defined on ground magnetic images, and their positions and orientations are well constrained by numerous drill hole intersections. The bounding faults consist of foliated cataclasite, gouge/breccia, and mylonitic bands in zones ranging from a few metres to a few tens of metres wide. Both faults have subparallel splays locally. Correlation of drill hole intersections constrains an average fault dip of 80(Degree) to 310(Degree) for both faults. The East Bounding Fault juxtaposes younger rocks to the southeast against the Alagbayan Formation rocks (augite basalt) hosting the deposit, while the West Bounding Fault is mainly intraformational within the augite basalt. The West Bounding Fault is commonly intruded by hornblende-biotite andesite dykes, whereas rhyolite dykes are more common along the East Bounding Fault. The cataclasite within the fault zones contains abundant quartz, quartz sulphide, and sulphide (py, cpy, sph, gal) clasts in a comminuted matrix that is locally overprinted by fine-grained pyrite and chalcopyrite. These relationships imply that at least some of the fault movement was contemporaneous with mineralization. Kinematic indicators within the fault zones imply dominantly sub-horizontal, sinistral movement on the bounding faults. Quartz-dominant veins with variable amounts of sulphide (py, cpy, bn), K-feldspar, chlorite, and carbonate are ubiquitous in the Southwest deposit, and there is a general correlation between vein density and copper and gold grade. Most veins have widths of several millimetres to several centimetres, although within the core of the deposit veins up to a metre or more thick occur. Vein contacts can be either planar or variably deformed, and folded and/or faulted veins are common. Veins within the high-grade deposit core display subparallel to sheeted forms with a preferred southwest-dipping orientation. These pass into more irregularly oriented stockwork veins in peripheral mineralized zones, where subvertical north- to northwest-striking orientations are most common. Fault geometry and kinematics, vein orientations, and deposit geometry at Southwest support a structural model invoking deposit formation in a dilational fault transfer zone. This zone is delineated by the West Bounding Fault on the northwest and the East Bounding Fault on the southeast. The preferred vein orientation within the core of the deposit reflects the local stress geometry within this zone of dilation. The Southwest deposit probably formed as a subvertical cylindrical body and attained its present west-southwest plunge during post-mineral regional deformation. This post-mineral rotation is consistent with the easterly stratigraphic dips of both pre- and post-mineral rocks in the deposit area. May 2005 PAGE 7-13 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 7.4.2 SOUTH OYU DEPOSIT HOST ROCKS The South Oyu or South deposit occurs within an east- to northeast-dipping sequence of Alagbayan Formation strata (basalt and dacite tuff units), intruded on the southwest by an irregular quartz monzodiorite body. Much of the basalt sequence contains fragmental textures with juvenile pyroclasts and is texturally similar to the overlying dacite tuff sequence. To the northeast, the altered and mineralized rocks are overlain by mudstones and conglomerates of the upper Alagbayan Formation, which pass up-section into the overlying basalt and sediment sequence and ultimately into rocks of the Sainshandhudag Formation. The deposit area is cut by numerous barren dykes, most of which belong to the post-mineral rhyolite and basalt intrusive suites. These dykes typically have widths of only a few metres, with the exception of a major, east-west rhyolite dyke that cuts through the middle of the South deposit and attains widths of up to a few tens of metres. This wide dyke commonly balloons into larger intrusive masses where it intersects the South and Solongo faults. Although irregular in form, the rhyolite dykes have roughly west to west-northwest strikes and steep dips. In contrast, the basalt dykes have moderate north-easterly dips, subparallel to contacts within the stratified host rocks. STRUCTURAL GEOLOGY The South deposit lies on a fault block bounded on the northwest by the northeast-striking South Fault, and on the south by the east-northeast-striking Solongo Fault (Figure 7-3). The South Fault forms a zone with several strands over a width of up to 90 m, which juxtapose progressively younger strata on the northwest against older strata to the southeast. Drill hole intersections of these faults typically consist of gouge and breccia zones up to several metres wide. To the west, the faults strike into a large quartz monzodiorite intrusion. The faults are difficult to trace through the intrusion and offset of the intrusive contact is minimal, implying that most movement pre-dated emplacement of the quartz monzodiorite. The Solongo Fault truncates the southern edge of the South deposit. It forms a wide, strongly tectonized zone. Stratigraphic offset on the Solongo Fault is at least 1,600 m. No significant mineralization has been identified on the south side of the fault. Copper mineralization in the South deposit is associated with stockworks of thin (usually < 10 cm) quartz+sulphide veins. In surface exploration pits and trenches, veins occur as steep, northwest-striking, strongly sheeted sets. However, veins intersected in drill holes have a stockwork style and lack the strong preferred orientation visible in surface exposures. May 2005 PAGE 7-14 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 7.4.3 WEDGE DEPOSIT HOST ROCKS The Wedge deposit occurs within a northeast-dipping sequence of Upper Devonian Alagbayan Formation strata similar to that hosting the adjacent South deposit. However, in the Wedge deposit, the dacite tuff unit is significantly thicker (up to 180 m) than at South and forms the dominant host to copper mineralization. On the northeast, conformably overlying non-mineralized rocks of the upper Alagbayan Formation and lower Sainshandhudag Formation form the upper limit of mineralization. Mineralized rocks in the Wedge deposit are cut by numerous barren dykes, including biotite granodiorite, hornblende biotite andesite, and rhyolite compositions. Biotite granodiorite and hornblende biotite andesite are more common along the northwest margin of the deposit and typically have northeast strikes, parallel to the East Bounding Fault. These intrusions are also common as sills, typically intruding along the stratigraphic contact between the dacite tuff and the overlying sedimentary strata. Rhyolite dykes are common throughout the deposit. They typically have steeply-dipping contacts but varied strike orientations. STRUCTURAL GEOLOGY The Wedge deposit occupies a rectangular fault block bounded on the west by the northeast-striking East Bounding Fault and on the south by the east-northeast-striking South Fault (Figure 7-3). Within this block, stratigraphic contacts are continuous and relatively planar, showing little evidence of structural disruption. Movement on the East Bounding and South faults has juxtaposed younger strata within the fault block hosting the Wedge deposit against older strata on the adjacent blocks containing the Southwest and South deposits. Stratigraphic contacts are relatively continuous between the Wedge deposit and the Central deposit, implying that displacement on the East Bounding Fault is largely transferred to the Rhyolite Fault (between Southwest and Central), leaving the Wedge and Central as a structurally intact block that has been displaced downward relative to the Southwest and South deposits. Fault disruption is common along the contact between the Alagbayan Formation dacite tuff and the overlying sedimentary strata. However, there is no evidence of significant stratigraphic omission or repetition associated with this faulting, and the movement may be relatively minor. 7.4.4 CENTRAL OYU DEPOSIT HOST ROCKS The Central Oyu or Central deposit is hosted within a swarm of feldspar-phyric quartz monzodiorite intrusions, emplaced into porphyritic augite basalt and overlying dacite tuff of the Alagbayan May 2005 PAGE 7-15 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Formation. The dacite tuff is in turn overlain by unmineralized sedimentary and mafic volcanic rocks of the upper Alagbayan Formation, which currently dip moderately to the east. Several phases of intra-mineral and late-mineral quartz monzodiorite intrusions have been distinguished in the Central deposit based on textural variations and intensity of mineralization and alteration. Most have dyke forms, emanating from a larger intrusive mass to the north and west of the deposit area. The quartz monzodiorite dykes terminate within the base of the sedimentary units of the upper Alagbayan Formation. Basalt flows and dacite tuffs of the Alagbayan Formation are preserved as a series of isolated, irregular, moderately north- to northeast-dipping bodies within the quartz monzodiorite dyke swarm. These volcanic windows are up to 200 m thick and extend several hundred metres down dip to the limit of drilling. The contact between the dacite and the overlying sedimentary sequence is commonly faulted and forms the upper limit to mineralization, as elsewhere in the Oyu Tolgoi district. Post-mineral dykes are common in the Central deposit and comprise rhyolite, biotite granodiorite, hornblende biotite andesite, and dacite dykes. The rhyolite dykes are most abundant, with the majority occurring as west- and west-northwest-striking bodies in the southern half and on the periphery of the deposit. Biotite-granodiorite dykes occur along the deposit's eastern margin and tend to strike north to north-northeast. East-northeast striking hornblende biotite andesite dykes occur mainly along the north-eastern margin of the deposit. STRUCTURAL GEOLOGY Drill holes through the Central deposit show little evidence of significant post-mineral faulting, and the mineralogical zoning, grade distribution, and continuity of contacts are consistent with the deposit being contained in a structurally intact block. Most contacts in the deposit are intrusive or stratigraphic, although minor faulting occurs locally. Post-mineral faults form minor zones of breccia and cataclasite in some drill holes, but it is not possible to correlate these intersections between drill holes to define continuous fault surfaces. Pre- or syn-mineral faults, if present, are largely obscured by intrusive and hydrothermal overprinting. The Central deposit area is overlain to the east by non-mineralized conglomerate, mudstone, and siltstone of the upper Alagbayan Formation. Wide zones of breccia and foliated breccia occur either along the basal contact of or within the lower portion of these sedimentary strata. The displacement history of these zones is uncertain, and they may be related to minor post-mineralization movement between the two rheologically contrasting rock packages. Along its southern margin, the Central deposit is juxtaposed against the Southwest deposit area by an east-west-striking fault that is now occupied by a rhyolite dyke (the Rhyolite Fault). The ignimbrite and overlying sedimentary units have been uplifted and eroded from the block south of this fault. May 2005 PAGE 7-16 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Mineralized veins within the Central deposit show a range in orientations, the most common including southwest-, west-, and northwest-dipping attitudes. Vein orientations are similar to those documented in the Southwest deposit, although the degree of preferred orientation in the deposit core is weaker at Central. Similar preferred vein orientations at Central and Southwest suggest that the two deposits were formed in a similar structural regime. However, the Central deposit lacks the strong bounding fault control that is fundamental to the form and geometry of the Southwest deposit. This lack of bounding fault control may account for the more-irregular form of the mineralized body at Central. Post-mineral tilting of the Central deposit is implied by bedding dips in the enclosing and overlying stratigraphic sequence. Rotating the structural data for the Central deposit sufficiently to restore bedding to horizontal indicates a strong preference for subvertical veins within the deposit at the time of formation. 7.5 HUGO DUMMETT DEPOSITS The Hugo Dummett Deposits contain porphyry-style mineralization associated with quartz monzodiorite intrusions, concealed beneath a deformed sequence of Upper Devonian and Lower carboniferous sedimentary and volcanic rocks. The deposits are highly elongate to the north-northeast and extend over 3 km (Figure 7-3). Although mineralization is continuous over this entire length, it thins markedly and decreases in grade where the host strata are displaced by an east-west striking, north-dipping fault, termed the 110 Fault. This fault defines the boundary between the Hugo South and the Hugo North deposits. The depth to the top of the high-grade (>2.5% Cu) zone varies from 300 m at Hugo South to about 900 m at Hugo North. 7.5.1 HUGO SOUTH DEPOSIT HOST ROCKS The Hugo South deposit is hosted by an easterly-dipping sequence of volcanic strata correlated with the lower part of the Devonian Alagbayan Formation and quartz monzodiorite intrusive rocks. Stratigraphically lowest rocks in the sequence consist of porphyritic basalt flows and minor volcaniclastic strata. These rocks are overlain by dacite tuffs and breccias forming a sequence approximately 100 m to 200 m thick. Weakly-altered to unaltered sedimentary and volcanic rocks of the upper Alagbayan Formation and Sainshandhudag Formation overlie the mineralized sequence along the eastern flank of the Hugo South deposit. The thickness of the non-mineralized Alagbayan Formation sequence commonly exceeds 600 m, although structural thickening may occur within the sequence. The Sainshandhudag Formation strata unconformably overlie, and are locally faulted against, the Alagbayan Formation. Several phases of intrusive rocks occur in the Hugo South deposit. The oldest recognized intrusions are quartz monzodiorite bodies, which underlie the entire deposit area and contain low copper May 2005 PAGE 7-17 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA grades. Quartz monzodiorite contacts are irregular, but overall show a preferred easterly dip, subparallel to contacts in the enclosing stratified rocks. The quartz monzodiorite is broadly contemporaneous with alteration and mineralization, and two varieties are distinguished on the basis of alteration characteristics and position within the deposit: 1) an intensely quartz veined phase that occurs along the upper margin of the main intrusive body or as a separate east-dipping tabular body in the overlying strata; and 2) a lower-grade, more weakly veined variety, which makes up the large intrusive body forming the lower part of and underlying the entire deposit. Late- to post-mineral biotite granodiorite intrusions form a north-northeast-striking dyke complex cutting across the western edge of the deposit. Based on correlations between drill hole intersections and measurements of individual contacts using oriented drill core, dyke contacts appear to have a moderate to steeply west-dipping preferred orientation. Younger intrusions include rhyolitic, hornblende biotite andesite, dacite, and basalt/dolerite compositional varieties. These intrusions usually occur as dykes with subvertical orientations, or less commonly as easterly-dipping sills emplaced along stratigraphic contacts. They are non-mineralized and not volumetrically significant except locally in the deposit. STRUCTURAL GEOLOGY The Hugo South deposit occurs within a north-northeasterly elongate block bounded on the north and south by moderately north-dipping faults, and on the east and west by steep, north-northeast-striking faults. Strata within the block form a homoclinal sequence dipping moderately to the east-southeast. Deformation of the Hugo South deposit is dominated by brittle faulting (Figure 7-4). Major faults cutting the deposit can be grouped on the basis of orientation into four sets: 1) east-west striking, moderately north-dipping faults (110, Central faults); 2) steep north-northeast-striking faults (East and West Bat, East Hugo, and Axial faults); 3) north-northeast-striking faults that dip moderately east, subparallel to lithologic contacts (Contact, Lower faults); and 4) east-west-striking, subvertical faults (East-West Fault). 110 Fault The 110 Fault defines the division between the Hugo North and Hugo South deposits, although mineralization is continuous across the fault. The fault strikes east-west and dips northerly at approximately 45 degrees to 55 degrees. In drill hole intersections, the 110 Fault consists of zones of non-cohesive gouge and breccia up to several metres thick. Tectonic fragments within the fault zone are derived from adjacent wall rocks and include mineralized quartz veins within strongly foliated clay gouge.

The stratigraphic offset of the base of the upper member of the Alagbayan Formation varies between approximately 100 m and 200 m. Depending on the net slip direction, the true offset may be greater. The fault is truncated up-dip by the East-West Fault, and the intersection between the two fault surfaces is subhorizontal. Because it is truncated by the East-West Fault, the 110 Fault does not have a surface trace in the Hugo Dummett deposit area. Stratigraphic evidence suggests that earliest movement on the 110 Fault had a large north-side-down component and may have been syn-depositional with respect to the strata immediately overlying the ignimbrite unit. In particular, in several areas coarse volcanic breccias (block and ash tuff unit) are thicker in drill holes immediately north of the fault than on the southern fault block. In addition, the upper basalt + sediment portion of the Alagbayan Formation is up to 200 m thicker on the northern fault block than to the south. However, the variation in thickness could be associated with varying depths of erosion at the disconformity marking the top of the unit. Additional evidence for early movement on the 110 Fault is the lack of offset of the biotite granodiorite dyke contact May 2005 PAGE 7-19 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA where the two intersect, implying that most of the stratigraphic displacement pre-dates dyke emplacement. Kinematic indicators in the foliated gouge indicate oblique sinistral + reverse movement on the 110 Fault, contrary to the apparent stratigraphic displacement. These fabrics likely record a late period of movement that is of lesser apparent magnitude than earlier displacements. Cataclasite developed during this stage of movement contains tectonic fragments of veins with copper sulphides, indicating post-mineral timing. However, the late fault movement does not significantly displace mineralization. Central Fault The Central Fault is a shallowly to moderately north-dipping structure that lies beneath the southern portion of the Hugo Dummett deposit. It projects to surface between the Hugo South and Central deposits. Drill hole intersections indicate a strike of approximately 90 degrees to 100 degrees, and its surface trace coincides with a strong linear magnetic anomaly. At shallow levels, stratigraphic contacts are offset across the Central Fault with apparent normal displacement. At deeper levels (OTD401 series drill holes), the opposite stratigraphic relationships occur: dacite tuff of the Alagbayan Formation is faulted over sedimentary strata correlated with the upper Alagbayan Formation. In drill core, the Central Fault consists of a zone of fault breccia and gouge that can be up to several metres thick. Contradictory stratigraphic relationships (stratigraphic repetition at deeper levels, stratigraphic omission at shallow levels) imply that the Central Fault may have experienced multiple periods of displacement, similar to the history proposed for the 110 Fault. The simplest interpretation is that early displacement resulted in north-side-down apparent offset, followed by a later period of reverse displacement during a period of roughly north-south contractional deformation. The magnitude of reverse displacement was insufficient to restore the entire apparent normal offset. At depth, the reverse sense reactivation may have been localized along a splay in the hangingwall of the principal fault surface, resulting in local stratigraphic repetition. East-West Fault The East-West Fault cuts across and displaces the northern end of the Hugo South deposit. Drill hole intersections constrain the fault orientation to subvertical with a strike of approximately 080 degrees to 090 degrees. It forms an abrupt boundary to alteration and mineralization in several sections. Biotite granodiorite dyke contacts -- the Contact Fault, East Hugo Fault, 110 Fault, and East Bat Fault -- are all cut by the East-West. In drill hole intersections, the East-West Fault occurs as a zone of clay-rich breccia and locally foliated gouge up to several metres in width, similar in character to the Central and 110 faults. Narrow basaltic dykes commonly occur within the fault zone. May 2005 PAGE 7-20 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Offsets of a late basaltic dyke, stratigraphic contacts, and the axis of the Hugo South deposit constrain an oblique dextral + north-side-down net slip of roughly 150 m to 200 m on the fault, along a gently eastward-plunging slip vector. Deposit-Parallel Faults Moderately east-dipping (deposit-parallel) faults that occur within and immediately adjacent to the Hugo Dummett deposit include the Contact Fault and the Lower Fault. The Contact Fault is a bedding-parallel detachment zone that normally occurs at the transition between the dacite tuff unit (middle Alagbayan Formation) and the overlying sediment/basalt sequence. The intensity of fabric development along this fault is highly variable: in some drill holes it occurs as a wide zone of anastamosing foliation and brecciation in carbonaceous mudstones within the base of the upper sequence; elsewhere there is little tectonic disruption along the contact. The Contact Fault is often intruded by dykes or sills of basaltic, andesitic, or rhyolitic composition. The Contact Fault marks the upper limit of strong alteration in most of the Hugo Dummett deposit. Bedding above and below the faulted contact is concordant. Other than the variable thickness of lithologic marker unit near the contact (e.g., uppermost block and ash tuff in the middle Alagbayan Formation), there is no indication that significant structural omission or repetition has occurred at the Contact Fault. In the western part of the Hugo Dummett deposit, the biotite granodiorite dyke crosses the Contact Fault at a high angle. The fault continues as a narrow zone of breccia and clay gouge in the biotite granodiorite, but is difficult to identify in many drill holes. Although there is likely some displacement of the intrusive contact, the magnitude is too small to be mappable with the present drill hole spacing. The Lower Fault occurs as an intensely brecciated, clay gouge-rich zone within the middle or lower portion of the mineralized body, typically 200 m to 400 m below the Contact Fault. Similar to the Contact Fault, the Lower Fault can be traced westward through at least part of the biotite granodiorite dyke as a narrow zone of breccia and gouge. Latest movement on the deposit-parallel faults post-dates both mineralization in the Hugo Dummett deposit and intrusion of the biotite granodiorite dykes. It is difficult to clearly demonstrate geological offsets on the deposit-parallel faults. The lack of apparent offset may in part reflect the absence of clear stratigraphic markers at the levels at which the faults occur, as well as the fault orientation being close to that of both stratigraphic and alteration contacts. However, in the Hugo North deposit, the Lower Fault appears to displace the Hugo North gold zone and biotite granodiorite dykes by up to 400 m. The contact-parallel nature of the Contact and Lower faults suggests that they may have formed as gently-dipping thrusts during regional contractional deformation. These faults were localized along contacts between units with differing competencies, or along relatively weak layers within the stratigraphic sequence. May 2005 PAGE 7-21 [AMEC LOGO [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Axial Fault The linear mineralized trend defined by the Central, Southwest, and Hugo Dummett deposits, which now measures over 6.5 km, likely reflects the presence of a deep, north-northeast-striking crustal fault or fault zone controlling magma emplacement and mineralization. This inferred structure probably also controlled emplacement of the north-northeast-striking late-mineral biotite granodiorite dyke. Although the controlling structure is largely conceptual and direct evidence for it would have been overprinted in many areas by the biotite granodiorite dyke, it is referred to for convenience as the Axial Fault. Apparent offsets of stratigraphic contacts across the main biotite granodiorite dyke provide supporting evidence for the existence of the Axial Fault (Figure 7-4). Depending on how contacts are projected through areas with low drill hole density, the basal contact of the upper member of the Alagbayan Formation shows an apparent stratigraphic displacement of approximately 200 m to 300 m across the biotite granodiorite dyke. Because the slip direction is unknown, this represents the minimum amount of movement on the fault. There is no clear evidence for post-dyke movement on the Axial Fault. This restricts the timing of movement to the narrow time interval between deposition of upper Alagbayan Formation and intrusion of the biotite granodiorite. West Bat Fault The West Bat Fault is a north-northeast-striking, subvertical structure that extends along the west side of the Hugo Dummett deposit. It cuts the northwestern edge of the Hugo North deposit, but is well west of the main part of the Hugo South deposit. The structural character of the fault in drill hole intersections varies with both depth and stratigraphic level. In deeper intersections, where the fault juxtaposes massive volcanic conglomerates (upper Sainshandhudag Formation) against quartz monzodiorite, biotite granodiorite, or lower Alagbayan Formation, it occurs as a weakly to moderately foliated gouge and breccia zone up to a few metres wide. At shallower levels, the fault forms a much broader tectonized zone and commonly splits into several subparallel splays. The West Bat Fault juxtaposes significantly lower stratigraphic levels to the east against higher stratigraphic levels to the west. If the base of the upper Sainshandhudag Formation is used as a marker, stratigraphic offset, and therefore the minimum net slip, is over 1,500 m. Determination of true net slip amount and direction on the West Bat Fault is complicated by the probable multiple periods of movement on the fault, and available data do not uniquely constrain the fault movement history. East Bat Fault The East Bat Fault is a north-northeast-striking, subvertical structure occurring along the east side of the Hugo Dummett deposit. Although contact positions adjacent to the fault imply a minimum of a few hundred metres' displacement, the fault expression in drill core can be subtle, often amounting May 2005 PAGE 7-22 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA to only decimetres of foliated gouge or cataclasite. The East Bat Fault occurs well east of the mineralization defined within the Hugo South deposit. Stratigraphic contacts within the Sainshandhudag Formation show around 200 m to 300 m of east-side-down stratigraphic offset across the East Bat Fault. There is no kinematic information available for the fault, so the true slip direction and amount are uncertain. Much, if not all, movement would have been post-mineral: the fault cuts carboniferous strata of the Sainshandhudag Formation, but is itself cut by the East-West Fault. East Hugo Fault The East Hugo Fault occurs as a north- to north-northwest-striking, steeply east-dipping zone of strong to intense brecciation and clay gouge occurring along the east limb of the Hugo South and Hugo North deposits. At Hugo South it cuts across stratigraphic contacts at moderate angles and forms a sharp break in alteration intensity and copper grade. It displaces mineralization, and there is no evidence in grade distribution or alteration to suggest that the fault was present at the time of mineralization. Drill hole data suggest that the East Hugo Fault cuts the 110 Fault but is displaced dextrally by the East-West Fault. Sections where fault and contact geometry are best constrained show apparent east-side-down displacement of the Alagbayan Formation contacts ranging from about 200 m to as much as 400 m. The true slip direction, and thus the amount of net slip, is not constrained. Folding History Bedding measurements obtained from oriented drill core, mainly from bedded intervals within the upper Alagbayan Formation, define two orientations of folds in the Hugo South deposit area: a dominant set of north-northeast-trending folds, and a subordinate set of northwest-trending folds. Both of the dominant fold orientations also occur in carboniferous post-mineral strata, indicating that both events post-date mineralization and may have modified the form of the deposit. Within the upper Alagbayan Formation, north-northeast-trending folds have wavelengths and amplitudes on the scale of metres to tens of metres. The far greater abundance of east-dipping bedding measurements implies that the fold geometry is strongly asymmetric, characterized by west-verging folds. In contrast, northwest-trending folds have wavelengths of hundreds of metres and open, symmetric forms. Together, the two fold sets define an elongate dome and basin interference pattern. Because the axial surfaces and fold axes of the two sets are at a high angle to one another, and no penetrative cleavage fabrics formed during either event, it is not possible to determine their relative ages in the deposit area. Reversals in sedimentary facing direction occur locally in the upper part of the Alagbayan Formation along the east flank of the Hugo South deposit. These reversals suggest the presence of tight to isoclinal folds affecting at least the Alagbayan Formation. These same overturned folds occur in the Hugo North deposit, where they are cut by the Late Devonian biotite granodiorite dyke. These May 2005 PAGE 7-23 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA cross-cutting relationships effectively bracket the timing of folding to Late Devonian, roughly contemporaneous or close in age to mineralization. 7.5.2 HUGO NORTH DEPOSIT HOST ROCKS The Hugo North deposit occurs within a geological setting similar to that at Hugo South. Host rocks are an easterly-dipping sequence of volcanic strata correlated with the lower part of the Devonian Alagbayan Formation and quartz monzodiorite intrusive rocks. Stratigraphically lowest rocks in the sequence consist of basalt flows and minor volcaniclastic strata overlain by a dacite tuff and breccia sequence. The dacite sequence includes a lower lapilli tuff unit, with overlying coarser tuffs and breccias. Weakly-altered to unaltered sedimentary and volcanic rocks of the upper Alagbayan Formation and Sainshandhudag Formation overlie the mineralized sequence along the eastern flank of the deposit. Farther to the east and up-section, Sainshandhudag Formation rocks unconformably overlie and are locally faulted against the Alagbayan Formation. Intrusive rocks at Hugo North are dominated by quartz monzodiorite bodies that underlie the entire deposit area and host a significant portion of the copper and gold mineralization. Quartz monzodiorite contacts are irregular, but overall show a preferred easterly dip, subparallel to stratification in the enclosing rocks. The quartz monzodiorite is contemporaneous with alteration and mineralization, and several varieties are distinguished on the basis of alteration characteristics and position within the deposit: 1) an intensely quartz-veined phase that occurs along the upper margin of the main intrusive body or as a separate east-dipping tabular body in the overlying strata; 2) a gold-rich phase, restricted to the western part of the main intrusion in the northern part of the Hugo North deposit; and 3) the main intrusive body, which typically has lower vein density and lower copper and gold grades. Cross-cutting relationships between the different phases are ambiguous, and it is uncertain whether they represent a temporally distinct intrusive events or simply variations in alteration intensity related to position within the deposit. Late- to post-mineral biotite granodiorite intrusions form a voluminous, northerly-striking dyke complex cutting across the western edge of the deposit. Although these intrusions locally contain elevated copper grades adjacent to intrusive contacts or associated with xenolithic zones, they are essentially non-mineralized. The positions and orientations of dyke contacts are now well established in the Hugo North deposit area on the basis of correlations between drill hole intersections and measurements of individual contacts using oriented drill core. Dominant dyke orientation varies with depth. At levels above approximately 250 m, where it cuts through the non-mineralized hangingwall strata, the biotite granodiorite occurs as a single intrusive mass with contacts dipping moderately to steeply to the west. Below this level, the biotite granodiorite is more complex, occurring as multiple, subparallel to anastamosing dykes that cut through the quartz monzodiorite intrusion and mineralized Alagbayan Formation strata. Drill hole correlation suggests May 2005 PAGE 7-24 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA that this lower portion contains a wide, steeply-dipping central dyke, from which emanate numerous moderately- to steeply-dipping apophyses. Younger intrusions include rhyolitic, hornblende biotite andesite, dacite, and basalt/dolerite compositional varieties. These intrusions usually occur as dykes with subvertical orientations or less commonly as easterly-dipping sills emplaced along stratigraphic contacts. They are non-mineralized and not volumetrically significant in most of the deposit. STRUCTURAL GEOLOGY The Hugo North deposit occurs within easterly-dipping homoclinal strata contained in a north-northeasterly elongate fault-bounded block. The northern end of this block is cut by several northeast-striking faults near the northern boundary of the Oyu Tolgoi property, but the deposit remains open along trend north of these faults. Other than these northeasterly faults, the structural geometry and deformation history of the Hugo North deposit are similar to those of the Hugo South deposit. Deformation of the Hugo North deposit is dominated by brittle faulting (Figures 7-5 and 7-6). Major faults cutting the deposit can be grouped on the basis of orientation into four sets: 1) east-west-striking, moderately north-dipping faults (110 Fault); 2) steep north-northeast-striking faults (East and West Bat, East Hugo, and Axial faults); 3) north-northeast-striking, moderately east-dipping faults subparallel to lithologic contacts (Contact, Lower faults); and 4) the east-northeast-striking faults cutting across the northern end of the deposit (Boundary Fault System). 110 Fault The 110 Fault defines the division between the Hugo North and Hugo South deposits. The Hugo North deposit diminishes in size and grade southward approaching the fault. The characteristics and interpretation of the 110 Fault are summarized above in the description of the Hugo South deposit. Deposit-Parallel Faults Moderately east-dipping faults at the Hugo North deposit include the Contact Fault and the Lower Fault. The Contact Fault is a bedding-parallel detachment zone that normally occurs at the transition between the dacite tuff (middle Alagbayan Formation) and the overlying basalt/sediment cover sequence. The structural character of the Contact Fault at Hugo North is similar to that described above for the Hugo South area. The Contact Fault does not significantly displace the biotite granodiorite dyke contact, implying that movement following emplacement of this intrusion was minor.

It often coincides with the upper contact of the easterly-dipping portion of the biotite granodiorite dyke and extends updip within the dyke as well. In many drill holes, the Lower Fault occurs at an abrupt downhole discontinuity in copper and/or gold grades, indicating that latest movement displaced mineralized zones. Cross-sections through the Hugo North gold zone show apparent thrust offsets of around 300 m to 400 m, based on displaced high gold grades. West Bat Fault The subvertical, north-northeast-striking West Bat Fault occurs along the west side of the Hugo North deposit and cuts the western edge of the northern part of the deposit. Its orientation and structural character are similar to those at Hugo South, except that it splays upwards and northwards into several subparallel strands. Drill hole intersections in the northern part of Hugo North indicate an irregular fault surface, although this irregularity may be in part due to inaccurate surveys, compounded by the great depths of the fault-piercing points. The West Bat Fault is truncated at its northern end by the northeast-striking Boundary Fault System. The stratigraphic offset of the base of the upper Sainshandhudag Formation across the West Bat Fault is over 1,500 m. The fault movement direction is unknown, and the total offset may be significantly greater than the stratigraphic offset. East Bat Fault The north-northeast-striking East Bat Fault follows the east flank of the Hugo Dummett deposit, well east of the known deposit extents. It is intersected in only three drill holes at Hugo North, all of which are in the southernmost part of the deposit. The fault is assumed to continue northward along the edge of the deposit, but its existence is unproven. Based on constraints in the Hugo South area, the East Bat Fault has several hundred metres of apparent east-side-down displacement. East Hugo Fault The East Hugo Fault can be traced northward from the Hugo South deposit up to approximately Section 4767500N. In the southern and central part of Hugo North, it cuts across stratigraphic contacts at moderate angles and forms a sharp break in alteration intensity and copper grade. The fault gradually loses expression northward, suggesting a gradual decrease in displacement. The East Hugo Fault strikes north to north-northwest (subparallel to the deposit trend) and dips steeply to the east. The northernmost segment has a slightly more northerly strike than the fault to the south. The fault cuts and displaces mineralization, and there is no evidence that the fault was present at the time of mineralization. May 2005 PAGE 7-28 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Northeast-Striking Faults (Boundary Fault, Others) Several northeast-striking faults cut across the northern end of the Hugo North deposit near where it crosses the Oyu Tolgoi property boundary. These include the North Boundary Fault, which juxtaposes carboniferous granitic rocks against carboniferous strata to the south, an unnamed, more gently-dipping splay of the North Boundary Fault, and the Boundary Fault, which occurs slightly to the south. The North Boundary Fault has been intersected in several drill holes and usually occurs as a zone of intensely developed, foliated clay gouge up to several tens of metres wide. Its strike varies from east-northeast to nearly north-south, but dips are consistently around 70(degree) to the northwest. The Boundary Fault follows the intrusive contact of the granitic complex in the northwest part of the Oyu Tolgoi Property and likely represents reactivation of that surface during regional deformation. A moderately northwest-dipping splay of the North Boundary Fault juxtaposes carboniferous strata over the deposit sequence in several drill holes in the northern part of the property. This splay diverges upward from the North Boundary Fault well above the level of mineralization and thus does not cut the deposit. The steep, northeast-striking Boundary Fault juxtaposes strongly-mineralized rocks against post-mineral carboniferous strata near the northern property boundary. This fault truncates the West Bat Fault and likely displaces it and the northern end of the Hugo North deposit to the northeast. At higher levels, the Boundary Fault is cut by the splay of the North Boundary Fault. Folding History Bedding measurements indicate that fold style and orientation in the Hugo North deposit are similar to those at Hugo South, with most folding restricted to the upper part of the Alagbayan and overlying Sainshandhudag Formation. The inverted sedimentary facing directions found in the upper part of the Alagbayan Formation at Hugo South occur at similar stratigraphic levels at Hugo North. However, at Hugo North, they define tight folds that are clearly truncated by the biotite granodiorite dyke. This narrowly restricts the age of folding to Late Devonian, in roughly the same time period as mineralization. May 2005 PAGE 7-29 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 8 - DEPOSIT TYPES The Oyu Tolgoi deposits display copper-gold porphyry and related high-sulphidation copper-gold deposit styles. Copper-gold porphyry deposits are low-grade bulk tonnage deposits, where copper sulphides are finely disseminated or deposited in anastamosing veins and fractures in a large volume of rock. These deposits are amenable to large-scale open-pit or underground bulk mining methods. The Oyu Tolgoi deposits are older than typical porphyry copper systems and as a result have been subjected to post-mineral deformation associated with terrane accretion and intracontinental deformation events. Recognition of how this deformation has affected the form and distribution within the deposits has been an important factor in both exploration and resource modelling. One aspect of the deformational history that is unusual in porphyry systems involves large-scale rotation of the deposits from their original positions. Several lines of evidence suggest that the deposits have undergone moderate amounts (30(degree) to 60(degree)) of easterly tilting since their formation: - Post-mineral carboniferous strata flanking the deposits are folded but show consistent easterly to northeasterly dip directions, subparallel to those in the underlying Devonian strata. This implies that despite the time gap between the sequences, there is little angular discordance at the unconformity, and therefore the porphyry deposits formed within gently-dipping Devonian strata. - The distribution of alteration, copper and gold grades, and sulphides in the Hugo Dummett deposit are most consistent with a source below and to the west of the deposit axis. - In the Central and Southwest deposits, mineralized veins and high-grade core zones are more vertical than their present orientations if the enclosing Devonian strata are considered to have been subhorizontal during deposit formation. The Oyu Tolgoi porphyry copper deposits display a range in mineralization styles, alteration characteristics, and deposit morphologies despite having formed in close spatial and temporal association. These distinctions likely reflect differences in structural controls, host rock lithology, and depth of formation. Structural influences account for the most part for the differences in shape and distribution of mineralization within the deposits. In general, high-sulphidation mineralization and associated advanced argillic alteration are most common within the dacite tuff, the upper parts of the quartz monzodiorite, where it intrudes to levels high in the stratigraphic succession, and in narrow structurally controlled zones. In contrast the more typical copper-gold porphyry style alteration and mineralization tend to occur at deeper levels, predominantly within basalt and quartz monzodiorite. The Southwest deposit, particularly the gold-rich core zone, occurs as a steep cylindrical body typical of many porphyry copper deposits. Southwest is localized within a dilational transfer zone linking movement between the northeast-striking West Bounding and East Bounding faults. The strong structural control exerted by these faults is reflected in the abundant sheeted veins showing a May 2005 PAGE 8-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA high degree of preferred orientation, the pipe-like form of the gold-rich core to the deposit, and the spreading of low-grade copper and gold values along the bounding fault zones. The Central deposit occupies a structurally intact block within which no significant internal fault disruption has been identified. It forms an irregular to slightly funnel-shaped zone of mineralization characterized by high-sulphidation (pyrite-covellite-chalcocite-enargite) and copper-gold (chalcopyrite-gold) porphyry styles, as well as a chalcocite enrichment blanket. Although the preferred orientation of quartz veins implies strong structural control within the deposit, the geometry of intrusive phases is irregular. Weathering of the Central deposit has produced an oxide zone 40 m to 60 m thick, usually devoid of mineralization, overlying a chalcocite enrichment zone up to 80 m thick. The South and Wedge deposits are located on the eastern flank of the north-northeast-trending mineralized corridor at Oyu Tolgoi, within several structural blocks cut and bounded by minor northeast-striking subvertical faults. Despite the numerous faults cutting these deposits, the lesser degree of preferred vein orientation relative to other deposits implies that structural control was weaker during mineralization. The Hugo Dummett deposits have several features unusual to porphyry copper systems, including: 1) the anomalously high copper and gold grades, particularly in the northern part; 2) an unusually weakly altered pre-mineral sedimentary cover sequence that lies just above the porphyry system; 3) quartz + sulphide vein contents always exceeding 15%, and commonly over 90%, in the high-grade portion of the deposit; and 4) a highly-elongate gently-plunging tabular shape to the high-grade stockwork system. The formation of the high-grade portion of the Hugo Dummett deposits as a tabular, intensely veined, subhorizontal body contrasts markedly with most porphyry copper deposits, which tend to have steep, roughly cylindrical or elongate forms. This unusual form likely results from at least two geological influences: 1) the presence of low-permeability overlying sedimentary rocks; and 2) emplacement within a passive to slightly compressional horizontal stress regime, synchronous with thrust faulting. Both of these factors would serve to inhibit the upward migration of hydrothermal fluids, leading to the formation of a broad subhorizontal zone of fluid overpressuring and attendant hydraulic fracturing and vein formation. This fluid trapping likely also contributed to the unusually high copper grades in these deposits. May 2005 PAGE 8-2 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 9 - MINERALIZATION 9.1 SOUTHERN OYU DEPOSITS 9.1.1 SOUTHWEST DEPOSIT Copper-gold porphyry style mineralization at the Southwest deposit consists of a cylindrical high-grade core roughly 250 m in diameter enclosed within a broad zone of lower-grade mineralization. The high-grade core is centred on a 10 m to 30 m wide, vein-rich quartz monzodiorite dyke and extends for over 100 m into the adjacent massive porphyritic augite basalt. The high-grade core is characterized by 1 cm to 50 cm wide contorted milky white quartz veins in sericite, albite, minor tourmaline altered quartz monzodiorite and biotite-magnetite altered augite basalt, overprinted by chlorite + sericite. Chalcopyrite with subordinate pyrite, bornite, and molybdenite occur as late veinlets filling fractures in quartz veins and disseminated through wall rocks. Low-grade copper mineralization peripheral to the high-grade core is characterized by lower vein densities, hosted in chlorite+epidote altered basalt and lesser sericite+albite altered quartz monzodiorite. Magnetite veinlets post-date the quartz veins but predate the main sulphide event. Chalcopyrite, bornite, and pyrite are mainly disseminated, with fracture or vein controlled sulphides being less prominent. These peripheral zones include the informally defined Far South zone, which encompasses mineralized basalt with 1:1 gold copper ratios on the southwest margin of the deposit area, and the Bridge zone, consisting of copper mineralized basalt and quartz monzodiorite between the Southwest and Central deposits. Although these two subzones are used in resource modeling, there is no clear geological boundary distinguishing them from the adjacent peripheral zone mineralization. Gold in the Southwest deposit is closely associated with chalcopyrite, and occurs intergrown with chalcopyrite, as inclusions and fracture infills within pyrite, or on grain boundaries of pyrite. Lesser gold occurs on grain boundaries with bornite or as inclusions in bornite, quartz or carbonate. The gold to copper ratios range from 2:1 to 3:1 within the high-grade core, decreasing to 1:1 in the low-grade margins of the deposit. The Southwest deposit is capped by an oxidized zone that varies from 50 m to 60 m thick, and consists of black copper oxide (neotocite or tenorite) as fractures coatings and speckled throughout the oxidized limonite stained basalt. Alteration styles at the Southwest deposit are typical of copper-gold porphyry systems. Augite basalt in the high-grade core of the deposit contains biotite + magnetite alteration, overprinted by chlorite + sericite. Biotite alteration occurs pervasively in the core of the deposit and grades outwards to selvage controlled within pervasive chlorite + epidote alteration. Minor albite alteration occurs as selvages along veins or fractures. Locally brown carbonate alteration is present in the basalt. May 2005 PAGE 9-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA Vein-rich quartz monzodiorite (OT-Qmd and xQmd phases) in the high-grade core contains sericite + biotite + albite alteration with minor tourmaline and montmorillonite. Pink albite alteration commonly occurs as selvages on veins or fractures, and sericite overprints biotite and albite. In the low-grade peripheral portions of the deposit, augite basalt is pervasively chlorite + magnetite altered, with epidote occurring in patches and sericite and pink albite on vein or fracture selvages. Pink albite may form reaction rims around irregularly shaped epidote patches. Biotite alteration occurs locally. Late calcite or ankerite veins cross-cut the assemblage. Quartz monzodiorite within the low-grade margin contains pervasive sericite alteration, with albite occurring along quartz vein or fracture margins. Spotty biotite alteration occurs locally. 9.1.2 SOUTH DEPOSIT Mineralization in the South deposit is hosted dominantly in quartz monzodiorite in the southwestern portion of the deposit, in basalt throughout the central portion of the deposit, and in a minor zone of dacite tuff on the northern margin. Contorted quartz veins are present at South, but there is no clearly defined zone of high quartz vein density such as at the Southwest deposit. Consequently, fracture-controlled sulphide veins are minor, and sulphides occur dominantly as disseminated chalcopyrite, bornite, and molybdenite. Chalcopyrite is the principal copper sulphide, but in higher-grade areas bornite locally exceeds chalcopyrite in abundance. Magnetite occurs disseminated and as veins. Small zones with elevated gold values occur locally. A small zone of high sulphidation mineralization occurs within a quartz monzodiorite breccia in the western part of the deposit, adjacent to the South Fault. Mineralization here consists of pyrite, chalcopyrite, bornite, covellite, and primary chalcocite in quartz sericite kaolinite alteration, with late dickite veins. An oxide zone approximately 60 m thick overlies the South deposit and consists of malachite, azurite, cuprite, chrysocolla, neotocite, or tenorite hosted within basalt and quartz monzodiorite. Alteration within the basaltic rocks at South consists of moderate chlorite, biotite hematite/magnetite, weak sericite, and pink albite fracture and vein selvages. Hematite overprints magnetite. Quartz monzodiorite is typically pervasively altered with quartz, sericite, and pyrite, as well as albite within vein selvages, small radiating clusters of tourmaline, and fluorite in quartz veins. Advanced argillic alteration consisting of quartz, sericite, and kaolinite with late dickite veins is associated with the high-sulphidation mineralization in the quartz monzodiorite breccia. 9.1.3 WEDGE DEPOSIT The Wedge deposit contains a zone of high-sulphidation mineralization hosted principally in dacite tuff, grading downward and southward into chalcopyrite mineralization in basalt and quartz monzodiorite host rocks. May 2005 PAGE 9-2 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA High-sulphidation mineralization consists of pyrite, chalcopyrite, bornite, enargite, covellite, and primary chalcocite in advanced argillically altered host rocks. Higher grades of copper (>0.8% Cu) occur in a shallowly east-dipping zone in the upper hundred metres of dacite tuff. Gold is absent, except locally in drill holes adjacent to the South Fault. Mineralization is open down dip and to the north. High-sulphidation mineralization grades downward into chalcopyrite, with lesser bornite within basalt host rocks, and pyrite + chalcopyrite mineralization in quartz monzodiorite. Dacite tuff within the Wedge deposit is characterized by advanced argillic alteration consisting of kaolinite, zunyite, pyrophyllite, muscovite, illite, topaz, diaspore, alunite, montmorillonite, late dickite, and fluorite. A barren, specular, hematite-rich zone occurs marginal to advanced argillic alteration and is progressively overprinted by advanced argillic alteration assemblages with increasing copper grades towards the centre of the deposit. The advanced argillic alteration grades downward into biotite + chlorite alteration with hematite overprinting magnetite, mainly within basalt host rocks underlying the dacite tuff. In the southern part of the Wedge deposit, sericite + pyrite alteration occurs within the quartz monzodiorite. 9.1.4 CENTRAL DEPOSIT Mineralization in the Central deposit is characterized by an upward-flaring, high-sulphidation zone that overprints and overlies porphyry-style chalcopyrite-gold mineralization. A secondary-enriched supergene chalcocite blanket tens of metres in thickness overlies the high-sulphidation covellite-pyrite zone. Chalcopyrite-gold mineralization is dominant on the south and western margins of Central within either basalt or quartz monzodiorite adjacent to intrusive contacts with basalt. Higher grades are associated with zones of intensely contorted quartz stockwork veins, where the gold (ppm) to copper (%) ratios reach 2:1. Peripheral, lower-grade mineralization has gold:copper ratios of less than 1:1. Hematite, pyrite, chalcopyrite, bornite, magnetite, and gold occur disseminated in the zone and as fracture fillings. Hematite is pervasive and overprints magnetite. The high-sulphidation part of the Central deposit lacks significant gold and contains a mineral assemblage of pyrite, covellite, chalcocite/digenite, enargite, tennantite, cubanite, chalcopyrite, and molybdenite. Dominant host rocks are dacite tuff and quartz monzodiorite. Higher-grade mineralization is associated with disseminated and coarse-grained fracture-filling sulphides in zones of intense contorted quartz stockwork veins and anastamosing zones of hydrothermal breccias. Hydrothermal breccia consists of quartz vein and quartz monzodiorite fragments within an intensely sericitized matrix. The sulphide-filled fractures cut both the quartz veins and enclosing wall rock. High-grade mineralization grades outward to a broad, weakly veined, low-grade halo of dominantly disseminated sulphides. Pyrite, chalcopyrite, bornite, and enargite occur here as relic grains replaced by chalcocite, and covellite, and pyrite also hosts small inclusions of covellite. Covellite, May 2005 PAGE 9-3 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA chalcocite and enargite occur as intimate intergrowths or as free disseminations. Cubanite and tennantite occur intergrown with or replacing enargite, and molybdenite occurs locally in quartz. A supergene enrichment zone overlies the high sulphidation assemblage and underlies a 20 m to 60 m thick, hematitic limonite, goethite-rich leached cap. The supergene zone consists of pyrite, hematite, and chalcocite/digenite, with lesser amounts of colusite, enargite, tenorite, covellite, bornite, chalcopyrite, cuprite, and molybdenite. Pyrite is the dominant sulphide and occurs as disseminated crystals. Sooty chalcocite occurs as rims or microveinlets in pyrite and covellite, and as independent disseminations. Colusite occurs as single grains or intergrown with chalcocite/digenite and/or pyrite. Tenorite occurs interstitial to silicate-iron oxide grain boundaries. Micrograins of chalcopyrite replaced by bornite and covellite occur as small inclusions within pyrite. Minor exotic copper oxide mineralization occupies a bedrock depression on the northeastern flank of Central. Chrysocolla, malachite, and neotocite mineralization occur over a 400 m x 300 m area as a thin 2 m to 4 m thick layer at the base of the gravels. The leached cap is generally devoid of mineralization except off the eastern and southern flanks of the deposit, where patchy malachite and neotocite occur. Alteration in the Central deposit shows a close spatial relationship to mineralization and original host lithology. Biotite-chlorite and intermediate argillic alteration coincide with chalcopyrite-gold mineralization within basalt. Advanced argillic and sericite alteration coincides with the high-sulphidation mineralization within quartz monzodiorite and ignimbrite. The biotite-chlorite zone consists of an assemblage of biotite, chlorite, epidote, sericite, albite, carbonate, and anhydrite. Hematite and minor magnetite occurs in veins and disseminated. Biotite has been overprinted by chlorite and sericite, and magnetite has been altered to hematite. Anhydrite and carbonates occur as late veins. K-feldspar alteration increases at depth beneath Central, occurring as vein selvages within biotite-altered basalt. Intermediate argillic alteration forms a narrow zone separating the advanced argillic and sericite alteration from the biotite chlorite alteration. Intermediate argillic alteration is characterized by a creamy yellow to pale green coloured assemblage of kaolinite, chlorite, pyrophyllite, and illite. Advanced argillic and sericite alteration are associated with high-sulphidation mineralization, hosted primarily within dacite and quartz monzodiorite. The advanced argillic assemblage consists of topaz, quartz, zunyite, diaspore, alunite, illite, andalusite, late kaolinite, and dickite. There is a zonation from an advanced argillic assemblage of zunyite, andalusite, and alunite associated with higher-grade hydrothermal breccia-hosted mineralization, to a muscovite, sericite-dominant peripheral zone associated with lower-grade disseminated mineralization. Alteration within the supergene zone is characterized by illite, muscovite, kaolinite, alunite and pyrophyllite. Montmorillonite, smectite, kaosmectite, illite and kaolinite are the dominant clay minerals in the leached cap. May 2005 PAGE 9-4 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 9.2 HUGO DUMMETT DEPOSITS 9.2.1 HUGO SOUTH DEPOSIT Copper mineralization at the Hugo South deposit is centred on a high-grade (typically > 2% Cu) zone of intense quartz stockwork veining, which in much of the deposit is localized within narrow quartz monzodiorite intrusions and extends into the enclosing basalt and dacite tuff. The intense stockwork zone has an elongate tabular form, with a long axis plunging shallowly to the north-northwest, and an intermediate axis plunging moderately to the east. Copper grades gradually decrease upwards from the stockwork zone through the upper part of the basalt and the dacite tuff, and a broader zone of lower grades occurs below and to the west in basalt and quartz monzodiorite. Dominant sulphide minerals at Hugo South are chalcopyrite, bornite, chalcocite, and pyrite, with minor molybdenite, enargite, tennantite, and covellite. Rarely, sphalerite and galena occur. Sulphides are zoned (Figure 9-1) with bornite +/- chalcopyrite, chalcocite, and tennantite comprising highest grades (>2.5% Cu), grading outwards to chalcopyrite (1% to 2% Cu). Pyrite-chalcopyrite +/- enargite, tennantite, bornite, chalcocite, and rarely covellite occur with low-grades (<1% Cu), mainly in advanced argillically altered dacite tuff. Drill hole assays (Cu, Au, Ag, As) and selected ICP-MS multi-element data (Pb, Zn, Se, Te, Tl, Bi) show distinct geochemical zoning coincident with sulphide zoning. copper shows a strong correlation with Au, Ag (up to 9 ppm), Se (up to 33 ppm), Bi, and, to a lesser extent, Tl. High As values (up to 2,850 ppm) occur mainly with high pyrite and enargite in the dacite tuff, and Zn (up to 3,530 ppm) occurs with chalcopyrite at the top of the mineralized zone. Alteration in the Hugo South deposit is typical of copper porphyry systems, including K-silicate (minor), advanced argillic, muscovite/sericite, and intermediate argillic styles. The mineral groupings used to define individual zones are not necessarily true assemblages that formed contemporaneously, but are associations that may represent several paragenetic stages. The following alteration zones have been defined at Hugo South (Figure 9-2): - Chlorite-illite alteration occurs in the uppermost part of the dacite tuff. This alteration is not texturally destructive, and primary volcanic textures are clearly visible. No mineralization is associated with this weak outermost alteration zone. - Advanced argillic alteration is dominant in the dacite tuff and is characterized by the minerals quartz, pyrophyllite, kaolinite, topaz, diaspore, zunyite, alunite, and dickite. Because the advanced argillic alteration is widespread and consists of a complex mineral assemblage, it is divided into subzones: - Pyrophyllite-kaolinite: This is the most widespread subgroup of the advanced argillic alteration. It occurs dominantly in the dacite tuff, but also in the upper parts of the basalt and quartz monzodiorite. Late white to pink dickite on fractures is ubiquitous.

The lenses are parallel to, and occur just above and east of, the high-grade, vein-rich deposit core. It is whitish-pink to brown in colour. - Topaz alteration occurs as an intense, completely texturally destructive zone and is typically of limited extent. Topaz-altered zones are vuggy and whitish-brown in colour. They are most common in the dacite tuff, but occur locally in the basalt. May 2005 PAGE 9-7 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA - Pyrophyllite-kaolinite-dickite-muscovite/illite (intermediate argillic) alteration occurs in the upper parts of the basalt at the contact with the dacite tuff and is the dominant alteration type in the high-grade deposit core. It is brownish-yellow in colour but turns pinkish where pyrophyllite is the dominant mineral. It is not texturally destructive. Hematite is common as fine specularite. - Chlorite-muscovite/illite-hematite alteration is the dominant alteration in the basalt. It is characterized by its green colour, and the original texture of the basalt is still visible (e.g., relict pseudo-hexagonal augite crystals). Locally, particularly at depth, biotite occurs in the zone. Relict magnetite occurs either disseminated or in veins. - Muscovite/illite alteration occurs mainly in quartz monzodiorite intrusions. It is pale green to gray in colour and in most cases texturally destructive, although in places original feldspar crystals can still be observed. Locally, topaz occurs with muscovite, and a subgroup of muscovite-topaz alteration was recognized. The distribution of the alteration is strongly lithologically controlled: dacite tuff typically shows strong advanced argillic alteration, whereas basalt tends to be chlorite-muscovite-hematite altered with pyrophyllitic advanced argillic alteration in its uppermost parts. Pockets of advanced argillic alteration occur locally in the high-grade zone in the quartz monzodiorites. 9.2.2 HUGO NORTH DEPOSIT The highest-grade copper mineralization in the Hugo North deposit is related to a zone of intense stockwork to sheeted quartz veins. The high-grade zone is centred on thin, east-dipping quartz monzodiorite intrusions or within the upper part of the large quartz monzodiorite body, and extends into the adjacent basalt. In addition, moderate to high-grade copper and gold values occur within quartz monzodiorite below and to the west of the intense vein zone, in the Hugo North gold zone. This zone is distinct in its high Au (ppm) to Cu (%) ratios (0.5:1). In other respects the Hugo North and Hugo South deposits have similar mineralogy and zonation patterns. Bornite is dominant in highest-grade parts of the deposit (3% to 5% Cu) and is zoned outward to chalcopyrite (2%). At grades of <1% Cu, pyrite-chalcopyrite +/- enargite, tennantite, bornite, chalcocite, and rarely covellite occur, hosted mainly by advanced argillically altered dacite tuff. The high-grade bornite zone comprises relatively coarse bornite impregnating quartz and disseminated in wall rocks, usually intergrown with subordinate chalcopyrite. Pyrite is rare or absent, except in local areas where the host rocks are advanced argillically altered. Whereas chalcocite is commonly found with bornite at Hugo South, it is less common at Hugo North. In addition, high-grade bornite is associated with minor amounts of tennantite, sphalerite, hessite, clausthalite, and gold. These minerals occur as inclusions or at grain boundaries. Elevated gold grades in the Hugo North deposit occur within the up-dip (western) portion of the intensely veined, high-grade core, and within a steeply-dipping lower zone cutting through the western part of the quartz monzodiorite. Quartz monzodiorite in the lower zone exhibits a May 2005 PAGE 9-8 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA characteristic pink to buff colour, with a moderate intensity of quartz veining (25% by volume). This zone is characterized by finely disseminated bornite and chalcopyrite, although in hand specimen the chalcopyrite is usually not visible. The sulphides are disseminated throughout the rock in the matrix as well as in quartz veins. The fine-grained sulphide gives the rocks a black "sooty" appearance. The red colouration is attributed to fine hematite dusting, mainly associated with albite. Similar to Hugo South, copper in the Hugo North deposit correlates with elevated abundances of Ag, Se, and Te. Arsenic occurs at low levels in the high-grade zone and is related to tennantite. Zinc (about 300 ppm) occurs mainly as sphalerite. Se and Te are attributed to hessite and clausthalite inclusions in bornite. Pb occurs at levels of up to several hundred ppm peripheral to the high-grade zone in dacite tuff. Low levels of Hg (0.2 ppm) occur in the upper part of the ore body. The Hugo North deposit is characterized by copper-gold porphyry and related styles of alteration similar to those at Hugo South (Figure 9-3). This includes biotite-K-feldspar (K-silicate), magnetite, chlorite-muscovite-illite, albite, chlorite-illite-hematite-kaolinite (intermediate argillic), quartz-alunite-pyrophyllite-kaolinite-diaspore-zunyite-topaz-dickite (advanced argillic), and sericite/muscovite zones. The distribution of alteration zones is similar to that in the Hugo South deposit, except that the advanced and intermediate argillic zones are more restricted and occur mainly along the northern margin of the intrusive system (Figure 9-3). - Chlorite-illite marks the outer boundary of the advanced argillic zone. It occurs mainly in the coarse, upper part of the dacite tuff. - Quartz-pyrophyllite-kaolinite-dickite (advanced argillic) is hosted mainly in the lower part of the dacite tuff, although on some sections at Hugo North it extends into strongly veined quartz monzodiorite. The advanced argillic zone is typically buff or grey, and late dickite on fractures is ubiquitous. Within the advanced argillic zone, a massive quartz-alunite zone forms a pink-brown bedding-parallel lens. - Topaz is widespread as late alteration controlled by structures cutting both the advanced and intermediate argillic zone. As illustrated by the type section, topaz appears to replace parts of the quartz-alunite zone. In addition topaz may also occur disseminated with quartz-pyrophyllite-kaolinite. Strong topaz zones are mottled buff or light brown and sometimes vuggy. - Hematite-siderite-illite-pyrophyllite-kaolinite-dickite (intermediate argillic) is an inward zonation from the advanced argillic zone, and is commonly hosted by augite basalt but may also occur in dacite ash flow tuff. Hematite usually comprises fine specularite and may be derived from early magnetite or Fe-rich minerals such as biotite or chlorite.

It is characterized by a green colour, and relict hydrothermal magnetite, either disseminated or in veins. - Muscovite-illite (sericite) generally occurs in the quartz monzodiorite intrusions and is a feature of the strongly mineralized zone. Alteration decreases with depth in the quartz monzodiorite. May 2005 PAGE 9-10 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 10 - EXPLORATION Exploration at Oyu Tolgoi has been mainly by remote sensing and geophysical methods, including satellite image interpretation, detailed ground magnetics, Bouguer gravity and gradient array induced polarization (IP), as well as extensive drilling. Gradient array IP has been conducted on north-south and subsequently east-west lines at 200 m line spacing, with electrode spacing up to 11 km. Drill holes have been targeted to test IP chargeability targets or structural zones. Outcropping prospects (Southwest, South, and Central) have been mapped at 1:1,000 scale. The central part of the exploration block was mapped at 1:5,000 scale in 2001, and the entire block was mapped at 1:10,000 scale in 2002. As described below, geophysical methods have been the most important exploration tool. Geophysical surveying at Oyu Tolgoi was first initiated by BHP in 1996. An airborne magnetometer survey was flown at a height of approximately 100 m on 300 m spaced, east-west oriented lines over approximately 1,120 km(2) of BHP's mineral concession. The survey provided good resolution of the magnetic features to facilitate geological and structural interpretation across the concession areas. BHP also undertook an induced polarization (IP) survey utilizing a single gradient array with a 2,000 m AB and a ground magnetometer survey. Both surveys were conducted on east-west-oriented lines surveyed by a local Mongolian surveying team at 250 m spacing. The surveys covered Southern, Southwest, Central, and North Oyu exploration targets but did not extend into the Far North region that ultimately became the Hugo Dummett deposit. Ivanhoe initiated geophysical exploration after the discovery of the high-grade, gold-rich portion of the Southwest Oyu zone in June 2001. The gold-rich, chalcopyrite-dominate mineralization discovered in drill hole OTRCD150 was clearly responsible for the IP chargeability anomalies previously delineated by the BHP survey. The presence of hydrothermal magnetite with the copper-gold mineralization was the probable source of the intense magnetic anomalies defined over SW Oyu and possibly South Oyu. Delta Geoscience of B.C., Canada, was mobilized to the property in the fall of 2001 to undertake detailed IP surveying utilizing gradient arrays with multiple electrode spacings to delineate the vertical extent of the sulphide mineralization being defined by drilling in SW Oyu. The detailed IP surveys initially covered a 3 km east-west x 4 km north-south block encompassing the Southwest, South, Central, and Far North target areas. At the same time Ivanhoe acquired two magnetometers and initiated very detailed ground magnetometer surveying using 5 m spaced readings along 25 m spaced, north-south oriented lines over the Southern Oyu target areas. An Ulaanbaatar-based geophysical team ultimately expanded this magnetic survey to cover the entire 8 km x 10 km concession. This group covered the northern half of the concession with east-west oriented lines on 50 m intervals with 25 m spaced readings. In 2002 the geophysical program was further expanded to include a gravity survey over the Oyu Tolgoi concession block. The survey was controlled by GPS with readings taken on 50 m centres over the core of the concession and 100 m centres over the extremities. The Bouger map was May 2005 PAGE 10-1 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA reduced to residual gravity for contouring. Unfortunately no additional processing or modelling of the data has been carried out. With the density measurements that have been taken on drill core through out the deposits, detailed computer modelling of the gravity data should be possible. Telluric Electromagnetic (TEM) surveying was also conducted over the eastern half of the concession in conjunction with extensive TEM surveying used to define the Cretaceous-aged, semi-consolidated sedimentary basins along the Galbyn Gobi and Gunii Holloi valleys, southeast and northeast, respectively, from Oyu Tolgoi. These basins developed along the East Mongolian Fault system and a splay off of the fault, and form the reservoirs for extensive water resources required to operate the Oyu Tolgoi mine. On the Oyu Tolgoi concession, the TEM work was designed to delineate smaller drainage basins that could have channelled copper-rich surficial waters from the exposed copper deposits during the Cretaceous period. These "pregnant waters" could potentially have precipitated copper into river gravels down stream to form secondary "exotic" copper deposits. Diamond drilling ultimately has been the primary tool of exploration at Oyu Tolgoi. To the beginning of May 2005, more than 1,000 drill holes have been completed, many of which in the Hugo North deposit were multiple daughter holes navi-drilled from a single parent. Approximately 546,000 m of core has been collected and stored on the property. The amount of drilling in the individual deposit areas is tabulated below. Total Diamond Core Drilling....................................... 546,000 Hugo Dummett Deposit.............................................. 249,000 Central & Bridge.................................................. 95,000 Southwest......................................................... 139,000 South & Wedge..................................................... 62,000 Other............................................................. 22,000 Entree - Ivanhoe JV .............................................. 9,000 May 2005 PAGE 10-2 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 11 - DRILLING Diamond drill holes are the principal source of geological and grade data for the Oyu Tolgoi project. Ivanhoe conducted diamond drilling over the Southern Oyu deposits throughout 2003 (Central and Southwest) and 2004 (Southwest, South, and Wedge). Drilling on the Hugo Dummett deposit concentrated on the Hugo North deposit in 2004 and 2005. As of the mineral resource cutoff date of 15 April 2005, drilling totals just under 273,000 m in 583 drill holes for the Southern Oyu deposits and 200,000 m in 156 drill holes, including daughter holes, for Hugo North. The Southern Oyu holes generally range in length from 60 m to 1,200 m, averaging 470 m. The Hugo North holes range from 400 m to 2,200 m and average 1,280 m in length. A list of the project drill holes, together with their coordinates and lengths, is provided in Appendix A, along with location plans. Drilling was done by wireline method with H-size (HQ, 63.5 mm nominal core diameter) and N-size (NQ, 47.6 mm nominal core diameter) equipment using up to 20 drill rigs. Upon completion, the collar and anchor rods were removed and a PVC pipe was inserted into the hole. The hole collar was marked by a cement block inscribed with the hole number. Hugo North drilling almost always include multiple daughter holes drilled from the parent drill hole. A bend was placed in the parent hole at the location where the planned daughter holes were to branch off. The bend was achieved by means of a Navi-Drill(R) (navi) bit, which was lowered down the hole to the desired depth and aligned in the azimuth of the desired bend. As the navi bit advanced, a bend was achieved at the rate of 1(degree) every 3 m. No core was recovered fROm the navi-drilled interval. Drill hole collars were located respective to a property grid. Proposed hole collars and completed collars were surveyed by a Nikon Theodolite instrument relative to 18 survey control stations established during a legal survey of the property in 2002. The drill holes were drilled at an inclination of between 45(degree) and 90(deGRee), with the majority between 60(degree) and 70(degree). Holes weRE drilled along 035(degree) and 125(degree) azimuths in Southwest aND South, 0(degree) and 180(degree) azimuths in Central. Down-hole surveys wERe taken approximately every 50 m by the drill contractor using a multi-shot measurement system (RANGER survey instrument). Standard logging and sampling conventions were used to capture information from the drill core. The core was logged in detail onto paper logging sheets, and the data were then entered into the project database. The core was photographed before being sampled. AMEC reviewed the core logging procedures at site, and the drill core was found to be well handled and maintained. Material was stored as stacked pallets in an organized "core farm." Data collection was competently done. Ivanhoe maintained consistency of observations from hole to hole and between different loggers by conducting regular internal checks. Core recovery in the mineralized units was excellent, usually between 95% and 100%. Very good to excellent recovery was observed in the mineralized intrusive sections checked by AMEC. Overall, the Ivanhoe drill program and data capture were performed in a competent manner. May 2005 [AMEC LOGO] PAGE 11-1 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 12 - SAMPLING METHOD AND APPROACH Rock sampling for resource estimation has been conducted on diamond drill core obtained from holes drilled between May 2001 and April 2005. Samples are taken at 2 m intervals down the drill holes, excluding dykes that extend more than 10 m along the core length. NQ and HQ core sizes are drilled routinely, with one-half of the core collected for analysis. The core is split with a rock saw, flushed regularly with fresh water. Core recovery is good, with relatively few broken zones. To minimize sampling bias, the core is marked with a continuous linear cutting line before being split. Samples are placed in cloth bags and sent to the on-site preparation facility for processing. Reject samples are stored in plastic bags inside the original cloth sample bags and are placed in bins on pallets and stored at site. Duplicate pulp samples are stored at site in the same manner as reject samples. Pulp samples used for assaying are kept at the assaying facility for several months and then transferred to a warehouse in Ulaanbaatar. Significant composited assays for the Southern Oyu and Hugo North deposits are shown in Appendix B. Only values equal to or above 1.0% copper equivalent grade were tabulated. May 2005 [AMEC LOGO] PAGE 12-1 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 13 - SAMPLE PREPARATION, ANALYSES, AND SECURITY 13.1 SAMPLE PREPARATION AND SHIPMENT Split core samples are prepared for analysis at an on-site facility operated by SGS Mongolia LLC (SGS Mongolia). The samples are then shipped under the custody of Ivanhoe to Ulaanbaatar, where they are assayed at a lab facility operated by SGS Mongolia. All sampling and QA/QC work is overseen on behalf of Ivanhoe by Dale A. Sketchley, M.Sc., P.Geo. The samples are initially assembled into groups of 15 or 16, and then 4 or 5 quality control samples are interspersed to make up a batch of 20 samples. The quality control samples comprise one duplicate split core sample, one uncrushed field blank, a reject or pulp preparation duplicate, and one or two standard reference material (SRM) samples (one < 2% Cu and one >2% Cu if higher-grade mineralization is present based on visual estimates). The two copper SRMs are necessary because SGS Mongolia uses a different analytical protocol to assay all samples >2% Cu. The split core, reject, and pulp duplicates are used to monitor precision at the various stages of sample preparation. The field blank can indicate sample contamination or sample mix-ups, and the SRM is used to monitor accuracy of the assay results. The SRMs are prepared from material of varying matrices and grades to formulate bulk homogenous material. Ten samples of this material are then sent to each of at least seven international testing laboratories. The resulting assay data are analyzed statistically to determine a representative mean value and standard deviation necessary for setting acceptance/rejection tolerance limits. Blank samples are also subjected to a round-robin program to ensure the material is barren of any of the grade elements before they are used for monitoring contamination. A total of 38 different reference materials have been developed and combined with two commercially purchased ones, used to monitor the assaying of six different ore types made up of varying combinations of chalcopyrite, bornite, primary and supergene chalcocite, enargite, covellite, and molybdenite. Split core samples are prepared according to the following protocol: - The entire sample is crushed to 90% minus 3 mm. - A 1 kg subsample is riffle split from the crushed minus 3 mm sample and pulverized to 90% minus 75 um (200 mesh). - A 150 g subsample is split off by taking multiple scoops from the pulverized 75 um sample. - The 150 g subsample is placed in a kraft envelope, sealed with a folded wire or glued top, and prepared for shipping. May 2005 [AMEC LOGO] PAGE 13-1 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA All equipment is flushed with barren material and blasted with compressed air between each sampling procedure. Screen tests are done on crushed and pulverized material from one sample taken from each batch of 15 or 16 samples to ensure that sample preparation specifications are being met. Prepared samples are placed in wooden shipping boxes, locked, sealed with tamper-proof tags, and shipped to Ulaanbaatar for assaying. Sample shipment details are provided to the assaying facility both electronically and as paper hard copy accompanying each shipment. The assaying facility then electronically confirms sample receipt, the state of the tamper-proof tags, and assigned laboratory report numbers back to site. 13.2 ASSAY METHOD All samples are routinely assayed for gold, copper, and molybdenum. Gold is determined using a 30 g fire assay fusion, cupelled to obtain a bead, and digested with Aqua Regia, followed by an AAS finish. Copper and molybdenum are determined by acid digestion of a 5 g subsample, followed by an AAS finish. Samples are digested with nitric, hydrochloric, hydrofluoric, and perchloric acids to dryness before being leached with hydrochloric acid to dissolve soluble salts and made to volume with distilled water. 13.3 QA/QC PROGRAM Assay results are provided to Ivanhoe in electronic format and as paper certificates. Upon receipt of assay results, values for SRMs and field blanks are tabulated and compared to the established SRM pass-fail criteria: - automatic batch failure if the SRM result is greater than the round-robin limit of three standard deviations - automatic batch failure if two consecutive SRM results are greater than two standard deviations on the same side of the mean. - automatic batch failure if the field blank result is over 0.06 g/t Au or 0.06% Cu. If a batch fails, it is re-assayed until it passes. Override allowances are made for barren batches. Batch pass/failure data are tabulated on an ongoing basis, and charts of individual reference material values with respect to round-robin tolerance limits are maintained. Laboratory check assays are conducted at the rate of one per batch of 20 samples, using the same QA/QC criteria as routine assays. May 2005 [AMEC LOGO] PAGE 13-2 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 13.3.1 STANDARDS PERFORMANCE Ivanhoe strictly monitors the performance of the SRM samples as the assay results arrive at site. The ability of the laboratories to return assay values in the prescribed SRM ranges has steadily improved to greater than 99% (Figure 13-1). Charts of the individual SRMs are included in Appendix C. All samples are given a "fail" flag as a default entry in the project database. Each sample is re-assigned a date-based "pass" flag when assays have passed acceptance criteria. At the data cutoff date of 15 April 2005, only a very small number of assayed samples still had the "fail" flag. The relative uncertainty introduced to the mineral resource estimate by using this very small number of temporarily failed samples is considered negligible. FIGURE 13-1: SRM FAILURE CHART [LINE GRAPH] 13.3.2 BLANK SAMPLE PERFORMANCE Assay performance of field blanks is presented in Appendix C for gold and copper. In these figures, the lower blue horizontal line represents the analytical detection limit (ADL) of the respective metal, and the upper yellow horizontal line represents the analytical rejection threshold (ART). The gold ADL is 0.01 g/t with an ART of 0.06 g/t; copper ADL was initially 0.01% and is now 0.001% with an ART of 0.06%. The results show a low incidence of contamination and a few cases of sample mix-ups, which were investigated at site and corrected. 13.3.3 DUPLICATES PERFORMANCE The QA/QC program currently uses four different types of duplicate samples: core, coarse reject, pulp, and laboratory check pulps (samples sent to an umpire lab). May 2005 [AMEC LOGO] PAGE 13-3 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA CORE, COARSE REJECT, AND PULP DUPLICATES AMEC has reviewed the core, coarse reject, and pulp duplicate samples for the Southern Oyu and Hugo Dummett deposits. The pulp and coarse reject duplicates reproduce well for copper and are reasonable for gold values greater than 0.2 g/t. The duplicate data are shown as relative difference charts in Appendix C. Pulp and reject duplicate types for each metal, though more so for gold, show similar high variability to good reproducibility trends from near detection values towards higher-grade value. Patterns for all metals are symmetric about zero, suggesting no bias in the assay process. The absolute relative percent difference for duplicate pairs against the percentile ranking of the grade in the sample population were also evaluated. For the 90th percentile of the population, a maximum difference of 10% is recommended for the pulp duplicates and 20% for the coarse reject duplicates because these duplicate types can be controlled by the subsampling protocol. The same criteria do not apply to core duplicates because these differences cannot be controlled by the subsampling protocol; however, the heterogeneity of the mineralization ideally would allow the difference to be less than 30%. Table 13-1 summarizes the results of these analyses for each type of sample, and the charts are shown in Appendix C. The core duplicates are above the ideal value of 30% for gold samples, whereas the coarse reject duplicates reproduce well for all elements. TABLE 13-1: PERCENT DIFFERENCE AT THE 90TH POPULATION PERCENTILE CU AU ----------------- ----------------- DUPLICATE TYPE % DIFF. LIMIT NO. % DIFF. NO. % DIFF. -------------------- ------------- ----- ------- ----- ------- Southwest, South and Wedge Deposits Core 30 2,898 38 2,771 60 Coarse Reject 20 1,371 14 1,095 25 Pulp 10 1,368 5 1,092 18 Central Deposit Core 30 2,898 38 2,771 60 Coarse Reject 20 1,371 14 1,095 25 Pulp 10 1,368 5 1,092 18 Hugo North Deposit Core 30 1,416 27 1,416 45 Coarse Reject 20 719 6 719 26 Pulp 10 696 4 696 21 Gold pulp duplicates mimic the reject duplicate results and likely point to some liberation of gold during sample preparation However, since most of the gold values lie near the detection limit, and the samples that are above 0.5 g/t show much better reproducibility than the overall rank analysis, AMEC recommends no changes to the current sampling protocol.

The specific gravity for non-porous samples (the most common type) is calculated using the weights of representative samples in water (W2) and in air (W1). The bulk density is calculated by W1/(W1-W2). AMEC believes this method to be appropriate for the non-porous mineralized units and barren dykes. Less-common porous samples are dried and then coated with paraffin before weighing. Allowance is made for the weight and volume of the paraffin when calculating the specific gravity. As a check on its method for specific gravity determinations, Ivanhoe submitted 120 samples to a commercial laboratory for independent testing. The results, reviewed by AMEC, show near-identical values to the original Ivanhoe numbers, and support the procedures and results of Ivanhoe's specific gravity program. 13.4 CONCLUDING STATEMENT In AMEC's opinion, the QA/QC results demonstrate that the Oyu Tolgoi project assay database for 2005 is sufficiently accurate and precise for resource estimation. May 2005 [AMEC LOGO] PAGE 13-5 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 14 - DATA VERIFICATION As a test of assay data integrity, the data used to estimate the 2005 Southern Oyu and Hugo North mineral resources were verified with a random comparison of 5% of the database records against the original electronic assay certificates. No discrepancies were found. Collar coordinates were checked against the database entries. No discrepancies were observed. AMEC also checked the down-hole survey data. Camera shots and RANGER output were read for the checked drill holes and compared to those stored in the resource database. Rare minor discrepancies were observed that are probably due to arbitrary corrections made to the data because of the suspected or measured presence of magnetite. These would have neglible impact on any resource estimate. AMEC concludes that the assay and survey database transferred to AMEC is sufficiently free of error to be adequate for resource estimation.

A major update to that study is near completion and should be disclosed later in 2005. May 2005 [AMEC LOGO] PAGE 16-1 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 17 - MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES The mineral resource estimates for the Oyu Tolgoi project were calculated under the direction of Dr. Harry Parker, Ch.P.Geol., and Dr. Stephen Juras, P.Geo. The estimates were made from 3D block models utilizing commercial mine planning software (MineSight(R)). The project consists of two groups of deposits: Hugo Dummett (Hugo) and Southern Oyu (OTS), each represented by its own resource model. Hugo comprises Hugo South (HS) and Hugo North (HN), and OTS contains four deposits: Southwest (SW), South (SO), Wedge (WZ), and Central (CO). Projects limits are in truncated UTM coordinates. Project limits are 650500 to 652500 East, 4765000 to 4768200 North, and -660 to +1170 m elevation for Hugo and 649500 to 652000 East, 4762000 to 4765000 North, and -225 m to +1,170 m elevation for OTS. Cell size for the project was 20 m east x 20 m north x 15 m high. The mineral resource for the Hugo South deposit was not re-estimated in this work. 17.1 GEOLOGIC MODELS Ivanhoe used significant new data from infill drilling at Hugo North and revised structural and intrusive rock interpretations based on ongoing geologic studies at Oyu Tolgoi as a whole to create new 3D shapes of key geologic surfaces, faults, and intrusive units. For Hugo (mainly Hugo North) the changes were major since the last disclosed resource and affected both geologic and structural features. In OTS, the changes were limited to a more consistent interpretation of post-mineral dykes in all deposits and a better definition of geologic contacts in the Wedge deposit. A list of key units and a brief comment on their relevancy to the resource models are provided in Table 17-1. AMEC checked the lithologic and structural shapes for interpretational consistency on section and plan, and found them to have been properly constructed. The shapes honoured the drill data and appear well constructed. Mineralized or grade shapes were also made. To constrain grade interpolation in each of the zones, AMEC and Ivanhoe created 3D mineralized envelopes, or shells. Most were based on initial outlines derived by a method of Probability Assisted Constrained Kriging (PACK). Threshold values were determined by inspection of histograms and probability curves as well as indicator variography. The shells were based on a copper or gold grade except for the high-grade copper zone in Hugo North, which was defined based on amount of quartz veining. The OTS gold shells were developed on threshold gold values of 0.7 g/t for Southwest and 0.3 g/t for Central and South. OTS copper shells (Southwest - Bridge area, Central, South, and Wedge) were based upon threshold values of 0.3% Cu. The higher-grade copper zone at Hugo North was defined by a quartz vein percentage threshold (15%). Shell outline selection was done by inspecting contoured probability values. These shapes were then edited on plan and section views to be consistent with the structural and lithologic models and the drill assay data so that the boundaries did not violate data and current geologic understanding of mineralization controls.

The copper shell was made at a grade threshold at 0.6% Cu, whereas the gold shells (Main and West) were drawn at a grade threshold of 0.3 g/t Au. May 2005 [AMEC LOGO] PAGE 17-2 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA AMEC checked the grade and mineralized shapes for interpretational consistency on section and plan, and found them to have been properly constructed. The shapes honoured the drill data and interpreted geology, and appear well constructed. The solids and surfaces were used to code the drill hole data. A set of cross-sections and plans with drill holes colour-coded by domain similarly coloured were plotted and inspected to determine the proper assignment of domain. 17.2 DATA ANALYSIS The lithologic, structural, and mineralized domains were reviewed in Hugo North and OTS to determine appropriate estimation or grade interpolation parameters. Several different procedures were applied to the data to discover whether statistically distinct domains could be defined using the available geological objects. For each zone, key lithologic categories were investigated within and outside grade shells. The mineralized volcanic and volcaniclastic units (basalt - DA1 or Va, and dacite ash flow tuff - DA2 or Ign) were separated in Hugo North but combined in the OTS deposits. The Qmd was treated as a distinct unit in the analysis, as was the quartz-veined and variable mineralized phases of the Qmd (OT-Qmd and the xenolithic Qmd) in the Southwest deposit. The mineralized xenolithic BiGd was also investigated in Hugo North. Descriptive statistics, histograms and cumulative probability plots, box plots and contact plots, and X-Y scatter plots have been completed for copper and gold in each area. Results obtained were used to guide the construction of the block model and the development of estimation plans. The data analyses were conducted on composited assay data: 5 m down-hole composites for OTS deposits and 15 m down-hole composites for Hugo North. 17.2.1 HISTOGRAMS AND CUMULATIVE FREQUENCY PLOTS Histograms and cumulative probability plots display the frequency distribution of a given variable and demonstrate graphically how that frequency changes with increasing grade. With histograms, the grades are grouped into bins, and a vertical bar on the graph shows the relative frequency of each bin. Cumulative frequency or cumulative distribution function (CDF) diagrams demonstrate the relationship between the cumulative frequency (expressed as a percentile or probability) and grade on a logarithmic scale. They are useful for characterizing grade distributions and identifying multiple populations within a data set. Appendix D contains a complete set of histograms and CDFs for copper and gold for the project area drawn by grade or mineralized shell and main rock type. The statistical properties of the copper and gold data are summarized in Tables 17-2 and 17-3 for OTS and Tables 17-4 and 17-5 for Hugo North.

CDF patterns show no distinct break for Southwest units except in the Bridge area. There and in the remaining OTS zones a noticeable bend in the distribution pattern occurs around 0.2% Cu. This is supportive of the choice of the 0.3% Cu threshold grade for these areas. Consistent copper mean values and coefficients of variation (CV) numbers occur in the Southwest Va and in Va inside the copper grade shell domains. Mean values range from 0.3 to 0.6, whereas CVs are low at 0.55 to 0.70. The mineralized copper domains all show about 7% to 15% included lower-grade material. Copper values in quartz monzodiorite units (Qmd) show variable differences in mean grade values with adjacent mineralized volcanic units. The differences depend on which intrusive phase was predominant in an area, e.g., early, altered and mineralized Central, South, and Wedge deposit Qmd units versus late, poorly altered and essentially unmineralized Southwest Qmd. Exception to the latter are the unique quartz-veined and mineralized phases (OT-Qmd and xQmd) in the Southwest gold zone. Coefficient of variation (CV) values range from low inside copper grade shells (0.45 to May 2005 [AMEC LOGO] PAGE 17-5 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 0.65) to over 1 in the Southwest and Central background areas. South and Wedge background Qmd show the lowest CV values (0.8 to 1.0). CDF plots commonly show double to triple lognormal distributions (in analyses ignoring grade shell boundaries). Usually one of the grade distributions is at very low values, accounting for 5% to 15% of the data. Another group represents about 30% to 70% of the remaining data. Threshold grades range from 0.15% to 0.30% Cu. These populations likely correspond to the three recognized intrusive Qmd phases in the Southern deposits. Occurrence of grade breaks in the grade trends support the use of grade shells in areas where mineralized Qmd units are present (Southwest - Bridge, Central, South, and Wedge). Gold grades are highest in the Southwest gold shell domain, where every lithology has been enriched. The mineralized basalt (Va) units contain the highest gold values here, averaging 1.5 g/t Au, followed by the OT-Qmd at 1.2 g/t Au. Background Va units in Southwest are still considered to be enriched, averaging 0.33 g/t Au. CV values are relatively low, ranging from 0.7 to 0.9. Elsewhere gold only occurs at elevated values in Central and South where defined by a gold grade shell. Va and Qmd units are similarly mineralized in these shells, averaging 0.4 to 0.7 g/t Au. CVs are low in Central (0.7 to 0.9) but high in South because of the occurrence of ubiquitous extreme values. Background Qmd in Southwest and Qmd and Va in Central and South contain quite low gold values (around 0.1 g/t) and corresponding high CVs. The Wedge deposit represents a gold-depleted area and contains the lowest average values (0.06 to 0.07 g/t) in the OTS. CDF diagrams for gold show typical positively skewed trends. For Southwest, the plots display single lognormal distribution populations in the high-gold shell and background Va. In the rest of the zones, double lognormal populations are shown with a variable but high included low-grade component. In plots ignoring grade shell boundaries, the Southwest Va units CDF patterns show a double lognormal population, with the threshold between the two populations at around 0.7 g/t Au (representing the 60th percentile). Similar trends are seen at Central and South but with a lower threshold grade between the two populations of between 0.3 and 0.5 g/t Au. Unlike the Southwest case, the threshold at Central and South occurs at a high percentile (95th). These observations lend support to the use of Gold grade shells at Southwest, Central, and South. HUGO NORTH DEPOSIT Copper grades in the mineralized units (Va, Ign, and Qmd) show single lognormal to near normal distributions inside each domain (Quartz Vein and 0.6%). CV values are quite low at 0.4. There is little variation due to lithological differences inside each domain, especially the quartz vein domain. Within the 0.6% shell, the mineralized Va contains slightly higher grades than associated ignimbrite and Qmd. The CDF pattern of copper data of all domains shows evidence for three populations: a higher-grade population (at a copper threshold value of 2.5%), a lower-grade zone (threshold value of 0.4% to 0.5% Cu), and a background lowest-grade domain. The pattern supports the construction of the Quartz Vein domain and 0.6% Cu shell. Gold grade distributions at Hugo North show typical positively skewed trends. The distributions are slightly more skewed than those for copper, but the level of skewness can still be described as only May 2005 [AMEC LOGO] PAGE 17-6 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA mild to moderate. Single lognormal populations are observed in each domain. Also, as in copper, little variation occurs between the lithological units inside the Main and West domains. CV values are low to moderate, varying from 0.7 to 1.0. Background populations are stable too, with CV values for Va and Qmd units averaging 0.8. The CDF pattern of all data between the background and Main domains shows evidence of two populations. The threshold value here is around 0.2 g/t Au and supports the drawing of the separate gold grade shells at Hugo North. 17.2.2 BOX-PLOT AND CONTACT PROFILE ANALYSES Two types of graphs, contact profiles and box-plots, help to visualize grade relationships at geological boundaries and the frequency distributions of the grades in the different geological units. Results guided the construction of the resource block model. Box-plots show the frequency distribution of the assay values by way of a graphical summary. The vertical axis of the plot gives the range of values for the particular assay (total copper). The box shows that portion of the sample data that falls between the 25th and 75th percentiles. In other words, the box captures the half of the data that fall in the middle of the distribution. The horizontal line that appears in the box represents the median of the data, or that value where half of the assays are greater and the remaining half are less than this median value. The mean or average of the data is shown with a dot. The vertical lines that extend away from the box reach to the minimum value toward the bottom of the plot and to the maximum value toward the top. Values for the statistics displayed by the box-plot are listed below each plot. Usually several boxes are plotted side by side so that the distributions can be compared. Box-plots were made for copper and gold to compare the grade distributions by domain in the OTS deposits and Hugo North. The side-by-side box-plots for these areas are shown in Appendix D. Contact profiles or plots were generated to explore the relationship between: 1) grade and lithology, and 2) grade and grade shell domains. The plots are constructed with software that searches for data with a given code, and then searches for data with another specified code and bins the grades according to the distance between the two points. This allows for a graphical representation of the grade trends away from a "contact." If average grades are reasonably similar near a boundary and then diverge as the distance from the contact increases, the particular boundary should probably not be used as a grade constraint. In fact, if a hard boundary is imposed where grades tend to change gradually, grades may be overestimated on one side of the boundary and underestimated on the opposite side. If there is a distinct difference in the averages across a boundary, there is evidence that the boundary may be important in constraining the grade estimation. Generated plots are also displayed in Appendix D. SOUTHERN OYU DEPOSITS Southwest deposit box-plots show similar to overlapping relationships for copper values in mineralized volcanic units (Va) from the south (Southwest - Far South) to the north (Southwest - Bridge). The mineralized Qmd units (OT - Qmd and the Qmd inside the Bridge Cu shell) also fall in May 2005 [AMEC LOGO] PAGE 17-7 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA the same range of values. The weakly to unmineralized Qmd shows markedly different lower-grade distributions. Gold distribution here reflects the presence of the Gold grade shell: highest value distributions lie in Va and OT-Qmd units within this shell. Anomalously high values are still present in most of the Va units outside the grade shell. Values are noticeable diminished towards the North (Southwest - Bridge) in both Va and Qmd units. Gold values in the main body of Qmd in this deposit mirror the quite low values in copper concentrations. Central deposit box-plots for copper and gold values show similar grade relationships among lithologic units inside and outside the respective grade shells. The same relationships are observed in South and Wedge deposits. The chalcocite blanket unit in Central contains similar copper distributions to the copper shell plots but is gold depleted, matching the outside gold shell distributions. Contact profiles for both metals in Southwest show distinct differences in grade in the vicinity of the boundary between Va and Qmd units. Distinct differences also occur across the gold shell. Central and South deposit plots show distinct differences in copper and gold values across the respective copper and gold grade shell boundaries. Little to no differences are observed in either gold or copper between the Va and Qmd units within each domain. Finally, in the Wedge deposit no differences were observed in copper grades between Qmd and mineralized volcanic units inside and outside the copper grade shell. Similarly, gold showed no distinct breaks across the copper grade shell boundary or between any lithology. HUGO NORTH DEPOSIT Copper box-plots for lithologies in the Quartz Vein domain show very similar distributions between the mineralized volcanic (mainly Va) and Qmd units. Comparisons between the 0.6% domain lithologies show somewhat more variability, but the box-plots still maintain an overlapping relationship between one another. Copper background results show a distinct difference in the copper grade distribution between the mineralized volcanics (mainly Ign) and Qmd. Gold results show similar to overlapping relationships among the lithologic domains in the Main gold zone. The West gold zone only contains Qmd and displays closeness to the same lithology in the Main gold zone. The gold background distributions show overlapping distributions between Va and Qmd. Both are quite distinct from background ign units, which display the lowest gold value distributions in Hugo North. Contact profiles for both metals show expected differences in grade across the grade and mineralized shells boundaries. The copper trend between the Quartz Vein and 0.6% domains is somewhat transitional within 30 m of the contact, becoming clearly distinct further away. Comparisons between lithology units within each domain show no grade differences between Va and Qmd units. Qmd and Ign units are rarely in contact with each other. Va and Ign copper relationships show small differences in the 0.6% domain. May 2005 [AMEC LOGO] PAGE 17-8 [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 17.2.3 GRADE SCATTER PLOTS Copper versus gold scatter plots were used to determine what degree of correlation exists between the two grades and if trends are evident. Various gold versus copper composite data scatter plots are shown in Appendix D. For OTS deposits, mineralization in Va units in and around the Southwest gold zone appear to define a Au-to-Cu ratio of 3:1. Further south, in the Southwest - Far South area, the Va units define a main 1:1 Au-to-Cu ratio and a subordinate 3:1 ratio. Elsewhere, the mineralized volcanic units of the South deposit show the marked depletion in gold relative to the Southwest area by defining an Au-to-Cu ratio of 1:10. A second set of gold mineralization is indicated on this scatter plot that appears to be related to a range of Cu grades (0.3% to 0.5% Cu) but not in any definable ratio. These data may represent the ubiquitous, narrow, high-grade vein population observed in the South deposit. At Central, the mineralization associated with Qmd phases generally outlines two Au-to-Cu ratio trends: a 1:10 ratio and a general 1.5 to 2:1 trend. At Hugo North the gold-to-copper relationships are poorer. Generally two trends may be present. The more common is a low gold trend that outlines an Au-to-Cu ratio of about 1:10 in the mineralized volcanic units. The Qmd unit also displays the 1:10 trend but also shows a more gold enriched one at about 1:2. 17.2.4 ESTIMATION DOMAINS SOUTHERN OYU DEPOSITS The data analyses demonstrated that all of the copper and gold grade shells in the Southern deposits should be treated as separate domains with respect to copper and gold. Additionally, the mineralized volcanic (Va) and Qmd units will be treated as separate sub-domains in Southwest for both copper and gold. Grades for blocks within the respective domains in each deposit or zone will be estimated with a hard boundary between them; only composites within the domain will be used to estimate blocks within the domain. Soft boundaries will be used between Qmd units and mineralized volcanic units in Central, South, and Wedge deposits. The various copper and gold grade shells for OTS deposits are shown in relation to each other and key structural features in Figures 17-1 and 17-2. HUGO NORTH DEPOSIT The data analysis showed that the mineralized and grade shells for copper and gold should be treated as separate domains with respect to grade interpolation. No distinctions were deemed necessary between inter-domain lithologic units. Some grade softening along the Quartz Vein domain and 0.6% Cu shell was implemented to reflect the transitional nature across that contact over 15 to 30 m. The various copper and gold grade shells for Hugo North deposits are shown in relation to each other and key structural features in Figures 17-3 and 17-4.

Generally, the distributions do not indicate a problem with extreme grades for copper. OTS coppers values did not receive a cap, whereas HN copper grades were given a high level one (99.5% level of the respective domain's grade distribution). For gold, capped grades were selected in domains with high CVs and/or where trends defined in the cumulative probability plots began to become discontinuous. In the latter case, this generally occurred between the 98% to 99.5% level. Cap grade values for the OTS deposits and Hugo North are shown in Table 18-1. The capped grades were applied to the assay data prior to compositing.

AMEC prefers to use a correlogram, rather than the traditional variogram, because it is less sensitive to outliers and is normalized to the variance of data used for a given lag. The correlogram ranges from -1 to +1, although models are usually made over the interval [0,1], where 0 represents no correlation (statistical independence) and 1 represents perfect correlation. Correlograms were calculated for copper and gold in the main mineralized domains in each zone. The approach to correlogram model development is to calculate a relatively large number of sample correlograms in several directions using composite values. Directional sample correlograms are calculated along horizontal azimuths of 0(degree), 30(degree), 60(degree), 90(degree), 120(degree), 150(degree), 180(degree), 210(degree), 240(degree), 270(degree), 300(degree), and 330(degree). For each azimuth, sample correlograms are also calculated at a dip of -30(degree) and -60(degree) in addition to horizontally. Finally, a correlogram is calculated in the vertical direction. Using the 37 sample correlograms, an algorithm determines the best-fit model. This model consists of a nugget effect; single or two-nested structure variance contributions; ranges for the variance contributions; and the model type (spherical or exponential type). After fitting the variance parameters, the algorithm then fits an ellipsoid to the ranges from the directional models for each structure. The anisotropy in grade variation is given by the two ellipsoids. Variogram model parameters and orientation data of rotated variogram axes are shown in Tables 17-7 and 17-8, respectively, for OTS and Tables 17-9 and 17-10, respectively, for Hugo North. The deposits of the Oyu Tolgoi project exhibit mineralization controls related to the intrusive history and structural geology (faults). The patterns of anisotropy demonstrated by the various correlograms tend to be consistent with geological interpretations -- particularly to any bounding structural features (faults and lithologic contacts) and quartz + sulphide vein orientation data. Key observations are described below. 17.4.1 SOUTHERN OYU DEPOSITS SOUTHWEST DEPOSIT Copper displays dominantly N-S trending, steeply E dipping, and S plunging long-ranged structures within the mineralized volcanics. Gold in the same lithology outside the gold shell displays shorter ranged structures that trend NNE-SSW, dipping moderately to the SE, and NE-SW, with moderate to steep SW dips. Gold within the gold shell contains similar ranges to the background data and shows NE-SW trending structures having moderate NW dips and steeply E dipping, SE-NW trending structures. In general, these observations match the structural data and gold shell shape. The latter has a near-vertical upper portion and a moderately south plunging lower half. Mineralizing fluids are thought to have used the steeply west dipping East Bounding Fault as a conduit. Fluid flow would likely have been upwards and "away" from the fault plane, that is, in a northwesterly direction. This May 2005 PAGE 17-13 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA would account for the southeast dip directions. The north to northeast trends match attitudes of the bounding faults and observed vein data. SOUTH DEPOSIT Copper is influenced by the geometry of the deposit defined in part by the flanking faults (South and Solongo). Two strong structures are defined: a near cylindrical, moderately NE plunging structure and a NNW-SSE trending, moderately SW dipping structure. Gold displays similar NNW-SSE trending structures that have more gentle westerly dips. WEDGE DEPOSIT Copper structures show pronounced NE-SW trends with dips varying from moderately to steeply SE. Overall attitude is consistent with the contact orientation between the ignimbrite and overlying unmineralized sedimentary+volcanic sequence. CENTRAL DEPOSIT Copper structures show a main short-ranged steeply S dipping E-W trending orientation and a lesser longer ranged, NE-SW trending shallow dipping attitude. The latter structure outlines a tabular shape, mimicking the copper grade shell shape. Gold outlines two sets of short-ranged structures: a NW-SE trending, steeply NE dipping structure, and a NE-SW trending, shallow dipping tabular structure. The nugget effects, or random variation components of spatial variation, tend to be moderate in all OTS deposits. Copper variograms generally have nugget effects of 25% to 35% of the total variation, whereas gold variograms have somewhat more variable nugget effects of 20% to 50% of the total variation. 17.4.2 HUGO NORTH DEPOSIT Copper displays moderate to long ranges in the Quartz Vein and 0.6% domains. The former displays NNE-SSW trending, moderate to steep ESE dipping structures, effectively mimicking the mineralized shell and the surrounding structures (West Bat and East Hugo faults). The 0.6% domain shows two sets of structures: a NE-SW trending, gently E dipping set and a NNW-SSE trending, moderately NE dipping set. Again, the structures mirror the shape of the grade shell. Background data for copper were too sparse to obtain any meaningful correlograms. The 0.6% model was used instead. Gold structures are rather simple in the Main gold zone: N-S trending, steeply E dipping. The West gold zone had too few data; the Main gold variogram model was used instead. Gold in the background gave an single structure, long-ranged set that was similar to the Main gold zone: N-S May 2005 PAGE 17-14 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA trending and steep E dips. These structures for gold are distinct from those of copper, and imply a different mineralizing fluid path for gold The nugget effects are low to moderate at Hugo North. Copper variograms have nugget effects of 25% to 30% of the total variation, whereas gold variograms have variable nugget effects that range from 20% to 35% of the total variation.

September 2004 PAGE 17-18 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 17.5 MODEL SETUP The block size for the OTS model was selected based on mining selectivity considerations (open pit mining). It was assumed the smallest block size that could be selectively mined as ore or waste, referred to the selective mining unit (SMU), was approximately 20 m x 20 m x 15 m. In this case the SMU grade-tonnage curves predicted by the restricted estimation process adequately represented the likely actual grade-tonnage distribution. For Hugo North, mining selectivity was less of an issue because the mining method envisioned, block cave mining, does not easily yield to any selectivity. The same block was used for ease of integrating the block models for mine planning considerations. The assays were composited into 5 m down-hole composites in the OTS and 15 m down-hole in HN. The different lengths mirror the proposed mining method in each area. The compositing honoured the lithology domain zone by breaking the composites on the domain code values. The composites included any post-mineral dyke material intervals that were deemed too small to be part of a post-mineral dyke geology model. The capping limits were applied to the assay data prior to compositing. Also, assay data in older drill holes (pre-OTD231) were adjusted for bias (Juras 2003, Hodgson 2004). The composite data were back-tagged by the grade and mineralized shells (on a majority code basis). AMEC reviewed the compositing process and subsequent back-tagging, and found all performed as expected. Bulk density data were assigned to a unique MineSight(R) assay database file. These data were composited into 15 m fixed-length down-hole values in both areas. Various coding was done on the block models in preparation for grade interpolation. The block model was coded according to zone, lithologic domain, and grade shell. Percent below topography was also calculated into the model blocks. Post-mineral dykes were assumed to represent zero grade waste cutting the mineralized rock. The shapes were used to calculate an ore-remaining percent for each block by subtracting the volume percent dyke that intersects a block from 100. This percentage was used in the resource tabulation procedure to properly account for mineralized material and to account for internal or non-separable dilution. Only the hypogene mineralization was estimated (with the Central chalcocite blanket being the only exception). The base of sulphide oxidation surface defined the top of the hypogene mineralization in the OTS deposits. 17.6 ESTIMATION The Oyu Tolgoi estimation plans, or sets of parameters used for estimating blocks, were designed using a philosophy of restricting the number of samples for local estimation. AMEC has found this to be an effective method of reducing smoothing and producing estimates that match the Discrete Gaussian change-of-support model and ultimately the actual recovered May 2005 PAGE 17-19 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA grade-tonnage distributions. While local predictions based on the small number of samples are uncertain(1), this method can produce reliable estimates of the recovered tonnage and grade over the entire deposit, i.e., the global grade-tonnage curves from the estimations are accurate predictors of the actual grade-tonnage curves. Modelling consisted of grade interpolation by ordinary kriging (KG). The chalcocite blanket in Central was interpolated by grade averaging because of the small data population in this domain. Only capped grades were interpolated. Nearest-neighbour (NN) grades were also interpolated for validation purposes. Blocks and composites were matched on estimation domain. To reduce the impact of locally inaccurate block grades due to conditional bias at the grade shell boundaries, all blocks straddling those contacts were estimated twice with each of the composite sets on either side of the contact. The final block grade was calculated with a volume-weighted average of the two domain grades in that block. The effect is to slightly smooth the grades at the hard grade shell boundary so that the distribution of block grades more closely approximates the shape of the composite distribution. The search ellipsoids were oriented preferentially to the orientation of the respective zone as defined by bounding structures or to the attitude of the relevant copper or gold grade shell. Search ranges for OTS deposits were 175 m to 250 m along the respective long axis, 125 m to 175 m down the dip direction, and 150 m to 200 m vertically. For Hugo North the ranges for the Quartz Vein Domain (Cu) and all gold domains consisted of 300 m along the long axis, 125 m down the dip direction, and 200 m vertically. The remaining copper domains were 300 m to 400 m along the long axis, 225 m to 270 m down the dip direction, and 125 m to 150 m vertically. Block discretization was 4 x 4 x 3. A two-pass approach was instituted for interpolation. The first pass allowed a single hole to place a grade estimate in a block, and the second pass required a minimum of two holes from the same estimation domain. This approach was used to enable most blocks to receive a grade estimate within the domains, including the background domains. Blocks received a minimum of 5 and maximum of 4 composites from a single drill hole (for the two-hole minimum pass) in the OTS model. Maximum composite limit was 20. For Hugo North, a minimum of 4 and maximum of 10 composites were used, with a limit of 3 composites from a single drill (smaller-numbered composites reflect the larger composite size at HN). These parameters were based on the geological interpretation, data analyses, and variogram analyses. The number of composites used in estimating grade into a model block followed a strategy that matched composite values and model blocks sharing the same ore code or domain. The minimum and maximum number of composites were adjusted to incorporate an appropriate --------- (1) Local grade estimates at the block-scale can be conditionally biased. Blocks estimated to be low-grade will actually be higher grade and vice versa. Division of the deposits into domains prior to estimation reduces the impact of conditional bias.

This was done by change-of-support analysis (Discrete Gaussian or Hermitian polynomial change-of-support method), as described below. For both metals, an outlier restriction was used to control the effects of high-grade composites within each of the domains in OTS and HN, particularly in background domains and poorly mineralized units (e. g, Southwest Qmd). The threshold grades were generally set as the grade of the relevant grade shell, or the distinct break in the CDF curves in the case of poorly mineralized units. In Southwest (OTS), an outlier of 1.0 g/t Au was used in background domains for Va and Qmd. Other OTS gold outlier cases were 1.5 g/t implemented within the South gold shell (to minimize grade "blow-outs" from extreme grade composites at depth) and 0.5 g/t within the Wedge. OTS zones that contained copper grade shells had a 0.5% Cu outlier value implemented in the background domains, except for the South deposit, where it was set to 0.8%. Hugo North outlier values were 3% Cu within the 0.6% domain and 1% Cu in the copper background domain. Gold values were restricted to 3 g/t in the West gold zone and to 0.3 g/t in the gold background domain. The restricted distances were 40 m in OTS and 50 m in HN. Bulk density values were estimated into the resource model by an averaging of composites. A maximum of six and minimum of two 15 m composites were used for the averaging. A rectangular search was used, measuring 200 m north x 200 m east x 50 m elevation. The assignment was constrained by matching composite values and model blocks that shared the same lithology domain in both the OTS and HN models. In the event a block was not estimated, default density values were assigned based on lithology code. Final resource grade values were adjusted to reflect likely occurrences of internal dilution from the unmineralized post-mineral dykes. The estimated mined resources for Hugo North and Southern Oyu deposits were tabulated and reported using these adjusted or diluted grade values. The planned mining method for Hugo North, underground block caving, allows for virtually no segregation of diluting material. Therefore at Hugo North, model blocks that contained less than 85% and greater than 15% mineralized material or ore by volume had final block grades recalculated with volume-weighted averaging of the interpolated grade and dyke grade (taken as zero) to 100% ore. Blocks containing more than 85% ore were allowed to use the existing interpolated grades. For block with less than 15% ore by volume, the blocks were reset to 100% but at zero grade values. The Southern Oyu deposits will be mined by open-pit methods. This allows for potential segregation of unmineralized dyke material. However, contact dilution and ore loss will be inevitable during mining. For this reason, contact block grades and ore percent values were also adjusted. Model-blocks containing greater than 85% mineralized material or ore by volume, were reset to 100% ore, but the interpolated grades were adjusted by a volume-weighted averaging of the interpolated grade and dyke grade (taken as zero). Model blocks containing less than 15% ore by volume were reset to 0% ore and zero grade values. Blocks containing less than 85% and greater than 15% ore by volume retained the interpolated grade value. However, in this case, the ore percent values were adjusted downward by 15%. May 2005 PAGE 17-21 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA 17.6.1 VALIDATION VISUAL INSPECTION AMEC completed a detailed visual validation of the OTS and HN resource models. Models were checked for proper coding of drill hole intervals and block model cells, in both section and plan. Coding was found to be properly done. Grade interpolation was examined relative to drill hole composite values by inspecting sections and plans. The checks showed good agreement between drill hole composite values and model cell values. The hard boundaries between grade shells appear to have constrained grades to their respective estimation domains. The addition of the outlier restriction values succeeded in minimizing grade smearing in regions of sparse data and, in general, all background domains. Examples of representative sections and plans containing block model grades, drill hole composite values, and domain outlines are included in Appendix F for the OTS deposits and Appendix G for the Hugo North deposit. MODEL CHECK FOR CHANGE-OF-SUPPORT An independent check on the smoothing in the estimates was made using the Discrete Gaussian or Hermitian polynominal change-of-support method described by Journel and Huijbregts (Mining Geostatistics, Academic Press, 1978). The distribution of hypothetical block grades derived by this method is compared to the estimated model grade distribution by means of grade-tonnage curves. The grade-tonnage curves allow comparison of the histograms of the two grade distributions in a format familiar to mining. If the estimation procedure has adequately predicted grades for the selected block size, then the grade-tonnage curves should match fairly closely. If the curves diverge significantly, then there is a problem with the estimated resource. This method uses the "declustered" distribution of composite grades from a nearest-neighbour or polygonal model to predict the distribution of grades in blocks. In this case the blocks used in the model are 20 m x 20 m x 15 m. The unadjusted polygonal model assumes much more selectivity for ore and waste than is actually possible in mining practice, since many sample-sized volumes are averaged together within a block. This means that part of the sample-sized volumes in the block may be ore (above the mining cutoff) and part may be waste. Hence, the distribution of the grade of the blocks is not likely to resemble the distribution of grades from composite samples derived from the polygonal estimate. The method assumes that the distribution of the blocks will become more symmetric as the variance of the block distribution is reduced, i.e., as the mining blocks become bigger. The histogram for the blocks is derived from two calculations: - the block-to-block variance (sometimes referred to in statistics as the between-block variance), which is calculated by subtracting the average value of the variogram within a block from the variance for composite samples (the sill of the variogram) May 2005 PAGE 17-22 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA - the frequency distribution for the composite grades transformed by means of hermite polynomials (Herco: hermite correction) into a less skewed distribution with the same mean as the declustered grade distribution and with the block-to-block variance of the grades. The distribution of hypothetical block grades derived by the Herco method is then compared to the estimated grade distribution to be validated by means of grade-tonnage curves. The distribution of calculated 20 m x 20 m x 15 m block grades for copper in the main OTS domains of Southwest, Central (Cu Shell), South (Cu Shell), and Wedge (Cu Shell), and the HN Quartz Vein and 0.6% domains are shown with dashed lines on the grade-tonnage curves in Appendix E. This is the distribution of grades based on 20 m blocks obtained from the change-of-support models. The continuous lines in the figures show the grade-tonnage distribution obtained from the block estimates. The grade-tonnage predictions produced for the model show that grade and tonnage estimates are validated by the change-of-support calculations over the likely range of mining grade cutoff values (equivalent to about 0.4% to 0.6% Cu). MODEL CHECKS FOR BIAS AMEC checked the block model estimates for global bias by comparing the average metal grades (with no cutoff) from the model (KG) with means from nearest-neighbour estimates. (The nearest-neighbour estimator declusters the data and produces a theoretically unbiased estimate of the average value when no cutoff grade is imposed and is a good basis for checking the performance of different estimation methods.) Results, summarized in Table 17-11, show no problems with global bias in the estimates. AMEC also checked for local trends in the grade estimates (grade slice or swath checks). This was done by plotting the mean values from the nearest-neighbour estimate versus the kriged results for benches (in 30 m swaths) and for northings and eastings (both in 40 m swaths). The kriged estimate should be smoother than the nearest-neighbour estimate, thus the nearest-neighbour estimate should fluctuate around the kriged estimate on the plots. Results for copper and gold for OTS and HN domains are shown in Appendix E. The two trends behave as predicted and show no significant trends of copper or gold in the estimates in both OTS and HN models. HISTOGRAMS AND PROBABILITY PLOTS Histograms were constructed to show the frequency of sample grades within the mineralized domains. Both kriged and nearest-neighbour plots were made for copper and gold. The nearest-neighbour plots mimic the respective composite value distribution. The kriged results show the formation of a more symmetric distribution because of the smoothing effect caused by using multiple values from multiple drill holes to interpolate a model block value.

The mineralization of the project satisfies sufficient criteria to be classified into Measured, Indicated, and Inferred mineral resource categories. 17.7.1 MEASURED MINERAL RESOURCES Inspection of the model and drill hole data on plans and sections in the Southwest deposit (Southern Oyu area) centred around the gold shell, combined with spatial statistical work and investigation of confidence limits in predicting planned quarterly production, showed good geologic and grade continuity in areas where sample spacing was about 50 m. When taken May 2005 PAGE 17-24 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA together with all observed factors, AMEC decided that blocks covered by this data spacing in the Southwest deposit may be classified as Measured Mineral Resource. A three-hole rule was used, where blocks containing an estimate resulting from three or more samples from different holes (all within 55 m and at least one within 30 m) were classified as Measured Mineral Resource. 17.7.2 INDICATED MINERAL RESOURCES The Indicated Mineral Resource category is supported by the present drilling grid over most of the remaining part of the Southern Oyu deposits. The drill spacing is at a nominal 70 m on and between sections. Geologic and grade continuity is demonstrated by inspection of the model and drill hole data in plans and sections over the various zones, combined with spatial statistical work and investigation of confidence limits in predicting planned annual production. Considering these factors, AMEC decided that blocks covered by this data spacing may be classified as Indicated Mineral Resource. A two-hole rule was used, where blocks contained an estimate resulting from two or more samples from different holes. For the Southwest deposit the two holes needed to be within 75 m, with at least one hole within 55 m. For the remaining deposits, both holes needed to be within 65 m, with at least one hole within 45 m, to be classified as Indicated Mineral Resource. The Indicated Mineral Resource category is supported at Hugo North where the drill spacing is approximately 125 m x 75 m centres. Geologic and grade continuity is demonstrated by inspection of the model and drill hole data in plans and sections over the various zones, combined with spatial statistical work and investigation of confidence limits in predicting planned annual production. Considering these factors, AMEC decided that blocks covered by this data spacing may be classified as Indicated Mineral Resource. To help define the area outlined by this drill spacing, AMEC utilized an indicator variogram method (based on the Quartz Vein domain) where a suitable threshold value was selected by inspection relative to the observed drill hole locations. 17.7.3 INFERRED MINERAL RESOURCES All interpolated blocks that did not meet the criteria for either Measured or Indicated Mineral Resource at OTS or HN were assigned as Inferred Mineral Resource if they fell within 150 m of a drill hole composite. 17.8 MINERAL RESOURCE SUMMARY The mineralization of the Oyu Tolgoi Project as of 3 May 2005 is classified as Measured, Indicated, and Inferred mineral resources. The total project mineral resources are shown in Table 17-12 and are reported at a copper equivalent cutoff grade of above 0.6%. The mineral resource summary for the Southern Oyu deposits are reported in two ways in this report. The May 2005 PAGE 17-25 [AMEC LOGO] [IVANHOE MINES LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA first, in Table 17-12, quotes the Southern Oyu resources as global resources above cutoff grades, without the constraint of an open pit or underground mining shape, and is consistent with previous disclosed resource estimates. The second tabulation, in Table 17-13, is done as a guide to the reasonableness of future open pit mining operations. Here the Measured and Indicated mineral resources have been recast using an ultimate life-of-mine open pit shell (at 0.3% Cu Eq. and using US$1.00 for copper and US$400/oz for gold) designed by Minproc Limited of Australia. Hugo North mineral resources are shown in Table 17-14 and are reported at above various copper equivalent cutoff grades. Hugo South mineral resources are included here for completeness. Though not re-estimated as part of this work, a revised definition of the separation of Hugo South and Hugo North along the north-dipping 110 fault necessitated a re-tabulation of the existing Hugo South model. The result, in Table 17-14, shows slight variations since the last disclosure in November 2003. The equivalent grade was calculated using assumed metal prices of US$0.80/lb for copper and US$350/oz for gold. For convenience the formula is: CuEq = %Cu + (g/t Au*11.25)/17.64 The contained gold and copper estimates in the tables below have not been adjusted for metallurgical recoveries.

May 2005 PAGE 19-1 [AMEC LOGO] [IVANHOE MINES NEW HORIZONS LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA SECTION 20 - CONCLUSIONS AND RECOMMENDATIONS AMEC reviewed pertinent data from the Oyu Tolgoi project to obtain a sufficient level of understanding to assess the Mineral Resource estimate for the Southern Oyu deposits (Southwest, South, Central, Wedge) and the Hugo North deposit. AMEC's general conclusions from this review are as follows: The geology of the Oyu Tolgoi project is well understood. The deposits are considered to be examples of a copper-gold porphyry system and related high-sulphidation types of deposits. The deposits are grouped into two areas: Southern Oyu and Hugo Dummett. The exploration program relies strongly on geophysical survey data (IP and magnetics), and other target anomalies still remain within the project land holdings. SOUTHERN OYU Four deposits are known in the Southern Oyu system: - The Southwest deposit consists primarily of pyrite-chalcopyrite mineralization related to biotite-magnetite alteration, overprinted by chlorite-sericite alteration. Mineralization is characterized by high gold contents with Au:Cu ratios of about 1:1 in the main part of the deposit, rising to 3:1 in the core of the system and at depth. Gold in the Southwest Oyu deposit is closely associated with chalcopyrite and occurs intergrown with chalcopyrite, as inclusions and fracture infills within pyrite, or on grain boundaries of pyrite. The deposit is essentially hosted in augite basalts. - South deposit mineralization is hosted in quartz monzodiorite in the southwest and basalt throughout the central portion of the deposits. Chalcopyrite is the principal copper sulphide, but in higher-grade areas bornite locally exceeds chalcopyrite. Alteration in basaltic rocks consists of chlorite, biotite, hematite / magnetite, and weak sericite. Quartz monzodiorite contains advance argillic alteration. Small zones with elevated gold values occur locally. - Mineralization in the Central deposit is characterized by an upward-flaring high-sulphidation zone that overprints and overlies porphyry-style chalcopyrite-gold mineralization. A secondary enriched supergene chalcocite blanket tens of metres in thickness overlies the high-sulphidation covellite-pyrite zone. The high-sulphidation portion of the Central Oyu deposit contains a mineral assemblage of pyrite, covellite, chalcocite/digenite, enargite, tennantite, cubanite, chalcopyrite, and molybdenite. Dominant host rocks are dacite tuff and quartz monzodiorite. Higher-grade mineralization is associated with disseminated and coarse-grained fracture-filling sulphides in zones of intensely contorted quartz stockwork veins and anastamosing zones of hydrothermal breccias. Chalcopyrite-gold mineralization is dominant on the south and western margins of Central within either basalt or quartz monzodiorite adjacent to intrusive contacts with basalt. The high-sulphidation part of the Central deposit lacks significant gold. Alteration in the Central deposit shows a close spatial May 2005 PAGE 20-1 [AMEC LOGO] [IVANHOE MINES NEW HORIZONS LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA relationship to mineralization and original host lithology. Biotite-chlorite and intermediate argillic alteration coincide with chalcopyrite-gold mineralization within basalt. Advanced argillic and sericite alteration coincide with the high-sulphidation mineralization within quartz monzodiorite and ignimbrite. - The Wedge deposit contains a zone of high sulphidation mineralization hosted principally in dacite tuff, grading downward and southward into chalcopyrite mineralization in basalt and quartz monzodiorite host rocks. High-sulphidation mineralization consists of pyrite, chalcopyrite, bornite, enargite, covellite, and primary chalcocite in advanced argillically altered host rocks. The high-sulphidation mineralization grades downward into chalcopyrite, with lesser bornite within basalt host rocks, and pyrite + chalcopyrite mineralization in quartz monzodiorite. Gold is absent, except locally in drill holes adjacent to the South Fault. HUGO NORTH - The highest-grade copper mineralization in the Hugo North deposit is related to a zone of intense stockwork to sheeted quartz veins. The high-grade zone is centred on thin, east-dipping quartz monzodiorite intrusions or within the upper part of the large quartz monzodiorite body and extends into the adjacent basalt. In addition, moderate- to high-grade copper and gold values occur within quartz monzodiorite below and to the west of the intense vein zone, in the Hugo North gold zone. This zone is distinct in its high gold (ppm) to Cu (%) ratios (0.5:1). Bornite is dominant in the highest-grade parts of the deposit (3% to 5% Cu), and is zoned outward to chalcopyrite (2%). At grades of <1% Cu, pyrite-chalcopyrite +/- enargite, tennantite, bornite, chalcocite, and rarely covellite occur, hosted mainly by advanced argillically altered dacite tuff. - Elevated gold grades in the Hugo North deposit occur within the up-dip (western) portion of the intensely veined high-grade core, and within a steeply dipping lower zone cutting through the western part of the quartz monzodiorite. Quartz monzodiorite in the lower zone exhibits a characteristic pink to buff colour, with a moderate intensity of quartz veining (25% by volume). This zone is characterized by finely disseminated bornite and chalcopyrite, although in hand specimen the chalcopyrite is usually not visible. The sulphides are disseminated throughout the rock in the matrix as well as in quartz veins. The fine-grained sulphide gives the rocks a black "sooty" appearance. The red colouration is attributed to fine hematite dusting, mainly associated with albite. - The Hugo North deposit is characterized by copper-gold porphyry and related styles of alteration similar to those at Hugo South. This includes biotite-K-feldspar (K-silicate), magnetite, chlorite-muscovite-illite, albite, chlorite-illite-hematite-kaolinite (intermediate argillic), quartz-alunite-pyrophyllite-kaolinite-diaspore-zunyite-topaz-dickite (advanced argillic), and sericite/muscovite zones. May 2005 PAGE 20-2 [AMEC LOGO] [IVANHOE MINES NEW HORIZONS LOGO] HUGO DUMMETT AND SOUTHERN OYU DEPOSITS TECHNICAL REPORT OYU TOLGOI, MONGOLIA RESOURCE ESTIMATION - The database used to estimate the mineral resources for the Oyu Tolgoi project consists of samples and geological information from 583 core drill holes in the Southern Oyu deposits and 156 drill holes, including daughter holes, in Hugo North. The holes were drilled by Ivanhoe between 2002 and April 2005. Data transfer to the resource database was validated from original assay certificates through a 5% check of the database. - Ivanhoe employs a comprehensive QA/QC program. Each sample batch of 20 samples contains four or five quality control samples. The quality control samples consist of one duplicate split core sample and one uncrushed field blank, which are inserted prior to sample preparation; a reject or pulp preparation duplicate, which is inserted during sample preparation; and one or two reference material samples (one <2% Cu and one >2% Cu if higher-grade mineralization is present based on visually estimates), which are inserted after sample preparation. AMEC reviewed Ivanhoe's QA/QC procedures at site and found them to be strictly adhered to. Duplicate performance of core, coarse reject, and pulp duplicates was evaluated by AMEC and found to be well within the respective accepted ranges. The current Ivanhoe QA/QC program exceeds industry standards and demonstrates that the assay process for the Southern deposits samples is in control. - The Oyu Tolgoi resource models were developed using industry-accepted methods. AMEC validated the model estimates and found them to reasonably estimate grade and tonnage for the Southern deposits. The mineral resources of the Oyu Tolgoi project were classified using logic consistent with the CIM definitions referred to in National Instrument 43-101. The mineralization of the project satisfies sufficient criteria to be classified into Measured, Indicated and Inferred mineral resource categories. This independent mineral resource estimate and review by AMEC supports the May 2005 Oyu Tolgoi project mineral resource statement.
