(IMR-TSX.V) is pleased to announce a progress report on assays received from the bonanza grade feeder structures and structurally controlled breccias at Navidad Hill (one zone within the 5.8 kilometre overall Navidad system). The strike length of bonanza grade structures has been extended by over 50% to a current total of 636 metres (from 402 metres previously announced), with a length weighted average of 162 ounces per ton (oz/t) silver (5,546 g/t), 3.8% copper and 9.8% lead. Individual samples of bonanza grade silver-copper-lead mineralization have returned remarkable values of up to 1,475 oz/t (50,520 g/t) silver. The 70 kilometre IP/Resistivity survey is nearing completion and preliminary results show an excellent correlation between mapped mineralization and chargeability; in addition, significant anomalies have been delineated under cover. Additional detailed sampling of replacement style mineralization (Previously reported exposed over several kilometers with an average grade of 4.61 oz/t [158 g/t] silver and 8.9% lead) is complete and results will be released when they are received in full. Results from ongoing gravity, magnetic, and IP/Resistivity geophysical work will be released as they are received and evaluated by IMA Geologists. The Navidad discovery is without precedent in Patagonia and represents an exciting new style of mineralization for the region. A close geologic analogue for Navidad is the Eskay Creek Mine in British Columbia. Navidad is very well located and is less than 1 km from a provincial gravel highway, 45 km from the nearest town, 45 km from major high-voltage power lines, 190 km from a railway line, and 340 km from a deep-sea port. Please refer to the Detailed Technical Summary in the appendix of this news release or IMA's web site (www.imaexploration.com) for more detailed results. IMA Exploration Inc. has a strong treasury to fund its exploration objectives. The Company focuses on quality exploration work designed to define economic gold and silver deposits in Argentina and Peru. IMA has put together an enviable property portfolio including over 37 well-located, high-potential projects and is continuing to add to this package through grass-roots exploration and staking.

APPENDIX - Detailed Technical Summary Mineralization at Navidad Hill consists of bonanza-grade feeder structures hosted by felsic flow dome rocks (often with peripheral calcite-barite veins), structures within carapace breccia that mantles the flow dome, and mineralized carapace breccias. These mineralization styles have now been mapped over an area 475 metres long by 60 to 140 metres wide. Within this area, 636 cumulative metres of structurally-controlled, bonanza-grade mineralization has been mapped, as has 537 metres of calcite-barite veins. In addition, interpretation of mapping suggests carapace breccia-hosted mineralization is the predominant rock type in three areas of 50 by 150 metres, 18 by 20 metres, and 20 by 25 metres, respectively. A total of 259 rock samples have been collected of which 242 are continuous chip samples. The following Table 1 summarizes results of the rock chip sampling.

Structurally-controlled mineralization within the breccia suggests that the flow dome containing bonanza-grade structures may be locally present beneath this unit. At the southeast end of the Navidad Hill Mineralized Zone, mineralization and flow dome is overlain by a thin layer of post-mineralization volcanic tuff. Soil sample results and a few isolated rock samples suggest that bonanza-grade mineralization and flow dome may extend further to the southeast beneath this tuff. Widths of the mapped bonanza-grade structures are variable, ranging from less than one metre to 3.3 metres. An average width cannot yet be determined due to soil cover that often obscures the contacts. Table 2 shows individual and composite assays from select examples of wider intersections. Mapping used to constrain the calculations of average grades presented here was done at 1:500 scale, or greater detail, using surveyed grid pickets spaced at 20 metre intervals, and tape measures to obtain the best possible accuracy. The width of each sampled interval was measured and recorded in the field. Length weighted average grades were calculated by taking the sum of the length of each sample multiplied by its grade divided by the sum of the lengths. Gaps between samples due to soil cover were conservatively included assuming the length of the gap has zero grade. This was done for each mineralization style within each of eight domains defined on the basis of host lithology and mineralization types present. Average grades of each mineralization style were then calculated for the entire area. A listing of selected samples and sample composites is shown in Table 2 and a complete listing of the summary data for all 242 continuous chip samples taken from the Navidad Hill area is shown in Table 1.

Table 3 shows the effects of applying cutting factors of 15,000 g/t silver and 11,000 g/t silver (90th percentile and two standard deviations, respectively) to be minimal. A comprehensive check assay program has been undertaken since the discovery of Navidad. ALS Chemex is the primary laboratory and receives, prepares and assays all the samples. Randomly selected samples are sent to Alex Stewart (Assayers) Argentina S. A. who acts as the secondary laboratory. At the time of writing 70 check samples (approximately 12% of all samples) have been analyzed by both laboratories. Data for these 70 samples for silver, copper and lead have been systematically analyzed and there is excellent correlation between the two laboratories for all samples with the exception of one low-grade silver sample which is under further review.
