(IMR-TSX.V, IMXPF-OTC.BB) is pleased to provide an exploration update for its 100% owned Navidad silver-lead discovery located in Patagonia, Argentina. To date, IMA has defined an Indicated Resource of 268 million ounces of silver and 1.1 million tonnes of lead (80.8 million tonnes at 103 g/t silver and 1.45% lead using a 50 g/t silver equivalent cut-off) at the Navidad Project, quickly making it one of the world's largest primary silver deposits. Dr. Paul Lhotka, P.Geo., IMA's Qualified Person at the Navidad Project, and Keith Patterson, M.Sc., P.Geo., IMA's Exploration Manager, have overseen the completion of 27,981m of core drilling in 174 holes taking the Navidad Project from an undrilled prospect to one of the world's largest silver resources. Exploration drilling continues to expand the mineralization at Calcite Hill while detailed surface exploration is outlining new zones along the Argenta Trend. Shareholders can look forward to continued exploration drilling that will test these new targets and quantify the potential additional value at the project. In April of 2005, our exploration team commenced an additional 10,000 metre drill program as part of Phase III drilling that continues to target expansions to the Calcite Hill zone. The first set of results from this round of drilling is expected within weeks. Concurrent with the drill program a new resource calculation is underway on Calcite Hill with the results also expected within weeks. Calcite Hill has now been defined by drilling over a strike length of 500m and varies in horizontal width from approximately 50 to 150 metres and vertical thickness from 10 to 110 metres. The new resource calculation is expected to add significantly to the overall size of the known Navidad deposits. Within the known deposits at Navidad, silver represents approximately 62% of the gross metal value while lead accounts for approximately 38% at current metal prices. [Assuming silver and lead account for 100% of the gross metal value. Metal prices used in this calculation were silver = $7.22 per ounce and lead = $0.45 per pound.] The outlook for both metals is strong, yet despite a rapidly rising price and demand for lead, this market remains poorly understood by the broader investment community. Over the last two years the price of lead has doubled. This is very significant to IMA shareholders because while Navidad is a primary silver discovery, it contains a substantial lead value that continues to grow. Recent surface work along the Argenta trend (parallel to the Navidad trend) has discovered high-grade lead values over significant widths. New discoveries include the "Bajo del Plomo", "Filo del Plomo" and "Ginger" zones where lead values of up to 10.7% lead over 10 metres, 7.3% lead over 17 metres and 4.8% lead over 21 metres respectively, have been discovered. These new discoveries are located southeast of the previously announced Loma de la Plata zone, along the 8 kilometre Argenta mineralized trend (see map at http://www.imaexploration.com/i/maps/imr-jun012005-map.gif ). With the addition of the three new zones, the Argenta Trend now consists of five named mineralized zones along an 8 kilometre strike length. Mineralization styles vary from silver-copper rich at the northwest end at Sector Zeta, to silver-rich at Loma de la Plata, to lead-dominant at Bajo del Plomo, Filo del Plomo and Ginger. Mineralization is hosted by the same trachyandesitic volcanic rocks as the Galena, Navidad, and Calcite Hill deposits, and in some cases in adjacent sedimentary rocks. It appears to occur at approximately the same stratigraphic position as the known ressources but with significant differences in sedimentary facies. NEWS RELEASE JUNE 1, 2005 IMA EXPLORATION INC. PAGE 2 -------------------------------------------------------------------------------- At Bajo del Plomo, 35 measured chip samples have been collected, of which 30 make up chip sample lines 1, 3, 4, 5, and 6. Individual samples range from below detection to 700 g/t silver and 0.01% to 20.3% lead. Length weighted average grades from the chip sample lines include 273 g/t silver and 10.7% lead over 10.0m, complete results are presented below. It is worth noting that lines 3 and 4 include 7.0 and 23.8m of unsampled, soil-covered gaps that were included in the average grade calculations at zero grade, thereby reducing the overall grade significantly. Bajo del Plomo is located immediately to the southeast of Loma de la Plata. Filo del Plomo is located approximately 1km to the southeast of Loma de la Plata and includes results such as 17.15m of 71 g/t silver and 7.27% lead and 23.50m of 60 g/t silver and 4.38% lead. 83 measured chip samples have been collected at Filo del Plomo and range from below detection to 340 g/t silver and 0.06% to 29.7% lead. Chip sample lines cover a strike length of 560m and vary from 3.0 to 23.5m in width. The Ginger zone is located 2.1 km to the southeast Filo del Plomo and 32 samples have been collected from 3 chip lines in addition to several dozen individual chip samples. Results from this sampling include 21.2m of 30 g/t silver and 4.84% lead from line G1 and 15.2m of 21 g/t silver and 4.63% lead from line G2. A large expansion to the pole-dipole induced polarization (IP) and magnetic geophysical surveys has recently been completed at the Navidad project. The company now has over 58 square kilometres of geophysical surveying covering and extending beyond the Navidad and Argenta Trends. This is a major increase from the 17.5 square kilometre area that was previously surveyed. The Galena Hill Deposit has a strong geophysical signature, while other deposits such as Navidad and Calcite Hills have much more subtle signatures. This additional geophysical coverage provides a wealth of information about the geology and structure at Navidad in addition to highlighting new areas prospective for mineralized zones that may be completely buried. The Company maintains a rigorous quality-control and quality-assurance program, a copy of which is available at IMA's website www.imaexploration.com . Dr. Paul Lhotka is IMA's "Qualified Person" at the Navidad project and has overseen all aspects of the current program. IMA's Annual General Meeting will take place at 12:30pm, June 23, 2005, in the Garibaldi Room at the Four Seasons Hotel, 791 West Georgia Street, Vancouver, B.C.
