(IMR- TSX.V, IMXPF - OTC.BB) is pleased to report results from Phase III diamond drill holes 146 to 161 at it's 100% owned Navidad project in Patagonia, Argentina. Highlights from drilling at Calcite Hill include: 83.0M OF 209 G/T SILVER IN HOLE 148 AND 80.2M OF 246 G/T SILVER INCLUDING 25.3M OF 476 G/T SILVER IN HOLE 151. The Calcite Hill soil anomaly extends for 1.4 km to the northwest of current drilling and is located along the Navidad Trend where IMA's Phase I & II drill programs 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). As a result of the success to date at Calcite Hill, IMA's Technical Committee has approved a 10,000m expansion to the Phase III drill program, thereby doubling the budgeted drill metres. This expansion will allow IMA's geologists to continue to delineate high-grade silver mineralization at Calcite Hill. New drill results from Calcite Hill (holes 146 to 152) have extended known silver mineralization another 100m to the northwest bringing the size of the main portion of Calcite Hill mineralization to approximately 275m long by 100m wide by 50 to 120m deep (see attached map). Drilling at the Connector Zone (holes 153-156) has intersected silver mineralization over long intervals outside of the current Indicated Resource. Results include 88.8m of 107 g/t silver in hole 153 and 28.8m of 148 g/t silver in hole 154; both intercepts start at surface. Mineralization in holes 153 and 154 is open to expansion to the north and northwest. Both step-out and infill drilling is required in this area and an updated resource estimate will be undertaken when this is completed. At Navidad Hill, holes 157 to 161 were collared along the southern boundary of the known resource and demonstrate that mineralization continues beyond the limits of the Indicated portion of current resource estimation. Mineralization encountered to date at Calcite Hill is predominantly hosted within trachyandesite volcanic rock and to a lesser degree within mudstone which overlies the volcanic rock. The volumetrically most important style of mineralization consists of calcite-barite veinlets and breccias with argentite-acanthite, native silver and lesser galena and chalcopyrite. In general, this style of mineralization contains high silver grades with minor amounts of lead and copper. In the upper portions of the host volcanic unit, and in the overlying mudstone, mineralization tends to be lead-rich and consists predominantly of medium-grained galena with moderate silver values. A resource estimate has not yet been done for Calcite Hill. IMA Exploration Inc. March 22, 2005 Page 2 IMA is well financed to continue to test the numerous exploration targets at Navidad with significant drill programs. The Company has over 10 years experience in Argentina and is focused on the environmentally responsible exploration and development of its' 100% owned Navidad silver discovery.
