Highlights of the current results include 29.6M OF 236 G/T SILVER AND 5.38% LEAD IN HOLE 167, AND 51.0M OF 168 G/T SILVER IN HOLE 168. Mineralization at Calcite Hill has now been defined 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 (see attached map). 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 Navidad Hill, Galena Hill and the Connector Zone. A new resource estimate at Calcite Hill is planned to begin shortly and will be conducted by Snowden Mining Industry Consultants based on the 36 drill holes completed at Calcite Hill during Phase III (as of April 18, 2005). To date, IMA has completed 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 in just 17 months. The Calcite Hill mineralization is expected to add significantly to the existing resource base. In addition, the company reports that Connors Argentina S.A. is now on site at Navidad to begin the additional 10,000m that were added to the Phase III drill program. The primary focus of this program will be to continue to expand the high-grade silver-lead mineralization at Calcite Hill. The Calcite Hill zone is open along strike to the northwest where a silver-in-soil anomaly extends for a further 1.4 km beyond the present limit of drilling, and also to the northeast in the area nearest Navidad Hill. Complete results from drill holes 162 to 174 are shown in Table 1, significant intercepts to date from Calcite Hill include the following: -------------------------------------------------------------------------------- DRILL HOLE INTERCEPT (M) SILVER (G/T) LEAD (%) -------------------------------------------------------------------------------- NV04-88* 72.3 202 3.45 -------------------------------------------------------------------------------- NV04-124* 122.6 195 0.74 -------------------------------------------------------------------------------- NV04-126* 196.1 113 0.44 -------------------------------------------------------------------------------- NV05-138* 123.3 139 1.07 -------------------------------------------------------------------------------- NV05-143* 46.6 330 0.39 -------------------------------------------------------------------------------- NV05-148* 83.0 209 1.23 -------------------------------------------------------------------------------- NV05-149* 124.2 135 0.29 -------------------------------------------------------------------------------- NV05-151* 80.2 246 0.78 -------------------------------------------------------------------------------- NV05-162 32.3 176 0.13 -------------------------------------------------------------------------------- NV05-165 50.6 102 0.92 -------------------------------------------------------------------------------- NV05-167 29.6 236 5.38 -------------------------------------------------------------------------------- NV05-168 51.0 168 0.04 -------------------------------------------------------------------------------- NV05-170 50.9 124 1.93 -------------------------------------------------------------------------------- NV05-171 43.9 171 2.82 -------------------------------------------------------------------------------- * denotes previously released results NEWS RELEASE APRIL 19, 2005 IMA EXPLORATION INC. PAGE 2 -------------------------------------------------------------------------------- Silver mineralization at Calcite Hill is predominantly hosted within the same trachyandesite volcanic rock and overlying mudstone which hosts mineralization at Galena Hill. Mineralization consists of two distinct styles, one consisting of calcite-barite veinlets and breccias with argentite-acanthite, native silver and lesser galena and chalcopyrite, the other consisting of veins and breccias containing medium-grained galena and rare native silver. Dr. Paul Lhotka is IMA's Qualified Person for the Navidad project under National Instrument 43-101 regulations and has overseen all aspects of the current exploration program. IMA has implemented a rigorous program of quality assurance and quality control at the Navidad project, for complete details of this and for more maps depicting the work described herein please visit IMA's web site at http://www.imaexploration.com/.
