Highlights from Calcite Hill drilling include hole 138 which intersected 123.6M OF 139 G/T SILVER and hole 143 which intersected 46.6M OF 300 G/T SILVER including 10.3M OF 1,257 G/T SILVER. At Navidad Hill, infill drill holes 139 and 142 have intersected significantly higher grades than predicted by the resource block model, including 17.8M OF 1,037 G/T SILVER in hole 139 and 34.5M OF 1,220 G/T SILVER INCLUDING 20.2M OF 1,979 G/T SILVER in hole 142. To date, over 32 diamond drill holes have been completed at Calcite Hill where continued Phase III drilling is currently focused. Results are currently pending for 17 of these as drilling has proceeded very rapidly of late. Drill holes have been collared over an area of approximately 500m long by 100 to 300m wide. Significant results to date include: ------------------------------------------------------ Calcite Hill Core Length Silver Grade Hole metres grams/tonne ------------------------------------------------------ NV04-88* 72.3 202 ------------------------------------------------------ NV04-122* 20.2 102 ------------------------------------------------------ NV04-124* 122.6 195 ------------------------------------------------------ NV04-126* 100.3 156 ------------------------------------------------------ NV05-138 123.7 139 ------------------------------------------------------ NV05-143 46.6 300 including 10.3 1,257 ------------------------------------------------------ * = previously released Mineralization encountered to date at Calcite Hill is zoned. In the upper part, at and near the contact of the host trachyandesite volcanic rock, the mineralization is galena-rich with moderate silver content. This mineralization type comprises medium-grained galena with rare pyrite and few or no other visible sulphide minerals. These occur predominantly as breccia infill and veinlets within the host volcanic rock and as matrix to overlying sedimentary rocks (such as in the upper parts of holes 88, 124 and 138). Lower down within the volcanic host rock, veinlets and breccias have little or no galena but commonly contain visible native silver and black sulphides suspected to be argentite-acanthite (AgS) and perhaps stromeyerite (AgCuS) within a gangue of calcite, barite and lesser silica (lower portions of holes 88, 124, 138 and 143). The Calcite Hill mineralization is entirely sulphide in nature with no significant quantities of metal oxides. Both styles occur over significant vertical thicknesses and mineralization is spatially associated with and hosted by the same latite volcanic host rock which hosts the mineralization at Galena Hill and Navidad Hill. No resource estimate has yet been made of the Calcite Hill mineralization to date. News Release March 4, 2005 IMA Exploration Inc. Page 2 -------------------------------------------------------------------------------- At Navidad Hill, holes 139 to 142 were completed surrounding hole 90 on the southwest flank of Navidad Hill to provide more detailed information on this zone of very high-grade silver mineralization. Of these, holes 139 (17.8m of 1,037 g/t Ag) and 142 (34.5m of 1,220 g/t Ag) intersected significantly higher grade than that predicted by the Snowden resource block model. This new drill data will help to define the high-grade material in future block model resource estimates. Mineralization in this area consists of mixed sulphides and oxides along the sedimentary-volcanic contact including argentite-acanthite, stromeyerite, galena, and copper-silver oxides. 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/. IMA is well financed with over $9 million in its treasury 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 exploration and development of its' 100% owned Navidad silver discovery. Additionally, IMA will be exhibiting at Booth #2422 at the 2005 Prospectors and Developers Association of Canada Conference in Toronto from March 6-9, 2005. Shareholders and investors are invited to attend to meet with management and hear about our recent developments.
