(IMR-AMEX, IMR-TSX.V) is pleased to announce results from 35 diamond drill holes at its Navidad Silver Project in Patagonia, Argentina, from the Phase IV drilling programs that commenced in January of 2006. Phase IV drilling to date has focused on further defining the Calcite NW and Calcite Hill deposits, as well as testing of several geological/geophysical targets away from the main mineralized trends. Highlights of the drilling at Calcite NW include hole NV06-262 with 25.2 metres (m) averaging 146 grams/tonne (g/t) silver including a higher-grade section of 8.54m averaging 385 g/t silver, as well as NV06-264, which contained 28.4m averaging 127 g/t silver including 6.85m of 455 g/t silver (Table 1). At Calcite Hill hole NV06-272, on the northern limit of the known resource boundary, returned 9.86m averaging 401 g/t silver. The zone remains open towards the north at shallow depths. A small area of Galena Hill has also been drilled on tight centres to allow calculation of the optimal drill spacing and to collect more material for metallurgical testing. As the Phase IV program continues drilling will also target: 1) the Esperanza Trend, 2) delineation of the high-grade mineralized zone at Loma de la Plata, which has only been tested by 5 drill holes to date (News Release 24, October 13, 2005), and 3) initial testing of other targets located along the 8km Argenta Trend. As expected, infill drilling at Galena Hill produced long intercepts of silver and lead mineralization. An example of one of the Galena Hill infill holes is NV06-275, with 120m containing 218 g/t silver and 4.8 percent (%) lead with a higher-grade, upper-part of 27.8m, starting at just 33m depth, that contains 539 g/t silver and 9.3 % lead. Similarly, hole NV06-279 produced 156.8 m averaging 121 g/t silver and 4.8 % lead including a higher-grade interval of 42m averaging 231 g/t silver and 10.2 % lead in its upper portion. For convenience, the silver equivalent values including lead have been shown in the table of results. In many cases the lead accounts for as much as half of the potential metal value at Galena Hill (see formula in the foot notes of table for details of the calculation method). Galena Hill infill drilling will determine the optimal drill spacing and orientation required to upgrade the resource from the indicated to the measured category. The holes released represent three section lines of five holes each with spacing between the hole collars and lines of 25m. All of the holes were drilled towards grid north at -75 degrees. Additional infill holes will be drilled oriented -75 degrees grid south on intermediate section lines at 25m collar spacing, thereby reducing the section lines spacing to 12.5m. Prior drilling was done at a section spacing of roughly 80 metres with holes spaced at approximately 60 metres. The results of holes released represent 6,633 metres of drilling of the more than 9,000 metres already drilled in 2006, bringing the life of the project total to over 50,000 metres. Reconnaissance drilling included 4 holes drilled between the Esperanza and Argenta trends. Drilling at Calcite NW included 14 holes, while drilling at Calcite Hill included 2 holes. An infill-drilling program at Galena Hill comprised 15 holes. The drill is currently working on the Esperanza Trend. News Release April 5, 2006 IMA Exploration Inc.

True thickness has not been calculated for these holes. 2. All length weighted averages (LWA) are "uncut" i.e. have no grade capping. 3. Silver equivalent calculated using US$6.00/oz silver and $0.35/lb lead. (AgEq = Ag + (%Pb*10,000/250). No attempt has been made to adjust these relative values by accounting for metallurgical recoveries, as insufficient information is available to do so. This is the same method as used in the resource calculation release on February 16, 2006. 4. A complete list of all results to date is available on IMA's website (www.imaexploration.com).
