(IMR - TSX.V, IMXPF - OTC-BB) is pleased to announce Phase II drill results from holes 89 to 96 on the Company's 100% owned Navidad Silver-Lead-Copper discovery in Patagonia, Argentina. Highlights include drill hole 90 on the Navidad Hill target that returned 35.8 METRES (M) OF 2,850 GRAMS PER TONNE (83.2 OZ/T) SILVER INCLUDING 7.3M OF 11,995 G/T (350.3 OZ/T) SILVER beginning at 16.5m depth (see attached map). These latest results, in addition to those from hole 88 (a 470 metre step-out from Navidad Hill, see Sept. 8, 2004 news release), clearly demonstrate the potential for outlining significant additional resources at Navidad Hill and Calcite Hill. Both of these targets are northwest of the Galena Hill deposit, where after Phase I drilling the Company announced a significant deposit that contains an Indicated Resource of 207 million ounces of silver and 1.1 million tonnes lead (see May 25, 2004 release). Drill hole 90 was drilled at an inclination of -45(Degree) towards the northeast on the western flank of Navidad Hill, approximately 275m northwest of drill holes 1 and 2 and in an area of little or no outcrop. Bonanza-grade mineralization in drill hole 90 contains semi-massive silver-copper-lead sulphides and/or sulphosalts. In several locations native silver occurs as fine veinlets and grains up to 5mm in size (see photo posted at www.imaexploration.com). Mineralization occurs on the western flank of the Navidad volcanic dome and, as is common in other zones at the project, is strongest at the contact between overlying mudstone and trachyandesitic volcanic rocks. The mineralization is believed to be stratigraphically controlled and to be gently dipping to the southwest. Based on this assumption, the true thickness of this zone is interpreted to be 85-90% of the intersection. Bonanza-grade mineralization in hole 90 appears to be related to, and in the same stratigraphic position as, that previously reported in hole 73. Upcoming results from the surrounding drill holes (99, 100, 104, 116, etc) should confirm the orientation and extent of this important new zone. Drill hole 89 was drilled in the same area as hole 90 on the flank of Navidad Hill, between holes 90 and 73 but was drilled down a northeast-trending fault and therefore returned only 10.9m of 109 g/t silver. It is expected that tightly spaced, follow-up drilling will be required to fully define this very high-grade zone. Of the remaining holes (tabulated below), 91 and 92 were drilled on Barite Hill and 93 was a reconnaissance hole drilled between Galena and Barite Hills that, significantly, intersected 9.1m of 1.4% lead. Holes 94, 95, and 96 were drilled on the southwestern edge of the Connector Zone. Drill results for the remaining holes in Phase II, holes 97 to 120, will be released as they become available. The Company has included a rigorous quality assurance and quality control program at the Navidad project including blank, duplicate, and standard samples inserted randomly into the sample sequence. A complete description of this procedure is available on the Company's website at www.imaexploration.com. Dr. Paul Lhotka, P.Geo. is the Qualified Person for the Navidad project and has overseen all aspects of the current program. NEWS RELEASE SEPTEMBER 15, 2004 IMA EXPLORATION INC.
