Doubled the strike length of the mapped bonanza-grade silver-copper-lead mineralization at Navidad Hill. 2. Significantly expanded the size of replacement-style silver-lead mineralization which has clear bulk tonnage potential. 3. Demonstrated the potential for additional discoveries within an 8 kilometre by 3 kilometre area of favourable geology and anomalous geochemistry. NAVIDAD HILL BONANZA-GRADE STRUCTURES Cumulative strike length of known structures at Navidad Hill is now 402 metres; the steeply dipping structures have widths typically from 0.45 to 3.3 metres and occur within an area of 160 x 110 metres. The length weighted average grade of all 43 samples taken from this style of mineralization is 6,537 grams per tonne (g/t) silver (191 ounces per ton), 3.5% copper, and 16.6% lead. Outside the Navidad Hill area, several additional bonanza-grade structures have been mapped with values up to 30,510 g/t silver (897 oz/ton) (see appendix for details). REPLACEMENT STYLE MINERALIZATION Replacement style silver-lead mineralization has a cumulative strike length of over 3.2 km within a 3.8 km trend. The average grade of all 41 samples taken from this style of mineralization is 158 g/t (4.61 oz/ton) silver and 8.9% lead. Thicknesses of the replacement zones are not yet known due to sparse exposure. ADDITIONAL POTENTIAL Geologic mapping, rock and soil sampling has shown potential for additional discoveries similar in style to Navidad within an 8 kilometre by 3 kilometre area. Results received to date from an initial soil grid (278 samples) include values greater than 100 g/t silver and greater than 1% lead from areas outside Navidad Hill. Although extensive soil cover has limited the surface delineation of mineralization at Navidad, excellent potential exists for additional mineralization below this cover. IMA's Exploration Manager, Keith Patterson, M.Sc. and Daniel Bussandri, B.Sc. completed the recent mapping, rock sampling and soil sampling. IMA's Qualified Person for the Navidad project, Dr. Paul Lhotka, P.Geo., has since verified the above work in the field. The Navidad discovery is ideally located in a temperate climate zone, at an elevation of approximately 1,100 metres. It is less than one kilometre from a highway, 45 kilometres from the nearest town, 125 kilometres from the nearest railway line and 250 kilometres from a deep-sea port.

Shareholders and all interested parties are invited to visit with the Company's Management at the booth to learn more about IMA's exploration activities. ON BEHALF OF THE BOARD /s/ Gerald G.

Length weighted average of all 43 samples is 6,537 g/t silver (191 oz/ton), 3.5% copper, and 16.6% lead. This relatively small difference between average and length weighted average demonstrates the remarkable consistency of grade within the Navidad Hill structures.
