Work on the Shyri concessions, collectively over 450 km2 in area, indicates potential for low and high sulphidation precious metal deposits in several target areas. The Shyri concessions straddle the Gañarin Belt and are immediately adjacent to IAMGold Corporation's Quimsacocha project. The Gañarin Belt is a 50 km long feature with several volcanic centers, related intrusives and numerous epithermal gold-silver prospects. Quimsacocha is the most advanced project in the Gañarin Belt. IAMGOLD first announced significant drill intersections at Quimsacocha in December 2004 and in September 2006 they reported an indicated resource of 3.4 million ounces of gold in the deposit (IAMGold Corporation press release, 27 September 2006).
