David Henstridge,\nPresident, is pleased to announce the signing of an airborne electromagnetic\ngeophysical survey contract (the \"Survey\") to be performed by Skytem of\nDenmark over the Company's ¿ster Silvberg, Tomtebo and Vitturn projects in the\nBergslagen District of Sweden. The Survey, which is scheduled to commence in\nlate August 2006, will total approximately 500 line-kilometres with line\nspacings of 100 metres and covering an area of 50 km2.\n\n¿ster Silvberg: The ¿ster Silvberg mine, located 27 km south of the city\nof Falun, was once the chief producer of silver in Sweden in the fourteenth\nand fifteenth centuries, but there has been no production since the\nmid-1920's. The host rock is generally a metamorphosed, fine-grained, bedded\npotassic rhyolite tuff. Near the ore contacts, the rock is often classified as\nan \"ore quartzite\" which is actually the tuff that has been altered to mostly\nquartz, garnet, mica, minor andalusite and other metamorphic minerals. The\nmineral bodies at ¿ster Silvberg are found in cross-fractures, spatially\nrelated to the metamorphosed tuff formations, which appear to have been formed\nby the regional folding that deformed the host rocks.\nThe principal ore was an argentiferous galena that formed a columnar body\nto the 220 metre level of the mine. Flanking the galena to the north and\nsoutheast occur some narrower pyrite-sphalerite orebodies containing very\nlittle galena and traces of chalcopyrite, quartz and fluorite. Complete mine\nproduction and grade records are not available. Early records indicate that\nsilver production exceeded 32,000 ozs per year. One tabulation shows a total\nof only 2,900 ozs of silver mined in thirteen different years between 1636 and\n1920: the mine suffered several shut-downs in these centuries due to rock\ncaves. Various assays from the seventeenth and eighteenth centuries show that\nthe ¿ster Silvberg galena carried from 1,053 to 4,335 g/t silver. In addition,\nthe produced silver contained about 10% gold (from 100 to 430 g/t.)\nThe airborne survey will cover roughly 9 km strike length of favourable\ngeology that hosts the ¿ster Silvberg deposit.
