Mar 30, 2012 (A Wilson) - Mineralization consists of disseminated pyrite, pyrrhotite and some chalcopyrite in a chlorltized shear zone exposed for 25 feet along strike and 10 feet across strike. From DDH No. 66-3, from 23'-25 ft., assays returned nil in gold, silver and nickel, and 0.07% Cu. Footage from 8-12 ft. in DDH No, 66-4 returned nil values in gold and silver, and 0.357% copper, and 0.0617% nickel. The interval of 12-13 ft. assayed nil Au and Ag and 0.027% Cu and 0.1507% Ni. DDH 66-13 returned nil Au, Cu and Ni and 0.11 oz/t Ag over 5 feet. A grab sample assayed 1.25% Cu and 0.72 oz/ton Ag.
