The Company conducted an extensive, 86-hole helicopter-based drill campaign in the summer of 2010, designed to test the true thickness of mineralization in the Main zone, and to extend its boundaries in all directions. Property wide prospecting work was also undertaken, leading to a number of new discoveries to the north, east and west of the Main zone.
Highlights of the drilling included the extension of the known strike length of mineralization at the Main zone from approximately 600 m to over 800 m, and increased the down dip width of the system from 100 to 200 m, to roughly 300 to 400 m depending on location. Drilling 300 m north of the Main zone in what is now referred to as the “North Extension”, the Company discovered a silver-lead-zinc mineralized stockwork within a previously untested subvolcanic andesite intrusion.
Drilling highlights included drill hole BA-2010-136, which returned 136 g/t silver, 0.63% lead and 0.53% zinc over 3.05 m; 82 g/t silver, 1.06% lead and 1.20% zinc over 12.19 m; and 62 g/t silver, 0.54% lead and 1.72% zinc over 3.05 m; within a 250+ m wide VMS mineralized system. Drilling in the North Extension ultimately defined a contiguous zone of intensely developed stockwork massive sulfide mineralization (the “Stockwork” zone). This new zone is open to the south in the direction of the Main zone, and open to the north in the direction of the Bod zone, with dimensions of approximately 350 m by 300 m.
