Dec 07, 2005 (A Wilson) - Mineralization is hosted within graphite shcist containing carbonate veines. Pyrite, pyrrhotite is common within the schist. Lamprophyre dikes are found at depth. The mineralized shear zone strikes east from the north shore of Mission Lake. The zone is strongly mineralized with pyrite and quartz veining and carbonate are common. The shearing may be related to the emplacement of the nearby Mission Stock.

Dec 07, 2005 (A Wilson) - The original drill hole (Sutherland DDH - 4) intersected what appears to be graphitic schist that returned $4.90 Au over 1.5 feet. A hole drilled in 1985 intersected graphitic tuff that returned assays of 0.014 oz/t Au and 0.03 oz/t Ag and 0.142 oz/t Au and 0.06 oz/t Ag. Pb assays in the same drill hole ranged from 6 ppm to 3400 ppm in the same section of core as the elevated gold and silver assays.
