Mineralization Comments

Oct 10, 2017 (C Ravnaas) - Grade: 4.15% Cu, 0.03 opt Au, 1.0 opt Ag over 1.0 m (chip)


Oct 10, 2017 (Therese Pettigrew) - Chalcopyrite, pyrite, and pyrrhotite, with low gold values, occur as a replacement of the rims in pillow lava along the strike of the flows over a distance of a mile. Another type of mineralization occurs as copper and nickel sulphides along joints in a mafic intrusion. Mineralized areas are small. Sampling from No. 1 Trench is reported to average 4.15% Cu, 0.03 opt AU and 1 opt Ag over a width of 3 ft and length of 12 ft (Shklanka, 1969).
