Andesites of the Jurassic Hazelton Group are cut by shear zones and quartz veins mineralized with pyrite, chalcopyrite, pyrrhotite and arsenopyrite. A shear zone, up to 6 metres wide, contains two quartz veins trending 75 degrees and dipping 45 degrees north. A sample of a 38 centimetre vein assayed 0.2 grams per tonne gold, 24 grams per tonne silver and 0.39 per cent copper (Geological Survey of Canada Memoir 329). About 16 metres to the east, a 3.4 metre sample of disseminated pyrite and chalcopyrite in a shear zone assayed 0.2 grams per tonne gold, 12.3 grams per tonne silver and 0.23 per cent copper (Geological Survey of Canada Memoir 329). A 0.5 metre wide mineralized quartz vein occurs 53 metres further to the east.
About 120 metres to the north, between two lakes, a 15 to 30 centimetre wide vein, striking 010 degrees and dipping 45 degrees east, is exposed for 7.6 metres. A sample assayed 0.3 grams per tonne gold, 2.4 grams per tonne silver and 10.20 per cent zinc (Geological Survey of Canada Memoir 205).
