Andesites of the Jurassic Hazelton Group are cut by quartz- albite dykes. A silicified zone in red andesite contains quartz veins and fractures mineralized with bornite, chalcopyrite and chalcocite. The zone, which strikes 105 degrees and dips 67 degrees north, is up to 20 metres long and 2 metres wide. A 2 metre sample across the zone assayed 2.9 per cent copper, 48 grams per tonne silver and 0.17 grams per tonne gold (Property File: Lay and Mandy, 1937).

About 500 metres to the northwest, chalcopyrite, pyrite and minor galena occur in narrow seams along faults and joints in a zone 1.2 metres wide. A selected sample assayed trace gold, 28.8 grams per tonne silver and 2.16 per cent copper (Geological Survey of Canada Memoir 212).

About 300 metres northeast, a silicified shear zone, along the hangingwall side of a 3.7 metre wide quartz-albite dyke, contains a 35 centimetre wide quartz vein with chalcopyrite and bornite. The dyke strikes 170 degrees and dips 45 degrees east. A 35 centimetre channel sample assayed 0.7 grams per tonne gold, 205 grams per tonne silver and 1.16 per cent copper (Geological Survey of Canada Memoir 212).
