Capsule Geology

Granodiorite of the Cretaceous to Tertiary Coast Plutonic Complex intrudes Jurassic Hazelton volcanics. Three parallel fracture zones, which strike 140 degrees and dip 40 degrees east, occur in the granodiorite. The fractures contain quartz lenses, up to 1.5 metres wide, which locally contain coarse pyrite and chalcopyrite. A 40-centimetre channel sample of one vein assayed 12.3 grams per tonne gold and 78.2 grams per tonne silver (Geological Survey of Canada Memoir 212).
