The area is underlain by east striking, 50 degree south dipping tuffs of the Jurassic Hazelton Group. A 5 metre wide brecciated and altered zone, between two intersecting faults, is mineralized along minute fractures with pyrite and minor galena and molybdenite. A typical dump sample assayed 15.8 grams per tonne silver, 0.72 per cent lead and 0.11 per cent molybdenite (Geological Survey of Canada Memoir 212). About 50 metres to the north, sheared and altered tuff contains minor pyrite, galena and sphalerite.
