Andesite and basalt flows, ranging from 6 to 15 metres thick, belong to the Jurassic Hazelton Group. The flows, which strike from east to southeast and dip 50 degrees south, are cut by a quartz- albite dyke which strikes south and dips 45 degrees east.

Galena and chalcopyrite occur in a one metre wide, 10 metre long altered zone along the footwall of the dyke. A 60 centimetre channel sample assayed trace gold, 23.3 grams per tonne silver, and 1.09 per cent lead (Geological Survey of Canada Memoir 212).

At about 75 metres lower in elevation, a 60 centimetre wide quartz vein, striking 110 degrees and dipping 55 degrees north, occurs in the volcanics. A selected sample, containing chalcopyrite, bornite and minor galena, assayed 0.7 grams per tonne gold, 229 grams per tonne silver, 0.96 per cent lead and 6.98 per cent copper (Geological Survey of Canada Memoir 212).
