A quartz vein containing sphalerite, galena, chalcopyrite and pyrite occurs at the crest of a small anticline in argillites of the Jurassic to Cretaceous Bowser Lake Group. The vein, striking 110 degrees and dipping 45 degrees south, is 1.0 to 1.5 metres wide and about 12 metres long. It is cut off to the north by an east striking, 45 degree north dipping fault. A 1.5 metre sample assayed 240 grams per tonne silver, 7.2 per cent lead, 24 per cent zinc, 0.9 per cent copper and 0.34 grams per tonne gold (Minister of Mines Annual Report 1931). Thirty metres to the north, a 3 to 12 metre wide feldspar porphyry sill strikes 120 degrees and dips 15 degrees north.
