Quartz veins occur in argillites and quartzites of the Jurassic to Cretaceous Bowser Lake Group. The quartz veins, generally associated with shear zones averaging 0.6 metre wide, are mineralized with pyrite and contain traces of gold and silver. A vein 150 metres northwest of an adit assayed 13.7 grams per tonne silver and trace gold over 3.6 metres (Minister of Mines Annual Report 1928). The vein is also mineralized with areas of copper-stain and molybdenite which assayed 61.7 grams per tonne silver and 0.7 gram per tonne gold (Minister of Mines Annual Report 1930). The shear zone strikes 085 degrees and dips 60 degrees south.

Sampling of the quartz veins in 1988 revealed that they are variably mineralized with chalcopyrite, galena, sphalerite and pyrite. Assays yielded up to 2.7 per cent copper, 298 grams per tonne silver, 12.03 per cent lead, 5.4 grams per tonne gold and 0.7 per cent zinc (Assessment Report 18831).
