Quartz filled shear zones, striking north to northeast, occur in Jurassic to Cretaceous Bowser Lake Group sedimentary rocks. The rocks consist of coarsely interbedded black argillites, impure greenish quartzites, and fine-grained, grey greywackes which have been tightly folded along a northeast trending axis. The folds have associated shears and faults with quartz veins. Pyrite, galena, sphalerite, chalcopyrite, possibly smithsonite, and secondary hydrozincite occur in the veins as disseminations and coarse blebs.

Drill hole #1 intersected 3.75 per cent zinc, 0.27 per cent copper, 0.02 per cent lead, 20.6 grams per tonne silver and 0.3 grams per tonne gold over 2.4 metres. Drill hole #3, 180 metres to the northeast, intersected 5.00 per cent zinc, 0.69 per cent copper, 0.10 per cent lead, 37.7 grams per tonne silver and trace gold over 50.8 centimetres (Property File: White, 1969).
