The claims are underlain by Lower Jurassic Hazelton Group, Telkwa Formation volcanics comprised mainly of andesitic to rhyolitic flows, tuff and breccia. The volcanics are intruded by Late Cretaceous to Tertiary granodioritic stock with associated quartz feldspar porphyry dikes.

A fracture in the volcanics strikes 230 degrees and dips 80 degrees southeast. Fracture infilling hosts pyrite, chalcopyrite, bornite and malachite. In 1973, a sample assayed: 0.97 per cent copper and 8.2 grams per tonne silver (Assessment Report 4891).

A set of parallel veins, approximately 10.7 metres apart cross- cut maroon andesite and strike north-south dipping 70 degrees east. These quartz feldspar porphyry dikes range between 0.3 to 0.9 metres wide and 161 to 201 metres in length. Mineralization consists of pyrite, chalcopyrite, minor galena and secondary malachite and azurite. In 1973, a sample assayed: 5.5 per cent copper, 191.3 grams per tonne silver and 1.47 grams per tonne gold (Assessment Report 4891).
