The claims are underlain by Lower Jurassic Hazelton Group volcanics of the Telkwa Formation. The volcanics are comprised of massive purple to green andesite, andesitic to rhyolitic tuff and flows, crystal tuff and lithic tuff. Massive andesite is commonly porphyritic with plagioclase phenocrysts.

Quartz-calcite and quartz veins occur along shear planes and fractures with associated epidote and chlorite. Malachite, azurite and bornite are reported as occurring in the fractured Hazelton andesite.
