The Fang showing is located just north of Perkett Creek on Jervis Inlet.

The region is underlain by Jurassic to Tertiary Coast Plutonic Complex quartz monzonite, quartz diorite and diorite near the contact with volcanic and sedimentary rocks of the Lower Cretaceous Gambier Group. The Gambier Group comprises andesitic to rhyodacite flows and pyroclastics, greenstone, argillite, minor conglomerate, limestone and schist. Zones of faulting and shearing are locally common near intrusive contacts. These zones exhibit alteration and replacement mineralization.

The main mineralized zone occurs near the contact between quartz feldspar porphyry and volcanic rocks. The zone, sheared and oxidiz- ed, contains pyrite, chalcopyrite and pyrrhotite. Float containing chalcopyrite, malachite and pyrrhotite have been located in the area (one sample assayed 8.12 per cent copper, 130.26 grams per tonne silver and 0.686 grams per tonne gold).
