The showings occur in the Lower Jurassic Hazelton Group vol- canics of the Telkwa Formation. Mineralization occurs as small veinlets in the fracture zones and joints in the massive dark purple, red and grey andesites, andesitic flows, and tuff. Dominant fracturing is 315 degrees and dipping 70 degrees south.

At 602 metres elevation, mineralization in the purple andesites consists of chalcopyrite, bornite, malachite, and azurite in joint planes and poorly developed lines of cleavage. An open cut failed to find significant mineralization.

At 660 metres elevation, the andesite is sheared across a width of 1.8 metres and hosts copper mineralization. Selected samples from this shear assayed trace gold, 123.4 grams per tonne silver and 1.8 per copper (Geological Survey of Canada Memoir 223, (Rev.), page 125).
