The area is underlain mainly by Upper Triassic Vancouver Group, Karmutsen Formation greenstones and lesser Triassic to Jurassic Kunga Group grey limestones and argillite. Minor quartz feldspar porphyries intrude both units and may be related to a stock of the Middle to Late Jurassic Burnaby Island Plutonic Suite which occurs to the southeast.
Copper mineralization is confined to a silicified fault bounded shale wedge (0.5 by 2.0 metres), in part graphitic but non-calcareous. It is surrounded by non-mineralized chloritized andesites. Bornite and malachite are the principle copper minerals and occur in cross- cutting quartz veinlets and fractures. A typical sample assayed 1.8 per cent copper and 3.4 grams per tonne silver (Assessment Report 6121). Falconbridge Limited held the property as the P and Q claims in 1976.
