Capsule Geology

No geological information is available. Rocks submitted to Energy, Mines and Petroleum Resources for assaying show values in gold, silver and copper. Sample 1: 6.8 grams per tonne gold, 34.3 grams per tonne silver and 22.0 per cent copper. Sample 2: 13.7 grams per tonne gold, 75.4 grams per tonne silver and 5.0 per cent copper. Sample 3: nil gold, nil silver and 0.7 per cent copper (Minister of Mines Annual Report 1924, page 224).

Rocks in the area are composed of Upper Triassic Karmutsen vol- canics of the Vancouver Group. They are characteristically porphy- ritic and andesitic to basaltic in composition. Also known in the area are granodiorites of the Jurassic Island Plutonic Suite.
