The showing is located just above sea level on Houston Stewart Channel, one kilometre west of Point Langford.
The beach outcrop was discovered in 1968.
The area is underlain by greenstone of the Upper Triassic Vancouver Group Karmutsen Formation which is cut by quartz monzonite of the Carpenter Bay pluton, part of the Tertiary Kano Plutonic Suite (Geological Survey of Canada, Paper 90-10, pages 59-87). Copper mineralization occurs in small veins in the rocks. A beach outcrop of a well-mineralized porphyry gave values of 7.08 per cent (across 60 centimetres) and 8.95 per cent (float) copper (Assessment Report 1245).
