Granodiorite of the Cretaceous to Tertiary Coast Plutonic Complex is cut by quartz-feldspar porphyry and later quartz diorite and lamprophyre. The lamprophyre dykes are cut by two parallel faults, 160 metres apart, striking 056 degrees and dipping 60 to 70 degrees southeast. Quartz veins, 0.2 to 1.0 metres wide, follow the faults and are mineralized with small seams of chalcopyrite, pyrite, galena, tetrahedrite and sphalerite. The veins are up to 270 metres long and some are carbonated and contain siderite. A grab sample assayed 66 grams per tonne gold and 17 grams per tonne silver (Minister of Mines Annual Report 1930). A sample of a quartz vein in the area assayed 0.07 per cent zinc (Assessment Report 13104).
