Massive greenstone and siliceous rhyolite of Mesozoic to Paleozoic age are intruded by chloritic fine-grained quartz monzonite, granodiorite, and feldspar porphyry of the Cretaceous-Tertiary Coast Plutonic Complex. Pyrite, chalcopyrite and molybdenite occur as disseminations, as fracture infillings, and within quartz veins along the contact between the volcanics and intrusives. The mineralized zone trends northwest for about 360 metres. A 50 metre chip sample assayed 0.04 per cent copper and 0.01 per cent molybdenum (Assessment Report 800).
The Old Timer showing, probably 500 metres to the northwest, is a quartz vein with chalcopyrite, within intrusive rock. A sample assayed 1.0 grams per tonne gold, 27.4 grams per tonne silver and 3.4 per cent copper (Minister of Mines Annual Report 1914). The Oxford showing is also in the area.
