The OP #6 showing is underlain by regionally metamorphosed greenschist facies subaerial massive and amygdaloidal basalt flows of the Vancouver Group, Upper Triassic Karmutsen Formation. Black argillites and limestones occur as interbedded sediments.

Copper mineralization is strongly associated with carbonate (ankerite?) veining and lenses. Chalcopyrite and malachite occur within these veins which cut moderately hematizated amygdaloidal basalts.

A 15 centimetre carbonate (ankerite?) vein sample with chalcopyrite, malachite, and pyrite, assayed 12.3 per cent copper (Assessment Report 9830).
