The Cape Scott occurrence is located on the ridge separating Dakota Creek and Fisherman River, in the Cape Scott area of northern Vancouver Island.
The area is underlain by the Upper Triassic Vancouver Group, Karmutsen Formation which is in fault contact with the Upper Triassic Vancouver Group, Quatsino Formation limestone and Lower Jurassic Bonanza Group volcanics.
Locally, copper mineralization is present in siliceous sections of several vertical, east striking shear zones. The shear zones range in width from 5 centimetres to 4.6 metres and lie within porphyritic to massive lava of the Upper Triassic Vancouver Group, Karmutsen Formation. When not silicified, the shear zones are unmineralized and are characterized by soft chloritic gouge. Other alteration minerals recognized are epidote, clinozoisite, carbonate and pyrite. Locally, weak disseminated chalcopyrite is present in the unaltered country rock.
Between 1968 and 1970, Quintana Minerals completed programs of prospecting, geological mapping, geochemical sampling, geophysical surveys and minor trenching on the Cape Scott claims. A 3.0 metre sample taken from chalcopyrite mineralization in a silicified shear zone assayed 2.8 grams per tonne silver and 0.73 to 1.34 per cent copper (Assessment Report 2383, page 16).
