Development status: Undeveloped Prospect
The Deer Bay area is underlain by the pre-Jurassic Westcoast Complex, an assemblage of greenstone, diorite, granite, granodiorite and basalt porphyry. Associated with the greenstone are lenses of white to grey limestone, striking northwest and dipping steeply northeast. The greenstone has been intruded by coarse-grained, dark diorite sills.
Skarn alteration occurs in varying amounts in the greenstone, in the intrusive and at limestone contacts, where little or no limestone has been replaced. The skarn consists of epidote, pyroxene, amphibole and calcite, and occurs as massive lenses or as veins. Mineralization consists of chalcopyrite and magnetite, which occur locally with pyrite, pyrrhotite, bornite, malachite and azurite.
The White occurrence has been explored by four short adits located over about 120 metres:
1) Adit Number One is 36 metres long and follows pyroxene-epidote skarn in andesite and diorite that has been cut by minor feldspar porphyry dykes. Only traces of sulphides are present, but a thin quartz vein at the face of the adit assayed 0.10 per cent nickel (sample 8503k, Assessment Report 14807).(2) Adit Number Two, 5 metres long, is located 120 metres east northeast of adit Number One in skarn and diorite, and contains traces of sulphides.(3) Adit Number Three is 10 metres long and lies 150 metres east- northeast of adit Number One and follows a diorite-andesite contact. Traces of sulphides are present.(4) Adit Number Four is 3 metres long and lies 110 metres northeast of adit Number One. It exposes numerous patches, up to 3.0 metres wide, of massive chalcopyrite and pyrite with minor bornite, malachite and azurite in pyroxene-epidote skarn that is located at a diorite-andesite contact.
