The Foremost Copper occurrence is located west of Tofino Creek, approximately 1.2 kilometres north of the creek mouth and at an elevation of about 150 metres, 24 kilometres northeast of Tofino, B.C.

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 northwest striking, steeply dipping 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. The skarn comprises garnet, epidote, pyroxene, amphibole and calcite.

At the occurrence, a 1.8 metre wide band of magnetite dips 75 degrees southeast between a diorite footwall and a limestone hanging wall.

Approximately 60 metres to the southwest another, 2.4 metre wide band of magnetite with chalcopyrite is present, dipping steeply below a band of limestone. A thick band of skarn in the limestone hanging wall contains chalcopyrite, and at the portal of an adit in the footwall, magnetite with minor chalcopyrite and pyrrhotite are present.

In 1985, Seminole Resources Inc. completed a program of geochemical sampling, geological mapping and a ground magnetometer survey on the area as the Winter 1 claim. During 1988 through 1991, Stage Exploration Ltd., later Stag Holdings, completed programs of geochemical sampling and ground geophysical surveys on the area as part of the Deer Bay property.
