The Horse Hump occurrence is located 500 metres east of Tofino Creek, approximately 900 metres northeast of the creek mouth, and 25 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 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 assemblage consists of garnet, epidote, pyroxene, amphibole and calcite.

The occurrence is comprised of a 50-centimetre wide lens of massive chalcopyrite which occurs in the hanging wall of a thin limestone band.

Massive chalcopyrite, 15 to 25 centimetres wide, is also exposed approximately 180 metres to the southwest, possibly in the same limestone horizon. The mineralization occurs in the hanging wall of the limestone where this unit is folded into an open, northeast plunging anticline.

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. A sample (960) of massive sulphide in skarn, from the area of the occurrence (Road Cut), assayed 14.0 per cent copper and 75.2 grams per tonne silver (Assessment Report 17284).

The Road Cut occurrence, approximately 80 metres northwest of the Horse Hump showing was prospected and sampled in 2014 by C. Zimmer and S. Scott. Five rock samples taken across the exposure assayed 3.16 to 10.95 percent copper, 0.09 to 0.665 gram per tonne gold and 13.1 to 50.7 grams per tonne silver.
