The Hetty Green past producer is located on the eastern side of Tofino Creek, approximately 1 kilometre north of the creek mouth, and 24 kilometres northeast of Tofino, B.C.

The Deer Bay area is underlain by the pre-Jurassic Westcoast Complex, an assemblage of greenstone, quartz diorite, 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 and at intrusive-limestone contacts, but little or no limestone has been replaced. Skarn consists of frequently coarse garnet, epidote, pyroxene, amphibole and calcite, and occurs as massive lenses or in disseminated form. Mineralization consists of chalcopyrite, magnetite, pyrite, and pyrrhotite, with minor amounts of bornite, molybdenite and powellite. All these minerals can be found together in varying proportions as small pods within the skarn. Magnetite and molybdenum minerals are mutually exclusive.

In 1980, a chip sample was completed over a surface exposure of magnetite-chalcopyrite pods near the intrusive contact and assayed 0.511 per cent molybdenum over 20 metres (Assessment Report 8106). Two diamond drill holes were performed on the site but only intercepted traces of chalcopyrite and molybdenite.

The Hetty Green mine has been developed along two levels, the 120 and the 210-foot levels. The 120-level portal lies 10 metres east of Tofino Creek and exposes a 20 metre long, 5 metre wide skarn lens. The 210-level portal and the adjacent 10 by 5 metre open cut, are located 75 metres east of the lower level adit, and may be the source of 194 tonnes of selected ore that was shipped in 1905. This material contained 62 grams of gold, 5,225 grams of silver and 13,326 kilograms of copper (National Mineral Inventory Card 92F/4 Cu 2).

Forty metres west of Tofino Creek, a limestone band dips irregularly into the hillside. Along the foot wall, greenstone and, locally, diorite are intensely mineralized with magnetite. An adit exposes the limestone hanging wall, where abundant chalcopyrite and pyrrhotite are present at the greenstone contact. A skarn-altered band higher up in the hanging wall contains some disseminated molybdenite. About 30 metres to the north veinlets of molybdenite are present.

In 1980, Pawnee Oil Corp. completed 330.5 metres of drilling, over four sites, on the Pawnee Claim Group. 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.
