The Hot occurrence is located east of the Cypre River, approximately 1.1 kilometres northeast of River Island, and 15 kilometres north of Tofino, B.C.

The area is underlain by a thick succession of Paleozoic Sicker Group volcanics and sediments that have been intruded by numerous dykes, sills and plugs ranging from gabbro to granodiorite in composition.

The Sicker rocks comprise predominantly pyroclastic mafic to felsic volcanics with minor intercalations of chert, argillite and siltstone. The pyroclastics range from coarse lapilli (rarely breccia) tuffs to dusts tuffs. Generally, the strata have an average strike of 150 degrees and dip of 50 degrees. Stocks of mafic intrusives belonging to the pre-Jurassic Westcoast Complex disrupt area strata.

Locally, north striking fissures in meta-andesites measure from 30 to 60 centimetres in width and are reported to contain chalcopyrite, malachite, chlorite and epidote. A grab sample of this material assayed 2.36 per cent copper, 17.14 grams per tonne silver and 0.69 grams per tonne gold (Assessment Report 3443).

Nearby, on the Hot 9 claim, east-west striking fractures, exposed in a trench (No.1), assayed up to 1.72 per cent copper and 10.3 grams per tonne silver (Assessment Report 3443).

In the same area, a trench (No.2), exposed an altered gabbro with epidote, actinolite and quartz hosting chalcopyrite and malachite mineralization.

In 1970 and 1971, Thunder Valley Mines completed programs of geological mapping, silt and soil sampling and ground and airborne geophysical surveys on the area as the Cats Eye and Hot claims. During 1985 through 1987, BHP-Utah Mines completed programs of geological mapping, rock, silt and soil sampling and ground geophysical surveys on the area as the Cypress, Maypay and Whitecliff claims. In 2010, 2011 and 2012, Catface Copper Mines Limited completed programs of rock, silt and soil sampling on their large Catface NE property on the Bedingfield Peninsula.
