The Hotfish showings are located southeast of Hotfish Lake, approximately 2.5 kilometres west of Deception Creek.

The area is underlain by andesitic to mafic tuffs with occasional small areas of pillow lavas and volcanic breccia, and light to dark coloured argillites of the Upper Triassic Nicola Group. These have been intruded by quartz monzonite stocks or plugs of the Takomkane batholith.

Locally, 3 small zones of sulphide vein mineralization within quartz-carbonate altered rhyodacite of the Upper Triassic Nicola Group. The showings are located just east of Hotfish Lake, about seven kilometres north of the east end of Canim Lake.

All three zones show abundant pyrite and some chalcopyrite; one zone carries stringers of sphalerite as well.

In 1991 through 2009, the Hot and Hotfish claims were explored by H.J. Wahl. Various programs of geological mapping, prospecting, geochemical sampling and a induced polarization surveys were conducted. He discovered mineralization on the Fish claims in 1994, during follow-up work on extensions of cadmium and silver soil anomalies on the Hot claim group to the northwest (Assessment Report 23869).
