The Hillside showing is located about 1.0 kilometre east of the main dam on Anyox/Falls Creek, about 3.0 kilometres northwest of Anyox. The area has been explored for copper in the past.

The region is underlain by a roof pendant, consisting of volcanic and sedimentary rocks, within the Eocene Coast Plutonic Complex. These pendant rocks have been correlated with Middle-Upper Jurassic Hazelton Group rocks and overlying upper Middle to Upper Jurassic Bowser Lake Group sedimentary rocks (Geological Survey of Canada Open File 3453). The Hazelton rocks consist of variably chloritized pillow and massive basalt with minor mafic tuffs. The overlying Bowser Lake sediments consist of siltstone and sandstone with minor chert and limestone. These rocks have been deformed by two phases of folding, a north-northeast trending phase, and an east-northeast trending phase.

The occurrence comprises two individual showings. The Hillside showing consists of steep, east trending, lens-like bodies in altered andesitic pillow flows and pillow breccias. The mineralization consists of massive to disseminated pyrrhotite, pyrite and chalcopyrite contained mainly in altered quartz biotite schist zones within the volcanics. The mineralization can be traced for at least 244 metres.

South of the Hillside showing, at an elevation of 351 metres, galena mineralization is found in a steeply dipping, leached quartzose zone trending 080 degrees within altered pillow flows.
