The area of the Fairfield showing is underlain by Devonian to Upper Triassic metasediments which are intruded by granitic rocks of the Oligocene Tkope River Intrusions. An adit was driven in oxidized, massive pyrite in skarn just west of a small lake at the eastern base of Copper Butte. A sample assayed trace silver and 0.73 per cent copper. About 90 metres northwest of the adit a test pit exposes malachite in garnet skarn between footwall argillite and hangingwall marble. A sample of mineralized material assayed 45.94 grams per tonne silver and 1.20 per cent copper.
