The area is underlain by andesites of the Jurassic Hazelton Group, which are cut by aplite dykes. The Golconda showing, at 600 metres elevation, is a 150 metre long, east trending shear zone containing bornite, chalcopyrite, malachite and limonite. The zone is at least 8 metres wide and chip samples taken across this width assayed 4.16 per cent copper and 86.1 grams per tonne silver (Prop- erty File: Phendler, 1968). Drilling intersected 14 metres of 3.30 per cent copper (Property File: Phendler, 1968).

To the northwest, at 460 metres elevation, a sheared aplite dykes in andesite contains disseminated chalcopyrite, galena, spha- lerite and pyrite. A grab sample assayed 0.34 grams per tonne gold, 96 grams per tonne silver, 1.27 per cent copper, 0.25 per cent lead and 1.21 per cent zinc (Geology, Exploration and Mining in British Columbia, 1969).

On the Four Aces claim, 450 metres northwest of the Golconda showing, quartz veins are mineralized with pyrtie, chalcopyrite and minor bornite, galena and sphalerite. A grab sample assayed 0.05 per cent copper, 38.4 grams per tonne silver, and 0.2 grams per tonne gold (Assessment Report 15144). A sample of a shear zone, 650 metres northeast of the Golconda showing, assayed 1.7 per cent copper, 22.0 grams per tonne silver and 0.2 grams per tonne gold (Assessment Report 15144).
