The Nanaimo Lakes showing is located south of the Nanaimo Lakes forestry road, between Nanaimo Lakes.

The area is underlain by Upper Triassic Karmutsen Formation (Vancouver Group) porphyritic andesitic to basaltic rocks in contact with Paleozoic Sicker Group argillites and intruded by diorite of the Jurassic Island Intrusions.

The occurrence is underlain by Karmutsen Formation porphyritic basalt cut by numerous faults near the contact with argillite of the Sicker Group. Pits and trenches expose small quartz veins and veinlets in a fault zone in the basalt. Wallrock is schistose. The veins dip 45 degrees south. Mineralization consists of minor amounts of pyrite, chalcopyrite, bornite and magnetite.

During the years 1963 to 1966, Gunnex Ltd, carried out a regional mapping program with some limited prospecting and silt sampling they completed a list of all known mineral occurrencesin the area. In 1981, Manny Consultants completed a program of soil geochemical sampling on the Nanaimo claim.
