The Specogna Copper showing is located on the north side of the Nanaimo River.
A major northwest trending fault separates volcanics of the Upper Devonian McLaughlin Ridge Formation (Myra Formation), Sicker Group with basalts of the Upper Triassic Karmutsen Formation, Vancouver Group. The basalts are overlain by sandstone and conglomerate of the Cretaceous Nanaimo Group. The rocks are cut by feldspar porphyry of the Tertiary Mount Washington Intrusive Suite (Labour Lake Pluton), previously Catface Intrusions (Personal Communication - Nick Massey, May 1990).
Chalcopyrite, pyrite, bornite and sphalerite occur in lenses, pods and stringers in sheared and altered Karmutsen pillow basalts. The mineralized shear zone measures 60 by 15 metres, strikes 175 degrees and dips 80 degrees east. Quartz, calcite and chlorite are the main gangue minerals. A grab sample assayed 15.8 per cent copper, 481 grams per tonne silver, 2.02 per cent zinc and 0.9 grams per tonne gold (Assessment Report 10302). A 1.1 metre drill intersection assayed 2.14 per cent copper, 9.6 grams per tonne silver and 2.5 grams per tonne gold (Assessment Report 10996).
