Capsule Geology

The area is underlain by Upper Triassic Karmutsen Formation vol- canic rocks of the Vancouver Group. These are interbedded with, and overlain to the northeast by a northwest trending belt of Quatsino Formation limestone (Vancouver Group) known historically as the "lime-belt". The Vancouver Group rocks are in fault and/or intrusive contact to the northeast with intrusive rocks of the Juro-Cretaceous Coast Plutonic Complex.

On the Contact, skarn-type mineralization occurs along the contact of limestone and granitic intrusive rocks. The ore deposit is from 30 to 90 centimetres wide and consists dominantly of pyrrhotite with some quartz, chalcopyrite, garnet, epidote, hornblende and related silicates. At one point, four narrow parallel mineralized bands or zones occur within a thickness of 4.6 metres (Geological Survey of Canada Summary Report 1913).
