The North Wolf (CBL A zone) occurrence is located on the northeast side of Storey Creek, at an elevation of 870 metres.

The area is underlain by north striking carbonates and calcareous sediments of the Quatsino and Parson Bay formations overlying Karmutsen Formation tholeiitic basalts, all of the Upper Triassic Vancouver Group. Lower Jurassic Bonanza Group andesitic to rhyodacitic lava, tuff, breccia and minor sediments are coeval with, or genetically related to, granodiorite of the Nimpkish batholith of the Jurassic Island Plutonic Suite. Strong, regional north to northwest trending faults, often defining intrusive and lithological contacts, traverse the area.

Locally, a zone, greater than 50 metres in width, of semi to massive magnetite, chalcopyrite, sphalerite, pyrite and pyrrhotite in a garnet-diopside skarn and recrystallized limestone is exposed near a major intrusive contact and several small felsite dikes. The sulphide minerals occur as bands and disseminations within massive magnetite.

In 1989, a sample (W90-1) from a massive chalcopyrite-magnetite lens assayed 10.0 per cent copper, 0.269 per cent zinc and 114 grams per tonne silver. Other samples (WRS-1 and W90-2) of the disseminated mineralization assayed up to 3.82 per cent zinc and 0.253 per cent copper (Assessment Report 20092). In 1995, select samples assayed up to 20.8 per cent zinc, 10.3 per cent copper and 377 grams per tonne silver (Assessment Report 24207).

Work History

During 1989 through 2006, J.W. Laird completed programs of rock sampling and geological mapping on the area as the Nimpkish and CBL 1-10 claims. In 2019, Ridgeline Exploration Services completed a 454.3 line-kilometre airborne magnetic survey on the area as the Nimpkish (Wolf) property.
