The Upper Noomas occurrence is located on a south flowing tributary of Noomas Creek, at an elevation of approximately 690 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, chalcopyrite veins in massive pyrite and marcasite(?) with associated garnet, covellite, melanterite and limonite are hosted along a Quatsino limestone-Karmutsen greenstone contact, near the granodiorite intrusion. In 1989, grab samples (NORs-1 and NORs-4) yielded up to 11.6 per cent copper, 102 grams per tonne silver, 0.185 per cent zinc and 56.2 per cent iron (Assessment Report 20092).

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. During 2013 through 2016, Graymont Western Canada Inc. completed programs of rock sampling and ground magnetic surveys on the area as part of the MQ, Nimpkish and Bonanza properties. This work was centered on the limestone occurrences in the area. In 2019, Ridgeline Exploration Services completed a 454.3 line-kilometre airborne magnetic survey on the area as the Nimpkish (Wolf) property.
