Capsule Geology

The Copper Creek 18 occurrence is located on upper Kinman Creek, approximately 7 kilometres southeast of the creek mouth of Nimpkish Lake.

The area is underlain by granodiorite of the Nimpkish batholith which is part of the Jurassic Island Plutonic Suite. The batholith intrudes Upper Triassic Vancouver Group rocks comprised of Karmutsen Formation volcanics and Quatsino Formation carbonates as well as the overlying Lower Jurassic Bonanza Group.

The occurrence comprises 23 metres of quartz- pyrite-chalcopyrite-molybdenite mineralization in a narrow shear zone cutting sericite-kaolinite altered granodiorite. Pyrite and chalcopyrite also occur in a quartz vein stockwork and are disseminated through the intrusive (Geological Survey of Canada Summary Report 1929, page A129 and Showing number 17 on Figure 6).

About 30 metres downstream from the occurrence is a large rusty outcrop of coarse pyrite in the creek bed, measuring 3 by 10 metres which hosts chalcopyrite and molybdenite in a quartz-sericite gangue.

There are other small showings of copper, zinc and molybdenite along the creek.

Work History

In 1928, E.L. Kinman and Associates discovered the main showings. In 1929 and 1930, Cominco optioned the tenures and completed surface trenching and twenty diamond drill holes, totalling 2010 metres on the area. In 1966, Empire Development completed a program of ground geophysical surveys and geological mapping on the area as the Alpha, Hazel and Pie claims, Kinman property. In 1998 and 1999, Doublestar Resources completed programs of prospecting and ground geophysical surveys on the area as the 2Star claim group. In 2010 and 2012, Selkirk Metals completed programs of prospecting and rock sampling. In 2016 and 2018, Selkirk Metals Corp. completed programs of geological mapping and geochemical (rock and soil) sampling on the area as the 2 Star property.
