The Sinker (Camp Creek) occurrence is located on high ground of the westward ridge of Mount Kotzebue.
The area lies within the Insular Belt of the Cordillera and is underlain mainly by volcanics and crystalline rocks and minor sediments. Andesitic to rhyodacitic lava, tuff and breccia of the Lower Jurassic Bonanza Group overlie an assemblage of sediments of the Paleozoic Sicker Group and basalts and minor carbonate and clastic sediments of the Upper Triassic Vancouver Group. The Bonanza volcanics are coeval with, or genetically related to granodiorite stocks of the Jurassic Island Plutonic Suite. These intrude all rocks.
Locally, disseminated chalcopyrite and fracture fillings of chalcopyrite with pyrrhotite in skarn-altered sediments of the Parson Bay Formation (Vancouver Group) are present. These are intruded by microdiorite and felsite dikes. The reports in Property File (092L 237-Ruf 41) refer to the mineralization as the "Central and West zones".
In 1989, a sample (KLA-44) assayed 0.68 per cent copper (Assessment Report 4730). In 2009, grab samples of mineralized skarn material returned values of up to 0.111 per cent copper (Assessment Report 31164).
Work History
In 1966, a small dip-needle geophysical survey and a geochemical survey were completed in the Camp Creek area. In 1970, Belvedere Mines completed programs of geological mapping and soil geochemical sampling. This work identified the Camp Creek (West) and Red Bluff zones. In 1973, Brinex optioned the property and completed a program of geological mapping and soil geochemistry.
In 1982, Bp Minerals completed a program of geological mapping and geochemical sampling on the area as the KI claims. In 1989, the claims were re-staked by Ron Biliquest and a prospecting program was completed.
In 2009, Centerfire Minerals acquired the property and completed programs of prospecting, geochemical sampling and ground geophysical surveys. In 2013, R.J. Bilquist completed a minor program of geological mapping and rock sampling on the area as the Klaskino property. The following year, Homegold Resources Ltd. completed an air photo geological interpretation program on the area as the Kluska 2 claim. During 2016 through 2019, R.J. Bilquist completed a minor program of geochemical (rock and silt) sampling and geological mapping on the Klaskino property.
