The Ten (Main) occurrence is located about 4.5 kilometres south of Tenakihi Lakes and approximately 63 kilometres northwest of the community of Germansen Landing.

The region is underlain by the Early Jurassic Hogem Plutonic Suite which consists of numerous intrusive bodies of distinct age. Rocks vary in composition between gabbro, diorite, monzonite, syenite and alkali feldspar syenite (Fieldwork 1991).

In the Ten Main grid area, the dominant rock type is monzodiorite. It is intruded by small plugs and dikes of other intrusive types. Local minor pyrite and chalcopyrite occurs in the monzodiorite as disseminations and fracture fillings. Copper values as high as 0.42 per cent were reported; gold values were below 0.065 gram per tonne (Assessment Report 21419). In 1991, a quartz vein float sample containing malachite stain, disseminated chalcopyrite, bornite and molybdenum assayed 0.11 gram per tonne gold and 0.53 per cent copper (Assessment Report 21419).

Work History

In 2009-10, C.O. Naas examined the provincial Regional Geochemical Survey data and British Columbia MINFILE which led to the staking of the Thane Creek property tenures. A comprehensive compilation of historical exploration work was undertaken and identified four areas that indicated excellent potential for copper-gold mineralization. In 2010, a property visit was carried out and explored three of the target areas identified by the compilation program. Exploration consisted of geochemical sampling with collection of 10 silt samples and 69 rock samples. In 2012, Thane Minerals Inc. carried out exploration at multiple areas on the Cathedral property including the Tenakihi (094C 071), Link (094C 123), Osilinka (094C 050), Cathedral (094C 109, 181), Gail (094C 072, 133), Cirque (093N 093), and Lake (094C 188) zones. Exploration consisted of silt sampling, soil and talus fine sampling (contour and gridded), rock sampling, and geological mapping. A total of 36 silt samples, 785 soil and talus-fine samples, and 749 rock samples were collected. Approximately 1525 hectares were geologically mapped at 1:10,000 scale. Analyses of soil and talus fine samples and selected rock and silt samples have been carried out by x-ray fluorescence (XRF).

In 2020, Interra Copper Corp. completed a program of geological mapping, geochemical (rock, soil and stream sediment) sampling and a 14.0 line-kilometre induced polarization survey on the area as the Thane property.
