The Sam occurrence is located about 2.5 kilometres north of Haha Creek and approximately 54 kilometres northwest of the community of Germansen Landing.

The area is underlain by the Early Jurassic Hogem Plutonic Suite which consists of numerous intrusive bodies of distinct age. This complex varies in composition between gabbro, diorite, monzonite, syenite and alkali feldspar syenite.

At the showing, chalcopyrite, magnetite and specularite occur in diorite "veins" varying in width from 0.5 to 10 metres. In 1991, a rock sample (P29112) assayed 1.02 per cent copper (Assessment Report 21642). Mineralization is inferred to be disseminated porphyry-style similar to nearby occurrences.

Work History

In 1991, J.B. Reierson prospected the Sam claims and collected 12 soil and 12 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, Cathedral (094C 109, 181), Gail (094C 72, 133), Cirque, and Lake 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.
