The Copper Standard North occurrence is located at an elevation of approximately 1070 metres on an east-facing slope, approximately 1.5 kilometres northwest of the north end of Crater Lake.

Regionally, the area is underlain by the Upper Triassic Nicola Group, which regionally consists of alkalic and calc-alkalic volcanics and intrusions of island arc origin, and which is the principal component of the Quesnel terrane in southern British Columbia (Geological Survey of Canada Maps 41-1989, 1713A). The area lies in the Central Belt or facies of the Nicola Group (after Preto, Bulletin 69). This belt of rocks mainly consists of subaerial and submarine, red or purple to green augite plagioclase porphyritic andesitic and basaltic flows, volcanic breccia and tuff, and minor argillites and limestone. The volcanics are intruded by bodies of comagmatic Upper Triassic to Lower Jurassic diorite to monzonite. The area is characterized by long-lived, primarily north-striking faults and related fracturing, which originally controlled intrusion emplacement. East-striking faults are subordinate, and commonly offset intrusive contacts.

Locally, a fractured and epidote-altered andesite hosts north-trending carbonate fractures, veins and stringers with chalcopyrite and malachite

In 1997, two grab samples (125866 and 125867) from a historical trench yielded 0.441 and 0.690 per cent copper, respectively, whereas a grab sample (125868) from a 0.5-metre-wide, high-grade fracture zone yielded 1.71 per cent copper and 0.120 gram per tonne gold (Assessment Report 25611).

Work History

The area has been explored in conjunction with the nearby Copper Standard (MINFILE 092HNE079) occurrence and a complete exploration history of the area can be found there. A historical trench is reported on the occurrence.
