The HC occurrence is located about 77 kilometres southeast of the community of Dease Lake.
The area is underlain by Upper Triassic-Lower Jurassic coarse bedded tuffs and agglomerates. The showing consists of a narrow shear vein varying in width from 0.6 to 1.5 metres. It strikes north, dips vertically and its length has been reported at up to 213 metres. A 1971 drillhole intersected coarse grained fragmental lava containing 6 millimetre-wide stringers of fine chalcocite with assays yielding 0.2 per cent copper and a trace of silver over 30 centimetres (Assessment Report 3237). A grab sample of chalcocite-rich vein material taken in 1971 yielded 3.26 per cent copper and 20.57 grams per tonne silver (Property File - Chisholm, 1971).
In 1983, Orsina Resources examined a showing in the same vicinity as the HC (West showing) consisting of bornite, chalcocite, malachite and chrysocolla hosted by vesicles and fractures in andesite flow tops (Assessment Report 12292, page 6). It is not clear whether the Orsina showing is the same as the HC. In 1969, Pelly Copper conducted a geological survey and first described the HC showing as the No. 1 zone. In 1971, Empire Metals covered this ground with the Bold 3 claim and prospected this showing as the West zone. They conducted an airborne magnetic survey over greater that 10,000 hectares and drilled one hole.
In 2008, a program of prospecting was carried out on the Sky claim held by D. McInnis.
