Mining Methods at Hidden Creek Mine

Anyox, where the Hidden Creek mine of the Granby Consolidated Mining, Smelting and Power Company is located, is situated on an excellent deep-water harbour in Granby bay, at the head of Observatory inlet, about 600 miles from Vancouver and 90 miles north of Prince Rupert. Anyox is the Indian name for the little stream which empties into Granby bay, and means 'hidden creek'. The Ore-Bodies The ore is a replacement deposit and occurs at and near the contact between argillites and a later intrusive greenstone. This contact locally has a general north-and-south trend, an irregular westerly dip, and in the vicinity of the ore-bodies there has been intense folding, accompanied by faulting. The mineralizing solutions supposedly were derived from the Coast Range granite batholith, distant one to two miles to the east and north. The whole area is cut by many dykes of varying widths, which seem to have had but little part in the ore deposition.
