Capsule Geology

The Hanging Glacier occurrence area is underlain by bedded siltstone (turbidite) and well sorted arkosic wacke, greywacke and conglomerate of the Lower Jurassic Unuk River Formation, Hazelton Group. Area rocks have undergone pyrite-quartz-sericite alteration (Open File 1988-4).

The property was first noted in 1966 by Silver Ridge Mining (Assessment Report 836).

In 1980, Esso reported minor quartz-calcite-barite veins occur within an area of about 61 by 122 metres (Bridge et al, 1981). Electrum was found in association with barite at one location. Samples at the time contained erratic gold and silver values.

Refer to West (104B 193) for details of the Sulphurets-Brucejack property which encompasses this showing.

Several traverses were made in the Hanging Glacier area in 1988 by Sulphurets Lake Gold when numerous rich veinlets known to exist were revisited (Assessment Report 18564). The veins found were all small, in the order of a few centimeters wide and a few metres long. No area has yet been located where these veinlets could be bulk mined.

Also reported in the vicinity are quartz-carbonate stringers plus or minus sphalerite, tetrahedrite, galena, chalcopyrite, and pyrite (Personal Communication, J.M. Britton).
