The Bear Hill West occurrence is located approximately 5 kilometres north of the west arm of Takla Lake, and approximately 104 kilometres east of Hazelton.
The region is underlain by Lower Cretaceous Skeena Group volcanics uplifted into conglomerate and sandstone of the Cretaceous Tango Creek Formation (Sustut Group) and downfaulted blocks of Eocene Ootsa Lake Group subaerial dacitic to basaltic porphyritic flow rocks and coarse to fine fragmental volcaniclastic rocks. The Ootsa Lake Group volcanics are exposed as a series of topographic knolls aligned along a 20-kilometre long, north-trending extensional structure crosscut by northwest- and northeast-trending faults. Middle Jurassic Hazelton Group (Smithers Formation) marine sedimentary and volcanic rocks are uplifted to the north, partially due to faulting.
The area is underlain by volcanic assemblages ranging from andesite to rhyolite. Sulphide mineralization, chiefly pyrite with rare traces of chalcopyrite and arsenopyrite, is sparse and confined to fracture planes. Sericite alteration has been found in some samples.
Work History
The area has been explored in conjunction with the nearby Bear Hill (MINFILE 093M 137) occurrence and a complete exploration history can be found there.
In 2012, an exploration program by Copper Point Mining Corp on its Tacla claim comprised prospecting and limited rock and soil sampling. A total of 53 soil and 16 rock samples were collected. Sampling of the Bear Hill West occurrence yielded values of up to 36 grams per tonne silver, 0.74 per cent copper, 0.82 per cent lead, 0.254 per cent zinc and 0.79 per cent barium (Samples 43253 and 43252, Assessment Report 34072), though B-horizon soil samples of the knoll and sampling of surrounding areas did not return any anomalies.
