Capsule Geology

The Glacier occurrence is located at an elevation of approximately 1400 metres on a north-facing slope, west of the South Unuk River and approximately 10.3 kilometres northwest of Mount Pearson

The area is underlain by the Upper Triassic Stuhini Group, which consists of Upper and Lower divisions. The Lower division is dominantly sedimentary with undifferentiated, fine-grained, well-bedded rocks and coarser conglomerate layers, whereas the Upper division is dominantly volcanic and volcaniclastic with mafic to intermediate tuff and volcanic breccia, mafic porphyritic flows, felsic flows and flow breccia. The Stuhini Group is crosscut by a granitoid batholith and stocks of the Eocene Coast Plutonic Complex that display a range of rock types including medium- to coarse-grained biotite±hornblende granite and granodiorite with minor quartz diorite.

Locally, a quartz vein, 1.0 to 2.0 metres wide, hosts galena, chalcopyrite and pyrite mineralization. The vein strikes 100 degrees and dips 45 degrees north. The vein is located approximately 900 metres southeast and on strike of the BGS (MINFILE 104B 615) occurrence and appears to be part of the same ‘main’ shear zone.

Historical grab samples are reported to have yielded values of up to 6.54 grams per tonne gold and 364.8 grams per tonne silver (Mitchell, A.J., Prowse, N.D. [2020-06-08]: NI 43-101 Technical Report on the Doc Property).

In 2019, a 0.50-metre chip sample assayed 4.86 grams per tonne gold, 95.5 grams per tonne silver, 0.45 per cent copper and 0.19 per cent lead (Mitchell, A.J., Prowse, N.D. [2020-06-08]: NI 43-101 Technical Report on the Doc Property).

Work History

The area has been explored in conjunction with the nearby Doc (MINFILE 104B 014) occurrence and a complete regional exploration history can be found there.
