Capsule Geology

The Q32 occurrence is located at an elevation of approximately 1320 metres on a generally north-facing slope, approximately 5.2 kilometres south of the junction of the South Unuk River and Gracey Creek.

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 biotiteĀ±hornblende granite and granodiorite with minor quartz diorite.

Locally, a shear zone hosts quartz veining with pyrite, chalcopyrite galena mineralization.

Historical trenching on the vein is reported to have yielded up to 1.78 grams per tonne gold and 13.3 grams per tonne silver over 2.44 metres, while a nearby float sample yielded 241.89 grams per tonne gold and 526.1 grams per tonne silver (Mitchell, A.J., Prowse, N.D. [2020-06-08]: NI 43-101 Technical Report on the Doc Property).

In 2019, six rock samples, primarily of float, taken from the Q32 occurrence area yielded an average of 19.65 grams per tonne gold (up to 50.60 grams per tonne), 226.3 grams per tonne silver (up to 479.0 grams per tonne), 0.73 per cent copper (up to 2.07 per cent) and 10.6 per cent lead (up to 11.9 per cent; Mitchell, A.J., Prowse, N.D. [2020-06-08]: NI 43-101 Technical Report on the Doc Property).
