The KL Gossan showing is underlain by Lower Jurassic andesitic volcaniclastic rock of the Unuk River unit of the Betty Creek Formation, Hazelton Group.

A 2 to 6-centimetre-thick quartz-calcite vein, poorly exposed in maroon volcaniclastics, hosts malachite and galena. The vein appeared to be fracture-controlled and have vuggy textures. A vein sample taken by Pretium Exploration in 2017 assayed 0.22 gram per tonne gold, 184 grams per tonne silver, and 8.12 per cent copper (Sample B067596, Assessment Report 37435). Although field observations indicated galena, sample analyses showed no elevation in lead.

WORK HISTORY

In 2017, Pretium Exploration conducted grass roots prospecting, sampling, and mapping on their Bowser property, mostly southwest and south of Bowser Lake. They collected 2901 rock and 429 silt samples (Assessment Reports 37435, 37443). Several new MINFILE occurrences are documented and a number previously documented occurrences were visited by Pretium.

In 2018, beyond the Brucejack mine area, Pretium continued to evaluate their surrounding 1250 square kilometres of mineral claims. The company carried out an 8000 metres drilling program along with mapping and prospecting.

As of September 2019, two drills were testing the high-priority A6 Zone Volcanogenic Massive Sulphide target, 14 kilometres northeast of Brucejack Mine, a third drill targeted a Volcanogenic Massive Sulphide system at the Canoe Zone, and a fourth drill targeted an intrusion related gold system at the Koopa Zone. Drilling earlier in the summer also focused on the Tuck and Lilliane zones, both epithermal gold system targets. To date, approximately 15,300 metres have been drilled, with drilling expected to continue through the end of September (Pretium Resources Inc., News Release, September 16, 2019).
