Capsule Geology

The Lookout prospect area is underlain by andesitic volcanic rock of the Lower Jurassic Unuk River Formation, Hazelton Group.

In 2015, drilling in the Lookout zone was focused on testing surface geochemical anomalies located 500 to 700 metres west of the Brucejack fault. Holes SU-662, SU-663 and SU-664 intersected broad zones up to 49 metres long, with low-grade gold values. In Drillhole SU-663, a drill intersection of 21 metres assayed 0.58 gram per tonne gold and 2.41 grams per tonnes silver (Pretium Resources Press Release Oct.8, 2015). Hole SU-663 also yielded a 49 metre intersection assaying 1.31 grams per tonne gold and 1.58 grams per tonnes silver (Pretium Resources, Press Release, Oct.8, 2015).

Refer to West (104B 193) for details of related mineralization and an up to date common work history relating to the Brucejack project of Pretium Resources, which encompasses the Lookout zone.
