Capsule Geology

The Boulder showing occurs within the hornfelsed contact between the Cenozoic Coast Plutonic quartz diorite intrusive and the Upper Triassic Stuhini Group sediments.

In 1911, a large body of low grade ore, containing copper, gold, silver and lead mineralization, was reported to occur about 8 kilo- metres north of the Alaska-British Columbia border on the east side of the Unuk River. Host rocks consist of Upper Triassic (?) hornfelsed sediments comprised of altered slates, argillites, quartzites with minor limestone and breccia. The sediments are crosscut by several intrusive dykes of variable widths. Abundant disseminated pyrite occurs throughout the sediments.

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Quillian claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.
