The Cenozoic Coast Plutonic Complex, comprised of quartz diorite, granite and granodiorite, intrudes Upper Triassic Stuhini Group sedi- ments exposed on the east side of the Unuk River. The sediments are hornfelsed near the contact and host abundant disseminated pyrite.

The Gold Run showing, occurs along Boulder Creek (also called Geking or Genking), within granitic rocks of the Coast Plutonic Com- plex. The showing consists of a narrow gold-bearing quartz vein mineralized with pyrite, galena and sphalerite (Minister of Mines Annual Report 1935, p. B10).

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.
