The Gold Boulder area is underlain primarily by quartz-biotite gneiss (metamorphosed sediments belonging to the Upper Triassic Stuhini Group). These commonly contain quartz veinlets, generally parallel to foliation. The southern edge of the property is underlain by granodiorite of the Coast Plutonic Complex.

In 1989, a grab sample of coarse-grained granodiorite from the Gold Boulder property, containing bands up to 5 centimetres wide with 3 to 5 per cent disseminated pyrite, yielded 3.76 grams per tonne gold and 0.49 per cent copper (Sample KZR 58, Assessment Report 19702). A grab sample of quartz-biotite gneiss, with disseminated pyrite, pyrrhotite and chalcopyrite and containing numerous 2 to 3 centimetre quartz veinlets, yielded 0.18 gram per tonne gold, 54.86 grams per tonne silver, and 1.42 per cent lead (Assessment Report 19702).

Work History

In 1987, a very limited silt sampling survey was conducted on the Gold Boulder property. Five samples were collected from north-flowing tributaries of Boulder Creek. These creek drain Coast Plutonic intrusions and small portions of the Stuhini strata. Sample results were disappointing.

The 1989 exploration program by Canadian Cariboo Resources Ltd on their Gold Boulder property consisted of helicopter-supported reconnaissance prospecting, geological mapping, and geochemical sampling. A total of 4 rock, 3 stream silt, and 4 heavy mineral samples were collected.

In 1990 Canadian Cariboo collected 2 rock float samples and 1 rock grab sample in conjunction with a stream sediment survey in the southeastern sector of the Gold Boulder property. These yielded weakly elevated values for gold, copper and silver.

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.
