The Ben Bolt occurrence is located near the headwaters of the south fork of Glacier Creek, 6 kilometres east-northeast of Stewart.

The vein, carrying polymetallic mineralization, was periodically investigated between 1906 and 1955. In 1910 and 1912, 480 metres of underground workings were completed. In 1929-30, a program of prospecting was performed. In 2006, Auramex Resource Corp. completed a program of geochemical sampling on the area, under their Bear property.

The mineralized quartz breccia zone is hosted in argillite of the Middle Jurassic Salmon River Formation (Hazelton Group) near the southwest margin of a Tertiary(?) augite diorite stock. The argillite strikes northwest and dips gently southwest.

The occurrence is situated at the south end of the Portland Canal Fissure Zone. This zone of faulting and shearing trends north, dips steeply west and hosts a vein system that extends from the Victoria/Dandy occurrence (104A 067) on the north, through the Dunwell mine (103P 052) across Glacier Creek to this occurrence.

The showing consists of a 2.4 to 30 metre wide quartz breccia zone. The zone contains distinct quartz veins and lenses up to 1.8 metres width and outcropping along a length of 600 metres. The vein strikes northwest and dips 22 to 30 degrees southwest. A few subparallel, silicified porphyritic diorite dikes are associated with the vein.

Mineralization consists of disseminated pyrite, galena, sphalerite and minor chalcopyrite, pyrrhotite and arsenopyrite in a gangue of quartz and silicified argillite fragments. An intensely mineralized zone forms a 32 metre long ore shoot varying from a few centimetres to at least 3 metres in width and extending downdip for 15 metres. A 4.3 metre chip sample across the ore shoot assayed 2.4 grams per tonne gold, 193 grams per tonne silver, 15.01 per cent lead, 0.9 per cent copper and 3.16 per cent zinc (Geological Survey of Canada Memoir 32, page 38).

In 2018, an outcrop sample (X956809) from a 2-metre-wide quartz vein with massive sulphides hosted by brecciated mudstones assayed 10.8 grams per tonne gold, 56.8 grams per tonne silver and 1.2 per cent zinc (McCrea, J.A. [2020-10-20]: Technical Report on the Dunwell Property, Skeena Mining Division, British Columbia, Canada).

Work History

During 2017 through 2020, Singer Resources Inc. and American Creek Resources Ltd. completed programs of geochemical sampling, a 13.5 line-kilometre induced polarization survey and a 438.5 line-kilometre airborne magnetic and LiDAR survey on the area as the Dunwell property.
