The Bear occurrence is located on a hill over looking the Kennedy River to the east, approximately 5 kilometres north of the river mouth on Kennedy Lake.

Karmutsen Formation volcanics of the Upper Triassic Vancouver Group are intruded by the Early to Middle Jurassic Island Intrusions consisting of granodiorite to quartz diorite. The Karmutsen rocks consist of andesitic to basaltic flows, tuffs and volcaniclastics. West- north west trending fault/shear zones of Tertiary age cut the rocks.

The Bear shear zone is an east trending 30 metre wide hanging wall splay fault which forms the contact between andesite and quartz diorite. Within the shear zone the volcanics are intensely brecciated and locally silicified. Clay and chlorite form the alteration assemblage within the shear zone halo in quartz diorite. Chloritization and silicification mark the intrusive within the shear itself.

The Subway adit, driven into quartz diorite on the Cinnamon Bear Crown grant (Lot 294), follows the 85 degree striking, 50 degree northwest dipping footwall quartz vein along the footwall of the shear zone. The vein, pinching and swelling from 50 to 300 centimetres in width, contains pyrite, arsenopyrite, pyrrhotite, sphalerite and gold. A 70-centimetre chip sample across the vein assayed 17.5 grams per tonne gold and 10.3 grams per tonne silver (Assessment Report 11940). Four hanging wall splays occur over a strike length of 27 metres which averaged 10.66 grams per tonne gold over a 1 metre width (Henneberry, 1987).

The Black vein occurs on the hanging wall of the Bear shear zone, 75 metres west of the adit. The vein is up to 3 metres wide and locally contains massive pyrrhotite and black sphalerite with lesser chalcopyrite and pyrite. Wall rock alteration within the quartz diorite host consists of a 50 to 100 centimetre halo of chlorite and argillic bleaching. A 4.37 tonne bulk sample assayed 9.6 grams per tonne gold (Henneberry, 1987).

A zone of quartz veinlets and stringers (Stockwork showing) outcrops 250 metres east of the adit.

Probable and possible reserves are estimated at 160,000 tonnes grading 17.4 grams per tonne gold. This includes reserves from the adjacent Shack vein (092F 045) and Elite vein (092F 051) occurrences (George Cross News Letter No.38, 1989).

The claims were originally staked in the period around 1899 to 1902 and owned by T.O. MacKay. In 1938, the claims were sold to Kennedy Lake Gold Mines. In 1984, Rich Lode Gold Corp. completed a program of geochemical sampling and geological mapping on the area. In 2009 and 2010, G4G Resources Limited completed a program of prospecting and remote sensing, consisting of spectral analysis and synthetic aperture radar analyses, on the area as the G4G property.
