The Ruth occurrence is located on the eastern side of the Kennedy River, across from Adit Creek.

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

A 0.5 metre wide quartz vein, exposed for 30 metres on surface, contains pyrite and chalcopyrite. The 55 degree striking, 75 degree southeast dipping vein occurs in porphyry. A small diabase dike accompanies the vein on the hanging wall and limestone outcrops within 3 metres. A sample assayed 1.9 per cent copper, 96 grams per tonne silver and trace gold (Minister of Mines Annual Report 1913).

The Black Bear claim was 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 1988, Golden Spinnaker Minerals completed a program of geological mapping, ground magnetic surveys and geochemical sampling. 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.
