The O.K. occurrence is located north of Dry Creek, approximately 1 kilometre north- north west of the creek mouth.

The area is underlain by quartz diorite of the Early to Middle Jurassic Island Plutonic Suite. Contact with volcanics of the Upper Triassic Karmutsen Formation (Vancouver Group) occurs just south of the occurrence. These plutonic rocks vary in composition from gabbro to quartz monzonite but are mainly granodiorite and quartz diorite.

The O.K. (Cub) vein varies in width from several centimetres to over 45 centimetres and may split or occur with nearby parallel veins. The vein, striking 100 degrees and dipping between 30 and 45 degrees to the north, is traceable along strike for 430 metres. The vein is not visible for much of this length but the sharply defined hanging wall is evident. The quartz vein is locally mineralized with sphalerite, pyrite and galena. The wallrock is sheared and altered and contains a little pyrite.

In 1982, a 37 centimetre sample assayed 6.10 grams per tonne gold and 92.23 grams per tonne silver (Assessment Report 11110). Previous sampling by B.C. Department of Mines (H. Sargent) in 1939, is reported to have yielded 96.04 grams per tonne gold and 473.3 grams per tonne silver across a 0.75 metre wide pyrite zone.

During 1972 through 1982, W. Guppy and Golden Hinde Mines completed programs of prospecting, rock and soil sampling, geological mapping and four packsack drill holes, totalling 20 metres, on the area by as the Cub and Nub claims.
