The Black Lion showing is located approximately 20.5 kilometres southeast of Port Alberni. The mineralization is related to the Black Panther mine (092F 084) about 1/2 kilometre to the northwest.

In the area, a north striking fault separates andesites of the Devonian Duck Lake Formation (Sicker Group) diorite of the Early to Middle Jurassic Island Plutonic Suite.

Pyrite and galena occur in quartz veins within a 0.25 to 2.8 metre wide carbonate altered shear zone within andesite and diorite. The veins are 30 to 50 centimetres wide over a 53 metre long zone which strikes north and dips 75 degrees east.

In 1987, a shear zone was sampled by Candorado Mines Limited and assayed 1.71 grams per tonne gold over 4 metres (Assessment Report 17235).

In 2005, Plateau Resources acquired the property and prospected the area the following year as BP claims.
