The Bigtime C occurrence is located just southwest of Ominicetla Creek about 200 kilometres northwest of the community of Fort St. James.

The Bigtime C showing area is underlain primarily by the Lower Jurassic Telkwa Formation (Hazelton Group) consisting of a sequence of subaerial to submarine calc-alkaline island arc volcanic and sedimentary rocks. Cretaceous to Eocene volcanic and sedimentary rocks of the Sustut Group are also present. The Telkwa Formation rocks are intruded by small plugs of quartz and hornblende feldspar porphyry of unknown age and a large plug of biotite hornblende diorite of Late Jurassic age.

A fine-grained, grey crystal tuff of the Telkwa Formation contains disseminated pyrite and chalcopyrite with minor malachite staining and appears to be associated with a shear zone. In 2009, a rock sample (B880737) assayed 0.94 per cent copper (Assessment Report 31410).

In 2009, Amarc Resources Ltd. completed a program of geological mapping, prospecting, rock (184) and soil (519) sampling, and an induced polarization survey (11.7 kilometres).

See Lion (093M 146), located 2 kilometres north, for details on the Bigtime C work history.
