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

The Bigtime E 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 4-6 centimetre wide vein/shear zone mineralized with disseminated pyrite, chalcopyrite, and minor malachite staining on fractures is hosted in a green-grey, fine-grained crystal tuff of the Telkwa Formation. In 2009, a rock sample (B880644) assayed 1.78 per cent copper and 18.1 grams per tonne silver (Assessment Report 31410). Mafic tuff or diorite and quartz and carbonate veins have also been noted.

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 2.4 kilometres north, for details on the Bigtime E work history.
