The Col West occurrence is located at an elevation of approximately 1140 metres, on a northwest-facing slope, east of the Klawli River and approximately 5.5 kilometres southwest of 'Adade Yus Mountain.

Regionally, the area is underlain by undivided volcanic rocks of the Lower Jurassic Chuchi Lake Succession (Takla Group) and quartz monzonitic to monzogranitic intrusive rocks of the Lower Jurassic Hogem Plutonic Suite.

Locally, a monzodiorite cut by a crowded porphyry monzonite dike hosts blebs and disseminations of chalcopyrite within the dike and as biotite-chalcopyrite veinlets and localized quartz-chalcopyrite veins, up to 10 centimetres wide.

In 2014, two outcrop grab samples (2086903 and 2086902) yielded values of 0.757 and 0.812 per cent copper, 0.006 and 0.005 per cent molybdenum with 0.073 and 0.153 gram per tonne gold, respectively (Assessment Report 35327).

Another zone of mineralization, poorly defined and located, and comprising a showing of bornite, is reported on the east bank of the Klawli River, west of the previous zone of mineralization.
