The Westside porphyry copper showing is located approximately 8.2 kilometres southwest of Mount Warner, 148 kilometres southwest of Williams Lake, B.C.

The area is underlain by hornblende-biotite quartz diorite of the Upper Cretaceous Coast Plutonic Complex.

Locally, pyrite and chalcopyrite occur as disseminations, along fracture planes and within shear zones within chlorite-epidote altered quartz diorite.

Work History

During 2014 through 2019, Amarc Resources Ltd. completed programs of geological mapping, geochemical (talus fines, rock chip and stream sediment) sampling, 163.6 line-kilometres of induced polarization surveys, 1069 line-kilometres of airborne magnetic surveys and 18 157 metres of diamond drilling on the area as part of the IKE project. The majority of the drilling (15 455.34 metres in 26 holes) was completed on the IKE (MINFILE 092O 025) occurrence. Geological mapping around the WESTSIDE occurrence was conducted in 2014 (Assessment Report 35307), followed up by eight wild-cat exploration drill holes in 2017, as part of the Mad Major exploration target, and more mapping and geophysical assessment in 2018.
