The Sher occurrence is located approximately 4.8 kilometres east of the Kennedy River at an elevation of about 820 metres.

The area is underlain by andesite and basalt of the Upper Tri- assic Karmutsen Formation, Vancouver Group. These are intruded by quartz monzonite, quartz diorite and diorite of the Jurassic Island Plutonic Suite. Feldspar porphyry, quartz feldspar porphyry and gabbro have also been observed in the area. Two major northwest trending lineaments transect the area.

Locally, copper mineralization occurs in a gossanous area comprised of porphyries that have intruded Karmutsen volcanics. The porphyries have been silicified, pyritized, sericitized, and saussuritized. A few calcite veinlets carrying a green mineral, possibly fuchsite, occur near the margin of the porphyry.

Another area, on the Sher 2 claim, located approximately 2 kilometres to the south- south west contains mineralized copper float and a soil geochemistry anomaly near two EM 16 anomalies.

In 1970 and 1971, Mount Washington Copper Co. Ltd. completed a program of soil, silt and rock geochemical sampling and a ground electromagnetic survey on the area as the Sher claim.
