This copper showing outcrops on the west side of Grasshopper Mountain, 970 metres northeast of the confluence of Illal and Britton creeks and 11.5 kilometres due west of the town of Tulameen.
The occurrence is hosted in hornblende clinopyroxenite of the Early Jurassic Tulameen Ultramafic Complex, a zoned Alaskan-type intrusive complex. The showing is 100 metres east of the contact with metasediments and metavolcanics of the Upper Triassic Nicola Group.
A 210-metre wide band of coarse pyroxenite contains disseminated blebs of chalcopyrite and pyrite. Selected grab samples assayed between 1 and 1.5 per cent copper and trace to 2.4 grams per tonne gold (Assessment Report 9381, page 2).
