The Olsen showing is located on Mount Olsen, 25 kilometres southeast of Port Alberni.

Tholeiitic basalts of the Upper Triassic Karmutsen Formation (Vancouver Group) are intruded by diorite to quartz diorite and minor feldspar porphyry of the Early to Middle Jurassic Island Plutonic Suite (Corrigan Creek pluton). An intra-formational layer of limestone and narrow band of dacite occur within the volcanics. A northeast trending joint or fracture system cuts all rock types. Diorites of the Early to Middle Jurassic Island Intrusions occur to the west.

Locally, a 600 metre long zone hosts disseminated and stringer pyrrhotite, pyrite and minor sphalerite, magnetite and chalcopyrite and occurs in basalt of the Upper Triassic Karmutsen Formation (Vancouver Group). The basalts are locally altered to chlorite and epidote-saussurite.

Samples assayed up to 0.08 per cent copper (Assessment Report 13857).

Between 2006 and 2008, the area immediately north was prospected by D.J. McLelland as the Les claim. In 2007 and 2008, Auracle Geospatial Science Inc. completed geophysical programs of spectral analysis and gamma ray surveys. In 2008, a spectral analysis program was completed on the area as the Crystal 1 and 2 claims.
