The Canon showing is located on the slopes of Mount Olsen, about 24 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.

A northeast trending mineralized quartz vein, averaging 5 centi- metres in width and up to 25 metres long, is hosted in diorite. The vein, which trends 040 degrees and dips 60 degrees southeast, occurs along a major fracture system. It contains masses and blebs of pyrite, pyrrhotite, sphalerite, and lesser chalcopyrite, covellite, malachite and azurite. Alteration of the diorite on either side of the vein include silicification and epidotization.

An 8 centimetre chip sample of the vein assayed 73.5 grams per tonne gold, 42.5 grams per tonne silver, 0.07 per cent copper, 2.26 per cent zinc and 0.076 per cent lead (Assessment Report 13875).

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.
