The Inez and Gwen claims are located adjacent to Marcel Creek, approximately 11.5 kilometres north of Keremeos.

The area is underlain by medium-grained biotite-quartz monzonite of the Upper Triassic Similkameen Batholith, which intrudes Pennsylvanian-Permian volcanic and sedimentary rocks of the Shoemaker and Old Tom Formations.

Locally, an iridescent blue-grey weathering quartz-diopside skarn is overlain by a buff- coloured orthoquartzite and massive greenstone with minor hornfels. The succession appears to dip gently southwest with a maximum surface strike of approximately 80 metres. Sericite and limonite alteration occurs along the fault that separates the intrusive from the skarn.

Mineralization consists of coarse-grained powellite-scheelite and finer-grained scheelite crystals occur in the skarn and to a lesser extent in the overlying quartzite. Molybdenite and chalcopyrite are also noted in the skarn and flakes of molybdenite occur in the quartz monzonite.

The showing was first discovered by B.E. Williams of Keremeos in 1953 and worked as the Williams claims. Twelve pits and trenches were completed at this time. In the 1960’s, Kelowna Mines Hedley completed an adit on the showing. The claims were acquired by C.I. Brett in 1970 with several exploration programs being completed over the next decade. In 1979, sampling of old trenches returned values up to 0.44 per cent WO3 (Assessment Report 7804).
