The Wedge occurrence is located at an elevation of approximately 1230 metres on the steep south slope of the Bouleau Creek Valley and approximately 25 kilometres west of Vernon.

Regionally the area is underlain by volcanics, mudstone, siltstone, shale and fine clastic sedimentary rocks of the Devonian to Triassic Harper Ranch and(?) Nicola groups, which are intruded by Middle Jurassic granitic rocks of the informally named Terrace Creek batholith. Eocene Coryell quartz latite porphyry to syenite plugs and dikes intrude the igneous and sedimentary rocks, and volcanic rocks of the Eocene Penticton and Kamloops groups overlie them.

Locally, quartz veins within a foliated Middle Jurassic granodiorite host gold and silver mineralization. Numerous quartz veins and veinlets, sometimes forming stockworks, carry native gold and/or electrum. The precious metal veins have a very fine grained saccharoidal texture with local colloform chalcedonic banding. The veins are narrow and discontinuous.

Calcite, agate and jasperoid occurring as lenses, irregular masses and thin veins in porphyritic andesite are also reported in the area.

In 1991, a sample (RX-046971) of quartz vein material from outcrop yielded up to 3.47 grams per tonne gold, whereas another sample (RX-049649), taken from a quartz vein located up slope to the southwest at an elevation of approximately 1420 metres, assayed 3.65 grams per tonne gold and 5.5 grams per tonne silver (Assessment Report 21877).

During 1988 through 1991, Chevron Mineral Ltd. completed programs of soil sampling and geological mapping on the area as the Boul 1-5 claims. Also in 1989, Antelope Resources Inc. prospected the area as the Moby 1-10 claims. In 1999 and 2000, Discovery Consultants completed ground magnetic and electromagnetic (VLF) surveys on the area as the Wedge 1-8 claims.
