The Commander (L.960) occurrence is located north of Trail Creek and east of the community of Rossland, at an elevation of approximately 850 metres.
The area is underlain by quartz monzonite of the Early Jurassic Rossland Plutonic Suite, an east-trending stock comprised of a biotite-hornblende-augite monzonite. Syenite of the Middle Eocene Coryell Plutonic Suite invades the Rossland monzonite, which is crosscut by a variety of dioritic and lamprophyre dikes.
Locally, mineralization consists of disseminated coarse- and fine-grained pyrite, pyrrhotite and chalcopyrite. A black copper oxide, melanterite(?) and scheelite have been identified from dump samples on the property.
In 1915, disseminated sulphides from the monzonite host assayed 5 to 7 grams per tonne gold (Geological Survey of Canada Memoir 77, page 131).
The area has been explored since the late 1800s, with the Crown-granted mineral claims being staked in the 1890s.
During 1987 through 1990, programs of prospecting, geological mapping and ground magnetic surveys were completed on the surrounding area as the Arr claims of Charleston group property. Also in 1990, a ground electromagnetic survey was conducted on the area as the Pooch 1-3 claims. In 1998, Klondike Gold Corp. soil sampled the area as the Spitz 2 claim.
