The Le Roi claim was reportedly developed by a Spokane company, the Le Roi Mining & Smelting Co., from 1891. The Le Roi Mining Company, Limited, acquired the Le Roi and Black Bear claims in 1898 and the mine operated continuously until it closed in September 1910. The property was acquired by Cominco in 1911.
The vein system is hosted by the Rossland monzonite which is comprised of a biotite-hornblende-augite monzonite stock that intrudes augite porphyry of the Rossland sill. The Le Roi vein was formed by mineralization replacing wallrock along well defined fractures and by filling fractures and faults with pyrrhotite and chalcopyrite. The gangue consists of altered host rock with lenses of quartz and calcite. Actinolite forms rosettes of silky green needles between chalcopyrite and pyrrhotite. Minor pyrite occurs as well formed crystals in the pyrrhotite and as disseminations in the host rock. Garnet crystals are associated with the pyrrhotite and chalcopyrite which occur in fractures with quartz.
Native silver has been reported in pyrrhotite rich ore from the Le Roi central zone. It occurs as blebs along the grain contacts of pyrrhotite and at the contacts of pyrrhotite with magnetite and gangue. Small grains of a silver bearing mineral, probably stromeyerite, with heavy surface stain are associated with the silver.
