The St. Eugene mine is located 1.5 kilometres south east of Moyie, east of Moyie Lake.

The deposit is hosted by quartzites and argillites of the Helikian Middle Aldridge Formation (Purcell Supergroup) and is contained within an east-west fracture zone, dipping 70 degrees south, which strikes across the axial plane of a large regional northeast plunging anticline. The St. Eugene mine is on the eastern limb of the anticline and the Aurora showing (MINFILE 082GSW023) is on the western limb across Moyie Lake.

The deposit consists of two important veins and a system of connecting veins which meet the main vein system at a low angle. Most of the ores occurred at or near such junctions in the form of irregular lenses. Very little displacement was noted along the vein as a whole and they are probably tensional fractures along the crest of a plunging anticline. It was reported that the sulphides (mainly pyrite, pyrrhotite and sphalerite) were slightly more abundant near the margins of the orebodies and that sphalerite showed no increase with depth. At the 305 metre level, the two main veins/fissures are 183 metres apart and converge downwards and towards the west.

Production from 1899 to 1929 totalled 1.5 million tonnes resulting in 182,690,658 grams of silver, 78,846 grams of gold, 113,034,479 kilograms of lead and 14,482,913 kilograms of zinc.

The deposit was recorded in 1893 by James Cronin, who was told of the ore by the Ktunaxa (Kootenai) people. St. Eugene Consolidated Mining Company conducted early development and in 1905 the mine was taken over by the Consolidated Mining and Smelting Company. In 1947, Saint Eugene Mining completed a program of geological mapping and a 10 line-kilometre ground magnetic survey on the area as the Moyie property. In 1990, Cominco completed a 16.5 line-kilometre ground electromagnetic survey on the area. In 2006, Saint Eugene Mining completed 697 line-kilometres of airborne combined magnetic and electromagnetic surveys on the area. In 2011 and 2013, Kootenay Silver completed programs of geological mapping, rock sampling, a 500 line-kilometre airborne magnetic survey and a 500 line-kilometre seismic survey on the area as the Silver Fox property.
