The Virginia vein is part of the "Main vein" system, of the Rossland mining camp, which forms a continuous well defined fracture system on a regional scale trending 70 degrees for a strike length in excess of 1.0 kilometre. The Virginia vein is a sulphide ore body which strikes east-west and dips steeply north and averages 7.6 metres in width.

The vein is hosted by the Rossland monzonite, an east-trending biotite-hornblende-augite monzonite stock. The stock intrudes augite porphyry and volcanic rocks of the Lower Jurassic Elise Formations, Rossland Group. The augite porphyry, known as the Rossland sill, intrudes the upper part of the Elise Formation.

Mineralization consists of pyrrhotite and chalcopyrite infilling fractures and/or faults. Gangue consists of altered wallrock with lenses of quartz and calcite. Pyrite occurs as crystals in the pyrr- hotite and as disseminations in the host rocks.

In 1899, 95 tonnes of ore were mined from the Virginia vein and 2395 grams gold, 1866 grams silver, and 943 kilograms copper were recovered.
