Capsule Geology

The Iron Horse mine 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 kilometre. The Iron Horse vein strikes east and dips 60 degrees north. The vein is hosted by the Rossland monzonite, an east-trending biotite- hornblende-augite monzonite stock. The stock intrudes siltstone, volcanics and augite porphyry (known as the Rossland sill) of the Lower Jurassic Elise Formation, Rossland Group.

Mineralization consists of pyrrhotite and chalcopyrite infilling fractures and/or faults. Gangue consists of lenses of quartz and calcite. Pyrite occurs as crystals in the pyrrhotite and as dissemi- nations throughout the host rock. Magnetite occurs as pseudomorphs of hematite.

In 1903, 27 tonnes of ore were shipped and 746 grams gold and 272 kilograms copper were recovered.

Refer to the Le Roi deposit (082FSW093) for further details of the Rossland mining camp and the Main vein system.
