The Raven Silver Project is located 390km northwest of the city of Helena and only 15km from Thompson Falls in Montana USA. The project consists of 27 mineral claims and hosts the historic Raven Silver Mine (formerly Copper Mask Mine) and Silver King Mine, within the Thompson River mining district.

These mines produced silver, copper, lead and zinc ores from a series of steeply dipping veins hosted in quartzite and argillite of the Ravalli Formation.

Mine production was intermittent through the late 19th century to the mid-20th century. Though no antimony was reported in the early 20th century production, Raven Mining Co. collected channel samples from several veins within the Raven Mine which were published by the Montana Bureau of Mines and Geology (MBMG) in 1963. The Project has no recorded modern exploration or drilling providing an exceptional opportunity for discovery. Access to the project is provided by the Thompson River public road running through the Project.

United States Antimony Corp. (USAC) own and operate a multi commodity processing facility and the Stibnite Hill mine 45km to the west of the project providing a pathway to future production.

The project’s proximity to the USAC processing facility (45km west) provides a distinct advantage. This existing infrastructure offers a potential processing route for future ores, significantly reducing the capital hurdles often associated with greenfield developments in the region.
