In November 2011, Ambre Energy assumed 100 per cent ownership of the Big Horn coal deposit in Wyoming, USA.

Located in the Northern Powder River Basin in Sheridan County, Wyoming, a mine operated at the Big Horn site from 1944 until 2000, producing up to 4.1 million metric tons of coal per year at its peak.

While the Big Horn deposit is not currently being mined, it has significant remaining resources. Estimates indicate a total of more than 450 million metric tons of coal across Ambre Energy’s Rosebud and Big Horn deposits are ready for development with appropriate approvals.
