What is the proposed project?

Montem Resources Alberta Operations Ltd. is proposing to restart and expand mining operations at the Tent Mountain Mine, an open-pit coal mine located 16 kilometres west of Coleman, Alberta that stopped operating in 1983. As proposed, the Tent Mountain Mine Redevelopment Project would expand the original mine pits to allow for the production of 4925 tonnes per day of raw coal used for steelmaking, over a 14-year mine life. The project would also include a coal handling and processing plant near the mining area and a rail loading facility located next to Provincial Highway #3 (Crowsnest Highway).
