About CST COAL
CST Coal is a metallurgical coal mining company based in Grande Cache, Alberta, producing premium low-volatile coking coal for export to the international steel industry. As the operator of the Grande Cache Coal Mine, CST Coal resumed mining activities in 2018, building on the mine's legacy since its initial operations in 1970.
Our operations span a 4,900-hectare Mine Permit Boundary in the Smoky River Coalfield, with a focus on sustainable practices, including progressive reclamation. With a Coal Processing Plant and surface mining at the No. 8 Mine, we are committed to delivering up to 5.21 million tonnes of salable coal annually while preparing for future underground mining.
