Rosebud Mine

Located near Colstrip, Montana, in the northern Powder River Basin, the 25,000-acre Rosebud Mine produces nearly 6 million tons of coal annually from approximately 7,300 active mining acres. Production is supplied under a long-term contract to the adjacent Colstrip Power Station, one of the region's most efficient and reliable baseload power facilities. Specifically designed to utilize coal from the Rosebud seam, the plant provides affordable, dependable electricity to Northwestern utilities, serving more than 1 million homes and businesses.

Environmental stewardship is a core part of Rosebud's operations. Working in close partnership with federal and state regulatory agencies, the mine implements progressive reclamation practices throughout the mining lifecycle, including topsoil salvage and redistribution, backfilling, regrading, drainage construction, revegetation, and long-term environmental monitoring. These efforts have resulted in more than 16,000 acres being reclaimed in various stages, with reclaimed land successfully returned to productive uses such as grazing, agriculture, and wildlife habitat. Rosebud has also achieved the full bond release of the 1,395-acre Area E Permit, allowing the land to be returned to its original owners for productive agricultural use.

Rosebud maintains a longstanding partnership with the Northern Cheyenne Tribe, built on collaboration and mutual respect. The mine supports the community through a dedicated full-time liaison, preferential hiring opportunities, employee transportation, assistance for tribal law enforcement, donations of locally raised meat to the senior center, and a college scholarship program.

For decades, Rosebud has safely delivered reliable energy while earning numerous federal, state, and industry awards recognizing its commitment to operational excellence, environmental stewardship, and workplace safety.
