Westmoreland Mining LLC

At Westmoreland Mining, we take pride in being exceptional earth movers - driven by a commitment to safety, environmental stewardship, and operational excellence.

Founded in 1854, Westmoreland Mining is one of North America's oldest running companies. Headquartered in Lone Tree, Colorado, we've been a reliable partner in powering communities and industries for over 170 years.

Our numerous Operations stretch along the spine of the Rockies, from the Northern reaches of Alberta in Canada, down to San Juan, New Mexico in the USA. In lock – step with our communities and service providers, we oversee the operation and management of world – class surface mines, award winning reclamation programs and highly prospective industrial “hubs” being prepared for an exciting future. An unwavering commitment to safe, responsible mining practices has earned us industry recognition and multiple awards for safety, land restoration and community support.

Today, Westmoreland continues to build on a legacy of excellence while adapting to the evolving energy landscape, working hard to ensure that the land we mine is returned to an equal or better condition than we found it.

We are excited for the future and the opportunities to build on our rich history, traditions and culture, as we continue to find and provide solutions for North America’s wants and needs for generations to come.
