This community information site has been established to provide timely and relevant information following a breach of a containment pond at the Obed Mountain Mine.


On April 28, 2014, Westmoreland Coal Company (“Westmoreland”) and Sherritt International Corporation (“Sherritt”) concluded a sale transaction that had been planned since early 2013.

Westmoreland has acquired Sherritt’s coal assets, including Coal Valley Resources Inc. (“CVRI”), which owns and operates Obed Mountain Mine (“Obed”). CVRI, under Westmoreland, will continue to own and operate Obed.

CVRI is currently working with expert consultants carrying out monitoring and remediation activities for the Obed release. While no longer the owner and operator of CVRI and Obed, Sherritt retains the ultimate responsibility for all commitments and obligations resulting from the release at Obed, including monitoring and remediation activities and addressing Aboriginal and community concerns, and is working closely with CVRI and Westmoreland on these issues.

All future updates will be issued by CVRI.

Operations at the Obed Mountain Mine were staged-down in November 2012 in response to low coal prices. There are currently no plans to resume active mining and processing operations.

Since November 2012, Obed has been undergoing reclamation to restore previously mined areas to permanent vegetation, lake development and forest . Reclamation is an ongoing process that all mines, including active sites, undertake as a normal and progressive component of their operations. As of December 31, 2013, approximately 644 hectares, or 34% of the total mine area, had been reclaimed and converted to permanent vegetation, lake development and forest.
