Background

The Mount Nansen Mine is a former gold and silver mine. The property is located 60 km west of the Village of Carmacks and is within the traditional territory of the Little Salmon/Carmacks First Nation.

In 1999, the mine owner, BYG Natural Resources Inc. (BYG), was unable to meet the requirements of the water licence and, as a result, ceased its mining operations. Immediately after production shutdown, BYG appointed a receiver to the site. 

In July 1999, the receiver abandoned the property, leaving a significant environmental liability. At the time, the Government of Canada took control of the site and began implementing care and maintenance operations at the site.

In 2003, the Devolution Transfer Agreement (DTA) was implemented.  Under the DTA, the Government of Yukon became responsible for care and maintenance of the property along with leading the development and implementation of a remediation plan.

The financial responsibility for the site continues to reside with the Government of Canada who provides 100 per cent of the funding for care and maintenance operations as well as for the development of a long-term remediation (closure) plan.

Both care and maintenance and remediation planning are to address short and long term risks at the abandoned contaminated site which may pose a risk to human health and safety and the environment.

Care and maintenance activities and remediation planning are unique to each abandoned mine site. For further details, visit Mount Nansen’s care & maintenance or remediation tabs on this website.
