Port Radium Mine.

Port Radium Mine is located on the eastern shore of Great Bear Lake, 440 km north of Yellowknife and east of the Dene community of Déline. The site was first mined in the 1930s for radium used in medical research, then for uranium in the 1940s and 1950s to make nuclear weapons and for nuclear power. The site was then mined for silver until 1982 when it was decommissioned. The site was reassessed in 2000 due to community concerns regarding silver, copper and uranium in soils and surface water on the site, as well as elevated gamma radiation associated with the waste rock.

Joint work conducted by AANDC and Déline resulted in a Final Report on Action Plan Activities released in 2005. A Port Radium Remediation Plan was then compiled by a joint process under the Canada-Déline Uranium Table leading to a decision to complete remediation work during the 2007 summer season.

During 2006-2007 water quality and state of the environment monitoring continued, a land use permit and Waste Nuclear Substance Licence were obtained, a capacity-building plan was developed, basic training took place with Déline community members and a contract was awarded for the remediation work.

Site remediation started in the winter of 2007 and was finalized in the spring of 2009.
