Quick facts

  • The former Gunnar Legacy Uranium Mine site was operated by Gunnar Mining Limited from 1955 to 1963, in northern Saskatchewan. The site was officially closed in 1964 with minimal decommissioning.
  • The site consisted of open and underground mine pits, three mine tailings deposits covering over 70 hectares of land, and waste rock piles. Management of the site later became the responsibility of the Province of Saskatchewan.
  • The removal of the hold point on the existing Waste Nuclear Substance Licence allows the SRC to carry out remedial activities as part of phase 2 of the remediation project.
