Former Gunnar Mine Site Rehabilitation Project

The Government of Saskatchewan and the Government of Canada have signed a Memorandum of Agreement (MOA) to address the Cold War Legacy Uranium Mine and Mill Sites in Northern Saskatchewan. This agreement includes the rehabilitation of the former Gunnar mine site, located on the north shore of Lake Athabasca. Under the MOA, Saskatchewan Industry and Resources (SIR) has been assigned the responsibility to ensure that the project is carried out on behalf of the two governments. SIR has signed a contract with the Saskatchewan Research Council (SRC) to fulfill the role of project manager and designated agent to manage and perform the required environmental assessment requirements and rehabilitation activities. On 23 April 2007, SRC submitted a project proposal for Gunnar site rehabilitation. The proposal includes the following components:

  • Demolition of existing building, facilities and structures;
  • Appropriate disposal of materials resulting from demolition;
  • Installation of an appropriate cover on all or a portion of the exposed mill tailings;
  • Rehabilitation of existing waste rock piles;
  • Rehabilitation of additional risk(s) as warranted;
  • General site clean-up;
  • Re-vegetation of areas of the rehabilitated site as required; and
  • Appropriate monitoring during and after rehabilitation.
