The former Gunnar Mine site is located on the north shore of Lake Athabasca, approximately 25 kilometres southwest of Uranium City.
The mine operated from 1955-1963 and officially closed in 1964 with little to no decommissioning. During operation, the Gunnar Site consisted of:

- Two acid plants
- Uranium processing buildings
- A community (including a number of residential, public, administrative and technical buildings)
- Approximately 4.4 million tonnes of tailings
- Approximately 2.2 to 2.7 million tonnes of waste rock
Demolition activities to-date have included:
- Extensive asbestos abatement of buildings
- Demolition of more than 80 buildings and structures
- Cleaning up site debris
- Constructing a barrier around the open pit
- Removing physical, chemical, radiological and biological hazards
- Completing asbestos abatement and demolishing remaining buildings, facilities and structures
- Disposing demolition debris
- Installing an appropriate cover on the exposed mill tailings
