Proposed nuclear facility – Patterson Lake South Project
Fission Uranium Corporation is proposing to prepare a site for and construct a uranium mine and mill at its Patterson Lake South property located in the southwestern Athabasca Basin in northern Saskatchewan, approximately 155 km north of La Loche, Saskatchewan.
The proposed Patterson Lake South Project includes underground and surface facilities to support the mining and processing of uranium ore. The main components include an underground mine, an onsite mill to process an average of 1,000 tonnes of ore per day, surface facilities to support the short- and long-term storage of waste rock and ore, an underground tailings management facility, water-handling infrastructure and an effluent treatment circuit, and additional infrastructure to support mining activities.
To proceed, the proposed project requires authorization from the CNSC in the form of a licence issued under subsection 24(2) of the Nuclear Safety and Control Act (NSCA).
Before the Commission can make an NSCA licensing decision on this proposal, an environmental assessment (EA) under the province of Saskatchewan’s Environmental Assessment Act must be completed. At the request of the Province of Saskatchewan, the CNSC is acting as a federal expert for nuclear matters in relation to assessing the project.
