Rabbit Lake Tailings Expansion

An expanded tailings facility would give the Rabbit Lake Operation the flexibility to adapt to emerging opportunities in the region while minimizing our environmental footprint.

Cameco is currently examining tailings options for Rabbit Lake for both the short- and longer-term.

Cameco has submitted to regulators a plan to better utilize the available tailings capacity at Rabbit Lake's existing In-pit Tailings Management Facility (RLITMF) which has safely stored the operation's tailings since 1986. This plan will require regulatory approval in 2016 and the process to obtain that approval has begun.

Cameco expects this initiative would provide sufficient tailings capacity to support milling of Eagle Point ore until about 2021.

Cameco will also be seeking regulatory approval to expand the tailings capacity at the Rabbit Lake site for the longer-term. This proposal would see expansion of the existing RLITMF through the construction, operation and ultimate decommissioning of the Rabbit Lake Tailings North Pit Expansion (See Project Description) An environmental assessment is underway which builds upon this work and includes environmental modelling of the potential impacts of the project on the environment.

Cameco's vision for the future of the Rabbit Lake Operation is continued safe, clean and reliable production. An expanded tailings facility would give the Rabbit Lake Operation the flexibility to adapt to emerging mining and milling opportunities in the region while still limiting the operation’s environmental footprint.
