Rabbit Lake

  • Opening in 1975, Rabbit Lake was the longest operating uranium mine in North America.
  • Over 41 years of mining, the operation produced more than 203 million pounds of uranium concentrates.

  • Rabbit Lake was transitioned into safe care and maintenance in the second quarter of 2016.

2017 Update

Production Suspension

The facilities remained in a state of safe and sustainable care and maintenance throughout 2017. As a result, there was in no production in 2017.

We are continually weighing the value of maintaining the operation in standby, against the cost of doing so. However, as long as production is suspended, we expect care and maintenance costs to range between $35 million and $40 million annually for the first few years. The estimated decommissioning cost for the Rabbit Lake mine site is $203 million, based on the preliminary decommissioning cost estimate that has been accepted by the Province of Saskatchewan and the CNSC.
