Cameco Ends Toll-Conversion Agreement with Springfields Fuels Ltd.

SASKATOON, SASKATCHEWAN, CANADA--(Mar. 31, 2014) -

CURRENCY: CDN (UNLESS NOTED)

Cameco (TSX: CCO; NYSE: CCJ) announced today that it will end its toll-conversion agreement with Springfields Fuels Ltd. (SFL) effective December 31, 2014.

In 2005, Cameco signed a 10-year toll-conversion agreement to process up to 5 million kilograms of uranium annually at the Springfields conversion facility in Lancashire, United Kingdom. The Springfields facility receives uranium trioxide (UO₃) from Cameco’s Blind River uranium refinery and converts it to uranium hexafluoride (UF₆), which is required to produce fuel for light water reactors. Cameco delivers the UF₆ to its own customers around the world.

The toll-conversion agreement was set to expire in 2016. Cameco has agreed to pay $18 million to SFL to permit early termination of the agreement. Production for Cameco at the Springfields facility will cease by August 31, 2014. Cameco expects to receive a maximum of 3,731 tonnes of uranium as UF₆ from Springfields in 2014.

“With the current weak market for UF₆ conversion we can meet our customer requirements from our Port Hope conversion facility and benefit from better utilization of existing assets,” said Tim Gitzel, Cameco’s president and CEO.
