Saskatoon, Saskatchewan, Canada, August 10, 2009

Cameco Corporation (TSX: CCO; NYSE: CCJ) announced today that there are no undisclosed material developments related to the progress of divesting the company’s interest in Centerra Gold Inc.

Cameco has consistently stated its intent to divest its shares in Centerra when the opportunity arose. Contrary to speculation, the company is not working with underwriters to draft a preliminary prospectus.

Cameco, with its head office in Saskatoon, Saskatchewan, is one of the world’s largest uranium producers.
