Cameco Negotiating to Acquire Canadian Nuclear Fuel Fabricator.

SASKATOON, Saskatchewan -- Cameco Corporation (TSX:CCO) (NYSE:CCJ) advised today that it is in negotiations to acquire Zircatec Precision Industries, Inc.

Zircatec's primary business is manufacturing nuclear fuel bundles for sale to companies that generate electricity with Candu reactors. Zircatec has one plant in Cobourg, Ontario that produces metal components for fuel bundles and other reactor components. A second plant in Port Hope, Ontario handles nuclear materials and completes the fuel bundle fabrication process.

Cameco's review of Zircatec will determine if it meets the company's investment criteria. Cameco will provide an update on the status of this project once negotiations have proceeded to a point where the company has made an investment decision which is expected by year end.

Cameco, with its head office in Saskatoon, Saskatchewan, is the world's largest uranium producer. The company's uranium products are used to generate electricity in nuclear energy plants around the world, providing one of the cleanest sources of energy available today. Cameco's shares trade on the Toronto and New York stock exchanges.
