Cameco Acquires Canadian Nuclear Fuel Manufacturer

Saskatoon, Saskatchewan, Canada, February 1, 2006 . . . . . . . . . . . . . .

Cameco Corporation announced today it has completed the acquisition of a 100% interest in Zircatec Precision Industries, Inc. for $108 million. Zircatec’s primary business is manufacturing nuclear fuel bundles for sale to companies that generate electricity from Candu reactors.

Cameco used cash to fund this acquisition that is expected to be moderately accretive to cash flow and earnings in 2006, assuming there is no significant change to existing revenue and costs.

“With this acquisition, Cameco increases its participation in the nuclear fuel cycle and now covers all phases of the Canadian industry from uranium mining through to electricity generation,” said Jerry Grandey, Cameco’s president and CEO. “Ownership of Zircatec provides Cameco with additional growth opportunities and a new base of assets, managed by knowledgeable employees, to pursue our vision to be a dominant nuclear energy company.”

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.

trade laws and policies; demand for nuclear power; replacement of production; failure to obtain or maintain necessary permits and approvals from government authorities; legislative and regulatory initiatives regarding deregulation, regulation or restructuring of the electric utility industry in Ontario; Ontario electricity rate regulations; weather and other natural phenomena; ability to maintain and further improve positive labour relations; operating performance, disruption in the operation of, and life of the company’s and customer’s facilities; decrease in electrical production due to planned outages extending beyond their scheduled periods or unplanned outages; success of planned development projects; terrorism; sabotage; and other development and operating risks.
