Cameco and Kyrgyz Government Reach Agreement

Saskatoon, Saskatchewan, Canada, August 30, 2007 . . . . . . . . . . . . . . .

Cameco Corporation announced today the company and Centerra Gold Inc. have each signed binding agreements with the Kyrgyz government. These agreements are expected to provide additional business certainty for mining operations at Kumtor, further align the parties’ business interests and support Centerra’s growth plans.

Cameco owns 53% of Centerra while Kyrgyzaltyn owns 16%. Cameco and Kyrgyzaltyn JSC, a joint stock company owned by the Kyrgyz government, were partners in the gold company that developed and began production at the Kumtor gold mine, which subsequently became part of Centerra.

Under the terms of the agreements, the Kyrgyz government and Kyrgyzaltyn agree to support Centerra’s continuing long-term development of the Kumtor project and agree to facilitate eventual divestiture of Cameco’s interest in Centerra. In return, the Kyrgyz government will receive 32.3 million shares (22.3 million net from Cameco and 10 million treasury shares from Centerra) upon closing of the definitive legal agreements resulting from the agreements signed today. Of these, 15 million shares will be received immediately and 17.3 million shares will be held in escrow until the earliest of:

• Cameco’s holdings of Centerra’s issued and outstanding shares fall below 17.3 million shares,

• the volume weighted average closing price of Centerra’s shares on the TSX being no less than $13.30 for at least 7 business days, or

• the fourth anniversary of the closing.

After the transfer of all the shares is completed, Cameco will own about 41% of Centerra, the Kyrgyz Republic will own about 29% and the public shareholders will own the remaining 30%. When Cameco’s ownership falls below 50%, we will no longer consolidate Centerra’s financial results and will instead account for Centerra using the equity method. Also as a consequence of the share transfer, Cameco will record a one-time, after-tax loss of about $120 million at closing.

“These agreements provide a platform for a predictable and stable business climate for the Kumtor gold mine,” said Jerry Grandey, Cameco’s president and CEO. “We will work closely with Centerra and the Kyrgyz government to enable Centerra to successfully pursue its mandate.”

Centerra’s agreement provides for the Kyrgyz government’s full support of Centerra’s operations and significantly enlarges its existing mine concession area by over 25,000 hectares to include all territory covered by the current exploration licence. In addition, Centerra’s agreement provides for replacement of the current tax regime with a simplified, new tax rate for the Kumtor operation applied to gross revenue. The new tax rate for the Kumtor project will be 11% in 2008, 12% in 2009 and 13% thereafter.

The signed binding agreements provide the framework for definitive agreements to be entered into upon the receipt of approval by the Parliament of Kyrgyz Republic that resumes sitting on September 3. The Kyrgyz government intends to present the documents for Parliamentary approval in September. While parliamentary approval is not assured, the Kyrgyz government intends to present the documents and make a concerted effort to obtain parliamentary approval.

Cameco expects the two agreements to be finalized in about two months subject to the appropriate approvals by Cameco’s board of directors, Centerra’s board of directors and the Kyrgyz government.

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.
