Cameco Provides Update on Gold Operation in Kyrgyz Republic

Saskatoon, Saskatchewan, Canada, July 19, 2005 . . . . . . . . . . . . . . .

Cameco Corporation provided an update today on its subsidiary’s gold interests in the Kyrgyz Republic. Cameco holds 53% of Centerra Gold Inc, which in turn owns 100% of the Kumtor mine located in the Kyrgyz Republic. This update follows a visit by Centerra’s senior management to the Krygyz Republic and is issued in tandem with a Centerra news release.

The complex political situation in the Kyrgyz Republic continues to evolve. As expected, the acting President, Mr. Kurmanbek Bakiev, won a landslide victory at the presidential elections held on July 10, 2005. As the new government becomes established, Centerra expects there will be less political uncertainty related to the Kumtor mine. Nevertheless, as the largest foreign investment enterprise in the Kyrgyz Republic, the mine has been and continues to be a focus of political debate. There can be no assurance that the mine will not be affected by the political situation in the country.

In Cameco’s first quarter management’s discussion and analysis, we reported on requests for information from the State Auditing Chamber in connection with its inquiries into the Kumtor restructuring. Since then, the interim government, formed after the departure from office of President Askar Akayev in March 2005, made further information requests. The attorney general’s office requested documents from Kumtor Operating Company (Centerra subsidiary) and Centerra as part of a criminal investigation into alleged abuses of power or authority by officers of the Kyrgyz government, Kyrgyzaltyn JSC (the state-owned entity that formerly held two-thirds of the project and now owns 15.7% of Centerra), Kumtor Gold Company and Kumtor Operating Company. The investigation is based on previous parliamentary resolutions opposing and challenging the Kumtor agreements and the legality of the restructuring. Centerra is being responsive to these requests.

Centerra is not aware of any basis for any allegation of criminal conduct. The Kumtor restructuring involved several multilateral financial institutions and was approved by government decrees and supported by legal opinions of the Ministry of Justice on the authority of the government to enter into and complete the restructuring. Centerra and Cameco have complete confidence in the validity of the restructuring agreements with the government. Disputes about such agreements are subject to resolution by international arbitration. Furthermore, Mr. Bakiev, prior to the presidential elections, stated on several occasions that the Kyrgyz Republic will honour its agreements with foreign investors.

The interim government established a commission in April to inquire into the former president’s assets. The commission has published a report on its findings that does not contain any allegations against Centerra or its Kyrgyz subsidiaries, or Cameco.

We will provide a further update in our second quarter management’s discussion and analysis on developments in the Kyrgyz Republic that may affect Centerra’s operations and on the scheduled tax inspections mentioned in our first quarter management’s discussion and analysis. A tax assessment is expected in the near future.

The Kumtor gold mine continues to function normally.
