Cameco Receives Request to Discuss Russian Agreement

Saskatoon, Saskatchewan, Canada, October 31, 2007. . . . . . . . . . . . . .

Cameco Corporation reports that the Joint Stock Company Techsnabexport (Tenex) has requested discussions regarding the pricing structure for the last few years of the remaining term of the commercial agreement to purchase uranium derived from dismantled Russian nuclear weapons. Tenex made its request after Cameco announced its third quarter results on October 31, 2007. Cameco and its two partners in the commercial agreement have a long-standing history of working with Tenex on this agreement and other matters. Cameco will confer with its partners before deciding on a course of action going forward.

Cameco currently purchases about 7 million pounds of uranium annually under this commercial agreement, which ends in 2013. The purchase price that Cameco pays for these pounds was agreed to in 2001, when uranium prices were much lower than they are today. As such, Tenex has asked the parties to consider a new pricing structure to share in the improved uranium market prices.

Cameco and its two partners entered into the commercial agreement with Tenex to purchase uranium derived from dismantled Russian weapons in 1999. The commercial agreement was subsequently amended in 2001 and 2004. This commercial agreement falls under the umbrella of the United States-Russia government-to-government agreement to convert highly enriched uranium from dismantled Russian nuclear weapons into fuel for nuclear power plants (the HEU agreement).

The agreements, including the commercial agreement, that implement the HEU agreement presently supply a significant portion of the US enrichment, uranium and conversion services requirements. As a result of these agreements, a quantity of highly enriched uranium equivalent to more than 12,000 nuclear warheads has been recycled to fuel electricity generation. Tenex, Cameco and its western partners (AREVA and Nukem) have all expressed their intent to continue with the commercial agreement.

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.
