Cameco Reports Illegal Work Stoppage at Kumtor Gold Mine

Saskatoon, Saskatchewan, Canada, December 19, 2006   .   .   .   .   .   .   .   .   .   .   .   .    ..

Cameco Corporation reported today that that the mine department and some support services personnel have begun an illegal work stoppage at the Kumtor minesite. Milling operations are continuing utilizing ore stockpiles. This illegal action comes while negotiations are underway on the renewal of the current labour contract, which expires on December 31, 2006. The Kyrgyz minister of labour had previously issued a letter to the Kumtor workforce indicating that under Kyrgyz legislation any work stoppage would be illegal. Meetings are scheduled between the work force, trade union, Kumtor management and the government to resolve the matter.

It has been reported that the government of the Kyrgyz Republic has resigned and it was accepted by the president. The resolution of the illegal strike may be complicated by this situation.

Further updates will be provided as information becomes available.

Cameco owns 53% of Centerra Gold Inc. which owns and operates the Kumtor mine located in the Kyrgyz Republic, Central Asia.

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.
