Cameco Reports Pit Wall Ground Movement at Kumtor Gold Mine

Saskatoon, Saskatchewan, Canada, July 18, 2006 . . . . . . . . . . . . . .

Cameco Corporation reported today that a pit wall ground movement has occurred at the Kumtor minesite in the Kyrgyz Republic, Central Asia. Cameco owns 53% of Centerra Gold Inc. which owns and operates the Kumtor mine located in the Kyrgyz Republic, Central Asia.

Preliminary engineering analysis since the event indicates that 2006 production at Kumtor is now anticipated to be about 300,000 ounces. Centerra’s most recent prior outlook projected 410,000 - 420,000 ounces of poured gold in 2006. Work is continuing to further quantify the impact of the wall movement on 2007 production.

The incident occurred Thursday, July 13 and involved a significant portion of the northeast wall. Kumtor’s extensive slope monitoring system was effective, enabling advance evacuation of the mining area and there were no injuries although a diamond drill was covered by rock. The movement occurred above the higher-grade stock work area which was planned to be mined beginning late this year and continuing into 2007. While the stock work area was not covered by the rock, due to safety concerns a new mining sequence is necessary which will defer production from this planned area.

Normal operations continue in the south end of the pit as does the milling of low-grade stock piles.

Opportunities to accelerate equipment deliveries are also being pursued. Gold reserves are not expected to be affected as a result of the rock slide as the wall movement lies entirely within the ultimate pit design.

Centerra is a growth-oriented, gold company focused on acquiring, exploring, developing and operating gold properties primarily in Central Asia, the former Soviet Union and other emerging markets. Centerra is a leading North American gold producer and the largest Western-based gold producer in Central Asia and the former Soviet Union. Centerra’s shares trade on the Toronto Stock Exchange (TSX) under the symbol CG. The Company is based in Toronto, Canada.

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.
