Item 3 — News Release

The English version and the French translation version of the press release relating to this material change was distributed and filed by Canadian Corporate News through their Canadian Timely Disclosure Pack and U.S. Timely Disclosure Pack on July 18, 2006.

Item 4 — Summary of Material Change

On July 18, 2006 Cameco announced that a pit wall ground movement had occurred at the Kumtor minesite in Kyrgyz Republic, Central Asia. The incident occurred on Thursday, July 13, 2006 and involved a significant portion of the northeast wall. The movement occurred above the higher-grade stock work area which was planned to be mined beginning late this year and continuing into 2007. 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. Cameco owns 53% of Centerra Gold Inc. which owns and operates the Kumtor mine located in the Kyrgyz Republic, Central Asia.

PAGEBREAK

The incident occurred on Thursday, July 13, 2006 and involved a significant portion of the northeast wall. The movement occurred above the higher-grade stock work area which was planned to be mined beginning late this year and continuing into 2007. 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. 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.
