<P align="center" style="font-size: 10pt"><B>Cameco Confirms One Bruce Reactor Taken Off-line</B>


<P align="left" style="font-size: 10pt">Saskatoon, Saskatchewan, Canada, April&nbsp;17, 2005


<P align="left" style="font-size: 10pt"><B>Cameco Corporation </B>confirmed today that unit 6 at the Bruce B generating station was safely shut
down at 7:45 p.m. on April&nbsp;15 following a brief transformer fire outside the nuclear generating
station.


<P align="left" style="font-size: 10pt">No one was injured by the incident and Bruce Power is investigating the cause of the fire which was
quickly extinguished by an automatic sprinkler system. The incident caused the release of mineral
oil which is used as an insulator in the transformer. Efforts continue to recover the mineral oil
which is biodegradable and contains no PCBs or radioactive material.


<P align="left" style="font-size: 10pt">Bruce Power is determining how long it will take to repair the transformer and return unit 6 to
service.


<P align="left" style="font-size: 10pt">Units 3, 5, 7 and 8 at the generating station remain at high power while Bruce Power continues the
planned inspection of unit 4 that began on March&nbsp;12. Cameco indirectly holds a 31.6% interest in
Bruce Power Limited Partnership, which leases the Bruce nuclear plants in Ontario.


<P align="left" style="font-size: 10pt">Cameco, with its head office in Saskatoon, Saskatchewan, is the world&#146;s largest uranium producer.
The company&#146;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&#146;s shares trade on
the Toronto and New York stock exchanges.


<P align="left" style="font-size: 10pt">Statements contained in this news release which are not historical facts are forward-looking
statements that involve risks, uncertainties and other factors that could cause actual results to
differ materially from those expressed or implied by such forward-looking statements. Factors that
could cause such differences, without limiting the generality of the following, include: volatility
and sensitivity to market prices for uranium, electricity in Ontario and gold; the impact of the
sales volume of uranium, conversion services, electricity generated and gold; competition; the
impact of change in foreign currency exchange rates and interest rates; imprecision in reserve
estimates; environmental and safety risks including increased regulatory burdens; unexpected
geological or hydrological conditions; political risks arising from operating in certain developing
countries; a possible deterioration in political support for nuclear energy; changes in government
regulations and policies, including trade laws and policies; demand for nuclear power; replacement
of production and failure to obtain necessary permits and approvals from government authorities;
legislative and regulatory initiatives regarding deregulation, regulation or restructuring of the
electric utility industry

reasonable, undue reliance should not be placed on these statements, which only apply as of the
