<P align="center" style="font-size: 10pt"><B>Cameco Makes Progress on Adding Nuclear Capacity at Bruce Power</B>



<P align="left" style="font-size: 10pt">Saskatoon, Saskatchewan, Canada, March&nbsp;21, 2005 . . . . . . . . . . . . . .

<P align="left" style="font-size: 10pt"><B>Cameco Corporation </B>confirmed today that, together with its partners TransCanada and BPC Generation
Infrastructure Trust, it is making progress towards restarting the two shutdown reactors at the
Bruce Power site in Ontario.


<P align="left" style="font-size: 10pt">As part of this process, Bruce Power and the negotiator appointed by the Ontario government
announced today they have reached a tentative agreement on restarting the two reactors. Cameco has
approved in principle this tentative agreement which requires final government approval. The
process of reaching a mutually acceptable binding agreement continues, but has not been completed.


<P align="left" style="font-size: 10pt">Cameco will provide an update on the status of the project once the company has entered a mutually
acceptable, binding agreement with all parties. 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 in Ontario; Ontario electricity rate regulations; weather and other
natural phenomena; ability to

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