<P align="center" style="font-size: 12pt"><B>Cameco Confirms Uranium Guidance for 2005</B>


<P align="left" style="font-size: 10pt">Saskatoon, Saskatchewan, Canada, May&nbsp;2, 2005. . . . . . . . . . . . . . .


<P align="left" style="font-size: 10pt">During Cameco&#146;s first quarter conference call held earlier today, a discussion about realized, spot
and long-term uranium prices in US dollars may have caused some confusion regarding guidance for
the uranium business. To clarify, Cameco confirms that its average realized uranium price in 2005
is projected to increase in Canadian dollars by 8% over the 2004 average realized uranium price as
reported in its first quarter report.


<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 maintain and further improve positive labour relations; operating
performance of the facilities; success of planned development projects; and other development and
operating risks.


<P align="left" style="font-size: 10pt">Although Cameco believes that the assumptions inherent in the forward-looking statements are
reasonable, undue reliance should not be placed on these statements, which only apply as of the
date of this report. Cameco disclaims any intention or obligation to update or revise any
forward-looking statement, whether as a result of new information, future events or otherwise.
