long-term commitments for a significant volume of contracts for conversion services with
utility customers to baseload this new agreement.</TD>

<P align="left" style="font-size: 10pt">Saskatoon, Saskatchewan,
Canada, March&nbsp;16, 2005  . . . . . . . . . . . . . . . . . .  . .
.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
.. . . . . . . .


<P align="left" style="font-size: 10pt"><B>Cameco Corporation </B>announced today that it has signed a toll-conversion agreement with British
Nuclear Fuels plc (BNFL)&nbsp;to acquire uranium conversion services (UF<SUB>6</SUB>) from BNFL&#146;s
Springfields plant in Lancashire, United Kingdom. Under the 10-year agreement, BNFL will annually
convert a base quantity of 5&nbsp;million kilograms of uranium (kgU) as UO<SUB>3</SUB> to UF<SUB>6</SUB>
for Cameco.


<P align="left" style="font-size: 10pt">In 2001, BNFL announced that the Springfields facility would close in 2006. This new agreement will
keep the plant operating for the duration of the agreement.


<P align="left" style="font-size: 10pt">Cameco currently refines uranium concentrates to UO<SUB>3</SUB> at the Blind River refinery and
ships this material to the Port Hope conversion facility. Both facilities are located in Ontario.
Under the agreement with BNFL, Cameco will also ship UO<SUB>3</SUB> from its Blind River refinery
to BNFL&#146;s conversion plant where it will be toll converted to UF<SUB>6</SUB>. Cameco will then
deliver the UF<SUB>6</SUB> to its utility customers who ultimately use it for fuel in nuclear
reactors after further processing. Cameco currently has more than a quarter of the western world&#146;s
UF<SUB>6</SUB> conversion capacity from its Port Hope plant.


<P align="left" style="font-size: 10pt">Cameco will invest about $6&nbsp;million to expand production and drum-filling facilities at its Blind
River refinery and $4&nbsp;million to construct drum tipping and washing facilities at BNFL&#146;s
Springfields plant. UO<SUB>3</SUB> shipments from Blind River are expected to begin later this year
with UF<SUB>6</SUB> conversion shipments from BNFL starting in mid-2006. Cameco expects this
agreement will be accretive to operating cash flow and earnings beginning in 2006.


<P align="left" style="font-size: 10pt">&#147;This agreement allows us to effectively achieve a significant increase in UF<SUB>6</SUB>
production capacity, sales and market share by investing a small amount of capital,&#148; said Jerry
Grandey, Cameco&#146;s president and CEO. &#147;At the same time, it preserves Springfields&#146; production
capacity at a critical time in the industry and enables us to lower our unit costs by utilizing
Blind River&#146;s unused capacity.&#148;


<P align="left" style="font-size: 10pt">Historically, the Blind River refinery has not operated anywhere near full capacity since it has
been limited by the capacity of Cameco&#146;s conversion facility at Port Hope which receives
essentially all of Blind River&#146;s UO<SUB>3 </SUB>production.


<P align="left" style="font-size: 10pt">Cameco has already secured long-term commitments for a significant volume of contracts for
conversion services with utility customers to baseload this new agreement.


<P align="left" style="font-size: 10pt">&#147;Today Cameco has taken another step toward its vision to be a dominant nuclear energy company
producing uranium fuel and generating clean electricity,&#148; Grandey said.

<P align="left" style="font-size: 10pt">BNFL is an international nuclear energy company based in the United Kingdom. In April&nbsp;2005,
ownership of the Springfields plant is scheduled to be transferred to Britain&#146;s Nuclear
Decommissioning Authority (NDA), a government agency established to take responsibility for the
majority of the United Kingdom&#146;s civil nuclear assets and liabilities.


<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.
