<DIV align="center" style="font-size: 12pt; margin-top: 24pt"><B>Cameco Strengthens Uranium Exploration Portfolio</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt">Saskatoon, Saskatchewan, Canada, August&nbsp;29, 2007. . . . . . . . . . . . . .
</DIV>



<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Cameco Corporation </B>announced today that its wholly owned subsidiary, Cameco Global Exploration II
Ltd., has concluded a strategic alliance with Western Uranium Corporation (WUC), which allows
Cameco&#146;s subsidiary to acquire a 70% joint venture interest in WUC&#146;s current properties. As part of
the transaction, Cameco&#146;s subsidiary also became a 10% shareholder of WUC.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">WUC is a uranium exploration and development company with its head office in Vancouver, B.C. Its
principal properties are in Nevada and New Mexico in the US, and Nunavut and the Northwest
Territories in Canada. Shares of WUC trade on the TSX Venture Exchange.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco&#146;s subsidiary purchased 5,586,244 units of WUC at $3.80 per unit. Each unit is comprised of
one common share and one half of a share-purchase warrant. Each whole share-purchase warrant
entitles Cameco&#146;s subsidiary, for one year, to acquire an additional common share for $4.25.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">This transaction provides Cameco&#146;s subsidiary with the following rights: (i)&nbsp;to acquire a 70% joint
venture interest at such time as any of WUC&#146;s current uranium properties warrant development to
production; (ii)&nbsp;to participate in any future equity issues; and (iii)&nbsp;to nominate one person for
election to WUC&#146;s board of directors, as long as the company holds 7.5% of WUC&#146;s outstanding common
shares.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&#147;This transaction strengthens Cameco&#146;s extensive portfolio of exploration investments and gives us
another option to expand future production consistent with our strategy to build on Cameco&#146;s
competitive advantage in the uranium business, &#148; said Cameco president and CEO Jerry Grandey.
&#147;Through our investment and strategic alliance with WUC, Cameco&#146;s shareholders gain the potential
of a quality company with an attractive land position.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">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.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt">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: the impact
of the sales volume of fuel fabrication services, uranium, conversion services, electricity
generated and gold; volatility and sensitivity to market prices for uranium, conversion services,
electricity in Ontario and gold; competition; the impact of change in foreign currency exchange
rates and interest rates; imprecision in decommissioning, reclamation, reserve and tax estimates;
environmental and safety risks including increased regulatory burdens and long-term waste disposal;
unexpected geological or hydrological conditions; adverse mining conditions; political risks
arising from operating in certain developing countries; terrorism; sabotage; a possible
deterioration in political support for nuclear energy; changes in government regulations and
policies, including tax and trade laws and policies; demand for nuclear power; replacement of
production; failure to obtain or maintain 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;
natural phenomena including inclement weather conditions, fire, flood, underground floods,
earthquakes, pit wall failure and cave-ins; ability to maintain and further improve positive labour
relations; strikes or lockouts; operating performance, disruption in the operation of, and life of
the company&#146;s and customers&#146; facilities; decrease in electrical production due to planned outages
extending beyond their scheduled periods or unplanned outages; success of planned development
projects; and other development and operating risks.
