</DIV>

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Cameco Corporation </B>reports that remediation work at the No.1 Shaft at its Cigar Lake uranium
project was temporarily suspended today after an increase in the rate of water inflow to the mine
was observed.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&#147;Remediation and dewatering of the No.&nbsp;1 Shaft had been progressing smoothly up to this point,&#148;
said Tim Gitzel, Cameco&#146;s chief operating officer. &#147;An inflow at this rate is disappointing but our
remediation plan, as approved by our joint venture partners, recognized the risk and included
specific actions to be taken at various levels of inflow.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">No.&nbsp;1 Shaft had been pumped down to 430 metres below surface when the increase was reported early
Tuesday morning. Work in the shaft was suspended a few hours later. During the day, the inflow rate
increased steadily to approximately 600 cubic metres per hour (m<SUP style="font-size: 85%; vertical-align: text-top">3</SUP>/hr), which is beyond
the range that can be managed while sustaining work in the shaft. The mine has a total depth of 500
metres and the mine underground workings are at the 480-metre level.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Work in the shaft has been suspended while the situation is assessed to determine the source and
characteristics of the inflow, implications for planned remediation work and the impact, if any, on
our planned production date.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our current plan is to allow the water level in the shaft to rise to approximately 100 metres below
surface. This will allow additional data to be gathered from instruments used to monitor
groundwater conditions. As the water level rises, the rate of inflow will naturally diminish. This
information will be analyzed to determine next steps. After this is complete, the water will be
allowed to return to the natural equilibrium level.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As previously disclosed, the remediation plan for Cigar Lake includes options to address excess
inflows including additional grouting from surface and ground freezing if necessary.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Pumping capacity is 1,000 m<SUP style="font-size: 85%; vertical-align: text-top">3</SUP>/hr from four dedicated dewatering pumps installed in wells
down to the 500-metre level. The water management system is limited by the treated water release
limit of 550 m<SUP style="font-size: 85%; vertical-align: text-top">3</SUP>/hr under the existing licence. There is a 74,000 cubic metre
contingency storage pond at the surface that allows pumping at rates above the release limit for a
limited period.
