(a) After working capital changes.
(b) 2004 net earnings for the three months ended September 30 have
been adjusted to exclude a net gain of $5 million ($0.03 per share)
related to the Centerra restructuring transactions. This is a
non-GAAP measure and Cameco believes the exclusion of this item
provides a more meaningful basis for period-to-period comparisons
of the company's financial results.

In the third quarter of 2005, our net earnings were $78 million ($0.43 per share), $31 million higher than the adjusted net earnings in 2004, due to increased earnings from Bruce Power and improved results in the uranium business. These increases were partially offset by lower profits in our gold business and higher charges for administration, exploration and income taxes. Cash from operations in the third quarter of 2005 was $148 million compared to $140 million in the third quarter of 2004. Due to the uneven timing of uranium and conversion deliveries as well as scheduled outages at Bruce Power, quarterly results are not a good indicator of Cameco's annual results.

The improved results in our uranium business were due to higher uranium prices. Our average realized selling price for uranium increased by 26% in US dollars to $15.46 (US) versus the third quarter of 2004. Cameco's average realized price in Canadian dollars increased by only 18% due to the strengthening Canadian dollar relative to the US dollar. The increase in our average realized price was mainly the result of higher prices under fixed-price contracts and a higher uranium spot price, which averaged $30.41 (US) per pound in the third quarter of 2005, up 58% from the same period last year.

Cameco's pre-tax earnings from Bruce Power in the third quarter of 2005 increased to $97 million from $28 million in 2004, as a result of higher electricity prices in Ontario. Bruce Power realized an average price of $70 per megawatt hour (MWh) in the third quarter from a mix of contract and spot sales, 56% higher than the price realized in the same period in 2004. During the quarter, the Ontario electricity spot price averaged $86 per MWh, compared to $46 per MWh in the third quarter of 2004. The higher electricity spot prices in 2005 were due to an increase in demand as a result of the hot weather, which persisted through the quarter.

"We are pleased with the higher realized uranium prices and the higher earnings from Bruce Power that contributed to a strong quarter," said Jerry Grandey, Cameco's president and CEO. "And we anticipate they will be significant contributors going forward."

(a) After working capital changes.
(b) 2004 net earnings for the nine months ended September 30 have
been adjusted to exclude a net gain of $94 million ($0.55 per share)
related to Centerra restructuring transactions. This is a non-GAAP
measure and Cameco believes the exclusion of this item provides a
more meaningful basis for period-to-period comparisons of the
company's financial results.

For the nine months ended September 30, 2005, our net earnings were $136 million ($0.76 per share), $12 million lower than the adjusted net earnings reported in 2004. The decline is due largely to higher charges for administration and increased spending on exploration. Cameco plans to invest $23 million for uranium exploration as part of its long-term plan to maintain its leadership position in uranium.

In the first nine months of 2005, Cameco generated cash from operations of $186 million, up $17 million compared to 2004. This increase was mainly attributable to higher gold sales compared to the previous year and cash distributions received from Bruce Power ($68 million), partially offset by an increase in uranium and conversion inventory levels.

At September 30, 2005, our consolidated net debt to capitalization ratio was 14%, up slightly from 13% at the end of 2004.

Consolidated Outlook for Fourth Quarter 2005

Effective November 1, 2005, Cameco will proportionately consolidate Bruce Power's financial results. In the past, we have accounted for Bruce Power using the equity method. The move to this new method of accounting is driven by changes to the partnership agreement, which provide for joint control among the three major partners. We expect that the proportionate consolidation of Bruce Power will add about $60 million to our reported revenues for the fourth quarter. Including these revenues from Bruce Power, we expect consolidated revenue in the fourth quarter of 2005 to be about 89% higher than in the third quarter of 2005 due to higher uranium and conversion deliveries. Earnings from Bruce Power are expected to be significantly lower than in the third quarter of 2005 due to expected lower realized prices and to no longer sharing in the operating results of the Bruce A units. Consolidated earnings for the fourth quarter of 2005 are expected to be moderately higher than those of the third quarter as the reduced earnings from Bruce Power largely offset the improved results in the uranium business.

The outlook for the fourth quarter excludes the approximate $63 million loss that was triggered by the completion of the Bruce A restructuring and the expected gain from Cameco's sale of its share in Energy Resources of Australia Ltd (ERA). For more information on the Bruce A restructuring see the section titled Nuclear Electricity Generation in the MD&A that follows this news release.

Outlook for the Year

In 2005, consolidated revenue is expected to grow by more than 20% over 2004 due to increases in our uranium and gold businesses as well as proportionate consolidation of the Bruce Power revenues. On a consolidated basis, our gross profit margin is projected to improve from the 23% reported in 2004.

In our uranium business, revenue is expected to be about 15% higher due to a projected 11% improvement in the Canadian dollar selling price and a 5% increase in deliveries. Revenue from our conversion business is expected to be marginally higher than in 2004 due to an anticipated 10% increase in the average realized selling price, largely offset by lower deliveries. Bruce Power earnings in 2005 are projected to be significantly higher than in 2004 mainly as a result of higher realized prices during the summer months. This outlook reflects the completion of the Bruce A restructuring, but excludes the loss it triggers and also excludes the gain expected from Cameco's sale of its shares in ERA. Revenue in our gold business is expected to be higher due primarily to a full year of consolidating the results from Kumtor and increased production at Boroo. In 2005, our gold results are projected to decline compared to 2004 due to higher unit costs and increased spending in exploration, which will offset the expected increase in revenue.

For 2005, the effective tax rate is expected to be approximately 20%.

CONSOLIDATED FINANCIAL RESULTS

Consolidated Earnings

In 2004, Cameco recorded an after tax gain of $94 million ($0.55 per share) related to certain restructuring transactions that led to the creation of Centerra Gold Inc. (Centerra). The following discussion of consolidated earnings excludes this net gain to provide a more meaningful comparison of operating results. All references to per share earnings or losses are based on diluted earnings or losses per share.

Third Quarter

For the three months ended September 30, 2005, our net earnings were $78 million ($0.43 per share), $31 million higher than the adjusted net earnings of $47 million ($0.26 per share) recorded in 2004 due to higher earnings from Bruce Power LP (Bruce Power) and improved results in the uranium business. These increases were partially offset by lower profits in the gold business and higher charges for administration and income taxes as well as increased spending on exploration.

For details on the uranium, conversion services, electricity and gold businesses, see "Business Segment Results" later in this report.

In the third quarter of 2005, total costs for administration, exploration, interest and other were about $46 million, $10 million higher than 2004. Administration costs increased by $6 million due to higher stock compensation charges from increased share prices ($3 million), higher administration costs at Centerra ($1 million) and higher expenditures for regulatory compliance. In the third quarter, Cameco and its subsidiaries incurred costs of $1 million related to Sarbanes-Oxley compliance.

Exploration expenditures rose by $5 million to $16 million due to increased exploration activity in both the gold and uranium businesses. In uranium exploration, a $2 million increase in expenditures was related to programs around existing mines in the Athabasca Basin in northern Saskatchewan. In the gold business, Cameco's 53% owned subsidiary, Centerra, increased its exploration expenditures by $3 million compared to 2004. The higher charges reflect increased gold exploration activity in the Kyrgyz Republic and Mongolia.

Our effective tax rate increased to 24% in the third quarter from 12% in the same period of 2004 due to a greater proportion of total income being earned in Canada. The income tax expense in the third quarter was heavily influenced by earnings from Bruce Power, which represented 90% of pre-tax income. Earnings from Bruce Power are taxed at a rate of 33%.

Earnings from operations were $14 million in the third quarter of 2005 compared to $32 million in 2004. The aggregate gross profit margin decreased to 21% from 22% in 2004.

Year to Date

For the nine months ended September 30, 2005, our net earnings were $136 million ($0.76 per share), $12 million lower than the adjusted net earnings of $148 million ($0.83 per share) reported in 2004 due largely to higher charges for administration and exploration. These cost increases were partially offset by improved results in our uranium business and improved earnings from Bruce Power.

For details on the uranium, conversion services, electricity and gold businesses, see "Business Segment Results" later in this report.

In 2005, total costs for administration, exploration, interest and other were about $122 million, $42 million higher than 2004. Administration costs increased by $27 million due to higher stock compensation charges from increased share prices ($10 million), higher administration and business development costs at Centerra ($8 million), higher expenditures for regulatory compliance ($5 million directly related to Sarbanes-Oxley compliance) and higher community donations ($1 million).

Exploration expenditures rose by $18 million to $40 million due to increased exploration activity in both the gold and uranium businesses. Our uranium exploration expenditures increased by $5 million to $17 million and were related to programs around existing mines in the Athabasca Basin in northern Saskatchewan. We plan to invest $23 million in uranium exploration in 2005 as part of our plan to maintain our long-term leadership position. In the gold business, Centerra has increased its exploration expenditures by $13 million to $23 million compared to 2004. The higher charges reflect increased exploration activity in the Kyrgyz Republic and Mongolia.

In the first nine months of 2005, our effective tax rate increased to 22% from 21% in the same period of 2004 due to a lower proportion of income being earned in jurisdictions with favourable tax rates relative to Canada.

Earnings from operations were $66 million in the first nine months of 2005 compared to $80 million in 2004. The aggregate gross profit margin was unchanged at 23%.

---------------------------------------------------------------------

Deliveries in our uranium and conversion businesses tend to be higher in the fourth quarter. Net earnings do not trend directly with revenue because they are significantly influenced by results from Bruce Power. The equity method of accounting is applied to the investment in Bruce Power and thus no Bruce Power revenue is recorded. Cash from operations tends to be quite volatile due largely to the timing of deliveries and product purchases in the uranium and conversion businesses.

Cash Flow

In the third quarter of 2005, we generated $148 million from operations compared to $140 million in the same period of 2004. The $8 million increase reflects cash distributions received from Bruce Power, which were offset by higher inventories.

In the first nine months of 2005, Cameco generated cash from operations of $186 million compared to $169 million in 2004. This increase of $17 million was mainly attributable to higher gold sales compared to the previous year and cash distributions received from Bruce Power ($68 million), partially offset by an increase in inventory levels (see the balance sheet section that follows for more details).

Cameco's cash from operations do not include its pro rata interest in Bruce Power's operating cash flow. The pro rata share would have been $161 million in the first nine months of 2005 compared to $141 million in 2004. Cameco accounts for this investment using the equity method of accounting and thus Bruce Power's operating cash flows are not consolidated with Cameco's. For further information, refer to note 2 of the unaudited interim consolidated financial statements and notes for the period ended September 30, 2005.

Balance Sheet

At September 30, 2005, our total debt was $654 million, an increase of $135 million compared to December 31, 2004. At September 30, 2005, our consolidated net debt to capitalization ratio was 14%, up from 13% at the end of 2004.

Compared to the end of 2004, product inventories increased by $141 million as production and purchases of uranium and conversion services exceeded sales during the first nine months of 2005. Substantially all of the increase in inventory was attributable to greater volumes rather than cost. Of this increase, about $94 million was related to higher uranium inventory levels and about $31 million was due to higher conversion inventories. The accumulation of inventory in the first nine months of the year is typical in our uranium and conversion businesses where deliveries are usually concentrated in the latter part of the year. In 2005, 45% of the uranium sales deliveries and 40% of the conversion sales are projected to occur in the fourth quarter.

At September 30, 2005, our consolidated cash balance totalled $295 million and Centerra, Cameco's 53% subsidiary, held more than 80% of this amount.

Cameco has a number of investments in publicly traded entities. The following table illustrates the book and market values for its more significant holdings.

Foreign Exchange Update

Cameco sells most of its uranium and conversion services in US dollars while most of its uranium and conversion services are produced in Canada. As such, these revenues are denominated mostly in US dollars, while production costs are denominated primarily in Canadian dollars.

We attempt to provide some protection against exchange rate fluctuations by planned hedging activity designed to smooth volatility. Therefore, our uranium and conversion revenues are partly sheltered against declines in the US dollar in the shorter term.

In addition, Cameco has a portion of its annual cash outlays denominated in US dollars, including uranium and conversion services purchases, which provide a natural hedge against US currency fluctuations. While natural hedges provide this protection, the influence on earnings from purchased material in inventory is likely to be dispersed over several fiscal periods and is more difficult to identify.

During the quarter, the Canadian dollar strengthened against the US dollar from $1.23 ($0.82 (US) = $1.00 (Cdn)) at June 30, 2005 to $1.16 ($0.86 (US) = $1.00 (Cdn)) at September 30, 2005.

At September 30, 2005, we had a foreign currency hedge portfolio of $1.013 billion (US). The schedule of designations, by year, is as follows:

These hedges are expected to yield an average exchange rate of $1.22. The net mark-to-market gain on these hedge positions was $72 million at September 30, 2005.

Timing differences between the maturity dates and designation dates on previously closed hedge contracts may result in deferred revenue or deferred charges. At September 30, 2005, deferred revenue totalled $20 million. The schedule for deferred revenue to be released to earnings, by year, is as follows:

For the remainder of 2005, approximately 69% of the net inflows of US dollars are hedged with currency derivatives. Net inflows represent forecast uranium and conversion sales less expected outlays (denominated in US dollars). For the uranium and conversion services businesses in the third quarter of 2005, the effective exchange rate, after allowing for hedging, was about $1.31 compared to $1.39 in the third quarter of 2004. Results from the gold business are translated into Canadian dollars at prevailing exchange rates.

For the remainder of 2005, every one-cent change in the US to Canadian dollar exchange rate would change net earnings by about $1 million (Cdn).

Consolidated Outlook for Fourth Quarter 2005

Effective November 1, 2005, Cameco will proportionately consolidate Bruce Power's financial results. In the past, we have accounted for Bruce Power using the equity method. The move to this new method of accounting is driven by changes to the partnership agreement, which provide for joint control among the three major partners. We expect that the proportionate consolidation of Bruce Power will add about $60 million to our reported revenues for the fourth quarter. Including these revenues from Bruce Power, we expect consolidated revenue in the fourth quarter of 2005 to be about 80% higher than in the third quarter of 2005 due to higher uranium and conversion deliveries. Earnings from Bruce Power are expected to be significantly lower than in the third quarter of 2005 due to expected lower realized prices and to no longer sharing in the operating results of the Bruce A units. Consolidated earnings for the fourth quarter of 2005 are expected to be moderately higher than those of the third quarter as the reduced earnings from Bruce Power largely offset the improved results in the uranium business.

The outlook for the fourth quarter excludes the approximate $63 million loss that was triggered by the completion of the Bruce A restructuring and the expected gain from Cameco's sale of its share in Energy Resources of Australia Ltd (ERA). For more information on the Bruce A restructuring see the section titled Nuclear Electricity Generation in this MD&A.

Consolidated Outlook for the Year

In 2005, consolidated revenue is expected to grow by more than 20% over 2004 due to increases in the uranium and gold businesses as well as the proportionate consolidation of Bruce Power revenues. On a consolidated basis, the gross profit margin is projected to improve from the 23% reported in 2004.

In the uranium business, revenue is expected to be about 15% higher due to a stronger realized price and increased volumes. About 45% of the uranium sales deliveries occur in the fourth quarter. Revenue from the conversion business is expected to be marginally higher than in 2004 due to an anticipated 10% increase in the average realized selling price, largely offset by lower deliveries.

Bruce Power earnings in 2005 are projected to be significantly higher than in 2004 mainly as a result of higher realized prices during the summer months. This outlook excludes the loss that was triggered by the completion of the Bruce A restructuring.

We expect revenue in the gold business to be higher due primarily to a full year of consolidating the results from Kumtor and increased production at Boroo. In 2005, gold operating results are projected to decline compared to 2004 due to higher costs and increased spending in exploration, which will offset the expected increase in revenue.

Administration and exploration costs are projected to be about 40% greater than in 2004. The increase in administration reflects higher charges for stock compensation, a full year of Centerra administration costs and regulatory compliance. Exploration costs will increase due to greater activity in both the uranium and gold business.

For 2005, the effective tax rate is expected to be approximately 20%.

Uranium Results

Third Quarter

Compared to the third quarter of 2004, revenue from the uranium business decreased by 6% to $154 million due to a 21% decline in sales volume. As the timing of deliveries of nuclear products within a calendar year is at the discretion of customers, our quarterly delivery patterns can vary significantly. The impact of the reduced volume was partially offset by an increase in the average realized selling price, which rose 26% (in US dollars) over the third quarter of 2004. The average realized price in Canadian dollars increased by only 18% due to the strengthening Canadian dollar relative to the US dollar. The increase in the average realized price was mainly the result of higher prices under fixed-price contracts and a higher uranium spot price, which averaged $30.41 (US) per pound in the third quarter of 2005 compared to $19.29 (US) in the third quarter of 2004.

The total cost of products and services sold, including depreciation, depletion and reclamation (DDR) was $121 million in the third quarter of 2005 compared to $138 million in 2004. This decrease was attributable to the 21% decline in sales volume. The unit cost of product sold rose by 10% compared to the third quarter of 2004 due to higher costs for purchased uranium.

Earnings before taxes from the uranium business improved to $30 million from $21 million last year, while the profit margin rose to 21% from 15% in 2004 due to the higher realized selling price.

Year to Date

Our revenue from the uranium business decreased by 2% to $372 million in 2005 due to a 14% decline in sales volume. This was largely offset by an increase in the average realized selling price, which rose 14% in Canadian dollar terms (20% in US dollars) over the first nine months of 2004. The increase in the average realized price was mainly the result of higher prices under fixed-price contracts and a higher uranium spot price, which averaged $26.63 (US) per pound in the first nine months of 2005 compared to $17.94 (US) in 2004.

Our total cost of products and services sold, including DDR was $293 million in 2005 compared to $319 million in 2004. This decrease was attributable to the 14% decline in sales volume, partially offset by a 6% increase in the unit cost of product sold. The rise in the unit cost of product sold was due primarily to higher costs for purchased uranium.

Earnings before taxes from the uranium business improved to $68 million from $49 million last year, while the profit margin rose to 21% from 16% in 2004 due to the higher realized selling price.

Uranium Outlook for the Year

In 2005, we expect uranium revenue to be about 15% higher than in 2004 due to a projected 11% improvement in the Canadian dollar selling price and a 5% increase in deliveries. Uranium sales volume is expected to total about 34 million pounds in 2005, up marginally from our original target. About 45% of uranium deliveries are expected to occur in the last quarter of the year compared to 2004 when 33% of the sales were delivered in the fourth quarter. In 2005, Cameco's share of uranium production is projected to increase to 21.1 million pounds of U3O8 from 20.5 million in 2004.

Uranium margins are expected to improve to about 24% compared to 18% in 2004.

Uranium Outlook for Fourth Quarter 2005

We expect earnings before taxes from the uranium segment to be nearly double those recorded in the third quarter of 2005 due to higher sales volume. The realized price is expected to be similar to that of the third quarter.

Uranium Price Sensitivity

For deliveries during the remainder of 2005, a $1.00 (US) per pound change in the uranium spot price from $33.00 (US) per pound would change revenue by about $1 million (Cdn). This sensitivity is based on an expected effective exchange rate of $1.00 (US) being equivalent to about $1.24 (Cdn).

Over the past several years, Cameco's strategy has been to ensure adequate cash flow in the near term, while preserving upside potential with a mix of spot price related and fixed-price (escalated by inflation) contracts. Many of our existing contracts have limited sensitivity to rising prices due to the fact that some are based on fixed prices, while others contain ceiling prices that were negotiated when uranium prices were significantly lower. Given the level of sales targeted each year, we are continually in the market signing new contracts for deliveries beginning up to four years in the future. Over the next four years, the current contract portfolio will be replaced in large part with contracts that were entered into in the previous two to three years.

During this period of rapidly increasing spot and long-term prices, Cameco has continued to enter into new multi-year contracts with the evolving contract portfolio reflecting a mix of fixed and market-related prices. For the time being we continue to generally target our traditional blend of pricing mechanisms, which is 40% of sales volume with fixed pricing escalated by inflation and 60% with pricing related to market prices at the time of delivery. Depending on the contract market conditions, we may adjust our 60-40 blend of prices from time to time.

The fixed-price contracts have prices that were set at the time of contract signing. This means we have some contracts at fixed prices below the current spot market prices and they fall into the category of "insensitive" to market price, as noted below. Cameco continues to secure more favourable terms in market price related contracts, including firm floor prices in the mid $20 (US) range (escalated by inflation).

During the past period of low prices, we attempted to keep the term of contracts as short as possible (three to five years). In the current market environment we are committing to longer-term contracts (up to 10 years or more) where the pricing terms provide downside protection (floor prices) and retain upside potential.

The following table shows the approximate percentage of our targeted sales volume that will be impacted by increases in the spot price above $33.00 (US) per pound U3O8. The proportion of targeted sales that is price sensitive increases in 2006 and continues to grow in 2007 and 2008. While the percentage of sales targets that is price insensitive has increased relative to the previous quarter, it is important to note that the value of the portfolio has risen as we secure new contracts due to new higher fixed-price contracts and higher ceiling prices in a rising market.

(1) Fixed-price contracts and market-related contracts not sensitive
    to increases in the spot price above $33.00 (US) per pound.

(2) Market-related contracts plus uncommitted volumes.

The percentages of price insensitive and price sensitive volume would not change significantly for spot price decreases down to the $20 (US) range.

By 2008, Cameco should be realizing most of the benefit of today's improved uranium prices, assuming prices remain at current levels.

Uranium Market Update

Uranium Spot Market

The industry average spot price (TradeTech and UxC) on September 30, 2005 was $31.63 (US) per pound U3O8, up 9% from $29.00 (US) at June 30, 2005. This compares to $20.00 (US) and $18.50 (US) for the same dates in 2004.

Spot market volume reported for the third quarter of 2005 was 2.5 million pounds U3O8 for a total of 22.7 million pounds for the first nine months of the year. This compares to 6.2 million pounds in the third quarter of 2004 and a year to date total at that time of 16.7 million pounds. Spot market volume in the third quarter was considerably lower than in each of the previous two quarters, reflecting the traditional slowdown during the summer months. However, suppliers continued to increase their offer prices, reflecting the limited availability of supplies and the anticipation  of increased demand later in the year.

Discretionary purchases in the spot market continued at a high rate, reflecting utility purchases, likely for inventory building, and both trader and investment groups taking positions in a moving market. It is expected that spot market demand will increase in the fourth quarter while supply remains tight, adding upward pressure to price.

Uranium Long-Term Market

The long-term market continued to be active in the third quarter. Long-term contracting in 2005 is expected to significantly exceed the estimated 90 million pounds U3O8 contracted in 2004.

The industry average long-term price (TradeTech and UxC) on September 30, 2005 was $32.50 (US) per pound U3O8, up from $30.00 (US) at the end of June 2005. This compares to $23.00 (US) and $18.75 (US) for the same dates in 2004.

---------------------------------------------------------------------
---------------------------------------------------------------------

In the first nine months of 2005, our share of uranium production was 16.4 million pounds, an increase of 2.0 million pounds or 14% over 2004.

McArthur River/Key Lake

Cameco's share of production at McArthur River/Key Lake totalled 10.4 million pounds for the first nine months of 2005, which compares favourably to the 9.1 million pounds produced during the same period in 2004.

Our third quarter production equalled 3.9 million pounds versus 3.2 million pounds in the second quarter of 2005. Quarter to quarter variation in production is typical and is a result of timing of plant maintenance shutdowns and normal variation in ore production. Cameco's share of production for the fourth quarter of 2005 is expected to be 2.7 million pounds as the operation is expected to reach the licensed annual production capacity limit of 18.7 million pounds (Cameco's share 13.1 million pounds) of U3O8 near the end of November.

We have applied for an increase in the annual licensed capacity at McArthur River and Key Lake to 22 million pounds U3O8 per year compared to the current 18.7 million pounds. The Canadian Nuclear Safety Commission (CNSC) is considering the appropriate process to complete its review of the impacts associated with this proposed expansion. Once the process is identified, we will be in a better position to estimate the time required for the CNSC to reach a decision. If approval is received, we expect it will take about two years to ramp up production to a sustained level, with a planned production rate of approximately 21 million pounds. This production rate may change as we gain experience in ramping up production.

Continued drilling near the McArthur River mine area has yielded positive results. We are conducting additional confirmatory drilling. We expect to discuss these results in the fourth quarter report.

Rabbit Lake

Rabbit Lake produced 1.4 million pounds of U3O8 during the third quarter of 2005 and a total of 4.5 million pounds of U3O8 for the first nine months of 2005. The additional production achieved relative to 2004 resulted from a significant increase in milled tonnage. We expect production for the fourth quarter of 2005 to be similar to the third quarter. We are on track to achieve a planned production of 5.8 million pounds of U3O8 in 2005.

An extensive diamond-drilling program over the last two years continues to yield good results and we hope to extend the mine life beyond 2007. One new mining zone will be ready for production in early 2006.

Work continues on the environmental assessment (EA) to process a little over half of the uranium from Cigar Lake ore at the Rabbit Lake mill beginning in 2009. Draft guidelines that define the scope of the EA were issued by the regulators in September for public review.

Smith Ranch-Highland and Crow Butte

Smith Ranch-Highland and Crow Butte in situ leach (ISL) mines produced 0.5 million pounds U3O8 in the third quarter of 2005 and 1.5 million in the first nine months of the year. The operations are expected to produce 2.2 million pounds in 2005, marginally below the annual target of 2.3 million.

Uranium Projects Update

Cigar Lake

Construction began on January 1, 2005 and remains on schedule for completion in the first half of 2007. The capital costs for the Cigar Lake project are currently forecast to increase by about 15% to $520 million from $450 million. Our share is 50%. The increase is largely due to greater than anticipated contractor rates driven by the high level of construction activity in western Canada, increased energy costs and several scope additions for project optimization. The scope changes include increasing the capacity of power transmission lines serving the site, the addition of an overhead crane for maintenance of the mill, improvements to the site's sewage treatment plant and fire protection system, and expansion of the construction camp facilities. Also included are enhancements to Cigar Lake's environmental management system requested by the CNSC.

The development of the second shaft is approximately 75% complete and development of the underground workings is approximately 40% complete. Ground freezing of the first area planned for production began in September. Surface construction commenced in June. Once production begins, there will be a ramp-up period of up to three years before the mine reaches expected full production of 18 million pounds per year.

Inkai

The ISL test mine at Inkai, block 2 in Kazakhstan produced about 0.1 million pounds U3O8 during the third quarter of 2005 and 0.4 million for the first nine months of the year. The test mine is projected to produce 0.5 million pounds U3O8 in 2005. Approval was received in the third quarter to increase the test mine's output to 0.8 million pounds U3O8. Construction to facilitate this increase is expected to be complete by year's end.

The regulatory authorities have approved the EA and design plan for the commercial facility to be located at Inkai, block 1. Initial foundation work at the main processing plant and well field drilling has begun. Commercial production is scheduled for 2007. The costs, net of sales proceeds from Inkai production, are capitalized until commercial production is achieved. We expect Inkai to ramp up to full production of 5.2 million pounds U3O8 per year by 2010.

Subject to executing formal amendments, Cameco has agreed in principle to increase its loan to the joint venture Inkai from $40 million (US) to a maximum of $100 million (US). We also agreed to reduce our financing fee from an effective 10% interest rate to one based on the three-month London inter bank offered rate (LIBOR) plus 2% (equal to 6.065% using the September 30, 2005 LIBOR rate). The earlier loan amount was based on constructing a smaller plant that would produce 2.6 million pounds annually. Repayment of the loan will begin when commercial production starts. Legal work continues on formalizing these amendments.

Conversion Services Results

Third Quarter

In the third quarter of 2005, revenue from our conversion business rose by 15% to $39 million compared to the same period in 2004 as a result of an 18% improvement in the realized price. Most conversion sales are at fixed prices and have not yet fully benefited from the recent significant increase in UF6 spot prices. The benefit of the improved price was partially offset by a 5% decline in sales volume. As the timing of deliveries of nuclear products within a calendar year is at the discretion of customers, Cameco's quarterly delivery patterns can vary significantly.

In the third quarter of 2005, our total cost of products and services sold, including DDR, was unchanged at $34 million. The 5% decrease in sales volume was offset by a higher unit cost of product sold. The unit cost rose by 5% compared to the third quarter of 2004 due primarily to higher costs for purchased conversion, which have trended up with the rise in the UF6 spot price.

In the third quarter of 2005, earnings before taxes from the conversion business increased by $5 million compared to the third quarter of 2004 while the gross profit margin increased to 13% from 0%. In the third quarter of 2004, earnings from the conversion business were impacted by the strike at the Port Hope facility.

Year to Date

In the first nine months of 2005, revenue from our conversion business declined by 3% to $95 million compared to the same period in 2004. A 16% improvement in the realized price during the period was offset by a 17% decline in sales volume. Most conversion sales are at fixed prices and have not yet fully benefited from the recent increase in UF6 spot prices.

The total cost of products and services sold, including DDR, was $73 million in 2005 compared to $76 million in 2004. This decrease reflects the 17% decline in deliveries, largely offset by a higher unit cost of product sold. The unit cost rose by 16% compared to the first nine months of 2004 due primarily to higher costs for purchased conversion, which have trended upward with the rise in the UF6 spot price. In 2005, the cost of purchased conversion has risen by about 50% compared to the first nine months of 2004, due to purchases made to replenish inventory drawn down as a result of last year's strike at the Port Hope facility. The timing of conversion services deliveries vary significantly within a calendar year. In 2005, 40% of the conversion services sales are expected to occur in the fourth quarter.

In the first nine months of 2005, earnings before taxes from the conversion business were unchanged at $21 million while the gross profit margin increased to 23% from 22% in 2004.

Conversion Services Outlook for the Year

Revenue from the conversion business is expected to be marginally higher than in 2004 due to an expected 10% increase in the average realized selling price partially offset by a forecast 4% reduction in deliveries. Conversion sales volume is expected to total about 16.3 million kilograms of uranium (kgU) in 2005 compared to 16.9 million kgU in 2004. Production for 2005 is projected to be about 11.6 million kgU, up from 9.5 million kgU in 2004. As a result, unit costs for produced conversion are expected to be lower than in 2004.

Conversion Services Outlook for Fourth Quarter 2005

For the fourth quarter of 2005, our conversion revenue is projected to be about 50% higher than in the third quarter of 2005 due to increased deliveries. Gross profit is expected to rise significantly as a result of conversion production returning to normal levels after the summer maintenance shutdown.

Conversion Services Price Sensitivity Analysis

The majority of conversion sales are at fixed prices with inflation escalators. In the short term, Cameco's financial results are relatively insensitive to changes in the spot price for conversion. The newer fixed-price contracts generally reflect longer-term prices at the time of contract award. Therefore, in the coming years, our contract portfolio will be positively impacted by these higher fixed-price contracts.

Conversion Services Operations Update

Production

Port Hope production for the third quarter of 2005 was 2.4 million kgU compared to no production in the third quarter of 2004 because of the strike last year. Production in the third quarter of 2005 was lower than expected as a consequence of an extended maintenance shutdown and a difficult restart of the UF6 plant due mainly to the hot and humid weather during the summer months. Production for the first nine months of 2005 was 8.6 million kgU, up 21% from 7.1 million kgU for the same period in 2004.

Cameco expects to produce 11.6 million kgU for the year, below the target of 13.5 million kgU. We produced 9.5 kgU in 2004 when production was affected by a strike.

Slightly Enriched Uranium (SEU) Project Update

During the quarter, Cameco announced a decision not to pursue the blending of SEU in Port Hope. We determined it was necessary to seek alternative supply sources because it was not certain that the Port Hope conversion facility would be able to supply SEU in time to meet Bruce Power's schedule for the new fuel. Three alternative suppliers for the blending services were identified.

Third Quarter

Earnings Before Taxes

In the third quarter of 2005, Bruce Power recorded earnings of $307 million before taxes, up from $81 million for the third quarter of 2004. The increase reflects higher revenue due to high electricity prices during the period. Cameco's pre-tax earnings from Bruce Power amounted to $97 million compared to $28 million in 2004.

Output

Bruce Power achieved a capacity factor of 88% in the third quarter of 2005 compared to 85% in the same period of 2004. The increase primarily reflects fewer planned outage days in the quarter compared with the same period in 2004, when all four Bruce B units were taken off-line in mid-September for a vacuum building outage. During the third quarter of 2005, the Bruce Power units generated 9.1 terawatt hours (TWh) of electricity compared to 8.7 TWh in 2004.

Outlined below are the maintenance activities that occurred during the third quarter of 2005.

---------------------------------------------------------------------
Planned Outages
---------------------------------------------------------------------
Bruce B Unit 7    - Returned to service on Aug. 13 following a
                    planned inspection that began May 7 to complete
                    major spacer relocation work and turbine
                    replacement.
---------------------------------------------------------------------
Unplanned Outages
---------------------------------------------------------------------
Bruce B Unit 7    - The planned outage referenced above included an
                    11-day unplanned outage extension.
---------------------------------------------------------------------
Bruce A Unit 3    - Returned to service on Sept. 18 following an
                    outage that began Sept. 7 to repair the reactor
                    regulating system.
---------------------------------------------------------------------
---------------------------------------------------------------------

During the third quarter of 2005, the Bruce Power reactors were offline for a total of 55 days (32 planned and 23 unplanned). In the third quarter of 2004, Bruce Power experienced 55 reactor days of planned maintenance and 13 days of unplanned outages.

Price

For the third quarter of 2005, Bruce Power's revenue increased to $642 million from $395 million over the same period in 2004.

The realized price achieved from a mix of contract and spot sales averaged $70 per megawatt hour (MWh) in the third quarter, higher than the $45 per MWh realized in 2004.

During the quarter, the Ontario electricity spot price averaged $86 per MWh, compared to $46 per MWh in the third quarter of 2004. The higher prices in 2005 were due to an increase in demand as a result of warm weather.

To reduce its exposure to spot market prices, Bruce Power has a portfolio of fixed-price sales contracts. During the third quarter of 2005, about 40% of Bruce Power's output was sold under fixed-price contracts compared to 45% in the same period in 2004.

Cameco provides guarantees to customers under these contracts of up to $152 million. At September 30, 2005, our actual exposure under these guarantees was $133 million. In addition, we provide financial assurances for other Bruce Power commitments, which totalled about $82 million at September 30, 2005.

Costs

Operating costs (including amortization) were $317 million in the third quarter of 2005, compared with $297 million in the same period of 2004.

About 95% of Bruce Power's operating costs are fixed. As such, most of the costs are incurred whether the plant is operating or not. On a per MWh basis, the operating cost in the third quarter of 2005 was $35 per MWh, compared with $34 per MWh in the third quarter of 2004.

Year to Date

Earnings Before Taxes

For the nine months ended September 30, 2005, Bruce Power earnings before taxes were $435 million compared to $345 million in 2004. This increase primarily reflects higher realized electricity prices as a result of strong demand brought on by warmer weather, partially offset by a 5% decrease in capacity factor compared with the same period in 2004. Year to date, Cameco's earnings before tax from Bruce Power amounted to $141 million compared to $119 million for the same period in 2004.

Output

For the first nine months of the year, the Bruce Power units achieved a capacity factor of 80%, compared with 85% in the same period last year. These units produced 24.6 TWh during the first nine months of the year, a decrease of 1.5 TWh over the same period last year. This decrease reflects the planned outages of A3, A4 and B7 as well as other unplanned outages, primarily the 29-day outage of B6 to replace its main output transformer.

Price

For the first nine months of 2005, revenues totalled $1,453 million, compared to $1,228 million in the first nine months of 2004. During this period, Bruce Power's realized price averaged $58 per MWh from a mix of contract and spot sales compared with $46 per MWh during the same period last year. The Ontario electricity spot price averaged about $67 per MWh during the first nine months of the year, compared to $50 per MWh a year ago.

During the first nine months of 2005, about 47% of Bruce Power's output was sold under fixed-price contracts, the same as during the first nine months of 2004.

Costs

For the first three quarters of 2005, operating costs were $966 million compared with $833 million in the same period in 2004. Though up from 2004, operating costs were better than expected primarily due to lower outage and fuel costs and lower depreciation expenses on capital projects brought into service.

About 95% of Bruce Power's operating costs are fixed. As such, most of the costs are incurred whether the plant is operating or not. On a per MWh basis, the operating cost in the first nine months of 2005 was $39 per MWh, compared with $32 per MWh for the same period in 2004. The increase is primarily due to planned and unplanned outages and related outage costs.

Bruce Power Outlook for 2005

The targeted average capacity factor for 2005 remains at 83% for Bruce A and B. The targeted average capacity factor for Bruce B for 2005 is 82%. There is one planned outage for the remainder of 2005 for Bruce Power's reactors. Bruce unit B5 was taken offline on October 8 for an inspection program that is expected to last up to two months.

Bruce Power earnings in 2005 are expected to be significantly higher than in 2004, given the relatively high spot price for electricity in Ontario over the third quarter. This outlook excludes the loss that was triggered by the completion of the Bruce A restructuring. Results remain sensitive to the Ontario electricity price and the operating performance of the Bruce Power units.

Bruce Power Outlook for Fourth Quarter 2005

Cameco's earnings from Bruce Power are expected to be significantly lower than in the third quarter of 2005 due to expected lower realized prices and not sharing in the results of the A units. This outlook excludes the loss that was triggered by the completion of the Bruce A restructuring. Planned outages in the fourth quarter are expected to total about 60 days, five days more than all the outages in the third quarter of 2005.

In addition, Cameco anticipates it will proportionately consolidate Bruce Power's results once the restructuring is complete. In the past, we have accounted for Bruce Power using the equity method. The move to this new method of accounting is driven by changes to the partnership agreement, which provide for joint control among the three major partners.

Electricity Price Sensitivity Analysis

For the remainder of 2005, about 37% of Bruce Power's planned output will be under fixed-price contracts when based on total site output. This number increases approximately to 58% based on Bruce B alone.

A $1.00 per MWh change in the spot price for electricity in Ontario would change Cameco's after-tax earnings from Bruce Power by about $1 million.

Bruce Power has 13 TWh sold under fixed-price contracts for 2006. This would represent about 45% of Bruce B's generation at a 100% utilization factor.

Nuclear Electricity Update

Bruce A1 and A2 Restart

Cameco confirmed on October 31 that the Bruce Power restructuring was completed.

Cameco maintains its existing 31.6% interest in the Bruce Power Limited Partnership (BPLP) which is responsible for the overall management of the site and holds a 31.6% beneficial interest in the four Bruce B reactors. However, Cameco no longer holds an interest in the four Bruce A reactors and will not invest in the planned $4.25 billion program to increase their output.

As part of the restructuring, BPLP paid a distribution to its limited partners. Cameco's share is $200 million. As previously announced, the restructuring will result in Cameco recording a loss of $63 million (Cameco's share after tax) subject to closing adjustments which may increase or decrease the amount. The loss will be recorded in the fourth quarter of 2005.

Cameco will continue to be the fuel procurement manager for the Bruce A and B units but will no longer have obligations to procure or supply uranium concentrates to the Bruce A reactors.

Ontario Electricity Market

Extreme weather, high oil and gas prices and inadequate hydro-electric generation pushed Ontario electricity spot prices to record levels two months in a row, climbing over $93 per MWh in September. During the quarter, the Ontario government restated its commitment to the retirement of coal capacity while at the same time announcing, in conjunction with OPG, that there was no economic justification for returning Pickering A-2 and A-3 reactors to service.

GOLD

Cameco owns about 53% of Centerra, which is listed on the Toronto Stock Exchange (TSX). Centerra began trading on the TSX under the symbol CG in June 2004. We transferred substantially all of our gold assets to Centerra as part of our strategy to unlock the value contained in these gold properties.

The operating results of Kumtor Gold Company (Kumtor) have been fully consolidated as of June 22, 2004. Prior to that, we proportionately consolidated our interest in Kumtor. We also fully consolidate the results of Boroo, Centerra's gold mine in Mongolia. We adjust for a 47% minority interest in Centerra, which reflects that share of earnings attributable to shareholders other than Cameco.

Gold Results

Third Quarter

In the third quarter of 2005, revenue from the gold business declined by $21 million to $94 million compared to the third quarter of 2004. This decrease was due to lower gold production at the Kumtor mine. The realized price for gold increased to $429 (US) in the quarter compared to $398 (US) per ounce in the third quarter of 2004, due to higher spot prices.

For the quarter, the gross profit margin for gold declined to 25% from 37% in 2004 due to higher costs at Kumtor, largely the result of the lower production. On a 100% basis, Kumtor's production was 123,000 ounces compared to 167,000 ounces in the third quarter of 2004. This decrease was due to a lower mill head grade that averaged 3.4 grams per tonne (g/t) compared to 4.3 g/t in 2004.

Production at Boroo was 71,000 ounces compared to 69,000 ounces in 2004. The average head grade of ore fed to the mill was 4.1 g/t compared to 5.3 g/t last year. In spite of the lower grade, production rose marginally due to a 22% increase in throughput.

Year to Date

In the first nine months of 2005, revenue from our gold business rose by $112 million to $324 million compared to 2004. This increase was due largely to the full consolidation of Kumtor's results. The realized price for gold increased to $423 (US) in 2005 compared to $380 (US) per ounce in 2004, due to higher spot prices.

While Centerra's 2005 gold sales are unhedged, gold revenue includes proceeds from the sale of gold in the current period as well as deferred charges related to closed hedge contracts. The recognition of the deferred charges causes the realized gold price to vary relative to the average spot price for the period. In 2005, the deferred charges amounted to $7 per ounce compared to $17 per ounce in 2004.

Gold production at Kumtor was 403,000 ounces in the first nine months of 2005, 22% lower than in 2004 due mainly to a lower mill head grade that averaged 3.6 g/t compared to 4.6 g/t last year.

Boroo gold production in the first nine months of 2005 was 218,000 ounces compared to 151,000 ounces in 2004 due to a full nine months of production. The average head grade of ore fed to the mill was 4.4 g/t compared to 4.6 g/t last year.

Gold Market Update

The average spot market gold price during the third quarter of 2005 was $440 (US) per ounce, ending the quarter at $473 (US) per ounce. The average spot market gold price during the third quarter of 2004 was $401 (US) per ounce.

Timing differences between the settlement and designation of hedge contracts have resulted in deferred charges. At September 30, 2005, these deferred charges to be recognized in future periods totalled $4 million (US), including $1 million (US) in the remaining three months of 2005.

Gold Outlook for the Year

Based on Centerra's current operations, total production for the year is forecast at 800,000 ounces, a decline of almost 12% from 2004 primarily as a result of lower grades at the Kumtor mine. However, Centerra's beneficial production is expected to increase to 784,000 ounces from 610,000 in 2004 due to the increased ownership level in both mines and a full year of operation at Boroo.

At Kumtor, production in 2005 is expected to decline to 513,000 ounces from 657,000 ounces in 2004, due to a lower mill head grade that is expected to average 3.4 g/t compared to 4.4 g/t in 2004.

For Boroo, the outlook for 2005 calls for production to increase to 285,000 ounces from 246,000 ounces in 2004 due to higher throughput level. The mill head grade is expected to average 4.2 g/t compared to 4.5 g/t in 2004.

Overall, gold results are expected to decline in 2005 from 2004 due to higher unit costs and increased spending in exploration.

Gold Outlook for Fourth Quarter 2005

For the fourth quarter of 2005, profits from the gold business are projected to decline compared to the third quarter as a result of lower production from the Kumtor and Boroo mines where ore grades are expected to be lower than in the third quarter.

Gold Price Sensitivity Analysis

For 2005, gold sales are unhedged. For the remainder of 2005, a $10.00 (US) per ounce change in the gold spot price would change Cameco revenue by about $2 million (Cdn), cash flow by about $2 million (Cdn) and net earnings by about $1 million (Cdn).

Kyrgyz State Auditing Chamber Update

In its second quarter report, Centerra reported on requests for information from the Kyrgyz State Auditing Chamber. In the Chamber's recently-released report there are no issues that are expected to have material consequences for Centerra. Centerra has subsequently provided the authorities with further information in response to the report.

During the quarter, Centerra filed normal-course objections to the Kyrgyz tax and customs assessments received during the second quarter. Following arguments presented by Centerra, the tax authorities reversed the previous denial of loss carry-forwards that would have had a negative cash tax effect of $12 million over a three-year period. The outcome of the other tax audit objections, currently under consideration by the tax authorities, is not expected to have a material impact on Centerra's financial position.

Discussions with customs audit officials regarding Centerra's formal objection notice filed during the third quarter are continuing. The impact of these proceedings, if any, is not determinable at this time.

COMPANY DEVELOPMENTS

Zircatec Precision Industries

On October 4, 2005, Cameco announced it is negotiating to acquire Zircatec Precision Industries, Inc. Zircatec manufactures metal components for nuclear fuel bundles at its plant in Cobourg, Ontario. A second plant in Port Hope, Ontario handles nuclear material and completes the fuel bundle fabrication process. A decision is expected by year-end.

NUCLEAR INDUSTRY DEVELOPMENTS

United States

In the US, the prospects for new nuclear power plants continue to improve.

US President George Bush signed into law the first national energy policy in more than 10 years. The policy contains provisions that encourage investment in new nuclear reactor construction. Companies constructing new plants will receive financial protection for delays beyond their control for the first six new reactors and a limited production tax credit for the first eight years of operation for the first 6,000 megawatts built.

Ten entities have expressed an interest in proceeding with applications for either early site permits (ESP) or combined construction and operating licence (COL) for a potential new nuclear power plant. Three ESP applications are currently under review by the US Nuclear Regulatory Commission, one is being developed and four others have indicated they will go straight to a COL. An early site permit does not guarantee automatic approval for a new reactor, but verifies a site's suitability, environmental impact, and emergency planning concerns. Obtaining an early site permit should simplify the application process when a utility files for a COL and would be valid for 20 years, with the potential to be renewed for another 20 years. The COL process will provide an accurate estimate of costs for building and operating a new nuclear plant. Several potential sites and reactor types have been identified with the potential for a new reactor to be completed as early as 2014.

A public opinion poll conducted in August on behalf of the US Nuclear Energy Institute indicates continued public support for new US nuclear power plants. Residents living within 16 kilometres of an operating nuclear power plant were surveyed with the results indicating 83% favour nuclear energy and 76% are willing to see a new reactor built at an existing site near them.

Licence extensions continue, with a total of 35 US reactors granted 20-year licence extensions, while extensions for 39 more reactors have been applied for or their operators have indicated they intend to apply for life extensions. This amounts to over 70% of all US reactors.

The US government has announced it will contribute an excess quantity of military highly enriched uranium (HEU) to an international fuel reserve in order to prevent the spread of enrichment technology without discouraging the expansion of nuclear power. The fuel reserve is part of a larger back-up supply mechanism designed to ensure reliable access to nuclear fuel at a reasonable cost in the event of supply disruptions in the commercial market for nations that forego enrichment and reprocessing. Material from the fuel reserve could be released to US fuel suppliers at market rates if the International Atomic Energy Agency (IAEA) requested access for an eligible country suffering fuel supply disruptions. The 17.4 tonnes of US HEU, containing the equivalent of 7.6 million pounds U3O8, will be blended down to low enriched uranium over the next four years and is expected to be available for the fuel reserve in 2009. Previously, this material was expected to be made available to the commercial market.

The US has also announced plans to end nuclear sanctions on India, which would enable the country to buy nuclear fuel as well as civilian reactor technology from the US and possibly other nations. In return, India would have to place its civilian nuclear facilities under the supervision of the International Atomic Energy Agency. India would not sign the Nuclear Non-proliferation Treaty and its military nuclear facilities would still remain closed to inspections. India would maintain a moratorium on the testing of nuclear weapons and agree to keep up its non-proliferation efforts. India currently has over 3,300 megawatts of nuclear generating capacity and has announced plans to increase this to 20,000 megawatts by 2020, but does not have economic domestic uranium supply capable of supporting such a nuclear program. The removal of the sanctions could provide an additional market for nuclear fuel suppliers, equivalent to about 9 million pounds U3O8 per year by 2020. India currently consumes about 1.2 million pounds annually.

Canada

The Province of New Brunswick will proceed with refurbishing its only reactor, a 680 MWe Candu, which started operations in 1983 and was scheduled to close in 2008. The refurbishment will start in April 2008 and be completed by September 2009, prolonging the life of the unit by about 25 years. The cost of the project, including purchasing replacement electricity, is estimated at $1.4 billion.

The Canadian utility OPG has commenced the process of restarting its newly refurbished Pickering A-1 nuclear unit. The 515 MWe Candu last operated in December 1997. Work on the unit began in the summer of 2004 at a projected cost of $1.0 billion. OPG also announced that it will not proceed with the refurbishment of Pickering units A-2 and A-3 but will instead focus on maximizing the performance of its existing nuclear units.

Europe

France's utility has announced plans to begin to build at least one European pressurized water reactor (EPR) a year starting in 2020 to replace most of its existing 58 pressurized water reactors. It cited economic performance, stability of costs, and respect for environmental constraints as the basis for its decision. A demonstration EPR is scheduled to begin construction in 2007.

The Netherlands has reversed its policy of closing down its only nuclear reactor by 2013 and has granted a 20-year life extension allowing the unit to operate for a total of 60 years until 2033. The United Kingdom has granted 10-year life extensions to two of its units allowing operations until 2018. Licence extensions for other units are being pursued.

In Germany, the September federal elections failed to result in a majority win for the pro-nuclear opposition leader who had promised to reconsider the phase-out of nuclear power in that country. A coalition is being negotiated with an agreement expected in November, but it is unlikely that a coalition government will be able to undertake any pro-nuclear initiatives in the near term.

Other

The World Nuclear Association (WNA) has published its bi-annual nuclear fuel supply and demand report, which details three supply and three demand scenarios for uranium. The WNA forecasts that over the period 2005 through 2030, the world demand for uranium is expected to increase at an annual rate of about 3% in the reference case and 6% in the upper case.

On the supply side, the report concludes that for the reference case there is sufficient potential supply available to meet demand through 2015, but expresses concern about a shortfall after that time. The report assumes significant uranium supply comes in a timely manner from sources not yet identified and does not consider costs of production. For example, it assumes uranium from dismantled Russian weapons will continue to enter the market after the existing agreement expires in 2013, and production from a number of mines that still require feasibility studies and/or development decisions. Overall, the report is generally consistent with Cameco's view that additional primary supply will be needed to meet rising demand. The largest difference is that our analysis takes into consideration the prices required to bring on new capacity, while the WNA cannot due to the composition of its membership, which includes many fuel suppliers.

LIQUIDITY AND CAPITAL RESOURCES

Changes in liquidity and capital resources during the third quarter included the following:

Commercial Commitments

Commercial commitments at September 30, 2005 increased by 15% to $416 million from $363 million at June 30, 2005. Our obligations to provide financial guarantees supporting Bruce Power increased by $56 million, while standby letters of credit decreased by $3 million to the end of the quarter. At September 30, 2005, commercial commitments included standby letters of credit of $201 million and financial guarantees for Bruce Power of $215 million.

Credit Ratings

On August 26, 2005, Moody's Investors Service (Moody's) downgraded Cameco's senior unsecured debt rating to Baa2 from Baa1. As of September 30, 2005, we had the following ratings for our senior debt from third-party rating agencies:

- Dominion Bond Rating Service Limited (DBRS) - "A (low)" with a stable outlook

- Moody's Investors Service (Moody's) - "Baa2" with a stable outlook

- Standard & Poor's (S&P) - "BBB+" with a stable outlook

Debt

On September 16, 2005, Cameco issued $300 million of 10-year, 4.7% unsecured debentures, with the net proceeds applied principally to retiring outstanding commercial paper, planned capital expenditures and general corporate purposes.

Cameco has $50 million outstanding in senior unsecured debentures that bear interest at 7% and will mature on July 6, 2006. We also have $100 million outstanding in senior unsecured debentures that bear interest at 6.9% and will mature on July 12, 2006. As these debentures mature within the next year, they have been classified on the balance sheet as current obligations. We do not expect any difficulties in meeting these obligations by their respective maturity dates.

In addition to cash from operations, debt is used to provide liquidity. Cameco has sufficient borrowing capacity to meet its current requirements.

Cameco has access to about $742 million in unsecured lines of credit. Commercial lenders have provided a $500 million five-year unsecured revolving credit facility, available until November 30, 2010, with annual extension provisions. Up to $100 million of this facility can be used to support letters of credit. The facility ranks equally with all of Cameco's other senior debt. At September 30, 2005, there were no amounts outstanding under these credit facilities.

Cameco may borrow directly from investors by issuing commercial paper up to a maximum of $400 million. To the extent necessary, we use the revolving credit facility to, among other things, provide liquidity support for its commercial paper program. At September 30, 2005, there were no amounts outstanding under the commercial paper program.

Cameco also has agreements with various financial institutions to provide up to $242 million in short-term borrowing and letter of credit facilities. These arrangements are predominantly used to fulfill regulatory requirements to provide financial assurance for future reclamation of our operating sites. Outstanding letters of credit at September 30, 2005 amounted to $201 million.

SHARE CAPITAL

At September 30, 2005, there were 174.4 million common shares and one Class B share outstanding. In addition, there were 4.8 million stock options outstanding with exercise prices ranging from $5.00 to $54.08 per share. Cameco also had convertible debentures in the amount of $230 million outstanding. This issue may be converted into a total of 10.6 million common shares at a conversion price of $21.67 per share. The debentures are redeemable by Cameco beginning on October 1, 2008 at a redemption price of par plus accrued and unpaid interest. At current share prices, we expect existing holders to convert to equity.

RELATED PARTY TRANSACTIONS

Cameco buys a significant amount of goods and services for its Saskatchewan mining operations from northern Saskatchewan suppliers to support economic development in the region. One such supplier is Kitsaki Management Limited Partnership. Harry Cook, a director of Cameco, was the chair of this company and was also the chief of Lac LaRonge Indian Band, which owns Kitsaki. In the first nine months of 2005, we paid Kitsaki subsidiary companies $22.7 million for transportation and catering services. Chief Cook retired as chief of the Lac La Ronge Indian Band and chair of Kitsaki as of March 31, 2005. Mr. Cook may continue to be affiliated with the Band and Kitsaki.

1. Accounting Policies

These consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles (GAAP) and follow the same accounting principles and methods of application as the most recent annual consolidated financial statements. Since the interim financial statements do not include all disclosures required by GAAP, they should be read in conjunction with Cameco's annual consolidated financial statements included in the 2004 annual report. Certain comparative figures for the prior period have been reclassified to conform to the current period's presentation.

(b) Financial Assurances

Cameco has provided the following financial assurances on behalf of the partnership, with varying terms that range from 2004 to 2018:

(i) Licensing assurances to Canadian Nuclear Safety Commission of $24,000,000.

(ii) Guarantees to customers under power sale agreements of up to $152,000,000. Cameco's actual exposure under these guarantees was $133,000,000 at September 30, 2005.

(iii) Termination payments to Ontario Power Generation Inc. pursuant to the lease agreement of $58,000,000.

(c) Subsequent Event

On October 31, 2005, a new Bruce A limited partnership was formed to hold the lease for the four Bruce A reactors. Cameco is not part of this new partnership but it has maintained its existing 31.6% interest in the Bruce Power Limited Partnership (BPLP), which will retain ownership of the four Bruce B reactors. BPLP will receive an initial payment for the assets transferred to the Bruce A partnership which will result in a special distribution to the partners. Cameco's share of the special distribution will be approximately $200,000,000.

The reorganization involving Bruce A triggers a loss of about $63,000,000 (Cameco's share after tax) subject to closing adjustments, which may increase or decrease the amount. This loss will be recognized in the fourth quarter.

3. Long-Term Debt

The fair value of the outstanding convertible debentures based on the quoted market price of the debentures at September 30, 2005 was approximately $688,000,000.

Cameco completed a $300,000,000 debt issuance on September 16, 2005 in the form of unsecured debentures. These debentures bear interest at a rate of 4.7% per annum and mature September 16, 2015.

Cameco has $50,000,000 outstanding in senior unsecured debentures that bear interest at a rate of 7.0% per annum and mature July 6, 2006. Cameco also has $100,000,000 outstanding in senior unsecured debentures that bear interest at a rate of 6.9% per annum and mature July 12, 2006. During the quarter, these amounts were reclassified from long-term to current.

4. Share Capital

(a) At September 30, 2005, there were 174,368,941 common shares outstanding.

(b) Options in respect of 4,758,340 shares are outstanding under the stock option plan and are exercisable up to 2015. Upon exercise of certain existing options, additional options in respect of 83,000 shares would be granted.

9. Stock-Based Compensation

Stock Option Plan

Cameco has established a stock option plan under which options to purchase common shares may be granted to directors, officers and other employees of Cameco. Options granted under the stock option plan have an exercise price of not less than the closing price quoted on the Toronto Stock Exchange (TSX) for the common shares of Cameco on the trading day prior to the date on which the option is granted. The options vest over three years and expire eight years from the date granted. Options granted prior to 1999 expire 10 years from the date of the grant of the option.

The aggregate number of common shares that may be issued pursuant to the Cameco stock option plan shall not exceed 15,730,209, of which 9,397,357 shares have been issued.

For the nine months ended September 30, 2005, Cameco has recorded compensation expense of $10,836,000 (2004 - $5,364,000) with an offsetting credit to contributed surplus to reflect the estimated fair value of stock options granted to employees in 2005.

Cameco has applied the pro forma disclosure provisions of the standard to awards granted on or after January 1, 2002 but prior to January 1, 2003. The pro forma effect of awards granted prior to January 1, 2002 has not been included. The pro forma net earnings, basic and diluted earnings per share after giving effect to the grant of these options in 2002 are:

Executive Performance Share Unit (PSU), Deferred Share Unit (DSU), and Other Plans

Commencing in 2005, Cameco provides each executive officer an annual grant of PSUs in an amount determined by the Board. Each PSU represents one phantom common share that entitles the participant to a payment of one Cameco common share purchased on the open market, or cash at the Board's discretion, at the end of each three-year period if certain performance and vesting criteria have been met. The final value of the PSUs will be based on the value of Cameco common shares at the end of the three-year period and the number of PSUs that ultimately vest. Vesting of PSUs at the end of the three-year period will be based on total shareholder return over the three years, Cameco's ability to meet its annual cash flow from operations targets and whether the participating executive remains employed by Cameco at the end of the three-year vesting period. As of September 30, 2005, the total PSUs held by the executive was 98,100.

Cameco offers a deferred share unit plan to non-employee directors. A DSU is a notional unit that reflects the market value of a single common share of Cameco. In the nine months ended September 30, 2005, sixty percent of each director's annual retainer was paid in DSUs. In addition, on an annual basis directors can elect to receive the remaining forty percent of their annual retainer and any additional fees in the form of DSUs. Each DSU fully vests upon award. The DSUs will be redeemed for cash upon a director leaving the board. The redemption amount will be based upon the weighted average of the closing prices of the common shares of Cameco on the TSX for the last twenty trading days prior to the redemption date multiplied by the number of DSUs held by the director. As of September 30, 2005, the total DSUs held by participating directors was 130,887 (September 30, 2004 - 114,550).

Cameco makes annual grants of bonuses to eligible non-North American employees in the form of phantom stock options. Options under this plan are not physically granted; rather employees receive the equivalent value of shares in cash when exercised. Options granted under the phantom stock option plan have an award value equal to the closing price quoted on the TSX for the common shares of Cameco on the trading day prior to the date on which the option is granted. The options vest over three years and expire eight years from the date granted. As of September 30, 2005, the number of options held by participating employees was 243,780 (September 30, 2004 - 348,300) with exercise prices ranging from $9.61 to $54.08 per share (September 30, 2004 - $9.61 to $21.03) and a weighted average exercise price of $23.53 (September 30, 2004 - $16.16).

Cameco has recognized the following amounts for these plans:

10. Goodwill

The acquisitions undertaken as part of the 2004 gold restructuring
were accounted for using the purchase method whereby assets and
liabilities assumed were recorded at their fair market value as of
the date of acquisition. The excess of the purchase price over such
fair value was recorded as goodwill. The change in goodwill is due
to the following:

---------------------------------------------------------------------
                                                          (thousands)

Balance, beginning of period                                $187,184

---------------------------------------------------------------------
---------------------------------------------------------------------

Cameco tests goodwill for possible impairment on an annual basis and at any other time if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. During the third quarter of 2005, Cameco completed the goodwill impairment test for all reporting units. The results of this test have indicated there is no impairment.

12. Commitments and Contingencies

(a) Cameco signed a toll-conversion agreement with British Nuclear Fuels plc (BNFL) to acquire uranium UF6 conversion services from BNFL's Springfields plant in Lancashire, United Kingdom. Under the 10-year agreement, BNFL will annually convert a base quantity of 5 million kgU as UO3 to UF6 for Cameco.

(b) In its financial statements for the second quarter of 2005, Cameco reported on the Kyrgyz tax authorities' state tax audit and customs audit of Centerra's 100% subsidiary, Kumtor Gold Company (Kumtor). During the quarter, Kumtor filed normal-course objections to the tax and customs assessments. Following arguments presented by Kumtor, the regulators reversed the previous denial of loss carry-forwards that would have had a negative cash tax effect of $12,000,000 over a three-year period. The outcome of the other tax audit objections, currently under consideration by the regulators, is not expected to have a material impact on Cameco's financial position.

Discussions with the customs audit officials regarding Kumtor's formal objection notice filed during the third quarter are continuing. We believe the outcome of these proceedings will not have a material impact on Cameco's financial position.

(c) In its financial statements for the second quarter of 2005, Cameco reported on requests for information from the State Auditing Chamber of the Kyrgyz Republic. The Chamber recently released its report. We believe none of the issues raised in the report will have a material impact on Cameco's financial position. Kumtor has subsequently provided the authorities with further information and documents in response to the report.

(d) A jury action was commenced by Oren Benton on November 28, 2000 in the State of Colorado, USA, against Cameco. The action claims in excess of $200,000,000 (US) for breach of contract, breach of duty of good faith and fair dealing, and tortuous interference with contractual relations and/or business expectations. Cameco's motion to dismiss the claim was granted by Senior Judge Daniel B. Sparr by order filed November 15, 2002 and Mr. Benton's claim was dismissed. Mr. Benton has unsuccessfully appealed this decision and his appeal to the Supreme Court of the United States was also denied.

On October 9, 2005, Oren Benton filed a claim in Regina, Saskatchewan. The claim is similar to the action he commenced in Colorado other than it does not specify an amount of damages claimed. Cameco believes the claim is without merit.

13. Related Party Transactions

The company purchases a significant amount of goods and services for its Saskatchewan mining operations from northern Saskatchewan suppliers to support economic development in the region. One such supplier is Kitsaki Management Limited Partnership (Kitsaki). Harry Cook, a director of Cameco, was the chair of the company and was also the chief of the Lac La Ronge Indian Band, which owns Kitsaki. In the nine months ended September 30, 2005, Cameco has paid Kitsaki subsidiary companies $22,700,000 (2004 - $18,500,000) for transportation and catering services. The transactions were conducted in the normal course of business and were accounted for at the exchange amount. Accounts payable include a balance of $1,854,000 (2004 - $536,000) resulting from these transactions.
