PRESS RELEASE Trading symbols: DML-T, DNN-A

DENISON MINES CORP. REPORTS SECOND QUARTER EARNINGS

Toronto, ON August 13, 2008 Denison Mines Corp. (Denison or the Company) (DML: TSX, DNN: AMEX) today reported its financial results for the three months and six months ended June 30, 2008. All amounts in this release are in U.S. dollars unless otherwise indicated. For a more detailed discussion of the financial results, see managements discussion and analysis (MD&A) following this release.

Consolidated Results

Consolidated net loss was $13,756,000 or $0.07 per share for the three months ended June 30, 2008 compared with consolidated net income of $40,489,000 or $0.21 per share for the same period in 2007. For the six months ended June 30, 2008, consolidated net loss was $24,218,000 ($0.13 per share) compared with consolidated net income of $35,423,000 ($0.19 per share) for the same period in 2007.

Revenue was $31,713,000 for the three months ended June 30, 2008 compared with $18,809,000 for the three months ended June 30, 2007. Revenue was $49,894,000 for the six months ended June 30, 2008 compared to $30,528,000 for the six months ended June 30, 2007.

Net cash from (used in) operations was ($5,952,000) for the three months ended June 30, 2008, compared with net cash from operations of $537,000 for the three months ended June 30, 2007. For the six months ended June 30, 2008 net cash from (used in) operations was $1,670,000 compared with ($4,905,000) for the same period in 2007.

Losses on foreign currency translation totaled $11,237,000 for the three months and $12,766,000 for the six months ended June 30, 2008 arising from the translation of the Zambian kwacha into U.S currency at June 30, 2008. Substantially all of this loss resulted from translating future income taxes payable relating to the Mutanga project.

In March 2008, the Zambian government enacted previously announced legislation which increased the income tax rate for mining companies from 25% to 30%. As a result in the first quarter the Company increased its future income taxes related to its Zambian assets thereby reducing net income by $10,740,000.

The Company expenses exploration expenditures on mineral properties not sufficiently advanced to identify their development potential. Exploration expenditures expensed totalled $3,787,000 for the three months ended and $10,352,000 for the six months ended June 30, 2008 compared to $3,480,000 for the three months and $8,529,000 for the six months ended June 30, 2007.

Significant events in the second quarter include:

| | Denison sold 100,000 pounds U 3 O 8 during the quarter from U.S.
production at an average price of $83.13 per pound and 271,950 pounds
U 3 O 8 from its Canadian production under the existing long-term
contracts at an average price of $50.96 per pound. |
| --- | --- |
| | Spot prices for U 3 O 8 decreased from $71.00 per pound at March 31,
2008 to $59.00 per pound at June 30, 2008 as quoted by Ux Consulting. The long-term price
for U 3 O 8 dropped from $95.00 per pound at March 31, 2008 to $80.00
per pound at June 30, 2008 as quoted by Ux Consulting. |
| | Denison purchased 5,465,000 common equity units in Uranerz Energy Corp., each unit
consisting of one common share and one-half warrant for $2.40 per unit or $13,116,000. |

Revenue

Uranium sales revenue for the second quarter was $28,998,000. Sales from U.S. production were 100,000 pounds U 3 O 8 at an average price of $83.13 per pound. Sales of Canadian production were 271,950 pounds U 3 O 8 at an average price of $50.96 per pound. Revenue also includes the amortization of the fair value increment on sales contracts from the acquisition of Denison Mines Inc. in the amount of $6,737,000 in the quarter. Uranium sales revenue in the 2007 period totaled $15,243,000 from the net sale of 70,000 pounds U 3 O 8 from Canadian production at an average sales price of $80.51 per pound and the sale of 75,000 pounds U 3 O 8 from U.S. production at an average price of $130.00 per pound.

Denison currently markets its uranium from the McClean Lake joint venture jointly with AREVA Resources Canada Inc. (ARC). Denisons share of current contracted sales volumes jointly marketed with ARC is set out in the table below:

	Contracted Canadian Sales Volumes
	(pounds U 3 O 8 x 1000)
(in thousands)	2008	2009	2010	Pricing
Market Related	588	392	49	80% to 85% of Spot
Legacy Base Escalated	95	0	0	$20.00 to $26.00
Legacy Market Related	60	0	0	96% of Spot

Agreements with AREVA call for production to be allocated first to the market related contracts with any surplus to be apportioned evenly over the legacy contracts. The legacy base-escalated contracts have pricing formulas that result in sales prices well below current market prices.

The joint marketing of Canadian uranium production will cease at the end of 2008 except for the market related category above. Future long-term sales agreements for the Companys uranium inventory and production are expected to be primarily under market-related contracts.

Revenue from the environmental services division was $1,354,000 for the three months ended June 30, 2008 compared to $1,174,000 in the same period in 2007. Revenue from the management contract with Uranium Participation Corporation was $1,347,000 for the three months ended June 30, 2008 compared to $2,129,000 for the second quarter of 2007.

Uranium Production

Total uranium production for the Company from its Canadian and U.S. operations was 322,000 pounds for the three months ended June 30, 2008 and 507,000 pounds for the six months ended June 30, 2008. The McClean Lake joint venture produced 1,157,000 pounds U 3 O 8 for the three months ended June 30, 2008 and 1,748,000 pounds U 3 O 8 for the six months ended June 30, 2008 compared to production of 329,000 pounds and 784,000 pounds during the same periods in 2007. Denisons 22.5% share of the 2008 production totaled 260,000 pounds during the three months and 393,000 pounds during the six months ended June 30, 2008.

Production at the White Mesa mill was 62,000 pounds U 3 O 8 for the three months ended June 30, 2008 and 114,000 pounds U 3 O 8 for the six months ended June 30, 2008 compared to 56,000 pounds and 137,000 pounds U 3 O 8 for the same periods in 2007. Processing of conventional ore commenced on April 28, 2008 and to June 30, 2008 production from conventional ore was 20,000 pounds U 3 O 8. Production at the White Mesa mill has been increasing since the commencement of conventional ore processing with approximately 89,500 pounds U 3 O 8 produced in July 2008.

PAGEBREAK

June 30, 2007. For the six months ended June 30, 2008, exploration expenditures totaled $10,352,000 compared with $8,529,000 for the six months ended June 30, 2007.

A majority of the exploration expenditures during the period were spent in the Athabasca Basin region of northern Saskatchewan. Denison is engaged in uranium exploration on advanced projects in this region of Canada as part of the ARC operated McClean and Midwest joint ventures and is participating in a total of 34 other exploration projects concentrated in the prospective eastern margin of the Athabasca Basin. Denisons share of exploration spending on its Canadian properties totaled $2,758,000 of which $2,546,000 was expensed in the statement of operations for the three months ended June 30, 2008. Exploration spending totaled $3,279,000 of which $3,059,000 was expensed in the statement of operations for the three months ended June 30, 2007. For the six months ended June 30, 2008, Denisons share of exploration spending on its Canadian properties totaled $9,168,000 of which $8,474,000 was expensed compared with spending of $8,433,000 of which $7,894,000 was expensed in the six months ended June 30, 2007.

Exploration expenditures of $1,090,000 for the three months ended June 30, 2008 ($319,000 for the three months ended June 30, 2007) and of $1,421,000 for the six months ended June 30, 2008 ($461,000 for the six month period in 2007) were spent in Mongolia on the Companys joint venture and 100% owned properties. The Company has a 70% interest in the Gurvan Saihan Joint Venture (GSJV) in Mongolia. The other parties to the joint venture are the Mongolian government as to 15% and Geologorazvedka, a Russian government entity, as to 15%. Additional expenditures for development of the GSJVs Hairhan uranium deposits have also been incurred. Development work includes extensive resource delineation drilling, hydrological drilling, plant design and environmental studies.

General and Administrative

General and administrative expenses were $4,674,000 for the three months ended June 30, 2008 compared with $3,558,000 for the three months ended June 30, 2007. The increase was primarily the result of a ramping up of the Companys operations, the acquisition and implementation of new information and financial systems, an increase in public company expenses due to additional compliance costs and an increase in non-cash stock compensation costs resulting from stock options granted in 2008. General and administrative expenses consist primarily of payroll and related expenses for personnel, contract and professional services and other overhead expenditures.

Other Income and Expenses

Other income (expense) totaled ($10,742,000) for the three months ended June 30, 2008 compared with $37,678,000 for the three months ended June 30, 2007. For the six months ended June 30, 2008, other income (expense) totaled ($8,516,000) compared to $38,236,000 for the same period in 2007. During the current period, this consists primarily of interest income, interest expense, and foreign exchange losses. Foreign exchange translation losses totaled $11,237,000 for the three months and $12,766,000 for the six months ended June 30, 2008 arising from the translation of the Zambian kwacha into the U.S. dollar. Substantially all of this loss is the result of the translation of future income taxes payable relating to the Mutanga project. In 2007, other income (expense) included a gain on the sale of portfolio investments of $38,643,000 for the three months and six month periods. Other income (expense) also included interest paid on company indebtedness of $516,000 for the three months and $519,000 for the six months ended June 30, 2008.

Outlook for 2008

1.2% V 2 O 5. At the Tony M mine within the Henry Mountains Complex, located in Utah, production is currently approximately 300 tons per day and will ramp up to 450 tons per day by year end. Production from these mines is being hauled to Denisons White Mesa mill. At June 30, 2008, a total of 191,000 tons had been shipped to the mill of which 49,000 tons have been fed to the mill. Mine development work had begun at the Companys Arizona 1 mine on the Arizona Strip located in northeastern Arizona. Shaft rehabilitation and ventilation raises are complete. Air quality permitting process is underway but the Company is unable to determine the length of time required to receive the permit. Ore production from this mine is now not anticipated until 2009.

Processing of conventional ore at the mill began on April 28, 2008. The mill processed uranium-only ore from the Tony M mine to June 30, 2008. On July 1, 2008, processing of the uranium/vanadium ores from the Companys Colorado Plateau mines commenced. The relining of tailings cell 4A is essentially complete. Approval of the operating permit for cell 4A is expected by mid- August, 2008. The start-up of the White Mesa mill has gone very well with throughput currently averaging 1,500 tons per day.

The Company expects to produce 1.0 to 1.2 million pounds U 3 O 8 and 2.9 to 3.2 million pounds V 2 O 5 during 2008 at the White Mesa mill.

Sales

The Company expects to sell 1.6 to 1.8 million pounds of U 3 O 8 in 2008 including 0.9 to 1.0 million pounds from U.S. production. It also anticipates selling 2.9 to 3.0 million pounds of vanadium. Vanadium prices are quite volatile but have recently risen to a level of $14 to $15 per pound V 2 O 5 from an average of $7.00 to $8.00 per pound in 2007. Most of Denisons sales of uranium and vanadium from U.S. production will occur in the third and fourth quarters of the year.

Exploration 1

Athabasca Basin

In the Athabasca Basin, Denison is participating in 36 exploration projects, primarily located in the eastern part of the Basin and within trucking distance of all the three operating mills in the area. Denison and its joint venture partners carried out an extensive exploration program during this quarter.

On the 60% owned Wheeler River property, the first hole of the summer program, WR-249, discovered a new zone of unconformity mineralization in an area not previously tested, and returned very intense sandstone alteration surrounding an assay of 0.263% eU 3 O 8 over 2.0 metres from the unconformity at a depth of approximately 400 metres. Subsequent to the quarter, a further hole, 600 metres along the geophysical strike, returned similar intensely altered unconformity related mineralization and with a probe grade of 0.248 % eU 3 O 8 over 2.8 metres.

Denisons exploration spending in 2008 in the Athabasca Basin is expected to total $15,300,000.

Southwest United States

Near the end of the quarter Denison received approvals to begin exploration drilling on some of the Companys properties on the Colorado Plateau. Drilling began early in the third quarter on the Monogram Mesa project. Denison is planning on spending $2,000,000 on its U.S. exploration program this year, drilling an estimated 149,000 feet (45,000 metres). The program will be focused on exploring near its existing operations on the Colorado Plateau.

1 The grades reported herein are equivalent U 3 O 8 grades based on down hole radiometric probing at a cut-off grade of 0.05% eU; geochemical corroborative assay results have not been completed at this time. All intersections and geological interpretations are based on diamond drill core only and mineralized intervals may not represent true thickness. For a description of the quality assurance program and quality control measures applied by both ARC and Denison during the above described work, please see Denisons Annual Information Form filed under the Companys profile on March 28, 2008 on the SEDAR website at www.sedar.com.

The technical information contained in this press release relating to the above described exploration activities is reported and verified by William C. Kerr, Denisons Vice-President, Exploration, who is a qualified person as defined in National Instrument 43-101.

Mongolia

In Mongolia, fieldwork is well underway and on schedule on six projects. Fifteen large diameter core holes were drilled at the main part of the Haraat deposit to provide samples for metallurgical testwork, which is underway and has shown promising recoveries based on results to date. Exploration and development drilling commenced on the Hairhan, Gurvan Saihan, and Ulziit depressions and production was on target, with almost 34,000 metres of the scheduled 85,000 metres completed by the end of the quarter. Most of the work completed at Hairhan was in support of resource definition in advance of a NI 43-101 report, expected to be completed in early fall. Hydrological drilling for baseline monitoring and test wells at the Hairhan deposit, in support of the planned ISR pilot plant next year, was also initiated. The Company expects to spend $11.5 million in Mongolia in 2008.

Zambia

In Zambia, development drilling has been ongoing since the start of the year, where a total of 37,456 metres has been drilled in 2008, primarily on the Mutanga and Dibwe proposed pits and extensions. It is anticipated that a new NI 43-101 report on the Mutanga and Dibwe resources will be completed during the third quarter.

A large scale exploration program outside of the resource areas has commenced. A total of 66 line kilometres out of 267 have been cut and a 9,000 kilometre helicopter supported spectrometer survey has begun. In addition to the geophysical surveys, two drills have begun drilling exploration targets along the corridor between the Mutanga and Dibwe deposits. Subsequent to the quarter, a drill hole testing a new area near the Mutanga deposit returned an intersection of 69.1 metres of 436 ppm eU 3 O 8 . This drill hole represents one of the best intercepts from any hole on the Mutanga project. A third drill will also begin drilling exploration targets upon the completion of a hydrological drill program which is being done as part of the overall project work.

Metallurgical testwork on the large sample delivered to Perth in the previous quarter is underway. The Mutanga programs will cost about $23,100,000 in 2008.

Liquidity

The Company had cash and cash equivalents at June 30, 2008 of $7,388,000 and portfolio investments with a market value of $66,429,000. The company has put in place a $125,000,000 revolving credit facility with a term of three years. Bank indebtedness under a temporary facility at June 30, 2008 was $65,527,000.

Objectives for 2008

The Company had set the following objectives for 2008:

	Increase U 3 O 8 production by over 200% to 2.1 to 2.4 million pounds
	Produce 3.0 to 4.0 million pounds of vanadium (V 2 O 5 )
	Sell 1.7 million pounds U 3 O 8 and 3.0 million pounds
V 2 O 5 at or near market prices
	Develop three new near-term projects: Midwest, Mongolia and Mutanga
	Pursue aggressive exploration program for long-term growth
	Attract and retain great people

The Company believes it is on track to meet these objectives except for the production which is now estimated at 1.7 to 1.9 million pounds U 3 O 8 and 2.9 to 3.2 million pounds V 2 O 5 .

Sales of Canadian production were 271,950 pounds U 3 O 8 at an average price of $50.96 per pound. Amortization of the fair value increment related to long term contracts from the acquisition of Denison Mines Inc. (DMI) totaled $6,737,000 for the second quarter. Reported revenue is also impacted by the effect of foreign currency translations.

For the six months ended June 30, 2008, uranium sales revenue totaled $45,176,000 consisting of sales of 150,000 pounds U 3 O 8 from U.S. production at an average price of $85.50 and sales of 418,950 pounds of production from the McClean Lake joint venture at an average price of $58.18 per pound. Amortization of the fair value increment related to long term sales contracts from the acquisition of DMI totaled $7,642,000.

Uranium sales revenue for the same periods in 2007 totaled $15,243,000 for the three months and $23,556,000 for the six months ended June 30, 2007 from the sale of 70,000 pounds U 3 O 8 and 185,000 pounds U 3 O 8 from Canadian production and sales of 75,000 pounds U 3 O 8 from U.S. production all in the second quarter. Amortization of the fair value increment from DMI sales contracts was ($143,000) and $1,009,000 respectively.

Denison currently markets its uranium from the McClean Lake joint venture jointly with AREVA Resources Canada Inc. (ARC). Denison share of current contracts sales volumes jointly marketed with ARC is set out in the table below:

Operating Expenses

Milling and Mining Expenses

The McClean Lake joint venture produced 1,157,000 pounds U 3 O 8 for the three months ended June 30, 2008 and 1,748,000 pounds U 3 O 8 for the six months ended June 30, 2008 compared with 329,000 pounds U 3 O 8 for the three months and 784,000 pounds U 3 O 8 for the six months ended June 30, 2007. Denisons 22.5% share of production totaled 260,000 pounds and 393,000 pounds respectively for the 2008 periods and 74,000 pounds and 176,000 pounds respectively for the 2007 periods.

Unit production cash costs in Canada are driven primarily by production volumes as the majority of costs do not vary with volume. These fixed costs for the McClean operations total approximately Cdn$46 million per year so as production volumes increase, the cost per pound decreases. Reagent costs are in addition to this cost as are amortization, depletion and depreciation costs. Production by the joint venture in 2008 is expected to be 3.2 million pounds U 3 O 8.

The Company began processing conventional ore at the White Mesa mill on April 28, 2008. Production from conventional ore to June 30, 2008 was 20,000 pounds U 3 O 8. Production from alternate feed milling was 42,000 and 94,000 pounds U 3 O 8 for the three months and six months ended June 30, 2008 compared to 56,000 and 137,000 pounds U 3 O 8 for the same periods in 2007. Total production at the White Mesa mill was 62,000 pounds U 3 O 8 and 114,000 pounds U 3 O 8 for the three months and six months ended June 30, 2008.

Sales Royalties and Capital Taxes

Sales royalties and capital taxes totaled $999,000 and $1,808,000 for the three and six months ended June 30, 2008 compared with $436,000 and $981,000 for the same periods in 2007. Denison pays a Saskatchewan basic uranium royalty of 4% of gross uranium sales after receiving the benefit of a 1% Saskatchewan resource credit. Denison also pays Saskatchewan capital taxes based on the greater of 3.1% of gross uranium sales or capital tax otherwise computed under the Saskatchewan Corporation Capital Tax Act. The Saskatchewan government also imposes a tiered royalty which ranges from 6% to 15% of gross uranium sales after recovery of mill and mine capital allowances which approximate capital costs. Denison has sufficient mill and mine capital allowances available or anticipated to shelter it from the tiered royalty at current uranium prices for at least 2008.

MINERAL PROPERTY EXPLORATION

Denison is engaged in uranium exploration, as both operator and non-operator of joint ventures and as operator of its own properties in Canada, the U.S., Mongolia and Zambia. For the three months ended June 30, 2008 exploration expenditures totaled $3,787,000 compared to $3,480,000 for the three months ended June 30, 2007. For the six months ended June 30, 2008 exploration expenditures totaled $10,352,000 compared with $8,529,000 for the six months ended June 30, 2007.

A majority of the exploration expenditures during the period were spent in the Athabasca Basin region of northern Saskatchewan. Denison is engaged in uranium exploration on advanced projects in this region of Canada as part of the ARC operated McClean and Midwest joint ventures and is also participating in a total of 34 other exploration projects concentrated in the prospective eastern margin of the Athabasca Basin. Denisons share of exploration spending on its Canadian properties totaled $2,758,000 of which $2,546,000 was expensed in the statement of operations for the three months ended June 30, 2008. For the three months ended June 30, 2007, exploration spending totaled $3,279,000 of which $3,059,000 was expensed. For the six months ended June 30, 2008, Denisons share of exploration spending on its Canadian properties totaled $9,168,000 of which $8,474,000 was expensed compared with spending of $8,433,000 of which $7,894,000 was expensed in the six months ended June 30, 2007.

Exploration expenditures of $1,090,000 for the three months ended June 30, 2008 ($319,000 for the three months ended June 30, 2007) and of $1,421,000 for the six months ended June 30, 2008 ($461,000 for the six month period in 2007) were incurred in Mongolia on the Companys joint venture and 100% owned properties. The Company has a 70% interest in the Gurvan Saihan Joint Venture (GSJV) in Mongolia. The other parties to the joint venture are the Mongolian government as to 15% and Geologorazvedka, a Russian government entity, as to 15%. Additional expenditures for development of the GSJVs Hairhan uranium deposits have also been incurred. Development work includes extensive resource delineation drilling, hydrological drilling, plant design and environmental studies.

General and Administrative

General and administrative expenses totaled $4,674,000 for the three months ended June 30, 2008 compared with $3,558,000 for the three months ended June 30, 2007. For the six months ended June 30, 2008, general and administrative expenses totaled $8,794,000 compared to $6,460,000 for the same period in 2007. The increase was primarily the result of the acquisition and implementation of new information and financial systems, an increase in public company expenses due to additional compliance costs and an increase in stock based compensation costs resulting from stock options granted in 2008. General and administrative expenses consist primarily of payroll and related expenses for personnel, contract and professional services and other overhead expenditures.

Other Income and Expenses

and $12,766,000 for the six months ended June 30, 2008 arising from the translation of the Zambian kwacha to U.S. dollars. This is primarily the result from translating future income taxes payable relating to the Mutanga project. In 2007, other income (expense) was primarily due to a gain on the sale of portfolio investments which totaled $38,643,000 for the three months and six month periods in 2007.

Other income included interest paid on company indebtedness of $516,000 for the three months and $519,000 for the six months ended June 30, 2008.

Income Taxes

The Company has provided for a current tax recovery of $1,590,000 and for a future tax expense of $8,547,000. In March, 2008, the Zambian government enacted legislation which increased the income tax rate for mining companies from 25% to 30%. Accordingly, the Company recorded a future tax expense of $10,740,000 in the first quarter to adjust the future income tax liability. This amount has been partially offset by the recognition of previously unrecognized Canadian tax assets of $3,700,000.

Outlook for 2008

Mining and Production

Canada

Mining of the Sue B deposit, which contains approximately 1.4 million pounds U 3 O 8 , has commenced. Milling of the stockpiled Sue E ore is ongoing and U 3 O 8 production at McClean Lake in 2008 is expected to be 3.2 million pounds of which Denisons share is 720,000 pounds.

United States

Five mines are operating on the Colorado Plateau with production from the Sunday, Pandora, Topaz, West Sunday and Rim mines running at about 400 tons per day. Head grades to the end of July have been slightly lower than planned averaging 0.18% U 3 O 8 and 1.05% V 2 O 5 compared to plan of 0.2% U 3 O 8 and 1.2% V 2 O 5. At the Tony M mine within the Henry Mountains Complex, located in Utah, production is currently approximately 300 tons per day and will ramp up to 450 tons per day by year end. Production from these mines is being hauled to Denisons White Mesa mill. At June 30, 2008, a total of 191,000 tons had been shipped to the mill of which 49,000 tons have been fed to the mill. Mine development work had begun at the Companys Arizona 1 mine on the Arizona Strip located in northeastern Arizona. Shaft rehabilitation and ventilation raises are complete. Air quality permitting process is underway but the Company is unable to determine the length of time required to receive the permit. Ore production from this mine is now not anticipated until 2009.

The Company expects to produce 1.0 to 1.2 million pounds U 3 O 8 and 2.9 to 3.2 million pounds V 2 O 5 during 2008 at the White Mesa mill.

Sales

The Company expects to sell 1.6 to 1.8 million pounds of U 3 O 8 in 2008 including 0.9 to 1.0 million pounds from U.S. production. It also anticipates selling 2.9 to 3 million pounds of vanadium. Vanadium prices are quite volatile but have risen to a level of $14 to $15 per pound V 2 O 5 from an average of $7.00 to $8.00 per pound in 2007. Most of Denisons sales of uranium and vanadium from U.S. production will occur in the third and fourth quarters of the year.

Exploration 1

Athabasca Basin

On the 60% owned Wheeler River property, the first hole of the summer program, WR-249, discovered a new zone of unconformity mineralization in an area not previously tested, and returned very intense sandstone alteration surrounding an assay of 0.263% eU 3 O 8 over 2.0 metres from the unconformity at a depth of approximately 400 metres. Subsequent to the quarter, a further hole, 600 metres along strike, returned similar intensely altered unconformity related mineralization with a grade of 0.248 % eU 3 O 8 over 2.8 metres.

Denisons exploration spending in 2008 in the Athabasca Basin is expected to total $15,300,000.

Southwest United States

Mongolia

In Mongolia, fieldwork is well underway and on schedule on six projects. Fifteen large diameter core holes were drilled at the main part of the Haraat deposit to provide samples for metallurgical testwork which is underway and has shown promising recoveries based on results to date. Exploration and development drilling commenced on the Hairhan, Gurvan Saihan, and Ulziit depressions and production was on target, with almost 34,000 metres of the 85,000 metres completed by the end of the quarter. Most of the work completed at Hairhan was in support of resource definition in advance of a NI 43-101 report, expected to be completed in early fall. Hydrological drilling for baseline monitoring and test wells at the Hairhan deposit, in support of the planned ISR pilot plant next year, was also initiated. The Company expects to spend $11.5 million in Mongolia in 2008.

Zambia

Subsequent to the quarter, a drill hole testing a new area near the Mutanga deposit returned an intersection of 69.1 metres of 436 ppm eU 3 O 8 . This drill hole represents one of the best intercepts from any hole on the Mutanga project. A third drill will also begin drilling exploration targets upon the completion of a hydrological drill program which is being done as part of the overall project work.

1 The grades reported herein are equivalent U 3 O 8 grades based on down hole radiometric probing at a cut-off grade of 0.05% eU ; geochemical corroborative assay results have not been completed at this time. All intersections and geological interpretations are based on diamond drill core only and mineralized intervals may not represent true thickness. For a description of the quality assurance program and quality control measures applied by both ARC and Denison during the above described work, please see Denisons Annual Information Form filed under the Companys profile on March 28, 2008 on the SEDAR website at www.sedar.com.

The technical information contained in this MD&A relating to the described exploration activities is reported and verified by William C. Kerr, Denisons Vice-President, Exploration, who is a qualified person as defined in National Instrument 43-101.

Metallurgical testwork on the large sample delivered to Perth in the previous quarter is underway. The Mutanga programs will cost about $23,100,000 in 2008.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $7,388,000 at June 30, 2008 compared with $19,680,000 at December 31, 2007. The decrease of $12,292,000 was due primarily to expenditures of $64,964,000 for property, plant and equipment and the purchase of long term investments totaling $13,413,000 financed by cash from operations of $1,670,000 and an increase in bank debt of $66,064,000.

Net cash from operating activities was $1,670,000 during the six month period ended June 30, 2008. Net cash from operating activities is comprised of net loss for the period, adjusted for non-cash items and for changes in working capital items. Significant changes in working capital items during the period include a decrease of $12,494,000 in trade and other receivables and an increase of $15,260,000 in inventories. The decrease in trade and other receivables is primarily the result of the level of uranium sales in the period. The increase in inventories consists primarily of the increase in ore in stockpile.

Net cash used in investing activities was $77,322,000 consisting primarily of expenditures on property, plant and equipment of $64,964,000 and the purchase of long term investments of $13,413,000. The long term investment was primarily the purchase of shares and warrants in Uranerz Energy Corp.

Net cash from financing activities consisted of $66,064,000 from bank debt and $1,312,000 from the exercise of stock options and warrants.

In total, these sources and uses of cash resulted in a net cash outflow of $12,292,000 during the six month period. In July 2008, the Company put in place a $125,000,000 revolving term credit facility. The facility is repayable in full on June 30, 2011. The facility requires mandatory prepayment of outstanding credit in excess of $80,000,000 should the Companys uranium production in 2008 fall below 1,700,000 pounds.

The borrower under the facility is Denison Mines Inc. (DMI) and Denison Mines Corp. (DMC) has provided an unlimited full recourse guarantee and a pledge of all of the shares of DMI. DMI has provided a first-priority security interest in all present and future personal property and an assignment of its rights and interests under all material agreements relative to the McClean Lake and Midwest projects.

The Company is required to maintain the following financial covenants on a consolidated basis:

| | Minimum tangible net worth of $450,000,000 plus 50% of positive quarterly net income and
50% of net proceeds of all equity issues after December 31, 2007; |
| --- | --- |
| | Maximum ratio of total net debt to earnings before interest, taxes, depreciation and
amortization (EBITDA) of 3.5 to 1.0 for each fiscal quarter starting with the fiscal
quarter ending December 31, 2008 and including the fiscal quarter September 30, 2009 and
3.0 to 1.0 for each fiscal quarter thereafter; |
| | Minimum interest coverage ratio of 3.0 to 1.0 for each fiscal quarter starting with the
fiscal quarter ending December 31, 2008; and |
| | Minimum current ratio of 1.1 to 1.0. |

Interest payable under the facility is bankers acceptance rate or London Interbank Offered Rate (Libor) plus a margin or prime rate plus a margin. The margin used is between 0 and 200 basis points depending on the credit instrument used and the magnitude of the net total debt to EBITDA ratio (the ratio). The facility is subject to a standby fee of 40 to 55 basis points depending upon the ratio. A standby fee of 55 basis points applies in all circumstances where the amounts drawn under the facility are less than $62,500,000.

MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

During the second quarter of 2008, the Company substantially completed the implementation of the Great Plains financial system to support reporting of financial results. This system includes integrated financial modules for accounts payable, accounts receivable, fixed assets and inventory functions. Some work to complete the implementation will continue into Q3 2008. Management believes that the implementation of the Great Plains financial modules will improve the Companys internal control over financial reporting.

DENISON MINES CORP. Managements Discussion and Analysis Six Months Ended June 30, 2008 (Expressed in U.S. Dollars, Unless Otherwise Noted)

Other than the changes mentioned above, no other changes in the Companys internal control over financial reporting occurred during the second quarter of 2008 that have materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.

CHANGES IN ACCOUNTING POLICIES

The Company adopted the following new accounting standards issued by the Canadian Institute of Chartered Accountants (CICA) Handbook effective January 1, 2008:

| a) | CICA Handbook Section 3031 Inventories which provides guidance on the determination
of cost and its subsequent recognition as an expense, including any write-down to net
realizable value. It also provides guidance on the cost formulas that are used to assign costs to inventories. There was no impact to the Companys
financial results from adopting this standard. |
| --- | --- |
| b) | CICA Handbook Section 3862 Financial Instruments Disclosures and Section 3863
Financial Instruments Presentation which requires disclosures in the financial
statements that will enable users to evaluate: the significance of financial instruments
for the companys financial positions and performance; the nature and extent of risks
arising from financial instruments to which the company is exposed during the period and at
the balance sheet date; and how the company manages those risks. |
| c) | CICA Handbook Section 1535 Capital Disclosures which requires the disclosure of both
qualitative and quantitative information that enable users to evaluate the companys
objectives, policies and processes for managing capital. |

ACCOUNTING STANDARD ISSUED BUT NOT YET ADOPTED

The CICA has issued the following accounting standards which are effective for the Companys fiscal years beginning on or after January 1, 2009.

a) CICA Handbook Section 3064 Goodwill and intangible assets which establishes revised standards for recognition, measurement, presentation and disclosure of goodwill and intangible assets. Concurrent with the introduction of this standard, the CICA withdrew EIC 27 Revenues and expenses during the pre-operating period. As a result of the withdrawal of EIC 27, the Company will no longer be able to defer costs and revenues incurred prior to commercial production at new mine operations.

The Company has not yet determined the impact of adopting the above accounting standards.

RISK FACTORS

There are a number of factors that could negatively affect Denisons business and the value of Denisons securities, including the factors listed in the Companys Annual Information Form and in the Companys annual MD&A dated March 18, 2008 available at www.sedar.com and Form 40-F available at www.sec.gov . The information pertains to the outlook and conditions currently known to Denison that could have a material impact on the financial condition of Denison. This information, by its nature, is not all-inclusive. It is not a guarantee that other factors will not affect Denison in the future.

DENISON MINES CORP. Notes to the Consolidated Financial Statements (Unaudited Expressed in U.S. dollars, unless otherwise noted)

1.	NATURE OF OPERATIONS
	Denison Mines Corp. (DMC) is incorporated under the Business Corporations Act (Ontario)
(OBCA). Denison Mines Corp. and its subsidiary companies and joint ventures (collectively,
the Company) are engaged in uranium mining and related activities, including acquisition,
exploration and development of uranium bearing properties, extraction, processing, selling and
reclamation. The environmental services division of the Company provides mine decommissioning
and decommissioned site monitoring services for third parties.
	The Company has a 100% interest in the White Mesa mill located in Utah, United States and a
22.5% interest in the McClean Lake mill located in the Athabasca Basin of Saskatchewan, Canada.
The Company has interests in a number of nearby mines at both locations, as well as interests in
development and exploration projects located in Canada, the United States, Mongolia and Zambia,
some of which are operated through joint ventures. Uranium, the Companys primary product, is
produced in the form of uranium oxide concentrates (U 3 O 8 ) and sold to
various customers around the world for further processing. Vanadium, a co-product of some of
the Companys mines is also produced. The Company is also in the business of recycling uranium
bearing waste materials, referred to as alternate feed materials.
	Denison Mines Inc. (DMI), a subsidiary of the Company is the manager of Uranium Participation
Corporation (UPC), a publicly-listed investment holding company formed to invest substantially
all of its assets in U 3 O 8 and uranium hexafluoride (UF 6 ).
The Company has no ownership interest in UPC but receives various fees for management services
and commissions from the purchase and sale of U 3 O 8 and UF 6 by
UPC.
2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	These unaudited consolidated financial statements have been prepared by management in U.S.
dollars, unless otherwise stated, in accordance with generally accepted accounting principles in
Canada (Canadian GAAP) for interim financial statements.
	Certain information and note disclosures normally included in the annual consolidated financial
statements prepared in accordance with Canadian GAAP have been condensed or excluded. As a
result, these unaudited interim consolidated financial statements do not contain all disclosures
required for annual financial statements and should be read in conjunction with the Companys
audited consolidated financial statements and notes thereto for the year ended December 31,
2007.
	All material adjustments which, in the opinion of management, are necessary for fair
presentation of the results of the interim periods have been reflected in these financial
statements. The results of operations for the six months ended June 30, 2008 are not
necessarily indicative of the results to be expected for the full year.
	These unaudited interim consolidated financial statements are prepared following accounting
policies consistent with the Companys audited consolidated financial statements and notes
thereto for the year ended December 31, 2007, except for the changes noted under the New
Accounting Standards Adopted section below.

16. STOCK OPTIONS

The Companys stock-based compensation plan (the Plan) provides for the granting of stock options up to 10% of the issued and outstanding common shares at the time of grant, subject to a maximum of 20 million common shares. As at June 30, 2008, an aggregate of 12,501,500 options have been granted (less cancellations) since the Plans inception in 1997.

Under the Plan, all stock options are granted at the discretion of the Companys board of directors, including any vesting provisions if applicable. The term of any stock option granted may not exceed ten years and the exercise price may not be lower than the closing price of the Companys shares on the last trading day immediately preceding the date of grant. In general, the term of stock options granted under the Plan ranges from three to five years and vesting occurs over a three year period.

Outstanding options expire between September 2008 and October 2016.

The fair value of each option granted is estimated on the date of grant using the Black-Scholes option pricing model. The following table outlines the range of assumptions used in the model for the period:

	Six Months
	Ended
	June 30, 2008
Risk-free interest rate	2.86% - 3.29 %
Expected stock price volatility	52.2% - 55.4 %
Expected life	2.1 3.5 years
Expected dividend yield
Fair value per share under options granted	CDN$2.16 - CDN$4.49

Stock-based compensation has been recognized in the consolidated statement of operations as follows:

	Three Months Ended — June 30	June 30	Six Months Ended — June 30	June 30

General and administrative	561	281	1,118	575
	$ 619	$ 342	$ 1,232	$ 688

The fair values of stock options with vesting provisions are amortized on a straight-line basis as stock-based compensation expense over the applicable vesting periods. At June 30, 2008, the Company had an additional $6,329,000 in stock-based compensation expense to be recognized periodically to February 2011.

	Major Customers
	The Companys business is such that, at any given time, it sells its uranium and vanadium
concentrates to and enters into process milling arrangements and other services with a
relatively small number of customers. In the six months ended June 30, 2008, two customers
accounted for approximately 66% of total revenues.
20.	RELATED PARTY TRANSACTIONS
	Uranium Participation Corporation
	The Company is a party to a management services agreement with UPC. Under the terms of the
agreement, the Company will receive the following fees from UPC: a) a commission of 1.5% of the
gross value of any purchases or sales of U 3 O 8 and UF 6 completed
at the request of the Board of Directors of UPC; b) a minimum annual management fee of
CDN$400,000 (plus reasonable out-of-pocket expenses) plus an additional fee of 0.3% per annum
based upon UPCs net asset value between CDN$100,000,000 and CDN$200,000,000 and 0.2% per annum
based upon UPCs net asset value in excess of CDN$200,000,000; c) a fee of CDN$200,000 upon the
completion of each equity financing where proceeds to UPC exceed CDN$20,000,000; d) a fee of
CDN$200,000 for each transaction or arrangement (other than the purchase or sale of
U 3 O 8 and UF 6 ) of business where the gross value of such
transaction exceeds CDN$20,000,000 (an initiative); and e) an annual fee up to a maximum of
CDN$200,000, at the discretion of the Board of Directors of UPC, for on-going maintenance or
work associated with an initiative.
	In accordance with the management services agreement, all uranium investments owned by UPC are
held in accounts with conversion facilities in the name of Denison Mines Inc. as manager for and
on behalf of UPC.
	From time to time, the Company has also provided temporary revolving credit facilities to UPC
which generate interest and standby fee income. No such facilities were in place for the six
month period ending June 30, 2008.

	$ 1,347	$ 11,905	$ 2,186	$ 12,563

(a) Credit Risk

The Companys credit risk is related to trade receivables in the ordinary course of business. The Company sells uranium exclusively to large organizations with strong credit ratings and the balance of trade receivables owed to the Company in the ordinary course of business can be significant. In the event that these large organizations are unable to satisfy their financial obligations, the Company may incur additional expenses as a result of such credit exposure.

(b) Liquidity Risk

The Company has in place a planning and budgeting process to help determine the funds required to support the Companys normal operating requirements on an ongoing basis and its development plans. The Company believes that there is sufficient committed capital to meet its short-term business requirements, taking into account its anticipated cash flows from operations and its holdings of cash and cash equivalents. The Company has in place a three year term revolving credit facility in the amount of US$125,000,000 to meet its cash flow needs (see note 11).

DENISON MINES CORP. Notes to the Consolidated Financial Statements (Unaudited Expressed in U.S. dollars, unless otherwise noted)

Financial instruments that impact the Companys operations or other comprehensive income due to currency fluctuations include: non United States dollar denominated cash and cash equivalents, accounts receivable, accounts payable, long-term investments and bank debt.

The sensitivity of the Companys operations and other comprehensive income due to changes in the exchange rate between the Canadian dollar and its Zambian kwacha functional currencies and its United States dollar reporting currency as at June 30, 2008 is summarized below:

	Change in		Change in — Comprehensive
(in thousands)	Net Income (1)		Net Income (1)
Canadian dollar
10% increase in value	$ 166		$ 59,965
10% decrease in value	$ (166	)	$ (59,965	)
Zambian kwacha
10% increase in value	$ (8,124	)	$ (8,124	)
10% decrease in value	$ 8,124		$ 8,124

(1) In the above table, positive (negative) values represent increases (decreases) in net income and comprehensive net income respectively.

(d) Interest Rate Risk

The Company is exposed to interest rate risk on its outstanding borrowings and short-term investments. Presently, all of the Companys outstanding borrowings are at floating interest rates. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk. The weighted average interest rate paid by the Company during the six months ending June 30, 2008 on its outstanding borrowings was 4.82%.

An increase in interest rates of 100 basis points (1 percent) would have increased the amount of interest expense recorded during the six months by approximately $105,000.

(e) Price Risk

The Company is exposed to price risk on the commodities which it produces and sells. The Company is exposed to equity price risk as a result of holding long-term investments in other exploration and mining companies. The Company does not actively trade these investments.

The sensitivity analyses below have been determined based on the exposure to commodity price risk and equity price risk at June 30, 2008:

	Change in		Change in — Comprehensive
(in thousands)	Net Income (1)		Net Income (1)
Commodity price risk
10% increase in uranium prices (2)	$ 1,992		$ 1,992

Equity price risk
10% increase in equity prices	$		$ 6,643
10% decrease in equity prices	$		$ (6,643	)

| (1) | In the above table, positive (negative) values represent increases (decreases) in net
income and comprehensive net income respectively. |
| --- | --- |
| (2) | The Company is exposed to fluctuations in both the spot price and long-term price of
uranium as a result of the various pricing formulas in the uranium contracts. The above
sensitivity analysis includes 10% adjustments to both of these prices. |

The fair value of financial instruments which trade in active markets (such as available-for-sale securities) is based on quoted market prices at the balance sheet date. The quoted marked price used to fair value financial assets held by the Company is the current bid price.

22.	INCOME TAXES
	For the six months ended June 30, 2008, the Company has provided for current tax recovery of
$1,590,000 and for future tax expense of $8,547,000.
	In March, 2008, the Zambian government enacted legislation which increased the income tax rate
for mining companies from 25% to 30%. Accordingly, the Company recorded a future tax expense of
$10,740,000 in the period to adjust the future income tax liability associated with its Zambian
assets. This amount has been partially offset by the recognition of previously unrecognized
Canadian tax assets of $3,700,000.
23.	COMMITMENTS AND CONTINGENCIES
	General Legal Matters
	The Company is involved, from time to time, in various other legal actions and claims in the
ordinary course of business. In the opinion of management, the aggregate amount of any
potential liability is not expected to have a material adverse effect on the Companys financial
position or results.
	Third Party Indemnities
	The Company has agreed to indemnify Calfrac Well Services against any future liabilities it may
incur related to the assets or liabilities transferred to the Company on March 8, 2004.

MINERAL PROPERTY EXPLORATION

A majority of the exploration expenditures during the period were spent in the Athabasca Basin region of northern Saskatchewan. Denison is engaged in uranium exploration on advanced projects in this region of Canada as part of the ARC operated McClean and Midwest joint ventures and is also participating in a total of 34 other exploration projects concentrated in the prospective eastern margin of the Athabasca Basin. Denisons share of exploration spending on its Canadian properties totaled $2,758,000 of which $2,546,000 was expensed in the statement of operations for the three months ended June 30, 2008. For the three months ended June 30, 2007, exploration spending totaled $3,279,000 of which $3,059,000 was expensed. For the six months ended June 30, 2008, Denisons share of exploration spending on its Canadian properties totaled $9,168,000 of which $8,474,000 was expensed compared with spending of $8,433,000 of which $7,894,000 was expensed in the six months ended June 30, 2007.

Exploration expenditures of $1,090,000 for the three months ended June 30, 2008 ($319,000 for the three months ended June 30, 2007) and of $1,421,000 for the six months ended June 30, 2008 ($461,000 for the six month period in 2007) were incurred in Mongolia on the Companys joint venture and 100% owned properties. The Company has a 70% interest in the Gurvan Saihan Joint Venture (GSJV) in Mongolia. The other parties to the joint venture are the Mongolian government as to 15% and Geologorazvedka, a Russian government entity, as to 15%. Additional expenditures for development of the GSJVs Hairhan uranium deposits have also been incurred.

Exploration 1

Athabasca Basin

On the 60% owned Wheeler River property, the first hole of the summer program, WR-249, discovered a new zone of unconformity mineralization in an area not previously tested, and returned very intense sandstone alteration surrounding an assay of 0.263% eU 3 O 8 over 2.0 metres from the unconformity at a depth of approximately 400 metres. Subsequent to the quarter, a further hole, 600 metres along strike, returned similar intensely altered unconformity related mineralization with a grade of 0.248 % eU 3 O 8 over 2.8 metres.

Denisons exploration spending in 2008 in the Athabasca Basin is expected to total $15,300,000.

Southwest United States

Mongolia

In Mongolia, fieldwork is well underway and on schedule on six projects. Fifteen large diameter core holes were drilled at the main part of the Haraat deposit to provide samples for metallurgical testwork which is underway and has shown promising recoveries based on results to date. Exploration and development drilling commenced on the Hairhan, Gurvan Saihan, and Ulziit depressions and production was on target, with almost 34,000 metres of the 85,000 metres completed by the end of the quarter. Most of the work completed at Hairhan was in support of resource definition in advance of a NI 43-101 report, expected to be completed in early fall. Hydrological drilling for baseline monitoring and test wells at the Hairhan deposit, in support of the planned ISR pilot plant next year, was also initiated. The Company expects to spend $11.5 million in Mongolia in 2008.

Zambia

1 The grades reported herein are equivalent U 3 O 8 grades based on down hole radiometric probing at a cut-off grade of 0.05% eU ; geochemical corroborative assay results have not been completed at this time. All intersections and geological interpretations are based on diamond drill core only and mineralized intervals may not represent true thickness.

| | During the six months ended June 30, 2008, the Company incurred management and administrative
service fees of $99,000 (June 2007: $95,000) with a company owned by the Chairman of the
Company which provides corporate development, office premises, secretarial and other services in
Vancouver at a rate of CDN$15,000 per month plus expenses. At June 30, 2008, $44,000 was due to

| 21. | CAPITAL MANAGEMENT AND FINANCIAL INSTRUMENTS |
| | Capital Management |
| | The Companys capital includes debt and shareholders equity. The Companys primary objective
with respect to its capital management is to ensure that it has sufficient capital to maintain
its ongoing operations, to provide returns for shareholders and benefits for other stakeholders
and to pursue growth opportunities. As at June 30, 2008, the Company is subject to externally
imposed capital requirements related to its revolving credit facility (see note 11). |
| | Fair Values of Financial Instruments |
| | The Company examines the various financial instrument risks to which it is exposed and assesses
the impact and likelihood of those risks. These risks may include credit risk, liquidity risk,
currency risk, interest rate risk and price risk. |
| | (a) Credit Risk |
| | The Companys credit risk is related to trade receivables in the ordinary course of business.
The Company sells uranium exclusively to large organizations with strong credit ratings and the
balance of trade receivables owed to the Company in the ordinary course of business can be
significant. In the event that these large organizations are unable to satisfy their financial
obligations, the Company may incur additional expenses as a result of such credit exposure. |
| | (b) Liquidity Risk |
| | The Company has in place a planning and budgeting process to help determine the funds required
to support the Companys normal operating requirements on an ongoing basis and its development
plans. The Company believes that there is sufficient committed capital to meet its short-term
business requirements, taking into account its anticipated cash flows from operations and its
holdings of cash and cash equivalents. The Company has in place a three year term revolving
credit facility in the amount of US$125,000,000 to meet its cash flow needs (see note 11). |

	(f) Fair Value Estimation
	The fair value of financial instruments which trade in active markets (such as
available-for-sale securities) is based on quoted market prices at the balance sheet date. The
quoted marked price used to fair value financial assets held by the Company is the current bid
price.
22.	INCOME TAXES
	For the six months ended June 30, 2008, the Company has provided for current tax recovery of
$1,590,000 and for future tax expense of $8,547,000.
	In March, 2008, the Zambian government enacted legislation which increased the income tax rate
for mining companies from 25% to 30%. Accordingly, the Company recorded a future tax expense of
$10,740,000 in the period to adjust the future income tax liability associated with its Zambian
assets. This amount has been partially offset by the recognition of previously unrecognized
Canadian tax assets of $3,700,000.
23.	COMMITMENTS AND CONTINGENCIES
	General Legal Matters
	The Company is involved, from time to time, in various other legal actions and claims in the
ordinary course of business. In the opinion of management, the aggregate amount of any
potential liability is not expected to have a material adverse effect on the Companys financial
position or results.
	Third Party Indemnities
	The Company has agreed to indemnify Calfrac Well Services against any future liabilities it may
incur related to the assets or liabilities transferred to the Company on March 8, 2004.
