Revenue

During the second quarter the Company sold 113,000 pounds of vanadium blackflake (“V₂O₅”) at an average price of $6.89 per pound and 238,000 pounds of ferrovanadium (“FeV”) at an average price of $14.87 per pound. In the second quarter of 2009, the Company sold 506,000 pounds of V₂O₅ at an average price of $3.67 per pound and 18,000 pounds FeV at an average price of $8.75 per pound. Total vanadium sales revenue for the second quarter 2010 was $4,327,000 compared to $2,018,000 in the second quarter of 2009.

Revenue from Denison’s environmental services division was $3,471,000 for the three months ended June 30, 2010 compared to $2,843,000 for the three months ended June 30, 2009. The increase in revenue is due to the increased activity related to the Company’s contract with the Yukon government for site maintenance and water treatment for the FARO mine site in Yukon on which the Company commenced work in March 2009. Revenue from the management contract with Uranium Participation Corporation was $378,000 for the three months ended June 30, 2010 compared to $1,247,000 in the same period in 2009. The reduction is due to transaction fees earned in the second quarter of 2009.

Other Income

During the quarter the Company agreed to terminate one of its uranium sales contracts in exchange for a termination fee of $11,000,000. The fee is payable in two installments of $6,000,000 received in June 2010 and $5,000,000 payable in March 2011.

Operating Expenses

Canadian Operations

The McClean Lake Joint Venture produced 748,000 pounds U₃O₈ for the three months ended June 30, 2010 compared with 1,024,000 pounds U₃O₈ for the three months ended June 30, 2009. Denison’s 22.5% share of production totaled 168,000 pounds compared to 230,000 pounds for the corresponding 2009 period.

Production costs⁽¹⁾ were $29.89 per pound U₃O₈ for the three months ended June 30, 2010. For the comparable period in 2009, the production costs were $23.89 per pound U₃O₈.

Inventory available for sale from Canadian production was 336,000 pounds U₃O₈ at June 30, 2010. The McClean Lake joint venture completed processing of ore in June, 2010. The circuits are being cleaned out and the mill will be put on care and maintenance in August.

U.S. Operations

At the White Mesa mill, processing of conventional ore resumed in March, 2010 while processing alternate feed material continued. The Company produced 250,000 pounds U₃O₈and 911,000 pounds V₂O₅from conventional ore processing. Production from alternate feed material in the three months ended June 30, 2010 was 110,000 pounds U₃O₈.

- 2 -

At June 30, 2010 a total of 150,000 tons of conventional ore was stockpiled at the mill containing approximately 661,000 pounds U₃O₈ and 3,049,000 pounds V₂O₅. The Company also has approximately 465,000 pounds U₃O₈ contained in the alternate feed material stockpiled at the mill at June 30, 2010.

Production costs ⁽¹⁾ for the three months ended June 30, 2010 were $34.39 per pound U₃O₈and $38.83 per pound U₃O₈ for the six months ended June 30, 2010_.

Inventory available for sale from U.S. production was 300,000 pounds U₃O₈, 757,000 pounds V₂O₅and 45,000 pounds FeV at June 30, 2010.


⁽¹⁾		Production costs include the costs of mining the ore fed to the mill in the period plus the costs of milling the ore less a credit for vanadium produced in the period and excluding depreciation and amortization, which is a non-GAAP measure.

Other

Operating costs for the second quarter include a recovery of $4,693,000 relating to the net realizable value of the Company’s uranium and vanadium inventory. Operating expenses also include costs relating to Denison’s environmental services division amounting to $2,974,000 in the three month period ended June 30, 2010 and $2,551,000 in the comparable period in 2009.

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, 2010 exploration expenditures totaled $1,766,000 compared to $2,502,000 for the three months ended June 30, 2009.

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 as part of the McClean and Midwest joint ventures operated by AREVA Resources Canada Inc. (“ARC”), as well as on 29 other exploration projects including the Company’s 60% owned Wheeler River project. Denison’s share of exploration expense on its Canadian properties totaled $1,678,000 for the three months ended June 30, 2010.

The 2010 summer drill program at the Phoenix uranium deposit on the 60% owned Wheeler River property has discovered two new mineralized zones on the north east and south west edges of the presently defined Phoenix trend. Both of these zones are open along strike and the results confirm Denison’s belief that the Phoenix discovery is a major deposit with now four discrete zones of mineralization over a length of 1,300 metres. The 45 hole summer drill program is continuing. An NI 43-101 compliant resource report is currently in preparation and scheduled to be completed in the fourth quarter of 2010.

Liquidity

The Company had cash and cash equivalents of $21,992,000 at June 30, 2010 and trade and other receivables of $13,110,000. Portfolio investments had a market value of $5,720,000. The Company has in place a revolving credit facility of $60,000,000. The facility expires on June 30, 2011. Bank indebtedness under the facility at June 30, 2010 was nil; however, $9,110,000 of the line is used as collateral for certain letters of credit.

Outlook for 2010

Mining and Production

•

2010 uranium production is expected to total 1.6 million pounds U₃O₈ and vanadium production is estimated to total 2.8 million pounds V₂O₅.

•

Uranium sales are projected at 1.8 million pounds U₃O₈, and vanadium sales are expected to be at 3.2 million pounds V₂O₅ in 2010. The Company expects to achieve an average realized uranium price of $45.62 per pound, based on an assumed long term price of $59.00 per pound and a spot price of $42.00 per pound U₃O₈ for the remainder of the year. Mining revenue is forecast to be $104.7 million of which $20.8 million is expected to be vanadium sales based on an assumed price of $6.50 per pound V₂O₅ for the remainder of the year. The average uranium price and mining revenue is expected to be lower than previously forecast due to the termination of a long term sales contract. The lower revenue will be offset by the termination fee included in other income.

•

The cost of production in Canada is expected to average $31.52 per pound U₃O₈. The cost of production in the U.S. is expected to be $35.52 per pound U₃O₈ net of vanadium credits. The cost of production is estimated using the proposed costs of mining the ore fed to the mill in the period plus the costs of milling less a credit for vanadium produced in the period excluding amortization and depreciation.

- 3 -

•

Capital expenditures for 2010 at the Company’s operations are estimated at $18.4 million.

•

In 2010 Denison will participate in exploration programs on properties in Canada and the United States. Denison’s share of spending on these programs is expected to be approximately $5.9 million. This is higher than previously forecast due to an increase in the summer drill program at Wheeler River.

•

Development spending will total $8.7 million in 2010 of which $5.0 million will be incurred on the Zambian and Mongolian projects. The remainder will be spent on Denison’s U.S. and ARC operated Canadian projects and on evaluation of acquisitions.

Inventory from Canadian production was 336,000 pounds U₃O₈ at June 30, 2010.

On June 30, 2009, the Canadian Nuclear Safety Commission (“CNSC”) renewed the operating licence for the McClean Lake operation for a period of eight years to June 30, 2017. The Athabasca Regional Government (the “ARG”), which is comprised of three First Nations and four provincial communities from the Athabasca Basin, launched a judicial review of CNSC’s decision to grant the McClean Lake operating licence. The ARG is challenging the legality of the licence renewal on the basis of issues related to the Federal and Provincial Governments’ duty to consult with Aboriginal people. The initial hearing on this matter was held on June 8, 2010 and the judge reserved his decision stating that the decision will take at least a month. The operations should not be affected by the legal proceedings; however, an adverse decision by the court could have an impact on the timing of the Company’s future production.

At the White Mesa mill processing of conventional ore resumed in March 2010 in addition to the ongoing processing of alternate feed material. Production from conventional ore during the quarter totaled 250,000 pounds U₃O₈and 911,000 pounds V₂O₅. Production from alternate feed material in the three months ended June 30, 2010 was 110,000 pounds U₃O₈ and 218,000 pounds for the six months ended June 30, 2010.

At June 30, 2010, a total of 150,000 tons of conventional ore was stockpiled at the mill containing approximately 661,000 pounds U₃O₈ and 3,049,000 pounds V₂O₅. The Company also had approximately 465,000 pounds U₃O₈ contained in the alternate feed material stockpiled at the mill at June 30, 2010.

Production costs⁽¹⁾ for the three months ended June 30, 2010 were $34.39 per pound U₃O₈ and for the six months ended June 30, 2010 were $38.83. Production costs were $71.50 per pound U₃O₈ in the six months ended June 30, 2009.

Inventory available for sale from U.S. production was 300,000 pounds U₃O₈, 757,000 pounds V₂O₅ and 45,000 pounds FeV at June 30, 2010.

On November 16, 2009, as amended on February 1, 2010, the Center for Biological Diversity, Grand Canyon Trust, Sierra Club, Kaibab Band of Paiute Indians and Havasupai Tribe (the “Plaintiffs”) filed a lawsuit against the U.S. Secretary of the Interior and the U.S. Bureau of Land Management (“BLM”) (together, the “Defendants”) seeking an order declaring that the Defendants have violated environmental laws in relation to the Company’s Arizona 1 mine, by not requiring a new Plan of Operations in connection with the start of mining activities. The Plaintiffs are also claiming that, if a new Plan of Operations is not required, the Defendants failed to conduct a review of potential environmental impacts from the mine since the existing Plan of Operations for the mine was approved by BLM in 1988. The Plaintiffs further claim that all required permits have not been obtained for the mine under the Clean Air Act, and that, as a result, BLM failed to take all actions necessary to prevent unnecessary degradation of the public lands. The Plaintiffs are seeking an order declaring that the Defendants have violated these environmental laws in relation to the Arizona 1 mine, and an injunction directing operations to cease and stopping the Defendants from authorizing or allowing any further mining or exploration operations at the Arizona 1 mine until BLM complies with all applicable laws. On February 8, 2010 the Defendants filed an Answer to the Plaintiffs’ complaint denying the foregoing allegations. Denison has been added as an intervener in this lawsuit, and believes that each of these allegations is without legal merit; is not supported by the administrative record; and should be dismissed. On April 19, 2010, Plaintiffs filed a motion for a preliminary injunction to shut down operations at the mine pending a decision on the merits of the case. A hearing on the motion for an injunction was held on June 11, 2010 and on June 17, 2010 the judge denied the Plaintiffs’ request for preliminary injunctive relief. On July 12, 2010, the Plaintiffs appealed the ruling on the preliminary injunction to the Ninth Circuit Court of Appeals, and on July 14, 2010 filed another motion for preliminary injunction, pending appeal. The original case is ongoing. If the Plaintiffs are successful on the current motion for preliminary injunction, on the appeal or on the merits, the Company may be required to stop mining activities at the Arizona 1 mine pending resolution of this matter. Any required stoppage of mining, could have a significant adverse impact on the Company.

In August 2009, the Arizona Department of Environmental Quality (“ADEQ”) issued an air quality permit that authorized the restart and operation of the Arizona 1 mine. Despite this authorization by ADEQ and a previous authorization of construction and operation of the mine by the United States Environmental Protection Agency (“EPA”) in 1988, EPA has alleged that a new EPA approval is required at this time, notwithstanding the ADEQ permit. On May 3, 2010, EPA issued a Finding of Violation to Denison alleging non-compliance with the provisions of the Clean Air Act for not obtaining this second EPA approval and associated matters. EPA and Denison are currently negotiating a Consent Agreement and Final Order to settle this administrative action, under which Denison, after submitting the requested application, will agree to pay a stipulated penalty.

On July 29, 2010, Uranium Watch, Living Rivers and Center for Water Advocacy (the “Plaintiffs”) filed a lawsuit against the U.S. Forest Service (“USFS”) and the Forest Supervisor for the Manti-La Sal National Forest (together, the “Defendants”) seeking an order declaring that the Defendants have violated environmental laws in relation to the Company’s Pandora mine, by not requiring an Environmental Assessment or Environmental Impact Statement under the National Environmental Policy Act (“NEPA”) in connection with the USFS’ approval of Plans of Operation authorizing the Company to construct two vent holes and drill 16 uranium exploration holes at the mine. The Plaintiffs are seeking an order declaring that the Defendants have violated NEPA and vacating the USFS’ approval of the Plans of Operation for these two projects, and enjoining the USFS from allowing the projects to proceed pending full compliance with the law. The Plaintiffs have also filed a motion for a temporary restraining order and preliminary injunction against the commencement of the projects. Denison is currently evaluating these motions and is preparing a motion to be added as an intervenor in this lawsuit. If the Plaintiffs are successful on the motion for a temporary restraining order and preliminary injunction or on the merits, the Company’s ability to continue mining at the Pandora mine may be impacted, which could have a significant adverse impact on the Company.


⁽¹⁾		Production costs include the costs of mining the ore fed to the mill in the period plus the costs of milling less a credit for vanadium produced in the period and excluding depreciation and amortization, which is a non-GAAP measure.

Other

Operating costs for the three months and six months ended June 30, 2010 include a recovery of $4,693,000 and $7,445,000 respectively relating to the net realizable value of the Company’s uranium and vanadium inventory. For the three and six months ended June 30, 2009 operating costs include a recovery of $1,041,000 and an expense of $183,000 respectively. Operating costs also include expenses relating to the DES division amounting to $2,974,000 for the three months and $6,390,000 for the six months in 2010 compared to $2,551,000 and $3,905,000 respectively for the same periods in 2009.

Sales Royalties and Capital Taxes

Sales royalties on Canadian production and capital taxes totaled $1,053,000 and $1,287,000 for the three and six months ended June 30, 2010 compared with $335,000 and $688,000 for the same periods in 2009. 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 a Saskatchewan resource surcharge based on 3.0% of gross uranium sales. The Government of Saskatchewan 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. It is likely that Denison will pay tiered royalties in 2010. The Government of Saskatchewan, in conjunction with the uranium industry in Saskatchewan, is reviewing the current tiered royalty structure with a view to altering it to better align it with current and future industry economics.

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, 2010 exploration expenditures totaled $1,766,000 and $3,451,000 for the six months ended June 30, 2010 as compared to $2,502,000 for the three months ended June 30, 2009 and $4,579,000 for the six months ended June 30, 2009.

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 as part of the McClean and Midwest joint ventures operated by AREVA Resources Canada Inc. (“ARC”) as well as on 29 other exploration projects including the Company’s 60% owned Wheeler River project. Denison’s exploration expense on its Canadian properties totaled $1,678,000 for the three months ended June 30, 2010 and totaled $3,082,000 for the six months ended June 30, 2010. For the three months ended June 30, 2009, exploration expense totaled $1,576,000 and $3,432,000 for the six months ended June 30, 2009.

The 2010 summer program on the Phoenix uranium deposits on the 60% owned Wheeler River property has discovered two new mineralized zones on the north east and south west edges of the presently defined Phoenix trend. Both of these zones are open along strike and the results confirm Denison’s belief that Phoenix is a major discovery with now four discrete zones of mineralization over a length of 1,300 metres. The 45 hole summer drill program is continuing.

Exploration expenditures of $77,000 and $355,000 for the three months and six months ended June 30, 2010 compared to $913,000 for the three months and $1,130,000 for the six months ended June 30, 2009 were incurred in Mongolia on the Company’s joint venture 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%. Under the new Nuclear Energy Law, the Government of Mongolia could acquire a 34% to 51% interest at no cost to the Government. Denison is currently engaged with industry groups and trade representatives in Mongolia to determine how the new law could be applied in practice. Discussions are also underway between industry groups and the Mongolian Government in an effort to have the Government amend some of these provisions. At this time, it is not clear how the Mongolian Government will attempt to apply the new law to the GSJV, in light of the GSJV’s existing Mineral Agreement with Mongolian Government.

In Zambia, the Company was granted mining licences for its Mutanga and Dibwe properties in late March. These licenses are for a period of twenty-five years. Environmental baseline sampling is ongoing as well as environmental assessment studies for the access road and power line.

General and Administrative

General and administrative expenses totaled $2,769,000 for the three months and $6,024,000 for the six months ended June 30, 2010 compared with $3,531,000 for the three months and $7,853,000 for the six months ended June 30, 2009. The decrease is primarily due to decreased personnel expenses during the quarter. General and administrative expenses consist primarily of payroll and related expenses for personnel, contract and professional services and other overhead expenditures.

Stock Option Expense

Stock option expense totaled $443,000 and $838,000 for the three and six months ended June 30, 2010 compared to $1,538,000 and $1,705,000 for the three months and six months ended June 30, 2009.

Other Income and Expenses

Other income (expense) totaled $20,849,000 for the three months and $16,010,000 for the six months ended June 30, 2010 compared with $(7,186,000) for the three months and $(1,559,000) for the six months ended June 30, 2009. This includes foreign exchange gains or losses, interest income, investment disposal gains and other miscellaneous items. Foreign exchange gains totaled $3,690,000 for the six months ended June 30, 2010 compared to foreign exchange gains of $623,000 in the six months ended June 30, 2009. Other income also includes a uranium sales contract termination fee. During the quarter the Company agreed to terminate one of its sales contracts in exchange for a termination fee of $11,000,000. The fee is payable in two installments of $6,000,000 received in June, 2010 and $5,000,000 due in March, 2011.

Income Taxes

For the six months ended June 30, 2010 the Company has provided for a current tax recovery of $41,000 and a future tax recovery of $1,915,000. The future tax recovery includes $53,000 attributed to the recognition of previously unrecognized Canadian tax assets.

OUTLOOK FOR 2010

The Company is assuming a spot price of $42.00 per pound U₃O₈ and a long-term price of $59.00 per pound U₃O₈ for the remainder of 2010 and is assuming a price of $6.50 per pound V₂O₅. Foreign exchange rates is assumed at a rate of US$1.00 = CDN $1.00 for the balance of the year.

Mining Operations

Denison’s uranium production is expected to be unchanged at approximately 1.6 million pounds U₃O₈ in 2010. Vanadium production in 2010 is also expected to be unchanged at approximately 2.8 million pounds V₂O₅.

Uranium and vanadium sales volumes are expected to remain at 1.8 million pounds U₃O₈ and 3.2 million pounds V₂O₅. Based on the uranium prices noted above, the Company expects to achieve an average realized price of $45.62 per pound U₃O₈ sold. Mining revenue is now forecast to be approximately $104.7 million of which $20.8 million is expected to be vanadium sales. The average uranium price and mining revenue is expected to be lower than previously forecast due to the termination of a long-term sales contract. The lower revenue will be offset by the termination fee included in other income.

The cost of production in Canada is expected to average $31.52 per pound U₃O₈. The McClean Lake joint venture will shut down the McClean Lake mill in August 2010 until new feed sources are available. The stand-by costs to Denison are expected to be negligible as most of them will be paid for by the Cigar Lake joint venture. The cost of production in the U.S. is expected to be $35.52 per pound U₃O₈ net of vanadium credits. The cost of production is calculated using the costs of mining the ore fed to the mill in the period plus the costs of milling the ore less a credit for vanadium produced in the period and excludes amortization and depreciation.

Total operating capital expenditures are projected to be approximately $18.4 million.

Business Development

In 2010 Denison will participate in exploration programs on ten properties in Canada and the United States. Denison’s spending on these programs will be approximately $5.9 million of which $4.9 million will be spent in Canada. The most significant of these programs continues to be on the Phoenix deposits on the Wheeler River property in Saskatchewan. A 45 hole, 19,700 metre summer drill program is underway and will focus on further expanding the Phoenix deposit, and in particular drilling on the significant new zone of alteration to the northeast. An NI 43-101 compliant resource report is currently in preparation and is scheduled to be completed in the fourth quarter of 2010.

In the United States, work will be carried out on the Beaver and Pandora mine properties, once permits are received, at a cost of $1.0 million in an effort to outline new resources to extend the mine life of the existing operations on these properties.

Development spending will total $8.7 million in 2010 of which $5.0 million will be incurred on the Zambian and Mongolian projects and to develop a longer term strategy for these assets and their development. The remainder will be spent on Denison’s U.S. and ARC operated projects and on evaluation of acquisitions.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $21,992,000 at June 30, 2010 compared with $19,804,000 at December 31, 2009. The increase of $2,188,000 was due primarily to cash provided by operating activities of $14,395,000 and proceeds from sale of investments of $2,344,000 less expenditures of $15,148,000 on property, plant and equipment.

Net cash provided by operating activities of $14,395,000 during the six months ended June 30, 2010 is comprised of net income 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 an increase in accounts payable and accrued liabilities of $3,569,000, an increase of $7,001,000 in inventories and a decrease of $632,000 in trade and other receivables. The increase in inventories consists primarily of the increase in ore in stockpile.

Net cash used in investing activities was $11,577,000 consisting primarily of expenditures on property, plant and equipment of $15,148,000 less proceeds from the sale of investments of $2,344,000 and proceeds on sale of property plant and equipment of $1,530,000.

Net cash used in financing activities totaled $550,000 consisting of repayment of debt obligations.

In total, these sources and uses of cash resulted in a net cash inflow after the effect of foreign exchange of $2,188,000 during the period.

The Company has in place a $60,000,000 revolving term credit facility (“the credit facility”). The credit facility contains three financial covenants, one based on maintaining a certain level of tangible net worth, which must be greater than or equal to the sum of $665,000,000 plus an amount equal to (i) 50% of each equity issue after September 30, 2009; and (ii) 50% of positive net income in each fiscal quarter from September 30, 2009, the second requiring a minimum current ratio of 1.10 to 1 and the third requiring the Company to reduce the borrowing facility to $35,000,000 for a period of time each quarter before drawing further amounts. The credit facility expires on June 30, 2011. There is currently no debt outstanding under this credit facility; however $9,110,000 of the line is currently used as collateral for certain letters of credit.

The borrower under the credit facility is the Company’s subsidiary, DMI and the Company 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. In addition, each of the Company’s material U.S. subsidiaries has provided an unlimited full recourse guarantee secured by a pledge of all of its shares and a first-priority security interest in all of its present and future personal property. The credit facility is subject to a standby fee of 100 basis points.

OFF-BALANCE SHEET ARRANGEMENTS

The Company does not have any off-balance sheet arrangements.

TRANSACTIONS WITH RELATED PARTIES

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 uranium 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 UPC’s net asset value between CDN$100,000,000 and CDN$200,000,000 and 0.2% per annum based upon UPC’s 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 ofuranium) of a business where the gross value of such transaction exceeds CDN$20,000,000 (“an initiative”); 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; and f) a fee equal to 1.5% of the gross value of any uranium held by UPC prior to the completion of any acquisition of at least 90% of the common shares of UPC.

Korea Electric Power Corporation (“KEPCO”)

In June 2009, Denison completed definitive agreements with KEPCO. The agreements included a long-term offtake agreement which provides for the delivery to KEPCO of 20% of Denison’s annual U₃O₈ production (±10%) but not less than 350,000 pounds (±10%) per year from 2010 to 2015 inclusive. KEPCO also purchased 58,000,000 common shares of Denison representing approximately 17% of the issued and outstanding capital as at the June 2009 share purchase. Two representatives from KEPCO have been appointed to Denison’s board of directors.

OUTSTANDING SHARE DATA

At August 5, 2010, there were 339,720,415 common shares issued and outstanding, stock options to purchase a total of 7,004,473 common shares and warrants to purchase a total of 6,408,000 common shares, for a total of 353,132,888 common shares on a fully-diluted basis.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. Any system of internal control over financial reporting, no matter how well designed, has inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

There has not been any change in the Company’s internal control over financial reporting that occurred during the Company’s second quarter of 2010 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

CHANGES IN ACCOUNTING POLICIES

The Company has adopted the following new standards issued by the CICA:

CICA Handbook Section 1582 “Business Combinations”, Section 1601 “Consolidated Financial Statements” and Section 1602 “Non-Controlling Interests” which replace the former CICA 1581 “Business Combinations” and CICA 1600 “Consolidated Financial Statements” and establish a new section for accounting for a non-controlling interest in a subsidiary. These sections provide the Canadian equivalent to FASB Statements No. 141(R) “Business Combinations” and No. 160 “Non-Controlling Interests in Consolidated Financial Statements”. CICA 1582 is effective for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period after January 1, 2011. CICA 1601 and CICA 1602 apply to interim and annual consolidated financial statements relating to years beginning on or after January 1, 2011 although early adoption is permitted. CICA 1582, which replaces Handbook Section 1581, Business Combinations, establishes standards for the measurement of a business combination and the recognition and measurement of assets acquired and liabilities assumed. CICA 1601, which replaces Handbook Section 1600, carries forward the existing Canadian guidance on aspects of the preparation of consolidated financial statements subsequent to acquisition other than non-controlling interests. CICA 1602 establishes guidance for the treatment of non-controlling interests subsequent to acquisition through a business combination. The Company has early adopted all three sections effective January 1, 2010. There was no impact to the Company’s financial statements from adopting these standards.

CONVERSION TO INTERNATIONAL FINANCIAL REPORTING STANDARDS (IFRS)

The Company is in the process of converting its basis of accounting from Canadian GAAP to IFRS to be effective in the first quarter report 2011. The conversion date for IFRS reporting is January 1, 2011. The restatement for comparative purposes of amounts reported for the year ended December 31, 2010 will also be required.

The conversion to IFRS from Canadian GAAP is a significant undertaking. Management has established an IFRS project team that is staffed with both internal and external resources.

The implementation project plan consists of three phases:

•

Initial diagnostic phase

•

Impact analysis and design phase

•

Implementation phase

The initial diagnostic phase was completed in third quarter 2008. The impact analysis and design phase and the implementation phase were initiated in 2009 and efforts are continuing for 2010.

The impact analysis and design phase involves the selection of IFRS accounting policies by senior management and review by the audit committee; the quantification of impact of changes to the Company’s existing accounting policies on our opening IFRS balance sheet; and the development of draft IFRS financial statements.

The implementation phase involves the implementation of required changes to the Company’s information systems and procedures. It will culminate in the collection of financial information necessary to prepare IFRS financial statements and audit committee approval of financial statements.

During the second quarter, efforts were mainly focused on preparation of the IFRS opening balance sheet amounts for January 1, 2010. A preliminary calculation has been prepared and reviewed by management. The most significant adjustments resulted from differences in recognition of long-lived asset impairments primarily on mineral properties and tax related adjustments. The overall effect of the adjustments is expected to give rise to a decrease in the asset values on the IFRS balance sheet versus the Canadian GAAP balance sheet. Plans for the third quarter include finalization of opening balance sheet, development of first and second quarter 2010 IFRS financial statements and required note disclosures.

Management is using a combination of the current financial system application and some end-user computing tools to record the IFRS compliant financial information.

Other work that is underway includes analysis of additional financial statement and note disclosures, review of information system and internal control changes required, and additional training required for key personnel.

Potential Impact of IFRS Implementation on Denison

A description of the potential areas of impact of the IFRS implementation for Denison was outlined in the Company’s management discussion and analysis dated March 11, 2010 available at www.sedar.com or www.sec.gov.com. There have been no significant changes to the information that was provided in that disclosure. However, management continues to monitor new developments and/or changes to the IFRS standards for applicability to Denison.

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

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 and joint arrangements. Uranium, the Company’s primary product, is produced in the form of uranium oxide concentrates (“U₃O₈”) and sold to various customers around the world for further processing. Vanadium, a co-product of some of the Company’s U.S mines is also produced and is in the form of vanadium pentoxide (“V₂O₅”). The Company is also in the business of processing uranium bearing waste materials, referred to as “alternate feed materials”.

Denison Mines Inc. (“DMI”), a subsidiary of DMC, is the manager of Uranium Participation Corporation (“UPC”), a publicly-listed investment holding company formed to invest substantially all of its assets in U₃O₈ and uranium hexafluoride (“UF₆”). The Company has no ownership interest in UPC but receives various fees for management services and commissions from the purchase and sale of U₃O₈and UF₆ by UPC.

CAPITAL MANAGEMENT AND FINANCIAL INSTRUMENTS

Capital Management

The Company’s capital includes cash and shareholders’ equity. The Company’s 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.

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

Credit risk is the risk of loss due to a counterparty’s inability to meet its obligations under a financial instrument that will result in a financial loss to the Company. The carrying amount of financial assets represents the maximum credit exposure. The Company trades only with recognized, credit worthy third parties.

- 36 -

The maximum exposure to credit risk at the reporting date is as follows:


	At June 30
(in thousands)	2010

Cash and cash equivalents	$	21,992
Trade and other receivables		13,110
Investments		5,720
Restricted cash and investments		22,228

	$	63,050

(b)

Liquidity Risk

Liquidity risk is the risk that the Company will encounter difficulties in meeting obligations associated with its financial liabilities and other contractual obligations. The Company has in place a planning and budgeting process to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis. The Company ensures 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 maturities of the Company’s financial liabilities are as follows:


	Within 1		1 to 5
(in thousands)	Year		Years

Accounts payable and accrued liabilities	$	13,055	$	—
Debt obligations (Note 12)		294		220

	$	13,349	$	220

(c)

Currency Risk

Foreign exchange risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. The Company operates internationally and is exposed to foreign exchange risk arising from various currency exposures. Foreign exchange risk arises from assets and liabilities that are denominated in a currency that is not the functional currency for the relevant subsidiary company.

Currently, the Company does not have any foreign exchange hedge programs in place and manages its operational foreign exchange requirements through spot purchases in the foreign exchange markets.

The sensitivity of the Company’s 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, 2010 is summarized below:


				Change in
	Change in			Comprehensive
(in thousands)	Net Income ⁽¹⁾			Net Income ⁽¹⁾

Canadian dollar
10% increase in value	$	(15,516	)	$	23,830
10% decrease in value	$	15,516		$	(23,830	)
Zambian kwacha
10% increase in value	$	(2,804	)	$	(2,804	)
10% decrease in value	$	2,804		$	2,804


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

(d)

Interest Rate Risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company is exposed to interest rate risk on its outstanding borrowings and short-term investments. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk.

- 37 -

(e)

Price Risk

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 analysis below has been determined based on the exposure to equity price risk at June 30, 2010:


			Change in
	Change in		Comprehensive
(in thousands)	Net Income ⁽¹⁾		Net Income ⁽¹⁾

Equity price risk
10% increase in equity prices	$	—	$	572
10% decrease in equity prices	$	—	$	(572	)


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

(f)

Fair Value Estimation

The following table illustrates the classification of the Company’s financial assets within the fair value hierarchy as at June 30, 2010:


							Fair
(in thousands)	Level 1		Level 2		Level 3		Value

Financial assets at fair value:
Investments-available for sale securities ⁽¹⁾	$	5,720	$	—	$	—	$	5,720
Restricted investments ⁽²⁾		15,184		—		—		15,184


(1)		Classification designated as “available-for-sale”.

(2)		Classification designated as “held-to-trading”. See note 6 for amount of restricted investments within restricted cash and investments asset amount.

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 value financial assets held by the Company is the current bid price.

The fair values of cash and cash equivalents, trade and other receivables and accounts payable and accrued liabilities approximate their carrying values because of the short-term nature of these instruments.

The fair values of the Company’s restricted cash and investments approximate carrying values.

The fair values of the Company’s debt obligations approximate their carrying values.

23.

INCOME TAXES

For the six months ended June 30, 2010, the Company has recognized future tax recoveries of $1,915,000 The future tax recovery includes the recognition of previously unrecognized Canadian tax assets of $53,000.

24.

COMMITMENTS AND CONTINGENCIES

General Legal Matters
