DENISON MINES CORP.
Notes to the condensed interim consolidated financial statements for the three months and six months ended
June 30, 2011 and 2010
(Unaudited — Expressed in thousands of U.S. dollars)

1. NATURE OF OPERATIONS

Denison Mines Corp. (“DMC”) is incorporated under the Business Corporations Act (Ontario) (“OBCA”). The address of its registered head office is 595 Bay Street, Suite 402, Toronto, Ontario, Canada, M5J 2C2. 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 and selling of uranium. 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 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 U₃O₈ and UF₆ by UPC.

2. BASIS OF PRESENTATION AND ADOPTION OF IFRS

These unaudited consolidated financial statements have been prepared by management in U.S. dollars in accordance with Canadian generally accepted accounting principles as set out in the Handbook of the Canadian Institute of Chartered Accountants (“CICA Handbook”). In 2010, the CICA Handbook was revised to incorporate International Financial Reporting Standards (“IFRS”), and require publicly accountable enterprises to apply such standards effective for years beginning on January 1, 2011. Accordingly, the Company has commenced reporting on this basis in its 2011 interim consolidated financial statements. In these financial statements, the term “Canadian GAAP” refers to Canadian GAAP before the adoption of IFRS.

These interim consolidated financial statements have been prepared in accordance with IFRS applicable to the preparation of interim financial statements, including IAS 34 Interim Financial Reporting and IFRS 1 First-time Adoption of International Financial Reporting Standards. The interim consolidated statement of income (loss) for the six month period ending June 30, 2011 is not necessarily indicative of the operating results for the full year, primarily due to the timing of concentrate deliveries to customers. The accounting policies followed in these interim financial statements are the same as those applied in the Company’s interim financial statements for the period ended March 31, 2011. The Company has consistently applied the same accounting policies throughout all periods presented, as if these policies had always been in effect. Note 4 discloses the impact of the transition to IFRS on the Company’s reported financial position as at June 30, 2010 and comprehensive income for the three and six months ended June 30, 2010, including the nature and effect of significant changes in accounting policies from those used in the Company’s consolidated financial statements for the year ended December 31, 2010.

The accounting policies applied in these condensed interim consolidated financial statements are based on IFRS effective for the year ended December 31, 2011, as issued and outstanding as of August 4, 2011, the date the Board of Directors approved the statements. Any subsequent changes to IFRS that are given effect in the Company’s annual consolidated financial statements for the year ending December 31, 2011 could result in restatement of these interim consolidated financial statements, including the transition adjustments recognized on change-over to IFRS.

The condensed interim consolidated financial statements should be read in conjunction with the Company’s Canadian GAAP annual financial statements for the year ended December 31, 2010 and the Company’s interim financial statements for the quarter ended March 31, 2011 prepared in accordance with IFRS applicable to interim financial statements.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Significant Accounting Policies

The significant accounting policies followed in these interim financial statements are the same as those applied in the Company’s interim financial statements for the period ended March 31, 2011. In accounting for business combinations, the Company uses the following accounting policy:

(a) Business combinations

A business combination is defined as an acquisition of assets and liabilities that constitute a business. A business consists of inputs, including non-current assets, and processes, including operational processes, that when applied to those inputs, have the ability to create outputs that provide a return to the Company and its shareholders. A business also includes those assets and liabilities that do not necessarily have all the inputs and processes required to produce outputs, but can be integrated with the inputs and processes of the Company to create outputs.

Business combinations are accounted for using the acquisition method whereby identifiable assets acquired and liabilities assumed, including contingent liabilities, are recorded at 100% of their acquisition-date fair values. The acquisition date is the date the Company acquires control over the acquiree. The Company considers all relevant facts and circumstances in determining the acquisition date.

Acquisition related costs, other than costs to issue debt or equity securities of the acquirer, including investment banking fees, legal fees, accounting fees, valuation fees and other professional or consulting fees are expensed as incurred.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports in its financial statements provisional amounts for the items for which the accounting is incomplete. During the measurement period, the Company will retrospectively adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date and, if known, would have affected the measurement of the amounts recognized as of that date. The maximum length of time for the measurement period is one year from the acquisition date.

Accounting Standards Issued but not yet Adopted

The following items are the key accounting standards that have been issued by the IASB but not yet applied by the Company:

(a) International Financial Reporting Standard 9, Financial Instruments (“IFRS 9”)

IFRS 9 was issued in November 2009 and contained requirements for financial assets. This standard addresses classification and measurement of financial assets and replaces the multiple category and measurement models in IAS 39 for debt instruments with a new mixed measurement model having only two categories: amortized cost and fair value through profit or loss. IFRS 9 also replaces the models for measuring equity instruments, and such instruments are either recognized at fair value through profit or loss or at fair value through other comprehensive income. Where such equity instruments are measured at fair value through other comprehensive income, dividends are recognized in profit or loss to the extent not clearly representing a return of investment; however, other gains and losses (including impairments) associated with such instruments remain in accumulated comprehensive income indefinitely.

Requirements for financial liabilities were added in October 2010 and they largely carried forward existing requirements in IAS 39, Financial Instruments — Recognition and Measurement, except that fair value changes due to credit risk for liabilities designated at fair value through profit and loss would generally be recorded in other comprehensive income.

This standard is required to be applied for accounting periods beginning on or after January 1, 2013, with earlier adoption permitted. The Company has not yet assessed the impact of the standard or determined whether it will adopt the standard early.

- 6 -

(b) International Financial Reporting Standard 10, Consolidated Financial Statements (“IFRS 10”)

IFRS 10 was issued in May 2011 and it establishes principles for the presentation and preparation of consolidated financial statements when an entity controls one or more other entities. IFRS 10 replaces the consolidation requirements in SIC-12 Consolidation—Special Purpose Entities and IAS 27 Consolidated and Separate Financial Statements.

This standard is effective for annual periods beginning on or after January 1, 2013. Earlier application is permitted. The Company has not yet assessed the impact of the standard or determined whether it will adopt the standard early.

(c) International Financial Reporting Standard 11, Joint Arrangements (“IFRS 11”)

IFRS 11 was issued in May 2011 and it provides for a more realistic reflection of joint arrangements by focusing on the rights and obligations of the arrangement, rather than its legal form. The standard addresses inconsistencies in the reporting of joint arrangements by requiring a single method to account for interests in jointly controlled entities. IFRS 11 supersedes IAS 31 Interests in Joint Ventures and SIC-13 Jointly Controlled Entities — Non-Monetary Contributions by Ventures.

The standard is effective for annual periods beginning on or after January 1, 2013. Earlier application is permitted. The Company has not yet assessed the impact of the standard or determined whether it will adopt the standard early.

(d) International Financial Reporting Standard 12, Disclosure of Interest in Other Entities (“IFRS 12”)

IFRS 12 was issued in May 2011 and it is a new and comprehensive standard on disclosure requirements for all forms of interests in other entities, including subsidiaries, joint arrangements, associates and unconsolidated structured entities.

The standard is effective for annual periods beginning on or after January 1, 2013. Earlier application is permitted. The Company has not yet assessed the impact of the standard or determined whether it will adopt the standard early.

(e) International Financial Reporting Standard 13, Fair Value Measurement (“IFRS 13”)

IFRS 13 establishes new guidance on fair value measurement and disclosure requirements for IFRS and completes a major project to improve the convergence of IFRS and US GAAP.

The standard is effective for annual periods beginning on or after January 1, 2013. Earlier application is permitted. The Company has not yet assessed the impact of the standard or determined whether it will adopt the standard early.

4. TRANSITION TO IFRS

These financial statements were prepared as described in note 2, including the application of IFRS 1. IFRS 1 sets out the procedures that the Company must follow when it adopts IFRS for the first time as the basis for preparing its consolidated financial statements. The Company is required to establish its IFRS accounting policies for 2011 and, in general, apply these retrospectively to determine the IFRS opening balance sheet as at the transition date of January 1, 2010. The IFRS accounting policies for 2011 include both IFRS in effect currently or those standards expected to be in effect as of December 31, 2011.

IFRS 1 also requires that comparative financial information be provided. As a result, the first date at which the Company has applied IFRS was January 1, 2010 (the “Transition Date”). IFRS 1 requires first-time adopters to retrospectively apply all effective IFRS standards as of the reporting date, December 31, 2011. The standard also permits a number of optional and mandatory exemptions from full retrospective application.

The Company is required to use the following mandatory exemptions as follows:

• Estimates cannot be created or revised using hindsight. The estimates previously made by the Company under Canadian GAAP (“CGAAP”) were not revised for the application of IFRS except where necessary to reflect any difference in accounting policies.

• For non-controlling interests, IFRS 1 lists specific requirements of IAS 27 Consolidated and Separate Financial Statements which are applied prospectively.

- 7 -

The Company has elected to use the following optional exemptions and has made the following adjustments to transition from Canadian GAAP to IFRS:

a) Business Combinations

The Company elected to apply IFRS relating to business combinations prospectively from January 1, 2010. As such, Canadian GAAP balances relating to business combinations entered into before that date have been carried forward.

b) Cumulative Translation Adjustment

The Company has elected to reset the cumulative translation adjustment account, which includes gains and losses arising from the translation of foreign operations, to zero at the date of transition to IFRS as an alternative to calculating the retrospective cumulative translation adjustments required to be in compliance with the principles of IAS 21 for the periods prior to transition.

c) Impairment testing under IAS 36 and IFRS 1 elections

In accordance with IAS 36, the Company performed impairment tests of its Canadian and United States Cash Generating Units (CGU) which includes inventories, mineral properties, plant and equipment, goodwill and reclamation liabilities. The Company estimated fair values using a combination of a discounted cash flow model using the fair value less cost to sell basis (at a discount rate of 10%) and independent valuations to determine the recoverable amount of these CGUs. The recoverable amounts determined for both CGUs were less than the carrying amounts. For the Canadian CGU, the carrying value of the mineral properties and plant and equipment were reduced to estimated fair value and, as a result, the carrying value of goodwill was fully written off. For the United States CGU, the carrying values of the plant and equipment and mineral properties were reduced to estimated fair value.

IFRS 1 allows an entity to elect to measure an item of property, plant and equipment at the date of transition to IFRS at its fair value and use that fair value as its deemed cost at that date. The first time adopter may elect to use a previous CGAAP revaluation of an item of property, plant and equipment at, or before, the date of transition to IFRS as deemed cost at the date of the revaluation, if the revaluation was, at the date of the revaluation, broadly comparable to fair value. The Company has elected to take the lower of cost or fair value of certain of its property, plant and equipment as deemed cost based on appraisal reports prepared by independent third party valuators.

The Company wrote down the carrying value of its Zambian mineral properties to its fair value in the 2009 fiscal year as part of its impairment assessment under Canadian GAAP. The fair value was calculated using most recent comparable transactions at such point in time. This fair value has been used as the ‘deemed cost’ going forward upon transition to IFRS. The impact of this is that no reversal of impairment loss previously taken would be required even if there was an increase in fair value in subsequent periods. There are no other significant assets in the Zambian CGU.

As a result of the transition to IFRS and the reduction of the carrying amounts of PP&E and mineral properties, management recognized the related decrease in deferred tax liability as of January 1, 2010.

A summary of the impairment charges recorded by each CGU on January 1, 2010, by asset class, is as follows:

	Canadian		United States
	Mining		Mining
(in thousands)	Segment		Segment		Total
Property, plant and equipment
Plant and equipment	$	13,009	$	927	$	13,936
Mineral properties		252,267		59,645		311,912
Goodwill		51,028		—		51,028
Transitional impairment loss-pre tax	$	316,304	$	60,572	$	376,876

The Company amortizes its mineral property assets on a units of production basis and includes that amount in the valuation of work-in-progress and concentrate inventories. Since the value of the Company’s mineral property assets is less under IFRS than Canadian GAAP, the amount amortized to inventory is also less. As a result the carrying value of inventory also tends to be less to reflect the lower mineral property amortization cost.

- 8 -

The lower carrying values for the Company’s inventory under IFRS also result in lower net realizable value adjustments being recorded in a particular period when compared to Canadian GAAP.

d) Adoption of IFRS 6 for Exploration and Evaluation Expenditures

The Company has elected to adopt the provisions of IFRS 6 which allow the Company to continue with the current accounting policies regarding the accounting for exploration and evaluation expenditures, with the exception of capitalizing a portion of its exploration spending. Under Canadian GAAP, the Company capitalized a portion of its exploration spending as a component of its carrying value of mineral properties.

Under IFRS, this practice has been discontinued and mineral property exploration expense has increased accordingly. This adjustment has impacted the cash flow split between operating and investing activities for IFRS when compared to Canadian GAAP.

e) Change in foreign exchange translation methodology

Under Canadian GAAP, the Company used the temporal method of foreign exchange translation for its fully-integrated subsidiaries. This included its Zambian and Australian subsidiaries. Under the temporal method, non-monetary assets were converted to the presentation currency using historical foreign exchange rates and the resulting difference between the translation of the balance sheet and income statement was recorded in the statement of operations.

Under IFRS, the temporal method is not recognized and translation occurs using the equivalent of the current rate method under Canadian GAAP. Under this method, all assets and liabilities are treated as monetary and translated to the presentation currency using the foreign exchange rate at the end of the reporting period. Differences between the translation of the balance sheet and the statement of operations are accumulated in an account in equity. The change in translation methodology has resulted in some significant changes in the presentation currency amounts for the Company’s Zambian subsidiary and has also resulted in the reversal of translation foreign exchange income (expense) in the statement of income (loss).

f) Acquisition of OmegaCorp Limited

The Company completed the acquisition of OmegaCorp Limited in 2007 under which it acquired its Zambian subsidiary. Under Canadian GAAP at the time, the Company treated the transaction as an asset acquisition and was required to gross-up the Mutanga project mineral property value and the deferred tax liability by an equal and offsetting amount. In 2009, the Company impaired the value of the Mutanga project to its fair value at the time. As at January 1, 2010, a portion of the deferred tax liability associated with the initial acquisition of the Mutanga project in 2007 still remained under Canadian GAAP. This remaining deferred tax liability has been reversed on the transition to IFRS as IAS 12 does not permit the recognition of a deferred tax liability on the initial recognition of an asset in a transaction that is not a business combination.

g) Flow-through share accounting

Under Canadian GAAP, the Company would record the gross proceeds relating to flow-through shares to share capital at the time of issuance. It would then record a charge (reduction) to share capital at the time the tax benefits of the flow-through shares were renounced to the subscribers. The charge was calculated by multiplying the amount of the renounced tax benefits (which are equal to the proceeds of the flow-through share issue) by the effective tax rate at the time. The offset would go to the deferred tax liability to reflect the fact that the Company could no longer use the tax attributes for its benefit.

Under IFRS, the proceeds from issuing flow-through shares are allocated between the offering of shares and the sale of tax benefits. The allocation is based on the difference (“premium”) between the quoted price of the Company’s existing shares, at the date of closing, and the amount the investor pays for the actual flow-through shares. A liability is recognized for the premium, and is extinguished when the tax effect of the temporary differences, resulting from the renunciation, is recorded. The difference between the liability and the value of the tax assets renounced is recorded as a deferred tax expense. There is no subsequent reduction in share capital.

- 9 -

h) Other transitional items

The income statement has been adjusted for the following additional items not discussed above:

• Depreciation expense — increase due to componentization adjustments on assets at the McClean Lake and White Mesa mills;

• Reclamation asset amortization and liability adjustments — Upon transition, the Company impaired the value of its reclamation assets to nil. As a result, any resulting amortization has been reversed. The change in the net asset value of the reclamation assets has also impacted the amount of the liability adjustment recorded under Canadian GAAP at December 31, 2010;

• Gain / loss on asset disposals — the Company has reversed plant and equipment impairment charges recorded in fiscal 2010 and recalculated the gain / loss on plant and equipment disposals as a result of having adjusted carrying values for its plant and equipment assets;

In preparing its IFRS balance sheets for fiscal 2010, the Company has adjusted amounts previously reported in financial statements prepared in accordance with Canadian GAAP. An explanation of how the transition from Canadian GAAP to IFRS has affected the Company’s balance sheets is set out in the following tables and notes that accompany the tables:

5. ACQUISITION OF WHITE CANYON URANIUM LIMITED

On June 17, 2011, Denison’s offer to acquire all of the outstanding shares of White Canyon Uranium Limited (“WCU”) closed with 96.98% of shares outstanding accepting the offer. Compulsory acquisition proceedings to acquire the remaining shares of White Canyon were initiated on June 20, 2011 and are expected to be completed in early August, 2011.

Denison’s cash offer of AUD $0.24 per WCU share has resulted in a total purchase price of USD$61,027,000 (AUD$57,163,000). All of this amount has been accrued for at June 30, 2011 in the “Business acquisition liability” line on the consolidated balance sheet.

This transaction has been accounted for as a business combination with Denison as the acquirer. The allocation of the purchase price has not been finalized as at the date these interim condensed consolidated financial statements were issued as management is in the process of determining the fair values of identifiable assets acquired and liabilities assumed, measuring the associated deferred income tax assets and liabilities, and determining the value of goodwill, if any. A provisional allocation of the purchase price is as follows:

WCU’s key assets are located in southeastern Utah, near Denison’s White Mesa mill. Its holdings comprise 100% interests in the Daneros producing mine, the Lark Royal advanced project and the Thompson, Geitus, Blue Jay and Marcy Look exploration projects in the Red Canyon district. WCU commenced production of uranium ore in December 2009 from its 100% owned Daneros uranium mine.

The total transaction costs incurred relating to the acquisition and included in general and administrative expenses for the six months ended June 30, 2011 amounted to $1,293,000.

The Company will include the financial results of WCU as part of its USA mining segment. The statement of income (loss) for the period ending June 30, 2011 does not include any results of WCU. The following unaudited pro forma summary presents Denison’s consolidated results as if WCU had been acquired on January 1, 2011. The pro forma information is provided for comparative purposes only and does not necessarily reflect the actual results that would have occurred, nor is it necessarily indicative of future results of operations of the combined companies.

During the six months ended June 2011, the Company has deposited $3,200,000 of additional monies into its collateral account.

Elliot Lake Reclamation Trust Fund

The Company has the obligation to maintain its decommissioned Elliot Lake uranium mine pursuant to a Reclamation Funding Agreement effective September 30, 1994 (“Agreement”) with the Governments of Canada and Ontario. The Agreement requires the Company to deposit 90% of cash flow, after deducting permitted expenses, into the Reclamation Trust Fund. A subsequent amendment to the Agreement provides for the suspension of this obligation to deposit 90% of cash flow into the Reclamation Trust Fund, provided funds are maintained in the Reclamation Trust Fund equal to estimated reclamation spending for the succeeding six calendar years, less interest expected to accrue on the funds during the period. Withdrawals from this Reclamation Trust Fund can only be made with the approval of the Governments of Canada and Ontario to fund Elliot Lake monitoring and site restoration costs. During the six months ended June 2011, the Company has deposited an additional $451,000 (CAD$445,000) into the Elliot Lake Reclamation Trust Fund and withdrew $813,000 (CAD$796,000).

Plant and Equipment-Mining

The Company has a 100% interest in the White Mesa mill located in Utah and mines located in Arizona, Colorado and Utah. Mined ore from these mines is processed at the White Mesa mill.

The Company has a 22.5% interest in the McClean Lake mill and mines located in the Athabasca Basin of Saskatchewan, Canada. The mill is currently on stand-by and is scheduled to remain so throughout 2011 and into 2012. A toll milling agreement has been signed with the participants in the Cigar Lake joint venture that provides for the processing of a substantial portion of the future output of the Cigar Lake mine at the McClean Lake mill, for which the owners of the McClean Lake mill will receive a toll milling fee and other benefits. In determining the amortization rate for the McClean Lake mill, the amount to be amortized has been adjusted to reflect Denison’s expected share of future toll milling mill feed.

Revolving Line of Credit

In June 2011, the Company entered into a $35,000,000 revolving term credit facility (the “facility”) with the Bank of Nova Scotia. The maturity date of the facility is June 29, 2012. This facility replaced a previously existing $60,000,000 revolving term facility.

The facility contains one financial covenant based on maintaining a certain level of tangible net worth. It also has a defined working capital borrowing base calculation that sets limits on the amount of borrowings that the Company can have drawn under the facility at any given time.

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. In addition, each of DMC’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.

- 23 -

Interest payable under the facility is bankers acceptance or LIBOR rate plus a margin or prime rate plus a margin. The facility is subject to standby fees.

As at June 30, 2011, the Company has no outstanding borrowings under the facility (December 31, 2010 — $Nil). At June 30, 2011, approximately $10,055,000 of the facility is being utilized as collateral for certain letters of credit and is not available to draw upon (December 31, 2010 - $19,816,000). During the six months ending June 30, 2011, the Company has not incurred any interest under the facility.

The Company has deferred $122,000 (CAD$118,000) of incremental costs associated with the set-up of the facility. These costs are being amortized over the one year term of the facility. The unamortized portion of the asset is included in “prepaid expenses and other” on the consolidated balance sheet.
