DENISON MINES CORP.
Notes to the interim consolidated financial statements for the three months ended March 31, 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 January 1, 2011. Accordingly, the Company has commenced reporting on this basis in these interim consolidated financial statements. In the 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 and IFRS 1. Subject to certain transition elections disclosed in note 4, the Company has consistently applied the same accounting policies in its opening IFRS balance sheet at January 1, 2010 and 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, financial performance and cash flows, 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. Comparative figures for 2010 in these interim consolidated financial statements have been restated to give effect to those changes.

|  | The policies applied in these interim consolidated financial statements are based on IFRS policies as of May 11, 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 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. Note 4 discloses IFRS information for the year ended December 31, 2010 not provided in the 2010 annual financial statements and is material to the understanding of these consolidated financial statements.

#####

3. |  | SIGNIFICANT ACCOUNTING POLICIES

|  | The significant accounting policies used in the preparation of these interim consolidated financial statements are described below:

| (a) |  | Principles of consolidation

|  |  | The financial statements of the Company consolidate the accounts of DMC and its subsidiaries. All intercompany transactions, balances and unrealized gains and losses from intercompany transactions are eliminated on consolidation.

|  |  | Subsidiaries are those entities which DMC controls by having the power to govern the financial and operating policies. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether DMC controls another entity. Subsidiaries are fully consolidated from the date on which control is obtained by DMC and are de-consolidated from the date that control ceases.

|  |  | The Company has various interests in development and exploration projects which are held through option or joint agreements. These have been classified as joint ownership interests under IFRS. These joint ownership interests have been accounted for using the undivided interest method.

| (b) |  | Use of estimates

|  |  | The presentation of consolidated financial statements in conformity with IFRS requires the Company’s management to make estimates and assumptions that affect the amounts reported in these financial statements and related note disclosures. Although the Company regularly reviews the estimates and assumptions that affect these financial statements, actual results may be materially different. Significant estimates and assumptions made by management relate to:

| • |  | the quantities and net realizable value of inventories as to the timing of sales, costs to complete and sales prices;

| • |  | the recoverable amounts of cash generating units (“CGU”) used in impairment testing of long-lived assets including estimates of reserves and resources, production costs, foreign exchange rates, discount rates, inflation and income tax rates;

| • |  | the determination of useful lives, units of production and residual values of property, plant and equipment;

| • |  | the recoverability of and reclamation obligations for property, plant and equipment, including estimation of reclamation costs and timing of expenditures that are impacted by changes in discount rates, foreign exchange rates and environmental and regulatory requirements;

| • |  | the estimated cost of providing post-employment benefits actuarially determined using the projected benefits method;

| • |  | the recognition of deferred income taxes based on estimated tax bases using substantively enacted tax rates expected to apply to taxable income during the years in which the differences are expected to be recovered or settled; and

| • |  | the fair value of stock-based compensation determined using the Black-Scholes option pricing model using expected option forfeitures.

| (c) |  | Foreign currency translation

| (i) |  | Functional and presentation currency

|  |  | Items included in the financial statements of each entity in the DMC group are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). Primary and secondary indicators are used to determine the functional currency (primary indicators have priority over secondary indicators). Primary indicators include the currency that mainly influences sales prices and the currency that mainly influences labour, material and other costs. Secondary indicators include the currency in which funds from financing activities are generated and the currency in which receipts from operating activities are usually retained. For our Canadian, Zambian and Mongolian entities, the local currency has been determined to be the functional currency.

|  |  | The consolidated financial statements are presented in U.S. dollars, unless otherwise stated.

|  |  | The financial statements of entities that have a functional currency different from the presentation currency of DMC (“foreign operations”) are translated into U.S. dollars as follows: assets and liabilities — at the closing rate at the date of the statement of financial position, and income and expenses — at the average rate of the period (as this is considered a reasonable approximation to actual rates). All resulting changes are recognized in other comprehensive incomes as cumulative translation adjustments.

- 6 -

#####

|  |  | When an entity disposes of its entire interest in a foreign operation, or loses control, joint control, or significant influence over a foreign operation, the foreign currency gains or losses accumulated in other comprehensive income related to the foreign operation are recognized in profit or loss. If an entity disposes of part of an interest in another entity which remains a subsidiary, a proportionate amount of foreign currency gains or losses accumulated in other comprehensive income related to the subsidiary is reallocated between controlling and non-controlling interests.

| (ii) |  | Transactions and balances

|  |  | Foreign currency transactions are translated into an entity’s functional currency using the exchange rates prevailing at the dates of the transactions. Generally, foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than an operation’s functional currency are recognized in the statement of income.

| (d) |  | Cash and cash equivalents

|  |  | Cash and cash equivalents include cash on hand, deposits held with banks, and other short-term highly liquid investments with original maturities of three months or less.

| (e) |  | Financial instruments

|  |  | Financial assets and financial liabilities are recognized on the consolidated balance sheet when the Company becomes a party to the contractual provisions of the financial instrument. All financial instruments are required to be measured at fair value on initial recognition. Measurement in subsequent periods is dependent upon the classification of the financial instrument as financial assets and liabilities at fair value through profit and loss (“FVPL”), available-for-sale, loans and receivables, held-to-maturity, or other financial liabilities.

|  |  | Financial assets and financial liabilities classified as FVPL are measured at fair value with changes in those fair values recognized on the consolidated statement of operations. Financial assets classified as available-for-sale are measured at fair value with changes in those fair values recognized in other comprehensive income. Financial assets classified as loans and receivables, held to maturity or other financial liabilities are measured at amortized cost using the effective interest rate method of amortization. Where a financial asset classified as held-to-maturity or available-for-sale has a loss in value which is considered to be other than temporary, the loss is recognized in the results of operations.

|  |  | For financial instruments measured at amortized cost, transaction costs or fees, premiums or discounts earned or incurred are recorded, at inception, net against the fair value of the financial instrument. Interest expense is recorded using the effective interest method.

|  |  | The Company has designated its financial assets and liabilities as follows:

| • |  | Cash and cash equivalents (including restricted cash and investments) are classified as FVPL and any period change in fair value is recorded through the results from operations.

| • |  | Trade and other receivables and Notes receivable are classified as loans and receivables and are measured at amortized cost using the effective interest rate method. Interest income is recorded in net income, as applicable.

| • |  | Investments are classified as available-for-sale and any period change in fair value is recorded through other comprehensive income. Where the investment experiences an other than temporary decline in value, the loss is recognized in the results of operations.

| • |  | Accounts payable and accrued liabilities and Debt obligations are classified as other financial liabilities and are measured at amortized cost using the effective interest rate method. Interest expense is recorded in other income, as applicable.

| (f) |  | Impairment of financial assets

|  |  | At each reporting date, the Company assesses whether there is objective evidence that a financial asset is impaired. If such evidence exists, the Company recognized an impairment loss, as follows:

| (i) |  | Financial assets carried at amortized cost: The loss is the difference between the amortized cost of the loan or receivable and the present value of the estimated future cash flows, discounted using the instrument’s original effective interest rate. The carrying amount of the asset is reduced by this amount either directly or indirectly through the use of an allowance account.

| (ii) |  | Available-for-sale financial assets: The impairment loss is the difference between the original cost of the asset and its fair value at the measurement date, less any impairment losses previously recognized in the statement of income. This amount represents the cumulative loss in accumulated other comprehensive income that is reclassified to net income.

#####

| (g) |  | Inventories

|  |  | Expenditures, including depreciation, depletion and amortization of production assets, incurred in the mining and processing activities that will result in the future concentrate production are deferred and accumulated as ore in stockpiles and in-process and concentrate inventories. These amounts are carried at the lower of average costs or net realizable value (“NRV”). NRV is the difference between the estimated future concentrate price (net of selling costs) and estimated costs to complete production into a saleable form.

|  |  | Stockpiles are comprised of coarse ore that has been extracted from the mine and is available for further processing. Mining production costs are added to the stockpile as incurred and removed from the stockpile based upon the average cost per ton or tonne of ore produced from mines considered to be in commercial production. The current portion of ore in stockpiles represents the amount expected to be processed in the next twelve months.

|  |  | In-process and concentrate inventories include the cost of the ore removed from the stockpile, a pro-rata share of the amortization of the associated mineral property, as well as production costs incurred to process the ore into a saleable product. Processing costs typically include labor, chemical reagents and directly attributable mill overhead expenditures. Items are valued according to the first-in first-out method (FIFO) or at weighted average cost, depending on the type of inventory or work-in-process.

|  |  | Materials and other supplies held for use in the production of inventories are carried at average cost and are not written down below that cost if the finished products in which they will be incorporated are expected to be sold at or above cost. However, when a decline in the price of concentrates indicates that the cost of the finished products exceeds net realizable value, the materials are written down to net realizable value. In such circumstances, the replacement cost of the materials may be the best available measure of their net realizable value.

| (h) |  | Property, plant and equipment

|  |  | Property, plant and equipment are recorded at acquisition or production cost and carried net of depreciation and impairments. Cost includes expenditures that are directly attributable to the acquisition of the asset. Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost can be measured reliably. The carrying amount of a replaced asset is derecognized when replaced. Repairs and maintenance costs are charged to the statement of income during the period in which they are incurred.

|  |  | Depreciation is calculated on a straight line or unit of production basis as appropriate. Where a straight line methodology is used, the assets are depreciated to their estimated residual value over an estimated useful life which ranges from three to fifteen years depending upon the asset type. Where a unit of production methodology is used, the assets are depreciated to their estimated residual value over the useful life defined by management’s best estimate of recoverable reserves and resources in the current mine plan. When assets are retired or sold, the resulting gains or losses are reflected in current earnings as a component of other income or expense. The Company allocates the amount initially recognized in respect of an item of property, plant and equipment to its significant parts and depreciates separately each such part. Residual values, method of depreciation and useful lives of the assets are reviewed annually and adjusted if appropriate.

| (i) |  | Mineral property acquisition, exploration and development costs

|  |  | Costs relating to the acquisition of acquired mineral rights and acquired exploration rights are capitalized.

|  |  | Exploration and evaluation expenditures are expensed as incurred on mineral properties not sufficiently advanced. At the point in time that a mineral property is considered to be sufficiently advanced, it is classified as a development mineral property and all further expenditures for the current year and subsequent years are capitalized as incurred. These costs will include costs of maintaining the site until commercial production, costs to initially delineate the ore body, costs for shaft sinking and access, lateral development, drift development and infrastructure development. Such costs represent the net expenditures incurred and capitalized as at the balance sheet date and do not necessarily reflect present or future values.

|  |  | Once a development mineral property goes into commercial production, the property is classified as “Producing” and the accumulated costs are amortized over the estimated recoverable resources in the current mine plan using a unit of production basis. Commercial production occurs when a property is substantially complete and ready for its intended use.

#####

| (j) |  | Impairment of non-financial assets

|  |  | Property, plant and equipment and intangible assets are tested for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. For the purpose of measuring recoverable amounts, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units or CGUs). The recoverable amount is the higher of a CGU’s fair value less costs to sell and value in use (being the present value of the expected future cash flows of the relevant asset or CGU). An impairment loss is recognized for the amount by which the CGU’s carrying amount exceeds its recoverable amount.

| (k) |  | Borrowing costs

|  |  | Borrowing costs attributable to the acquisition, construction or production of qualifying assets are added to the cost of those assets, until such time as the assets are substantially ready for their intended use. All other borrowing costs are recognized as interest expense in the statement of income in the period in which they are incurred.

| (l) |  | Reclamation provisions

|  |  | Reclamation provisions, any legal and constructive obligation related to the retirement of tangible long-lived assets, are recognized when such obligations are incurred, if a reasonable estimate of the value can be determined. These obligations are measured initially at the present value of expected cash flows using a pre-tax discount rate reflecting risks specific to the liability and the resulting costs are capitalized and added to the carrying value of the related assets. In subsequent periods, the liability is adjusted for the accretion of the discount and the expense is recorded in the income statement. Changes in the amount or timing of the underlying future cash flows are immediately recognized as an increase or decrease in the carrying amounts of the liability and related assets. These costs are amortized to the results of operations over the life of the asset. Reductions in the amount of the liability are first applied against the amount of the net reclamation asset on the books with any residual value being recorded in the statement of operations.

|  |  | The Company’s activities are subject to numerous governmental laws and regulations. Estimates of future reclamation liabilities for asset decommissioning and site restoration are recognized in the period when such liabilities are incurred. These estimates are updated on a periodic basis and are subject to changing laws, regulatory requirements, changing technology and other factors which will be recognized when appropriate. Liabilities related to site restoration include long-term treatment and monitoring costs and incorporate total expected costs net of recoveries. Expenditures incurred to dismantle facilities, restore and monitor closed resource properties are charged against the related reclamation and remediation liability.

| (m) |  | Post-employment benefit obligations

|  |  | The Company assumed the obligation of a predecessor company to provide life insurance, supplemental health care and dental benefits, excluding pensions, to its former Canadian employees who retired from active service prior to 1997. The estimated cost of providing these benefits was actuarially determined using the projected benefits method and is recorded on the balance sheet at its estimated present value. The interest cost on this unfunded liability is being accreted over the remaining lives of this retiree group.

| (n) |  | Stock-based compensation

|  |  | The Company uses a fair value-based method of accounting for stock options to employees, including directors, and to non-employees. The fair value is determined using the Black-Scholes option pricing model on the date of the grant. The cost is recognized on a straight-line graded method basis, adjusted for expected forfeitures, over the applicable vesting period as an increase in stock-based compensation expense and the contributed surplus account. When such stock options are exercised, the proceeds received by the Company, together with the respective amount from contributed surplus, are credited to share capital.

- 9 -

#####

| (o) |  | Provisions

|  |  | Provisions for restructuring costs and legal claims, where applicable, are recognized in other liabilities when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount can be reliably estimated. Provisions are measured at management’s best estimate of the expenditure required to settle the obligation at the end of the reporting period, and are discounted to present value where the effect is material. The Company performs evaluations to identify onerous contracts and, where applicable, records provisions for such contracts.

| (p) |  | Income tax

|  |  | Income taxes are accounted for using the liability method of accounting for deferred income taxes. Under this method, current income taxes are recognized for the estimated income taxes payable for the current period. Deferred income tax assets and liabilities are recognized based on temporary differences between the financial statement carrying values of the existing assets and liabilities and their respective income tax bases using enacted or substantively enacted tax rates expected to apply to taxable income during the years in which the differences are expected to be recovered or settled. The recognition of deferred income tax assets are limited to the amount that is considered “probable” to be realized.

| (q) |  | Flow-Through Common Shares

|  |  | The Company’s Canadian exploration activities have been financed in part through the issuance of flow-through common shares whereby the tax benefits of the eligible exploration expenditures incurred under this arrangement are renounced to the subscribers. 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 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 — with the difference between the liability and the value of the tax assets renounced being recorded as a deferred tax expense. The tax effect of the renunciation is recorded at the time the Company makes the renunciation — which may differ from the effective date of renunciation. If the flow-through shares are not issued at a premium, a liability is not established, and on renunciation the full value of the tax assets renounced is recorded as a deferred tax expense.

| (r) |  | Revenue recognition

|  |  | Revenue from the sale of mineral concentrates is recognized when it is probable that the economic benefits will flow to the Company and delivery has occurred, the sales price and costs incurred with respect to the transaction can be measured reliably and collectability is reasonable assured. For uranium, revenue is typically recognized when delivery is effected by book transfer at the applicable uranium storage facility. For vanadium related products, revenue is typically recognized at the time of shipment to the customer.

|  |  | Revenue from toll milling services is recognized as material is processed in accordance with the specifics of the applicable toll milling agreement. Revenue and unbilled accounts receivable are recorded as related costs are incurred using billing formulas included in the applicable toll milling agreement.

|  |  | Revenue from alternate feed process milling is recognized as material is processed, in accordance with the specifics of the applicable processing agreement. In general, the Company collects a recycling fee for receipt of the material and/or receives the proceeds from the sale of any uranium concentrate and other metals produced. Deferred revenues represent processing proceeds received on delivery of materials but in advance of the required processing activity.

|  |  | Revenue on environmental service contracts is recognized using the percentage of completion method, whereby sales, earnings and unbilled accounts receivable are recorded as related costs are incurred. Earnings rates are adjusted periodically as a result of revisions to projected contract revenues and estimated costs of completion. Losses, if any, are recognized fully when first anticipated. Revenues from engineering services are recognized as the services are provided in accordance with customer agreements.

|  |  | Management fees from UPC are recognized as management services are provided under the contract on a monthly basis. Commission revenue earned on acquisition or sale of U3O8 and UF6 on behalf of UPC (or other parties where Denison acts as an agent) is recognized on the date when title passes.

#####

| (s) |  | Earnings (loss) per share

|  |  | Basic earnings per share (“EPS”) is calculated by dividing the net income (loss) for the period attributable to equity owners of DMC by the weighted average number of common shares outstanding during the period.

|  |  | Diluted EPS is calculated by adjusting the weighted average number of common shares outstanding for dilutive instruments. The number of shares included with respect to options, warrants and similar instruments is computed using the treasury stock method. DMC’s potentially dilutive common shares comprise stock options granted to employees, and warrants.

| (t) |  | Accounting standards issued but not yet applied

|  |  | 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.

4. |  | TRANSITION TO IFRS

|  | These are the first financial statements issued by the Company that will comply with International Financial Reporting Standards (“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.

|  | 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.

- 11 -

#####

| 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.
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 operations.

| 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.

| 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:
