DENISON MINES CORP.

Notes to the Condensed Interim Consolidated Financial Statements for the six months ended June 30, 2013 and 2012

(Unaudited—Expressed in U.S. dollars except for shares and per share amounts)

1. | NATURE OF OPERATIONS

Denison Mines Corp. and its subsidiary companies and joint arrangements (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 Company has a 22.5% interest in the McClean Lake mill located in the Athabasca Basin of Saskatchewan, Canada and varying ownership interests in a number of development and exploration projects located in Canada, Mongolia, Zambia and Namibia. Through its environmental services division, the Company provides mine decommissioning and decommissioned site monitoring services to third parties.

The Company is also the manager of Uranium Participation Corporation (“UPC”), a publicly-listed investment holding company formed to invest substantially all of its assets in uranium oxide concentrates (“U 3 O 8”) and uranium hexafluoride (“UF 6”). The Company has no ownership interest in UPC but receives fees for management services and commissions from the purchase and sale of U 3 O 8 and UF 6 by UPC.

Denison Mines Corp. (“DMC”) is incorporated under the Business Corporations Act (Ontario) and domiciled in Canada. The address of its registered head office is 595 Bay Street, Suite 402, Toronto, Ontario, Canada, M5G 2C2.

2. | BASIS OF PRESENTATION

These condensed interim consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) applicable to the preparation of interim financial statements, including IAS 34, Interim Financial Reporting. The condensed interim consolidated financial statements should be read in conjunction with the annual financial statements for the year ended December 31, 2012.

The Company’s presentation currency is U.S. dollars.

These financial statements were approved by the board of directors for issue on August 8, 2013.

3. | SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies followed in these condensed interim consolidated financial statements are consistent with those applied in the Company’s annual financial statements for the year ended December 31, 2012, except as described below.

Accounting Standards Adopted

The Company has adopted the following new and revised accounting standards, along with any consequential amendments, effective January 1, 2013. These changes were made in accordance with the applicable transitional provisions.

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

IFRS 10 replaces the guidance on control and consolidation in IAS 27 “Consolidated and Separate Financial Statements”, and SIC-12 “Consolidation – Special Purpose Entities”. IFRS 10 requires consolidation of an investee only if the investor possesses power over the investee, has exposure to variable returns from its involvement with the investee and has the ability to use its power over the investee to affect its returns. Detailed guidance is provided on applying the definition of control. The accounting requirements for consolidation have remained largely consistent with IAS 27.

The Company assessed its consolidation conclusions on January 1, 2013 and determined that the adoption of IFRS 10 did not result in any change in the consolidation status of any of its subsidiaries and investees.

- 5 -

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

IFRS 11 supersedes IAS 31 “Interests in Joint Ventures” and requires joint arrangements to be classified either as joint operations or joint ventures depending on the contractual rights and obligations of each investor that jointly controls the arrangement. For joint operations, a company recognizes its share of assets, liabilities, revenues and expenses of the joint operation. An investment in a joint venture is accounted for using the equity method as set out in IAS 28 “Investments in Associates and Joint Ventures”.

The Company has reviewed its joint arrangements and concluded that the adoption of IFRS 11 did not result in any changes in the accounting for its existing joint arrangements. New interests in joint arrangements acquired or entered into during the current year have been accounted for in accordance with IFRS 11.

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 carries forward existing disclosures and also introduces significant additional disclosure requirements that address the nature of, and risks associated with, an entity’s interest in other entities.

The Company has not implemented any disclosure changes in these interim statements as a result of this standard. Additional disclosure will be required in the Company’s annual statements.

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

IFRS 13 establishes new guidance on fair value measurement and related disclosure requirements and clarifies that the measurement of fair value of an asset or liability is based on assumptions that market participants would use when pricing the asset or liability under current market conditions, including assumptions about risk.

The adoption of IFRS 13 by the Company did not require any adjustments to the valuation techniques used by the Company to measure fair value and did not result in any measurement adjustments; however, the adoption of this standard has resulted in additional disclosure about the fair value of financial instruments that are measured on a recurring basis as reported in the interim consolidated financial statements (see note 24).

International Accounting Standard 19, Post-Employment Benefits (“IAS 19”)

IAS 19 was amended to eliminate an entity’s option to defer the recognition of certain gains and losses related to post-employment benefits and require re-measurement of associated assets and liabilities in other comprehensive income.

The Company reviewed its accounting policy for post-employment benefits and concluded that under IAS 19 it would no longer be able to amortize the experience gains associated with its post-employment benefits. In addition, the unamortized experience gain previously reported as a component of the post-employment benefit liability would need to be reclassified to accumulated other comprehensive income (“AOCI”), net of tax.

The Company adopted these amendments retrospectively and adjusted its opening equity as at January 1, 2012 to reflect the unamortized experience gain portion of its post-employment liability as a component of AOCI. Any experience gain amortization amounts previously recorded within operating expenses in the statement of operations have been reversed.

Accounting Standards Issued But Not Yet Applied

The Company has not yet adopted the following new accounting pronouncements which are effective for fiscal periods of the Company beginning on or after January 1, 2014:

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, 2015, with earlier adoption permitted. The Company has not evaluated the impact of adopting this standard.

- 7 -

International Accounting Standard 36, Impairment of Assets (“IAS 36”)

IAS 36 was amended in May 2013 to make small changes to the disclosures required by IAS 36 when an impairment loss is recognized or reversed. The amendments require the disclosure of the recoverable amount of an asset or cash generating unit (“CGU”) at the time an impairment loss has been recognized or reversed and detailed disclosure of how the associated fair value less costs of disposal has been determined.

The amendments are effective for accounting periods beginning on or after January 1, 2014 with earlier adoption permitted. The Company has not evaluated the impact of adopting this additional disclosure.

Comparative Numbers – Change in Classification due to Discontinued Operations

In fiscal 2012, the Company completed its transaction with Energy Fuels Inc. (“EFR”) to sell all of its mining assets and operations located in the United States (“U.S. Mining Division”) and, in conjunction with the sale, reorganize the Company’s capital (see note 4). In accordance with IFRS 5 “Non-current Assets Held for Sale and Discontinued Operations”, the Company has reclassified its fiscal 2012 results in the statement of comprehensive income to include only the Company’s continuing operations in the line item detail of the statement and to disclose the results of its U.S. Mining Division, net of tax, as a single line item amount. Note disclosure relating to the statement of comprehensive income (loss) for fiscal 2012 has also been restated.

4. | ACQUISITIONS AND DIVESTITURES

Acquisition of Fission Energy Corp

On April 26, 2013, Denison completed an arrangement agreement (the “Fission Arrangement”) to acquire a portfolio of assets from Fission Energy Corp. (“Fission”) which included its 60% interest in the Waterbury Lake uranium project, its interests in all other properties in the eastern part of the Athabasca Basin, Quebec and Nunavut, as well as its interests in two joint ventures in Namibia (collectively, the “Assets”).

Under the terms of the Fission Arrangement, Fission shareholders received 0.355 of a common share of Denison, a nominal cash payment of CAD$0.0001 and one common share of a newly-formed publicly traded company, Fission Uranium Corp., for each Fission share held. All of the outstanding options of Fission were exchanged for options to purchase common shares of Denison with a number and exercise price determined by reference to the 0.355 exchange ratio and a volume adjusted market value factor. Share purchase warrants in Fission (“Fission Warrant”) that were outstanding on completion of the Fission Arrangement survived the transaction and may still be exercised in accordance with their terms, so that the holder of a Fission Warrant will receive the number of Denison shares, shares of Fission Uranium Corp and nominal cash consideration which the warrant holder would have received had the Fission Warrants been exercised immediately prior to the Fission Arrangement. The proceeds from the Fission Warrant exercise will be split between Denison and Fission Uranium Corp. and each company will be responsible for issuing its respective shares on the exercise of a Fission Warrant. Cash consideration was also advanced to Fission prior to closing (the “Fission Loan”) and included an amount of CAD$2,437,000 in respect of the expenditures incurred and paid by Fission between January 16, 2013 and April 25, 2013 on properties that were ultimately acquired by Denison.

For accounting purposes, Fission is not considered a business under IFRS 3 “Business Combinations” as at the time of the acquisition it is not capable of generating outputs that can provide a return to Denison. As a result, the Fission Arrangement has been accounted for as an asset acquisition with share based consideration. Transaction costs incurred by Denison related to the Fission Arrangement have been capitalized as part of the consideration amount. Denison is including the results of Fission as part of its Canadian and African mining segments for reporting purposes.

The following table summarizes the fair value of the Fission assets acquired and the liabilities assumed at the acquisition date of April 26, 2013:

|  | Fission |
(in thousands) |  | Fair Value |
Cash and cash equivalents |  | $ | 930 |
Trade and other receivables |  |  | 82 |
Property, plant and equipment |  |  |  |

The total consideration relating to the Fission Arrangement is summarized below:

(in thousands except for share amounts) |  |  |
Fair value of 53,053,284 common shares issued by Denison |  | $ | 66,259 |
Fair value of 1,500,854 common share purchase warrants assumed by Denison |  |  | 827 |
Fair value of 1,985,035 common share options issued by Denison |  |  | 1,321 |
Costs incurred by the Company pursuant to arrangement: |  |  |  |
Fission Loan |  |  | 3,321 |
Transaction costs |  |  | 1,667 |
Fair value of total consideration |  | $ | 73,395 |

The fair value of the common shares issued by Denison totaled $66,259,000. The fair value of the common shares was determined using Denison’s closing share price on April 26, 2013 of CAD$1.27 converted to USD$ using the April 26, 2013 foreign exchange rate of 0.9834.

The fair value of the common share purchase warrants assumed by Denison totaled $827,000 or $0.55 per warrant, on average. The fair value was determined using the Black-Scholes option pricing model with the following assumptions: risk-free interest rate of 0.98%, expected stock price volatility between 40.23% and 56.06%, expected life between 0.60 years and 1.70 years and expected dividend yield of nil%.

The fair value of the common share options issued by Denison to replace those of Fission totaled $1,321,000 or $0.67 per option, on average. The fair value was determined using the Black-Scholes option pricing model with the following assumptions: risk-free interest rate between 0.98% and 1.12%, expected stock price volatility between 39.87% and 84.93%, expected life between 0.20 years and 4.70 years and expected dividend yield of nil%. As at April 26, 2013, all of the options issued by Denison to replace the Fission options are fully-vested.

Acquisition of JNR Resources Inc.

On January 31, 2013, Denison completed a plan of arrangement (the “JNR Arrangement”) to acquire all of the outstanding common shares of JNR Resources Inc. (“JNR”). Pursuant to the JNR Arrangement, the former shareholders of JNR received, for each JNR common share held, 0.073 of a Denison common share (the “Exchange Ratio”). No fractional shares were issued. All of the outstanding options and common share purchase warrants of JNR were exchanged for options and warrants to purchase common shares of Denison with a number and exercise price determined by reference to the Exchange Ratio.

For accounting purposes, JNR Resources is not considered a business under IFRS 3 “Business Combinations” as at the time of the acquisition it is not capable of generating outputs that can provide a return to Denison. As a result, the JNR Arrangement has been accounted for as an asset acquisition with share based consideration. Transaction costs incurred by Denison related to the JNR Arrangement have been capitalized as part of the consideration amount. Denison is including the results of JNR as part of its Canadian mining segment for reporting purposes.

Fair value of total consideration |  | $ | 12,425 |

The fair value of the common shares issued by Denison totaled $10,956,000. The fair value of the common shares was determined using Denison’s closing share price on January 31, 2013 of CAD$1.37 converted to USD$ using the January 31, 2013 foreign exchange rate of 1.0027.

The fair value of the common share purchase warrants issued by Denison to replace those of JNR totaled $17,000 or $0.0615 per warrant. The fair value was determined using the Black-Scholes option pricing model with the following assumptions: risk-free interest rate of 1.16%, expected stock price volatility of 47.58%, expected life of 0.75 years and expected dividend yield of nil%.

The fair value of the common share options issued by Denison to replace those of JNR totaled $131,000 or $0.2262 per option.

Discontinued Operation—U.S. Mining Division Transaction and Denison Capital Reorganization

On June 29, 2012, the Company completed its transaction with EFR to sell all of its mining assets and operations located in the United States (the “U.S. Mining Division”) in exchange for consideration equal to 425,440,872 common shares of EFR (the “EFR Share Consideration”). Immediately following the closing of the sale transaction, Denison completed the remaining steps in the Plan of Arrangement (the “Denison Arrangement”) to reorganize its capital and distribute the EFR Share Consideration to Denison shareholders on a pro rata basis as a return of capital

During the interim reporting periods prior to the sale, the Company tested the U.S. Mining Division for impairment using the fair value of the EFR Share Consideration as the recoverable amount. The recoverable amount on the sale date was determined to be $79,395,000 based on 425,440,872 common shares of EFR to be distributed to the Company’s shareholders, a share price of CAD$0.19 per share and a CAD$ to USD$ foreign exchange rate of 0.9822. The fair value of the EFR share consideration, $79,395,000 has been accounted for as a non-cash distribution of assets to shareholders and has been recorded as a component of Deficit in the statement of financial position.

- 10 -

In performing the impairment tests, the Company concluded that the recoverable amount of the U.S. Mining Division was lower than the carrying value. As a result, the Company recognized cumulative impairment losses of $97,944,000 in the six months ended June 30, 2012 which were allocated on a pro rata basis between plant and equipment and mineral property assets in the U.S. Mining Division’s results. The cumulative impairment loss amount was recognized as follows: $44,079,000 in the three months ended March 31, 2012 and $53,865,000 in the three months ended June 30, 2012.

As a result of the transaction, the Company presented the results of the U.S. Mining Division as discontinued operations and, in accordance with IFRS 5, revised its statement of comprehensive income (loss) to reflect this change in presentation. The condensed consolidated statements of financial position and the condensed consolidated statement of cash flows have not been revised. A summary of the impact of the discontinued operations on the condensed consolidated statement of cash flows is presented below.

Plant and Equipment-Mining

The Company has a 22.5% interest in the McClean Lake mill located in the Athabasca Basin of Saskatchewan, Canada. Commissioning of the mill circuits has begun in anticipation of the start of processing of Cigar Lake ore in 2013. A toll milling agreement has been signed with the participants in the Cigar Lake Joint Venture that provides for the processing 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 mill feed from future toll milling.

Plant and Equipment—Services and Other

The environmental services division of the Company provides mine decommissioning and decommissioned site monitoring services for third parties.

Mineral Properties

The Company has various interests in development and exploration projects located in Canada, Mongolia, Zambia and Namibia which are held directly or through option or joint venture agreements.

Canada

The Company’s mineral property interests in Canada with significant carrying values and their location are:

| • |  | McClean Lake (Saskatchewan) – the Company has a 22.5% interest in the project (includes the Sue D, Sue E, Caribou, McClean North and McClean South deposits);

| • |  | Midwest (Saskatchewan) – the Company has a 25.17% interest in the project (includes the Midwest and Midwest A deposits);

| • |  | Wheeler River (Saskatchewan) – the Company has a 60% interest in the project (includes the Phoenix A and B deposits);

| • |  | Waterbury Lake (Saskatchewan) – the Company has a 60% interest in the project (includes the J Zone deposit) and also has a 2.0% net smelter return royalty on the portion of the project it does not own; and

| • |  | Wolly (Saskatchewan) – the Company has a 22.5% interest in the project.

- 14 -

On January 31, 2013, Denison completed the acquisition JNR and acquired additional mineral property interests in Canada with a fair value of $13,022,000 (see note 4). As a result of the JNR Arrangement, Denison increased its interest in five projects it was already participating in to 100% (which includes Moore Lake) and it acquired interests in nine additional properties.

On April 26, 2013, Denison completed the acquisition of Fission and acquired additional mineral property interests in Canada with a fair value of $66,945,000 (see note 4). As a result of the Fission Arrangement, Denison increased its interest in one project (Johnston Lake) that it was already participating in to 100% and it acquired interests in 27 additional properties.

Mongolia

The Company currently has an 85% interest in and is the managing partner of the Gurvan Saihan Joint Venture (“GSJV”) in Mongolia (includes the Hairhan and Haraat deposits). The other party to the GSJV is the Mongolian government with a 15% interest. The results of the GSJV have been 100% consolidated in these financial statements since the Company exercises control and its partner in the GSJV has a carried interest at this time.

Under the Nuclear Energy Law of Mongolia, the Mongolian participant in the GSJV is entitled to hold a 34% to 51% interest in the GSJV, depending on the amount of historic exploration that was funded by the government of Mongolia, to be acquired at no cost to the Mongolian participant. This interest will be held by Mon-Atom LLC, the Mongolian state owned uranium company.

The Company and Mon-Atom are progressing with restructuring the GSJV to meet the requirements of the Nuclear Energy law, pending government reviews and authorizations. The final restructuring of the GSJV is expected to result in the Company having its interest reduced to 66%. The anticipated timing of the completion of the restructuring is uncertain at this time.

Zambia

The Company has a 100% interest in the Mutanga project (includes the Mutanga and Dibwe deposits) located in Zambia.

Namibia

On April 26, 2013, Denison completed the acquisition of Fission and acquired additional mineral property interests in two projects in Namibia with a fair value of $5,949,000 (see note 4). The most significant of these acquired projects is the Dome project.

The Company currently has an approximate 71% interest in the Dome project and is a party to an earn-in agreement with Rio Tinto Mining and Exploration (“Rio”) that was entered into prior to the Company acquiring control of the project. Under the earn-in agreement, Rio can earn an interest in the Dome project as follows: a) 49% of Denison’s interest in the project by incurring exploration expenditures of $5,000,000 by September 2016 (the “First Stage Earn-In”); b) an additional 15% of Denison’s interest in the project by spending an additional $5,000,000 within two years of completing the First Stage Earn-In (the “Second Stage Earn-In”); and c) an additional 11% of Denison’s interest in the project by funding a bankable feasibility study within five years of completing the Second Stage Earn-In;

Site Restoration: Elliot Lake

The Elliot Lake uranium mine was closed in 1992 and capital works to decommission this site were completed in 1997. The remaining provision is for the estimated cost of monitoring the Tailings Management Areas at the Company and Stanrock sites and for treatment of water discharged from these areas. The Company conducts its activities at both sites pursuant to decommissioning licenses issued by the Canadian Nuclear Safety Commission. The above accrual represents the Company’s best estimate of the present value of the total future reclamation cost based on assumptions as to levels of treatment, which will be required in the future, discounted at 5.26%. The undiscounted amount of estimated future reclamation costs at December 31, 2012 is $27,967,000 (CAD$27,825,000).

Spending on restoration activities at the Elliot Lake site is funded from monies in the Elliot Lake Reclamation Trust fund (see note 9).

Site Restoration: McClean Lake Joint Venture and Midwest Joint Venture

The McClean Lake and Midwest operations are subject to environmental regulations as set out by the Saskatchewan government and the Canadian Nuclear Safety Commission. Cost estimates of the estimated future decommissioning and reclamation activities are prepared periodically and filed with the applicable regulatory authorities for approval. The above accrual represents the Company’s best estimate of the present value of the future reclamation cost contemplated in these cost estimates discounted at 5.26%. The undiscounted amount of estimated future reclamation costs at December 31, 2012 is $9,496,000 (CAD$9,448,000). Reclamation costs are expected to be incurred between 2025 and 2052.

Under the Mineral Industry Environmental Protection Regulations (1996), the Company is required to provide its pro-rata share of financial assurances to the Province. As at June 30, 2013, the Company has provided irrevocable standby letters of credit, from a chartered bank, in favour of Saskatchewan Environment, totalling CAD$9,698,000.

The facility contains a covenant to maintain a level of tangible net worth greater than or equal to the sum of $230,000,000 plus an amount equal to (i) 50% of each equity issue from and including March 31, 2012; and (ii) 50% of positive net income in each fiscal quarter from and including March 31, 2012.

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.

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 a standby fee of 1%.

At June 30, 2013, the Company has no outstanding borrowings under the facility (December 31, 2012—$nil) and it is in compliance with its facility covenants. At June 30, 2013, approximately $9,221,000 of the facility is being utilized as collateral for certain letters of credit and is not available to draw upon (December 31, 2012—$9,748,000).

Options outstanding at June 30, 2013 expire between July 2013 and March 2018.

The fair value of each option granted is estimated on the date of grant using the Black-Scholes option pricing model. The following table outlines the range of assumptions used in the model to determine the fair value of options granted (excluding those granted pursuant to the JNR and Fission acquisitions – refer to note 4):

|  | Six Months Ended |
|  | June 30, 2013 |
Risk-free interest rate |  |  | 1.29 | %
Expected stock price volatility |  |  | 60.2 | %
Expected life |  |  | 3.6 years |
Estimated forfeiture rate |  |  | 4.7 | %
Expected dividend yield |  |  | — |
Fair value per share under options granted |  | CAD$ | 0.58 |

The fair values of stock options with vesting provisions are amortized on a graded method basis as stock-based compensation expense over the applicable vesting periods. Included in the statement of income (loss) is stock-based compensation of $193,000 and $503,000 for the three and six months ended June 30, 2013 and $529,000 and $1,150,000 for the three months and six months ended June 30, 2012. At June 30, 2013, the Company had an additional $734,000 in stock-based compensation expense to be recognized periodically to March 2015.

24. | FAIR VALUE OF FINANCIAL INSTRUMENTS

IFRS requires disclosures about the inputs to fair value measurements, including their classification within a hierarchy that prioritizes the inputs to fair value measurement. The three levels of the fair value hierarchy are:

| • |  | Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities;

| • |  | Level 2 – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and

| • |  | Level 3 – Inputs that are not based on observable market data.

A detailed description of the Company’s financial assets and financial liabilities and its associated risk management in respect thereof are provided in note 26 to the 2012 audited consolidated financial statements. There have been no significant changes in the related financial risks that affect the fair value of the Company’s financial assets and financial liabilities since December 31, 2012.

The following table provides information about financial assets and liabilities measured at fair value in the Company’s statement of financial position and categorized by level according to the significance of the inputs used in making the measurements as at June 30, 2013:

|  | Financial |  |  | Fair |  |  | June 30, 2013 |
|  | Instrument |  |  | Value |  |  | Fair |  |  | Carrying |
(in thousands) |  | Category(1) |  |  | Hierarchy |  |  | Value |  |  | Value |
Financial Assets measured at fair value on a recurring basis: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Investments |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Equity instruments |  |  | Category A |  |  |  | Level 1 |  |  | $ | 896 |  |  | $ | 896 |
Equity instruments |  |  | Category B |  |  |  | Level 1 |  |  |  | 25 |  |  |  | 25 |
|  |  |  |  |  |  |  |  |  | $ | 921 |  |  | $ | 921 |

(1) | Financial instrument designations are as follows: Category A=Financial assets and liabilities at fair value through profit and loss; Category B=Available for sale investments.

The fair value of financial instruments which trade in active markets 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.

25. | COMMITMENTS AND CONTINGENCIES

General Legal Matters

The Company is involved, from time to time, in various legal actions and claims in the ordinary course of business. In the opinion of management, the aggregate amount of any potential liability is not expected to have a material adverse effect on the Company’s financial position or results.

Third Party Indemnities

The Company remains a guarantor under a sales contract included in the sale of the U.S. Mining Division to EFR. The sales contract requires deliveries of 200,000 pounds of U 3 O 8 per year from 2013 to 2017 at a selling price of 95% of the long-term U 3 O 8 price at the time of delivery. Should EFR not be able to deliver for any reason other than “force majeure” as defined under the contract, the Company may be liable to the customer for incremental costs incurred to replace the contracted quantities if the unit price of the replacement quantity is greater than the contracted unit price selling amount. EFR has agreed to indemnify the Company for any future liabilities it may incur related to this guarantee.

The Company has agreed to indemnify EFR against any future liabilities it may incur in connection with ongoing litigation between Denison Mines (USA) Corp (“DUSA”) (a company acquired by EFR as part of the sale of the U.S. Mining Division) and a contractor in respect of a construction project at the White Mesa mill. The outcome of this proceeding has yet to be determined; however, an adverse decision may have a material impact on the Company. In the event that the matter is decided in DUSA’s favour, the Company is entitled to any proceeds that are received or recovered by EFR pursuant to its indemnity.
