MANAGEMENT PROXY CIRCULAR (all information as at March 28, 2008 unless otherwise noted)

PERSONS MAKING THE SOLICITATION

This Management Proxy Circular (the “Circular”) is furnished in connection with the solicitation of proxies being made by the management of Denison Mines Corp. (“Denison” or the “Company”) for use at the Annual Meeting of the Company’s shareholders (the “Meeting”) to be held on Tuesday, April 29, 2008 at the time and place and for the purposes set forth in the accompanying Notice of Meeting. While it is expected that the solicitation will be made primarily by mail, proxies may be solicited personally or by telephone by directors, officers and employees of the Company.

All costs of this solicitation will be borne by the Company.

APPOINTMENT OF PROXIES

The individuals named in the accompanying form of proxy (the “ Proxy ”) are directors or officers of the Company. A SHAREHOLDER WISHING TO APPOINT SOME OTHER PERSON OR COMPANY (WHO NEED NOT BE A SHAREHOLDER) TO ATTEND AND ACT FOR THE SHAREHOLDER AND ON THE SHAREHOLDER’S BEHALF AT THE MEETING HAS THE RIGHT TO DO SO, EITHER BY INSERTING SUCH PERSON’S OR COMPANY’S NAME IN THE BLANK SPACE PROVIDED IN THE PROXY AND STRIKING OUT THE TWO PRINTED NAMES, OR BY COMPLETING ANOTHER PROXY. No proxy, including the Proxy, will be valid for use at the Meeting, or any adjournment thereof, unless it is completed, dated and signed and delivered to Computershare Investor Services Inc. (“ Computershare ”), Toronto Office, Proxy Department, at 100 University Avenue, 9th Floor, Toronto, Ontario, Canada M5J 2Y1, by 5:00 p.m. (Toronto Time) on April 25 , 2008 . For general inquiries, shareholders may contact Computershare as follows by telephone at 1-800-564-6253 or by e-mail at [email protected] .

If you are a beneficial shareholder and receive these materials through your broker or through another intermediary, please complete and return the form of proxy in accordance with the instructions provided by your broker or other intermediary.

ADVICE TO NON-REGISTERED HOLDERS OF COMMON SHARES

These shareholder materials are being sent to both registered and non-registered owners of common shares in the capital stock of Denison (the “ Common Shares ”). If you are a non-registered owner and Denison or its agent has sent these materials directly to you, then your name, address and information about your share holdings have been obtained in accordance with applicable securities regulatory requirements from the intermediary holding on your behalf.

By choosing to send these materials to you directly, Denison (and not the intermediary holding on your behalf) has assumed responsibility for (i) delivering these materials to you and (ii) executing your proper voting instructions. Please return your voting instructions as specified in the request for voting instructions.

The information set forth in this section is of significant importance to many shareholders of the Company, as a substantial number of shareholders do not hold Common Shares in their own name. Shareholders who do not hold Common Shares in their own name, referred to in this Circular as non-registered holders, should note that only proxies deposited by shareholders whose names appear on the records of the Company as the registered holders of Common Shares can be recognized and acted upon at the Meeting. However, in many cases, Common Shares beneficially owned by a non-registered holder are either:

(a) in the name of an intermediary that the non-registered holder deals with in respect of the Common Shares, such as, among others, banks, trust companies, securities dealers or brokers and trustees or administrators of self-administered RRSPs, RRIFs, RESPs and similar plans; or

(b) in the name of a depositary (such as The Canadian Depositary for Securities Limited or “ CDS ”) of which the intermediary is a participant.

In accordance with Canadian securities laws, Denison has distributed copies of the notice of meeting, this Circular, the form of proxy, the audited financial statements for the year ended December 31, 2007, management’s discussion and analysis and the Auditor’s Report (collectively, the “ meeting materials ”) to CDS and intermediaries for onward distribution to those non-registered holders to whom Denison has not sent the meeting materials directly.

In such cases, intermediaries are required to forward meeting materials to non-registered holders, unless a non-registered holder has waived the right to receive them. Very often, intermediaries will use a service company (such as Broadridge Investor Communications) to forward the meeting materials to non-registered holders.

Non-registered holders who have not waived the right to receive meeting materials will receive either a voting instruction form or, less frequently, a form of proxy. The purpose of these forms is to permit non-registered holders to direct the voting of the Common Shares that they beneficially own. Non-registered holders should follow the procedures set out below, depending on which type of form they receive.

A. Voting Instruction Form. In most cases, a non-registered holder will receive, as part of the meeting materials, a voting instruction form. If the non-registered holder does not wish to attend and vote at the meeting in person (or have another person attend and vote on the non-registered holder’s behalf), the voting instruction form must be completed, signed and returned in accordance with the directions on the form. If a non-registered holder wishes to attend and vote at the Meeting in person (or have another person attend and vote on the non-registered holder’s behalf), the non-registered holder must complete, sign and return the voting instruction form in accordance with the directions provided, and a form of proxy giving the right to attend and vote will be forwarded to the non-registered holder.

Or

Folio -2- /Folio

PAGEBREAK

B. Form of Proxy. Less frequently, a non-registered holder will receive, as part of the meeting materials, a form of proxy that has already been signed by the intermediary (typically by facsimile, stamped signature) which is restricted as to the number of Common Shares beneficially owned by the non-registered holder, but which is otherwise uncompleted. If the non-registered holder does not wish to attend and vote at the Meeting in person (or to have another person attend and vote on the non-registered holder’s behalf), the non-registered holder must complete the form of proxy and deposit it with Computershare as described above. If a non-registered holder wishes to attend and vote at the Meeting in person (or have another person attend and vote on the non-registered holder’s behalf), the non-registered holder must strike out the names of the persons named in the proxy and insert the non-registered holder’s (or such other person’s) name in the blank space provided.

Non-registered holders should follow the instruction on the forms that they receive and contact their intermediaries promptly if they need assistance.

REVOCATION OF PROXIES

A registered shareholder who has given a Proxy may revoke it by an instrument in writing executed by the shareholder or by the shareholder’s attorney authorized in writing or, if the shareholder is a corporation, by a duly authorized officer or attorney of the corporation, and delivered either to the registered office of the Company, at Atrium on Bay, Suite 402, 595 Bay St., Toronto, Ontario, Canada, M5G 2C2, at any time up to and including the last business day preceding the day of the Meeting or any adjournment of it or to the chair of the Meeting on the day of the Meeting or any adjournment of it. Only registered shareholders have the right to revoke a Proxy. Non-registered holders who wish to change their vote must, at least seven days before the Meeting, arrange for their respective intermediaries to revoke the Proxy on their behalf.

A revocation of a Proxy does not affect any matter on which a vote has been taken prior to the revocation.

EXERCISE OF DISCRETION

If the instructions in a Proxy are certain, the Common Shares represented thereby will be voted on any poll by the persons named in the Proxy and, where a choice with respect to any matter to be acted upon has been specified in the Proxy, the Common Shares represented thereby will, on a poll, be voted or withheld from voting in accordance with the specifications so made.

Where no choice has been specified by the shareholder, such Common Shares will, on a poll, be voted in accordance with the notes to the Proxy. In particular, and without limiting the foregoing, a management nominee will vote any Proxy held by him or her in favour of any resolution in respect of which no choice has been specified in the Proxy.

The enclosed Proxy, when properly completed and delivered and not revoked, confers discretionary authority upon the persons appointed proxy holders thereunder to vote with respect to any amendments or variations of matters identified in the Notice of Meeting and with respect to other matters which may properly come before the Meeting. At the time of the printing of this Circular, the management of the Company knows of no such amendment, variation or other matter that may be presented to the Meeting.

In accordance with the provisions of the Business Corporations Act (Ontario) (the “ OBCA ”), the Company will prepare a list of holders of Common Shares on such record date. Each holder of Common Shares named in the list will be entitled to vote the Common Shares shown opposite his or her name on the list at the Meeting except to the extent that (a) the holder has transferred any of his or her Common Shares after the record date, and (b) the transferee of such Common Shares produces properly endorsed share certificates or otherwise establishes that he or she owns such Common Shares and demands, not later than ten days before the Meeting, that his or her name be included in the list before the Meeting, in which case the transferee is entitled to vote such Common Shares at the Meeting.

To the knowledge of the directors and executive officers of the Company, no person, or corporation, beneficially owns, directly or indirectly, or exercises control or direction over, securities carrying more than ten percent of the voting rights attached to voting securities of the Company as of the record date.

To the knowledge of the Company, the only matters to be dealt with at the Meeting are (i) the election of directors of the Company; (ii) the appointment of auditors; and (iii) the receipt of the audited financial statements of the Company for the year ended December 31, 2007 and the auditors report thereon.

Long-Term Incentive Plans — Awards in Most Recently Completed Financial Year

The Company has no Long-Term Incentive Plan in place and therefore there were no awards made under any long-term incentive plan to the Named Executive Officers during the Company’s most recently completed financial year. A “Long-Term Incentive Plan” is a plan providing compensation intended to motivate performance over a period of greater than one financial year, other than a plan for options, SARs or compensation through shares or units that are subject to restrictions on resale.

Option/SAR Grants During the Most Recently Completed Financial Year

The Company’s Plan

The Company’s stock option plan (the “ Stock Option Plan ”) governing the issuance of stock options was established on February 14, 1997 (and amended as approved by shareholders on March 23, 1998, March 22, 2005 and November 20, 2006). The Stock Option Plan complies with the rules set forth for such plans by the TSX.

The major features of the Plan can be summarized as follows:

| • | The Board, or a committee appointed for such purposes, may from time to time grant to
directors, officers, eligible employees of, or consultants to, the Company or its
subsidiaries, or to employees of management companies providing services to the Company
(collectively, the “ Eligible Personnel ”) options to acquire Common Shares in such numbers,
for such terms and at such exercise prices as may be determined by the Board or such
committee. The purpose of the Stock Option Plan is to advance the interests of the Company
by providing Eligible Personnel with a financial incentive for the continued improvement of
the Company’s performance and encouragement to stay with the Company. |
| --- | --- |
| • | The maximum number of Common Shares that may be reserved for issuance for all purposes
under the Stock Option Plan shall not exceed ten percent of the issued and outstanding
shares of the Company at the time of grant subject to a maximum of 20,000,000 shares or
such additional amount as the Company’s shareholders may approve from time to time. This
maximum number includes both Common Shares previously issued upon the exercise of options
over the entire term of the Stock Option Plan since February 14, 1997 and Common Shares
issuable under outstanding options under the Stock Option Plan, as amended. Any Common
Shares subject to a share option which for any reason is cancelled or terminated without
having been exercised will again be available for grant under the Stock Option Plan. The
maximum number of Common Shares that may be reserved for issuance to insiders of the
Company under the Stock Option Plan and under any other share compensation arrangement is
limited to ten percent of the Common Shares outstanding at the time of grant (on a
non-diluted basis). |
| • | The Board has the authority under the Stock Option Plan to establish the option price at
the time each share option is granted. The option price may not be lower than the market
price, for example, the closing price of the Common Shares as traded on the Exchange on the
last trading day preceding the date on which the option is approved by the Board. |

Options granted under the Stock Option Plan must be exercised no later than ten years after the date of grant or as otherwise determined by the Board, and options are not transferable other than by will or the laws of dissent and distribution. Typically, if an optionee ceases to be an Eligible Person for any reason whatsoever other than death, each option held by such optionee will cease to be exercisable 30 days following the termination date (being the date on which such optionee ceases to be an Eligible Person). If an optionee dies,

Folio -11- /Folio

PAGEBREAK

the legal representative of the optionee may exercise the optionee’s options within one year after the date of the optionee’s death but only up to and including the original option expiry date.

The Company provides no financial assistance to facilitate the purchase of Common Shares to directors, officers or employees who hold options granted under the Stock Option Plan. See “Securities Authorized for Issuance under Equity Compensation Stock Option Plan” for further details.

The DMI Plan

As a result of the Denison Arrangement, the Company agreed to assume all of DMI’s obligations under the stock option plan of DMI (the “ DMI Plan ”). As a result, DMI optionholders are now entitled to receive 2.88 Common Shares for each DMI option exercised according to its terms at the time of grant. The Denison Arrangement also resulted in the automatic vesting of all DMI options outstanding on December 1, 2006. On December 1, 2006, an aggregate of 1,411,115 options were outstanding under the DMI Plan, which were restated to give effect to the Denison Arrangement as 4,064,011 options. No further grants can be made under the DMI Plan.

No incentive stock options and no SAR’s were granted to the Named Executive Officers during the year ended December 31, 2007.

AGGREGATED OPTION/SAR EXERCISES DURING THE MOST RECENTLY COMPLETED FINANCIAL YEAR AND FINANCIAL YEAR END OPTION/SAR VALUES

The following table sets out incentive stock options exercised by the Named Executive Officers during the year ended December 31, 2007, as well as the end of period value of stock options held by the Named Executive Officers.

Denison does not have any defined benefit or actuarial plans. In addition, there are no compensatory plans or arrangements in place, including payments to be received from the Company or its subsidiaries, with respect to any of the Named Executive Officers, which would result from the resignation, retirement or any other termination of employment of such person’s employment with the Company and its subsidiaries or from a

Folio -12- /Folio

PAGEBREAK

change of control of the Company or any subsidiary of the Company or a change in the Named Executive Officer’s responsibilities following a change in control, apart from those separately disclosed below.

There were no options or freestanding SARs held by the Named Executive Officers that were re-priced downward during the most recently completed financial year of the Company.

Termination of Employment, Change in Responsibilities and Employment Contracts

All of the Named Executive Officers have written employment agreements with Denison.

The employment agreements of Messrs. Farmer, Hochstein and Anderson contain confidentiality, non-competition and non-solicitation provisions. Base salaries for all three individuals are subject to annual review. Mr. Farmer and Mr. Hochstein are entitled to an annual cash bonus in a quantum to be determined by the Board, and their bonuses are payable based upon the satisfactory achievement of incentive parameters established by the Board at the beginning of each year. Mr. Anderson is eligible for an annual cash bonus in an amount up to 50% of his base salary, 25% of which is based on incentive parameters established by the Board and 75% of which is payable at the discretion of the Board.

The employment agreements of Messrs. Farmer, Hochstein and Anderson contain a provision relating to payment in the event of constructive dismissal, termination of employment or change of control (as defined in each agreement). In the event that Mr. Farmer’s employment is terminated for a reason other than just cause, he will be entitled to a payment equal to his salary for 30 months (“ CEO Notice Payment ”) and a bonus payment in an amount equal to the bonus payment earned by him in the immediately preceding year. In addition, Mr. Farmer will be entitled to a payment equivalent to 19% of the CEO Notice Payment in lieu of benefits. Finally, if Mr. Farmer’s employment is terminated for a reason other than just cause, any of Mr. Farmer’s unvested stock options will automatically vest and be exercisable for a 90-day period.

In the event that Mr. Hochstein’s employment is terminated for a reason other than just cause, he will be entitled to a payment equal to his salary for 30 months (“ P&COO Notice Payment ”) and a bonus payment in an amount equal to the bonus payment earned by him in the immediately preceding year. In addition, Mr. Hochstein will be entitled to a payment equivalent to 19% of the P& COO Notice Payment in lieu of benefits. Finally, if Mr. Hochstein’s employment is terminated for a reason other than just cause, any of Mr. Hochstein’s unvested stock options will automatically vest and be exercisable for a 90-day period.

In the event that Mr. Anderson’s employment is terminated for a reason other than just cause, he will be entitled to a payment equal to his salary and benefits for 24 months and a bonus payment in an amount equal to the bonus payment earned by him in the immediately preceding year. If Mr. Anderson’s employment is terminated for a reason other than just cause, any of Mr. Anderson’s unvested stock options will automatically vest and be exercisable for a 90-day period.

Mr. Roberts also has an employment agreement with a subsidiary of the Company which automatically renews for successive one-year terms unless otherwise terminated. The agreement contains a provision relating to confidentiality, non-competition and non-solicitation. The base salary and discretionary bonus for Mr. Roberts is determined by the Chief Executive Officer and subject to annual review. Mr. Roberts is entitled to a severance payment equal to three months’ salary.

Mr. Shaver’s employment agreement provides that he is entitled to a base salary and discretionary bonus, as determined by the Chief Executive Officer and subject to annual review. Mr. Shaver is entitled to 12 months notice upon termination for any reason.

All options held by directors and employees of the Company vest immediately following a change of control (as defined in the Stock Option Plan) of the issued and outstanding securities of the Company.

COMPENSATION COMMITTEE

The Compensation Committee is responsible for determining the annual base salaries and bonuses paid to directors and senior management of the Company and the benefits offered by the Company. As at December 31, 2007, the Committee was comprised of three members, a majority of whom are “independent” within the meaning of section 1.4 of Multilateral Instrument 52-110MI 52-110 ”): namely: Messrs. W. Robert Dengler, Paul F. Little and Lukas H. Lundin. A discussion of each such director’s independence follows in this Circular under the heading “Statement of Corporate Governance — Board of Directors”.

During the most recently-completed financial year, none of the Committee’s members had any interest in material transactions involving the Company, nor was any member of the Committee indebted to the Company. The duties and responsibilities of the Compensation Committee are set out in this Circular under the heading “Statement of Corporate Governance — Board Committees”. The Committee is scheduled to meet at least annually to receive information on and determine matters regarding executive compensation, in accordance with policies approved by the Board.

Report of the Compensation Committee

The Company’s compensation philosophy for executives continues to follow three underlying principles, namely: (i) to provide a compensation package that encourages and motivates performance; (ii) to be competitive with other companies of similar size and scope of operations so as to attract and retain talented executives; and (iii) to align the interests of its executive officers with the long-term interests of the Company and its shareholders through stock-related programs.

When determining compensation policies and individual compensation levels for executive officers, the Committee takes into consideration a variety of factors. These factors include overall financial and operating performance of the Company, the Committee and the Board’s overall assessment of each executive’s individual performance and contribution towards meeting corporate objectives, levels of responsibility, length of service and industry comparables. No specific level of consideration has been designated for individual factors or performance measures.

Executive compensation is comprised primarily of a base salary and participation in the Company’s Stock Option Plan and employment benefit plans, and may also consist of bonuses and other perquisites which are awarded on an occasional basis.

The salary for each executive officer’s position is primarily determined having regard for the incumbent’s responsibilities, individual performance factors, overall corporate performance, and the assessment of such individuals as presented by management to the Board and the Compensation Committee. The salary is intended to provide the executive officer with a compensation level competitive with base salaries within the industry. Executive officers benefit from improved performance of the Company almost entirely through their participation in the Company’s Stock Option Plan and from time to time by the receipt of bonuses.

Compensation of the CEO

The Compensation Committee met prior to the completion of the Denison Arrangement and considered Mr. Farmer’s salary upon his appointment to the position of Chief Executive Officer on December 1, 2006. The Committee determined and recommended to the Board that the salary of C$400,000 being paid to Mr. Farmer by DMI was appropriate for the Company to adopt following the Denison Arrangement and should continue to be paid to Mr. Farmer in 2007. The Committee applied the principles of compensation and considered the factors outlined above to arrive at this determination.

Folio -14- /Folio

PAGEBREAK

Compensation of the President and Chief Operating Officer

Mr. Hochstein served as Chief Executive Officer of the Company until completion of the Denison Arrangement on December 1, 2006.

On December 19, 2005, the Compensation Committee reviewed Mr. Hochstein’s compensation. The Committee reviewed the Company’s primary corporate goals and objective of enhancing share value and evaluated the President and Chief Operating Officer’s performance in light of such goals and objectives, taking into account industry conditions and financial market conditions during the year. The Committee determined that it was appropriate to recommend to the Board that the Chief Executive Officer receive a ten percent salary increase from C$200,000 to C$220,000 per annum effective January 1, 2006 and that the Chief Executive Officer be awarded a cash bonus equal to $14,598, being the equivalent of one month’s salary. This bonus payment was consistent with the Company-wide bonus paid at the same time equal to one month’s salary for all officers and senior managers in recognition of the positive developments in the Company’s business and individual performance.

The Compensation Committee met again prior to the completion of the Denison Arrangement and considered Mr. Hochstein’s salary in consideration of his new responsibilities as President and Chief Operating Officer of the Company. The Committee determined and recommended to the Board that the salary of C$325,000 paid to Mr. Hochstein in 2006 following the Denison Arrangement continue to be paid to Mr. Hochstein in 2007. The Committee applied the principles of compensation and considered the factors outlined above to arrive at this determination.

Stock Option Plan

Another component of the executive officers’ compensation is stock options. The Compensation Committee may from time to time grant stock options to executive officers under the Company’s Stock Option Plan. All grants of options are reviewed and approved by the Board. Grants of stock options are intended to emphasize the executive officers’ commitment to the Company’s growth and the enhancement of share value and to reward executive officers for the Company’s performance through appreciation in equity values. The grant of stock options, as a key component of the executive compensation package, enables the Company to attract and retain qualified executives. Options are generally reviewed annually and are granted to newly hired executive officers at the time of their initial employment. The amount and terms of outstanding options held by an executive are taken into account when determining whether and how new option grants should be made to the executive. The number of Common Shares which may be subject to option under the Stock Option Plan in favour of any one individual is limited under the terms of the Stock Option Plan and the limit cannot be increased without shareholder or regulatory approval. No stock option grants were made to Named Executive Officers during the most recently completed financial year.

COMPENSATION OF DIRECTORS

Remuneration

Prior to December 1, 2006, none of the directors were compensated by the Company, nor its subsidiaries for their services in their capacity as directors, nor were any amounts paid to directors for committee participation or special assignments. All expenses incurred by directors in respect of their duties were, and continue to be, reimbursed by the Company.

Effective December 1, 2006, the Company pays an annual retainer to each director, other than Messrs. Farmer and Hochstein. Given the importance of attracting and retaining desirable board candidates, the Board approved the new compensation arrangement for directors upon the recommendation of the Compensation Committee. In making this recommendation, the Committee considered directors’ compensation offered by similar companies, its directors’ time commitments and the risks and responsibilities that the directors of the Company assume in keeping with the roles of the Board and the standing committees. The Committee also considered the compensation paid by DMI to its directors.

Folio -16- /Folio

PAGEBREAK

As approved by the Board, the annual retainer paid to each director is C$15,000. Denison also commenced paying special fees to certain members of its Board starting December 1, 2006, namely: the Chairman of the Board, who receives a special fee of C$5,000 and the Chair of the Audit Committee, who receives a special fee of C$4,000 per annum.

Effective December 1, 2006, the Company also pays meeting fees to its directors, other than Messrs. Farmer and Hochstein. The attendance fee for Board meetings and committee meetings is C$1,200 for personal attendance and C$800 for attendance by telephone.

STATEMENT OF CORPORATE GOVERNANCE PRACTICE Presented by the Corporate Governance and Nominating Committee

This statement of corporate governance practices is made with reference to National Policy 58-201, Corporate Governance Guidelines and National Instrument 58-101, Disclosure of Corporate Governance Practices (collectively, the “ Governance Guidelines ”) of the Canadian Securities Administrators (“ CSA ”).

Major securities regulatory changes in the United States affecting the Company have come into effect over the last several years. Many of these changes arise from the Sarbanes-Oxley Act of 2002 (“ SOX ”), and subsequent rules and regulations issued by the United States Securities and Exchange Commission.

The Corporate Governance and Nominating Committee has closely monitored the various changes and proposed changes in the regulatory environment and, where applicable, amended its governance practices to align with these changes that are currently in effect.

In accordance with the Governance Guidelines, the Company has chosen to disclose its system of corporate governance in this Circular. The following text sets forth the steps taken by the Company in order to comply with the Governance Guidelines and its system of corporate governance now in force.

The Board has considered the relationship and status of each director. The Board currently consists of ten directors, a majority of whom are independent.

Messrs. Farmer and Hochstein are not independent as executive officers of the Company. Mr. Lundin, Chairman of the Board, may not be considered independent due to his involvement in management of the Company. The remaining directors, Messrs. Craig, Dengler, Edgar, Little, Rand and Romanow and Ms Stefan do not have any material business relationships with the Company, and are therefore considered independent under the Governance Guidelines, and are otherwise independent under MI 52-110 for purposes of sitting on the Company’s Audit Committee.

Several of the directors of the Company serve as directors of other reporting issuers. Currently, the following directors serve on the boards of directors of other public companies as listed below:

Mandate of the Board

The Board has adopted a mandate which acknowledges its stewardship responsibilities. The Board’s principal responsibilities are to supervise and evaluate management, to oversee the conduct of the Company’s business, to set policies appropriate for the business of the Company and to approve corporate strategies and goals. The Board is to carry out its mandate in a manner consistent with the fundamental objective of enhancing shareholder value.

In discharging its stewardship over the Company, the Board has undertaken the following specific duties and responsibilities: (i) satisfying itself as to the integrity of the Chief Executive Officer and other executive officers and as to a culture of integrity throughout the Company; (ii) approving, supervising and providing guidance to management on the Company’s strategic planning process; (iii) identifying the principal risks of the Company’s business and ensuring management’s implementation and assessment of appropriate risk management systems; (iv) ensuring that the Company has highly qualified management and adequate and effective succession plans for senior management; (v) overseeing the Company’s communications policy with its shareholders and with the public generally; (vi) assessing directly and through its Audit Committee, the integrity of the Company’s internal control and management information systems; and (vii) providing for the independent functioning of the Board.

To assist the Board in its responsibilities, the Board has established four standing committees: the Audit Committee, the Compensation Committee, the Corporate Governance and Nominating Committee and the Environment, Health and Safety Committee. Each committee has a written mandate and reviews its mandate annually.

Folio -20- /Folio

PAGEBREAK

Board Independence

The Board believes that adequate structures and processes are in place to facilitate the functioning of the Board independently of management. Each of the Audit Committee and Corporate Governance and Nominating Committee are entirely composed of directors who are independent within the meaning of the Governance Guidelines, and the Compensation Committee and the Environment, Health and Safety Committee are each composed of a majority of directors who are independent within the meaning of the Governance Guidelines. In addition, it is common practice for the Chairman to delegate the chair to Mr. Paul Little, the Lead Director, during Board meetings.

The Board regularly sets aside a portion of each meeting to meet without management and non-independent directors present. In addition, the mandates of the Board and the Corporate Governance and Nominating Committee require procedures be implemented at such times as are desirable or necessary to enable the Board to function independently of management and to facilitate open and candid discussion among its independent directors. Furthermore, individual directors may, in appropriate circumstances and with the authorization of the applicable committee of the Board or the Chairman, engage independent advisors at the expense of the Company.

The Board has appointed Mr. Paul F. Little, an independent director, as Lead Director to act as effective leader of the Board, to ensure that the Board’s agenda will enable it to successfully carry out its duties and to provide leadership for the Board’s independent directors.

Orientation and Continuing Education

The Board encourages directors and senior management to participate in appropriate professional and personal development activities, courses and programs, and supports management’s commitment to the training and development of all permanent employees. In addition, the Chief Executive Officer reviews with each new Board member: (i) information and materials regarding the nature and operations of the Company’s business, including the role of the Board, its committees and directors; (ii) the legal obligations of a director of the Company and other matters required to be addressed under any orientation and education program required for new recruits to the Board. The Company’s outside legal counsel also provides directors and senior officers of the Company with summary updates of any developments relating to the duties and responsibilities of directors and officers and to any other corporate governance matters. In addition, the Board will provide any further continuing education opportunities for all directors, where required, so that individual directors may maintain or enhance their skills and abilities as directors, as well as to ensure that their knowledge and understanding of the Company’s business remains current.

Ethical Business Conduct

The Company is committed to conducting its business in compliance with the law and the highest ethical standards. Accordingly, the Company has adopted a written Code of Ethics (the “ Code ”) applicable to directors, officers and all employees of the Company. Directors, officers or employees who have concerns or questions about violations of laws, rules or regulations, or of the Code are required to report them to the Corporate Secretary or to the Chair of the Company’s Audit Committee. Following receipt of any complaints, the Corporate Secretary or Chair of the Audit Committee, as the case may be, will investigate each matter so reported and report to the Audit Committee. The Audit Committee will have primary authority and responsibility for monitoring compliance with and enforcing the Code, subject to the supervision of the Board of Directors. The Company encourages all directors, officers, and employees to report promptly any suspected violation of the Code to the Corporate Secretary or Chair of the Audit Committee. The Company does not tolerate any retaliation for reports or complaints regarding suspected violations of the Code that were made in good faith.

All directors, officers and employees have an obligation to act in the best interest of the Company. Any situation that presents an actual or potential conflict between a director, officer or employee’s personal interests and the interests of the Company are to be reported to the Chair of the Company’s Audit Committee.

Folio -21- /Folio

PAGEBREAK

The Code is available on the Company’s website and has been filed on and is accessible through SEDAR on the Company’s profile at www.sedar.com.

The Audit Committee has also established a Policy and Procedures for the Receipt, Retention and Treatment of Complaints Regarding Accounting, Internal Accounting Controls or Auditing Matters (the " Whistleblower Policy ”), to encourage employees, officers and directors to raise concerns regarding accounting, internal controls or auditing matters, on a confidential basis free from discrimination, retaliation or harassment.

Board Committees

The Board has established four committees: the Audit Committee, the Compensation Committee, the Corporate Governance and Nominating Committee and the Environment, Health and Safety Committee.

The Audit Committee

The Audit Committee is composed of three directors. Effective December 1, 2006, the members of the Audit Committee consist of: Paul F. Little, William A. Rand and Catherine J.G. Stefan, all of whom are independent and financially literate for the purposes of MI 52-110. All three are considered by the Company to have financial expertise within the meaning of SOX. Mr. Rand has a commerce degree with a major in accounting and a law degree, with extensive experience in corporate finance. Moreover, Mr. Rand has been actively involved as an audit committee member for many years on a number of public companies. Mr. Little is a Chartered Accountant, with an MBA (Finance) and has held the position of Chief Financial Officer for several companies. Ms Stefan is a Chartered Accountant with a B. Comm. In addition, she has held the position of Chief Operating Officer of a public company.

The Audit Committee oversees the accounting and financial reporting processes of the Company and its subsidiaries and all audits and external reviews of the financial statements of the Company, on behalf of the Board, and has general responsibility for oversight of internal controls, and accounting and auditing activities of the Company and its subsidiaries. All auditing services and non-audit services to be provided to the Company by the Company’s auditors are pre-approved by the Audit Committee. The Committee reviews, on a continuous basis, any reports prepared by the Company’s external auditors relating to the Company’s accounting policies and procedures, as well as internal control procedures and systems. The Committee is also responsible for examining all financial information, including annual and quarterly financial statements, prepared for securities commissions and similar regulatory bodies prior to filing or delivery of the same. The Audit Committee also oversees the annual audit process, the quarterly review engagements, the Company’s internal accounting controls, the Company’s Code and Whistleblower Policy, any complaints and concerns regarding accounting, internal control or audit matters and the resolution of issues identified by the Company’s external auditors. The Audit Committee recommends to the Board the firm of independent auditors to be nominated for appointment by the shareholders. The Audit Committee meets a minimum of four times a year.

The Compensation Committee

The Compensation Committee is comprised of three directors, a majority of whom are independent directors within the meaning of the Governance Guidelines. Effective December 1, 2006, the Compensation Committee consists of W. Robert Dengler, Paul F. Little and Lukas H. Lundin. The Compensation Committee evaluates the Chief Executive Officer’s performance and establishes executive and senior officer compensation, determines the general compensation structure, policies and programs of the Company, including the extent and level of participation in incentive programs in conjunction with the Board, and delivers an annual report to shareholders on executive compensation. The Compensation Committee has also been mandated to review the adequacy and form of the compensation of directors and to ensure that such compensation realistically reflects the responsibilities and risk involved in being an effective director. The Compensation Committee is intended to meet at least annually.

Folio -22- /Folio

PAGEBREAK

The Environment, Health and Safety Committee

The Environment, Health and Safety Committee consists of three directors, the majority of whom are independent within the meaning of the Governance Guidelines. Effective December 1, 2006, the Environment, Health and Safety Committee includes: John H. Craig, W. Robert Dengler and Ron F. Hochstein. Due to the complexity of the uranium exploration, mining and milling and radioactive waste recycle/disposal industry, the Board determined that it was appropriate that a member of management sit on the Environment, Health and Safety Committee to ensure that technical expertise is properly brought before the Committee. Accordingly, Mr. Hochstein, President and Chief Operating Officer, is a member of the Committee. The mining and milling industry, by its very nature, can have a significant impact on the natural environment. As a result, environmental planning and compliance must play an ever-increasing part in the operations of any company engaged in these activities. The Company takes these issues very seriously and has established the Environment, Health and Safety Committee to oversee the Company’s efforts to act in a responsible and concerned manner with respect to matters affecting the environment, health and safety. The Company’s Environment, Health and Safety Committee meets at least once in each quarter in which the Board holds a meeting.

The Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee consists of three directors, all of whom are independent within the meaning of the Governance Guidelines. Effective December 1, 2006, the Corporate Governance and Nominating Committee members include: John H. Craig, Brian D. Edgar and Roy J. Romanow. The Corporate Governance and Nominating Committee is responsible for developing and monitoring the Company’s approach to corporate governance issues. The Committee oversees the effective functioning of the Board, oversees the relationship between the Board and management, ensures that the Board can function independently of management at such times as is desirable or necessary, identifies individuals qualified to become new Board members and recommends to the Board the director nominees at each annual meeting of shareholders and, with the assistance of the Board and where necessary, develops an orientation and education program for new recruits to the Board. In identifying possible nominees to the Board, the Corporate Governance and Nominating Committee considers the competencies and skills necessary for the Board as a whole, the skills of existing directors and the competencies and skills each new nominee will bring to the Board, as well as whether or not each nominee will devote sufficient time and resources to the Board. The Corporate Governance and Nominating Committee also annually reviews and makes recommendations to the Board with respect to: (i) the size and composition of the Board; (ii) the appropriateness of the committees of the Board; and (iii) the effectiveness and contribution of the Board, its committees and individual directors, having reference to their respective mandates, charters and position descriptions and (iv) reviews and recommends to the Board amendments to the Company’s Board policies and guidelines. In addition, the Committee delivers an annual statement on corporate governance to the Board for inclusion in either the Company’s annual report or management proxy circular. The Corporate Governance and Nominating Committee is intended to meet at least annually.

Review of Adequacy and Form of Compensation of Directors

The extent and level of directors’ compensation is determined by the Board, as a whole, after considering the recommendations of the Compensation Committee, which has been mandated to review the adequacy and form of the compensation of directors and to ensure that such compensation realistically reflects the responsibilities and risk involved in being an effective director.

Position Descriptions of Management and the Board

The Board, together with the Company’s Chief Executive Officer, has developed position descriptions for the Board, the Chair of the Board, the Chairs of Board Committees and for the Chief Executive Officer, including the definition of the limits to management’s responsibilities. Under these position descriptions, the Board has delegated the day-to-day management of the business and affairs of the Company to executive officers of the

Folio -23- /Folio

PAGEBREAK

Company, subject to the extent and limits defined by the Board. Generally, operations in the ordinary course or that are not in the ordinary course and do not exceed material levels of expenditures or commitment on the part of the Company have been delegated to management. Decisions relating to matters that are not in the ordinary course and that involve material expenditures or commitments on the part of the Company generally require prior approval of the Board. As the Board has plenary power, any responsibility which is not delegated to management or a Board committee remains with the Board. The Chief Executive Officer reviews corporate objectives with the Board on a quarterly basis. In this manner, the Board approves or develops the corporate objectives which the Chief Executive Officer is responsible for meeting.

Shareholder Communications

The Board has put structures in place to ensure effective communication between the Company, its shareholders and the public. The Company has established an investor relations and corporate development procedure where shareholder concerns are dealt with on an individual basis, usually by providing requested information. Significant shareholder concerns are brought to the attention of management or the Board. Shareholders are informed of developments in the Company by the issuance of timely press releases which are concurrently posted to the Company’s website.

Under its mandate, the Board is required to oversee the Company’s communications policy. The Board monitors the policies and procedures that are in place to provide for effective communication by the Company with its shareholders and with the public generally, including effective means to enable shareholders to communicate with senior management and the Board. The Board also monitors the policies and procedures that are in place to ensure a strong, cohesive, sustained and positive image of the Company with shareholders, governments and the public generally.

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007 (Expressed in U.S. Dollars, Unless Otherwise Noted)

INTRODUCTION

This Management’s Discussion and Analysis (“MD&A”) of Denison Mines Corp. and its subsidiary companies and joint ventures (collectively, “Denison” or the “Company”) provides a detailed analysis of the Company’s business and compares its financial results with those of the previous year. This MD&A is dated as of March 18, 2008 and should be read in conjunction with, and is qualified by, the Company’s audited consolidated financial statements and related notes for the year ended December 31, 2007. The financial statements are prepared in accordance with generally accepted accounting principles in Canada with a discussion in Note 28 of the material differences between Canadian and United States generally accepted accounting principles and practices affecting the Company. All dollar amounts are expressed in U.S. dollars, unless otherwise noted.

Other continuous disclosure documents, including the Company’s press releases, quarterly and annual reports, Annual Information Form and Form 40-F are available through its filings with the securities regulatory authorities in Canada at www.sedar.com and the United States at sec.gov/edgar.shtml

In August 2006, the Company changed its fiscal year end from September 30 to December 31 to align its reporting periods with that of its peers in the uranium industry. The Company elected to use a 15-month period ending December 31, 2006 for its audited consolidated financial statements as permitted under Canadian securities regulations. References to “2006” and “2005” refer to the 15-month period ended December 31, 2006 and year ended September 30, 2005. References to 2007 refer to the year ended December 31, 2007.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This MD&A contains “forward-looking statements”, within the meaning of the United States Private Securities Litigation Reform Act of 1995 and similar Canadian legislation, concerning the business, operations and financial performance and condition of Denison.

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

Denison is a diversified, growth-oriented, intermediate uranium producer with active uranium mining projects in both the U.S. and Canada and development projects in Canada, Zambia and Mongolia. Denison expects production of between 3.6 to 6.0 million pounds of uranium oxide in concentrates (“U 3 O 8 ”) by 2011. Denison’s assets include an interest in 2 of the 4 licensed and operating conventional uranium mills in North America, with its 100% ownership of the White Mesa mill in Utah and its 22.5% ownership of the McClean Lake mill in Saskatchewan. Both mills are fully permitted and operating. The Company also produces vanadium as a co-product from some of its mines in Colorado and Utah. The Company is also in the business of recycling uranium-bearing waste materials, referred to as “alternate feed materials”, for the recovery of uranium, alone or in combination with other metals, at the Company’s White Mesa mill.

Denison enjoys a global portfolio of world-class exploration projects, including properties in close proximity to the Company’s mills in the Athabasca Basin in Saskatchewan and in the Colorado Plateau, Henry Mountains and Arizona Strip regions of the southwestern United States. Denison also has exploration and development properties in Mongolia, Zambia and, indirectly through its investments, in Australia.

Denison is the manager of Uranium Participation Corporation (“UPC”), a publicly traded company which invests in uranium oxide in concentrates and uranium hexafluoride. Denison is also engaged in mine decommissioning and environmental services through its Denison Environmental Services (“DES”) division.

The Uranium Industry

Commercial nuclear power generation began over 50 years ago and now generates as much global electricity as was produced in 1960 by all sources. The low operating cost of nuclear power generation and the increasing concern for the environment and climate change are driving a nuclear renaissance. China, India and Russia are proceeding with ambitious plans for new nuclear power plants. Many companies in the United States have filed applications for a combined construction and operating licence to build new nuclear reactors. Countries such as Egypt, United Arab Emirates, Thailand and Turkey are actively considering building nuclear power plants.

There are now 104 operating nuclear reactors in the United States and a total of 439 operating worldwide in 30 countries, representing a total world nuclear capacity of 372.1 gigawatts. A further 34 reactors with a capacity of 27.8 gigawatts are under construction in 12 countries and an additional 93 reactors (100.6 gigawatts) are planned. With the only significant commercial use for uranium being fuel for nuclear reactors, it follows that the nuclear renaissance will have a significant effect on future uranium demand.

Uranium Supply and Demand

The world’s operating nuclear power reactors require approximately 180 million pounds of U 3 O 8 per year. As nuclear power capacity increases, the uranium fuel requirement also increases and is estimated to rise to approximately 187 million pounds U 3 O 8 by 2010 and approximately 212 million pounds U 3 O 8 by 2015. Demand for uranium can be supplied through either primary production (newly mined uranium) or secondary sources (inventories, down blending of weapon grade material and reprocessing fuel rods). Secondary sources are of particular importance to the uranium industry when compared to other commodity markets.

Over the four-year period 2000—2003, annual global primary uranium production averaged 93.1 million pounds of uranium. In response to increasing uranium prices, worldwide uranium production rose to 104.6 million pounds in 2004 and to 108.1 million pounds in 2005; however, production decreased in 2006 to 102.5 million pounds as a result of problems at several production centres. 2007 production is estimated at 107 million pounds. Canada and Australia currently account for over 41% of the world’s production. The United States’ production represented a little over 4.4%, or 4.7 million pounds of uranium in 2007. During the last decade, takeovers, mergers and closures have consolidated the uranium production industry. Based on preliminary 2007 production figures, seven companies accounted for over 88% of primary production while the six largest uranium mines produced over 56% of the aggregate global production.

Primary uranium production only supplies approximately 60% of the total annual requirements of nuclear power generators. The balance of requirements are met from secondary sources of supply, which include inventories held by producers and utilities, government inventories, uranium recycled from government stockpiles and uranium recycled from nuclear weapons. The recycling of highly enriched uranium (“HEU”) from former warheads in the Russian Federation is a unique subset of secondary supply. Surplus fissile military materials are converted in Russia from HEU into low enriched uranium (“LEU”) suitable for use in nuclear reactors. In February 1993, the United States and Russia entered into an agreement (the “Russian HEU Agreement”) which provided for the United States to purchase 500 metric tons of Russian HEU over a 20-year period. In April 1996, the USEC Privatization Act gave Russia and a three company consortium composed of Cameco Corporation (“Cameco”), AREVA Group (“AREVA”) and NUKEM, Inc., the authority to sell the natural uranium feed component (in the form of UF 6 ) derived from the LEU (the “HEU Feed”) in the United States over the 20-year period into the commercial U.S. uranium market under defined annual quotas. The USEC Privatization Act provides a framework for the introduction of this Russian HEU Feed into the U.S. commercial uranium market. Russia has been selling this HEU Feed through long-term supply agreements directly with U.S. utilities and the three companies.

The Russian HEU Agreement terminates in 2013 and Russia has formally stated that it will not be renewed, as had once been anticipated. Additionally, as a result of the dramatic rise in uranium and enrichment prices of the past two years, Russia has notified all of the parties to the HEU Agreement that the previously agreed pricing can no longer stand. Discussions have begun to renegotiate the component prices among the parties and are expected to be completed later this year.

Based upon recent assessments of future secondary uranium supply, the uranium industry’s scheduled uranium production forecast and expected nuclear generating capacity, there is a growing requirement for increased uranium production to meet the forecast needs of reactors world-wide. Based upon the most recent assessment of market trends published by The Ux Consulting Company LLC in their January 2008 edition of “The Uranium Market Outlook” under Reference Case conditions, uranium production to support Western reactors will need to expand from its 2007 level of 107 million pounds, up to 152 million pounds in 2010 and reach 212 million pounds by 2015.

Uranium Prices

Most of the countries that use nuclear-generated electricity do not have a sufficient domestic uranium supply to fuel their nuclear power reactors, and their electric utilities secure most of their required uranium supply by entering into medium-term and long-term contracts with foreign uranium producers and other suppliers. These contracts usually provide for deliveries to begin one to three years after they are signed and to continue for several years thereafter. In awarding medium-term and long-term contracts, electric utilities consider, in addition to the commercial terms offered, the producer’s or supplier’s uranium reserves, record of performance and costs, all of which are important to the producer’s or supplier’s ability to fulfill long-term supply commitments. Under medium-term and long-term contracts, prices are established by a number of methods, including base prices adjusted by inflation indices, reference prices (generally spot price indicators but also long-term reference prices) and annual price negotiations. Contracts may also contain floor prices, ceiling prices, and other negotiated provisions which affect the amount paid by the buyer to the seller. Under these contracts the actual price mechanisms are usually confidential.

Electric utilities procure their remaining requirements through spot and near-term purchases from uranium producers and other suppliers, including other utilities holding excess inventory and governments.

Over the period from 1996 through 2004, annual spot market demand averaged just under 20 million pounds U 3 O 8 or about 12% of the annual world consumption, but had jumped to about 35 million pounds in 2005 and 2006 as the rebuilding of utility inventories commenced, and investors and hedge funds entered the market as significant buyers. Spot market volume returned to its traditional level of approximately 20 million pounds in 2007.

Historically, spot prices have been more volatile than long-term contract prices. In December 2000, the spot price reached an all-time low of $7.10 per pound. The uranium price increased at a moderate rate reaching 14.50 per pound U 3 O 8 by the end of 2003. The spot price increased steadily from that date reaching $72.00 by the end of 2006. A further market impact in October 2006 was the announcement of the flooding and indefinite postponement of the start up of the Cigar Lake mine in northern Saskatchewan. The Cigar Lake mine was scheduled to ramp up to an annual production rate of 18.0 million pounds by 2008. Producers were also active in the spot market, purchasing material to fill contractual demand, which they could not supply due to production issues at their respective operations. During the first half of 2007, the spot price continued its rapid rise reaching a peak of $136.00 in June 2007. At the end of June 2007, the spot price dropped $3.00, the first decline in the spot price since May of 2003. In the last half of the year, the spot price was very volatile, dropping to $75.00 in October, then rebounding to $95.00 in December. Prices have continued to be volatile in 2008. As of the date hereof, the uranium spot price is $74.00 per pound U 3 O 8 .

The long-term uranium price has undergone a similar increase over the past several years, but with significantly less volatility, rising from just under $11.00 per pound U 3 O 8 , at the end of 2002, to $95.00 per pound in May 2007. Since that time the long-term price has remained at $95.00 per pound U 3 O 8 . The long-term price rose due to increased demand from utilities as they placed more of their requirements under contract.

Future uranium prices will be influenced by increased demand from new reactors being constructed or planned in many parts of the world, as well as the amount of incremental supply made available to the market from the remaining excess inventories, HEU feed supplies, other stockpiles, and the availability of increased or new production from other uranium producers.

Competition

Uranium production is international in scope and is characterized by a relatively small number of companies operating in only a few countries. In 2007, four Western companies, Cameco, AREVA, Rio Tinto plc and BHP Billiton Limited produced approximately 58.4% of total world output. Most of the world’s production was from Canada and Australia which produced a combined 41.6% of global uranium output in 2007. In 2006, Kazakhstan, Russia and Uzbekistan produced a combined 30.4% of worldwide uranium while supplying significant quantities of uranium into Western World markets. The Canadian uranium industry has in recent years been the leading world supplier, producing nearly 22.7% of the world supply.

Marketing Uranium

Denison markets its entire share of production from McClean Lake and Midwest jointly with AREVA Resources Canada Inc. (“ARC”) production from these properties through a joint marketing company, McClean Uranium Limited (“MUL”). MUL is incorporated in Saskatchewan and is owned 30% by Denison and 70% by ARC. Denison’s production from the White Mesa mill is marketed directly by Denison. Agreements with AREVA provide for production to be allocated first to market related contracts with any surplus to be apportioned evenly over the legacy contracts. The lower price, base-escalated legacy contracts expire by the end of 2008.

The sale of Denison’s uranium has traditionally been through long-term contracts and not on the spot market. These long-term, or “legacy” contracts have a variety of pricing methods, including fixed prices, base prices adjusted by inflation indices, changes in reference prices (spot price indicators or long-term contract reference prices) and annual price negotiations. Prices in the long-term market have normally been higher than those in the spot market at the time the contracts are entered into and are normally less volatile. However, when market prices are increasing rapidly, as has been the case over the last several years, prices received under some of the legacy contracts cannot match such market increases.

Delivery scheduling (or timing) under long-term contracts is at the discretion of the customer so may vary markedly from quarter to quarter.

Marketing of the White Mesa production, which is scheduled to begin in the second quarter of 2008, will concentrate on long-term contracts utilizing a variety of pricing mechanisms while retaining a portion of the production to be sold on the spot market to take advantage of opportunities in the current tight supply-demand situation.

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

The Vanadium Market

Vanadium is an essential alloying element for steels and titanium, and its chemical compounds are indispensable for many industrial and domestic products and processes. The principal uses for vanadium are: (i) carbon steels used for reinforcing bars; (ii) high strength, low alloy steels used in construction and pipelines; (iii) full alloy steels used in castings; (iv) tool steels used for high speed tools and wear resistant parts; (v) titanium alloys used for jet engine parts and air frames; and (vi) various chemicals used as catalysts.

Principal sources of vanadium are (i) titaniferous magnetites found in Russia, China, Australia and South Africa; (ii) sludges and fly ash from the refining and burning of U.S., Caribbean and Middle Eastern oils; and (iii) uranium co-product production from the Colorado Plateau. While produced and sold in a variety of ways, vanadium production figures and prices are typically reported in pounds of an intermediate product, vanadium pentoxide, or V 2 O 5 . The White Mesa mill is capable of producing three products, ammonium metavanadate (“AMV”) and vanadium pregnant liquor (“VPL”), both intermediate products, and vanadium pentoxide (“flake,” “black flake,” “tech flake” or “V 2 O 5 ”). The majority of sales are as V 2 O 5 , with AMV and VPL produced and sold on a request basis only.

In the United States, although vanadium is produced through processing petroleum residues, spent catalysts, utility ash, and vanadium bearing iron slag, the most significant source of production historically has been as a by-product of uranium production from ores in the Colorado Plateau District, accounting for more than half of historic U.S. production. Vanadium in these deposits typically occurs at an average ratio of five to six pounds of vanadium for every pound of uranium, and the financial benefit derived from the by-product sales have helped to make the mines in this area profitable in the past.

The market for vanadium has fluctuated greatly over the last 20 years. During the early 1980s, quoted prices were in the range of $3.00 per pound V 2 O 5 , but increased exports from China and Australia, coupled with the continued economic recession of the 1980s drove prices to as low as $1.30 per pound. Prices stabilized in the $2.00—$2.45 per pound range until perceived supply problems in 1988 caused by cancellation of contracts by China and rumours of South African production problems resulted in a price run-up to a high of nearly $12.00 per pound in February of 1989. This enticed new producers to construct additional capacity, and oversupply problems again depressed the price in the early 1990s to $2.00 per pound and below. Late in 1994, a reduction in supplies from Russia and China, coupled with concerns about the political climate in South Africa and a stronger steel market caused the price to climb to $4.50 per pound early in 1995. In the beginning of 1998, prices had climbed to a nine-year high of $7.00 caused by supply being unable to keep pace with record demand from steel and aerospace industries. However, during the second half of 1998, prices began to decline to $2.56 per pound by December 1998. This was due to sudden decreases in Far East steel production, along with suppliers from Russia and China selling available inventories at low prices in order to receive cash. Since that time, prices fell dramatically to a range of $1.20 to $1.50 per pound V 2 O 5 due in part to the difficult economic conditions being experienced throughout the Pacific Rim and new sources of supply coming into the market. In the third quarter of 2003, vanadium prices started to increase because of increased steel consumption and the shutdown of an Australian primary producer. This trend continued through 2004. In 2005, demand from China resulted in a significant price run-up culminating in all time highs of $23.00 to $27.00 per pound V 2 O 5 . Subsequently, prices declined to a range of $8.00 to $10.00 per pound V 2 O 5 , at the end of 2005, due to the ramp-up of Chinese vanadium production. Prices continued to decline during 2006 to the $7.00 to $8.00 range and have remained in this range throughout 2007. In early 2008, vanadium prices increased significantly to $14.00 to $15.00 per pound due to power supply issues in South Africa. South Africa is a major supply source of vanadium, representing approximately 39% of the world’s production.

World demand will continue to fluctuate in response to changes in steel production. However, the overall consumption is anticipated to increase as demand for stronger and lighter steels grows and the demand for titanium alloys for jet engine components increases with new aircraft orders throughout the world.

Marketing Vanadium

Prices for the products that are produced by the Company are generally based on weekly quotations published in Ryan’s Notes or Platt’s Metals Weekly. Historically, vanadium production from the White Mesa mill has been sold into the worldwide market both through traders, who take a 2% to 3% commission for their efforts and, to a lesser extent, through direct contacts with domestic converters and consumers. While priced in U.S. dollars per pound of V 2 O 5 , the product is typically sold by the container, which contains nominally 40,000 pounds of product packed in 55 gallon drums, each containing approximately 660 pounds of product.

RESULTS OF OPERATIONS

General

The Company recorded net income of $47,244,000 ($0.25 per share) for 2007 compared with a net loss of $16,998,000 ($0.18 per share) for 2006.

Revenues totaled $76,764,000 for 2007 compared with $9,722,000 for 2006. Expenses totaled $83,771,000 for 2007 compared with $33,816,000 for 2006. Net other income totaled $41,627,000 for 2007 compared with $7,399,000 for 2006.

Revenues

Uranium sales revenues for the fourth quarter were $34,173,000. Sales from U.S. production were 250,000 pounds U 3 O 8 at an average price of $89.84 per pound. Sales of Canadian production were 150,000 pounds U 3 O 8 at an average price of $74.37 per pound. Amortization of the fair value increment related to the DMI sales contracts totaled $906,000 for the quarter. Reported revenue is also impacted by the effect of foreign currency transactions.

Uranium sales revenues for the year were $65,125,000. Sales from U.S. production were 325,000 pounds U 3 O 8 at an average price of $99.11 per pound. Sales of Canadian production were 420,000 pounds U 3 O 8 at an average price of $74.91 per pound. Uranium sales revenue also includes amortization of the fair value increment related to long-term sales contracts from the acquisition of DMI in the amount of $2,418,000.

Uranium sales revenue in the 2006 period totaled $7,575,000 for the net sale of 109,400 pounds U 3 O 8 from Canadian production at an average sales price of $55.76 per pound and from amortization of the fair value increment related to the long-term sales contracts of DMI in the amount of $1,475,000. Revenue in 2006 represents only one month activity post acquisition of DMI.

Denison currently markets its uranium from the McClean Lake joint venture jointly with ARC. Denison’ share of current contracts sales volumes is set out in the table below:

Current Contracted Sales Volumes

Legacy Base Escalated 220 0 $20.00 to $26.00
Legacy Market Related 140 0 96% of Spot

Notes:

It is anticipated that the joint marketing of Canadian uranium production will cease at the end of 2008 except for the market related category above. Future long-term sales agreements for the Company’s uranium inventory and production are expected to be primarily under market related contracts with appropriate floor prices. In March 2007, one such contract was completed for the sale of 17% of the White Mesa mill production commencing in 2008 up to 6.5 million pounds with a minimum of 250,000 pounds in 2008 increasing to a minimum of 1 million pounds by 2011. The sales price is 95% of the published long-term price for the month prior to delivery with a floor price of $45.00. No other new sales contracts are in place at this time.

During 2007, the Company continued to receive alternate feed materials at the White Mesa mill. Alternate feed materials, usually classified as waste products by the processing facilities that generate these materials, contain uranium that can be recovered as an environmentally preferable alternative to direct disposal. The Company received a fee for a majority of its alternate feed materials once they are delivered to the mill. In addition to the recycling fees, the Company will retain any uranium recovered from these materials, which can be sold in subsequent periods, at which time the revenue from the sales will be recorded. Also during 2007, the Company continued to receive high-grade alternate feed materials under its existing contract with Cameco Corporation. The Company does not receive a recycling fee for these types of material; however, the Company is able to retain all of the proceeds received from the sale of the uranium produced.

During the year, the Company completed a processing campaign of alternate feed materials on which a processing fee is paid. Processing and by-product disposal revenue totaled $2,526,000 compared to $1,492,000 in 2006.

Revenue from the environmental services division was $4,723,000 compared to $221,000 in 2006. Revenue from the management contract with Uranium Participation Corporation was $4,390,000 compared to $430,000 in 2006. Both of these revenue sources were acquired in the DMI transaction that was effective December 1, 2006. Therefore 2006 revenues represent only one month.

Operating Expenses

Milling and Mining Expenses

The McClean Lake joint venture produced 738,000 pounds U 3 O 8 for the three months and 1,907,000 pounds U 3 O 8 for the year ended December 31, 2007. Denison’s 22.5% share of production totaled 166,000 and 429,000 pounds respectively.

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

The Midwest deposit is currently scheduled to commence production in mid-2011 and production is planned to be processed at a rate of about 8—9 million pounds per year. The processing of Cigar Lake ore, expected to ramp up to over 7.7 million pounds of mill output per year, was scheduled to commence in early 2008 until delayed by the flooding of the Cigar Lake mine in late 2006. The timing of commencement of production of Cigar Lake ore is in 2011 at the earliest. The McClean Lake mill expansion required to receive and process ore from Cigar Lake, which was funded by the Cigar Lake joint venture, is substantially complete. The McClean joint venture will have the benefit of the Cigar Lake expansion until it is utilized for processing Cigar Lake ore. Denison has no ownership interest in the Cigar Lake joint venture.

Production at the White Mesa mill from alternate feed milling was 254,000 pounds U 3 O 8 . The Company will continue to process alternate feed materials in the first quarter 2008

Sales Royalties and Capital Taxes

Sales royalties and capital taxes totaled $2,301,000 for the year compared with $420,000 in 2006. This difference is due to the inclusion of the operation of DMI for only one month in 2006. Denison pays a Saskatchewan basic uranium royalty of 4% of gross uranium sales after receiving the benefit of a 1% Saskatchewan resource credit. Denison also pays Saskatchewan capital taxes based on the greater of 3.3% of gross uranium sales and capital tax otherwise computed under the Saskatchewan Corporation Capital Tax Act. For uranium production after July 1, 2007, the factor applied to gross uranium sales for Saskatchewan capital tax purposes will be reduced to 3.1% with further reductions scheduled in 2008. The Saskatchewan government also imposes a tiered royalty which ranges from 6% to 15% of gross uranium sales after recovery of mill and mine capital allowances which approximate capital costs. Denison has sufficient mill and mine capital and expansion allowances available or anticipated to shelter it from the tiered royalty at current uranium prices for at least 2008.

Mineral Property Exploration

Denison is engaged in uranium exploration, as both operator and non-operator of joint ventures and as operator of its own properties in Canada, the U.S. and Mongolia. For the three months ended December 31, 2007 exploration expenditures totaled $4,049,000 and totaled $20,963,000 for the year ended December 31, 2007 as compared to $3,370,000 and $14,790,000 for the three and fifteen months ended December 31, 2006.

A majority of the exploration expenditures during the period were spent in the Athabasca Basin region of northern Saskatchewan. Denison is engaged in uranium exploration on advanced projects in this region of Canada as part of the ARC operated McClean and Midwest joint ventures. A significant discovery, termed the Midwest A deposit (formerly the Mae Zone) and located 3 km northeast of the proposed Midwest open pit, was drilled this past winter. Denison is also participating in a total of 33 other exploration projects concentrating in the productive southeast margin of the Athabasca Basin. Denison is operator of two mid-stage projects, the Moore Lake and the Wheeler River joint ventures, included in this portfolio. Denison’s share of exploration spending on its Canadian properties totaled $3,239,000 of which $3,036,000 was expensed in the statement of operations for the three months ended December 31, 2007 and totaled $17,445,000 of which $16,638,000 was expensed in the statement of operations for the year ended December 31, 2007.

Exploration expenditures of $1,000,000 for the three month period and $4,048,000 for the year ended December 31, 2007 were spent in Mongolia on the Company’s joint venture and 100% owned properties. The Company has a 70% interest in the Gurvan Saihan Joint Venture (“GSJV”) in Mongolia. The other parties to the joint venture are the Mongolian government as to 15% and Geologorazvedka, a Russian government entity, as to 15%. Additional expenditures for development of the GSJV’s Hairhan uranium deposits have also been incurred. Development work includes extensive resource delineation drilling, hydrological drilling, plant design and environmental studies.

The remaining expenditures of $13,000 for the three-month period and $277,000 for the year were spent on the Company’s other properties.

General and Administrative

General and administrative expenses were $3,871,000 for the three months and $13,469,000 for the year ended December 31, 2007 compared with $7,286,000 and $11,379,000 for the three and fifteen months ended December 31, 2006. The increase was primarily the result of the inclusion of Denison Mines Inc. (“DMI”) effective December 1, 2006, a ramping up of the Company’s operations, the acquisition and implementation of new information systems and an increase in public company expenses due to additional compliance costs. General and administrative expenses consist primarily of payroll and related expenses for personnel, contract and professional services and other overhead expenditures.

Other Income and Expenses

Other income (expense) totaled $4,284,000 for the three months and $41,627,000 for the year ended December 31, 2007 compared with $4,652,000 and $7,399,000 for the three and fifteen month periods ended December 31, 2006. The net other income in the quarter and for the year is primarily due to the disposition of portfolio investments.

Income Taxes

The Company has provided for a current tax expense of $3,141,000 and for a future tax recovery of $15,765,000. The future tax recovery results primarily from a decline in expected future income tax rates.

OUTLOOK FOR 2008

Mining and Production

Canada

Mining at the Sue E pit at McClean Lake in northern Saskatchewan is expected to be completed early in the second quarter of 2008. Stripping of the Sue B overburden was completed in 2007. Mining of the Sue B deposit, which contains approximately 1.4 million pounds U 3 O 8 , will follow completion of Sue E.

U 3 O 8 production at McClean Lake in 2008 is expected to be 3.2 million pounds of which Denison’s share is 720,000 pounds.

United States

Four mines are operating on the Colorado Plateau with production from the Sunday, Pandora, Topaz and West Sunday mines running at about 350 tons per day. At the Tony M mine within the Henry Mountains Complex, located in Utah, operational permits have been received and production from this mine is underway and will ramp up to 300 tons per day in the second quarter of 2008, eventually climbing to 450 tons per day by year end. Production from these mines is being hauled to Denison’s White Mesa mill and is currently being stockpiled. At December 31, 2007, a total of 85,000 tons had been shipped to the mill. The Company expects to have approximately 160,000 tons of material stockpiled before conventional ore production commences in May of 2008. Mine development work has begun at the Company’s Arizona 1 mine on the Arizona Strip located in northeastern Arizona. Ore production from this mine is anticipated by mid-2008.

The White Mesa mill refurbishment program is now scheduled to be completed by the end of April, 2008. The short delay is due to a number of factors including, abnormal snow fall, equipment deliveries, contractor availability and difficulties in completing the alternate feed processing. The $21 million program includes modifications and upgrading of the mill process equipment, upgrading the entire mill process control system, and relining of tailings cell 4A. Once relining of cell 4A is completed, the company will apply for an operating permit which is expected to be received by July 2008.

Due to the short delay in commencing the milling of conventional ore and scheduling of ore feeds, we now expect to produce 1.4 to 1.7 million pounds U 3 O 8 and 3 to 4 million pounds V 2 O 5 during 2008. The drop in uranium production is impacted primarily by the delay in processing on the Arizona 1 ore to late in the year. This has pushed uranium production from the fourth quarter 2008 to the first quarter of 2009.

Sales

The Company expects to sell 1.8—1.9 million pounds of U 3 O 8 in 2008 including 1.1—1.2 million pounds from U.S. production. It also anticipates selling 3 million pounds of vanadium. Vanadium prices are quite volatile but have recently risen to a level of $14 to $15 per pound V 2 O 5 from an average of $7.00 to $8.00 per pound in 2007. Most of Denison’s sales of uranium and vanadium from U.S. production will occur in the third and fourth quarters of the year.

Exploration

Athabasca Basin

In the Athabasca Basin, Denison is participating in 35 exploration projects, primarily located in the southeast part of the Basin and within trucking distance of all the three operating mills in the area. The physical properties of the basement rocks underlying the sandstone basin, not the sandstone, determine the economic potential of any property. Denison, together with a subsidiary of AREVA and Cameco Corporation, now control the majority of the highly favourable basement rocks in the prolific southeastern sector of the Basin.

Denison is participating in 14 drill programs during the current winter season in the Basin. Denison is operator on the Wheeler River, Park Creek, North Wedge, Bell Lake, and Moore Lake Joint Ventures. In addition, Denison is drilling on the 100% owned Bachman-Crawford Lakes, Jasper Lake, Stevenson River and Ahenakew projects. JNR Resources Inc. is operator of the Pendleton Lake JV, where four holes totalling 500 metres will be drilled, and the Lazy Edward Bay project where 3,500 metres in 20 holes are targeted. Near the McClean Mill, joint venture partner ARC is operator of the Midwest, Wolly and McClean projects, where 72 holes totalling 17,800 metres in aggregate are planned.

On Denison’s operated and non-operated projects, a total of approximately 34,000 metres of drilling is planned this winter. The Company’s projects in the Basin represent a good balance of grass roots, mid-stage, and development projects. Other than 11,600 metres dedicated to drilling advanced targets on the Midwest property, almost all holes are focussed on well prepared targets in high potential areas not yet at the development stage. Denison strives to achieve a budget total of 80% devoted to drilling.

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

In addition to these major drill campaigns, Denison is carrying out a number of different geophysical surveys to identify targets for future drill programs. Approximately 750 line kilometres of airborne geophysical surveys are being flown over two properties as an initial screening tool. Denison is also carrying out a large number of ground geophysical surveys on ten properties, where over 200 line kilometres of Fixed Loop or Moving Loop Time Domain EM surveys, 317 line kilometres of Horizontal Loop Electromagnetics and over 160 line kilometres of DC Resistivity surveys will be completed during the 2008 winter season. Over 675 line kilometres of ground magnetic surveys will also be carried out in conjunction with the above.

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

Southwest United States

Denison is planning on spending $2,000,000 on its 2008 U.S. exploration program. The program will be focussed on exploring near its existing operations on the Colorado Plateau. The program is projected to entail an estimated 149,000 feet (45,000 metres) of drilling.

Mongolia

In Mongolia, Denison is committing to a substantial increase in work compared to previous years. The work in 2007 was successful in confirming and enhancing the potential of the two advanced properties and several exploration projects while downgrading several reconnaissance projects.

Denison’s plans for 2008 involve over 85,000 metres of drilling. All drill and logging contracts have been signed and are in place for this work. On the GSJV Hairhan project, development drilling will be aimed at upgrading resources from inferred to indicated, and to test high potential areas for additional resources. Several basinal depressions (one over 200 kilometres long) will be evaluated. A major hydrological drilling program will also be undertaken at Hairhan in preparation for ISR pilot plant commercial testwork slated for 2009.

Zambia

Denison commenced field work in the last quarter of 2007, and is planning an intensive program of both reverse circulation and diamond drilling totalling 47,000 metres of drilling in support of its advanced work. A budget of over $20,000,000 is slated to upgrade resources, carry out a metallurgical pilot plant program and complete the feasibility study in support of taking an anticipated production decision in 2009. The Mutanga project has two deposits drill defined to date — Mutanga and Dibwe — where the drilling efforts are focussed on upgrading and expanding the resources of both deposits.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $19,680,000 at December 31, 2007 compared with $69,127,000 at December 31, 2006. The decrease of $49,447,000 was due primarily to the acquisition of OmegaCorp Limited (“OmegaCorp”) using net cash of $158,583,000 offset by net cash proceeds of $107,265,000 received from the issuance of common shares through private placements and exercise of warrants and stock options. In addition, the Company raised $52,870,000 from the sale of long-term investments and expended $59,578,000 for property, plant and equipment.

Net cash used in operating activities was $23,084,000 during 2007 compared with $27,494,000 during 2006. Net cash used in operating activities are comprised of net income for the period, adjusted for non-cash items and for changes in working capital items. Significant changes in working capital items during 2007 include increases of $28,443,000 (2006: $7,175,000) in trade and other receivables and $9,468,000 (2006: $4,414,000) in inventories. The increase in trade and other receivables during 2007 is primarily the result of uranium sales in December. The increase in inventories during 2007 consists primarily of the increase in ore in stockpile at December 31, 2007.

Net cash used in investing activities was $158,469,000 during 2007 compared with net cash provided of $45,752,000 during 2006. The decrease was due primarily to the acquisition of OmegaCorp using net cash of $158,583,000, expenditures on property, plant and equipment of $59,578,000 offset by proceeds from the sale of long-term investments of $52,870,000 and a decrease in notes receivable of $9,778,000.

During 2007, the Company completed two significant equity financings for total gross proceeds of $105,419,000 (Cdn$123,876,000). On January 9, 2007, the Company completed a private placement of 9,010,700 common shares at a price of Cdn$11.75 per share for gross proceeds of $89,847,000 (Cdn$105,876,000). On April 2, 2007, the Company completed a private placement of 1,104,295 flow-through common shares at a price of Cdn$16.30 per share for gross proceeds of $15,572,000 (Cdn$18,000,000) to fund eligible Canadian exploration expenditures. Net proceeds from these private placement financings totaled $102,151,000.

In total, these sources and uses of cash resulted in a net cash outflow of $49,447,000 during 2007 compared with a net cash inflow of $63,016,000 during 2006.

Subsequent to the year end, the Company put in place a Cdn$25,000,000 uncommitted secured revolving credit facility with the Bank of Nova Scotia. It is secured by the assets of Denison Mines Inc. Management is confident that the Company’s future cash flows and additional financing available to it will be sufficient to allow it to carry out its operational and development plans.

OFF-BALANCE SHEET ARRANGEMENTS

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

TRANSACTIONS WITH RELATED PARTIES

The Company is a party to a management services agreement with UPC. Under the terms of the agreement, the Company will receive the following fees from UPC: a) a commission of 1.5% of the gross value of any purchases or sales of U 3 O 8 and UF 6 completed at the request of the Board of Directors of UPC; b) a minimum annual management fee of Cdn$400,000 (plus reasonable out-of-pocket expenses) plus an additional fee of 0.3% per annum based upon UPC’s net asset value between Cdn$100,000,000 and Cdn$200,000,000 and 0.2% per annum based upon UPC’s net asset value in excess of Cdn$200,000,000; c) a fee of Cdn$200,000 upon the completion of each equity financing where proceeds to UPC exceed Cdn$20,000,000; d) a fee of Cdn$200,000 for each transaction or arrangement (other than the purchase or sale of U 3 O 8 and UF 6 ) of business where the gross value of such transaction exceeds Cdn$20,000,000 (“an initiative”); and e) an annual fee up to a maximum of Cdn$200,000, at the discretion of the Board of Directors of UPC, for on-going maintenance or work associated with an initiative. In accordance with the management services agreement, all uranium investments owned by UPC are held in accounts with conversion facilities in the name of Denison Mines Inc. as manager for and on behalf of UPC.

The Company was also a party to a temporary revolving credit facility agreement with UPC (not to exceed Cdn$15,000,000). The credit facility terminated on the earlier of repayment or May 10, 2007 and was collateralized by the uranium investments of UPC. Interest under the credit facility was based upon Canadian bank prime plus 1%. Standby fees also applied at a rate of 1% of the committed facility amount. As at December 31, 2006, UPC had drawn Cdn$11,000,000 under the facility. The temporary facility was fully repaid and cancelled on April 10, 2007.

In June 2007, the Company sold 75,000 pounds of U 3 O 8 to UPC at a price of $130.00 per pound for total consideration of $9,750,000.

CONTROLS AND PROCEDURES

| The Company carried out an evaluation, under the supervision and with the participation of
its management, including the Chief Executive Officer and Chief Financial Officer, of the
effectiveness of the design and operation of the Company’s “disclosure controls and
procedures” (as defined in the Exchange Act Rule 13a-15(e)) as of the end of the period
covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief
Financial Officer concluded that the Company’s disclosure controls and procedures are
effective. |
| --- |
| The Company’s management is responsible for establishing and maintaining an adequate system
of internal control over financial reporting. Management conducted an evaluation of the
effectiveness of internal control over financial reporting based on the Internal Control —
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission. Based on this evaluation, management concluded that the Company’s internal
control over financial reporting was effective as of December 31, 2007. Management’s
assessment of the effectiveness of the Company’s internal control over financial reporting
as of December 31, 2007 excluded the operations of OmegaCorp, which was acquired by the
Company effective August 1, 2007. OmegaCorp is a wholly-owned subsidiary of the Company.
OmegaCorp total assets represented approximately 23% of the book value of consolidated total
assets of the Company for the period ended December 31, 2007. Companies are allowed to
exclude acquisitions from their assessment of internal control over financial reporting
during the first year of an acquisition while integrating the acquired company under
guidelines established by the SEC. |
| There has not been any change in the Company’s internal control over financial reporting
that occurred during the Company’s fourth fiscal quarter of 2007 that has materially
affected, or is reasonably likely to materially affect, the Company’s internal control over
financial reporting. |

CRITICAL ACCOUNTING ESTIMATES

| The preparation of the Company’s consolidated financial statements in conformity with
generally accepted accounting principles in Canada requires management to make judgments
with respect to certain estimates and assumptions. These estimates and assumptions, based on
management’s best judgment, affect the reported amounts of certain assets and liabilities,
including disclosure of contingent liabilities. On an ongoing basis, management re-evaluates
its estimates and assumptions. Actual amounts, however, could differ significantly from
those based on such estimates and assumptions. |
| --- |
| Significant areas critical in understanding the judgments that are involved in the
preparation of the Company’s consolidated financial statements and the uncertainties
inherent within them include the following: |
| Depletion and Amortization of Property, Plant and Equipment |
| Depletion and amortization of property, plant and equipment used in production is calculated
on a straight line basis or a unit of production basis as appropriate. The unit of
production method allocates the cost of an asset to production cost based on current period production in proportion to total
anticipated production from the facility. Mining costs are amortized based on total
estimated uranium in the ore body. Mill facility costs to be amortized are reduced by
estimated residual values. In certain instances, residual values are established based upon
estimated toll milling fees to be received. If Denison’s estimated amounts to be received
from toll milling prove to be significantly different from estimates or its reserves and
resource estimates are different from actual (in the case where unit of production
amortization is used), there could be a material adjustment to the amounts of depreciation
and amortization to be recorded in the future. |

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

| Impairment of Long-Lived Assets |
| --- |
| The Company’s long-lived assets consist of plant and equipment, mineral properties, intangible
assets and goodwill. At the end of each accounting period, the Company reviews the carrying
value of its long-lived assets based on a number of factors. Capitalized mineral property
expenditures, these factors include analysis of net recoverable amounts, permitting
considerations and current economics. Should an impairment be determined, the Company would
write-down the recorded value of the long-lived asset to fair value. |
| Asset Retirement Obligations |
| Denison follows CICA Handbook section 3110, Asset Retirement Obligations, which requires that
the fair value of the full decommissioning cost of an asset be capitalized as part of property,
plant and equipment when the asset is initially constructed. In subsequent periods, Denison
then is required to recognize “interest” on the liability, to amortize the capital costs in a
rational and systematic manner, and to adjust the carrying value of the asset and liability for
changes in estimates of the amount or timing of underlying future cash flows. Denison has
accrued, in accordance with CICA Handbook Section 3110, its best estimate of the ongoing
reclamation liability in connection with the decommissioned Elliot Lake mine site and is
currently accruing its best estimate of its share of the cost to decommission its other mining
and milling properties. The costs of decommissioning are subject to inflation and to government
regulations, which are subject to change and often not known until mining is substantially
complete. A significant change in either may materially change the amount of the reclamation
liability accrual. |
| Stock-Based Compensation |
| Denison has recorded stock based compensation expense in accordance with the CICA handbook
section 3870, using the Black-Scholes option pricing model, based on its best estimate of the
expected life of the options, the expected volatility factor of the share price, a risk-free
rate of return and expected dividend yield. The use of different assumptions regarding these
factors could have a significant impact on the amount of stock-based compensation expense
charged to income over time. Changes in these estimates will only apply to future grants of
options and the amounts amortized over the vesting period of existing options should not change
as a result. |
| Retiree Benefit Obligation |
| Denison has assumed an obligation to pay certain and limited retiree medical and dental
benefits and life insurance as set out in a plan to a group of former employees. Denison has
made certain assumptions and will retain an actuary at least once every three years to estimate
the anticipated costs related to this benefit plan. The actual cost to Denison of this plan
will be influenced by changes in health care practices and actuarial factors. While the plan
contains certain limits, changes in assumptions could affect earnings. |

CHANGES IN ACCOUNTING POLICIES

| Effective December 1, 2006, the Company adopted the expensing of exploration expenditures on
mineral properties not sufficiently advanced to identify their development potential.
Previously, the Company had been capitalizing such exploration expenditures as incurred which
is permitted under Canadian GAAP, provided that these exploration expenditures have the
characteristics of property, plant and equipment and that capitalization is appropriate under
the circumstances. |
| --- |
| The primary purpose of this change in accounting policy is to align the accounting treatment of
exploration expenditures on mineral properties not sufficiently advanced to identify their
development potential, with those of the Company’s producing peers in the resource industry. |
| The Company has adopted this change in accounting policy on a retrospective basis with
restatement of the comparative periods presented. This change has also been applied to the
Company’s recognition of its investment in Fortress Minerals Corp. |
| The Company adopted the following new accounting standards effective January 1, 2007: |

| a) | CICA Handbook Section 1530: “Comprehensive Income” establishes standards for reporting
comprehensive income, defined as a change in value of net assets that is not due to owner
activities, by introducing a new requirement to temporarily present certain gains and losses
outside of net income. The impact of this new standard is discussed below in c); |
| --- | --- |
| b) | CICA Handbook Section 3251: “Equity” establishes standards for the presentation of equity
and changes in equity during the reporting period. The adoption of this new standard by the
Company did not have a material impact; |
| c) | CICA Handbook Section 3855: “Financial Instruments — Recognition and
Measurement“establishes standards for the recognition, classification and measurement of
financial instruments including the presentation of any resulting gains and losses. Assets
classified as available-for-sale securities have revaluation gains and losses included in other
comprehensive income (and not included in the income statement) until such time as the asset is
disposed of or incurs a decline in fair value that is other than temporary. At such time, any
gains or losses are then realized and reclassified to the income statement. At December 31,
2006, the Company had certain long-term investments that would be classified as
available-for-sale securities under this new standard, and any unrealized gains and losses
would be included in comprehensive income; and |
| d) | CICA Handbook Section 1506: Accounting Changes (“CICA 1506”) effective for fiscal years
beginning on or after January 1, 2007 establishes standards and new disclosure requirements for
the reporting of changes in accounting policies and estimates and the reporting of error
corrections. CICA 1506 clarifies that a change in accounting policy can be made only if it is a
requirement under Canadian GAAP or if it provides reliable and more relevant financial
statement information. Voluntary changes in accounting policies require retrospective
application of prior period financial statements, unless the retrospective effects of the
changes are impracticable to determine, in which case the retrospective application may be
limited to the assets and liabilities of the earliest period practicable, with a corresponding
adjustment made to opening retained earnings. |

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

The CICA issued the following accounting standards effective for the fiscal years beginning on or after October 1, 2007 and January 1, 2008:

| a) | Accounting Standards Section 3031 “Inventories” provides guidance on the determination of
cost and its subsequent recognition as an expense, including any write-down to net realizable
value. It also provides guidance on the cost formulas that are used to assign costs to
inventories and is effective for the fiscal years beginning on or after January 1, 2008. |
| --- | --- |
| b) | Accounting Standards Section 3862 “Financial Instruments — Disclosures” requires
disclosures in the financial statements that will enable users to evaluate: the significance of
financial instruments for the Company’s financial positions and performance; the nature and
extent of risks arising from financial instruments to which the Company is exposed during the
period and at the balance sheet date; and how the Company manages those risks. This accounting standard is effective for fiscal years beginning
on or after October 1, 2007. |

CONTRACTUAL OBLIGATIONS

| At December 31, 2007, the Company had a reclamation liability of $20,389,000 consisting of
$10,467,000 for U.S. mill and mine obligations, $8,319,000 for Elliot Lake and $1,603,000 for
the McClean Lake and Midwest joint ventures. |
| --- |
| In addition, the Company’s contractual obligations at December 31, 2007 are as follows: |

Total 1 Year 2—3 Years 4—5 Years After — 5 Years
Operating lease obligations $ 2,753,000 $ 767,000 $ 974,000 $ 643,000 $ 369,000

ENVIRONMENTAL RESPONSIBILITY

| The Company periodically reviews the anticipated costs of decommissioning and reclaiming its
mill and mine sites as part of its environmental planning process. Further, the Company
formally reviews the mill’s reclamation estimate annually with applicable regulatory
authorities. The mill and mine reclamation estimates at December 31, 2007 are $20,389,000
which are expected to be sufficient to cover the projected future costs for reclamation of
the mill and mine operations. However, there can be no assurance that the ultimate cost of
such reclamation obligations will not exceed the estimated liability contained in the
Company’s financial statements. |
| --- |
| The Company has posted bonds and letters of credit as security for these liabilities and has
deposited cash and equivalents as collateral against certain of these security items. At
December 31, 2007, the amount of these restricted investments collateralizing the Company’s
reclamation obligations was $15,849,000. |
| Although the White Mesa mill is designed as a facility that does not discharge to
groundwater, the Company has a Groundwater Discharge Permit (“GWDP”) with Utah Department of
Environmental Quality, which is required for all similar facilities in the State of Utah,
and specifically tailors the implementation of the State groundwater regulations to the Mill
site. The State of Utah requires that every operating uranium mill in the State have a GWDP,
regardless of whether or not the facility discharges to groundwater. The GWDP for the mill
was finalized and implemented during the second quarter of fiscal 2005. As requested by the
GWDP, the mill added over 40 additional monitoring parameters and fifteen additional
monitoring wells to its ground water monitoring program at the site. In addition, the State
and the Company are currently determining the compliance levels for all the monitoring
parameters. |
| As mentioned in previous reports, the Company has detected some chloroform contamination at
the mill site that appears to have resulted from the operation of a temporary laboratory
facility that was located at the site prior to and during the construction of the mill
facility, and from septic drain fields that were used for laboratory and sanitary wastes
prior to construction of the mill’s tailings cells. In April 2003, the Company commenced an
interim remedial program of pumping the chloroform-contaminated water from the groundwater
to the Mill’s tailings cells. This will enable the Company to begin clean up of the
contaminated areas and to take a further step towards resolution of this outstanding issue.
The investigations to date indicate that this contamination appears to be contained in a
manageable area. The scope and costs of remediation have yet to be fully determined but are
unlikely to be significant. |

RESEARCH AND DEVELOPMENT

The Company does not have a formal research and development program. Process development efforts expended in connection with processing alternate feeds are included as a cost of processing. Process development efforts expended in the evaluation of potential alternate feed materials that are not ultimately processed at the mill are included in mill overhead costs. The Company does not rely on patents or technological licenses in any significant way in the conduct of its business.

RISK FACTORS

There are a number of factors that could negatively affect Denison’s business and the value of Denison’s Common Shares, including the factors listed below. The following information pertains to the outlook and conditions currently known to Denison that could have a material impact on the financial condition of Denison. This information, by its nature, is not all inclusive. It is not a guarantee that other factors will not affect Denison in the future.

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

| Volatility and Sensitivity to Prices and Costs |
| --- |
| Because the majority of Denison’s revenues are derived from the sale of uranium and vanadium,
Denison’s net earnings and operating cash flow are closely related and sensitive to fluctuations in the long and short term
market price of U 3 O 8 and V 2 O 5 . Among other
factors, these prices also affect the value of Denison’s reserves and the market price of Denison’s
Common Shares. Historically, these prices have fluctuated and have been and will continue to be
affected by numerous factors beyond Denison’s control. |
| With respect to uranium, such factors include, among others: demand for nuclear power,
political and economic conditions in uranium producing and consuming countries, reprocessing of
used reactor fuel and the re-enrichment of depleted uranium tails, sales of excess civilian and
military inventories (including from the dismantling of nuclear weapons) by governments and
industry participants, uranium supply, including the supply from other secondary sources and
production levels and costs of production. With respect to vanadium, such factors include,
among others: demand for steel, political and economic conditions in vanadium producing and
consuming countries, world production levels and costs of production. |
| Although Denison employs various pricing mechanisms within its sales contracts to manage its
exposure to price fluctuations, there can be no assurance that such a program will be
successful. |
| Competition from Other Energy Sources and Public Acceptance of Nuclear Energy |
| Nuclear energy competes with other sources of energy, including oil, natural gas, coal and
hydro-electricity. These other energy sources are to some extent interchangeable with nuclear
energy, particularly over the longer term. Sustained lower prices of oil, natural gas, coal and
hydroelectricity may result in lower demand for uranium concentrates. Technical advancements in
renewable and other alternate forms of energy, such as wind and solar power, could make these
forms of energy more commercially viable and put additional pressure on the demand for uranium
concentrates. Furthermore, growth of the uranium and nuclear power industry will depend upon
continued and increased acceptance of nuclear technology as a means of generating electricity.
Because of unique political, technological and environmental factors that affect the nuclear
industry, the industry is subject to public opinion risks that could have an adverse impact on
the demand for nuclear power and increase the regulation of the nuclear power industry. |
| Uranium Industry Competition and International Trade Restrictions |
| The international uranium industry, including the supply of uranium concentrates, is
competitive. Denison markets uranium in direct competition with supplies available from a
relatively small number of western world uranium mining companies, from certain republics of
the former Soviet Union and the People’s Republic of China, from excess inventories, including
inventories made available from decommissioning of nuclear weapons, from reprocessed uranium
and plutonium, from used reactor fuel, and from the use of excess Russian
enrichment capacity to re-enrich depleted uranium tails held by European enrichers in the
form of UF 6 . The supply of uranium from Russia
and from certain republics of the former Soviet Union is, to some extent, impeded by a number
of international trade agreements and policies. These agreements and any similar future
agreements, governmental policies or trade restrictions are beyond the control of Denison and
may affect the supply of uranium available in the United States and Europe, which are the
largest markets for uranium in the world. |
| Competition for Properties |
| Significant competition exists for the limited supply of mineral lands available for
acquisition. Many participants in the mining business include large, established companies with
long operating histories. The Company may be at a disadvantage in acquiring new properties as
many mining companies have greater financial resources and more technical staff. Accordingly,
there can be no assurance that the Company will be able to compete
successfully to acquire new properties or that any such acquired assets would yield reserves or
result in commercial mining operations. |
| Replacement of Reserves and Resources |
| McClean Lake, Midwest, Arizona, Colorado Plateau and Henry Mountains reserves and resources are
currently Denison’s sources of uranium concentrates. Unless other reserves and resources are
discovered or extensions to existing ore bodies are found, Denison’s sources of production for
uranium concentrates will decrease over time as its current reserves and resources are
depleted. The McClean Lake, Midwest, Colorado Plateau and Arizona strip deposits are expected
to be produced by 2017, and the Henry Mountains’ deposits produced by 2020. There can be no
assurance that Denison’s future exploration, development and acquisition efforts will be
successful in replenishing its reserves. In addition, while Denison believes that the Midwest
deposit and certain of its US properties will be put into production, there can be no assurance
that they will be. |
| Due to the unique nature of uranium deposits, technical challenges exist involving groundwater,
rock properties, radiation protection and ore handling and transport. |

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

| Imprecision of Reserve and Resource Estimates |
| --- |
| Reserve and resource figures are estimates, and no assurances can be given that the
estimated levels of uranium and vanadium will be produced or that Denison will receive the
prices assumed in determining its reserves and resources. Such estimates are expressions of
judgment based on knowledge, mining experience, analysis of drilling results and industry
practices. Valid estimates made at a given time may significantly change when new
information becomes available. While Denison believes that the reserve and resource
estimates included are well established and reflect management’s best estimates, by their
nature, reserve and resource estimates are imprecise and depend, to a certain extent, upon
statistical inferences which may ultimately prove unreliable. Furthermore, market price
fluctuations, as well as increased capital or production costs or reduced recovery rates,
may render ore reserves and resources containing lower grades of mineralization uneconomic
and may ultimately result in a restatement of reserves and resources. The evaluation of
reserves or resources is always influenced by economic and technological factors, which may
change over time. |
| Decommissioning and Reclamation |
| As owner and operator of the White Mesa mill and numerous uranium and uranium/vanadium mines
located in the United States and as part owner of the McClean Lake mill, McClean Lake mines,
the Midwest uranium project and certain exploration properties, and for so long as the
Company remains an owner thereof, the Company is obligated to eventually reclaim or
participate in the reclamation of such properties. Most, but not all, of the Company’s
reclamation obligations are bonded, and cash and other assets of the Company have been
reserved to secure this bonded amount. Although the Company’s financial statements record a
liability for the asset retirement obligation, and the bonding requirements are generally
periodically reviewed by applicable regulatory authorities, there can be no assurance or
guarantee that the ultimate cost of such reclamation obligations will not exceed the
estimated liability contained on the Company’s financial statements. |
| In addition, effective January 20, 2001, the U.S. Bureau of Land Management (“BLM”)
implemented new Surface Management (3809) Regulations pertaining to mining operations
conducted on mining claims on public lands. The new 3809 regulations impose additional
requirements for permitting of mines on federal lands and may have some impact on the
closure and reclamation requirement for Company mines on public lands. If more stringent and
costly reclamation requirements are imposed as a result of the new 3809 rules, the amount of
reclamation bonds held by the Company and the reclamation liability recorded in the
Company’s financial statements may need to be increased. |
| Decommissioning plans for the Company’s properties have been filed with applicable
regulatory authorities. These regulatory authorities have accepted the decommissioning plans
in concept, not upon a detailed performance forecast, which has not yet been generated. As
Denison’s properties approach or go into decommissioning, further regulatory review of the
decommissioning plans may result in additional decommissioning requirements, associated
costs and the requirement to provide additional financial assurances. It is not possible to
predict what level of decommissioning and reclamation (and financial assurances relating
thereto) may be required in the future by regulatory authorities. |
| Technical Obsolescence |
| Requirements for Denison’s products and services may be affected by technological changes in
nuclear reactors, enrichment and used uranium fuel reprocessing. These technological changes
could reduce the demand for uranium or reduce the value of Denison’s environmental services
to potential customers. In addition, Denison’s competitors may adopt technological
advancements that give them an advantage over Denison. |
| Property Title Risk |
| The Company has investigated its rights to explore and exploit all of its material
properties and, to the best of its knowledge, those rights are in good standing. However, no
assurance can be given that such rights will not be revoked, or significantly altered, to
its detriment. There can also be no assurance that the Company’s rights will not be
challenged or impugned by third parties, including the local governments, and in Canada, by
First Nations and Metis. |
| The validity of unpatented mining claims on U.S. public lands is sometimes uncertain and may
be contested. Due to the extensive requirements and associated expense required to obtain
and maintain mining rights on U.S. public lands, the Company’s U.S. properties may be
subject to various uncertainties which are common to the industry, with the attendant risk
that its title may be defective. |
| Production Estimates |
| Denison prepares estimates of future production for particular operations. No assurance can
be given that production estimates will be achieved. Failure to achieve production estimates
could have an adverse impact on Denison’s future cash flows, earnings, results of operations
and financial condition. These production estimates are based on, among other things, the
following factors: the accuracy of reserve estimates; the accuracy of assumptions regarding
ground conditions and physical characteristics of ores, such as hardness and presence or
absence of particular metallurgical characteristics; and the accuracy of estimated rates and
costs of mining and processing. |

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

| Denison’s actual production may vary from estimates for a variety of reasons, including, among
others: actual ore mined varying from estimates of grade, tonnage, dilution and metallurgical
and other characteristics; short term operating factors relating to the ore reserves, such as
the need for sequential development of ore bodies and the processing of new or different ore
grades; risk and hazards associated with mining; natural phenomena, such as inclement weather
conditions, underground floods, earthquakes, pit wall failures and cave-ins; and unexpected
labour shortages or strikes. |
| --- |
| Mining and Insurance |
| Denison’s business is capital intensive and subject to a number of risks and hazards, including
environmental pollution, accidents or spills, industrial and transportation accidents, labour
disputes, changes in the regulatory environment, natural phenomena (such as inclement weather
conditions, earthquakes, pit wall failures and cave-ins) and encountering unusual or unexpected
geological conditions. Many of the foregoing risks and hazards could result in damage to, or
destruction of, Denison’s mineral properties or processing facilities, personal injury or
death, environmental damage, delays in or interruption of or cessation of production from
Denison’s mines or processing facilities or in its exploration or development activities, delay
in or inability to receive regulatory approvals to transport its uranium concentrates, or
costs, monetary losses and potential legal liability and adverse governmental action. In
addition, due to the radioactive nature of the materials handled in uranium mining and
processing, additional costs and risks are incurred by Denison on a regular and ongoing basis. |
| Although Denison maintains insurance to cover some of these risks and hazards in amounts it
believes to be reasonable, such insurance may not provide adequate coverage in the event of
certain circumstances. No assurance can be given that such insurance will continue to be
available or it will be available at economically feasible premiums or that it will provide
sufficient coverage for losses related to these or other risks and hazards. |
| Denison may be subject to liability or sustain loss for certain risks and hazards against which
it cannot insure or which it may reasonably elect not to insure because of the cost. This lack
of insurance coverage could result in material economic harm to Denison. |
| Dependence on Issuance of Licence Amendments and Renewals |
| The Company maintains regulatory licences in order to operate its mills at White Mesa and
McClean Lake, all of which are subject to renewal from time to time and are required in order
for the Company to operate in compliance with applicable laws and regulations. In addition,
depending on the Company’s business requirements, it may be necessary or desirable to seek
amendments to one or more of its licences from time to time. While the Company has been
successful in renewing its licences on a timely basis in the past and in obtaining such
amendments as have been necessary or desirable, there can be no assurance that such licence
renewals and amendments will be issued by applicable regulatory authorities on a timely basis
or at all in the future. |
| Nature of Exploration and Development |
| Exploration for and development of mineral properties is speculative, and involves significant
uncertainties and financial risks that even a combination of careful evaluation, experience and
knowledge may not eliminate. While the discovery of an ore body may result in substantial
rewards, few properties which are explored are commercially mineable or ultimately developed
into producing mines. Major expenses may be required to establish reserves by drilling,
constructing mining and processing facilities at a site, developing metallurgical processes and
extracting uranium from ore. It is impossible to ensure that the current exploration and
development programs of Denison will result in profitable commercial mining operations or that
current production at existing mining operations will be replaced with new reserves. |
| Denison’s ability to sustain or increase its present levels of uranium production is dependent
in part on the successful development of new ore bodies and/or expansion of existing mining
operations. The economic feasibility of development projects is based upon many factors,
including, among others: the accuracy of reserve estimates; metallurgical recoveries; capital
and operating costs of such projects; government regulations relating to prices, taxes,
royalties, infrastructure, land tenure, land use, importing and exporting, and environmental
protection; and uranium prices, which are historically cyclical. Development projects are also
subject to the successful completion of engineering studies, issuance of necessary governmental
permits and availability of adequate financing. |
| Development projects have no operating history upon which to base estimates of future cash
flow. Denison’s estimates of proven and probable reserves and cash operating costs are, to a
large extent, based upon detailed geological and engineering analysis. Denison also conducts
feasibility studies which derive estimates of capital and operating costs based upon many
factors, including, among others: anticipated tonnage and grades of ore to be mined and
processed; the configuration of the ore body; ground and mining conditions; expected recovery
rates of the uranium from the ore; and alternate mining methods. |
| It is possible that actual costs and economic returns of current and new mining operations may
differ materially from Denison’s best estimates. It is not unusual in the mining industry for
new mining operations to experience unexpected problems during the start-up phase, take much longer time than originally
anticipated to bring into a production phase and to require more capital than anticipated. |

MANAGEMENT’S DISCUSSION AND ANALYSIS Year Ended December 31, 2007

| Governmental Regulation and Policy Risks |
| --- |
| The Company’s mining and milling operations and exploration activities, as well as the
transportation and handling of the products produced, are subject to extensive regulation by
state, provincial and federal governments. Such regulations relate to production,
development, exploration, exports, imports, taxes and royalties, labour standards,
occupational health, waste disposal, protection and remediation of the environment, mine
decommissioning and reclamation, mine safety, toxic substances, transportation safety and
emergency response, and other matters. Compliance with such laws and regulations has
increased the costs of exploring, drilling, developing, constructing, operating and closing
Denison’s mines and processing facilities. It is possible that, in the future, the costs,
delays and other effects associated with such laws and regulations may impact Denison’s
decision as to whether to operate existing mines, or, with respect to exploration and
development properties, whether to proceed with exploration or development, or that such
laws and regulations may result in Denison incurring significant costs to remediate or
decommission properties that do not comply with applicable environmental standards at such
time. Denison expends significant financial and managerial resources to comply with such
laws and regulations. Denison anticipates it will have to continue to do so as the historic
trend toward stricter government regulation may continue. Because legal requirements are
frequently changing and subject to interpretation, Denison is unable to predict the ultimate
cost of compliance with these requirements or their effect on operations. Furthermore,
future changes in governments, regulations and policies, such as those affecting Denison’s
mining operations and uranium transport could materially and adversely affect Denison’s
results of operations and financial condition in a particular period or its long term
business prospects. |
| Failure to comply with applicable laws, regulations and permitting requirements may result
in enforcement actions. These actions may result in orders issued by regulatory or judicial
authorities causing operations to cease or be curtailed, and may include corrective measures
requiring capital expenditures, installation of additional equipment or remedial actions.
Companies engaged in uranium exploration operations may be required to compensate others who
suffer loss or damage by reason of such activities and may have civil or criminal fines or
penalties imposed for violations of applicable laws or regulations. |
| Worldwide demand for uranium is directly tied to the demand for electricity produced by the
nuclear power industry, which is also subject to extensive government regulation and
policies. The development of mines and related facilities is contingent upon governmental
approvals that are complex and time consuming to obtain and which, depending upon the
location of the project, involve multiple governmental agencies. The duration and success of
such approvals are subject to many variables outside Denison’s control. Any significant
delays in obtaining or renewing such permits or licences in the future could have a material
adverse effect on Denison. In addition, the international marketing of uranium is subject to
governmental policies and certain trade restrictions, such as those imposed by the
suspension agreements between the United States and Russia and the agreement between the
United States and Russia related to the supply of Russian HEU into the United States. Changes in these policies and restrictions may
adversely impact Denison’s business. |
| Operations in Foreign Jurisdictions |
| The Company owns uranium properties directly and through joint venture interests and is
undertaking a uranium exploration program in Mongolia and a development program in Zambia.
As with any foreign operation, these international properties and interests are subject to
certain risks, such as the possibility of adverse political and economic developments,
foreign currency controls and fluctuations, as well as risks of war and civil disturbances.
Other events may limit or disrupt activities on these properties, restrict the movement of
funds, result in a deprivation of contract rights or the taking of property or an interest
therein by nationalization or expropriation without fair compensation, increases in taxation
or the placing of limits on repatriations of earnings. No assurance can be given that
current policies of Mongolia or Zambia or the political situations within these countries
will not change so as to adversely affect the value or continued viability of the Company’s
interest in these assets. |
| In addition, the Company may become involved in a dispute with respect to one of its foreign
operations and may become subject to the exclusive jurisdiction of a foreign court or may
find that it is not successful in subjecting foreign persons to the jurisdiction of the
courts in Canada. The Company may also be precluded from enforcing its rights with respect
to a government entity because of the doctrine of sovereign immunity. |
| Environmental, Health and Safety Risks |
| Denison has expended significant financial and managerial resources to comply with
environmental protection laws, regulations and permitting requirements in each jurisdiction
where it operates, and anticipates that it will be required to continue to do so in the
future as the historical trend toward stricter environmental regulation may continue. The
uranium industry is subject to, not only the worker health, safety and environmental risks
associated with all mining businesses, including potential liabilities to third parties for
environmental damage, but also to additional risks uniquely associated with uranium mining
and processing. The possibility of more stringent regulations exists in the areas of worker
health and safety, the disposition of wastes, the decommissioning and reclamation of mining
and processing sites, and other environmental matters each of which could have a material
adverse effect on the costs or the viability of a particular project. |

| Denison’s facilities operate under various operating and environmental permits, licences and
approvals that contain conditions that must be met, and Denison’s right to continue operating
its facilities is, in a number of instances, dependent upon compliance with such conditions.
Failure to meet any such condition could have a material adverse effect on Denison’s financial
condition or results of operations. |
| --- |
| Although the Company believes its operations are in compliance, in all material respects, with
all relevant permits, licences and regulations involving worker health and safety as well as
the environment, there can be no assurance regarding continued compliance or ability of the
Company to meet stricter environmental regulation, which may also require the expenditure of
significant additional financial and managerial resources. |
| Aboriginal Title and Consultation Issues |
| First Nations and Métis title claims as well as related consultation issues may impact
Denison’s ability and that of its joint venture partners to pursue exploration, development and
mining at its Saskatchewan properties.
Pursuant to historical treaties, First Nations bands in Northern Saskatchewan ceded title to
most traditional lands but continue to assert title to the minerals within the lands. Managing
relations with the local native bands is a matter of paramount importance to Denison. There may
be no assurance however that title claims as well as related consultation issues will not arise
on or with respect to the Company’s properties. |
| Accounting Policies |
| The accounting policies and methods employed by the Company determine how it reports its
financial condition and results of operations, and they may require management to make
judgements or rely on assumptions about matters that are inherently uncertain. The Company’s
results of operations are reported using policies and methods in accordance with Canadian GAAP.
Management of Denison exercises judgement in applying accounting methods to ensure that, while
GAAP compliant, they reflect the most appropriate manner in which to record the Company’s
financial condition and operating results. In certain instances, Canadian GAAP allows
accounting policies and methods to be selected from two or more alternatives, any of which
might be reasonable but may result in Denison reporting materially different amounts.
Management regularly re-evaluates its assumptions but the choice of method or policy employed
may have a significant impact on the actual values reported. |
| Credit Risk |
| Denison’s sales of uranium and vanadium products and its environmental services expose Denison
to the risk of non-payment. Denison manages this risk by monitoring the credit worthiness of
its customers and requiring pre-payment or other forms of payment security from customers with
an unacceptable level of credit risk. |
| Although Denison seeks to manage its credit risk exposure, there can be no assurance that
Denison will be successful and that some of Denison’s customers will fail to pay for the
uranium or vanadium purchased or the environmental services provided. |
| Currency Fluctuations |
| Most of Denison’s revenue is denominated in U.S. dollars; however, its operating costs are
incurred in the currencies of the United States, Canada, Mongolia and Zambia. Consequently,
changes in the relative value of the different currencies affect Denison’s earnings and cash
flows. |
| Capital Intensive Industry; Uncertainty of Funding |
| The exploration and development of mineral properties and the ongoing operation of mines
requires a substantial amount of capital and may depend on Denison’s ability to obtain
financing through joint ventures, debt financing, equity financing or other means. Volatile
uranium markets, a claim against the Company, a significant disruption to the Company’s
business or operations or other factors may make it difficult to secure financing necessary to
the expansion of mining activities or to take advantage of opportunities for acquisitions.
There is no assurance that the Company will be successful in obtaining required financing as
and when needed on acceptable terms. |
| Dependence on Key Personnel |
| Denison’s success will largely depend on the efforts and abilities of certain senior officers
and key employees. Certain of these individuals have significant experience in the uranium
industry. The number of individuals with significant experience in this industry is small.
While Denison does not foresee any reason why such officers and key employees will not remain
with Denison, if for any reason they do not, Denison could be adversely affected. Denison has
not purchased key man life insurance for any of these individuals. |
| Internal Controls |
| Internal controls over financial reporting are procedures designed to provide reasonable
assurance that transactions are properly authorized, assets are safeguarded against
unauthorized or improper use, and transactions are properly recorded and reported. A control
system, no matter how well designed and operated, can provide only reasonable, not absolute,
assurance with respect to the reliability of financial reporting and financial statement
preparation. |

| Conflicts of Interest |
| --- |
| Some of the directors of Denison are also directors of other companies that are similarly
engaged in the business of acquiring, exploring and developing natural resource properties.
Such associations may give rise to conflicts of interest from time to time. In particular,
one of the consequences will be that corporate opportunities presented to a director of
Denison may be offered to another company or companies with which the director is
associated, and may not be presented or made available to Denison. The directors of Denison
are required by law to act honestly and in good faith with a view to the best interests of
Denison, to disclose any interest which they may have in any project or opportunity of
Denison, and to abstain from voting on such matter. Conflicts of interest that arise will be
subject to and governed by the procedures prescribed by the OBCA. |
| Reliance on ARC as Operator |
| As ARC is the operator and majority owner of the McClean Lake and Midwest properties in
Saskatchewan, Canada, Denison is and will be, to a certain extent, dependent on ARC for the
nature and timing of activities related to these properties and may be unable to direct or
control such activities. |
| Labour Relations |
| Both the McClean Lake mill and the Midwest properties employ unionized workers who work
under collective agreements. ARC, as the operator of both of these projects, is responsible
for all dealings with unionized employees. ARC may not be successful in its attempts to
renegotiate the collective agreements, which may impact mill and mining operations. Any
lengthy work stoppages may have a material adverse impact on the Company’s future cash
flows, earnings, results of operations and financial condition. |
| Indemnities |
| As part of a reorganization in 2004, DMI acquired from Denison Energy all of Denison
Energy’s mining and environmental services assets and agreed to assume all debts,
liabilities and obligations relating to such assets before the date of the reorganization.
In addition, DMI agreed to provide certain indemnities in favour of Denison Energy for
certain claims and losses relating to matters with respect to Denison Energy’s mining
business prior to the date of the arrangement, to breaches by DMI of certain of its
agreements, covenants, representations and warranties in the agreements governing such
reorganization, and to damages caused by breaches by DMI of its representations and
warranties in certain agreements related to such arrangement. Denison cannot predict the
outcome or the ultimate impact of any legal or regulatory proceeding against Denison or
affecting the business of Denison and cannot predict the potential liabilities associated
with the indemnities provided in favour of Denison Energy. Consequently, there can be no
assurance that the legal or regulatory proceedings referred to in this MD&A or any such
proceedings that may arise in the future will be resolved without a material adverse effect
on the business, financial condition, results of operation or cash flows of Denison. |

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. Management conducted an evaluation of the effectiveness of internal control over financial reporting based on the Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as at December 31, 2007. Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as at December 31, 2007 excluded the operations of OmegaCorp, which was acquired by the Company effective August 1, 2007. OmegaCorp is a wholly-owned subsidiary of the Company. OmegaCorp total assets represented approximately 23% of the book value of consolidated total assets of the Company for the period ended December 31, 2007.

CHANGES TO INTERNAL CONTROL OVER FINANCIAL REPORTING

There has not been any change in the Company’s internal control over financial reporting that occurred during the Company’s fourth fiscal quarter of 2007 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

INDEPENDENT AUDITORS’ REPORT

| To the Shareholders of Denison Mines Corp., |
| --- |
| We have completed an integrated audit of the consolidated financial statements and internal
control over financial reporting of Denison Mines Corp. as at December 31, 2007 and audits of
its 2006 and 2005 consolidated financial statements. Our opinions, based on our audits, are
presented below. |
| Consolidated Financial Statements |
| We have audited the accompanying consolidated balance sheets of Denison Mines Corp. as at
December 31, 2007 and 2006, and the related consolidated statements of operations and deficit,
comprehensive income and cash flows for the year ended December 31, 2007, the fifteen-month
period ended December 31, 2006 and the year ended September 30, 2005. These financial
statements are the responsibility of the Company’s management. Our responsibility is to express
an opinion on these financial statements based on our audits. |
| We conducted our audit of the Company’s financial statements as at December 31, 2007 and for
the year then ended in accordance with Canadian generally accepted auditing standards and the
standards of the Public Company Accounting Oversight Board (United States). We conducted our
audits of the Company’s financial statements as at December 31, 2006 and for the fifteen-month
period ended December 31, 2006 and the year ended September 30, 2005 in accordance with
Canadian generally accepted auditing standards. Those standards require that we plan and
perform an audit to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit of financial statements includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. A financial
statement audit also includes assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion. |
| In our opinion, the consolidated financial statements referred to above present fairly, in all
material respects, the financial position of the Company as at December 31, 2007 and 2006 and
the results of its operations and its cash flows for the year ended December 31, 2007, the
fifteen-month period ended December 31, 2006 and the year ended September 30, 2005 in
accordance with Canadian generally accepted accounting principles. |
| Internal Control over Financial Reporting |
| We have also audited Denison Mines Corp.’s internal control over financial reporting as at
December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The
Company’s management is responsible for maintaining effective internal control over financial
reporting and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Management’s Report on Internal Control over Financial
Reporting. Our responsibility is to express an opinion on the effectiveness of the Company’s
internal control over financial reporting based on our audit. |
| We conducted our audit of internal control over financial reporting in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether
effective internal control over financial reporting was maintained in all material respects. An
audit of internal control over financial reporting includes obtaining an understanding of
internal control over financial reporting, assessing the risk that a material weakness exists,
testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we consider necessary in the
circumstances. We believe that our audit provides a reasonable basis for our opinion. |
| A company’s internal control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting
principles. A company’s internal control over financial reporting includes those policies and
procedures that (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company;
(ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance
with authorizations of management and directors of the company; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial
statements. |
| Because of its inherent limitations, internal control over financial reporting may not prevent
or detect misstatements. Also, projections of any evaluation of effectiveness to future periods
are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate. |
| As described in Management’s Report on Internal Controls over Financial Reporting, management
has excluded OmegaCorp from its assessment of internal control over financial reporting as at
December 31, 2007 because it was acquired by the Company effective August 1, 2007. We have also
excluded OmegaCorp from our audit of internal control over financial reporting. OmegaCorp is a
wholly-owned subsidiary whose total assets represent 23% of the related consolidated financial
statement amounts as at and for the year ended December 31, 2007. |
| In our opinion, the Company maintained, in all material respects, effective internal control
over financial reporting as at December 31, 2007 based on criteria established in Internal
Control — Integrated Framework issued by the COSO. |

| Comments by Auditors on Canada — US Reporting Differences |
| --- |
| In the United States, reporting standards for auditors require the addition of an explanatory
paragraph (following the opinion paragraph) when there is a change in accounting principles that
has a material effect on the comparability of the Company’s financial statements, such as the
changes described in Note 3 to these consolidated financial statements. Our report to the
shareholders dated March 18, 2008 is expressed in accordance with Canadian reporting standards
which do not require a reference to such a change in accounting principles in the Auditors’ report
when the change is properly accounted for and adequately disclosed in the financial statements. |

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Expressed in U.S. dollars, unless otherwise noted)

1. NATURE OF OPERATIONS
Denison Mines Corp. is incorporated under the Business Corporations Act (Ontario) (“OBCA”).
Denison Mines Corp. and its subsidiary companies and joint ventures (collectively, the
“Company”) are engaged in uranium mining and related activities, including acquisition,
exploration and development of uranium bearing properties, extraction, processing, selling and
reclamation. The environmental services division of the Company provides mine decommissioning
and decommissioned site monitoring services for third parties.
The Company has a 100% interest in the White Mesa mill located in Utah, United States and a
22.5% interest in the McClean Lake mill located in the Athabasca Basin of Saskatchewan, Canada.
The Company has interests in a number of nearby mines at both locations, as well as interests
in development and exploration projects located in Canada, the United States, Mongolia and
Zambia, some of which are operated through joint ventures and joint arrangements. Uranium, the
Company’s primary product, is produced in the form of uranium oxide
concentrates (“U 3 O 8 ”) 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, or
V 2 O 5 . The Company is also in the business of recycling
uranium bearing waste materials, referred to as “alternate feed materials”.
Denison Mines Inc. (“DMI”), a subsidiary of the Company is the manager of Uranium Participation
Corporation (“UPC”), a publicly-listed investment holding company formed to invest substantially all of its assets in
U 3 O 8 and uranium hexafluoride (“UF 6 ”). The Company has no
ownership interest in UPC but receives various fees for management services and commissions
from the purchase and sale of
U 3 O 8 and UF 6 by UPC.
In August 2006, the Company changed its fiscal year end from September 30 to December 31 to
align its reporting periods with that of its peers in the uranium industry. The Company had
elected to use a 15-month period ending December 31, 2006 for its audited consolidated
financial statements as permitted under Canadian securities regulation. References to “2007”,
“2006” and “2005” refer to the year ended December 31, 2007, the 15-month period ended December
31, 2006 and the year ended September 30, 2005 respectively.
2. SUMMARY OF SIGNIFICANT MINING INTERESTS AND ACCOUNTING POLICIES
Basis of Presentation
These consolidated financial statements have been prepared by management in U.S. dollars,
unless otherwise stated, in accordance with generally accepted accounting principles in Canada
(“Canadian GAAP”). All adjustments considered necessary by management for fair presentation
have been included in these financial statements. Differences between Canadian GAAP and those
generally accepted accounting principles and practices in the United States (“U.S. GAAP”) that
would have a significant impact on these financial statements are disclosed in Note 28.
Significant Mining Interests
The following table sets forth the Company’s ownership of its significant mining interests that
have projects at the development stage within them as at December 31, 2007:
Location Ownership — Interest
Through majority owned subsidiaries
Arizona Strip USA 100.00 %
Henry Mountains USA 100.00 %
Colorado Plateau USA 100.00 %
Sunday Mine USA 100.00 %
Gurvan Saihan Joint Venture Mongolia 70.00 %
Mutanga Zambia 100.00 %
As interests in unincorporated joint ventures, or jointly controlled assets
McClean Lake Canada 22.50 %
Midwest Canada 25.17 %

| Significant Accounting Policies |
| --- |
| The principal accounting policies and practices under Canadian GAAP followed by the Company
in the preparation of these financial statements are summarized below: |
| a) Principles of Consolidation |
| These consolidated financial statements include the accounts of Denison Mines Corp., its
subsidiaries and its share of assets, liabilities, revenues and expenses of
jointly-controlled companies and unincorporated ventures proportionate to the Company’s
percentage ownership or participating interest. All significant intercompany balances and
transactions have been eliminated on consolidation. |

48 Denison Mines Corp. Annual Report 2007

Folio /Folio

PAGEBREAK

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

| The companies and ventures controlled by Denison Mines Corp. are consolidated using the full
consolidation method. Control is defined as the direct or indirect power to govern a company’s
financial and operating policies in order to benefit from its activities. |
| --- |
| The companies and ventures jointly controlled by Denison Mines Corp. are consolidated using the
proportionate consolidation method. Joint control is deemed to exist when agreements exist that
require that material changes to the operating, investing and financing policies of such
company or venture be approved by a percentage of the participating interest sufficiently high
enough to prevent any one participant from exercising unilateral control. |
| The companies and ventures in which Denison Mines Corp. exercises significant influence over
financial policy and management (“associates”) are accounted for using the equity method. In
determining whether significant influence exists, the Company evaluates a number of criteria
including the percentage of voting interest held, and representation on the board of directors
or in senior management. |
| Variable Interest Entities (“VIEs”) (which include, but are not limited to, special purpose
entities, trusts, partnerships and other legal structures) are consolidated by the Company if
it is the primary beneficiary who will absorb the majority of the entities expected losses and
/ or expected residual returns in accordance with the guidance in Canadian Institute of
Chartered Accountants (“CICA”) Accounting Guideline (“AcG”) 15, “Consolidation of Variable
Interest Entities”. |
| b) Use of Estimates |

| The presentation of consolidated financial statements in conformity with Canadian GAAP 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
determination of economic lives, recoverability of and reclamation obligations for property,
plant and equipment and the evaluation of post-employment benefits, future income taxes,
contingent liabilities and stock-based compensation. |
| --- |
| c) Foreign Currency Translation |

| As of December 1, 2006, the Company’s currency of measurement for its Canadian operations,
including those acquired under the business combination with Denison Mines Inc., is the
Canadian dollar. As the Company’s reporting currency is the U.S. dollar, the Company applies
the current rate method for translation of the Company’s net investment in its Canadian
operations. Assets and liabilities denominated in currencies other than the U.S. dollar are
translated at the exchange rate in effect at the balance sheet date. Revenues and expenses
denominated in currencies other than the U.S. dollar are translated at the average rate in
effect during the period. Translation gains and losses are recorded in other comprehensive
income which will be recognized in the results of operations upon the substantial disposition,
impairment, liquidation or closure of the investment that gave rise to such amounts. |
| --- |
| Prior to December 1, 2006, the Company’s primary currency of measurement and reporting was the
U.S. dollar. Monetary assets and liabilities denominated in currencies other than the U.S.
dollar were translated at the exchange rate in effect at the balance sheet date. Non-monetary
assets and liabilities denominated in currencies other than the U.S. dollar were translated at
the exchange rate in effect at the transaction date. Revenues and expenses denominated in
currencies other than the U.S. dollar were translated at the average rate in effect during the
period, with the exception of depreciation and amortization which were translated at historical
rates. Translation gains and losses were recorded in the results of operations for the period. |
| d) Income Taxes |

| Income taxes are accounted for using the liability method of accounting for future income
taxes. Under this method, current income taxes are recognized for the estimated income taxes
payable for the current period. Future 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 future income tax assets such as tax
losses available for carry forward are limited to the amount that is “more likely than not” to
be realized. |
| --- |
| e) 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. In accordance with Emerging
Issues Committee (“EIC”) Abstract No. 146: Flow-Through Shares applicable for flow-through
financings initiated after March 19, 2004, the foregone tax benefits to the Company are
recognized by reducing the proceeds received from these financings by the tax effects of the
renunciation to the subscribers at the time of renunciation by the Company. |
| --- |
| f) Cash and Equivalents |

| Cash and equivalents consist of cash on deposit and highly-liquid, short-term money market
instruments which, on acquisition, have terms to maturity of three months or less. Cash and
equivalents which are subject to restrictions that prevent its use for current purposes are
classified as restricted investments. |
| --- |
| g) Inventories |

Expenditures, including depreciation, depletion and amortization of assets, incurred in the mining and processing activities that will result in 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 cost 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.

Denison Mines Corp. Annual Report 2007 49

Folio /Folio

PAGEBREAK

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

| 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 (including overburden removal and in-pit stripping costs) 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 as well as production costs incurred to convert the ore into a saleable product.
Conversion costs typically include labour, chemical reagents and certain 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. |
| Mine and mill supplies are valued at the lower of average cost and replacement cost. |
| h) Investments |

| Portfolio investments over which the Company does not exercise significant influence are
accounted for as available for sale securities. |
| --- |
| Investments in affiliates over which the Company exercises significant influence are
accounted for using the equity method, whereby the investment is initially recorded at cost
and adjusted to recognize the Company’s share of earnings or losses, reduced by dividends
and distributions received. |
| i) Property, Plant and Equipment |
| Plant and Equipment |

| Property, plant and equipment are recorded at acquisition or production cost and carried net
of depreciation. 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. |
| --- |
| Mineral Property Acquisition, Exploration and Development Costs |

| Mineral property costs include acquisition costs relating to acquired mineral use rights and
are capitalized. |
| --- |
| Expenditures are expensed as incurred on mineral properties not sufficiently advanced as to
identify their development potential. At the point in time that a mineral property is
considered to be sufficiently advanced and development potential is identified, all further
expenditures for the current year and subsequent years are capitalized as incurred. These
costs will include further exploration, 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. |
| Impairment of Long-Lived Assets |

| The Company applies CICA Handbook Section 3063: Impairment of Long-Lived Assets which
provides standards for the recognition, measurement and disclosure of impairment of
long-lived assets including property, plant and equipment. |
| --- |
| Long-lived assets are assessed by management for impairment whenever events or changes in
circumstances indicate that the related carrying amounts may not be recoverable. The amount
of the impairment loss is determined as the excess of the carrying value of the asset over
its fair value and is charged to the results of operations. Fair value represents future
undiscounted cash flows from an area of interest, including estimates of selling price and
costs to develop and extract the mining assets. |
| j) Asset Retirement Obligations |

| The Company applies CICA Handbook Section 3110: Asset Retirement Obligations which provides
standards for the recognition, measurement and disclosure of liabilities for asset
retirement obligations and the associated asset retirement costs. |
| --- |
| Asset retirement obligations, any statutory, contractual or other legal obligation related
to the retirement of tangible long-lived assets, are recognized when such obligations are
incurred, if a reasonable estimate of fair value can be determined. These obligations are
measured initially at fair value 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. |
| 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. |

PAGEBREAK

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

| k) Goodwill and Other Intangibles |
| --- |
| Business combinations are accounted for under the purchase method of accounting whereby
acquired assets and liabilities are recorded at fair value as of the date of acquisition. The
excess of the purchase price over the fair value is recorded as goodwill. The Company evaluates
the carrying amount of goodwill at least annually to determine whether events or changes in
circumstances indicate that such carrying amount may no longer be recoverable. Any impairment
as determined in accordance with CICA Handbook Section 3062: Goodwill and Other Intangible
Assets is charged to operations. |
| l) Post-Employment Benefits |

| 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 on immediate pension 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. |
| --- |
| m) Fair Values |

| The carrying amounts for cash and equivalents, trade and other receivables, notes receivable
and accounts payable and accrued liabilities on the balance sheet approximate fair value
because of the limited term of these instruments. The fair value of other long-term liabilities
approximates book value unless otherwise disclosed. Fair value estimates are made at the
balance sheet date, based on relevant market data. |
| --- |
| n) Revenue Recognition |

| Revenue from the sale of uranium concentrate to customers is recognized when title to the
product passes to the customer and delivery is effected by book transfer. |
| --- |
| 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 decommissioning 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 earned from UPC are recognized as earned on a monthly basis. Commission revenue
earned on acquisition or sale of U 3 O 8 and UF 6 on behalf of UPC is recognized on the date
when title passes to UPC. |

Revenues are recognized only to the extent they are reasonably considered to be collectible.
o) Stock-Based Compensation

| Effective October 1, 2004, the Company retrospectively adopted, without restatement, the
amended standards of CICA Handbook Section 3870: Stock-Based Compensation and Other Stock-Based
Payments (“Section 3870”) which established standards for the recognition, measurement and
disclosure of stock-based compensation and other stock-based payments made in exchange for
goods and services. |
| --- |
| Section 3870 requires a fair value-based method of accounting for stock options granted to
employees, including directors, and to non-employees. The fair value of stock options granted
is recognized on a straight-line basis 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. |
| p) Earnings (Loss) per Share |

| Basic earnings (loss) per share is computed by dividing net income (loss) for the period by the
weighted-average number of common shares outstanding for the period. The Company follows the
“treasury stock” method in the calculation of diluted earnings per share. Under this method,
the calculation of diluted earnings per share assumes that the proceeds to be received from the
exercise of “in the money” stock options and warrants are applied to repurchase common shares
at the average market price for the period. The calculation of diluted loss per share does not
make this assumption as the result would be anti-dilutive. |
| --- |
| q) Financial Instruments — Recognition and Measurement |

CICA Handbook Section 3855: Financial Instruments — Recognition and Measurement establishes standards for the recognition, classification and measurement of financial instruments including the presentation of any resulting gains and losses. Assets classified as available-for-sale securities will have revaluation gains and losses included in other comprehensive income (and not included in the income statement) until such time as the asset is disposed of or incurs a decline in fair value that is other than temporary. At such time, any gains or losses will then be realized and reclassified to the income statement.

Recent Pronouncements
The CICA issued the following accounting standards effective for the fiscal years beginning
on or after October 1, 2007 and January 1, 2008:

| a) | Accounting Standards Section 3031 “Inventories” provides guidance on the determination of
cost and its subsequent recognition as an expense, including any write-down to net
realizable value. It also provides guidance on the cost formulas that are used to assign
costs to inventories and is effective for the fiscal years beginning on or after January 1,
2008. |
| --- | --- |
| b) | Accounting Standards Section 3862 “Financial Instruments — Disclosures” requires
disclosures in the financial statements that will enable users to evaluate: the significance
of financial instruments for the company’s financial positions and performance; the nature
and extent of risks arising from financial instruments to which the company is exposed
during the period and at the balance sheet date; and how the company manages those risks.
This accounting standard is effective for fiscal years beginning on or after October 1,
2007. |
| c) | General Accounting Section 1535 “Capital Disclosures” requires the disclosure of both
qualitative and quantitative information that enable users to evaluate the company’s
objectives, policies and processes for managing capital. |
| d) | Effective January 1, 2009, the Company will adopt Section 3064 “Goodwill and Intangible
Assets” which establishes revised standards for recognition, measurement, presentation and
disclosure of goodwill and intangible assets. Concurrent with the introduction of this
standard, the CICA withdrew EIC 27 “Revenues and expenses during the pre-operating period”.
As a result of the withdrawal of EIC 27, the Company will no longer be able to defer costs
and revenues incurred prior to commercial production at new mine operations. |

Comparative Numbers
Certain classifications of the comparative figures have been changed to conform to those
used in the current period.
3.
The Company adopted the following new accounting standards effective January 1, 2007:

| a) | CICA Handbook Section 1530: “Comprehensive Income” establishes standards for reporting
comprehensive income, defined as a change in value of net assets that is not due to owner
activities, by introducing a new requirement to temporarily present certain gains and losses
outside of net income. The impact of this new standard is discussed below in c); |
| --- | --- |
| b) | CICA Handbook Section 3251: “Equity” establishes standards for the presentation of equity
and changes in equity during the reporting period. The adoption of this new standard by the
Company did not have a material impact; |
| c) | CICA Handbook Section 3855: “Financial Instruments — Recognition and Measurement”
establishes standards for the recognition, classification and measurement of financial
instruments including the presentation of any resulting gains and losses. Assets classified
as available-for-sale securities have revaluation gains and losses included in other
comprehensive income (and not included in the income statement) until such time as the asset
is disposed of or incurs a decline in fair value that is other than temporary. At such time,
any gains or losses are then realized and reclassified to the income statement. At December
31, 2006, the Company had certain long-term investments that would be classified as
available-for-sale securities under this new standard, and any unrealized gains and losses
would be included in comprehensive income; and |
| d) | CICA Handbook Section 1506: Accounting Changes (“CICA 1506”) effective for fiscal years
beginning on or after January 1, 2007 establishes standards and new disclosure requirements
for the reporting of changes in accounting policies and estimates and the reporting of error
corrections. CICA 1506 clarifies that a change in accounting policy can be made only if it
is a requirement under Canadian GAAP or if it provides reliable and more relevant financial statement information. Voluntary changes in
accounting policies require retrospective application of prior period financial statements,
unless the retrospective effects of the changes are impracticable to determine, in which
case the retrospective application may be limited to the assets and liabilities of the
earliest period practicable, with a corresponding adjustment made to opening retained
earnings. |

| Exploration Expenditures |
| --- |
| In 2006, the Company adopted the policy of expensing exploration expenditures on mineral
properties not sufficiently advanced to identify their development potential. Previously,
the Company had been capitalizing such exploration expenditures as incurred which is
permitted under Canadian GAAP, provided that these exploration expenditures have the
characteristics of property, plant and equipment and that capitalization is appropriate
under the circumstances. |
| The primary purpose of this change in accounting policy is to align the accounting
treatment of exploration expenditures on mineral properties not sufficiently advanced to
identify their development potential, with those of the Company’s producing peers in the
resource industry. |
| The Company has adopted this change in accounting policy on a retrospective basis with
restatement of the comparative periods presented. This change has also been applied to the
Company’s recognition of its investment in Fortress Minerals Corp. |

| Stock-Based Compensation |
| --- |
| Effective October 1, 2004, the Company adopted the amended standards of CICA Handbook Section
3870 which establishes standards for the recognition, measurement and disclosure of stock-based
compensation and other stock-based payments made in exchange for goods and services. It
requires a fair value-based method of accounting for stock options granted to employees,
including directors, and to non-employees. Prior to October 1, 2004, the application of the
fair value-method of accounting was limited to stock options granted to non-employees. The
intrinsic value-based method of accounting was applied to stock options granted to employees
which did not result in additional stock-based compensation expense as the exercise price was
equal to the market price on the grant date. Pro forma disclosure of net income (loss) and
earnings (loss) per share had the fair value-method been applied to stock options granted to
employees was required. |
| The Company has adopted the amendments to CICA Handbook Section 3870 on a retrospective basis
without restatement of periods prior to October 1, 2004. As a result, a cumulative adjustment
of $774,000 to opening deficit effective October 1, 2004 has been reported separately on the
consolidated statements of deficit. This adjustment represents the fair value of stock options
granted to employees of $738,000 during 2004 and $36,000 during 2003. |

  1. ACQUISITIONS

| Acquisition of OmegaCorp Limited (“Omega”) |
| --- |
| In 2007, the Company acquired 154,250,060 common shares of Omega and initiated compulsory
acquisition proceedings for the remaining shares that it did not yet own. The cost of this
investment, which was settled in cash, was $167,204,000. The Company has determined that it
exercises control over Omega and is using the full consolidation method to account for this
investment effective August 1, 2007. Prior to this date, the investment was being accounted for
using the fair value method. |

Accounts payable and accrued liabilities 947
Future income tax liability 52,022
Total liabilities 52,969
Net assets purchased $ 167,204

| Omega’s assets and liabilities were measured at their individual fair values as of August 1, 2007.
The majority of the fair value has been allocated to the Mutanga project mineral property resources
included in the property, plant and equipment value above. In arriving at these preliminary fair
values, management has made assumptions, estimates and assessments at the time these financial
statements were prepared. The future income tax liability as a result of these fair value
adjustments has been estimated based on the income tax rates that management believes are most
applicable to the operations acquired. In Zambia, the income tax rate used in the estimate was 25%. |
| --- |
| Subsequent to the 2007 year-end, the Zambian government proposed enactment of legislation which
would increase the income tax rate for mining companies from 25% to 30%. The Company is still
evaluating the impact of this proposed legislative change. |

| Acquisition of Denison Mines Inc. (“DMI”) |
| --- |
| Effective December 1, 2006, International Uranium Corporation (“IUC”) completed the acquisition of
Denison Mines Inc. (“DMI”) pursuant to the terms of an arrangement agreement dated September 18,
2006, as amended and restated on October 16, 2006 (the “Arrangement”). Under the Arrangement, IUC
and DMI entered into a business combination by way of a plan of arrangement whereby IUC acquired
all of the issued and outstanding shares of DMI in a share exchange at a ratio of 2.88 common
shares of IUC for each common share of DMI. Immediately thereafter, the pre-Arrangement
shareholders of IUC and DMI each owned 50.2% and 49.8%, respectively, of the Company with
177,648,226 common shares issued and outstanding, excluding the effects of outstanding stock
options and share purchase warrants. |
| Concurrent with the Arrangement, the Company changed its name from International Uranium
Corporation to Denison Mines Corp. (“DMC”). |
| DMI was formed by arrangement under the OBCA and, prior to the Arrangement, its common shares were
publicly traded on the TSX under the symbol DEN. DMI is engaged in uranium mining and related
activities and its assets include a 22.5% interest in the McClean Lake mill and nearby mines and an
environmental services division which provides mine decommissioning and decommissioned site
monitoring services for third parties. |
| The purchase price calculation for the Arrangement is summarized below (in thousands, except for
per share amounts): |

DMI common shares outstanding
Exchange ratio 2.88
Common shares of IUC issued to DMI shareholders 87,991
Fair value per share of each IUC common share issued, in CDN$ $ 5.74
Fair value of common shares issued by the Company, in CDN$ $ 505,069
Canadian/U.S. dollar exchange rate 1.1449
Fair value of common shares issued by the Company $ 441,147
Fair value of DMI share purchase warrants assumed by the Company 11,744
Fair value of DMI stock options assumed by the Company 25,635

| The fair value per share of each IUC common share represents the weighted-average closing price
of the two days before, day of and two days after the day the Arrangement was announced on
September 18, 2006. The calculation of the fair value of the share purchase warrants assumed by
the Company to replace those of DMI was based on the weighted-average closing price of each
warrant series for the two days before, day of and two days after the day the Arrangement was
announced on September 18, 2006. The calculation of the fair value of stock options assumed by
the Company to replace those of DMI was determined using the Black-Scholes option pricing
model. Each DMI stock option and warrant will provide the holder the right to acquire a common
share of the Company when presented for exercise adjusted by the exchange ratio above. |
| --- |
| The fair value of the share purchase warrants assumed by the Company to replace those of DMI
totaled $11,744,000 (CDN$13,445,000) and was based on a fair value of $1.23 (CDN$1.40) per
share. As at December 1, 2006, DMI had outstanding share purchase warrants to purchase
1,099,051 common shares of DMI exercisable at CDN$15.00 per share (the “November 2004” series)
and outstanding share purchase warrants to purchase 2,225,000 common shares of DMI exercisable
at CDN$30.00 per share (the “March 2006” series). Each warrant assumed is exercisable for 2.88
shares of the Company (see Note 16). |
| The fair value of the stock options assumed by the Company to replace those of DMI totaled
$25,635,000 (CDN$29,349,000). The calculation of this fair value of $6.31 (CDN$7.22) per share
was estimated as of December 1, 2006 using the Black-Scholes option pricing model with the
following weighted-average assumptions: risk-free interest rate of 3.90%, expected stock price
volatility of 50%, expected life of 3.75 to 4.93 years and expected dividend yield of Nil. As
at December 1, 2006, DMI had outstanding fully-vested stock options to purchase 1,411,000
common shares of DMI exercisable at a weighted-average price of CDN$11.15 per share with
various expiry dates to October 4, 2016. |
| The allocation of the purchase price is based on management’s estimate of the fair values after
giving effect to the Arrangement as summarized below: |

DMI
Fair Value
(in thousands) December 1, 2006
Cash and equivalents $ 63,634
Other current assets 25,067
Long-term investments 7,596
Property, plant and equipment

Mineral properties 325,618
Restricted investments 1,990

UPC management contract 6,463
Goodwill 105,915
Total assets 606,417
Current liabilities
Account payable and accruals 6,234
Fair value of sales and toll milling contracts 6,201
Provision for post-employment benefits 3,692
Reclamation and remediation obligations 7,888
Other long-term liabilities
Fair value of sales and toll milling contracts 9,520
Other 33
Future income tax liability 90,909
Total liabilities 124,477
Net assets purchased $ 481,940

| The Arrangement has been accounted for under the purchase method with IUC as the acquirer for
accounting purposes. In making this determination, management considered the relative shareholdings
of the combined company, the premium paid by IUC to acquire DMI and the composition of the board of
directors and the executive management team. |
| --- |
| DMI’s assets and liabilities were measured at their individual fair values as of December 1, 2006.
In arriving at these fair values, management has made assumptions, estimates and assessments at the
time these financial statements were prepared. The company engaged independent valuators to assist
in the determination of the fair values of the significant assets and liabilities acquired. The
future income tax liability as a result of these fair value adjustments has been estimated based on
a statutory income tax rate of 31%. |
| In 2007, the Company adjusted the fair value of the UPC management contract. The estimated useful
life of the contract was reduced to 8 years from 13 years and the associated discounted cash flow
stream was decreased by CDN$4,600,000. The fair value adjustment (net of future tax effects) has
been reclassified to goodwill. The intangible asset is being amortized over its estimated life of 8
years (see Notes 9 and 10). |

from April 30, 2005 to September 30, 2005, the fifteen month period ended December 31, 2006
and the six month period ended June 30, 2007, the equity method was used. The equity method
was discontinued subsequent to June 30, 2007 and the appropriate portion of the cumulative
equity accounting adjustments were derecognized at the time of the common share sales and
included in the gain referred to above. |
| In 2006, the Company recognized a dilution gain of $7,167,000 offset by a loss in equity of
$4,003,000 associated with its investment in Fortress. |

c) Wolly — in October 2004, the Company entered into an option agreement with its joint venture partners to earn a 22.5% ownership interest in the Wolly project by funding CDN$5,000,000 in exploration expenditures over the next six years. As at December 31, 2007, the Company has incurred a total of CDN$2,560,000 towards this option and has earned a 6.5% ownership interest in the project under the phase-in ownership provisions of the agreement.

United States
During 2007 and 2006, the Company commenced mining activities through the re-opening of some of
its U.S. mines in Colorado, Utah and Arizona which had been shut down since 1999.
In March 2007, the Company acquired certain uranium deposits located in the Arizona Strip
district in northeastern Arizona for cash consideration of $5,500,000 (excluding deal costs)
plus a 1% royalty.
In January 2007, the Company completed a mineral property acquisition in the Henry Mountains
district by issuing an additional 103,000 shares at a value of $947,000 (see Note 15).
Mongolia
The Company has a 70% interest in and is the managing partner of the Gurvan Saihan Joint
Venture in Mongolia. The results of the Gurvan Saihan Joint Venture have been included in these
financial statements on a consolidated basis since the Company exercises control.
During 2006, the Company recorded a write-down of mineral property acquisition costs totaling
$204,000 relating to certain of its Mongolian uranium properties due to exploration program
results that did not warrant further work. Many of these properties were grass roots
exploration prospects licensed in 2004 on the basis of favorable geology and radiometric
anomalies. The properties were aggressively explored in 2005 and 2006.
During 2005, the Company recorded a write-down of mineral property acquisition costs of
$1,761,000 relating to a decision by Fortress not to pursue its option on the Shiveen Gol
Property, a precious/base metal property located in Mongolia.
Zambia
In August 2007, the Company acquired certain uranium deposits located in Zambia in conjunction
with its purchase of Omega. The deposits, which are part of the Mutanga project, have been
assigned a fair value of $208,088,000 (see Note 4).

| 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. In 2007, the Company
deposited an additional CDN$552,000 into the Reclamation Trust Fund. |

UPC Management Contract
The UPC management contract is associated with the acquisition of DMI (see Note 4). The initial
fair value of $10,481,000 was determined using a discounted cash flow approach after taking
into account an appropriate discount rate. In 2007, the Company adjusted the fair value of the
contract by $4,279,000 and adjusted the estimated useful life of the contract to 8 years. The
contract is being amortized over its 8 year estimated useful life. The fair value adjustment
(net of future tax effects) has been reclassified to goodwill.
Urizon Technology Licenses
The Company has a 50% interest in a joint venture with Nuclear Fuel Services, Inc. (“NFS”) (the
“Urizon” joint venture) to pursue an alternate feed program for the White Mesa mill. NFS
contributed its technology license to the joint venture while the Company contributed
$1,500,000 in cash together with its technology license. The accounts of Urizon have been
included in the Company’s consolidated financial statements on a proportionate consolidation
basis. The joint venture has no cash flows arising from investing or financing activities.
This Urizon technology license is being amortized over an estimated useful life of 12 years and
represents the Company’s 50% interest in Urizon’s technology licenses.

| The Company’s acquisition of DMI was accounted for using the purchase method. The excess of the
purchase price over the fair value of the net assets acquired has been recorded as goodwill. Under
GAAP, goodwill is not amortized and is tested annually for impairment. The goodwill has been
allocated to the Company’s Canadian mining segment. |

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Site Restoration: U.S. Mill and Mines

The decommissioning and reclamation of the White Mesa mill and U.S. mines are subject to legal and regulatory requirements. Estimates of the costs of reclamation are reviewed periodically by the applicable regulatory authorities. The current estimate for the White Mesa mill and U.S. mines are $8,809,000 and $1,658,000, respectively. The above accrual represents the company’s best estimate of the present value of future reclamation costs, discounted at 7.5%. The undiscounted amount of estimated future reclamation costs is $14,801,000.

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 7.5%. The undiscounted amount of estimated future reclamation costs is $25,372,000.

Spending on restoration activities at the Elliot Lake site are funded from monies in the Elliot Lake Reclamation Trust fund (Note 8).

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 7.5%. The undiscounted amount of estimated future reclamation costs is $17,245,000.

Under the Mineral Industry Environmental Protection Regulations (1996), the Company is required to provide its pro-rata share of financial assurances to the province. The Company has provided irrevocable standby letters of credit, from a chartered bank, in favour of Saskatchewan Environment totalling CDN$8,064,000.

Revenue Concentration
The Company’s business is such that, at any given time, it sells its uranium and vanadium
concentrates to and enters into process milling arrangements and other services with a
relatively small number of customers. During 2007, three customers accounted for approximately
91% of total revenues. During 2006, two customers accounted for approximately 79% of total
revenues. During 2005, a process milling customer accounted for approximately 33% of total
revenues.
22. RELATED PARTY TRANSACTIONS
Uranium Participation Corporation
The Company is a party to a management services agreement with UPC. Under the terms of the
agreement, the Company will receive the
following fees from UPC: a) a commission of 1.5% of the gross value of any purchases or
sales of
U 3 O 8 and UF 6 completed at the request
of the Board of Directors of UPC; b) a minimum annual management fee of CDN$400,000 (plus
reasonable out-of-pocket expenses) plus an additional fee of 0.3% per annum based upon UPC’s
net asset value between CDN$100,000,000 and CDN$200,000,000 and 0.2% per annum based upon UPC’s
net asset value in excess of CDN$200,000,000; c) a fee of CDN$200,000 upon the completion of
each equity financing where proceeds to UPC exceed CDN$20,000,000; d) a fee of CDN$200,000 for
each transaction or arrangement (other than the purchase
or sale of
U 3 O 8 and UF 6 ) of business where the gross
value of such transaction exceeds CDN$20,000,000 (“an initiative”); and e) an annual
fee up to a maximum of CDN$200,000, at the discretion of the Board of Directors of UPC, for
on-going maintenance or work associated with an initiative.
In accordance with the management services agreement, all uranium investments owned by UPC are
held in accounts with conversion facilities in the name of Denison Mines Inc. as manager for
and on behalf of UPC.
The Company was also a party to a temporary revolving credit facility agreement with UPC (not
to exceed CDN$15,000,000). The credit facility terminated on the earlier of repayment or May
10, 2007 and was collateralized by the uranium investments of UPC. Interest under the credit
facility was based upon Canadian bank prime plus 1%. Standby fees also applied at a rate of 1%
of the committed facility amount. As at December 31, 2006, UPC had drawn CDN$11,000,000 under
the facility. The temporary credit facility was fully repaid and cancelled on April 10, 2007.
In June 2007, the Company sold 75,000 pounds of
U 3 O 8 to UPC at a
price of $130.00 per pound for total consideration of $9,750,000.
The following transactions were incurred with UPC for the periods noted:

| Credit Risk |
| Financial instruments that potentially subject the Company to a concentration of credit risk
consist of cash and cash equivalents, accounts receivable, amounts due from joint ventures,
and restricted fixed income securities. The Company deposits cash and cash equivalents with
financial institutions it believes to be creditworthy, principally in money market funds,
which may at certain times, exceed federally insured levels. The Company’s restricted
investments consist of investments in U.S. government bonds, commercial paper and high-grade
corporate bonds with maturities extending beyond 90 days. The Company performs ongoing
credit evaluation of its customers’ financial condition and, in most cases, requires no
collateral from its customers. The Company will maintain an allowance for doubtful accounts
receivable in those cases where the expected collectability of accounts receivable is in
question. |
| Fair Values |
| The fair values of cash and cash equivalents, trade and other receivables and accounts
payable and accrued liabilities approximate their carrying values because of the short-term
nature of these instruments. |
| The fair values of the Company’s restricted investments in cash and cash equivalents, U.S.
government bonds, commercial paper and corporate bonds approximate carrying values. |

| 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 has agreed to indemnify Calfrac Well Services against any future liabilities it may
incur related to the assets or liabilities transferred to the Company on March 8, 2004. |
| Performance Bonds and Letters of Credit |
| In conjunction with various contracts, reclamation and other performance obligations, the
Company may be required to issue performance bonds and letters of credit as security to
creditors to guarantee the Company’s performance. Any potential payments which might become due
under these items would be related to the Company’s non-performance under the applicable
contract. As at December 31, 2007, the Company had outstanding bonds and letters of credit of
$22,966,000 of which $15,849,000 was collateralized by restricted cash (see Note 8). |
| Others |
| The Company has committed to payments under various operating leases. The future minimum lease
payments are as follows: |

27. SUBSEQUENT EVENTS
In March, 2008, the Company put in place a CDN$25,000,000 uncommitted secured revolving credit
facility with the Bank of Nova Scotia. It is secured by the assets of Denison Mines Inc.
28. MATERIAL DIFFERENCES BETWEEN CANADIAN AND U.S. GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
The consolidated financial statements have been prepared in accordance with Canadian GAAP which
differ in certain material respects from those principles and practices that the Company would
have followed had its consolidated financial statements been prepared in accordance with U.S.
GAAP. Material differences between financial statement items under Canadian GAAP and the
amounts determined under U.S. GAAP are as follows:
a) Cash and Equivalents
U.S. GAAP requires that funds raised through the issuance of flow-through shares be shown as
restricted cash and not be considered to be a component of cash and cash equivalents. In
addition, the restricted cash would be excluded from cash and cash equivalents in the statement
of cash flows and shown as a financing activity. At December 31, 2007 $7,862,000 of funds
raised from the issue of flow-through shares remained (December 31, 2006: nil).
b) Long-Term Investments
In 2005 and 2006, Canadian GAAP required portfolio investments to be carried at the lower of
cost and estimated fair market value. In 2007, Canadian GAAP harmonized its accounting standard
with that of the U.S. Under U.S. GAAP, a difference existed in 2005 and 2006 since portfolio
investments that are classified as
available-for-sale securities are recorded at fair value and unrealized gains or losses are
excluded from earnings and recorded as other comprehensive income, a separate component of
shareholders’ equity.
c) Plant and Equipment
Under Canadian GAAP, the Company’s surplus assets held for resale were depreciated to an amount
less than net realizable value. Under U.S. GAAP, assets held for resale are recorded at the
lower of cost or net realizable value and are not depreciated.
d) Mineral Properties
Under Canadian GAAP, the Company expenses exploration and development expenditures on mineral
properties not sufficiently advanced to identify their development potential. At the point in
time that management feels that the mineral property has sufficient development potential,
costs are accumulated and recorded as mineral property assets. Under U.S. GAAP, all mine
project related costs incurred before a commercially mineable deposit is established are
expensed as incurred. The U.S defines a commercially mineable deposit as one with proven and
probable reserves and a bankable feasibility study.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

| e) Joint Ventures |
| --- |
| Under Canadian GAAP, investments in jointly-controlled entities are permitted to be accounted
for using the proportionate consolidation method. Under U.S. GAAP, investments in
jointly-controlled entities are accounted for using the equity method. Although there are
material differences between these accounting methods, the Company relies on an accommodation
of the United States Securities and Exchange Commission (“SEC”) permitting the Company to
exclude the disclosure of such differences which affect only the display and classification of
financial statement items excluding shareholders’ equity and net income. |
| f) Goodwill |
| Under Canadian GAAP, the Company’s formation in 1997 through an amalgamation of IUC with
Thornbury Capital Corporation (“Thornbury”) has been accounted for as an acquisition of
Thornbury resulting in the recording of goodwill. Under U.S. GAAP, the transaction has been
accounted for as a recapitalization whereby the net monetary assets of Thornbury would be
recorded at fair value, except that no goodwill or other intangibles would be recorded. The
goodwill recorded under Canadian GAAP has been subsequently written off. As a result, the
deficit and share capital of the Company are both reduced under U.S. GAAP. |
| g) Liabilities |
| Under U.S. GAAP, the sale of flow-through shares results in a liability being recognized for
the excess of the purchase price paid by the investors over the fair value of common shares
without the flow-through feature. The fair value of the shares is recorded as equity. When the
tax deductibility of the expenditures is renounced, the liability is reversed and a future
income tax liability is recorded for the amount of the benefits renounced to third parties and
an income tax expense is recognized. Under Canadian GAAP, an adjustment to share capital is
recorded for recognized future tax liabilities related to the renunciation of flow-through
share expenditures. |
| h) Dilution Gains |
| Under Canadian GAAP, gains on dilution of interests in a subsidiary or equity interest are
recognized in income in the period in which they occur. Under U.S. GAAP, the gain on dilution
is not recognized if it results from the sale of securities by a company in the exploration
stage and instead is accounted for as a capital transaction. |
| i) Foreign Currency Translation |
| In 2006, Canadian GAAP required unrealized translation gains and losses as a result of
translating self-sustaining operations under the current rate method to be accumulated in a
cumulative translation adjustment account as a separate component of shareholders’ equity. In
2007, Canadian GAAP harmonized its standards
with that of the U.S. Under U.S. GAAP, these unrealized translation gains and losses are shown
as an adjustment to other comprehensive income. |

Impact of New Accounting Pronouncements

| a) | FASB Statement No. 157: Fair Value Measurements (“SFAS 157”) effective for 2008
establishes a framework for measurement of fair value under generally accepted accounting
principles and expands the disclosure requirements covering fair value measurement. In
February 2008, the FASB amended SFAS 157 to exclude leasing transactions and to delay the
effective date by one year for non financial assets and liabilities that are recognized or
disclosed at fair value in the financial statements on a non recurring basis. The Company is
in the process of determining the effect, if any, the adoption of SFAS 157 will have on its
financial statements. |
| --- | --- |
| b) | FASB Statement No. 159: The Fair Value Option for Financial Assets and Financial
Liabilities — Including an Amendment of FASB
Statement No. 115 (“SFAS 159”) allows an entity to choose to measure many financial
instruments and certain other items at fair value, with subsequent changes in fair value
being recognized as unrealized gains or losses in the income statement in the period in
which the change occurred. The Statement is effective for fiscal years beginning on or
after November 15, 2007. The Company does not expect a material affect on its financial
results as a result of adopting this standard. |
| c) | FASB Statement No. 160: Noncontrolling Interests in Consolidated Financial Statements —
an amendment of ARB No. 51 (“SFAS 160”) and FASB Statement No. 141R: Business Combinations
(“SFAS 141R”) are both effective for annual periods beginning after December 15, 2008. SFAS
160 requires that third party ownership interests in subsidiaries be presented separately in
the equity section of the balance sheet. In addition, the income attributable to the
noncontrolling interest will now be included in consolidated net income and will be deducted
separately at the bottom of the income statement. SFAS 141R requires that most identifiable
assets, liabilities (including obligations for contingent consideration), noncontrolling
interests and goodwill be recorded at “full fair value”. Also, for step acquisitions, the
acquirer
will be required to re-measure its noncontrolling equity investment in the acquiree at fair
value as of the date control is obtained and recognize any gain or loss in income. The
Company has yet to complete its evaluation of the impact of these pronouncements. |
