MANAGEMENT INFORMATION CIRCULAR

Solicitation of Proxies

This management information circular is furnished in connection with the solicitation of proxies by the management of HudBay Minerals Inc. (the "Company") for use at the annual and special meeting of shareholders (the "Meeting") of the Company to be held at the time and place and for the purposes set forth in the accompanying Notice of Meeting. References in this management information circular to the Meeting include any adjournment or adjournments thereof. It is expected that the solicitation will be primarily by mail, however, proxies may also be solicited personally by regular employees of the Company and the Company may use the services of an outside proxy solicitation agency to solicit proxies. The cost of solicitation will be borne by the Company.

The board of directors of the Company (the "Board") has fixed the close of business on May 17, 2005 as the record date, being the date for the determination of the registered holders of securities entitled to receive notice of the Meeting. Duly completed and executed proxies must be received by the Company's transfer agent at the address indicated on the enclosed envelope no later than 10:30 a.m. (Toronto time) on June 21, 2005, or no later than 48 hours (excluding Saturdays and holidays) before the time of any adjourned Meeting.

Unless otherwise stated, the information contained in this management information circular is as of May 27, 2005. This management information circular contains references to United States dollars and Canadian dollars. All dollar amounts referenced, unless otherwise indicated, are expressed in Canadian dollars and United States dollars are referred to as "United States dollars" or "US$".

Appointment and Revocation of Proxies

The persons named in the enclosed form of proxy are officers and/or directors of the Company. A shareholder desiring to appoint some other person, who need not be a shareholder, to represent him at the Meeting, may do so by inserting such person's name in the blank space provided in the enclosed form of proxy or by completing another proper form of proxy and, in either case, depositing the completed and executed proxy at the office of the Company's transfer agent indicated on the enclosed envelope no later than 10:30 a.m. (Toronto time) on June 21, 2005, or no later than 48 hours (excluding Saturdays and holidays) before the time of any adjourned Meeting.

A shareholder forwarding the enclosed proxy may indicate the manner in which the appointee is to vote with respect to any specific item by checking the appropriate space. If the shareholder giving the proxy wishes to confer a discretionary authority with respect to any item of business, then the space opposite the item is to be left blank. The shares represented by the proxy submitted by a shareholder will be voted in accordance with the directions, if any, given in the proxy.

A proxy given pursuant to this solicitation may be revoked by an instrument in writing executed by a shareholder or by a shareholder's attorney authorized in writing (or, if the shareholder is a corporation, by a duly authorized officer or attorney) and deposited either at the registered office of the Company (6 Adelaide Street East, Suite 300, Toronto, Ontario M5C 1H6; Attention: Vice-President and General Counsel) at any time up to and including the last business day preceding the day of the Meeting or with the Chairman of the Meeting on the day of the Meeting or in any other manner permitted by law.

Exercise of Discretion by Proxies

The persons named in the enclosed form of proxy will vote the shares in respect of which they are appointed in accordance with the direction of the shareholders appointing them. In the absence of such direction, such shares will be voted in favour of the passing of all the resolutions described below. The enclosed form of proxy confers discretionary authority upon the persons named therein with respect to amendments or variations to matters identified in the Notice of Meeting and with respect to other matters which may properly come before the Meeting. At the time of printing of this management information circular, management knows of no such amendments, variations or other matters to come before the Meeting. However, if any other matters which are not now known to management should properly come before the Meeting, the proxy will be voted on such matters in accordance with the best judgment of the named proxies.

Voting by Non-Registered Shareholders

Only registered shareholders of the Company or the persons they appoint as their proxies are permitted to vote at the Meeting. Most shareholders of the Company are "non-registered" shareholders ("Non-Registered Shareholders") because the shares they own are not registered in their names but are instead registered in the name of the brokerage firm, bank or trust company through which they purchased the shares. Shares beneficially owned by a Non-Registered Shareholder are registered either: (i) in the name of an intermediary (an "Intermediary") that the Non-Registered Shareholder deals with in respect of the shares of the Company (Intermediaries include, among others, banks, trust companies, securities dealers or brokers and trustees or administrators of self-administered RRSPs, RRIFs, RESPs and similar plans); or (ii) in the name of a clearing agency (such as The Canadian Depository for Securities Limited) of which the Intermediary is a participant. In accordance with applicable securities law requirements, the Company will have distributed copies of the Notice of Meeting, this management information circular, the form of proxy, the supplemental mailing list return card and the 2004 annual report (collectively, the "Meeting Materials") to the clearing agencies and Intermediaries for distribution to Non-Registered Shareholders.

Intermediaries are required to forward the Meeting Materials to Non-Registered Shareholders unless a Non-Registered Shareholder has waived the right to receive them. Intermediaries often use service companies to forward the Meeting Materials to Non-Registered Shareholders. Generally, Non-Registered Shareholders who have not waived the right to receive Meeting Materials will either:

(i): be given a voting instruction form which is not signed by the Intermediary and which, when properly completed and signed by the Non-Registered Shareholder and returned to the Intermediary or its service company, will constitute voting instructions (often called a "voting instruction form") which the Intermediary must follow. Typically, the voting instruction form will consist of a one page pre-printed form. Sometimes, instead of the one page pre-printed form, the voting instruction form will consist of a regular printed proxy form accompanied by a page of instructions which contains a removable label with a bar-code and other information. In order for the form of proxy to validly constitute a voting instruction form, the Non-Registered Shareholder must remove the label from the instructions and affix it to the form of proxy, properly complete and sign the form of proxy and submit it to the Intermediary or its service company in accordance with the instructions of the Intermediary or its service company; or
(ii): be given a form of proxy which has already been signed by the Intermediary (typically by a facsimile, stamped signature), which is restricted as to the number of shares beneficially owned by the Non-Registered Shareholder but which is otherwise not completed by the Intermediary. Because the Intermediary has already signed the form of proxy, this form of proxy is not required to be signed by the Non-Registered Shareholder when submitting the proxy. In this case, the Non-Registered Shareholder who wishes to submit a proxy should properly complete the form of proxy and deposit it with the Company, c/o Equity Transfer Services Inc., Suite 420, 120 Adelaide Street West, Toronto, Ontario M5H 4C3.

In either case, the purpose of these procedures is to permit Non-Registered Shareholders to direct the voting of the shares of the Company they beneficially own. Should a Non-Registered Shareholder who receives one of the above forms wish to vote at the Meeting in person (or have another person attend and vote on behalf of the Non-Registered Shareholder), the Non-Registered Shareholder should strike out the persons named in the form of proxy and insert the Non-Registered Shareholder or such other person's name in the blank space provided. In either case, Non-Registered Shareholders should carefully follow the instructions of their Intermediary, including those regarding when and where the proxy or voting instruction form is to be delivered.

A Non-Registered Shareholder may revoke a voting instruction form or a waiver of the right to receive Meeting Materials and to vote which has been given to an Intermediary at any time by written notice to the Intermediary provided that an Intermediary is not required to act on a revocation of a voting instruction form or of a waiver of the right to receive Meeting Materials and to vote which is not received by the Intermediary at least seven (7) days prior to the Meeting.

Interest of Certain Persons in Matters to be Acted Upon

Directors and executive officers of the Company have an interest in the resolution concerning the establishment of the Company's share option plan (the "2005 SOP") in compliance with the rules of the Toronto Stock Exchange (the "TSX") as such persons are eligible to be granted options under the 2005 SOP.

Voting Securities and Principal Holders Thereof

As of May 27, 2005, 80,939,613 common shares (the "Common Shares") in the capital of the Company were issued and outstanding. Each Common Share entitles the holder thereof to one vote on all matters to be acted upon at the Meeting. The record date for the determination of shareholders entitled to receive notice of the Meeting has been fixed at May 17, 2005. In accordance with the provisions of the Business Corporations Act (Ontario) (the "OBCA"), the Company will prepare a list of holders of Common Shares as of such record date. Each holder of Common Shares named in the list will be entitled to vote the shares shown opposite his or her name on the list at the Meeting, except to the extent that (a) the shareholder has transferred any of his or her shares after the record date, and (b) the transferee of those shares produces properly endorsed share certificates or otherwise establishes that he or she owns such shares and demands not later than ten days prior to the Meeting that his or her name be included in the list before the Meeting, in which case the transferee is entitled to vote his or her shares at the Meeting. All such holders of record of Common Shares are entitled either to attend and vote thereat in person the Common Shares held by them or, provided a completed and executed proxy shall have been delivered to the Company's transfer agent within the time specified in the attached Notice of Meeting, to attend and vote thereat by proxy the Common Shares held by them.

To the knowledge of the directors and executive officers of the Company, as of the date hereof, the only person or company who beneficially owns, directly or indirectly, or exercises control or direction over, voting securities of the Company carrying more than 10% of the voting rights attached to any class of voting securities of the Company is as follows:

Name		Number of Common Shares		Percentage of Outstanding Common Shares
DKR Saturn Management L.P., in its capacity as investment manager for certain investment funds		8,549,332		10.56%

Defined Benefit or Actuarial Plan Disclosure

The following Named Executive Officers participate in the Company's defined benefit pension plan (the "Pension Plan"): Thomas A. Goodman, Brian D. Gordon, Alan Hair, Peter R. Jones, John L. Knowles and H. Russell Rood.

The Pension Plan is based on 2% of the average of the member's earnings during the 36 consecutive months of continuous service within the 10 year period immediately preceding the member's retirement, death or termination of continuous service, in which the highest average is attained, multiplied by the member's credited service.

The formula contains a partial offset for the Canada Pension Plan benefit. The pension is payable for life with a guarantee period of five years. In order to provide a survivor benefit of 60% of the basic pension, the amount shown on the table below would have to be reduced.

For purpose of the Pension Plan, earnings consist of an employee's basic compensation received in the plan year from the Company as reported for income tax purposes exclusive of: (i) payments of overtime, (ii) bonuses and director's fees, (iii) allowances and benefits which are taxable as set out in the Income Tax Act (Canada). All payments in excess of those amounts required under the provisions of the Canada Labour Code made as a consequence of termination of employment.

Pension Plan Table

The following table reflects the estimated annual pension benefit payable under the Pension Plan at age 62.

In addition, Mr. Jones shall be entitled to receive an annual cash bonus, with such bonus in 2005 to be a minimum of 50% and maximum of 100% of Mr. Jones' basic remuneration in such year. The annual cash bonus for 2006 and subsequent years shall be a minimum of 25% and a maximum of 100% of Mr. Jones' basic remuneration in the applicable year.

Pursuant to his agreement, Mr. Jones is provided with housing and car allowances. Mr. Jones is also entitled to participate in the Company's stock option program and the Pension Plan. His agreement provides that in the event that Mr. Jones' employment is terminated, other than for cause, he shall be entitled to three years of severance compensation. Each year of severance compensation shall be based on Mr. Jones' then base salary plus 25% of his maximum bonus entitlement, whichever is greater. Each year of severance compensation will then be increased by the value of the health care and pension payments that would been received by or made on behalf of or in respect of Mr. Jones for each such year. In the event that Mr. Jones' employment ceases in circumstances where he is entitled to severance compensation, or he otherwise retires from active employment, he shall continue to be entitled to exercise any stock options that have been granted.

The agreements with each of Mr. Knowles, Mr. Gordon and Mr. Rood, which are for initial three-year periods, stipulate, among other things, an initial base salary of $250,000 per annum, reviewable annually. In addition, each of Mr. Knowles and Mr. Gordon shall be entitled to receive an annual cash bonus, with such bonus in 2005 to be a minimum of 25% and maximum of 75% of their respective basic remuneration in such year. Their annual cash bonus for 2006 and subsequent years shall be a maximum of 75% of their respective basic remuneration in the applicable year, with no minimum entitlement. Mr. Rood shall be entitled to receive an annual cash bonus, with such bonus in 2005 to be a minimum of 25% and maximum of 100% of his basic remuneration in such year. The annual cash bonus for 2006 and subsequent years shall be a maximum of 100% of his basic remuneration in the applicable year, with no minimum entitlement. Each of the parties was also awarded a bonus of $100,000 in connection with the completion of the Acquisition, with one-third of such bonus paid during 2004, a further one-third to be paid on June 21, 2005 and the final one-third to be paid on December 21, 2005, provided however that any such payments shall not be made if the party resigns or is terminated for cause prior to such payment becoming due. (Mr. Knowles has announced his intention to resign his position as of June 30, 2005.) Mr. Rood is provided with housing and car allowances. Each party is also entitled to participate in the Company's stock option program and the Pension Plan. Each of their agreements provides that in the event that the party's employment is terminated, other than for cause, the party will be entitled to two years of severance compensation.

Norman Anderson and James W. Ashcroft. The Compensation Committee was appointed on February 2, 2005.

Report on Executive Compensation

Prior to the Acquisition, the Company primarily relied on a combination of cash and option compensation. The Board compensated its executive officers what it considered to be reasonable given the Company's then status as a junior resource company. Prior to the completion of the Acquisition, the Board agreed to certain compensation arrangements that would be implemented post-closing of the Acquisition. Following the Acquisition, the Company undertook a formal approach to executive compensation and in February 2005, established a compensation committee and adopted a Charter of the Compensation Committee of the Board. Prior to the appointment of the Compensation Committee and following the Acquisition, the Board was responsible for compensation paid to executive officers. During this period, the Board considered the objectives of: (i) recruiting and retaining the executives and senior management critical to the success of the Company and the enhancement of shareholder value; (ii) providing fair and competitive compensation; (iii) balancing the interests of management and shareholders of the Company; and (iv) rewarding performance, both on an individual basis and with respect to the business in general. In order to achieve these objectives, the compensation arrangements with the Company's executive officers contemplates the following components: (i) base salary; (ii) bonus; (iii) retention and (c) long-term incentive in the form of stock options.

Base Salary

The base salary of each particular executive officer was determined by an assessment by the Board and now by the Compensation Committee of such executive's experience and performance, a consideration of competitive compensation levels in companies similar to the Company and a review of the performance of the Company as a whole and the role such executive officer played in such corporate performance.

Bonus

Bonuses are performance based short-term financial incentives. Bonuses are based on certain indicators such as personal performance, team performance and/or corporate financial performance.

Long-Term Incentive

The Company provides a long-term incentive by granting options to executive officers. The options granted permit executives to acquire Common Shares at an exercise price equal to the closing price of the Common Shares under option on the trading day immediately preceding the date on which the option was granted. The objective of granting options is to encourage executives to acquire an ownership interest in the Company over a period of time, which acts as a financial incentive for such executive to consider the long-term interests of the Company and its shareholders.

Compensation of Chief Executive Officer

The Compensation Committee currently presents its recommendations to the Board with respect to the Chief Executive Officer's compensation. Prior to the appointment of the Compensation Committee, the Board was responsible for the Chief Executive Officer's compensation. The components of the Chief Executive Officer's compensation are the same as those which apply to the other senior executive officers of the Company, namely base salary, bonus, retention and long-term incentives in the form of stock options. In setting the current Chief Executive Officer's salary in 2004, the Board reviewed salaries paid to other senior officers in the Company, salaries paid to other chief executive officers in the mining industry and the incoming Chief Executive Officer's potential impact on the achievement of the Company's objectives.

TSXV SOP

This section provides brief summary disclosure of the TSXV SOP. Reference is made to the heading "Approval and Ratification of 2005 SOP", for full summary disclosure of the 2005 SOP, in accordance with the rules of the TSX. It is anticipated that the 2005 SOP will become the operative stock option plan of the Company, provided requisite shareholder approval is received, ratifying and approving its implementation. If shareholders approve the 2005 SOP, on a going forward basis, all future stock option grants by the Company will be made pursuant to the 2005 SOP. Notwithstanding the foregoing, any options previously granted under the TSXV SOP will continue to be governed by the terms and conditions of the TSXV SOP. There are currently 60,000 options that remain exercisable under the TSXV SOP. The TSXV SOP was established on July 9, 2002 and was last amended on July 5, 2004. The TSXV SOP was designed to encourage directors, senior officers, employees and consultants and other designated persons to own Common Shares. Options may be granted under the TSXV SOP only to directors, senior officers, employees, consultants and those of the Company's and other designated persons as designated from time to time by the Board. The number of Common Shares that may be reserved for issuance under the TSXV SOP is limited to 10% of the issued and outstanding Common Shares as at the date of the grant of options. The maximum number of Common Shares that may be reserved for issuance to any one person under the TSVX SOP is 5% of the Common Shares outstanding at the date of the grant (calculated on a non-diluted basis). Any shares subject to an option that for any reason is cancelled or terminated prior to exercise will be available for a subsequent grant under the TSXV SOP. The option price of any Common Shares cannot be less than the closing price of the Common Shares on the day immediately preceding the day upon which the option is granted, less any discount permitted by the policies of the TSXV. Options granted under the TSXV SOP may be exercised during a period not exceeding ten years, subject to earlier termination upon the termination of the optionee's employment, upon the optionee ceasing to be an employee, senior officer, director or consultant or ceasing to have a designated relationship with the Company or upon the optionee retiring, becoming permanently disabled or dying. The options are non-transferable. The TSXV SOP contains provisions for adjustment in the number of Common Shares issuable thereunder in the event of a subdivision, consolidation, reclassification or change of the Common Shares, a merger or other relevant change in our capitalization.

Indebtedness of Directors and Executive Officers

None of the directors, executive officers and employees of the Company or any of its subsidiaries and former directors, executive officers and employees of the Company or any of its subsidiaries had any indebtedness outstanding to the Company or any of its subsidiaries during the financial year ended December 31, 2004 and as at the date hereof.

Interest of Informed Persons in Material Transactions

Other than as described in this management information circular, since the commencement of the Company's last completed financial year, no informed person of the Company, nominee for election as a director of the Company, or any associate or affiliate of an informed person or nominee, has or had any material interest, direct or indirect, in any transaction or any proposed transaction which has materially affected or will materially affect the Company or any of its subsidiaries.

Statement of Corporate Governance Practices

The Company and the Board recognize the importance of corporate governance to the effective management of the Company and to the protection of its employees and shareholders and have been enhancing the Company's corporate governance practices. The Company's approach to significant issues of corporate governance is designed with a view to ensuring that the business and affairs of the Company are effectively managed so as to enhance shareholder value.

Canadian securities regulators are currently engaged in a review of the corporate governance standards applicable to Canadian public companies. In 2004, a number of proposed Multilateral Instruments and National Instruments and Policies were published for comment. In October 2004, the Canadian Securities Administrators published National Instrument 58-101 Disclosure of Corporate Governance (the "Instrument") and National Policy 58-102 Corporate Governance Guidelines (the "Policy"). The Instrument and the Policy are expected to be effective and apply to disclosure in circulars which are filed following financial years ending on or after June 30, 2005. Once effective, the Instrument and the Policy will replace the Corporate Governance Policy of the TSX. During the transition period, the Company is disclosing its corporate governance practices as compared to the current TSX guidelines contained in Part IV, Sections 472-475 of the TSX Company Manual (the "Manual"). The Company is currently reviewing the Instrument and the Policy and is reviewing its corporate governance practices with a view to implementing any applicable changes where appropriate.

The Company's disclosure addressing each of the TSX's current corporate governance guidelines is attached as Schedule "A" to this management information circular. Supplementary disclosure regarding the Company's adoption or planned adoption of practices set out in the Instrument have been added to the disclosure in Schedule "A". This disclosure statement, including Schedule "A", has been approved by the Board.

Audit Committee

Information regarding the Company's Audit Committee is contained in the Company's renewal annual information form dated March 29, 2005 under the heading "Audit Committee Disclosure" and a copy of the Audit Committee Charter is attached to the renewal annual information form as Schedule "B".

The major features of the 2005 SOP can be summarized as follows.

The Board, the Compensation Committee or another committee appointed for such purposes by the Board may from time to time grant to directors, officers or employees of the Company (collectively, the "Eligible Persons") 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 Executive Committee or committee. The purpose of the 2005 SOP is to attract, retain and motivate persons as directors, officers and key employees of the Company and its subsidiaries and to advance the interests of the Company by providing such persons with the opportunity, through share options, to acquire an increased proprietary interest in the Company.

The maximum number of Common Shares that may be reserved for issuance for all purposes under the 2005 SOP is 10% of the issued and outstanding shares as at the date of the grant. Shares in respect of which options are not exercised as well as shares in respect of which options are exercised, shall become available for the grant of subsequent options under the 2005 SOP. No fractional Common Shares may be purchased or issued under the 2005 SOP. The rules of the TSX provide that every three years after institution, all unallocated options under a security based compensation arrangement which does not have a fixed maximum number of securities issuable must be approved by a majority of the issuer's directors, a majority of the issuer's unrelated directors and the security holders.

This maximum number of options that may be granted under the 2005 SOP includes Common Shares previously issued under the TSXV SOP. Notwithstanding the foregoing, no more than 5% of the issued and outstanding Common Shares shall be available for issuance pursuant to Incentive Stock Options (defined as an option to purchase Common Shares granted under the 2005 SOP with the intention that it qualify as an "incentive stock option" as that term is defined in Section 422 of the U.S. Internal Revenue Code of 1986, as amended (the "Code")). All references in the 2005 SOP to the Common Shares outstanding at the date of issuance shall mean that number of Common Shares determined on the basis of the number of Common Shares that are outstanding immediately prior to the share issuance in question.

The Board has the authority under the 2005 SOP to establish the option price at the time each share option is granted. The option price may not be lower than the market price (the "Market Price"), i.e. the closing price, of the Common Shares as traded on the TSX on the last trading day preceding the date on which the option is approved by the Board. In addition, the option price of Common Shares which are the subject of any Incentive Stock Option granted to an employee who, at the time the option is granted, owns stock possessing at least ten percent of the total combined voting power of all classes of shares of the Company or of its subsidiary corporations (as subsidiary is defined in Section 424 of the Code) (a "10% Shareholder") shall in no circumstances be lower than 110% of the Market Price of the Common Shares at the date of the grant of the option.

Options granted under the 2005 SOP must be exercised no later than 10 years after the date of grant. Options are not transferable other than by will or the laws of dissent and distribution and may be exercised during the lifetime of the optionee only by the optionee. At no time shall the period during which an Incentive Stock Option granted to a 10% Shareholder shall be exercisable exceed five years.

During each 12 month period from the date of the grant of the option, within the first three years of the grant, the optionee may take up not more than 33¹/3%, 33¹/3% and 33¹/3%, respectively, of the Common Shares covered by the option, with the first 33¹/3% of the Common Shares covered by the option being exercisable immediately during the first 12 month period following the grant thereof; provided, however, that if the number of Common Shares taken up under the option during any such 12 month period is less than the amount of the Common Shares that are subject to the options which have then vested, the optionee shall have the right, at any time or from time to time during the remainder of the term of the option, to purchase such number of Common Shares subject to the option which were purchasable, but not purchased by him or her during such 12 month period. To the extent that the option price of Common Shares (determined on the date of grant) with respect to which Incentive Stock Options are exercisable for the first time during any calendar year (under the 2005 SOP and all other stock option plans of the Company) exceeds US$100,000, such portion in excess of US$100,000 shall be treated as a Nonqualified Stock Option (defined as an option to purchase Common Shares granted under the 2005 SOP (for United States purposes) that is other than an Incentive Stock Option).

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, 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. Notwithstanding the foregoing, in the event the optionee ceases to be an Eligible Person by reason of his or her retirement, then, such optionee shall have the right, at any time or from time to time during the remainder of the term of the option, to purchase such number of Common Shares that remain subject to the option, provided that any options held by an optionee at the time of his or her retirement, shall remain subject to the 2005 SOP's vesting provisions. For the purposes of this section, the term "retirement" mean the normal retirement date for the Eligible Person or such other adjusted date as may be agreed upon by the Eligible Person and the Company.

The Company provides no financial assistance to facilitate the purchase of Common Shares to directors, officers or employees who hold options granted under the 2005 SOP. Subject to corporate and other applicable laws, the Company may permit an optionee to elect to pay the option Price by authorizing a third party to sell Common Shares (or a sufficient portion of such Common Shares) acquired upon exercise of the option and remit to the Company a sufficient portion of the sale proceeds to pay the entire option price and any tax withholding resulting from such exercise. In addition, the option price for Common Shares purchased under an option may be paid, either singly or in combination with one or more of the alternative forms of payment or such other consideration as the Board may permit.

The 2005 SOP provides that in the event of a Change of Control, all options outstanding shall be immediately exercisable at the discretion of the Board. A "Change of Control" means the occurrence of any one or more of the following events:

(i): the sale, lease, exchange or other disposition, in a single transaction or a series of related transactions, of all or substantially all of the assets, rights or properties of the Company;
(ii): any person, entity or group of persons or entities acting jointly or in concert (an "Acquiror") acquires or acquires control (including without limitation, the right to vote or direct the voting) of Common Shares, which, when added to the Common Shares owned of record or beneficially by the Acquiror to which the Acquiror has the right to direct the voting, would entitle the Acquiror and/or associates and/or affiliates of the Acquiror to cast or direct the casting of 30% or more of the votes attached to all of the Company's outstanding voting shares which may be cast to elect directors of the Company or the successor Company (regardless of whether a meeting has been called to elect directors); or
(iii): the Board adopts a resolution to the effect that a Change of Control as defined herein has occurred or is imminent.

Board and requisite shareholder and regulatory approval shall be required for any of the following amendments to be made to the 2005 SOP:

(i): any amendment to the number of securities issuable under the 2005 SOP, including an increase to a fixed maximum number of securities or a change from a fixed maximum number of securities to a fixed maximum percentage. A change to a fixed maximum percentage which was previously approved by shareholders will not require additional shareholder approval;
(ii): any change to the definition of "Eligible Person" which would have the potential of broadening or increasing insider participation;
(iii): the addition of any form of financial assistance;
(iv): any amendment to a financial assistance provision which is more favourable to participants;
(v): the addition of a cashless exercise feature, payable in cash or securities which does not provide for a full deduction of the number of underlying securities from the 2005 SOP reserve;
(vi): the addition of a deferred or restricted share unit or any other provision which results in Eligible Persons receiving securities while no cash consideration is received by the Company;
(vii): discontinuance of the 2005 SOP; and
(viii): and any other amendments that may lead to significant or unreasonable dilution in the Company's outstanding securities or may provide, additional benefits to Eligible Persons, especially insiders of the Company, at the expense of the Company and its existing shareholders.

The Board may, subject to receipt of requisite regulatory approval, where required, in its sole discretion make all other amendments to the 2005 SOP that are not of the type contemplated above including, without limitation:

(i): amendments of a "housekeeping" nature;
(ii): a change to the vesting provisions of a security or the 2005 SOP;
(iii): a change to the termination provisions of a security or the 2005 SOP which does not entail an extension beyond the original expiry date; and
(iv): the addition of a cashless exercise feature, payable in cash or securities, which provides for a full deduction of the number of underlying securities from the 2005 SOP reserve.

Notwithstanding the provisions above with respect to Board approval only, the Company shall additionally obtain requisite shareholder approval in respect of amendments to the 2005 SOP that are contemplated above, to the extent such approval is required by any applicable laws or regulations (including without limitation, Section 422 of the Code). No amendment to the 2005 SOP may alter or impair any of the terms of any option previously granted to an optionee under the 2005 SOP without the written consent of the optionee.

Additionally, any change or adjustment to an outstanding Incentive Stock Option shall not, without the written consent of the optionee, be made in a manner so as to constitute a "modification" that would cause such Incentive Stock Option to fail to continue to qualify as an Incentive Stock Option.

As at May 17, 2005 options to acquire 3,660,000 Common Shares, representing approximately 4.52% of the issued and outstanding Common Shares had been conditionally granted pursuant to the 2005 SOP, subject to TSX and shareholder approval. Accordingly, as at May 27, 2005, being the date of this management information circular, an additional 4,756,961 options are available for grant under the 2005 SOP, subject to TSX and shareholder approval of the 2005 SOP, after taking into account the remaining 60,000 options exercisable under the TSXV SOP.

The rules of the TSX provide that it is appropriate to limit insider participation in a vote to approve a 2005 SOP if, over a defined period of time, the securities issued and issuable to insiders of the Company could exceed 10% of an issuer's issued and outstanding securities. This would include securities currently under grant (including outstanding options) and securities available to be granted to insiders under all arrangements.

To avoid the exclusion of eligible insider votes, issuers would have to provide that: (i) the number of securities issuable to insiders, at any time, under all security based compensation arrangements, cannot exceed 10% of the issued and outstanding securities; and (ii) the number of securities issued to insiders, within any one year period, under all security based compensation arrangements, cannot exceed 10% of the issued and outstanding securities. As the 2005 SOP does not contain the foregoing provisions, insiders of the Company that are entitled to receive a benefit under the 2005 SOP are not eligible to vote their securities in respect of the security approvals required (the "Excluded Insiders"). Therefore, to the knowledge of management of the Company, a total of 11,833 Common Shares held by the directors and officers of the Company and its subsidiaries cannot be voted on the resolution approving and ratifying the 2005 SOP (the "2005 SOP Resolution"). The following individuals are prohibited from voting on the 2005 SOP Resolution: M. Norman Anderson, James W. Ashcroft, Richard W. Brissenden, Ian L.T. Conn, Ronald P. Gagel, Thomas A. Goodman, Brian D. Gordon, Peter R. Jones, Alan Hair, Richard Knight, John L. Knowles, Mick Lawler, Allen J. Palmiere and H. Russell Rood.

In order to be effective, the 2005 SOP Resolution must be passed by a simple majority of the votes cast by the shareholders of the Company who vote in respect of such resolution, exclusive of the Excluded Insiders.

The Board recommends that shareholders vote for the adoption of the 2005 SOP Resolution. In the absence of instructions to the contrary, the accompanying form of proxy will be voted for the 2005 SOP Resolution.

The text of the 2005 SOP Resolution to be submitted to shareholders (exclusive of the Excluded Insiders) at the Meeting is set forth below, subject to such amendments, variations or additions as may be approved at the Meeting:

"NOW THEREFORE BE IT RESOLVED THAT:

1.: The Company's stock option plan approved by the directors of the Company on May 6, 2004, as set forth in the Company's management information circular dated May 27, 2005 be and the same is hereby approved and ratified.
2.: Any director or officer of the Company is hereby authorized and directed, on behalf of the Company, to execute or cause to be executed, under the seal of the Company or otherwise, and to deliver or cause to be delivered, all such other documents, instruments and assurances, and to do or cause to be done all acts and things, as in the opinion of such director or officer of the Company may be necessary or desirable to carry out the intent of the foregoing resolution."

Continuance under the Canada Business Corporations Act

The Company is a corporation incorporated under the OBCA. Management wishes to effect the continuance (the "Continuance") of the Company from the Province of Ontario to Canada. As a result of the Continuance, the corporate legislation that governs the Company will cease to be the OBCA, and the Company will be governed by the Canada Business Corporations Act (the "CBCA"). In connection with the Continuance, the Company proposes to change the province in which its registered office is located from the Province of Ontario to the Province of Manitoba. Management wishes to relocate the registered office of the Company to the Province of Manitoba in order to bring the Company closer to its wholly-owned subsidiary HBMS's centre of operations at Flin Flon, Manitoba. If the special resolution approving the Continuance is passed at the Meeting, it is proposed that the application for approval to continue the Company under the CBCA will be made as soon as practicable following the Meeting.

If the Continuance is approved, the articles of continuance will be adopted to replace the existing articles of the Company (the equivalent of a Certificate of Incorporation) and will constitute the governing instrument of the continued corporation under the CBCA. The existing articles of the Company will be adopted and continued federally, except to the extent that they may conflict with the CBCA. A copy of the Articles of Continuance is attached hereto as Schedule "E".

The CBCA provides shareholders with substantially the same rights (including rights of dissent and appraisal and rights to bring derivative actions and oppression actions) as are available to shareholders under the OBCA. However, there are certain differences between the two statutes and the regulations thereunder. The following is a summary of certain material differences between the CBCA and the OBCA. This summary is not an exhaustive review of the two statutes. Reference should be made to the full text of both statutes and the regulations thereunder for particulars of any differences between them, and shareholders are urged to consult their legal or other professional advisors with regard to the implications of the Continuance that may be of importance to them.

Director Residency Requirements. Under the OBCA, a majority of a company's directors must be resident Canadians. Under the CBCA, subject to certain exceptions, at least 25% of a company's directors must be resident Canadians.

Place of Shareholders' Meetings. Under the OBCA, a shareholders' meeting may be held at such place in or outside Ontario (including outside Canada) as the directors may determine. Under the CBCA, a shareholders' meeting may be held at any place in Canada, or at a place outside Canada if such place is specified in the articles of the company or if all the shareholders entitled to vote at the meeting agree that the meeting is to be held at that place.

Solicitation of Proxies. Under the OBCA, a person who solicits proxies, other than by or on behalf of management of the company, must send a dissident's proxy circular in prescribed form to each shareholder whose proxy is solicited and to certain other recipients.

Under the CBCA, proxies may be solicited other than by or on behalf of management of the company without the sending of a dissident's proxy circular if:

•: proxies are solicited from 15 or fewer shareholders; or
•: the solicitation is conveyed by public broadcast, speech or publication containing certain of the information that would be required to be included in a dissident's proxy circular.

Furthermore, under the CBCA, the definition of "solicit" and "solicitation" specifically excludes:

•: certain public announcements by a shareholder of how he or she intends to vote and the reasons for that decision;
•: communications for the purpose of obtaining the number of shares required for a shareholder proposal; and
•: certain other communications made other than by or on behalf of management of the company, including communications by one or more shareholders concerning the business and affairs of the company or the organization of a dissident's proxy solicitation where no form of proxy is sent by or on behalf of such shareholders, by financial and other advisors in the ordinary course of business to shareholders who are their clients, or by any person who does not seek directly or indirectly the power to act as proxy for a shareholder.

Voting at Shareholders' Meetings. Under the OBCA, where a company fixes a record date for the determination of shareholders entitled to vote at a shareholders' meeting and a shareholder transfers shares after the record date, the transferee of such shares is entitled to vote such shares at the meeting if the transferee establishes that he or she owns the shares and demands, not later than 10 days before the date of the meeting, that his or her name be included in the list of shareholders entitled to vote at the meeting. If no record date is fixed and a list of shareholders entitled to vote at the meeting is prepared as of the date (the "deemed record date") preceding the date on which notice of the meeting is given, a transferee of shares after the deemed record date is entitled to vote such shares under similar circumstances. Under the CBCA, shareholders are entitled to vote only those shares held by them on the record date for voting or the deemed record date for voting, as the case may be. Transferees of shares after the record date or the deemed record date, as the case may be, are not entitled to vote the transferred shares at the meeting.

Notice of Shareholders' Meetings. Under the OBCA, a public company must give notice of a meeting of shareholders not less than 21 days and not more than 50 days before the meeting. Under the CBCA, notice of a meeting of shareholders must be provided not less than 21 days and not more than 60 days before the meeting. However, public companies incorporated under either statute are currently subject to the requirements of National Instrument 54-101 which provides for minimum notice periods greater than the minimum 21 day period in either statute.

Telephonic or Electronic Meetings. Under the OBCA, a meeting of shareholders may be held by telephonic or electronic means (and shareholders may participate in and vote at the meeting by such means) only if permitted by the articles or by-laws of the company. Under the CBCA, unless a company's by-laws provide otherwise, if a company provides shareholders with a telephonic, electronic or other communication facility that permits all participants to communicate adequately with each other during the meeting, then any person entitled to attend the meeting may participate by such means.

Shareholder Proposals. Under the OBCA, only registered shareholders may submit shareholder proposals relating to matters which the shareholder wishes to raise at a shareholders' meeting.

Under the CBCA, shareholder proposals may be submitted by both registered and beneficial shareholders, provided that:

•: the shareholder owned, of record or beneficially, for at least six months prior to the submission of the proposal, voting shares at least equal to 1% of the total number of outstanding voting shares of the company or whose fair market value is at least $2,000, whichever is less; or
•: the proposal must have the support of persons who in the aggregate have owned, of record or beneficially, such number of voting shares for such period.

Registered Office. Under the OBCA, a company's registered office must be located in Ontario. Under the CBCA, a company's registered office may be located at any place in Canada.

Financial Assistance. Under the OBCA, a corporation may provide financial assistance by way of a loan, guarantee or otherwise to any person, provided that certain disclosure obligations are met in respect of loans to directors, officers and shareholders. There are no financial assistance provisions in the CBCA.

The directors of the Company may, notwithstanding requisite shareholder approval, abandon the application for the Continuance without further approval of the shareholders, all as provided under the OBCA. In making such determination, the directors in their discretion, will determine whether it is in the best interests of the Company to proceed with the Continuance, after considering all relevant factors at the particular time, whether or not foreseen at this date.

At the Meeting, shareholders will be asked to consider and, if deemed appropriate, to pass, with or without variation, a special resolution, in the form set out below (the "Continuance Resolution"), subject to such amendments, variations or additions as may be approved at the Meeting, approving the Continuance.

The Board recommends that shareholders vote for the adoption of the Continuance Resolution. In order to be effective, the Continuance Resolution must be approved by not less than two-thirds of the votes cast by the shareholders of the Company who vote in respect of the Continuance Resolution. In the absence of instructions to the contrary, the accompanying form of proxy will be voted for the Continuance Resolution.

The text of the Continuance Resolution to be submitted to shareholders at the Meeting is set forth below, subject to such amendments, variations or additions as may be approved at the Meeting:

"NOW THEREFORE BE IT RESOLVED AS A SPECIAL RESOLUTION THAT:

1.: the Company submit an Application for Authorization to Continue in Another Jurisdiction to the Ontario Ministry of Consumer and Business Services together with the consents of the Corporations Tax Branch of the Ontario Ministry of Finance and the Ontario Securities Commission and file Articles of Continuance with Corporations Canada continuing the Corporation as if it had been incorporated under the laws of Canada, such Articles of Continuance to be substantially in the form attached to the management information circular of the Company dated May 27, 2005 as Schedule "E", subject to such additions, deletions or other changes thereto, if any, as any one director or officer of the Company may consider necessary or desirable and shall approve;
2.: subject to such continuance without affecting the validity and existence of the Corporation by or under its Articles and of any act done thereunder, its Articles are hereby amended to make all changes necessary to conform to the Canada Business Corporations Act (the "CBCA") and by substituting for the provisions of its Articles the provisions set out in the Articles of Continuance, substantially in the form attached to the management information circular of the Company dated May 27, 2005 as Schedule "E", subject to such additions, deletions or other changes thereto, if any, as any one director or officer of the Company may consider necessary or desirable and shall approve;
3.: the Company is hereby authorized to make application to the Director (Ontario) to permit such continuance in accordance with section 181 of the Business Corporations Act (Ontario);
4.: the Company is hereby authorized to make application to the Director appointed under the CBCA, for the Company to be continued under the CBCA;
5.: following the continuance of the Company under the CBCA, the Company shall establish its registered office in such place in Manitoba as determined by the board of directors of the Company;
6.: the directors of the Company are hereby authorized to abandon the application for continuance of the Company at any time without further approval of the shareholders of the Company; and
7.: any director or officer of the Company is hereby authorized and directed, acting for, in the name of and on behalf of the Company, to execute or cause to be executed, under the seal of the Company or otherwise, and to deliver or cause to be delivered, such other documents and instruments, and to do or cause to be done all such other acts and things, as may in the opinion of such director or officer of the Company be necessary or desirable to carry out the intent of the foregoing resolutions."

Pursuant to the OBCA, a registered shareholder is entitled to dissent to the Continuance and be paid fair value for his, her or its Common Shares if such shareholder objects to the Continuance Resolution. A management summary of the registered shareholders' dissent rights is set forth below under the heading "Dissent Rights".

Dissent Rights

Section 185 of the OBCA provides registered holders of Common Shares, in connection with the vote on the Continuance, with the right to dissent and, if the Continuance is effected, to be paid by the Company the "fair value" of their shares, determined as of the close of business on the last business day before the Continuance Resolution is adopted. A summary of Section 185 of the OBCA providing for these rights is set out below. The summary is qualified in its entirety by reference to Section 185, the complete text of which is annexed hereto as Schedule "C" and forms a part of this management information circular.

Failure to strictly comply with the requirements of Section 185 of the OBCA may result in the loss of any right of dissent. The right of dissent provided for under Section 185 of the OBCA applies only to registered shareholders of the Company, and accordingly, only registered shareholders may exercise a right of dissent. Persons who are beneficial owners of Common Shares registered in the name of a broker, custodian, nominee or other intermediary who wish to exercise a right of dissent must make arrangements for the Common Shares beneficially owned by them to be registered in their name prior to the time the written objection is required to be received by the Company or, alternatively, make arrangements for the registered holder of their Common Shares to dissent on their behalf.

To comply with Section 185, a dissenting shareholder must send to the Company a written objection to the Continuance: (a) at or before the Meeting; or (b) if the Company did not send notice to the shareholder of the purpose of the Meeting or of their right to dissent, within a reasonable time after such shareholder learns that the Continuance Resolution was adopted and of such shareholder's right to dissent. An application may be made to the court by originating notice after the adoption of the Continuance Resolution by the Company or by a shareholder if such shareholder has sent an objection to the Company as set forth above, to fix the fair value of his, her or its Common Shares. If such a court application is made, the Company shall, unless the court otherwise orders, send to each dissenting shareholder a written offer to pay such shareholder an amount considered by the directors to be the fair value of the shares: (a) at least ten days before the date on which the application is returnable, if the Company is the applicant, or (b) within ten days after the Company is served with a copy of the originating notice, if a shareholder is the applicant.

On this court application, the court shall make an order: (a) fixing the fair value of the Common Shares of all dissenting shareholders who are parties to the application; (b) giving judgment in that amount against the Company and in favour of each of those dissenting shareholders; and (c) fixing the time within which the Company must pay that amount to a shareholder. On the first to occur of: (a) the Continuance being effected; (b) the making of an agreement between the dissenting shareholder and the Company as to the payment to be made by the Company for the dissenting shareholder's Common Shares; or (c) the pronouncement of the court order referred to above; the shareholder ceases to have any rights as a shareholder other than the right to be paid the fair value of his, her or its Common Shares in the amount agreed to or in the amount of the judgment, as the case may be. Until one of the events described above occurs, the shareholder may withdraw its dissent or the Company may rescind the Continuance Resolution, and in either event proceedings under Section 185 shall be discontinued.

The Company is prohibited from making a payment to a dissenting shareholder under Section 185 of the OBCA if there are reasonable grounds for believing that: (a) the Company is or would after the payment be unable to pay its liabilities as they become due; or (b) the realizable value of the Company's assets would thereby be less than the aggregate of its liabilities. In such event, and notwithstanding that a judgment has been given in favour of a dissenting shareholder as referred to above, the dissenting shareholder, by written notice delivered to the Company within 30 days after receiving a notice from the Company that it is unable lawfully to pay dissenting shareholders for their shares, may withdraw its notice of objection, in which case the Company is deemed to consent to the withdrawal and the shareholder is reinstated to its full rights as a shareholder. If the dissenting shareholder fails to deliver such notice, it retains a status as a claimant against the Company, to be paid as soon as the Company is lawfully able to do so or, in a liquidation, to be ranked subordinate to the rights of creditors of the Company but in priority to its shareholders.

The procedures required in connection with the exercise of rights under Section 185 of the OBCA are very technical, complex and in most cases, time-consuming and expensive. The sending of a notice of dissent does not deprive a shareholder of its right to vote against the Continuance Resolution; however, a vote against the Continuance Resolution does not constitute a notice of dissent.

Confirmation of By-Law Number 1

If the Continuance is approved and effected, By-Law Number 1 under the CBCA which has been conditionally approved by the Board, will be implemented as the Company's general by-law. Shareholders are being asked to confirm By-Law Number 1.

By-Law Number 1 is standard in its form and governs all aspects of the business and affairs of the Company, such as the establishment of a quorum for meetings of directors and shareholders, the conduct of such meetings, signing authorities, the appointment of officers, the description of the officers' duties, the establishment of committees of the Board, the authority of persons to contract on behalf of the Company and similar matters. The complete text of By-Law Number 1 is attached as Schedule "D" to this management information circular.

At the Meeting, shareholders will be asked to consider and, if deemed appropriate, to pass, with or without variation, a resolution, in the form set out below (the "By-Law Resolution"), subject to such amendments, variations or additions as may be approved at the Meeting, confirming By-Law Number 1.

The Board recommends that shareholders vote for the adoption of the By-Law Resolution. In order to be effective, the By-Law Resolution must be approved by not less than a majority of the votes cast by the shareholders of the Company who vote in respect of the By-Law Resolution. In the absence of instructions to the contrary, the accompanying form of proxy will be voted for the By-Law Resolution.

The text of the By-Law Resolution to be submitted to shareholders at the Meeting is set forth below, subject to such amendments, variations or additions as may be approved at the Meeting:

"NOW THEREFORE BE IT RESOLVED THAT:

1.: The general by-law, substantially in the form attached to the management information circular of the Company dated May 27, 2005 as Schedule "D" be, and it hereby is, confirmed as the new general by-law for the Company, subject to such additions, deletions or other changes thereto, if any, as any one director or officer of the Company may consider necessary or desirable and shall approve, to be effective upon the continuance of the Company pursuant to the federal laws of Canada; and
2.: any director or officer of the Company is hereby authorized and directed, acting for, in the name of and on behalf of the Company, to execute or cause to be executed, under the seal of the Company or otherwise, and to deliver or cause to be delivered, such other documents and instruments, and to do or cause to be done all such other acts and things, as may in the opinion of such director or officer of the Company be necessary or desirable to carry out the intent of the foregoing resolution."

HUDBAY MINERALS INC.
ALIGNMENT WITH TSX CORPORATE GOVERNANCE GUIDELINES

The following table indicates how the corporate governance practices of the Company align with the TSX Corporate Governance Guidelines (the "Guidelines"):

TSX Corporate Governance Guidelines		Corporate Governance Practices of the Company
1.	Board should explicitly assume responsibility for stewardship of the corporation, and specifically for:	The Board is responsible for the stewardship of the business and affairs of the Company and it reviews, discusses and approves various matters related to the Company's operations, corporate governance, strategic direction and organizational structure to ensure that the best interests of the Company and its shareholders are being served.

	a) Adoption of a strategic planning process	The responsibilities of the Board include the adoption of a strategic planning process and the approval, at least annually of a strategic plan that takes into account business opportunities and business risks identified by the Board and by the Audit Committee and monitoring the Company's performance against such plans.
		The Board monitors management on a regular basis. Management of the Company is aware of the need to obtain Board approval for major capital expenditures or significant corporate or business transactions outside of the normal course of business. Less significant activities which can be addressed by management are often reported to the Board, with whom management has a good working relationship.
	b) Identification of principal risks, and implementing risk management systems	The Board and its Audit Committee identify the principal risks of the Company's business and ensure the implementation of appropriate systems to manage such risks.
	c) Succession planning and monitoring senior management	The Board is responsible for succession planning including the selection, appointment and replacement of senior management and monitoring their performance.
	d) Communications policy	The Timely Disclosure, Confidentiality and Insider Trading Policy of the Company is reviewed by the Board periodically and provides that communications with all constituents will be made in a timely, accurate and effective manner.
		The Company communicates regularly with shareholders through press releases, as well as annual and quarterly reports. Investor and shareholder concerns are addressed on an on-going basis by the Chief Executive Officer of the Company.

TSX Corporate Governance Guidelines		Corporate Governance Practices of the Company
		The Company is dedicated to the maintenance of good shareholder relations and attempts to deal with any expressed concerns of shareholders in an effective and timely manner. The Company has few concerns or complaints expressed to it by shareholders, but attempts to deal with any concerns or complaints that it does receive effectively, in an informal manner.
	e) Integrity of internal control and management information systems	The Board and its Audit Committee are responsible to satisfy themselves that adequate procedures are in place to ensure the integrity of the Company's internal controls and management information systems.
2.	a) Majority of directors should be unrelated	Under the Charter of the Board, a director is considered to be independent if he or she has no direct or indirect material relationship which could, in the view of the Board, reasonably interfere with the exercise of a director's independent judgment. A related director is a director who is not an unrelated director.
		The Board is currently comprised of seven (7) members, six (6) of whom are considered to be unrelated directors under the Guidelines at the present time.
	b) If the corporation has a significant shareholder, the board should include directors who do not have interests in or relationships with the corporation or such significant shareholder	This guideline does not apply to the Company since it does not have a significant shareholder.
3.	Disclose, for each director, whether he is related, and how that conclusion was reached	Peter R. Jones is considered to be a related director because he is employed by the Company and is a member of management.
		Each of M. Norman Anderson, James W. Aschroft, Ian L.T. Conn, Ronald P. Gagel and Allen J. Palmiere is an unrelated director as none of these individuals has any business, employment or other relationships with the Company.
		The shareholdings of each current director is disclosed in the management information circular under the heading "Election of Directors".
4.	Appoint a committee of directors, composed exclusively of outside (non-management) directors, a majority of whom are unrelated, responsible for proposing to the full board new nominees to the board and for assessing directors on an ongoing basis	The Corporate Governance and Nominating Committee is responsible for recruiting new directors, proposing new director nominees to the Board and reviewing the performance and qualifications of existing directors. Each of the members of the Corporate Governance and Nominating Committee (M. Norman Anderson, James W. Ashcroft, Ian L.T. Conn and Allen J. Palmiere) is an outside (non-management) director and are each unrelated directors under the Guidelines.

TSX Corporate Governance Guidelines		Corporate Governance Practices of the Company
5.	Implement a process for assessing the effectiveness of the board, its committees and individual directors	The Corporate Governance Committee is responsible for reviewing, on a periodic basis, the size and composition of the Board and assessing the effectiveness of the Board as a whole, the committees of the Board and the contributions of individual directors.
6.	Provide an orientation and education program for new directors	The Corporate Governance Committee is responsible for providing an orientation and education program for new members of the Board. The preparation of a comprehensive orientation and continuing education program for directors is under review.
7.	Implement a process to examine the size of board, with a view to improving effectiveness	The Board is of the view that both its current size (seven (7) directors) and the proposed size of the Board (six (6) directors) is conducive to effective decision-making.
8.	The board should review compensation of directors in light of risks and responsibilities	The Compensation Committee reviews the adequacy and form of, and recommends to the Board, compensation including salary, bonus and other direct and indirect benefits received by directors to ensure that the compensation received by the directors accurately reflects the responsibilities involved in being an effective director, potential contribution to the Company's success and compensation paid to others in similar positions in the Company's industry.
9.	Committees of the board should generally be composed of outside (non-management) directors, a majority of whom are unrelated directors	There are four committees of the Board: the Audit Committee, the Compensation Committee, the Corporate Governance and Nominating Committee and the Environmental, Health and Safety Committee.
		The Audit Committee meets at least four times annually and reviews the annual and interim financial statements and other financial information of the Company. Through meetings with external auditors and senior management, the Audit Committee discusses, among other things, the effectiveness of the internal control procedures established for the Company. The members of the Audit Committee are Ronald P. Gagel (Chairman), Richard W. Brissenden and Allen J. Palmiere, all of whom are unrelated directors under the Guidelines.
		The Compensation Committee meets at least once each year or more frequently, as required, to review compensation for senior management. The members of the Compensation Committee are Allen J. Palmiere (Chairman), M. Norman Anderson, and James W. Ashcroft, all of whom are unrelated directors under the Guidelines.

TSX Corporate Governance Guidelines		Corporate Governance Practices of the Company
		The Corporate Governance Committee meets at least once each year or more frequently as circumstances require. The Corporate Governance Committee may ask members of management or others to attend meetings or to provide information as necessary. In addition, the Corporate Governance Committee or, at a minimum, the Chairman of such committee, may meet with the Company's in-house or external corporate counsel to discuss the Company's corporate governance policies and practices. The members of the Corporate Governance Committee are Allen J. Palmiere (Chairman), M. Norman Anderson, and James W. Aschroft, a majority of who are unrelated directors under the Guidelines.
		The Environmental, Health and Safety Committee meets at least once per year or more frequently as required and oversees the development and implementation of policies and best practices of the Company relating to environmental and health and safety issues in order to ensure compliance with applicable laws and to ensure the safety of its employees. The members of the Safety and Environment Committee are James W. Ashcroft (Chairman), Allen J. Palmiere and Richard Brissenden, each of whom are unrelated directors under the Guidelines.
		Other matters are considered by the full Board. As required by applicable law or when circumstances warrant, the Board may strike ad hoc committees.
10.	The board should expressly assume responsibility for, or assign to a committee the general responsibility for, the approach to corporate governance issues	The Board has assigned responsibility for the Company's approach to corporate governance issues to the Corporate Governance and Nominating Committee. On February 2, 2005, the Board adopted Board and Committee Charters and policies, the Code of Business Conduct and Ethics, the Whistleblower Policy, the Role Statement of the Chief Executive Officer. (Prior to December 24, 2005, the Common Shares were listed on the TSXV.) Once the Instrument and Policy are final, the Corporate Governance and Nominating Committee will meet and will review the Company's corporate governance practices to ensure that the Company's corporate governance practices are appropriate taking into account the recommendations in the Instrument and the Policy and given the Company's size and resources and other applicable laws.
11.	a) Define limits to management's responsibilities by developing mandates for:
	(i) the board	A Charter of the Board of Directors, setting out the responsibilities of the Board and its Committees, was approved on February 2, 2005. In addition to the Charter of the Board of Directors, the corporate standard of care is set out in the governing corporate legislation of the Company, the Business Corporations Act (Ontario) (the "OBCA"). The OBCA indicates that each director and officer of a company governed by it, in exercising his or her powers and discharging his or her duties, shall act honestly and in good faith with a view to the best interests of the corporation and exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. The Board explicitly assumes responsibility for stewardship of the Company, including the integrity of the Company's internal control and management information systems.

TSX Corporate Governance Guidelines		Corporate Governance Practices of the Company
		Although the Board supervises, directs and oversees the business and affairs of the Company, it delegates the day-to-day management to others, while reserving the ability to intervene in management decisions and to exercise final judgment on any matter.
		In order to carry out the foregoing responsibilities, the Board meets as required by circumstances.
		The Board expects management to operate the business in accordance with the mandate referred to above and to maximize shareholder value, consistent with public and employee safety and the other objectives referred to above. The results of the management activities are reviewed continually by the Board.
	(ii) the Chief Executive Officer	The responsibilities of the Chief Executive Officer are set out in the "Role Statement of the CEO", approved on February 2, 2005 and the general objectives of the Chief Executive Officer are set by the Board who is charged with the general mandate to implement the approved corporate objectives and the strategic business plan of the Company (see Item 1(a) above).
	b) Board should approve Chief Executive Officer's corporate objectives	See Item 11(a)(ii) above.
12.	Implement structures and procedures to ensure the Board can function independently of management	The Board has appointed a Chairman, other than the Chief Executive Officer. The Charter of the Board provides for regular meetings without management being present.
13.	Establish an Audit Committee, composed only of outside directors, with a specifically defined mandate	See Item 9 above.
14.	Implement a system to enable individual directors to engage outside advisors, at the corporation's expense	Each committee of the Board and, in appropriate circumstances and with the approval of the Board, an individual director, may engage outside advisors, independent of management, at the expense of the Company.

Certificates for such Shares shall be issued and delivered to the Optionee within a reasonable period of time following the receipt of such notice and payment.

6.2 (a) The exercise price for Shares purchased under an Option shall be paid in full to the Corporation by delivery of consideration in an amount equal to the Option Price.

(b): The Corporation may permit an Optionee to elect to pay the Option Price by authorizing a third party to sell Shares (or a sufficient portion of such Shares) acquired upon exercise of the Option and remit to the Corporation a sufficient portion of the sale proceeds to pay the entire Option Price and any tax withholding resulting from such exercise.
(c): In addition, the Option Price for Shares purchased under an Option may be paid, either singly or in combination with one or more of the alternative forms of payment authorized by this Section 6.2, by such other consideration as the Board may permit.

(c): the receipt from the Optionee of such representations, agreements and undertakings, including as to future dealings in such Shares, as the Corporation or its counsel reasonably determines to be necessary or advisable in order to safeguard against the violation of the securities laws of any jurisdiction.

In this connection the Corporation shall, to the extent necessary, take all reasonable steps to obtain such approvals, registrations and qualifications as may be necessary for the issuance of such Shares in compliance with applicable securities laws and for the listing of such Shares on the Exchange.

Notwithstanding the foregoing, in the event the Optionee ceases to be an Eligible Person by reason of his or her retirement, then, such Optionee shall have the right, at any time or from time to time during the remainder of the term of the Option, to purchase such number of Shares that remain subject to the Option, provided that any Options held by an Optionee at the time of his or her retirement, shall remain subject to Section 5.4(b) of the Plan. For the purposes of this section, the term "retirement" shall mean the normal retirement date for the Eligible Person or such other adjusted date as may be agreed upon by the Eligible Person and the Corporation.

7.2 If, before the expiry of an Option in accordance with the terms thereof, the employment of the Optionee with the Corporation or with any Subsidiary shall terminate, in either case by reason of the death of the Optionee, such Option may, subject to the terms thereof and any other terms of the Plan, be exercised by the legal representative(s) of the estate of the Optionee at any time during the first year following the death of the Optionee (but prior to the expiry of the Option in accordance with the terms thereof) but only to the extent that the Optionee was entitled to exercise such Option at the date of the termination of the Optionee's employment.

(iii): the addition of any form of financial assistance;
(iv): any amendment to a financial assistance provision which is more favourable to participants;

(ix): discontinuance of the Plan; and
(viii): and any other amendments that may lead to significant or unreasonable dilution in the Corporation's outstanding securities or may provide, additional benefits to Eligible Persons, especially insiders of the Corporation, at the expense of the Corporation and its existing shareholders.

10.2 Nothing in the Plan or any Option shall confer upon an Optionee any right to continue in the employ of the Corporation or any Subsidiary or affect in any way the right of the Corporation or any Subsidiary to terminate the Optionee's employment at any time; nor shall anything in the Plan or any Option be deemed or construed to constitute an agreement, or an expression of intent, on the part of the Corporation or any Subsidiary to extend the employment of any Optionee beyond the time which the Optionee would normally be retired pursuant to the provisions of any present or future retirement plan of the Corporation or any Subsidiary, or beyond the time at which the Optionee would otherwise be retired pursuant to the provisions of any contract of employment with the Corporation or any Subsidiary.

10.3 To the extent required by law or regulatory policy or as may be necessary to allow Shares issued on exercise of an Option to be free of resale restrictions, the Corporation shall report the grant, exercise or termination of the Option to the Exchange and the appropriate securities regulatory authorities.

10.4 The Corporation may refuse to honour the exercise of an Option unless the Optionee pays to the Corporation the amount of any withholding taxes that the Corporation is required to withhold with respect to the grant or exercise of any Option. Subject to the Plan and applicable law, the Board may, in its sole discretion, permit the Optionee to satisfy withholding obligations in whole or in part, by paying cash or by electing to have the Corporation withhold Shares in such amounts as are equivalent to the Market Price in order to satisfy the withholding obligation. The Corporation shall have the right to withhold from any Shares issuable pursuant to an Option or from any cash amounts otherwise due or to become due from the Corporation to the Optionee an amount equal to such taxes, and such withheld Shares shall be cancelled if required by any applicable law or regulatory authority. The Corporation may also deduct from any Option any other amounts due from the Optionee to the Corporation. For the purposes of this section 10.4, all references to the Corporation shall be deemed to include references to a Subsidiary where the context permits.

ARTICLE 11

The directors in their discretion may submit any contract, act or transaction for approval, ratification or confirmation at any annual meeting of the shareholders or at any special meeting of the shareholders called for the purpose of considering the same and any contract, act or transaction that shall be approved, ratified or confirmed by resolution passed by a majority of the votes cast at any such meeting (unless any different or additional requirement is imposed by the Act or by the Corporation's articles or any other by-law) shall be as valid and as binding upon the Corporation and upon all the shareholders as though it had been approved, ratified and/or confirmed by every shareholder of the Corporation.

PART EIGHT

8.01 Allotment

Subject to the Act, the articles of the Corporation and any unanimous shareholder agreement, the directors may from time to time allot, or grant options to purchase, the whole or any part of the authorized and unissued shares of the Corporation at such times and to such persons and for such consideration as the directors may determine, provided that no share shall be issued until it is fully paid as provided by the Act.

8.02 Commissions

The directors may from time to time authorize the Corporation to pay a reasonable commission to any person in consideration of his purchasing or agreeing to purchase shares of the Corporation, whether from the Corporation or from any other person, or procuring or agreeing to procure purchasers for any such shares.

The directors may from time to time appoint a registrar to maintain the securities register and a transfer agent to maintain the register of transfers and may also appoint one or more branch registrars to maintain branch securities registers and one or more branch transfer agents to maintain branch registers of transfers, but one person may be appointed both registrar and transfer agent. The directors may at any time terminate any such appointment.

8.04 Share Certificates

Every holder of one or more shares of the Corporation shall be entitled, at his option, to a share certificate, or to a non-transferrable written acknowledgement of his right to obtain a share certificate, stating the number and class or series of shares held by him as shown on the securities register. Share certificates and acknowledgements of a shareholder's right to a share certificate shall be in such form as the directors shall from time to time approve. Any share certificate shall be signed in accordance with section 2.04; it need not be under the corporate seal. The signature of one of the signing officers may be printed or mechanically reproduced in facsimile upon share certificates; the other officer must sign manually. Every such facsimile signature shall for all purposes be deemed to be a signature binding upon the Corporation. Unless the directors otherwise determine, certificates representing shares in respect of which a transfer agent or registrar, as the case may be, has been appointed shall not be valid unless countersigned manually by or on behalf of such transfer agent or registrar. In the case of share certificates which are not valid unless countersigned manually by or on behalf of a transfer agent or registrar, the signature of both signing officers may be printed or mechanically reproduced in facsimile upon share certificates and every such facsimile signature shall for all purposes be deemed to be a signature binding upon the Corporation. Notwithstanding any change in the persons holding office between the time of signing and the issuance of any certificate, and notwithstanding that a person may not have held office at the date of issuance of such certificate, any such certificate so signed shall be valid and binding upon the Corporation.

8.05 Registration of Transfer

Subject to the Act, a transfer of shares shall not be registered in a securities register except upon presentation of the certificate representing such shares with a transfer endorsed thereon, or delivered therewith, duly executed by the registered holder or by his attorney, fiduciary or agent duly appointed, together with such reasonable assurance that the endorsement is genuine and effective as the directors may from time to time prescribe, upon payment of all applicable taxes and any reasonable fees prescribed by the directors, upon compliance with such restrictions on transfer as are authorized by the articles, and upon satisfaction of any lien referred to in section 8.10.

8.06 Non-Recognition of Trusts

Subject to the Act, the Corporation may treat the registered holder of any share as the person exclusively entitled to vote, to receive notices, to receive any dividend or other payments in respect of the share, and otherwise to exercise all the rights and powers of an owner of the share.

8.07 Joint Shareholders

If two or more persons are registered as joint holders of any share, the Corporation shall not be bound to issue more than one certificate in respect thereof, and delivery of such certificate to one of such persons shall be sufficient delivery to all of them. Any one of such persons may give effectual receipts for the certificate issued in respect thereof or for any dividend, bonus, return of capital or other money payable or warrant issuable in respect of such share.

8.08 Deceased Shareholders

In the event of the death of a holder, or of one of the joint holders, of any share, the Corporation shall not be required to make any entry in the securities register in respect thereof or to make dividends or other payments in respect thereon except upon production of all such documents as may be required by law and upon compliance with the reasonable requirements of the Corporation and its transfer agents.

8.09 Replacement of Share Certificates

The directors or any officer or agent designated by the directors may in their or his discretion direct the issue of a new share certificate in lieu of and upon cancellation of a share certificate that has been mutilated or in substitution for a share certificate claimed to have been lost, destroyed or wrongfully taken on payment of such reasonable fee, and on such terms as to indemnity, reimbursement of expenses and evidence of loss and of title as the directors may from time to time prescribe, whether generally or in any particular case.

8.10 Lien for Indebtedness

If the articles provide that the Corporation shall have a lien on shares registered in the name of a shareholder indebted to the Corporation, such lien may be enforced, subject to the articles and to any unanimous shareholder agreement, by the sale of the shares thereby affected or by any other action, suit, remedy or proceeding authorized or permitted by law or by equity and, pending such enforcement, may refuse to register a transfer of the whole or any part of such shares.

PART NINE

DIVIDENDS AND RIGHTS

9.01 Dividends

Subject to the Act, the directors may from time to time declare dividends payable to the shareholders according to their respective rights and interests in the Corporation. Dividends may be paid in money or property or by issuing fully paid shares of the Corporation.

A dividend payable in money shall be paid by cheque drawn on the Corporation's bankers or one of them to the order of each registered holder of shares of the class or series in respect of which it has been declared and mailed by prepaid ordinary mail to such registered holder at his recorded address, unless such holder otherwise directs. In the case of joint holders the cheque shall, unless such joint holders otherwise direct, be made payable to the order of all of such joint holders and mailed to them at their recorded address. The mailing of such cheque as aforesaid, unless the same is not paid on due presentation, shall satisfy and discharge the liability for the dividend to the extent of the sum represented thereby plus the amount of any tax which the Corporation is required to and does withhold.

9.03 Non-Receipt of Cheques

In the event of non-receipt of any dividend cheque by the person to whom it is sent as aforesaid, the Corporation shall issue to such person a replacement cheque for a like amount on such terms as to indemnity, reimbursement of expenses and evidence of non-receipt and of title as the directors may from time to time prescribe, whether generally or in any particular case.

9.04 Record Date for Dividends and Rights

The directors may fix in advance a date, preceding by not more than 50 days the date for the payment of any dividend or the date for the issue of any warrant or other evidence of right to subscribe for securities of the Corporation, as a record date for the determination of the persons entitled to receive payment for such dividend or to exercise the right to subscribe for such securities, and notice of any such record date shall be given not less than 7 days before such record date by newspaper advertisement in the manner provided in the Act unless notice of the record date is waived in writing by every holder of a share of a class or series affected whose name is set out in the securities register at the close of business on the day the directors fix the record date. If no record date is so fixed, the record date for the determination of the persons entitled to receive payment of any dividend or to exercise the right to subscribe for securities of the Corporation shall be at the close of business on the day on which the resolution relating to such dividend or right to subscribe is passed by the directors.

10.07 Meetings without Notice

A meeting of shareholders may be held without notice at any time and place permitted by the Act (a) if all the shareholders entitled to vote thereat are present in person or represented by proxy or if those not present or represented by proxy waive notice of or otherwise consent to such meeting being held, and (b) if the auditors and the directors are present or waive notice of or otherwise consent to such meeting being held, provided that such shareholders, auditors or directors present are not attending for the express purpose of objecting to the transaction of any business on the grounds that the meeting is not lawfully called. At such a meeting, any business may be transacted which the Corporation at a meeting of shareholders may transact. If the meeting is held at a place outside Canada, shareholders not present or represented by proxy, but who have waived notice of or otherwise consented to such meeting, shall also be deemed to have consented to the meeting being held at such place.

If the secretary of the Corporation is absent, the chairman shall appoint some person, who need not be a shareholder, to act as secretary of the meeting. If desired, one or more scrutineers, who need not be shareholders, may be appointed by a resolution or by the chairman with the consent of the meeting.

10.09 Persons Entitled to be Present

The only persons entitled to be present at a meeting of shareholders shall be those entitled to vote thereat, the directors and auditors of the Corporation and others who, although not entitled to vote, are entitled or required under any provision of the Act or the articles or by-laws to be present at the meeting.

10.10 Quorum

A quorum for the transaction of business at any meeting of shareholders shall be 2 persons present in person, each being a shareholder entitled to vote thereat or a duly appointed proxy or proxyholder for an absent shareholder so entitled, holding or representing in the aggregate not less than 10% of the issued shares of the Corporation enjoying voting rights at such meeting.

10.11 Right to Vote

Subject to the provisions of the Act as to representatives of any other body corporate which is a shareholder of the Corporation and to section 10.12, every person named in the list referred to in section 10.05 shall be entitled to vote the shares shown thereon opposite his name at the meeting to which such list relates, except to the extent that (a) where the Corporation has fixed a record date in respect of such meeting, such person has transferred any of his shares after such record date, or, where the Corporation has not fixed a record date in respect of such meeting, such person has transferred any of his shares after the date on which such list is prepared, and (b) the transferee, having produced properly endorsed certificates evidencing such shares or having otherwise established that he owns such shares, has demanded not later than 10 days before the meeting that his name be included in such list. In any such excepted case, the transferee shall be entitled to vote the transferred shares at such meeting.

10.12 Proxyholders and Representatives

Every shareholder entitled to vote at a meeting of shareholders may appoint a proxyholder, or one or more alternate proxyholders, to attend and act as his representative at the meeting in the manner and to the extent authorized and with the authority conferred by the proxy. A proxy shall be in writing executed by the shareholder or his attorney and shall conform with the requirements of the Act. Alternatively, every such shareholder which is a body corporate or association may authorize by resolution of its directors or governing body an individual to represent it at a meeting of shareholders and such individual may exercise on the shareholder's behalf all the powers it could exercise if it were an individual shareholder. The authority of such an individual shall be established by depositing with the Corporation a certified copy of such resolution, or in such other manner as may be satisfactory to the secretary of the Corporation or the chairman of the meeting. Any such proxyholder or representative need not be a shareholder. A proxy shall be in written or printed format or a format generated by telephonic or electronic means and becomes a proxy when completed and signed in writing or by electronic signature by the shareholder or his attorney authorized by a document that is signed in writing or by electronic signature or, if the shareholder is a body corporate, by an officer or attorney thereof, duly authorized. If a proxy or document authorizing an attorney is signed by electronic signature, the means of electronic signature shall permit a reliable determination that the proxy or document was created or communicated by or on behalf of the shareholder or attorney, as the case may be.

10.13 Time for Deposit of Proxies

The directors may specify in a notice calling a meeting of shareholders a time, preceding the time of such meeting by not more than 48 hours exclusive of non-business days, before which time proxies to be used at such meeting must be deposited. A proxy shall be acted upon only if, prior to the time so specified, it shall have been deposited with the Corporation or an agent thereof specified in such notice or, if no such time is specified in such notice, it has been received by the secretary of the Corporation or by the chairman of the meeting or any adjournment thereof prior to the time of voting.

10.14 Joint Shareholders

If two or more persons hold shares jointly, any of them present in person or represented by proxy at a meeting of shareholders may, in the absence of the other or others, vote the shares; but if two or more of those persons are present in person or represented by proxy, they shall vote together as one on the shares jointly held by them.

10.15 Votes to Govern

At any meeting of shareholders every question shall, unless otherwise required by the articles or by-laws or by law, be determined by the majority of the votes cast on the question. In case of an equality of votes either upon a show of hand or upon a poll, the chairman of the meeting shall not be entitled to a second or casting vote.

10.16 Show of Hands

Subject to the Act, any question at a meeting of shareholders shall be decided by a show of hands unless a ballot thereon is required or demanded as provided in section 10.17. Upon a show of hands every person who is present and entitled to vote shall have one vote. Whenever a vote by show of hands shall have been taken upon a question, unless a ballot thereon is so required or demanded, a declaration by the chairman of the meeting that the vote upon the question has been carried or carried by a particular majority or not carried and an entry to that effect in the minutes of the meeting shall be prima facie evidence of the fact without proof of the number or proportion of the votes recorded in favour of or against any resolution or other proceeding in respect of the said question, and the result of the vote so taken shall be the decision of the shareholders upon the said question. For the purpose of this section, if at any meeting the Corporation has made available to shareholders the means to vote electronically, any vote made electronically shall be included in tallying any votes by show of hands.

10.17 Ballots

On any question proposed for consideration at a meeting of shareholders, and whether or not a show of hands has been taken thereon, the chairman may require a ballot or any person who is present and entitled to vote at the meeting may require or demand a ballot. A ballot so required or demanded shall be taken in such manner as the chairman shall direct. A requirement or demand for a ballot may be withdrawn at any time prior to the taking of the ballot. If a ballot is taken each person present shall be entitled, in respect of the shares which he is entitled to vote at the meeting upon the question, to that number of votes provided by the Act or the articles, and the result of the ballot so taken shall be the decision of the shareholders upon the said question.

10.18 Adjournment

The chairman at a meeting of shareholders may, with the consent of the meeting and subject to such conditions as the meeting may decide, adjourn the meeting from time to time and from place to place. If a meeting of shareholders is adjourned for less than 30 days, it shall not be necessary to give notice of the adjourned meeting, other than by announcement at the earliest meeting that is adjourned. Subject to the Act, if a meeting of shareholders is adjourned by one or more adjournments for an aggregate of 30 days or more, notice of the adjourned meeting shall be given as for an original meeting.

10.19 Resolution in Writing

A resolution in writing signed by all the shareholders entitled to vote on that resolution at a meeting of shareholders is as valid as if it had been passed at a meeting of the shareholders unless a written statement with respect to the subject matter of the resolution is submitted by a director or the auditors in accordance with the Act.
