The execution of this Letter of Transmittal or the making of a book-entry transfer in accordance with Section 3 of the Offer, “Manner of Acceptance - Acceptance by Book-Entry Transfer”, irrevocably appoints each officer of the Offeror and any other person designated by the Offeror in writing as the true and lawful agent, attorney and attorney-in-fact and proxy of the holder of the Deposited Shares deposited pursuant to the Offer and purchased by the Offeror (the “Purchased Shares”), and with respect to any and all Distributions thereon which may be declared, paid, accrued, issued, distributed, made or transferred on or in respect of the Purchased Shares or any of them after February 11, 2014 except as otherwise indicated in Section 10 of the Offer, “Changes in Capitalization, Dividends, Distributions and Liens”.

An Augusta Shareholder who executes this Letter of Transmittal (or who deposits Augusta Shares by making a book-entry transfer) also agrees, effective on and after the date the Offeror takes up and pays for Purchased Shares, not to vote any of the Purchased Shares or Distributions at any meeting (whether annual, special or otherwise or any adjournments or postponements thereof, including, without limitation, any meeting to consider a Subsequent Acquisition Transaction) of holders of relevant securities of Augusta and not to exercise any or all of the other rights or privileges attached to the Purchased Shares or Distributions and agrees to execute and deliver to the Offeror any and all instruments of proxy, authorizations or consents, in form and on terms satisfactory to the Offeror, in respect of all or any of the Purchased Shares or Distributions, and to designate in such instruments of proxy the person or persons specified by the Offeror as the proxy or the proxy nominee or nominees of the holder in respect of the Purchased Shares or Distributions. Upon such appointment, all prior proxies and other authorizations (including, without limitation, all appointments of any agent, attorney or attorney-in-fact) or consents given by the holder of such Purchased Shares or Distributions with respect thereto shall be revoked and no subsequent proxies or other authorizations or consents may be given by such person with respect thereto.

The acceptance of the Offer pursuant to the procedures described herein constitute a binding agreement between the depositing Augusta Shareholder and the Offeror, effective immediately following the time at which the Offeror takes up Augusta Shares deposited by such Augusta Shareholder, upon the terms and subject to the conditions of the Offer, including the depositing Augusta Shareholder’s representation and warranty that: (i) such person has full power and authority to deposit, sell,

assign and transfer the Augusta Shares (and any Distributions) being deposited and all interests therein and has not sold, assigned or transferred or agreed to sell, assign or transfer any of such Augusta Shares or Distributions (or interests therein) to any other person, (ii) such Augusta Shareholder depositing the Augusta Shares (and any Distributions), or on whose behalf such Augusta Shares (and any Distributions) are being deposited, has good title to and is the beneficial owner of the Augusta Shares (and any Distributions) being deposited within the meaning of applicable Laws, (iii) the deposit of such Augusta Shares (and any Distributions) complies with applicable Laws, and (iv) when such deposited Augusta Shares (and any Distributions) are taken up and paid for by the Offeror, the Offeror will acquire good title thereto free and clear of all liens, restrictions, charges, encumbrances, claims, adverse interests, equities and rights of other persons.

If, prior to the Expiry Time, the consideration being offered for the Augusta Shares under the Offer is increased, the increased consideration will be paid to all depositing Augusta Shareholders whose Augusta Shares are taken up under the Offer, whether or not taken up before or after such variation. The undersigned recognizes that, subject to the limitations set out in the Offer and Circular, the Offeror reserves the right in its sole discretion, at any time and from time to time, to extend, withdraw or terminate the Offer and to not take up and pay for any Augusta Shares deposited under the Offer unless each of the conditions of the Offer is satisfied or waived at or prior to the Expiry Time. See Section 4 of the Offer, “Conditions of the Offer”.

An Augusta Shareholder accepting the Offer covenants to execute, upon request of the Offeror, any additional documents, transfers and other assurances as may be necessary or desirable to complete the sale, assignment and transfer of the Purchased Shares or Distributions to the Offeror and acknowledges that all authority therein conferred or agreed to be conferred may be exercised during any subsequent legal incapacity of such holder and shall, to the extent permitted by Law, survive the death or incapacity, bankruptcy or insolvency of the Augusta Shareholder and all obligations of the Augusta Shareholder therein shall be binding upon the heirs, executors, administrators, attorneys, personal representatives, successors and assigns of such Augusta Shareholder.

Unless otherwise required or permitted by applicable Laws, any Augusta Shares deposited in acceptance of the Offer may be withdrawn by or on behalf of the depositing Augusta Shareholder: (a) at any time before the Deposited Shares have been taken up by the Offeror pursuant to the Offer; (b) if the Deposited Shares have not been paid for by the Offeror within three business days after having been taken up; or (c) at any time before the expiration of ten days from the date upon which either: (i) a notice of change relating to a change that has occurred in the information contained in the Offer or the Circular, as amended from time to time, that would reasonably be expected to affect the decision of an Augusta Shareholder to accept or reject the Offer (other than a change that is not within the control of the Offeror or of an affiliate of the Offeror, unless it is a change in a material fact relating to the Hudbay Shares), in the event that such change occurs before the Expiry Time or after the Expiry Time but before the expiry of all rights of withdrawal in respect of the Offer; or (ii) a notice of variation concerning a variation in the terms of the Offer (other than a variation consisting solely of an increase in the consideration offered for the Augusta Shares where the Expiry Time is not extended for more than ten days) is mailed, delivered or otherwise properly communicated to the Depositary (subject to abridgement of that period pursuant to such order or orders or other forms of relief as may be granted by applicable courts or securities regulatory authorities) and only if such Deposited Shares have not been taken up by the Offeror in advance of the receipt of such communication by the Depositary.

Withdrawals of Deposited Shares must be effected by notice of withdrawal made by or on behalf of the depositing Augusta Shareholder in writing and must be actually received by the Depositary at the place of deposit before such Deposited Shares are taken up and paid for.

Any signature in a notice of withdrawal must be guaranteed by an Eligible Institution in the same manner as in this Letter of Transmittal (as described in the instructions and rules set out therein), except in the case of Augusta Shares deposited for the account of an Eligible Institution.

The Offeror will pay for Augusta Shares validly deposited under the Offer and not withdrawn by providing the Depositary with sufficient Hudbay Shares for transmittal to depositing Augusta Shareholders. Under no circumstances will interest accrue or any amount be paid by the Offeror or the Depositary to persons depositing Augusta Shares on the purchase price of Augusta Shares purchased by the Offeror, regardless of any delay in making such deliveries.

The Depositary will act as the agent of persons who have deposited Augusta Shares in acceptance of the Offer for the purposes of receiving payment from the Offeror and transmitting such payment to such persons, and receipt of payment by the Depositary will be deemed to constitute receipt of payment by persons depositing Augusta Shares under the Offer.

Settlement with each Augusta Shareholder who has deposited (and not properly withdrawn) Augusta Shares under the Offer will be made by the Depositary delivering or causing to be delivered certificates representing Hudbay Shares, in the amounts to which the person depositing Augusta Shares is entitled. Unless otherwise directed by this Letter of Transmittal, the certificates will be issued in the name of the registered holder of the Augusta Shares so deposited. Unless the person depositing the Augusta Shares instructs the Depositary to hold the certificates for pick-up by checking the appropriate box below, the certificates will be forwarded by first class mail to such person at the address specified below.

certificates will be sent to the address of the registered holder as shown on the securities register maintained by or on behalf of Augusta.

For purposes of this Letter of Transmittal, a “U.S. Holder” means a beneficial owner of Augusta Shares that is (i) a citizen or individual resident of the U.S. for U.S. federal income tax purposes; (ii) a corporation (or an entity classified as a corporation for U.S. federal tax purposes) created or organized in or under the Laws of the U.S. or any political subdivision thereof; (iii) an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust if (A) a U.S. court is able to exercise primary supervision over its administration and one or more U.S. persons, within the meaning of Section 7701(a)(30) of the Code, have authority to control all of its substantial decisions or (B) it has properly elected under applicable Treasury Regulations to continue to be treated as a U.S. person.

United States federal income tax law generally requires a U.S. Holder who receives cash in exchange for Augusta Shares to provide the Depositary with its correct Taxpayer Identification Number (“TIN”), which, in the case of a U.S. Holder who is an individual, generally is the individual’s social security number. If the Depositary is not provided with the correct TIN or an adequate basis for an exemption, such holder may be subject to penalties imposed by the Internal Revenue Service and backup withholding in an amount equal to 28% of the gross proceeds of any payment received hereunder. If withholding results in an overpayment of taxes, a refund may be obtained by filing a U.S. tax return.

To prevent backup withholding, each U.S. Holder must provide its correct TIN by completing the “Substitute Form W-9” set forth in this document, which requires the Augusta shareholder to certify under penalties of perjury, (1) that the TIN provided is correct (or that such holder is awaiting a TIN), (2) that (i) the holder is exempt from backup withholding; (ii) the holder has not been notified by the Internal Revenue Service that he is subject to backup withholding as a result of a failure to report all interest or dividends; or (iii) the Internal Revenue Service has notified the holder that he is no longer subject to backup withholding; (3) that the holder is a U.S. person for U.S. federal income tax purposes (including a U.S. resident alien); and (4) that the FATCA code(s) entered on this form (if any) indicating that the holder is exempt from FATCA reporting is correct.

Exempt holders (including, among others, all corporations) are not subject to backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt holder must enter its correct TIN in Part 1 of Substitute Form W-9, write “Exempt” in Part 2 of such form, and sign and date the form. See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 (the “W-9 Guidelines”) for additional instructions.

If Augusta Shares are held in more than one name or are not in the name of the actual owner, consult the enclosed W-9 Guidelines for information on which TIN to report. If a U.S. Holder does not have a TIN, such holder should: (i) consult the enclosed W-9 Guidelines for instructions on applying for a TIN, (ii) write “Applied For” in the space for the TIN in Part 1 of the Substitute Form W-9, and (iii) sign and date the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number set forth in this document. In such case, the Depositary may withhold 28% of the gross proceeds of any payment made to such holder prior to the time a properly certified TIN is provided to the Depositary, and if the Depositary is not provided with a TIN within sixty (60) days, such amounts will be paid over to the Internal Revenue Service.

If an Augusta shareholder has a U.S. address, but is not considered a U.S. person for U.S. federal income tax purposes, such holder is required to submit an appropriate and properly completed IRS Form W-8 Certificate of Foreign Status, signed under penalties of perjury. Such appropriate IRS Form W-8 may be obtained from the Depositary.

AN AUGUSTA SHAREHOLDER WHO FAILS TO PROPERLY COMPLETE THE SUBSTITUTE FORM W-9 SET FORTH IN THIS LETTER OF TRANSMITTAL OR, IF APPLICABLE, THE APPROPRIATE IRS FORM W-8 MAY BE SUBJECT TO BACKUP WITHHOLDING OF 28% OF THE GROSS PROCEEDS OF ANY PAYMENTS MADE TO SUCH HOLDER PURSUANT TO THE OFFER. BACKUP WITHHOLDING IS NOT AN ADDITIONAL TAX. RATHER, THE TAX LIABILITY OF PERSONS SUBJECT TO BACKUP WITHHOLDING WILL BE REDUCED BY THE AMOUNT OF TAX WITHHELD. IF WITHHOLDING RESULTS IN AN OVERPAYMENT OF TAXES, A REFUND MAY BE OBTAINED BY FILING A TAX RETURN WITH THE IRS. THE DEPOSITARY CANNOT REFUND AMOUNTS WITHHELD BY REASON OF BACKUP WITHHOLDING.

TO ENSURE COMPLIANCE WITH U.S. TREASURY DEPARTMENT CIRCULAR 230, U.S. HOLDERS ARE HEREBY NOTIFIED THAT: (A) ANY DISCUSSION OF U.S. FEDERAL TAX ISSUES IN THIS DOCUMENT IS NOT INTENDED OR WRITTEN BY OFFEROR TO BE USED, AND CANNOT BE USED, BY ANY TAXPAYER FOR THE PURPOSE OF AVOIDING PENALTIES THAT MAY BE IMPOSED ON THE TAXPAYER UNDER THE U.S. INTERNAL REVENUE CODE; (B) THESE DISCUSSIONS WERE WRITTEN IN CONNECTION WITH THE PROMOTION OR MARKETING OF THE OFFER; AND (C) EACH TAXPAYER SHOULD SEEK ADVICE FROM AN INDEPENDENT TAX ADVISOR BASED ON ITS PARTICULAR CIRCUMSTANCES.

8. Requests for Assistance or Additional Copies. Questions or requests for assistance may be directed to the Information Agent or the Depositary at the addresses and telephone numbers set forth below. Requests for additional copies of the Offer and Circular, this Letter of Transmittal and the Notice of Guaranteed Delivery may be directed to the Information Agent or the Depositary and copies will be furnished promptly at the Offeror’s expense. Augusta Shareholders may also contact their brokers, investment dealers, banks, trust companies or other nominees for assistance concerning the Offer.

9. Lost, Destroyed or Stolen Certificates. If any Augusta Share Certificate has been lost, destroyed or stolen, this Letter of Transmittal should be completed as fully as possible and forwarded, together with a letter describing the loss, theft or destruction to the Depositary at its office in Toronto, Ontario, Canada. The Depositary will forward such letter to the transfer agent for the Augusta Shares so that the transfer agent may provide replacement instructions. Please ensure that you provide your telephone number so that the Depositary or the transfer agent for the Augusta Share Certificate may contact you. If your Augusta Share Certificate has been lost, stolen or destroyed, you must take the foregoing action sufficiently in advance of the Expiry Time in order to obtain a replacement certificate in sufficient time to permit the replacement certificate to be tendered to the Offer prior to the Expiry Time.

10. Miscellaneous.

a) Augusta Shareholders will not be required to pay any fee or commission if they accept the Offer by depositing their Augusta Shares directly with the Depositary or if they make use of the services of a Soliciting Dealer to accept the Offer. However an investment advisor, stock broker, bank, trust company or other nominee that is not a Soliciting Dealer and through whom an Augusta Shareholder holds Augusta Shares may charge a fee to tender any such Augusta Shares on behalf of the Augusta Shareholder. Augusta Shareholders should consult such nominee to determine whether any charges will apply. Augusta Shareholders should also contact the Depositary, the Information Agent, their investment advisor, stockbroker, bank, trust company or other nominee for assistance in accepting the Offer and in depositing the Augusta Shares with the Depositary.

b) The Offeror will not issue fractional Hudbay Shares. Instead, where the aggregate number of Hudbay Shares to be issued under the Offer to an Augusta Shareholder would result in a fraction of a Hudbay Share being issuable, the number of Hudbay Shares to be received by such Augusta Shareholder will be rounded to the nearest whole Hudbay Share.

c) The Offeror will not pay any fees or commissions to any broker or investment dealer or any other person for soliciting deposits of Augusta Shares, if applicable, pursuant to the Offer except as otherwise contemplated by the Offer and Circular (other than to the Dealer Manager and members of the Soliciting Dealer Group).

e) No alternative, conditional or contingent deposits will be accepted and no fractional Augusta Shares will be purchased. All Augusta Shareholders by execution of this Letter of Transmittal, waive any right to receive any notice of the acceptance of Augusta Shares for payment, except as required by applicable laws.

f) Before completing this Letter of Transmittal, you are urged to read the accompanying Offer and Circular and the Notice of Guaranteed Delivery and all other documents related to the Offer.

g) All questions as to the validity, form, eligibility (including, without limitation, timely receipt) and acceptance of any Augusta Shares deposited under the Offer will be determined by the Offeror in their sole discretion. Augusta Shareholders agree that such determination will be final and binding. The Offeror reserves the right to reject any and all deposits that they determines not to be in proper form or that may be unlawful to accept under the Laws of any jurisdiction. The Offeror reserve the right to waive any defects or irregularities in the deposit of any Augusta Shares. There shall be no duty or obligation of the Offeror, the Depositary or any other person to give notice of any defects or irregularities in any deposit and no liability shall be incurred or suffered by any of them for failure to give any such notice. The Offeror’s interpretation of the terms and conditions of the Offer, this Letter of Transmittal, the Notice of Guaranteed Delivery and any other related documents will be final and binding. The Offeror reserves the right to permit the Offer to be accepted in a manner other than that set out in the Offer and Circular.

h) If the space on this Letter of Transmittal is insufficient to list all Augusta Share Certificates for the deposited Augusta Shares additional certificate numbers and the number of deposited Augusta Shares may be included on a separate signed list affixed to this Letter of Transmittal.

i) The Offer and Circular and any agreement resulting from the acceptance of the Offer will be governed by and construed in accordance with and governed by the laws of the Province of Ontario and the Laws of Canada applicable therein. Each party to an agreement resulting from the acceptance of the Offer unconditionally and irrevocably attorns to the exclusive jurisdiction of the courts of the Province of Ontario and the courts of appeal therefrom.

j) The Offeror, in its sole discretion, shall determine all questions relating to the interpretation of the Offer and Circular, this Letter of Transmittal and the Notice of Guaranteed Delivery, the validity (including time of receipt) of any acceptance of the Offer and any withdrawal of Augusta Shares, including, without limitation, the satisfaction or non-satisfaction of any condition, the validity, time and effect of any deposit of Augusta Shares or notice of withdrawal of Augusta Shares and the due completion and execution of the Letter of Transmittal or Notice of Guaranteed Delivery. The Offeror’s determination of such matters shall be final and binding for all purposes. The Offeror reserves the right to waive any defect in acceptance with respect to any particular Augusta Share or any particular Augusta Shareholder or to permit the Offer to be accepted in any manner other than as set out in the Offer. There will be no duty or obligation on the Offeror or the Depositary to give notice of any defect or irregularity in any deposit or notice of withdrawal, and no liability shall be incurred by any of them for failure to give any such notification.

How to Get a TIN

To apply for an SSN, obtain Form SS-5, Application for a Social Security Card, at the local office of the Social Security Administration or get this form on-line at www.ssa.gov/online/ss-5.pdf. You may also get this form by calling 1-800-772-1213. You can apply for an EIN online by accessing the IRS website at www.irs.gov/businesses and clicking on Employer ID Numbers under Business Topics. Use Form SS-4, Application for Employer Identification Number, to apply for an EIN. You can get Form SS-4 from the IRS by calling 1-800-TAX-FORM (1-800-829-3676) or from the IRS web site at www.irs.gov.

If you do not have a TIN, write “Applied For” in Part 1, check the “Awaiting TIN” Box in Part 2, sign and date the form in the two spaces indicated, and return it to the payer. For interest and dividend payments and certain payments made with respect to readily tradable instruments, you will generally have 60 calendar days to get a TIN and give it to the payer. If the payer does not receive your TIN within 60 calendar days, backup withholding, if applicable, will begin and continue until you furnish your TIN.

Note: Writing “Applied For” on the form means that you have already applied for a TIN or that you intend to apply for one soon. As soon as you receive your TIN, complete another Form W-9, include your TIN, sign and date the form, and return it to the payer.

Payees Exempt from Backup Withholding

Generally, individuals (including sole proprietors) are not exempt from backup withholding. Corporations generally are exempt from backup withholding.

Note: If you are exempt from backup withholding, you should still complete Substitute Form W-9 to avoid possible

erroneous backup withholding. If you are exempt, enter your correct TIN in Part 1, check the “Exempt” Box in Part 2, and sign and date the form.

Exempt Payees

Backup withholding is not required on any payments made to the following payees:

(1) An organization exempt from tax under section 501(a), any IRA, or a custodial account under section 403(b)(7) if the account satisfies the requirements of section 401(f)(2).

(2) The United States or any of its agencies or instrumentalities.

(3) A state, the District of Columbia, a possession of the United States, or any of their political subdivisions or instrumentalities.

(4) A foreign government or any of its political subdivisions, agencies, or instrumentalities.

(5) An international organization or any of its agencies or instrumentalities.

Other payees that may be exempt from backup withholding include:

(6) A corporation.

(8) A dealer in securities or commodities required to register in the United States, the District of Columbia, or a possession of the United States.

FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, CHECK THE “EXEMPT” BOX IN PART 2 OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER.

Privacy Act Notice. Section 6109 of the Internal Revenue Code requires you to provide your correct TIN to persons who must file information returns with the IRS to report interest, dividends, and certain other income paid to you, mortgage interest you paid, the acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA, or Archer MSA or HSA. The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. The IRS may also provide this information to the Department of Justice for civil and criminal litigation, and to cities, states, the District of Columbia, and U.S. possessions to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism.

You must provide your TIN whether or not you are required to file a tax return. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to a payer. Certain penalties may also apply.

Penalties

Failure to Furnish TIN. If you fail to furnish your correct TIN to a payer, you are subject to a penalty of US$50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

Civil Penalty for False Information With Respect to Withholding. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a US$500 penalty.

Criminal Penalty for Falsifying Information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Misuse of TINs. If the payer discloses or uses TINs in violation of federal law, the payer may be subject to civil and criminal penalties.
