(c)                  Continued Compliance with Securities Laws . If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Representatives of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon the request of the Representatives, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d)                 Rule 158. As soon as practicable, but not later than 16 months, after the date of this Agreement, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the date of this Agreement and satisfying the provisions of Section 11(a) of the Act and Rule 158.

(h)                 Payment of Expenses . The Company will pay all expenses incident to the performance of its obligations under this Agreement, including but not limited to (i) any filing fees and other expenses incurred in connection with the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives designate and the preparation and printing of memoranda relating thereto; (ii) all expenses in connection with the execution, issue, authorization, authentication, packaging, transfer and initial delivery of the Offered Securities, the preparation and printing of this Agreement, the Offered Securities, the Indentures, the Registration Statement, the General Disclosure Package, the Final Prospectus, all amendments and supplements thereto, any Issuer Free Writing Prospectus and any other document related to the issuance, offer, sale and delivery of the Offered Securities; (iii) any fees charged by investment rating agencies for the rating of the Offered Securities; (iv) fees and expenses of the Trustee and its professional advisers, including legal counsel; (v) costs and expenses relating to any advertising, investor presentations or any “road show” in connection with the offering and sale of the Offered Securities including, without limitation, any travel expenses of the Underwriters’ and the Company’s officers and employees and any other related expenses of the Underwriters and the Company including the chartering of airplanes; (vi) fees and expenses incident to listing the Offered Securities on the Irish Stock Exchange; (vii) fees and expenses in connection with the registration of the Offered Securities under the Securities Act and the Exchange Act; (viii) expenses incurred in distributing preliminary prospectuses and the Final Prospectus (including any amendments and supplements thereto) and for expenses incurred for preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors, (ix) the fees and expenses of the Company’s counsel and the accountants incurred in distributing the General Disclosure Package, the Final Prospectus (including any amendments and supplements thereto) and any Issuer Free Writing Prospectus to the Underwriters; and (x) the reasonable fees and expenses of the Underwriters’ Peruvian, Mexican and U.S. counsel.

The Company will use the net proceeds received in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package.

(l)                   Listing. The Company will make or cause to be made an application for the Offered Securities to be listed on the Global Exchange Market of the Irish Stock Exchange Limited and will use commercially reasonable efforts to have the Offered Securities listed or admitted to trading on the Global Exchange Market of the Irish Stock Exchange Limited. The Company shall, from time to time, take such other actions as shall be necessary to maintain any listing of the Offered Securities in accordance with the terms hereof.

6. Free Writing Prospectuses . (a) Issuer Free Writing Prospectuses . The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “ Permitted Free Writing Prospectus .” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. The Company also consents to the use by any Underwriter of a free writing prospectus that contains only (i)(x) information describing the preliminary terms of the Offered Securities or their offering or (y) information that describes the final terms of the Offered Securities or their offering and that is included in the final term sheet of the Company contemplated in the first sentence of this subsection or (ii) other information that is not “issuer information,” as defined in Rule 433, it being understood that any such free writing prospectus referred to in clause (i) or (ii) above shall not be an Issuer Free Writing Prospectus for purposes of this Agreement.

7. Conditions of the Obligations of the Underwriters . The obligations of the several Underwriters to purchase and pay for the Offered Securities on the Closing Date will be subject to the accuracy of the representations and warranties of the Company herein (as though made on the Closing Date), to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

The Company shall have requested and caused Skadden, Arps, Slate, Meagher & Flom LLP, U.S. counsel for the Company, to have furnished to the Representatives their opinion, dated the Closing Date and addressed to the Representatives, in the form set forth on Exhibit A-1, Exhibit A-2 and Exhibit A-3 hereto.

The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder.

8. Indemnification and Contribution . (a) Indemnification of Underwriters . The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “ Indemnified Party ”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of Company . Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “ Underwriter Indemnified Party ”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of (a) the third paragraph of text under the caption “Underwriting” in the Final Prospectus, concerning the terms of the offering by the Underwriters; (b) the second sentence of the fourth paragraph of text under the caption “Underwriting” in the Final Prospectus, concerning market making by the Underwriters; and (c) the fifth, sixth, seventh and eighth paragraphs of text under the caption “Underwriting” in the Final Prospectus, concerning short sales, stabilizing transactions and purchases to cover positions created by short sales by the Underwriters.

(c) Actions against Parties; Notification . Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) Contribution . If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(d).

9. Default of Underwriters . If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on the Closing Date and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities that the Underwriters are obligated to purchase on the Closing Date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on the Closing Date. If any Underwriter or Underwriters so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities that the Underwriters are obligated to purchase on the Closing Date and arrangements satisfactory to the Representatives and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section.

The Company’s financial statements, financial statement schedules and our report thereon and our report on the effectiveness of the Company's internal control over financial reporting (which report expresses an adverse opinion on the effectiveness of the Company’s internal control over financial reporting because of a material weakness) are included in the Company’s annual report on Form 10-K for the year ended December 31, 2014 which is incorporated by reference in the preliminary prospectus supplement dated April 20, 2015 (the “Preliminary Prospectus”) and the final prospectus supplement dated April 20, 2015 (the “Final Prospectus” and together with the Preliminary Prospectus, the “Prospectus”), for the offer and sale of U.S.$500,000,000, 3.875% Notes due 2025 and U.S.$1,500,000,000, 5.875%% Notes due 2045 (collectively, the “Notes”) under registration statement (No. 333-203237) on Form S-3, filed by the Company under the Securities Act of 1933, as amended (the “Act”).

Read the unaudited consolidated financial statements of the Company and subsidiaries for January, February and March of both 2015 and 2014 furnished to us by the Company, officials of the Company having advised us that no such financial statements as of any date or for any period subsequent to March 31, 2015 were available.

2. Inquired of certain officials of the Company who have responsibility for financial and accounting matters whether the unaudited consolidated financial statements referred to in a(i) are stated on a basis substantially consistent with that of the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2014 which is incorporated by reference in the Prospectus.

The foregoing procedures do not constitute an audit conducted in accordance with the standards of the PCAOB. Also, they would not necessarily reveal matters of significance with respect to the comments in the following paragraph. Accordingly, we make no representations about the sufficiency of the foregoing procedures for your purposes.

As of March 31, 2015, common stock changed, debt (including short-term debt and the current portion of long-term debt) increased and consolidated net current assets and stockholders’ equity decreased as shown in the following table:

For the period from January 1, 2015 to March 31, 2015, consolidated net sales, operating income, net income and net income per share decreased, as compared to the same period in the previous year, as shown in the following table:

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinions set forth below.

In our examination, we have assumed the genuineness of all signatures including endorsements, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. As to any facts relevant to the opinions stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials, including the facts and conclusions set forth in the Officer’s Certificate.

We do not express any opinion with respect to the laws of any jurisdiction other than (i) the laws of the State of New York, (ii) the federal laws of the United States of America and (iii) the General Corporation Law of the State of Delaware (the “DGCL”).

The Underwriting Agreement, the Note Certificates and the Indentures are referred to herein collectively as the “Transaction Agreements.” “Organizational Documents” means those documents listed in paragraphs (n) through (q) above, “Scheduled Contracts” means those agreements or instruments described on Schedule II hereto, “Scheduled Orders” means those orders or decrees described on Schedule I to the Officer’s Certificate and “General Disclosure Package” means the Preliminary Prospectus Supplement, as amended and supplemented by the documents identified on Schedule B to the Underwriting Agreement.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that:

1. Based solely on our review of the Delaware Certificates, each of the Company and Southern Peru Limited is duly incorporated and is validly existing and in good standing under the DGCL.

2. The Company has the corporate power and authority to execute and deliver each of the Transaction Agreements and to consummate the issuance and sale of the Securities contemplated thereby.

3. The Underwriting Agreement and each Indenture has been duly authorized, executed and delivered by all requisite corporate action on the part of the Company under the DGCL and duly executed and delivered by the Company under the laws of the State of New York to the extent that such execution and delivery are governed by the laws of the State of New York.

4. Each of the Indentures constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms under the laws of the State of New York.

5. Neither the execution and delivery by the Company of the Transaction Agreements nor the consummation by the Company of the issuance and sale of the Securities contemplated thereby: (i) conflicts with the Organizational Documents; (ii) constitutes a violation of, or default under, any Scheduled Contract; (iii) contravenes any Scheduled Order; or (iv) violates the DGCL or any law, rule or regulation of the State of New York or the United States of America.

6. Neither the execution and delivery by the Company of the Transaction Agreements nor the consummation by the Company of the issuance and sale of the Securities contemplated thereby requires the consent, approval, licensing or authorization of, or any filing, recording or registration with, any court or governmental authority under any law, rule or regulation of the DGCL, the State of New York or the United States of America except for those consents, approvals, licenses and authorizations already obtained and those filings, recordings and registrations already made.

7. To our knowledge, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or to which any property of the Company or any of its subsidiaries is subject that are required to be disclosed in the General Disclosure Package and the Prospectus Supplement pursuant to Item 103 of Regulation S-K of the Rules and Regulations that are not so disclosed.

8. The Note Certificates have been duly authorized by all requisite corporate action on the part of the Company and duly executed by the Company under the DGCL, and when duly authenticated by the Trustee and issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Note Certificates will constitute valid and binding obligations of the Company, entitled to the benefits of the Indentures and enforceable against the Company in accordance with their terms under the laws of the State of New York.

9. The statements in the Prospectus Supplement and the General Disclosure Package under the captions “Description of the Notes” insofar as such statements purport to summarize certain provisions of the Indentures and the Note Certificates, fairly summarize such provisions in all material respects.

10. The Company is not and, solely after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the General Disclosure Package and the Prospectus Supplement , will not be an “investment company” as such term is defined in the Investment Company Act of 1940.

The opinions stated herein are subject to the following qualifications:

(a)                the opinions stated herein are limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws affecting creditors’ rights generally, and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

(b)                except to the extent expressly stated in the opinions contained herein, we do not express any opinion with respect to the effect on the opinions stated herein of (i) the compliance or non-compliance of any party to any of the Transaction Agreements with any laws, rules or regulations applicable to such party or (ii) the legal status or legal capacity of any party to any of the Transaction Agreements;

(c)                except to the extent expressly stated in the opinions contained herein, we do not express any opinion with respect to any law, rule or regulation that is applicable to any party to any of the Transaction Agreements or the transactions contemplated thereby solely because such law, rule or regulation is part of the regulatory regime applicable to any such party or any of its affiliates as a result of the specific assets or business operations of such party or such affiliates;

(d)                we do not express any opinion with respect to any securities, antifraud, derivatives or commodities laws, rules or regulations or Regulations T, U or X of the Board of Governors of the Federal Reserve System;

(e)                except to the extent expressly stated in the opinions contained herein, we have assumed that each of the Transaction Agreements constitutes the valid and binding obligation of each party to such Transaction Agreement, enforceable against such party in accordance with its terms;

(f)                we do not express any opinion with respect to whether the execution or delivery of any Transaction Agreement by the Company, or the performance by the Company of its obligations under any Transaction Agreement, will constitute a violation of, or a default under, any covenant, restriction or provision with respect to financial ratios or tests or any aspect of the financial condition or results of operations of the Company or any of its subsidiaries;

(g)                the opinion set forth in paragraph 7 above is based solely on our discussions with the officers of the Company responsible for the matters discussed therein, our review of documents furnished to us by the Company and our reliance on the representations and warranties of the Company contained in the Underwriting Agreement and the Officer’s Certificate; we have not made any other inquiries or investigations or any search of the public docket records of any court, governmental agency or body or administrative agency. In addition, we call to your attention that we have not been engaged by, nor have we rendered any advice to, the Company in connection with any legal or governmental proceedings. Accordingly, we do not have any special knowledge with respect to such matters. We understand that such matters have been and are being handled by other counsel;

(h)                we call to your attention that certain of the Scheduled Contracts are governed by laws other than those with respect to which we express our opinion, and we have not consulted attorneys admitted in any such jurisdiction; the opinions stated herein are based solely upon our understanding of the plain meaning of the language contained in such Scheduled Contracts, and we do not assume any responsibility for any interpretation thereof inconsistent with such understanding;

(i)                we do not express any opinion with respect to the enforceability of any provision contained in any Transaction Agreement relating to any indemnification, contribution, exculpation or waiver that may be contrary to public policy or violative of federal or state securities laws;

(j)                we call to your attention that irrespective of the agreement of the parties to any Transaction Agreement concerning personal jurisdiction over them, a court may decline to hear a case on grounds of forum non conveniens or other doctrine limiting the availability of such court as a forum for resolution of disputes; in addition, we call to your attention that we do not express any opinion with respect to the subject matter jurisdiction of the federal courts of the United States of America in any action arising out of or relating to any Transaction Agreement; and

(k)                to the extent that any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions contained in any Transaction Agreement, the opinions stated herein are subject to the qualification that such enforceability may be subject to, in each case, (i) the exceptions and limitations in New York General Obligations Law sections 5-1401 and 5-1402 and (ii) principles of comity or constitutionality.

In addition, in rendering the foregoing opinions we have assumed that:

(a)                 except to the extent expressly stated in the opinions contained herein with respect to the Company, neither the execution and delivery by the Company of the Transaction Agreements nor the consummation by the Company of the transactions contemplated thereby, including the issuance and sale of the Securities: (i) conflicts or will conflict with the Organizational Documents, (ii) constitutes or will constitute a violation of, or a default under, any lease, indenture, instrument or other agreement to which the Company or its property is subject, (iii) contravenes or will contravene any order or decree of any governmental authority to which the Company or its property is subject, (iv) violates or will violate any law, rule or regulation to which the Company or its property is subject or (v) requires the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under any law, rule or regulation of any jurisdiction.

This opinion is furnished only to you as representatives of the Underwriters and is solely for the Underwriters’ benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Underwriting Agreement. Without our prior written consent, this opinion may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any other person that acquires any Securities or that seeks to assert the rights of an Underwriter in respect of this opinion (other than an Underwriter’s successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

For purposes of our opinion, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed, electronic or photostatic copies, and the authenticity of the originals of such latter documents.

In addition, we have relied on factual statements and representations of the officers and other representatives of the Company and others, and we have assumed that such statements and representations are and will continue to be true, correct and complete without regard to any qualification as to knowledge or belief.

Our opinion is based on the U.S. Internal Revenue Code of 1986, as amended, U.S. Treasury regulations, judicial decisions, published positions of the U.S. Internal Revenue Service, and such other authorities as we have considered relevant, all as in effect as of the date of this opinion and all of which are subject to differing interpretations or change at any time (possibly on a retroactive basis). A change in the authorities upon which our opinion is based could affect the conclusions expressed herein. There can be no assurance, moreover, that the opinion expressed herein will be accepted by the U.S. Internal Revenue Service or, if challenged, by a court.

Based upon and subject to the foregoing, and subject to the limitations, qualifications, exceptions and assumptions set forth herein, in the Preliminary Prospectus Supplement or in the Prospectus Supplement we are of the opinion that, under current U.S. federal income tax law, although the discussion set forth in the Preliminary Prospectus Supplement and the Prospectus Supplement under the heading "United States Federal Income Tax Consequences to Non-U.S. Holders" does not purport to summarize all possible U.S. federal income tax considerations of the purchase, ownership and disposition of the Securities to Non-U.S. Holders (as defined therein), such discussion constitutes, in all material respects, a fair and accurate summary of the U.S. federal income tax considerations of the purchase, ownership and disposition of the Securities to Non-U.S. Holders who purchase the Securities pursuant to the Prospectus Supplement.

This opinion is furnished only to you as representatives of the Underwriters and is solely for the Underwriters' benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Underwriting Agreement. Except as set forth above, we express no opinion to any party as to any tax consequences, whether federal, state, local or foreign, of the offering of the Securities or of any transaction related thereto. Without our prior written consent, this opinion may not be relied upon by any other person for any purpose. This opinion is expressed as of the date hereof, and we are under no obligation to supplement or revise our opinion to reflect any legal developments or factual matters arising subsequent to the date hereof.

Very truly yours,

Ladies and Gentlemen:

We have acted as special counsel to Southern Copper Corporation, a Delaware corporation (the “Company”), in connection with the Underwriting Agreement, dated April [●], 2015 (the “Underwriting Agreement”), between you, as representatives of the several underwriters named therein (the “Underwriters”), and the Company, relating to the sale by the Company to the Underwriters of the Company’s $[●] aggregate principal amount of [●]% Notes due 2025 and $[●] aggregate principal amount of [●]% Notes due 2045 (collectively, the “Securities”) to be issued under the Indenture, dated as of April 16, 2010 (the “Base Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented by the Fifth Supplemental Indenture, dated as of April [●], 2015, between the Company and the Trustee, and the Sixth Supplemental Indenture, dated as of April [●], 2015, between the Company and the Trustee.

This letter is being furnished to you pursuant to Section 7(d) of the Underwriting Agreement.

In the above capacity, we have reviewed (i) the registration statement on Form S-3 (File No. 333-203237) of the Company relating to the Securities and other securities of the Company filed on April 3, 2015 with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”) allowing for delayed offerings pursuant to Rule 415 of the General Rules and Regulations under the Securities Act (the “Rules and Regulations”), including the Incorporated Documents (as defined below) and the information deemed to be a part of the registration statement pursuant to Rule 430B of the Rules and Regulations (such registration statement, being hereinafter referred to as the “Registration Statement”); (ii) the prospectus, dated April 3, 2015 (the “Base Prospectus”), which forms a part of and is included in the Registration Statement; (iii) the preliminary prospectus supplement, dated April 14, 2015 (together with the Base Prospectus and the Incorporated Documents, the “Preliminary Prospectus”), relating to the offering of the Securities in the form filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations and (iv) the prospectus supplement, dated April [●], 2015 (the “Prospectus Supplement” and, together with the Base Prospectus and the Incorporated Documents, the “Prospectus”), relating to the offering of the Securities in the form filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations. We also have reviewed the documents identified on Schedule A hereto filed with the Commission pursuant to the Securities Exchange Act of 1934, as amended, and incorporated by reference into the Registration Statement, Preliminary Prospectus and the Prospectus as of the date hereof (collectively, the “Incorporated Documents”), the “issuer free writing prospectus” (as defined in Rule 433(h)(1) of the Rules and Regulations) identified on Schedule B hereto relating to the Securities (the “Free Writing Prospectus”) and such other documents as we deemed appropriate.

Assuming the accuracy of the representations and warranties of the Company set forth in Sections 2(c)(i), 2(c)(iii) and 2(d) of the Underwriting Agreement, the Registration Statement became effective upon filing with the Commission pursuant to Rule 462 of the Rules and Regulations and, pursuant to Section 309 of the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), the Base Indenture has been qualified under the Trust Indenture Act, and to our knowledge, based solely upon our review of the Commission’s website, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

In addition, we have participated in conferences with officers and other representatives of the Company, representatives of the independent registered public accountants of the Company and you, as representatives of the several Underwriters, and Cleary Gottlieb Steen & Hamilton LLP, counsel for the several Underwriters, at which the contents of the Registration Statement, the Prospectus, the General Disclosure Package (as defined below) and related matters were discussed. We did not participate in the preparation of the Incorporated Documents but have, however, reviewed such documents and discussed the business and affairs of the Company with officers and other representatives of the Company. We do not pass upon, or assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference into the Registration Statement, the Prospectus or the General Disclosure Package and have made no independent check or verification thereof (except to the limited extent referred to in paragraph 9 of our opinion to you dated the date hereof and our opinion to you, dated the date hereof, relating to the discussion in the General Disclosure Package and the Prospectus Supplement under the heading “United States Federal Income Tax Consequences to Non-U.S. Holders”).

On the basis of the foregoing, (i) the Registration Statement, at the Effective Time (as defined below) and the Prospectus, as of the date of the Prospectus Supplement, appeared on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the Rules and Regulations (except that in each case we do not express any view as to the financial statements, schedules and other financial information included or incorporated by reference therein or excluded therefrom or the Statement of Eligibility on Form T-1 (the “Form T-1”)) and (ii) no facts have come to our attention that have caused us to believe that the Registration Statement, at the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as of the date of the Prospectus Supplement and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that in each case we do not express any view as to the financial statements, schedules and other financial information included or incorporated by reference therein or excluded therefrom, the report of management’s assessment of the effectiveness of internal controls over financial reporting or the auditors’ report on the effectiveness of the Company’s internal controls over financial reporting, or the statements contained in the exhibits to the Registration Statement, including the Form T-1).

In addition, on the basis of the foregoing, no facts have come to our attention that have caused us to believe that the General Disclosure Package, as of the Applicable Time (as defined below), contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that we do not express any view as to the financial statements, schedules and other financial information included or incorporated by reference therein or excluded therefrom, the report of management’s assessment of the effectiveness of internal controls over financial reporting or the auditors’ report on the effectiveness of the Company’s internal controls over financial reporting, or the statements contained in the exhibits to the Registration Statement, including the Form T-1).

As used herein, (i) “Effective Time” means the time of effectiveness of the Registration Statement for purposes of Section 11 of the Securities Act, as such section applies to the Underwriters, (ii) “Applicable Time” means [●]:00 [a./p.]m (Eastern time) on April [●], 2015 and (iii) “General Disclosure Package” means the Preliminary Prospectus, as amended and supplemented by the Free Writing Prospectus.

This letter is furnished only to you as representatives of the Underwriters and is solely for the Underwriters’ benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Underwriting Agreement. Without our prior written consent, this letter may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any other person that acquires any Securities or that seeks to assert the rights of an Underwriter in respect of this letter (other than an Underwriter’s successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

As Representatives of the Several Underwriters.

Ladies and Gentlemen:

We have acted as special Mexican counsel for Southern Copper Corporation, a corporation organized under the laws of the State of Delaware, United States of America (the " Company "), in connection with the offer and sale by the Company of U.S.$[●], [●]% Notes due 2025 (the " 2025 Notes ") and U.S.$[●] [●]% Notes due 2045 (the " 2045 Notes "), and together with the 2025 Notes, the " Offered Securities ”) pursuant to an Underwriting Agreement dated April [●], 2015 (the " Underwriting Agreement "), by and among the Company and you, as representatives of the several underwriters named in Schedule A thereto (collectively, the " Underwriters "). This opinion letter is furnished pursuant to Section 7(e) of the Underwriting Agreement.

Capitalized terms used herein and not otherwise defined, shall have the meaning ascribed to such terms in the Underwriting Agreement. All assumptions and statements of reliance herein have been made without any independent investigation or verification on our part, except to the extent otherwise expressly stated, and we express no opinion with respect to the subject matter or accuracy of such assumptions or items relied upon.

For the purposes of this opinion letter, we have examined copies of such documents, agreements and instruments, as we have deemed necessary or appropriate, including the following:

The documents referred to in items (a) through (f) above, are referred to herein collectively as the “ Transaction Documents ”.

In rendering the opinions expressed herein, we have assumed (i) the due authorization, execution and delivery of each of the Transaction Documents by each party thereto, and the power and authority of each such party, under all applicable laws and regulations to enter into, execute, deliver and perform their respective obligations under each of the Transaction Documents; (ii) that all approvals necessary for the validity and enforceability of each of the Transaction Documents (other than the Mexican governmental approvals, which are addressed below) have been obtained and are in full force and effect; (iii) the validity, binding effect and enforceability of each of the Transaction Documents under the laws governing them; (iv) the genuineness of all signatures and the authenticity of all opinions, documents and papers submitted to us; (v) that copies of all opinions, documents and papers submitted to us are complete and conform to the originals thereof; and (vi) that the offer and sale of the Offered Securities by the Company will not be made by way of a public offering in the United Mexican States (“ Mexico ”) and that no action has been or will be taken by the Company or the Underwriters, which should be deemed, under the applicable laws of Mexico, as an offering of securities to the public in Mexico.

As to questions of fact material to the opinions hereinafter expressed, we have, when relevant facts were not independently established by us, relied upon the representations and warranties of the Company and the Underwriters contained in the Underwriting Agreement, and certificates and oral or written statements and other information of or from public officials, officers and representatives of the Company and the Mexican Subsidiaries and such other persons as we have deemed necessary or appropriate for the opinions expressed below.

We are not representing the Company or any of the Mexican Subsidiaries in connection with any pending actions, investigations, suits or proceedings by or before any Mexican court or governmental agency, authority or body or any arbitrator, in which any of such persons are named defendants.

Based upon the foregoing and subject to the qualifications set forth below, we are of the opinion that:

(1)                Each of the Mexican Subsidiaries is a sociedad anónima de capital variable , duly organized and validly existing under the laws of Mexico, with general corporate power and authority to conduct its business as described in the Registration Statement, the General Disclosure Package and the Final Prospectus.

(2)                Based solely on our review of the Stock Registry Books, all the outstanding shares of capital stock of each of the Mexican Subsidiaries have been duly and validly authorized and issued and are fully paid and non-assessable, and except for minority participations owned by other non-related persons, the outstanding shares of the capital stock of the Mexican Subsidiaries are owned by Americas Sales Company Inc., either directly, or through majority owned subsidiaries, and are free and clear of any security interest, claim, lien or encumbrance.

(3)                No consent or authorization by, and no notice to, or filing or registration with, any Mexican court or governmental authority, is required for the execution and performance by the Company of the Underwriting Agreement, the Indentures or the Offered Securities.

(4)                The statements included in the Form 10-K as filed by the Company with the U.S. Securities and Exchange Commission for the year ended December 31, 2014, under the headings (including the information referenced or incorporated by reference therein) “Item 1. Business—Labor Force—Mexico”, “Item 1. Business—Fuel, Electricity and Water Supplies—Mexico”, “Item 1. Business—Environmental Matters”, “Item 1. Business—Mining Rights and Concessions—Mexico”, “Item 1A. Risk Factors—Operational risks—Our Company is subject to health and safety laws which may restrict our operations, result in operational delays or increase our operating costs and adversely affect our financial results of operations”, “Item 1A. Risk Factors—Operational risks—We may be adversely affected by labor disputes”, "Item 1A. Risk Factors—Operational risks—Environmental, regulatory response to climate change, and other regulations may increase our costs of doing business, restrict our operations or result in operational delays", "Item 1A. Risk Factors—Other risks—Applicable law restricts the payment of dividends from our Minera Mexico subsidiary to us”, "Item 1A. Risk Factors—Risks Associated with Doing Business in Peru and Mexico—There is uncertainty as to the termination and renewal of our mining concessions", "Item 1A. Risk Factors—Risks Associated with Doing Business in Peru and Mexico—Mexican economic and political conditions, as well as drug-related violence, may have an adverse impact on our business", "Item 1A. Risk Factors—Risks Associated with Doing Business in Peru and Mexico—Mexican inflation, restrictive exchange control policies and fluctuations in the peso exchange rate may adversely affect our financial condition and results of operations” and "Item 3. Legal Proceedings", insofar as such statements purport to summarize or relate to legal proceedings in Mexico or provisions of Mexican laws or regulations, are accurate and fair summaries of such laws or regulations in all material respects.

(5)                No stamp or other transfer taxes or duties and no capital gains, income, withholding or other similar taxes are payable in Mexico or any political subdivision thereof or to any authority having power to tax therein, in connection with the execution, delivery or performance of the Underwriting Agreement or the Indentures by the Company, or the sale or delivery of the Offered Securities by the Company to the Underwriters or the initial resales thereof by the Underwriters in the manner contemplated by the Underwriting Agreement, the General Disclosure Package and the Final Prospectus.

(6)                The Underwriters will not, under current Mexican law, be deemed to be residents of Mexico and subject to taxation in Mexico, by reason solely of the execution, performance or enforcement of the Underwriting Agreement.

(7)                Neither the execution and delivery of the Underwriting Agreement and the Indentures, nor the issuance and sale of the Offered Securities by the Company to the Underwriters or the initial resales of the Offered Securities by the Underwriters in the manner contemplated by the Underwriting Agreement, the General Disclosure Package and the Final Prospectus, nor the consummation of any other of the transactions therein contemplated, nor the fulfillment of the terms thereof will conflict with, result in a breach or violation of, or constitute a default under, or result in the imposition of any lien, charge or encumbrance upon any property or assets of the Mexican Subsidiaries pursuant to (i) the Organizational Documents of each of the Mexican Subsidiaries, or (ii) any Mexican federal statute, law, rule, or regulation, applicable to the Mexican Subsidiaries, of any federal Mexican regulatory body, administrative agency, governmental body, or other Mexican federal authority having jurisdiction over each of the Mexican Subsidiaries or any of their respective properties.

We express no opinion as to any laws other than the federal laws of Mexico in effect as of the date hereof. We assume no obligation to supplement this opinion letter if any applicable law changes after the date hereof or if we become aware of any facts that might change the opinions expressed herein after the date hereof. Except as specifically stated herein, we make no comment with regard to any representations made or which may be made by the Company or the Mexican Subsidiaries in any of the Transaction Documents or otherwise. The opinions contained herein are limited to the matters expressly stated herein, in each case as of the date hereof, and no opinion may be inferred or may be implied beyond such matters.

This opinion letter is furnished to you solely for your benefit in connection with the Transaction Documents. This opinion may not be used, circulated, transmitted, quoted or otherwise referred to for any other purpose, or relied upon by any other person without our prior written consent.

Very truly yours,

González Calvillo, S.C.

We have acted as special Mexican counsel for Southern Copper Corporation, a corporation organized under the laws of the State of Delaware, United States of America (the " Company "), in connection with the offer and sale by the Company of U.S.$[●], [●]% Notes due 2025 (the " 2025 Notes ") and U.S.$[●] [●]% Notes due 2045 (the " 2045 Notes "), and together with the 2025 Notes, the " Offered Securities ”) pursuant to an Underwriting Agreement dated April [●], 2015 (the "Underwriting Agreement "), by and among the Company and you as representatives of the several underwriters named in Schedule A thereto (collectively, the " Underwriters "). This letter is furnished pursuant to Section 7(e) of the Underwriting Agreement. Capitalized terms used herein and not otherwise defined, shall have the meaning ascribed to such terms in the Underwriting Agreement. All assumptions and statements of reliance herein have been made without any independent investigation or verification on our part, except to the extent otherwise expressly stated, and we express no opinion with respect to the subject matter or accuracy of such assumptions or items relied upon.

As special Mexican counsel to the Company in connection with the offer and sale of the Offered Securities, we have reviewed (i) the Registration Statement; (ii) the Final Prospectus, and (iii) the General Disclosure Package, and participated in discussions with representatives of the Company, its accountants, its United States and Peruvian counsel and with your representatives and your United States, Mexican and Peruvian counsel, in which the contents of the Registration Statement, the General Disclosure Package and the Final Prospectus and related matters were discussed. In addition, we reviewed and have relied upon certificates of certain officers of the Company and/or the subsidiaries of the Company listed in Exhibit “A” hereto (the “ Mexican Subsidiaries ”).

Because the primary purpose of our professional engagement was not to establish or confirm factual matters or financial or accounting matters, and because many determinations involved in the preparation of the Registration Statement, the General Disclosure Package and the Final Prospectus are of a wholly or partially non-legal character or relate to legal matters outside the scope of this letter, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package and the Final Prospectus (except to the extent expressly set forth in numbered paragraph 4 of the opinion letter furnished to you of even date herewith and subject to the terms of such opinion), and we make no representation that we have independently verified the accuracy, completeness or fairness of such statements. Without limiting the foregoing, we assume no responsibility for, and have not independently verified the accuracy, completeness or fairness of the financial statements and schedules and other financial, technical, operating and industry-related data (including, without limitation, information regarding the Company’s and the Mexican Subsidiaries’ mining reserves), included in the Registration Statement, the General Disclosure Package and the Final Prospectus, and we have not examined the accounting and financial records from which such financial statements, schedules and data are derived.

However, based upon our review of the Registration Statement, the General Disclosure Package and the Final Prospectus, considered in the light of our understanding of the applicable Mexican federal laws and policy and the experience we have gained through our practice in Mexico thereunder, and our participation in the aforementioned discussions; we advise you, solely with respect to the Mexican Subsidiaries, that nothing has come to our attention that causes us to believe that: (i) the Registration Statement or any amendment thereto as of the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) the Final Prospectus or any amendment thereto, as of the date thereof and as of the date of this letter, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (iii) the General Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. We make no statement as to the financial statements and notes thereto and financial schedules and other financial, technical, operating and industry-related data included in the Registration Statement, the Final Prospectus and the General Disclosure Package or omitted therefrom.

We are attorneys authorized to practice laws in Mexico. We therefore express no opinion as to any laws other than the federal laws of Mexico in effect as of the date hereof. In particular, we express no view with respect to, under, or in connection with, the United States securities laws and regulations, or the interpretation thereof or practice thereunder.

We assume no obligation to supplement this letter after the date hereof. The views contained herein are limited to the matters expressly stated herein, in each case as of the date hereof, and no view or statement may be inferred or may be implied beyond such matter.

This letter is delivered to you solely for your benefit in connection with the offering by the Company of the Offered Securities. This letter may not be used, circulated, transmitted, quoted or otherwise referred to for any other purpose, or relied upon by any other person without our prior written consent.

Very truly yours,

González Calvillo, S.C.

as Representatives of the several Underwriters

Ladies and gentlemen:

We have acted as special Peruvian counsel to Southern Copper Corporation, a corporation organized under the laws of the State of Delaware, United States of America (the “Company”), in connection with the offer and sale by the Company of US$[___] [___]% Notes due 2025 (the “2025 Notes”) and US$[___] [___]% Notes due 2045 (the “2045 Notes” and, together with the 2025 Notes, the “Offered Securities”), pursuant to an Underwriting Agreement dated April [___], 2015, entered into by and among the Company and you, as Representatives of the several Underwriters (the “Underwriting Agreement”). This opinion letter is furnished pursuant to Section 7(f) of the Underwriting Agreement. Capitalized terms used and not otherwise defined herein shall have the meaning ascribed to such terms in the Underwriting Agreement.

In rendering the opinions expressed below we have examined an executed copy (or a copy certified to our satisfaction) of the following documents (the “Transaction Documents”):

In addition, we have examined the following documents:

In such examination we have assumed without any independent investigation or verification of any kind (i) the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to the original documents of all documents submitted to us as certified, photostatic, electronic or facsimile copies, (ii) the due authorization, execution and delivery of the Underwriting Agreement, the Indentures and the Offered Securities by each of the parties thereto, (iii) that the performance of the Underwriting Agreement, the Indentures and the Offered Securities is within the capacity and powers of each of the parties thereto, and (iv) the legality, validity, binding nature and enforceability of the Underwriting Agreement, the Indentures and the Offered Securities under the laws of the State of New York, United States of America. Also, we have relied on and assume the accuracy of the documents we have examined, including without limitation the representations and warranties as to matters of fact and the covenants contained in the Underwriting Agreement, the Indentures and the Offered Securities and the certificates or other documents delivered in connection therewith or herewith.

We have further assumed that the execution, delivery and performance by the parties to the Underwriting Agreement, the Indentures and the Offered Securities (i) do not require any notice to, or filing or registration by, the Company or any of the other parties to the Underwriting Agreement, the Indentures or the Offered Securities with, or the grant of any approval or consent to the Company or any of the other parties to the Underwriting Agreement, the Indentures or the Offered Securities of, any court or governmental agency, authority or body that has not been made or obtained other than any court or governmental agency, authority or body in the Republic of Peru, and (ii) do not violate or conflict with any law or regulation of any governmental agency, authority or body of any jurisdiction other than those in force and effect in the Republic of Peru.

We express no opinion as to any laws other than the laws of the Republic of Peru and we have assumed that there is nothing in any other law or jurisdiction that affects our opinion. In particular we have made no independent investigation of the laws of the United States of America or any jurisdiction thereof as a basis for the opinions expressed below and do not express or imply any opinion on or based on the criteria or standards provided for in such laws.

As to questions of fact material to the opinions expressed below, we have not undertaken an independent verification and have solely relied upon originals or copies, certified or otherwise identified to our satisfaction, of all such corporate records of SPCC Peru Branch and such other instruments or certificates of public officials, officers and representatives of the Company and SPCC Peru Branch and such other persons as we have deemed necessary or appropriate for the opinions expressed below.

We express no view as to any transaction, fact or situation in which the Company or SPCC Peru Branch has been involved outside of the Republic of Peru, except to the extent that any such transaction, fact or situation implicates Peruvian applicable law, in which case we have reviewed such transaction, fact or situation only with respect to the implications thereof under Peruvian applicable law.

We assume no responsibility for, and have not independently verified, the accuracy, completeness or fairness of the financial statements and schedules and other financial and accounting data included in the Transaction Documents, and we have not examined the accounting and financial records from which such financial statements, schedules and data are derived.

Based upon the foregoing and subject to the qualifications set forth below, we are of the opinion that:

We are not aware of any reason why the enforcement in the Republic of Peru of such a judgment in respect of the Underwriting Agreement, the Indentures or the Offered Securities would be contrary to public order or good morals of the Republic of Peru.

The opinions expressed above are subject to the following qualifications:

This opinion letter shall in no way be construed as stating any view, express or implied, based upon the securities laws (federal or state) of the United States of America, the interpretation thereof or the practice thereunder, with respect to which we have no knowledge or understanding. The language included above is included herein as a matter of convention only but shall not be interpreted or construed as stating any view under any securities laws or any other legal provision (federal or state) of the United States of America.

The opinions expressed above are given as of the date hereof and we undertake no obligation to supplement this opinion letter if any applicable law changes after the date hereof or if we become aware of any facts that might change the opinions expressed above after the date hereof or for any other reason.

This opinion letter is provided to each of you by us in our capacity as special Peruvian counsel to the Company and may not be relied upon by any other person for any purpose other than in connection with the transactions contemplated by the Underwriting Agreement without, in each instance, our prior written consent.

Very truly yours,

as Representatives of the several Underwriters

Ladies and gentlemen:

We have been engaged as special Peruvian counsel to Southern Copper Corporation, a corporation organized under the laws of the State of Delaware, United States of America (the “Company”), in connection with the offer and sale by the Company of US$[___] [___]% Notes due 2025 (the “2025 Notes”) and US$[___] [___]% Notes due 2045 (the “2045 Notes” and, together with the 2025 Notes, the “Offered Securities”), pursuant to an Underwriting Agreement dated April [___], 2015, entered into by and among the Company and you, as Representatives of the several Underwriters (the “Underwriting Agreement”). This letter is furnished pursuant to Section 7(f) of the Underwriting Agreement. Capitalized terms used and not otherwise defined herein shall have the meaning ascribed to such terms in the Underwriting Agreement.

As special Peruvian counsel to the Company we have examined such documents and records as we have deemed appropriate, including copies of (i) the registration statement on Form S-3 (File No. 333-203237) relating to the Offered Securities and other securities of the Company filed by the Company with the U.S. Securities and Exchange Commission on April 3, 2015 (the “Registration Statement”), (ii) the prospectus, dated April 3, 2015, which forms a part of and is included in the Registration Statement (the “Base Prospectus”), (iii) the preliminary prospectus supplement, dated April [___], 2015 (together with the Base Prospectus, the “Preliminary Prospectus”), relating to the Offered Securities, and (iv) the prospectus supplement, dated April [___], 2015, relating to the Offered Securities (the “Prospectus Supplement” and, together with the Base Prospectus, the “Prospectus”). We also have examined the documents identified on Schedule I hereto relating to the Offered Securities (the documents in Schedule I hereto and the Preliminary Prospectus are collectively hereinafter referred as the “General Disclosure Package”), and such other documents as we deemed appropriate. As special Peruvian legal counsel to the Company we have participated in conference calls with your representatives and representatives of the Company, your international, Mexican and Peruvian counsel, the Company’s international and Mexican counsel and the Company’s independent public accountants at which the contents of the Registration Statement, the Prospectus and the General Disclosure Package and related matters were discussed.

The purpose of our professional engagement was to render legal services on Peruvian legal matters in connection with, among other things, the Registration Statement, the Prospectus and the General Disclosure Package and not to establish or confirm factual, financial, accounting, operating or statistical matters set forth in the Registration Statement, the Prospectus or the General Disclosure Package and we have not undertaken any obligation to verify any such matters set forth in the Registration Statement, the Prospectus or the General Disclosure Package. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Prospectus and the General Disclosure Package are not related to Peruvian legal matters.

Subject to the foregoing and to the following paragraphs, we confirm to each of you that, in the course of performing the services referred to above, nothing came to our attention that caused us to believe that (i) the Registration Statement (including the documents incorporated by reference therein) or any amendment thereto, as of the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein not misleading, (ii) the Prospectus (including the documents incorporated by reference therein) or any amendment thereto, as of the date thereof and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) the General Disclosure Package (including the documents incorporated by reference therein), as of the Applicable Time, contained an untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Prospectus or the General Disclosure Package (except to the extent expressly set forth in numbered paragraph 5 of our opinion letter to you of even date herewith) and we do not express any belief with respect to the financial statements or other financial or accounting data or the operating data contained in or omitted from the Registration Statement, the Prospectus or the General Disclosure Package.

We are attorneys authorized to practice law in the Republic of Peru. We therefore express no view with respect to any laws other than the laws of the Republic of Peru as currently in effect. In particular we express no view with respect to, under, or in connection with, the securities laws (federal or state) of the United States of America, the interpretation thereof or the practice thereunder, with respect to which we have no knowledge or understanding.

The views contained herein are limited to the matters expressly stated in this letter and no view or statement may be inferred or may be implied beyond such matters. We undertake no obligation to supplement this letter after the date hereof.

This letter is being furnished only to each of you at the request of our client the Company, is solely for your benefit in your capacity as Representatives of the several Underwriters and is not to be used, quoted, relied upon or otherwise referred to by any other person (including any person purchasing any of the Offered Securities (or beneficial interests therein) from you or any of your affiliates or any other investor therein) or for any other purpose other than in connection with the transactions contemplated by the Underwriting Agreement without, in each instance, our prior written consent.

Very truly yours,

Schedule I

General Use Free Writing Prospectus containing the final terms sheet relating to the offering of the Offered Securities, dated April [___], 2015, filed by the Company with the U.S. Securities and Exchange Commission on April [___], 2015.
