On June 24, 2026, Southern Copper Corporation (the "Company") completed a registered public offering (the "Offering") of U.S.$1.25 billion aggregate principal amount of its 5.350% notes due 2036 (the "Notes"). The Notes will bear interest from June 24, 2026, payable semi-annually on June 24 and December 24 of each year, beginning on December 24, 2026. The Notes were offered by the Company pursuant to its Registration Statement on Form S-3 (File No.333-296778) and the Prospectus included therein, filed with the Securities and Exchange Commission on June 15, 2026 and supplemented by the Prospectus Supplement dated June 16, 2026. The Offering resulted in net proceeds, after deducting estimated offering expenses and underwriters' discounts of approximately U.S.$2,500,000, of approximately U.S.$1,241,262,500. The net proceeds from this Offering will be used by Southern Peru Copper Corporation, Sucursal del Perú, our Peruvian branch ("SPCC"), for the development of the Tia Maria project, the financing of the capital expenditure program of SPCC, and/or for general corporate purposes of SPCC, including but not limited to working capital (and expenses due in the short term).

On June 16, 2026, the Company entered into an Underwriting Agreement, dated June 16, 2026 (the "Underwriting Agreement"), with BofA Securities, Inc., Morgan Stanley & Co. LLC, Barclays Capital Inc. and Santander US Capital Markets LLC (collectively, the "Underwriters"), in connection with the issuance and sale by the Company of the Notes. Pursuant to the Underwriting Agreement, the Company agreed to sell the Notes to the Underwriters, and the Underwriters agreed to purchase the Notes for resale to the public. The Underwriting Agreement includes customary representations, warranties and covenants by the Company. It also provides for customary indemnification by each of the Company and the Underwriters against certain liabilities and customary contribution provisions in respect of those liabilities.

Pursuant to an Indenture, dated April 16, 2010 (the "Indenture"), between the Company and Computershare Trust Company, National Association, as trustee (the "Trustee"), the Company and the Trustee entered into a Seventh Supplemental Indenture dated as of June 24, 2026 (the "Seventh Supplemental Indenture"). The Seventh Supplemental Indenture provides for the issuance, and set forth the terms of, the Notes. The Indenture and the Seventh Supplemental Indenture contain covenants that limit the Company's ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company's assets. The Company may issue additional debt from time to time pursuant to the Indenture.

The foregoing description of the Underwriting Agreement, the Seventh Supplemental Indenture is qualified in its entirety by reference to the full text of such documents, which are filed as Exhibits 1 and 4.1 hereto, respectively, and incorporated herein by reference.

(i)(A) At the time the Registration Statement initially became effective, (B) at the time of each amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether by post effective amendment, incorporated report or form of prospectus), (C) at the Effective Time relating to the Offered Securities and (D) on the Closing Date, the Registration Statement conformed and will conform in all respects to the requirements of the Act, the Trust Indenture Act and the Rules and Regulations and did not and will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (ii)(A) on its date, (B) at the time of filing the Final Prospectus pursuant to Rule 424(b) and (C) on the Closing Date, the Final Prospectus will conform in all material respects to the requirements of the Act, the Trust Indenture Act and the Rules and Regulations, and will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from any such document based upon 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 is that described as such in Section 8(b) hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp; *Automatic Shelf Registration Statement*. (i) Well-Known Seasoned Issuer Status. (A) At the time of initial filing of the Registration Statement, (B) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), and (C) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Offered Securities in reliance on the exemption of Rule 163, the Company was a "**well known seasoned issuer**" as defined in Rule 405, including not having been an "**ineligible issuer**" as defined in Rule 405.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp; *Effectiveness of Automatic Shelf Registration Statement*. The Registration Statement is an "automatic shelf registration statement," as defined in Rule 405, that initially became effective within three years of the date of this Agreement. If immediately prior to the Renewal Deadline (as hereinafter defined), any of the Offered Securities remain unsold by the Underwriters, the Company will prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Offered Securities, in a form reasonably satisfactory to the Representatives. If the Company is no longer eligible to file an automatic shelf registration statement, the Company will prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Offered Securities, in a form reasonably satisfactory to the Representatives, and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action reasonably necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the expired registration statement relating to the Offered Securities. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be. "**Renewal Deadline**" means the third anniversary of the initial effective time of the Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp; *Eligibility to Use Automatic Shelf Registration Form*. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to use of the automatic shelf registration statement form. If at any time when Offered Securities remain unsold by the Underwriters the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Offered Securities, in a form reasonably satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable, and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)&nbsp;&nbsp;&nbsp;&nbsp; *Filing Fees*. The Company has paid or shall pay the required Commission filing fees relating to the Offered Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp; *Ineligible Issuer Status*. (i) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Offered Securities and (ii) at the date of this Agreement, the Company was not and is not an "ineligible issuer," as defined in Rule 405, including (x) the Company or any other subsidiary in the preceding three years not having been convicted of a felony or misdemeanor or having been made the subject of a judicial or administrative decree or order as described in Rule 405 and (y) the Company in the preceding three years not having been the subject of a bankruptcy petition or insolvency or similar proceeding, not having had a registration statement be the subject of a proceeding under Section 8 of the Act and not being the subject of a proceeding under Section 8A of the Act in connection with the offering of the Securities, all as described in Rule 405.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *General Disclosure Package*. As of the Applicable Time, neither (i) the General Use Issuer Free Writing Prospectus(es) issued at or prior to the Applicable Time, the preliminary prospectus supplement, dated June 15, 2026, including the base prospectus, dated June 15, 2026, (which is the most recent Statutory Prospectus distributed to investors generally), and the other information, if any, stated in Schedule B to this Agreement to be included in the General Disclosure Package, all considered together (collectively, the "**General Disclosure Package**"), nor (ii) any individual Limited Use Issuer Free Writing Prospectus specified in Schedule B, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to (i) that part of the Registration Statement which shall constitute the Trustee's Statement of Eligibility and Qualifications (Form T-1) under the Trust Indenture Act, or (ii) any statements in or omissions from any Statutory Prospectus or any Issuer Free Writing Prospectus 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 Section 8(b) hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Incorporated Documents*. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Final Prospectus or the General Disclosure Package at the time they were or hereafter are filed with the Commission, complied or will comply in all material respects as to form with the requirements of the Exchange Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)&nbsp;&nbsp;&nbsp;&nbsp; *Issuer Free Writing Prospectuses*. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Offered Securities or until any earlier date that the Company notified or notifies the Representatives as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or as a result of which such Issuer Free Writing Prospectus, if republished immediately following such event or development, would include an untrue statement of a material fact or omitted or would omit 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, (i) the Company has promptly notified or will promptly notify the Representatives and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Purchase, Sale and Delivery of Offered Securities*. On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Company agrees to sell to the several Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, as set forth opposite the names of the Underwriters in Schedule A hereto, the principal amounts of Offered Securities, at a purchase price of 99.501% of the principal amount, plus accrued interest from June 24, 2026 to the Closing Date (as hereinafter defined).

The Company will deliver the Offered Securities to or as instructed by the Representatives for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment of the purchase price by the Underwriters in Federal (same day) funds by wire transfer to an account at a bank acceptable to the Underwriters at the office of Davis Polk & Wardwell LLP, at 10:00 a.m., New York time, on June 24, 2026, or at such other time not later than three full business days thereafter as the Representatives and the Company determine, such time being herein referred to as the "**Closing Date**". For purposes of Rule 15c6-1 under the Exchange Act, the Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. The Offered Securities so to be delivered or evidence of their issuance will be made available for checking at the above office at least 24 hours prior to the Closing Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.&nbsp;&nbsp;&nbsp;&nbsp; *Offering by Underwriters*. It is understood that the several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Final Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Certain Agreements of the Company*. The Company agrees with the several Underwriters that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Filing of Prospectuses*. The Company has filed or will file each Statutory Prospectus (including the Final Prospectus) pursuant to and in accordance with Rule 424(b)(2) (or, if applicable and consented to by the Representatives, subparagraph (5)) not later than the second business day following the earlier of the date it is first used or the execution and delivery of this Agreement. The Company has complied and will comply with Rule 433.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp; *Filing of Amendments; Response to Commission Requests*. The Company will promptly advise the Representatives of any proposal to amend or supplement the Registration Statement or any Statutory Prospectus at any time and will offer the Representatives a reasonable opportunity to comment on any such amendment or supplement; and the Company will also advise the Representatives promptly of (i) the filing of any such amendment or supplement, (ii) any request by the Commission or its staff for any amendment to the Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iii) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or the threatening of any proceeding for that purpose, and (iv) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp; *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.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp; *Rule 158*.

The Company will arrange for the qualification of the Offered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Reporting Requirements*.

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. The Company will not use any of the proceeds from the sale of the Offered Securities in such a way that would require the participation of a "qualified independent underwriter" within the meaning of FINRA Rule 2720.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)&nbsp;&nbsp;&nbsp;&nbsp; *Absence of Manipulation*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Term Sheets*.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *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 Final Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 5(a) hereof. No stop order suspending the effectiveness of the Registration Statement or of any part thereof shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or any Underwriter, shall be contemplated by the Commission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *No Material Adverse Change*. Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, properties or prospects of the Company and its subsidiaries taken as a whole which, in the judgment of the Representatives, is material and adverse and makes it impractical or inadvisable to market the Offered Securities; (ii) any downgrading in the rating of any debt securities of the Company by any "nationally recognized statistical rating organization" (as defined in Section 3(a)(62) of the Exchange Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating); (iii) any change in U.S., Mexican, Peruvian or international financial, political or economic conditions or currency exchange rates or exchange controls the effect of which is such as to make it, in the reasonable judgment of the Representatives, impractical to market or to enforce contracts for the sale of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any suspension or material limitation of trading in securities generally on the New York Stock Exchange or the Lima Stock Exchange, or any setting of minimum or maximum prices for trading on such exchange; (v) or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (vi) any banking moratorium declared by any U.S. federal or New York authorities; (vii) any major disruption of settlements of securities, payment, or clearance services in the United States or any other country where such securities are listed or (viii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, Mexico or Peru, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Representatives, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency is such as to make it impractical or inadvisable to market the Offered Securities or to enforce contracts for the sale of the Offered Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Opinion of U.S. Counsel for the Company*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.&nbsp;&nbsp;&nbsp;&nbsp; *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 and documented 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.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *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. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs, and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp; *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 and documented 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 underwriting commissions received by such Underwriter in connection with the Offered Securities underwritten by it and distributed 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).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *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. Nothing herein will relieve a defaulting Underwriter from liability for its default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.&nbsp;&nbsp;&nbsp;&nbsp; *Survival of Certain Representations and Obligations*. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 hereof, the Company will reimburse the Underwriters for all reasonable and documented out-of-pocket expenses (including fees and disbursements of counsel) incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Notices*. All communications hereunder will be in writing and will be mailed, delivered or telegraphed and confirmed, to the addresses below:

Exhibit A-1<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; a copy of a certificate, dated [●], 2026, and bringdown verification thereof, dated the date hereof, in each case from the Secretary of State of the State of Delaware or a registered agent thereof with respect to the Company's existence and good standing in the State of Delaware (collectively, the "Delaware Certificate"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; copies of each of the Scheduled Contracts (as defined below).

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 stated below.

In our examination, we have assumed the genuineness of all signatures, including electronic signatures, 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 photocopied 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 and the Secretary's Certificate and the factual representations and warranties contained in the Transaction Documents.

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 Indenture are referred to herein collectively as the "Transaction Documents." As used herein, (a) "Organizational Documents" means the Certificate of Incorporation and the Bylaws; (b) "Scheduled Contracts" means those agreements or instruments described on Schedule I hereto; (c) "Scheduled Orders" means those orders or decrees described on Schedule II hereo and (d) "Disclosure Package" means the Preliminary Prospectus, as amended and supplemented by the Pricing Term Sheet.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;&nbsp;&nbsp; Based solely on our review of the Delaware Certificate, the Company is duly incorporated and is validly existing and in good standing under the DGCL.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;&nbsp;&nbsp;&nbsp; The Company has the corporate power and authority to execute and deliver each of the Transaction Documents and to consummate the issuance and sale of the Securities contemplated thereby under the DGCL.

Ladies and Gentlemen:

We have acted as special United States counsel to Southern Copper Corporation, a Delaware corporation (the "<u>Company</u>" or "<u>Our Client</u>"), in connection with the Underwriting Agreement, dated [●], 2026 (the "<u>Underwriting Agreement</u>"), between you, as representatives of the several underwriters named therein (the "<u>Underwriters</u>"), and the Company, relating to the sale by the Company to the Underwriters of the Company's $[●] aggregate principal amount of [●]% Notes due 20[●](the "<u>Notes</u>") to be issued under the Indenture, dated as of April 16, 2010 (the "<u>Base Indenture</u>"), between the Company and Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association), as trustee (the "<u>Trustee</u>"), as supplemented by the Seventh Supplemental Indenture, dated as of [●], 2026 (the "<u>Seventh Supplemental Indenture</u>"), between the Company and the Trustee, between the Company and the Trustee (each an "<u>Indenture</u>" and together the "<u>Indentures</u>").

This opinion is being furnished to you pursuant to Section 7(d) of the Underwriting Agreement. The delivery of this opinion is not intended to create, nor shall it create, an attorney-client relationship with you or any other party except Our Client.

In rendering the opinion stated herein, we have examined and relied upon the following:

Exhibit A-2<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the registration statement on Form S-3 (File No. 333-[●]) of the Company, relating to the Securities and other securities of the Company filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "<u>Securities Act</u>") on [●], 2026 allowing for delayed offerings pursuant to Rule 415 of the General Rules and Regulations under the Securities Act (the "<u>Rules and Regulations</u>"), including information deemed to be a part of the registration statement pursuant to Rule 430B of the Rules and Regulations (such registration statement, including the Incorporated Documents (as defined below), being hereinafter referred to as the "<u>Registration Statement</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the prospectus, dated [●], 2026 (the "<u>Base Prospectus</u>"), which forms a part of and is included in the Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp; the preliminary prospectus supplement, dated [●], 2026 (together with the Base Prospectus and the Incorporated Documents, the "<u>Preliminary Prospectus Supplement</u>"), relating to the offering of the Securities, in the form filed by the Company pursuant to Rule 424(b) of the Rules and Regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp; the final prospectus supplement, dated [●], 2026 (together with the Base Prospectus and the Incorporated Documents, the "<u>Prospectus Supplement</u>"), relating to the offering of the Securities, in the form filed by the Company on [●], 2026, pursuant to Rule 424(b) of the Rules and Regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the Underwriting Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the Indentures.

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, 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 opinion stated below.

In our examination, 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 facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. For purposes of this opinion, we have assumed that such documents are duly authorized, valid, and enforceable and that the parties to such documents will comply with the terms thereof. Where documents have been provided to us in draft form, we have assumed that the final executed versions of such documents will not differ materially from such drafts. As to any facts material to the opinion expressed 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 have assumed that such statements are complete and accurate without regard to any qualification as to knowledge or belief.

Our opinion is based on the Internal Revenue Code of 1986, as amended, Treasury regulations promulgated thereunder, judicial decisions, published positions of the Internal Revenue Service (the "<u>Service</u>"), and such other authorities as we have considered relevant, all as in effect on the date of this opinion and all of which are subject to change or differing interpretations (possibly with retroactive effect). A change in the authorities or in the truth, accuracy, or completeness of any of the information, documents, certificates, records, statements, representations, or assumptions upon which our opinion is based could affect the conclusions expressed herein. There can be no assurance, moreover, that our opinion will be accepted by the Service or, if challenged, by a court.

Based solely on and subject to the limitations, qualifications, exceptions and assumptions set forth herein and 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 Prospectus Supplement under the caption "U.S. Federal Income Tax Considerations" does not purport to discuss all possible U.S. federal income tax considerations relevant to the ownership and disposition of the Notes, such discussion constitutes, in all material respects, a fair and accurate summary of the U.S. federal income tax considerations relevant to the ownership and disposition of the Notes.

Except as expressly set forth above, we express no other opinion. This opinion is furnished to you solely for your benefit in connection with the transactions described herein and is not to be relied upon for any other purpose or by anyone else without our prior written consent. 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 or the impact of any information, document, certificate, record, statement, representation, covenant, or assumption relied upon herein that becomes incorrect or untrue.

| Re: | <u>Southern Copper Corporation [●]% Senior Notes due 20[●]</u> |

---

Ladies and Gentlemen:

We have acted as special United States counsel to Southern Copper Corporation, a Delaware corporation (the "Company"), in connection with the Underwriting Agreement, dated [●], 2026 (the "Underwriting Agreement"), between you, as underwriters (the "Underwriters"), and the Company, relating to the sale by the Company to the Underwriters of the Company's $[●] aggregate principal amount of [●]% Senior Notes due 20[●] (the "Securities") to be issued under the Indenture, dated as of April 16, 2010 (the "Base Indenture"), between the Company and Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association), as trustee (in such capacity, the "Trustee"), as supplemented by the Seventh Supplemental Indenture, dated as of [●], 2026, between the Company and the Trustee.

This letter is being furnished to you pursuant to Section [7(d)] of the Underwriting Agreement. Neither the delivery of this letter nor anything in connection with the preparation, execution or delivery of the Underwriting Agreement or the transactions contemplated thereby is intended to create or shall create an attorney-client relationship with you or any other recipient of this letter.

Exhibit A-3<br>

------

In the above capacity, we have reviewed (i) the registration statement on Form S-3 (File No. 333-[●]) of the Company relating to the Securities and other securities of the Company filed on [●], 2026, with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933 (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) incorporated by reference into the registration statement at the Effective Time (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 [●], 2026 (the "Base Prospectus"), which forms a part of and is included in the Registration Statement; (iii) the preliminary prospectus supplement, dated [●], 2026 (together with the Base Prospectus and the Incorporated Documents incorporated by reference as of the Applicable Time (as defined below), 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 [●], 2026 (the "Prospectus Supplement" and, together with the Base Prospectus and the Incorporated Documents incorporated by reference as of the date of the Prospectus Supplement and the date hereof, 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 by the Company pursuant to the Securities Exchange Act of 1934 (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 (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.

In addition, we have participated in conferences with officers and other representatives of the Company, Mexican and Peruvian counsel for the Company, representatives of the independent registered public accountants of the Company and you and your counsel, at which the contents of the Registration Statement, the Prospectus, the 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 have assumed the accuracy of the translations or summaries furnished to us of any documents written in any language other than English. In addition, certain of the records and documents we reviewed were governed by the laws of Mexico and Peru or other jurisdictions other than the State of New York, and, accordingly, we necessarily relied upon the officers, employees and other representatives and agents of the Company and its Mexican and Peruvian counsel and other persons, as needed, in evaluating such records and documents. 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 Disclosure Package and have made no independent check or verification thereof (except to the limited extent referred to in paragraph [8] of our opinion letter to you dated the date hereof and our opinion letter to you, dated the date hereof, relating to the discussion in the Disclosure Package and the Prospectus Supplement under the heading "United States Federal Income Tax Considerations".

Exhibit A-3<br>

------

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 or any interactive data file, in each case 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 or any interactive data file, in each case included or incorporated by reference therein or excluded therefrom, the report of management's assessment of the effectiveness of internal control over financial reporting or the auditors' report on the effectiveness of the Company's internal control over financial reporting, the technical report summaries and the information contained in or derived from the technical report summaries of or attributable to the persons or entities whose consents are filed as exhibits to the Registration Statement, or the statements contained in the exhibits to the Registration Statement, including the Form T-1 or the statements contained in the exhibits to the Incorporated Documents). In addition, on the basis of the foregoing, no facts have come to our attention that have caused us to believe that the Disclosure Package, as of the Applicable Time, 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 or any interactive data file, in each case included or incorporated by reference therein or excluded therefrom, the report of management's assessment of the effectiveness of internal control over financial reporting or the auditors' report on the effectiveness of the Company's internal control over financial reporting, the technical report summaries and the information contained in or derived from the technical report summaries of or attributable to the persons or entities whose consents are filed as exhibits to the Registration Statement, or the statements contained in the exhibits to the Registration Statement, including the Form T-1 or the statements contained in the exhibits to the Incorporated Documents).

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 [[●] p.m. (Eastern time)] on [●], 2026 and (iii) "Disclosure Package" means the Preliminary Prospectus, as amended and supplemented by the Free Writing Prospectus.

This letter is being furnished only to you and is solely for your 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 or entity for any purpose, including any other person or entity that acquires any Securities or that seeks to assert your rights in respect of this letter (other than your successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

specified in the Underwriting Agreement referred to below

We have acted as special Mexican counsel to Southern Copper Corporation (the "<u>Company</u>") acting exclusively for the benefit of its Peruvian branch Southern Peru Copper Corporation, Sucursal del Perú, in connection with the underwriting agreement dated [●], 2026 (the "<u>Underwriting Agreement</u>"), executed among you, as Representatives of the several underwriters named therein (the "<u>Underwriters</u>"), and the Company, and the preparation of the registration statement on Form S-3 with file number [●] (the "<u>Registration Statement</u>"), including the prospectus dated [●], 2026, incorporated by reference therein (the "<u>Base Prospectus</u>"), as supplemented by the preliminary prospectus dated [●], 2026 (including the documents incorporated by reference therein, the "<u>Preliminary Prospectus Supplement</u>"), the pricing term sheet dated [●], 2026 (together with the Base Prospectus and the Preliminary Prospectus Supplement, the "<u>Disclosure Package</u>"), and the final prospectus supplement dated [●], 2026 (including the documents incorporated by reference therein, the "<u>Final Prospectus Supplement</u>"), in each case relating to the offer and sale by the Company of USD$[●] aggregate principal amount of the Company's [●]% Notes due [●] (the "<u>Notes</u>").

Capitalized terms used and not otherwise defined herein, shall have the meanings ascribed to such terms in the Underwriting Agreement. This letter is delivered to you pursuant to Section [●] of the Underwriting Agreement.

Because the primary purpose of our professional engagement was not to establish or confirm factual matters or financial or accounting matters and because of the non-legal character of most of the statements contained in the Disclosure Package and the Final Prospectus Supplement, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Disclosure Package and the Final Prospectus Supplement 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 other financial and accounting data included in the Disclosure Package and the Final Prospectus Supplement, and we have not examined the accounting and financial records from which such financial statements, and financial or accounting data are derived.

Exhibit B-1<br>

We have not otherwise undertaken any procedures that were intended or likely to elicit information concerning the accuracy, completeness or fairness of the statements made in the Disclosure Package and the Final Prospectus Supplement.

Based on our participation in the aforementioned conversations, our understanding of applicable Mexican law and the experience we have gained in our practice in in the United Mexican States ("<u>Mexico</u>") thereunder, without any independent verification, we advise you that no information has come to our attention that causes us to believe that (i) the Registration Statement (including the documents incorporated by reference therein), on the date of the Underwriting Agreement, 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 Disclosure Package, as of [●] pm (New York City time) on [●], 2026, 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 or (iii) the Final Prospectus Supplement, as of its date or as of the date hereof, 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, in each case other than the financial statements and financial and accounting data included therein, as to which we express no view.

This letter is limited to Mexican federal laws as in effect on the date hereof and shall in no way be construed as stating any view, express or implied, based upon the laws (including securities laws) of any jurisdiction other than Mexico, the interpretation thereof or the practice thereunder, with respect to which we are not qualified to express any views.

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 "<u>Company</u>"), in connection with its offer and sale of US$[●] [●]% notes due 20[●] (the "<u>Offered Securities</u>"), pursuant to an Underwriting Agreement dated [●], 2026, entered into by and among the Company and you, as Representatives of the several Underwriters (the "<u>Underwriting Agreement</u>").

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. [●]) relating to the Offered Securities and other securities of the Company filed by the Company with the U.S. Securities and Exchange Commission on [●], 2026 (the "<u>Registration Statement</u>"), (ii) the prospectus, dated [●], 2026, which forms a part of and is included in the Registration Statement (the "<u>Base Prospectus</u>"), (iii) the preliminary prospectus supplement, dated [●], 2026 (together with the Base Prospectus, the "<u>Preliminary Prospectus</u>"), relating to the Offered Securities, and (iv) the prospectus supplement, dated [●], 2026, relating to the Offered Securities (the "Pr<u>ospectus Supplement</u>" and, together with the Base Prospectus, the "<u>Prospectus</u>"). 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 and Mexican 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 nor have independently verified 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, on the date of the Underwriting Agreement, 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 (a) 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; and (b) we do not express any belief with respect to the financial statements or other financial or accounting data contained in or omitted from the Registration Statement, the Prospectus or the General Disclosure Package.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(D)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; any Taxes imposed solely because the Holder or beneficial owner fails to comply with any certification, identification, information, documentation or other reporting requirement concerning the nationality, residence or identity of the Holder or beneficial owner or connection of the Holder or beneficial owner with a Taxing Jurisdiction if compliance is required by law or regulation of the Taxing Jurisdiction or by an applicable income tax treaty to which a Taxing Jurisdiction is a party, as a precondition to exemption from, or reduction in the rate of, the Tax, and the Company has given the Holders of Notes at least 30 days' notice prior to the first payment date with respect to which such certification, identification, information, documentation or reporting requirement is required to the effect that Holders will be required to provide such certification, identification, information, documentation or reporting requirement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(E)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; any Taxes with respect to a Note presented for payment more than thirty (30) days after the date on which the payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders of Notes, whichever occurs later, except to the extent that the Holder of such Note would have been entitled to such Additional Amounts on presenting such Note for payment on any date during such 30-day period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(G)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; any Taxes imposed on any payment on a Note to a Holder thereof that is a fiduciary or partnership (including an entity treated as a partnership for tax purposes) or a person other than the sole beneficial owner of any such payment, but only to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of the payment would not have been entitled to the Additional Amounts had the beneficiary, settlor, member or beneficial owner been the Holder of the Note; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(H)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; any combination of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company will also pay any stamp, administrative, court, documentary, excise or similar Taxes arising in a relevant Taxing Jurisdiction in connection with the Notes and will indemnify the Holders for any such Taxes paid by Holders. The Company will provide the Trustee with documentation evidencing the payment of Taxes in respect of which the Company or SPCC has paid any Additional Amount or the assumption of the payment of any withholding of Taxes. The Company will make copies of such documentation available to the Holders of the Notes upon written request. The Trustee shall conclusively rely on such documentation and shall have no duty to investigate, verify or monitor the payment, withholding or remittance of any such Taxes or Additional Amounts. In addition, the Company or SPCC will pay any Peruvian value added tax that may be imposed on a payment of interest on the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the event that Additional Amounts actually paid with respect to the Notes pursuant to this Section 2.8 are based on rates of deduction or withholding of Taxes in excess of the appropriate rate applicable to the Holder of such Notes, and as a result thereof such Holder is entitled to make a claim for a refund or credit of such excess from the authority imposing such withholding Tax, then such Holder shall, by accepting such Notes, be deemed to have assigned and transferred all right, title and interest to any such claim for a refund or credit of such excess to the Company. However, by making such assignment, the Holder makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company, through SPCC, will pay promptly when due any present or future stamp, court or documentary taxes or any excise or property taxes, charges or similar levies that arise in any jurisdiction from the execution, delivery, registration or enforcement of each Note or any other document or instrument referred to in the Indenture or such Note, excluding any such taxes, charges or similar levies imposed by any jurisdiction that is not a Taxing Jurisdiction except those resulting from, or required to be paid in connection with, the enforcement of such Note or any other such document or instrument after the occurrence and during the continuance of any Event of Default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company, through SPCC, intends to assume the withholding of any Peruvian taxes and duties from interest on, and other applicable payments on or with respect to, the Notes at a rate of 4.99% as applicable and to pay Additional Amounts or to assume the payment of any such withholding, subject to the conditions above, with respect thereto for so long as the Notes are held through DTC or its nominee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Any reference in the Indenture or the Notes to principal, premium, interest or any other amount payable in respect of the Notes by the Company will be deemed also to refer to any Additional Amount that may be payable with respect to that amount under the obligations referred to in this Section 2.8.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Trustee shall have no responsibility or duty to determine whether any Additional Amounts are payable or owed, or whether any Taxes have been paid, withheld, remitted or otherwise satisfied by the Company or any Holder.

Section 2.9.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Redemption</u>. The Notes are subject to redemption at the option of the Company as set forth in the forms of Note attached hereto as Exhibit A.

In case of any such consolidation, merger conveyance or transfer (other than a lease), such successor corporation will succeed to and be substituted for the Company as obligor on the Notes, with the same effect as if it had been named in this Seventh Supplemental Indenture as such obligor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For purposes of this Section 2.13, the conveyance or transfer of all the property of one or more Subsidiaries of the Company which property, if held by the Company instead of such Subsidiaries, would constitute all or substantially all the property of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all the property of the Company.

Section 2.14.&nbsp;&nbsp;&nbsp;&nbsp; <u>Financial Calculations</u>.

If any Applicable Metric is determined by reference to the greater of a fixed amount, or the numerical permission, and a percentage of Consolidated Net Tangible Assets (the "grower permission") and the grower permission of the Applicable Metric exceeds the applicable numerical permission at any time, the numerical permission shall be deemed to be increased to the highest amount of the grower permission reached from time to time and shall not subsequently be reduced as a result of any decrease in the grower permission. "Applicable Metric" means any financial covenant or financial ratio or incurrence-based permission, test, basket or threshold in the Indenture (including any financial definition or component thereof and any financial ratio, test, basket or threshold or permission based on the calculation of Consolidated Net Tangible Assets), any default event of default or other relevant breach of the Indenture.

Section 2.15.&nbsp;&nbsp;&nbsp;&nbsp; <u>Events of Default</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The term "Event of Default" with respect to the Notes shall mean

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; default in the payment of the principal of any note issued pursuant to this Seventh Supplemental Indenture after any such principal becomes due in accordance with the terms thereof, upon redemption or otherwise; or default in the payment of any interest in respect of such Notes if such default continues for 30 days after any such interest becomes due in accordance with the terms hereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp; failure to observe or perform any other covenant or agreement contained in the Notes issued pursuant to this Seventh Supplemental Indenture, and such failure continuing for 90 days after notice, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 33<sup>1</sup>∕3% in aggregate principal amount of the outstanding Notes, specifying such failure and requiring it to be remedied and stating that such notice constitutes a notice of default under this Seventh Supplemental Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp; a decree or order by a court having jurisdiction shall have been entered adjudging the Company or any of its Significant Subsidiaries as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, *concurso mercantil* or *quiebra* of or by the Company or any of its Significant Subsidiaries and such decree or order shall have continued undischarged or unstayed for a period of 120 days; or a decree or order of a court having jurisdiction for the appointment of a receiver or liquidator or *sindico* or *conciliador* for the liquidation or dissolution of the Company or any of its Significant Subsidiaries shall have been entered, and such decree or order shall have continued undischarged and unstayed for a period of 120 days; *provided*, *however*, that any Significant Subsidiary may be liquidated or dissolved if, pursuant to such liquidation or dissolution, all or substantially all of its assets are transferred to the Company or another Significant Subsidiary of the Company; or

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the Company or any of its Significant Subsidiaries shall institute any proceeding to be adjudicated as voluntary bankrupt, or shall consent to the filing of a bankruptcy proceeding against it, or shall file a petition or answer or consent seeking reorganization, *concurso mercantil* or *quiebra*, or shall consent to the filing of any such petition, or shall consent to the appointment of a receiver or liquidator or *sindico* or *conciliador* or trustee or assignee in bankruptcy or insolvency of it or its property.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If an Event of Default specified in (a)(iii) or (a)(iv) above shall occur, the maturity of all outstanding Notes shall automatically be accelerated and the principal amount of the Notes, together with accrued interest thereon, shall be immediately due and payable without any further action on the part of the Trustee or any Holder. If any other Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 33<sup>1</sup>∕3% of the aggregate principal amount of the Notes then outstanding may, by written notice to the Company (and to the Trustee if given by Holders), declare the principal amount of the applicable Notes, together with accrued interest thereon, immediately due and payable. The right of the Holders to give such acceleration notice shall terminate if the event giving rise to such right shall have been cured before such right is exercised. Any such declaration may be annulled and rescinded by written notice from the Trustee or the Holders of a majority of the aggregate principal amount of the Notes then outstanding to the Company if all amounts then due with respect to the Notes are paid (other than amounts due solely because of such declaration) and all other defaults with respect to the Notes are cured.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Subject to the provisions of the Base Indenture and this Seventh Supplemental Indenture relating to the duties of the Trustee, in case the Company shall fail to comply with its obligations under this Seventh Supplemental Indenture or the Notes and such failure shall be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under the Seventh Supplemental Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee indemnity reasonably satisfactory to it against any loss, cost, liability, fee or expense. The Holders of a majority in aggregate principal amount of the outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, to the extent such action does not conflict with the provisions of this Seventh Supplemental Indenture or applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; No Holder of any note will have any right to institute any proceeding with respect to the Seventh Supplemental Indenture or the Notes or for any remedy thereunder, unless such Holder has previously given to the Trustee written notice of a continuing Event of Default and unless also the Holders of at least 33<sup>1</sup>∕3% in aggregate principal amount of the outstanding Notes shall have made a written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee, such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against any loss, cost, liability, fee or expense, the Trustee for 60 days after receipt of such notice has failed to institute any such proceeding and no direction inconsistent with such request shall have been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the outstanding Notes. However, such limitations do not apply to a suit individually instituted by a Holder of a note for enforcement of payment of the principal of, or interest on, such note on or after respective due dates expressed in such note.

The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If the Company exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect to the Notes. If the Company exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in Sections 2.15(a)(ii) (with respect to the covenants identified in clause (a) above), 2.15(a)(iii) and 2.15(a)(iv) (with respect only to Significant Subsidiaries in the case of Section 2.15(a)(iv)).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Notwithstanding clauses (a) and (b) above, the Company's obligations with respect to Sections 3.05, 3.06, 3.07, and 12.09 of the Base Indenture, in each case with respect to the Notes only, shall survive until the Notes have been paid in full.

Section 2.18.&nbsp;&nbsp;&nbsp;&nbsp; <u>Amendments</u>. In addition to the restrictions set forth in Section 14.02 of the Base Indenture, without the consent or affirmative vote of each Holder of Notes affected thereby, an amendment of this Seventh Supplemental Indenture or the Base Indenture (with respect to the Notes only) may not reduce the premium payable upon a Change of Control Triggering Event or, at any time after a Change of Control Triggering Event has occurred, change the time at which the Change of Control Offer relating thereto must be made or at which the Notes must be repurchased pursuant to such Change of Control Offer.

[FORM OF REVERSE SIDE OF SECURITY]

5.350% Notes due 2036

1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Indenture</u>.

This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of April 16, 2010, as supplemented by a Seventh Supplemental Indenture, dated June 24, 2026 (as so supplemented, herein called the "Indenture"), between the Company and Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association), a national banking association, as trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $[1,250,000,000].

The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 <u>U</u>.<u>S</u>.<u>C</u>. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the "TIA"). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a statement of those terms.

2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Method of Payment</u>.

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on June 9 or December 9, as the case may be, next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. Payments on the Securities will be made at the office or agency of the Paying Agent and Registrar within the city of Minneapolis, Minnesota unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register.

3. <u>Paying Agent and Registrar</u>.

Initially, the Trustee will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

------

4. <u>Redemption</u>.

The Company will not be permitted to redeem the Notes before their stated maturity, except as set forth below. The Notes will not be entitled to the benefit of any sinking fund—meaning that the Company will not deposit money on a regular basis into any separate account to repay the Notes. In addition, Holders will not be entitled to require the Company to repurchase Notes before the stated maturity, except as set forth below under "—Repurchase of Securities at the Option of Holders upon Change of Control Triggering Event."

*Make-Whole Redemption*. Prior to March 24, 2036 (three months prior to the maturity date) (the "Par Call Date"), the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of a principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

"Treasury Rate" for this purpose means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily)—H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the "Remaining Life"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the applicable Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the applicable Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the applicable Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the applicable Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

------

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the relevant Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Issuer's actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

*Par Redemption*. On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date. Notwithstanding the foregoing, payments of interest on the Notes will be payable to the Holders of those Notes registered as such at the close of business on the relevant record dates according to the terms and provisions of the Indenture, subject to the procedures of DTC.

------

*Redemption for Taxation Reasons*. If, as a result of the adoption of any new laws, rules, regulations or interpretations, or any amendment to, or change in, the laws (or any rules or regulations thereunder) of any Taxing Jurisdiction affecting taxation, or any amendment to, or change in official position by a competent authority in any Taxing Jurisdiction with respect to, an official interpretation or application of such laws, rules or regulations, which adoption, change or amendment is announced and becomes effective on or after the later of (a) the date on which the Notes the Company is offering are issued and (b) the date the relevant Taxing Jurisdiction becomes a Taxing Jurisdiction, the Company or SPCC has assumed or has become obligated or will assume or become obligated, in each case, after taking all reasonable measures to avoid this requirement (including, if necessary, the designation of a different paying agent), to pay Additional Amounts or to assume any withholding payments in excess of those attributable to (i) a Peruvian withholding tax rate of 4.99%, or (ii) the applicable withholding tax rate in a relevant Taxing Jurisdiction in effect on the date the relevant Taxing Jurisdiction becomes a Taxing Jurisdiction on or with respect to the Notes or on payments of interest on or other amounts on or with respect to the Notes, then, at the Company's option, all, but not less than all, of the Notes may be redeemed at any time on giving not less than 30 nor more than 60 days' notice to the Holders (with a copy to the Trustee), at a redemption price equal to 100% of the outstanding principal amount, plus accrued and unpaid interest and any Additional Amounts due thereon up to, but excluding, the date of redemption; provided, however, that (1) no notice of redemption for tax reasons may be given earlier than ninety (90) days prior to the earliest date on which the Company would be obligated to pay these Additional Amounts if a payment on the Notes were then due, and (2) at the time such notice of redemption is given such obligation to pay such Additional Amounts remains in effect or is to become effective.

Prior to giving any notice of redemption pursuant to this provision, the Company will deliver to the Trustee:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) an officer's certificate signed by one of the Company's duly authorized representatives stating that the Company is entitled to effect the redemption and setting forth a statement of facts showing that the conditions precedent to the Company's right to redeem have occurred, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) an opinion of a tax advisor of recognized standing qualified in the relevant Taxing Jurisdiction to the effect that the Company or SPCC has or will assume or become obligated to pay such Additional Amounts or assume any withholding payment as a result of such change or amendment, as described above.

The notice of redemption pursuant to this provision, once delivered to the Holders, will be irrevocable. The Trustee shall conclusively rely on the statements set forth in the notice, certificate and tax advisor opinion without independent verification thereof.

*Open Market Purchases*. The Company may at any time purchase Notes in the open market or otherwise at any price.

*Offers to Purchase.* In connection with any tender offer for, or other offer to purchase, the Notes, including upon a Change of Control Triggering Event, if Holders of not less than 85.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer (or other offer to purchase) and the Company, or any third party making such a tender offer (or other offer to purchase) in lieu of the Company, purchases all of the Notes validly tendered and not withdrawn by such Holders, all of the Holders of the outstanding Notes will be deemed to have consented to such tender (or other offer to purchase), and accordingly the Company will have the right, upon not less than 10 nor more than 60 days' prior notice, given not more than 30 days following such tender offer (or other offer) early results or expiration date, at the discretion of the Company, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to the price paid to each other Holder (excluding any early tender, incentive or similar fee) in such tender offer (or other offer to purchase), plus, to the extent not included in the tender offer payment (or payment pursuant to another offer to purchase), accrued and unpaid interest, if any, to the date of redemption. In determining whether the Holders of at least 85.0% of the aggregate principal of the then outstanding Notes have validly tendered and not withdrawn Notes in a tender offer or other offer to purchase, such calculation shall include all Notes owned by an Affiliate of any of the Company and the parent (notwithstanding any provision of the Indenture to the contrary).

5. <u>Notice of Redemption</u>.

This paragraph 5 supplements and, to the extent inconsistent therewith, supersedes the corresponding provisions of the Base Indenture relating to notice of redemption in Section 4.03; provided that Section 4.05 of the Base Indenture shall continue to apply to the Notes in its entirety.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary's procedures) at least 10 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

All notices of redemption shall state: (1) the Redemption Date; (2) the redemption price and the amount of any accrued interest payable as provided in Section 4.05 of the Base Indenture; (3) whether or not the Company is redeeming all outstanding Notes; (4) if the Company is not redeeming all outstanding Notes, the aggregate principal amount of Notes that the Company is redeeming and the aggregate principal amount of Notes that will be outstanding after the partial redemption; (5) if the Company is redeeming only part of a Note, the notice that relates to that Note shall state that on and after the Redemption Date, upon surrender of that Note, the Holder will receive, without charge, a new Note or Notes of authorized denominations for the principal amount of the Note remaining unredeemed; (6) that on the Redemption Date the redemption price and any accrued interest payable to the Redemption Date as provided in Section 4.05 of the Base Indenture will become due and payable in respect of each Note, or the portion of each Note, to be redeemed, and, unless the Company defaults in making the redemption payment, that interest on each Note, or the portion of each Note, to be redeemed, will cease to accrue on and after the Redemption Date; (7) the place or places where a Holder must surrender the Holder's Notes for payment of the redemption price; and (8) the CUSIP or ISIN number, if any, listed in the notice or printed on the Notes, and that no representation is made as to the accuracy or correctness of such CUSIP or ISIN number.

------

Any redemption and notice thereof pursuant to the Indenture may, in the Company's discretion, be subject to the satisfaction of one or more conditions precedent. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Company's discretion, the Redemption Date may be delayed up to five Business Days (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) for such conditions to be satisfied (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the Redemption Date, or by the Redemption Date as so delayed. The Company shall provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

Failure to give notice or any defect in the notice to any Holder shall not affect the validity of notice to any other Holder.

If the Company is not redeeming all outstanding Notes, the Trustee shall select the Notes to be redeemed in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if such Notes are not then listed on a national securities exchange, on a pro rata basis, by lot or any other method as the Trustee shall deem fair and appropriate (subject to the procedures of DTC). The Trustee shall make the selection from the outstanding Notes not previously called for redemption. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount of the Notes to be redeemed. In the event of a partial redemption by lot, the Trustee shall select the particular Notes to be redeemed not less than 10 nor more than 60 days prior to the relevant Redemption Date from the outstanding Notes not previously called for redemption.

Subject to the minimum denomination requirements of Section 2.7 of the Seventh Supplemental Indenture, the Trustee may select for redemption portions (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of the principal amount of Notes that have denominations larger than $2,000. No Notes of a principal amount of $2,000 or less will be redeemed in part.

If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note (or through book-entry transfer for any global notes).

------

6. <u>Sinking Fund and Highly Leveraged Transactions</u>.

The Securities are not subject to any sinking fund. The Indenture does not include any debt covenants or other provisions which afford holders of the Securities protection in the event of a highly leveraged transaction.

7. <u>Repurchase of Securities at the Option of Holders upon Change of Control Triggering Event</u>.

Upon a Change of Control Triggering Event, Holders of Notes will have the right, subject to certain conditions specified in the Indenture, to cause the Company to repurchase all or any part of the Securities of such Holder at a purchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the date of purchase) as provided in, and subject to the terms of, the Indenture.

8. <u>Denominations; Transfer; Exchange</u>.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and in integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the security register, upon surrender of this Security for registration of transfer at the Registrar accompanied by a written request for transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

9. <u>Persons Deemed Owners</u>.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

------

10. <u>Amendment, Waiver</u>.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

11. <u>Defaults and Remedies</u>.

If an Event of Default with respect to Securities shall occur and be continuing, the principal of the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

Phoenix, June 25, 2026 - Southern Copper Corporation (NYSE and LSE: SCCO) announced today that it has completed a public offering of US$1,250,000,000 million 5.350% Notes due 2036.
