NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1 — DESCRIPTION OF THE BUSINESS:

In the opinion of Southern Copper Corporation, (the “Company” or “SCC”), the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to state fairly the Company’s financial position as of June 30, 2012 and the results of operations, comprehensive income and cash flows for the three and six months ended June 30, 2012 and 2011. The results of operations for the three and six months ended June 30, 2012 and 2011 are not necessarily indicative of the results to be expected for the full year. The December 31, 2011 balance sheet data was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles in the United States of America (U.S. GAAP). The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements at December 31, 2011 and notes included in the Company’s 2011 annual report on Form 10-K.

NOTE 2 — SHORT-TERM INVESTMENTS:

Short-term investments were as follows ($ in millions):

Weighted average interest rate |  | 1.01 | % | 1.37 | %

Weighted average interest rate |  | 0.54 | % | 0.58 | %
Total |  | $ | 373.7 |  | $ | 521.9 |

Trading securities: consist of bonds issued by public companies. Each financial instrument is independent of the others. The Company has the intention to sell these bonds in the short-term.

Available for sale investments consist of securities issued by public companies. Each security is independent of the others and at June 30, 2012 and December 31, 2011, included corporate bonds and asset and mortgage backed obligations. As of June 30, 2012 and December 31, 2011, gross unrealized gains and losses on available for sale securities were not material.

Related to these investments the Company earned interest, which was recorded as interest income in the condensed consolidated statement of earnings. Also the Company redeemed some of these securities and recognized gains (losses) due to changes in fair value, which were recorded as gain on short-term investment in the condensed consolidated statement of earnings.

NOTE 3 - INVENTORIES:

Inventories were as follows:

(in millions) |  | At June 30, 2012 |  | At December 31, 2011 |
Inventory, current: |  |  |  |  |
Metals at lower of average cost or market: |  |  |  |  |
Finished goods |  | $ | 110.8 |  | $ | 93.3 |
Work-in-process |  | 230.5 |  | 296.1 |
Supplies at average cost |  | 284.3 |  | 262.5 |
Total current inventory |  | $ | 625.6 |  | $ | 651.9 |
Inventory, long-term |  |  |  |  |
Long-term leach stockpiles |  | $ | 182.2 |  | $ | 123.0 |

During the six months ended June 30, 2012 and 2011 total leaching costs capitalized as long-term inventory of leachable material amounted to $101.2 million and $54.1 million, respectively. Long-term leaching inventories recognized as cost of sales amounted to $35.3 million and $23.6 million for the six months ended June 30, 2012 and 2011, respectively.

NOTE 4 — INCOME TAXES:

The income tax provision and the effective income tax rate for the first six months of 2012 and 2011 were as follows ($ in millions):

|  | 2012 |  | 2011 |
Income tax provision |  | $ | 628.7 |  | $ | 540.0 |
Effective income tax rate |  | 35.1 | % | 32.1 | %

These provisions include income taxes for Peru, Mexico and the United States. The increase in the effective tax rate in the first six months of 2012 from the tax rate in the 2011 period is principally caused by the new special mining tax in Peru, see below, and by the increase in dividends remitted from Mexico in 2012, which required a supplemental provision for U.S. income tax.

For United States federal income tax reporting the operating results of SCC are included in the Americas Mining Corporation (“AMC”) U.S. federal income tax return. In accordance with paragraph 30-27 of ASC 740-10-30, current and deferred taxes are allocated to members of the AMC group as if each were a separate taxpayer. SCC provides current and deferred income taxes as if it was a separate filer.

Special Mining Tax

In September 2011, the Peruvian government enacted a new tax for the mining industry. This tax is based on operating income and its rate ranges from 2% to 8.4%. It begins at 2% for the first 10% of operating income and for each additional 5% of operating income is increased by 0.4% until 85% of operating income is reached. The Company has accrued $28.4 million for the special mining tax and is included as part of the income tax provision for the first six months of 2012.

Accounting for Uncertainty in Income Taxes:

The Company files tax returns in Peru, the United States and in Mexico. These tax returns are examined by the tax authorities of those countries. It is reasonably possible that during the next 12 months there could be an increase of approximately $30 to $50 million in the Company’s unrecognized tax benefits due to expected activity from tax examinations and audits by the tax authorities.

NOTE 5 — PROVISIONALLY PRICED SALES:

At June 30, 2012, the Company has recorded provisionally priced sales of copper at average forward prices per pound, and molybdenum at the June 30, 2012 market price per pound. These sales are subject to final pricing based on the average monthly

London Metal Exchange (“LME”) or New York Commodities Exchange (“COMEX”) copper prices and Dealer Oxide molybdenum prices in the future month of settlement.

Following are the provisionally priced copper and molybdenum sales outstanding at June 30, 2012:

Copper (million lbs.) |  | Priced at (per pound) |  | Month of Settlement |
26.2 |  | $ | 3.491 |  | July 2012 |
21.6 |  | 3.490 |  | August 2012 |
47.8 |  | $ | 3.491 |  |  |

Molybdenum (million lbs.) |  | Priced at (per pound) |  | Month of Settlement |
3.4 |  | $ | 13.13 |  | July 2012 |
3.4 |  | 13.13 |  | August 2012 |
2.2 |  | 13.13 |  | September 2012 |
9.0 |  | $ | 13.13 |  |  |

Management believes that the final pricing of these sales will not have a material effect on the Company’s financial position or results of operations.

NOTE 6 — DERIVATIVE INSTRUMENTS:

As part of its risk management policy, the Company occasionally uses derivative instruments to (i) safeguard the corporate assets, (ii) insure the value of its future revenue stream, and (iii) lessen the impact of unforeseen market swings of its sales revenues. To comply with these objectives the Company, from time to time, enters into commodity price derivatives, interest rate derivatives, exchange rate derivatives and other instruments. The Company does not enter into derivative contracts unless it anticipates a future activity that is likely to occur that will result in exposing the Company to market risk.

Copper hedges:

In 2011, the Company entered into copper swaps and zero cost collar derivative contracts to reduce price volatility and to protect its sales value as shown below. These transactions meet the requirements of hedge accounting. The realized gains and losses from these derivatives were recorded in net sales on the condensed consolidated statement of earnings and included in operating activities on the condensed consolidated statement of cash flow.

The following table summarizes the copper derivative activity related to copper sales transactions realized in the second quarter and first six months of 2012 and 2011, respectively:

|  | Second quarter |  | First six months |
|  | 2012 |  | 2011 |  | 2012 |  | 2011 |
Zero cost collar contracts: |  |  |  |  |  |  |  |  |
Pounds (in millions) |  | — |  | 105.8 |  | 46.3 |  | 211.6 |
Average LME cap price |  | — |  | $ | 4.84 |  | $ | 5.18 |  | $ | 4.84 |
Average LME floor price |  | — |  | $ | 3.02 |  | $ | 3.50 |  | $ | 3.02 |
Swap contracts: |  | — |  |  |  |  |  |  |
Pounds (in millions) |  | — |  | 112.4 |  | — |  | 232.0 |
Weighted average COMEX price |  | — |  | $ | 4.08 |  | — |  | $ | 4.08 |
Realized loss on copper derivatives (in millions) |  | — |  | $ | 8.6 |  | — |  | $ | 44.3 |

The hedge instruments are based on LME copper prices. The Company performed statistical analysis on the difference between the average monthly copper price on the LME and the COMEX exchanges and determined that the correlation coefficient is greater than 0.999. Based on this analysis, the Company considers that the LME underlying price matches its sales priced at COMEX prices. These cash flow hedge relationships qualify as critical matched terms hedge relationships and as a result have no ineffectiveness. The Company performs periodic quantitative assessments to confirm that the relationship was highly effective and that the ineffectiveness was de minimis.

Table of Contents

During the second quarter of 2012 and as of June 30, 2012, the Company did not hold copper derivative contracts.

Transactions under these metal price protection programs are accounted for as cash flow hedges under ASC 815-30 “Derivatives and Hedging-Cash Flow Hedges” as they meet the requirements for this treatment and are adjusted to fair market value based on the metal prices as of the last day of the respective reporting period with the gain or loss recorded in other comprehensive income until settlement, at which time the gain or loss, if realized, is reclassified to net sales in the condensed consolidated statements of earnings.

NOTE 7 - ASSET RETIREMENT OBLIGATION:

The Company maintains an estimated asset retirement obligation for its mining properties in Peru, as required by the Peruvian Mine Closure Law. In accordance with the requirements of this law the Company’s closure plans were approved by the Peruvian Ministry of Energy and Mines (“MINEM”). As part of the closure plans, commencing in January 2010 the Company is required to provide annual guarantees of $2.6 million over a 34 year period to furnish the funds for the asset retirement obligation. In the near-term future the Company has pledged the value of its Lima office complex as support for this obligation. The accepted value of the Lima office building, for this purpose, is $17 million. The closure cost recognized for this liability includes the cost, as outlined in its closure plans, of dismantling the Toquepala and Cuajone concentrators, the smelter and refinery in Ilo, and the shops and auxiliary facilities at the three units, including the Ilo marine trestle.

The following table summarizes the asset retirement obligation activity for the six months ended June 30, 2012 and 2011 (in millions):

NOTE 10 — COMMITMENTS AND CONTINGENCIES:

Environmental matters:

The Company has instituted extensive environmental conservation programs at its mining facilities in Peru and Mexico. The Company’s environmental programs include, among other features, water recovery systems to conserve water and minimize impact on nearby streams, reforestation programs to stabilize the surface of the tailings dams and the implementation of scrubbing technology in the mines to reduce dust emissions.

Environmental capital expenditures in the six months ended June 30, 2012 and 2011 were as follows (in millions):

|  | 2012 |  | 2011 |
Peruvian operations |  | $ | 2.1 |  | $ | 1.1 |
Mexican operations |  | 10.7 |  | 3.7 |
|  | $ | 12.8 |  | $ | 4.8 |

Peruvian operations: The Company’s operations are subject to applicable Peruvian environmental laws and regulations. The Peruvian government, through the Environmental Ministry conducts annual audits of the Company’s Peruvian mining and metallurgical operations. Through these environmental audits, matters related to environmental commitments, compliance with legal requirements, atmospheric emissions, and effluent monitoring are reviewed. The Company believes that it is in material compliance with applicable Peruvian environmental laws and regulations.

Peruvian law requires that companies in the mining industry provide for future closure and remediation. In accordance with the requirements of this law the Company’s closure plans were approved by MINEM. As part of the closure plans, the Company is providing guarantees to ensure that sufficient funds will be available for the asset retirement obligation. See Note 7, “Asset retirement obligation,” for further discussion of this matter.

Mexican operations: The Company’s operations are subject to applicable Mexican federal, state and municipal environmental laws, to Mexican official standards, and to regulations for the protection of the environment, including regulations relating to water supply, water quality, air quality, noise levels and hazardous and solid waste.

13

Table of Contents

The principal legislation applicable to the Company’s Mexican operations is the Federal General Law of Ecological Balance and Environmental Protection (the “General Law”), which is enforced by the Federal Bureau of Environmental Protection (“PROFEPA”). PROFEPA monitors compliance with environmental legislation and enforces Mexican environmental laws, regulations and official standards. PROFEPA may initiate administrative proceedings against companies that violate environmental laws, which in the most extreme cases may result in the temporary or permanent closing of non-complying facilities, the revocation of operating licenses and/or other sanctions or fines. Also, according to the federal criminal code, PROFEPA must inform corresponding authorities regarding environmental non-compliance.

On January 28, 2011, Article 180 of the General Law was amended. This amendment, gives an individual or entity the ability to contest administrative acts, including environmental authorizations, permits or concessions granted, without the need to demonstrate the actual existence of harm to the environment, natural resources, flora, fauna or human health, because it will be sufficient to argue that the harm may be caused.

In addition, on August 30, 2011, amendments to the Civil Federal Procedures Code (“CFPC”) were published in the Official Gazette and are now in force. These amendments establish three categories of collective actions, by means of which 30 or more people claiming injury derived from environmental, consumer protection, financial services and economic competition issues will be considered to be sufficient in order to have a legitimate interest to seek through a civil procedure restitution or economic compensation or suspension of the activities from which the alleged injury derived. The amendments to the CFPC may result in more litigation, with plaintiffs seeking remedies, including suspension of the activities alleged to cause harm.

On December 5, 2011, the Mexican Senate Chamber approved the Environmental Liability Federal Law, which establishes general guidelines in order to determine which environmental actions will be considered to cause environmental harm that will give rise to administrative responsibilities (remediation or compensations) and criminal responsibilities. Also economic fines could be established. This initiative has been returned to lower chamber for discussion and voting. The law will be in force once approved by the lower chamber and signed by the President.

In March 2010, the Company announced to the Mexican federal environmental authorities the closure of the copper smelter plant at San Luis Potosi. The Company has initiated a program for plant demolition and soil remediation with a budget of $35.7 million, of which the Company has spent $28.2 million through June 30, 2012. The program is expected to be completed by the end of 2013. The Company expects that once the site is remediated, the Company will be able to promote an urban development to generate a net gain on the disposal of the property.

The Company believes that all of its facilities in Peru and Mexico are in material compliance with applicable environmental, mining and other laws and regulations.

The Company also believes that continued compliance with environmental laws of Mexico and Peru will not have a material adverse effect on the Company’s business, properties, result of operations, financial condition or prospects and will not result in material capital expenditures.

Litigation matters:

Peruvian operations

Garcia Ataucuri and Others against SCC’s Peruvian Branch:

In April 1996, the Branch was served with a complaint filed in Peru by Mr. Garcia Ataucuri and approximately 900 former employees seeking the delivery of a substantial number of “labor shares” (acciones laborales) plus dividends on such shares, to be issued to each former employee in proportion to their time of employment with SCC’s Peruvian Branch.

The labor share litigation is based on claims of former employees for ownership of a portion of the labor shares that the plaintiffs state that the Branch did not issue during the 1970s until 1979 under a former Peruvian mandated profit sharing system. In 1971, the Peruvian government enacted legislation providing that mining workers would have a 10% participation in the pre-tax profits of their employing enterprises. This participation was distributed 40% in cash and 60% in an equity interest of the enterprise. In 1978, the equity portion, which was originally delivered to a mining industry workers’ organization, was set at 5.5% of pre-tax profits and was delivered mainly in the form of “labor shares” to individual workers. The cash portion was set at 4.0% of pre-tax earnings and was delivered to individual employees also in proportion to their time of employment with the Branch. In 1992, the workers’ participation was set at 8%, with 100% payable in cash and the equity participation was eliminated from the law.

In relation to the issuance of “labor shares” by the Branch in Peru, the Branch is a defendant in the following lawsuits:

14

Table of Contents

1) Mr. Garcia Ataucuri seeks delivery, to himself and each of the approximately 900 former employees of the Peruvian Branch, of the 3,876,380,679.65 old soles or 38,763,806.80 “labor shares” (acciones laborales), as required by Decree Law 22333 (a former profit sharing law), to be issued proportionally to each former employee in accordance with the time of employment of such employee with SCC’s Branch in Peru, plus dividends on such shares. The 38,763,806.80 labor shares sought in the complaint, with a face value of 100.00 old soles each, represent 100% of the labor shares issued by the Branch during the 1970s until 1979 for all of its employees during that period. The plaintiffs do not represent 100% of the Branch´s eligible employees during that period.

It should be noted that the lawsuit refers to a prior Peruvian currency called “sol de oro” or old soles, which was later changed to the “inti”, and then into today´s “nuevo sol”. One billion of old soles is equivalent to today’s one nuevo sol.

After lengthy proceedings before the civil courts in Peru on September 19, 2001, on appeal from the Branch (the 2000 appeal), the Peruvian Supreme Court annulled the proceedings noting that the civil courts lacked jurisdiction and that the matter had to be decided by a labor court.

In October 2007, in a separate proceeding initiated by the plaintiffs, the Peruvian Constitutional Court nullified the September 19, 2001 Peruvian Supreme Court decision and ordered the Supreme Court to decide again on the merits of the case accepting or denying the Branch’s 2000 appeal.

In May 2009, the Supreme Court rejected the 2000 appeal of the Branch affirming the adverse decision of the appellate civil court and lower civil court. While the Supreme Court has ordered SCC’s Peruvian Branch to deliver the labor shares and dividends, it has clearly stated that SCC’s Peruvian Branch may prove, by all legal means, its assertion that the labor shares and dividends were distributed to the former employees in accordance with the profit sharing law then in effect, an assertion which SCC’s Peruvian Branch continues to make. None of the court decisions state the manner by which the Branch must comply with the delivery of such labor shares or make a liquidation of the amount to be paid for past dividends and interest, if any.

On June 9, 2009, SCC’s Peruvian Branch filed a proceeding of relief before a civil court in Peru seeking the nullity of the 2009 Supreme Court decision and, in a separate proceeding, a request for a precautionary measure. The civil court rendered a favorable decision on the nullity and the precautionary measure, suspending the enforcement of the Supreme Court decision, for the reasons indicated above and other reasons. In February 2012, the Branch was notified that the civil court had reversed its decision regarding the nullity. The precautionary measure is still in effect. The Peruvian Branch has appealed the unfavorable decision before the superior court. In view of this, and the recent civil court decision, SCC´s Peruvian Branch continues to analyze the manner in which the Supreme Court decision may be enforced and what financial impact, if any, said decision may have.

2) In addition, there are filed against SCC’s Branch the following lawsuits, involving approximately 800 plaintiffs, which seek the same number of labor shares as in the Garcia Ataucuri case, plus interest, labor shares resulting from capital increases and dividends: Armando Cornejo Flores and others v. SCC’s Peruvian Branch (filed May 10, 2006); Alejandro Zapata Mamani and others v. SCC’s Peruvian Branch (filed June 27, 2008); Arenas Rodriguez and others, represented by Mr. Cornejo Flores, v. SCC’s Peruvian Branch (filed January 2009); Eduardo Chujutalli v. SCC’s Peruvian Branch (filed May 2011); Edgardo Garcia Ataucuri, in representation of 216 of SCC’s Peruvian Branch former workers, v. SCC’s Peruvian Branch (filed May 2011); Silvestre Macedo Condori v. SCC’s Peruvian Branch (filed June 2011); Juan Guillermo Oporto Carpio v. SCC’s Peruvian Branch (filed August 2011); Rene Mercado Caballero v. SCC’s Peruvian Branch (filed November 2011); Enrique Salazar Alvarez and others v. SCC’s Peruvian Branch (filed December 2011); Indalecio Carlos Perez Cano and others v. SCC Peruvian Branch (filed March 2012); Jesús Mamani Chura and others v. SCC’s Peruvian Branch (filed March, 2012) and Armando Cornejo Flores, in representation of 37 of SCC’s Peruvian Branch former workers v. SCC’s Peruvian Branch (filed March, 2012). SCC’s Peruvian Branch has answered the complaints and denied the validity of the claims.

SCC’s Peruvian Branch asserts that the labor shares were distributed to the former employees in accordance with the profit sharing law then in effect. The Peruvian Branch has not made a provision for these lawsuits because it believes that it has meritorious defenses to the claims asserted in the complaints. Additionally, the amount of this contingency cannot be reasonably estimated by management at this time.

Exploraciones de Concesiones Metalicas S.A.C. (“Excomet”):

In August 2009, a lawsuit was filed against SCC’s Branch by the former stockholders of Excomet. The plaintiffs allege that the acquisition of Excomet’s shares by the Branch is null and void because the $2 million purchase price paid by the Branch for the shares of Excomet was not fairly negotiated by the plaintiffs and the Branch. In 2005, the Branch acquired the shares of Excomet

15

Table of Contents

after lengthy negotiations with the plaintiffs, and after the plaintiffs, which were all of the stockholders of Excomet, approved the transaction in a general stockholders’ meeting. Excomet was at the time owner of a mining concession which forms part of the Tia Maria project. In October 2011, the civil court dismissed the case on the grounds that the claim had been barred by the statute of limitations. The plaintiff has appealed this decision before the superior court. At June 30, 2012, resolution of the appeal was pending.

Sociedad Minera de Responsabilidad Limitada Virgen Maria de Arequipa (SMRL Virgen Maria):

In August 2010, a lawsuit was filed against SCC’s Branch and others by SMRL Virgen Maria, a company which until July 2003 owned the mining concession Virgen Maria, which forms part of the Tia Maria project. SMRL Virgen Maria sold this mining concession in July 2003 to Excomet (see above noted case).

The plaintiff alleges that the sale of the mining concession Virgen Maria to Excomet is null and void because the persons who attended the shareholders’ meeting of SMRL Virgen Maria, at which the purchase was agreed upon, were not the real owners of the shares. The plaintiff is also pursuing the nullity of all the subsequent acts regarding the mining property (acquisition of the shares of Excomet by SCC’s Branch, noted above, and the sale of the concession to SCC’s Branch by Excomet). On October, 2011, the civil court dismissed the case on the grounds that the claim had been barred by the statute of limitations. The plaintiff has appealed this decision before the superior court. At June 30, 2012, resolution of the appeal was pending.

Omar Nunez Melgar:

In May 2011, Mr. Omar Nunez Melgar commenced a lawsuit against the Peruvian Mining and Metallurgical Institute (“INGEMMET”) and the MINEM challenging the denial of Mr. Nunez’s concession request that conflicted with SCC’s Branch’s Virgen Maria concession, which forms part of the Tia Maria concession. SCC’s Branch has been made a party to the proceedings as the owner of the Virgen Maria concession. SCC’s Branch has answered the complaint and denied the validity of the claim. As of June 30, 2012, this case remains open with no further developments.

The Company asserts that the lawsuits are without merit and is vigorously defending against these lawsuits.

Pasta de Conchos Accident:

On February 19, 2010, three widows of miners, who perished in the 2006 Pasta de Conchos accident, filed a complaint for damages in the United States District Court for the District of Arizona against the defendants, Grupo Mexico, AMC and SCC. The plaintiffs allege that the defendants’ purported failure to maintain a safe working environment at the mine amounted to a violation of several laws and treaties. The Company considers that the court does not have subject-matter jurisdiction over the plaintiffs’ claims and will defend itself vigorously. On April 13, 2010, the Company filed a motion to dismiss the plaintiffs’ complaint. On March 29, 2011, the District Court for the District of Arizona dismissed the case for lack of subject-matter jurisdiction. On April 5, 2011, the plaintiffs filed a notice of appeal in this case. At June 30, 2012, resolution of the appeal was pending.

Labor matters:

In recent years the Company has experienced a number of strikes or other labor disruptions that have had an adverse impact on its operations and operating results.

The San Martin and Taxco mines in Mexico have been on strike since July 2007. On December 10, 2009, a federal court confirmed the legality of the San Martin strike. In order to recover the control of the San Martin mine and resume operations, on January 27, 2011, the Company filed a court petition requesting that the court establish the Company’s responsibility for the strike and that it define the termination payment for each unionized worker. The court denied the petition alleging that according to Federal labor law, the union was the legitimate party to file the petition. On appeal by the Company, on May 13, 2011, the Mexican federal tribunal accepted the petition of the Company. In July 2011, the union appealed the favorable court decision before the Supreme Court. At June 30, 2012, resolution of the appeal was pending.

In the case of the Taxco mine, following the workers refusal to allow exploration of new reserves, the Company commenced litigation seeking to terminate the labor relationship with workers of the Taxco mine (including the related collective bargaining agreement). On September 1, 2010, the federal labor court issued a ruling approving the termination of the collective bargaining agreement and all the individual labor contracts of the workers affiliated with the Mexican mining union at the Taxco mine. The

ruling was based upon the resistance of the mining union to allow the Company to search for reserves at the Taxco mine. If sustained, this ruling will also have the effect of terminating the protracted strike at the Taxco unit. The mining union appealed the labor court ruling before a federal court. In September 2011, the federal court accepted the union’s appeal and requested that the federal labor court review the procedure and to take into account all the evidence to issue a new resolution. On January 3, 2012, the federal labor court again issued a new resolution, approving the termination of the collective bargaining agreement and all the individual labor contracts of the workers affiliated with the Mexican mining union at the Taxco mine. On January 25, 2012, the mining union appealed the resolution before the federal court. On June 14, 2012, the federal court accepted the union’s appeal and requested the federal labor court to issue a new resolution, taking into account all evidence submitted by the parties.

Other legal matters:

Class actions:

Lemon Bay, LLP v. Americas Mining Corporation (“AMC”), et al.:

Three purported class action derivative lawsuits were filed in the Delaware Court of Chancery (New Castle County) late in December 2004 and early January 2005 relating to the proposed merger transaction between the Company and Minera Mexico, S.A. de C.V. (the “Transaction”), which was completed effective April 1, 2005. On January 31, 2005, the three actions - Lemon Bay, LLP v. AMC, et al., Civil Action No. 961-N, Therault Trust v. Luis Palomino Bonilla, et al., and Southern Peru Copper Corporation et al., Civil Action No. 969-N, and James Sousa v. Southern Peru Copper Corporation, et al., Civil Action No. 978-N — were consolidated into one action, captioned, In re Southern Peru Copper Corporation Shareholder Derivative Litigation, Consol. Civil Action No. 961-N; the complaint filed by Lemon Bay was designated as the operative complaint in the consolidated lawsuit. The consolidated action purports to be brought on behalf of the Company and its common stockholders; the defendants in the consolidated action are AMC, German Larrea Mota-Velasco, Genaro Larrea Mota-Velasco, Oscar Gonzalez Rocha, Emilio Carrillo Gamboa, Jaime Fernando Collazo Gonzalez, Xavier Garcia de Quevedo Topete, Armando Ortega Gomez and Juan Rebolledo Gout (together, the “AMC Defendants”), Carlos Ruiz Sacristan, Harold S. Handelsman, Gilberto Perezalonso Cifuentes, and Luis Miguel Palomino Bonilla (together, the “Special Committee Defendants”).

The consolidated complaint alleges, among other things, that the Transaction was the result of breaches of fiduciary duties by the Company’s directors and was not entirely fair to the Company and its minority stockholders. On December 21, 2010, the Court dismissed the Special Committee Defendants from the action.

On October 14, 2011, the Court issued an opinion on this action finding that SCC had paid AMC too much stock consideration in the Transaction. The Court issued a revised final order and judgment on December 29, 2011. The Court decided that the AMC Defendants were jointly and severally liable for damages in the amount of $1,347 million plus $684.6 million of pre-judgment interest. Post-judgment interest continues to accrue from October 15, 2011. The Court decided that the award is payable by AMC with cash, or with the return of a number of shares of SCC equal in value to award, or by SCC cancelling an equivalent number of shares owned by AMC, or by any combination thereof, so long as the total is equivalent to the amount of the judgment plus accrued post-judgment interest. The Court also awarded attorneys’ fees and expenses in the amount of $304.7 million, or 15% of the judgment, plus post-judgment interest, payable by SCC out of the award and not from existing SCC’s cash.

On January 20, 2012, the AMC defendants appealed the Court’s decisions. On the same date, SCC appealed the Court’s decision related to the award of attorneys’ fees and expenses. On May 3, 2012, the Court accepted the security provided by AMC and granted a stay of the judgment pending final resolution of the appeal.

Oklahoma Firefighters Pension & Retirement System et al. v. SCC:

Four purported class action derivative lawsuits filed in the Delaware Court of Chancery (Oklahoma Firefighters Pension & Retirement System et al. v. SCC et al., Gary Martin et al. v. SCC et al., Thomas Griffin et al. v. SCC et al., and Sheet Metal Workers Pension Plan of Northern California et al. v. SCC et al.) from August 2010 to October 2010 relating to the proposed combination of the Company with AMC, the parent company of Asarco, have been dismissed in light of AMC’s October 28, 2011 announcement that it had withdrawn the proposed transaction to combine the Company with AMC.

The Company is involved in various other legal proceedings incidental to its operations, but the Company does not believe that decisions adverse to it in any such proceedings, individually or in the aggregate, would have a material effect on its financial position or results of operations. Additionally, the Company does not believe that the outcome of the purported class action derivative lawsuits would have a material adverse effect on its financial position or results of operations. While the defendants, including Grupo Mexico and its affiliates, believe that the claims in the purported class action derivative lawsuits are without merit,

the Company cannot assure you that these or future claims, if successful, will not have an adverse effect on Grupo Mexico, AMC or the Company.

Other Contingencies:

Tia Maria:

Tia Maria, an over $1.0 billion Peruvian investment project, was suspended by governmental action in April 2011 in light of protests and disruptions carried out by a small group of activists who alleged, among other things, that the project would result in severe environmental contamination and the diversion of agricultural water resources.

The Company has decided to prepare a new environmental impact assessment (“EIA”) study that we believe will take into account local community concerns, new government guidance and observations from the United Nations Organism hired by MINEM for this purpose. The Company considers that this new EIA process will alleviate all the concerns previously raised by the Tia Maria project’s neighboring communities, provide them with an independent source of information and reaffirm the validity of the Company’s assessment of the project. The Company is confident that this initiative will have a positive effect on its stakeholders and will allow the Company to obtain the approval for the development of the 120,000 ton annual production copper project. As a consequence, and contingent upon receiving all required governmental approvals in the time frame provided for in the law, the mining operations for the project have been rescheduled to start-up in 2015. No assurances can be given as to the specific timing of each such approval.

The Company has legal and valid title to the Tia Maria mining concessions and the over-lapping surface land in the area. None of above noted activities have in any way challenged, revoked, impaired or annulled the Company´s legal rights to the Tia Maria mining concessions and/or the over-lapping surface land titles acquired in the past. All the Company’s property rights on these areas are in full force.

In view of the suspension of this project, the Company has reviewed the carrying value of this asset to ascertain whether impairment exists. Total spending on the project, through June 30, 2012, is $485.8 million. As the project is currently on hold, some of the equipment has been transferred to other Company operations in Mexico and Peru. Should the Tia Maria project not be restarted, the Company is confident that most of the project equipment will continue to be used productively, through reassignment to other mine locations operated by the Company. At June 30, 2012, equipment transferred to other Company operations totaled $175.8 million. The Company believes that an impairment loss, if any, will not be material.

Other commitments:

Power purchase agreement

In 1997, SCC sold its Ilo power plant to an independent power company, Enersur S.A. (“Enersur”). In connection with the sale, a power purchase agreement (“PPA”) was also completed under which SCC agreed to purchase all of its power needs for its current Peruvian operations from Enersur for twenty years, commencing in 1997.

The Company signed in 2009 a Memorandum of Understanding (“MOU”) with Enersur regarding its PPA. The MOU contains new economic terms that the Company believes better reflects current economic conditions of the power industry in Peru. The new economic conditions agreed to in the MOU have been applied by Enersur to its invoices to the Company since May 2009. Additionally, the MOU includes an option for providing power for the Tia Maria project. However, due to the delay at the Tia Maria project the final agreement was put on hold, see caption “Tia Maria” above.

Tax contingency matters:

Tax contingencies are provided for under ASC 740-10-50-15 Uncertain tax position (see Note 4, “Income taxes”).

NOTE 11 — SEGMENT AND RELATED INFORMATION:

Company management views Southern Copper as having three reportable segments and manages on the basis of these segments. The reportable segments identified by the Company are: the Peruvian operations, the Mexican open-pit operations and the Mexican underground mining operations segment identified as the IMMSA unit.

The three reportable segments identified are groups of mines, each of which constitute an operating segment, with similar economic characteristics, type of products, processes and support facilities, similar regulatory environments, similar employee

bargaining contracts and similar currency risks. In addition, each mine within the individual group earns revenues from similar type of customers for their products and services and each group incurs expenses independently, including commercial transactions between groups.

Financial information is regularly prepared for each of the three segments and the results of the Company’s operations are regularly reported to the Chief Operating Officer on the segment basis. The Chief Operating Officer of the Company focuses on operating income and on total assets as measures of performance to evaluate different segments and to make decisions to allocate resources to the reported segments. These are common measures in the mining industry.

Financial information relating to Southern Copper’s segments is as follows:

Employee Stock Purchase Plan:

In January 2007, the Company offered to eligible employees a stock purchase plan (the “Employee Stock Purchase Plan”) through a trust that acquires shares of Grupo Mexico stock for sale to its employees, employees of subsidiaries, and certain affiliated companies. The purchase price is established at the approximate fair market value on the grant date. Every two years employees will be able to acquire title to 50% of the shares paid for the previous two years. The employees will pay for shares purchased through monthly payroll deductions over the eight year period of the plan. At the end of the eight year period, the Company will grant the participant a bonus of 1 share for every 10 shares purchased by the employee.

If Grupo Mexico pays dividends on shares during the eight year period, the participants will be entitled to receive the dividend in cash for all shares that have been fully purchased and paid as of the date that the dividend is paid. If the participant has only partially paid for shares, the entitled dividends will be used to reduce the remaining liability owed for purchased shares.

In the case of voluntary resignation of the employee, the Company will pay to the employee the fair market sales price at the date of resignation of the fully paid shares, net of costs and taxes. When the fair market sales value of the shares is higher than the purchase price, the Company will apply a deduction over the amount to be paid to the employee based on the following schedule:

If the resignation occurs during: |  | % Deducted |
1st year after the grant date |  | 90 | %
2nd year after the grant date |  | 80 | %
3rd year after the grant date |  | 70 | %
4th year after the grant date |  | 60 | %
5th year after the grant date |  | 50 | %
6th year after the grant date |  | 40 | %
7th year after the grant date |  | 20 | %

In the case of involuntary termination of the employee, the Company will pay to the employee the fair market sales price at the date of termination of employment of the fully paid shares, net of costs and taxes. When the fair market value of the shares is higher than the purchase price, the Company will apply a deduction over the amount to be paid to the employee based on the following schedule:

NOTE 14 — FINANCIAL INSTRUMENTS:

Subtopic 810-10 of ASC “Fair value measurement and disclosures — Overall” establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under Subtopic 810-10 are described below:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 - Inputs that are observable, either directly or indirectly, but do not qualify as Level 1 inputs (i.e., quoted prices for similar assets or liabilities).

Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable (other than accounts receivable associated with provisionally priced sales) and accounts payable approximate fair value due to their short maturities. Consequently, such financial instruments are not included in the following table that provides information about the carrying amounts and estimated fair values of other financial instruments that are not measured at fair value in the condensed consolidated balance sheet as of June 30, 2012 and December 31, 2011 (in millions):

|  | As of June 30, 2012 |  | As of December 31, 2011 |

Liabilities: |  |  |  |  |  |  |  |  |
Long-term debt |  | $ | 2,741.0 |  | $ | 3,091.2 |  | $ | 2,745.7 |  | $ | 2,974.9 |

Table of Contents

Long-term debt is carried at amortized cost and its estimated fair value is based on quoted market prices classified as Level 1 in the fair value hierarchy. The Mitsui loan is based on the present value of the cash flow discounted at 10%, which is the Company’s weighted average cost of capital.

Fair values of assets and liabilities measured at fair value on a recurring basis were calculated as follows as of June 30, 2012 and December 31, 2011:

The Company’s short-term trading securities investments are classified as Level 1 because they are valued using quoted prices of the same securities. The Company’s short-term available-for-sale investments are classified as Level 2 because they are valued using quoted prices for similar investments.

Derivatives are valued using financial models that use as their basis readily observable market inputs, such as time value, forward interest rates, volatility factors, and current and forward market prices for foreign exchange rates and a set of probabilities. The Company generally classifies these instruments within Level 2 of the valuation hierarchy. Such derivatives at December 31, 2011, include zero cost collars.

The Company’s accounts receivables associated with provisionally priced copper sales are valued using quoted market prices based on the forward price on the LME or on the COMEX. Such value is classified within Level 1 of the fair value hierarchy. Molybdenum prices are established by reference to the publication Platt’s Metals Week and are considered Level 1 in the fair value hierarchy.

The table below sets forth a summary of changes in the fair value of the Company’s Level 3 short-term investments (corporate bond, asset backed obligations, and mortgage backed securities) for the first six months of 2011.

Part I

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion provides information that management believes is relevant to an assessment and understanding of the consolidated financial condition and results of operations of Southern Copper Corporation and its subsidiaries (collectively, “SCC” the “Company” “our” and “we”). This item should be read in conjunction with our interim unaudited Condensed Consolidated Financial Statements and the notes thereto included in this quarterly report. Additionally, the following discussion and analysis should be read in conjunction with the Management Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements included in Part II of our annual report on Form 10-K for the year ended December 31, 2011.

EXECUTIVE OVERVIEW

Business: Our business is primarily the production and sale of copper. In the process of producing copper, a number of valuable metallurgical by-products are recovered, which we also produce and sell. Market forces outside of our control largely determine the sale prices for our products. Our management, therefore, focuses on value creation through copper production, cost control, production enhancement and maintaining a prudent capital structure to remain profitable. We endeavor to achieve these goals through capital spending programs, exploration efforts and cost reduction programs. Our aim is to remain profitable during periods of low copper prices and to maximize financial performance in periods of high copper prices.

We are one of the world’s largest copper mining companies in terms of production and sales with our principal operations in Peru and Mexico. We also have an active ongoing exploration program in Chile and in 2011 we have started exploration activities in Argentina and Ecuador. In addition to copper we produce significant amounts of other metals, either as a by-product of the copper process or in a number of dedicated mining facilities in Mexico.

Outlook: Various key factors will affect our outcome. These include, but are not limited to, some of the following:

· Changes in copper and molybdenum prices. The average LME copper price was $3.67 per pound in the first half of 2012 14% lower than in the first half of 2011. Average molybdenum, silver and zinc prices in the first half of 2012 also decreased 18%, 11% and 14%, respectively, over average prices in the first half of 2011.

· Sales structure. In the first half of 2012 approximately 77% of our revenue came from the sale of copper, 7% from molybdenum, 7% from silver and 9% from various other products, including zinc, gold and other materials.

· Metals market. During the first half of 2012 metal markets continued to be driven by negative macroeconomic events that affected consumer expectations, the most important ones being Europe’s debt crisis, particularly the problems in Spain and Italy and the possibility of a slowdown of the Chinese economy. Even though we believe copper fundamentals are sound for 2012, demand has been repeatedly negatively influenced by the macro outlook for Europe and China.

At present we perceive a difference in the situations of the Asian markets and the developed markets. In China, several sources point to a growth in demand of approximately 7 to 8% for this year, which should give support to the copper market in the next few months. In the United States and Europe, although demand is weak, inventories are extremely tight and we see them increasing to more normal levels over the next 12 months, particularly in the United States.

Demand from emerging economies is also growing, somewhat offsetting the weaker consumption in the European and United States markets. Some analyst currently estimate that there will be a total refined copper demand growth of 3.5% for 2012. If we consider global copper demand of about 19.3 million tons, this would represent approximately 675,000 tons of additional refined copper demand. On the supply side, production has underperformed badly in 2011, due to labor unrest, power shortages, weather conditions and ore grade declines. We see these events continuing in 2012, constraining supply and maintaining tightness in the copper market.

Regarding molybdenum, our main by-product, even though we saw a 4% molybdenum demand growth in 2011, analysts estimate that the market still shows a 2.6% surplus supply of this metal. We expect that in 2012 the balance between supply and demand will decrease the current market surplus, thereby improving market prices in the near future. Molybdenum is mainly used for the production

of special alloys of stainless steel that require significant hardness, corrosion and heat resistance. Another relatively new usage of this metal is in lubricants and sulfur filtering of heavy oils.

Regarding silver and zinc, we believe that silver prices will have strong support in the coming months due to its industrial uses as well as being perceived as a value shelter in times of economic uncertainty. In addition, we believe that zinc has very good long term fundamentals due to its significant industrial consumption; however, inventories are currently at a relatively high level which tends to maintain a relatively stable zinc price.

· Production. We maintain our 2012 production guidance of 640,000 tons of copper, which includes 3% of copper purchased from third parties. We expect molybdenum production in 2012 to be about 17,200 tons, while zinc and silver production should be around the same level as 2011.

· Capital Expenditures. In the first half of 2012, we spent $407.7 million on capital expenditures and we will continue with our capital investment projects at the Buenavista mine, as well as at the Toquepala and Cuajone expansions. In addition, in the first half of 2012 we spent $21.3 million on our exploration programs.

Tantahuatay mine: This mine, in which we hold a 44.2% interest, is located in Cajamarca, in northern Peru. Production started in August 2011 and in the first six months of 2012 the mine produced 66,700 ounces of gold and 418,600 ounces of silver. In the first six months of 2012, we have recognized $24.7 million in earnings (see “Equity earnings of affiliate”, in our Statement of Earnings) for our share of the net income of the mine.

Peruvian Labor matters: Approximately 60% of the 4,328 Company’s Peruvian workers were unionized at June 30, 2012, represented by eight separate unions. Three of these unions, one at each major production area, represent the majority of the Company’s workers. Collective bargaining agreements with these unions will expire during 2012. The Company has started negotiations with some of these unions and expects that they will likely continue throughout the first quarter of 2013.

KEY MATTERS:

We discuss below several matters that we believe are important to understand our results of operations and financial condition. These matters include (i) our earnings, (ii) our production, (iii) our “operating cash costs” as a measure of our performance, (iv) metal prices, (v) business segments, (vi) the effect of inflation and other local currency issues, and (vii) our capital investment and exploration program.

Net Income: Net income attributable to SCC in the first six months of 2012 was $1,185.0 million an increase of 4.3%, compared with the first six months of 2011. Net income represents 34% of total revenues. This increase was principally a result of an increase in our copper sales volume from increased production at our open pit mines, which offset the effect of the lower prices and resulted in an increase in sales revenues of 1.8%.

We continued showing our strong operating and financial position, which is reflected in an increase of 16% in copper production in the first six months of 2012, as well as increases in our main by-product production, molybdenum (+6%), silver (+14%) and zinc (+8%).

Additionally, we continue our focus on value creation and investing in our organic growth through expansion projects in Mexico and Peru, especially at the Buenavista mine in Mexico. We have spent $407.7 million in the first six months of 2012 on our capital projects and have committed approximately $300 million for mine equipment to support the Buenavista projects.

Production: Second quarter 2012 mined copper production was 10% higher than the second quarter of 2011. Molybdenum, silver and mined zinc in the second quarter of 2012 also increased 4%, 10% and 4% respectively, compared to the second quarter of 2011.

The tables below highlights key mine production data for our Company for the three and six months ended June 30, 2012 and 2011:

|  | Three months ended June 30, |  | Six months ended June 30, |
|  |  |  |  |  | Variance |  |  |  |  |  | Variance |
|  | 2012 |  | 2011 |  | Volume |  | % |  | 2012 |  | 2011 |  | Volume |  | % |

Copper mined production in the second quarter of 2012 increased 9.8% as a result of higher production at our Cuajone, La Caridad and Buenavista mines, which increased their production by 30.6%, 13.3% and 5.3%, respectively, due to higher ore grades and recoveries.

Molybdenum production increased 4.1% in the second quarter of 2012 due to higher production at the Cuajone and La Caridad mines as a result of higher grade and recovery.

Silver mine production increased 9.9% in the second quarter of 2012, principally as a result of higher production at our Cuajone, Buenavista and La Caridad mines which increased production by 31%, 28% and 12.1%, respectively .

Zinc production increased 4% in the second quarter of 2012, mainly as a result of higher grades and recoveries, and production recovery at the Santa Eulalia mine after the flooding problems of prior years were resolved.

Operating Cash Costs: An overall benchmark used by us and a common industry metric to measure performance is operating cash costs per pound of copper produced. Operating cash cost is a non-GAAP measure that does not have a standardized meaning and may not be comparable to similarly titled measures provided by other companies. A reconciliation of our operating cash cost per pound to the cost of sales (exclusive of depreciation, amortization and depletion) as presented in the condensed consolidated statement of earnings is presented under the subheading “Non-GAAP Information Reconciliation” on page 39.

We have defined operating cash cost per pound as cost of sales (exclusive of depreciation, amortization and depletion), less the cost of purchased concentrates, plus selling, general and administrative charges, treatment and refining charges, net revenue (loss) on sale of metal purchased from third parties and by-product revenues, and sales premiums; less workers’ participation and other miscellaneous charges, including the Peruvian royalty charge, the special mining tax and the change in inventory levels; divided by total pounds of copper produced by our own mines. In our calculation of operating cash cost per pound of copper produced, we credit against our costs the revenues from the sale of by-products: molybdenum, zinc, silver, gold and other minor by-products and the premium over market price that we receive on copper sales. We account for the by-product revenues in this way because we consider our principal business to be the production and sale of copper. We believe that our Company is viewed by the investment community as a copper company, and is valued, in large part, by the investment community’s view of the copper market and our ability to produce copper at a reasonable cost. The variation in recent years in the price of molybdenum, as well as variations in the prices of silver and zinc, have had a significant effect on our traditional calculation of cash cost and its comparability between periods. Accordingly, we present cash costs with and without crediting the by-product revenues against our costs.

In conjunction with the review of our operating cash costs, please also see our annual report on Form 10-K for the year ended December 31, 2011, where in Part II (Item 7, Key matters), we discuss our rationale for calculating operating cash costs.

Our operating cash costs per pound, as defined, are presented in the table below, for the three and six months ended June 30, 2012 and 2011.

Our per pound operating cash cost without by-product revenues for the second quarter of 2012 was 4 cents lower than in the second quarter of 2011. This decrease was mainly due to the dilutive effect of higher production in the period. Production cost increased 8.9% while production increased 11.4%. The operating cash cost without by-product revenues for the six month period 2012 also reflects this dilutive effect and increased only 1 cent, compared with the same period of 2011.

Our per pound cash cost for the second quarter and first six months of 2012 when calculated with by-product revenues was 16 cents and 17 cents, respectively, higher than in the comparable periods of 2011. These increases were primarily due to lower by-product credits as a result of lower market prices of all our main by-products and also the dilutive effect resulting from dividing it by higher copper production volume, both partially offset by the higher production of our three main by-products.

Metal Prices: The profitability of our operations is dependent on, and our financial performance is significantly affected by, the international market prices for the products we produce, especially for copper, molybdenum, zinc and silver. Metal prices historically have been subject to wide fluctuations and are affected by numerous factors beyond our control. These factors, which affect each commodity to varying degrees, include international economic and political conditions, levels of supply and demand, the availability and cost of substitutes, inventory levels maintained by producers and others and, to a lesser degree, inventory carrying costs and currency exchange rates. In addition, the market prices of certain metals have on occasion been subject to rapid short-term changes due to economic concerns and financial investments.

We are subject to market risks arising from the volatility of copper and other metal prices. Assuming that expected metal production and sales are achieved, that tax rates are unchanged, giving no effect to potential hedging programs, metal price sensitivity factors would indicate the following change in estimated 2012 net income attributable to SCC resulting from metal price changes:

|  | Copper |  | Molybdenum |  | Zinc |  | Silver |
Change in metal prices (per pound, except silver — per ounce) |  | $ | 0.01 |  | $ | 1.00 |  | $ | 0.01 |  | $ | 1.00 |
Annual change in net income attributable to SCC (in millions) |  | $ | 7.9 |  | $ | 23.2 |  | $ | 1.2 |  | $ | 9.0 |

Business Segments: We view our Company as having three operating segments and manage on the basis of these segments. These segments are our (1) Peruvian operations, (2) our Mexican open-pit operations and (3) our Mexican underground operations, known as our IMMSA unit. Our Peruvian operations include the Toquepala and Cuajone mine complexes and the smelting and refining plants, industrial railroad and port facilities which service both mines. The Peruvian operations produce copper, with significant by-product production of molybdenum, silver and other material. Our Mexican open-pit operations include La Caridad and Buenavista mine complexes, the smelting and refining plants and support facilities which service both mines. The Mexican open-pit operations produce copper, with significant by-product production of molybdenum, silver and other material. Our IMMSA unit includes five underground mines that produce zinc, lead, copper, silver and gold, a coal mine which produces coal and coke, and several industrial processing facilities for zinc, copper and silver.

Segment information is included in our review of “Results of Operations” and also in Note 11 - “Segment and Related Information” of our condensed consolidated financial statements.

Inflation and Exchange Rate Effect of the Peruvian Nuevo Sol and the Mexican Peso: Our functional currency is the U.S. dollar. Portions of our operating costs are denominated in Peruvian nuevos soles and Mexican pesos. Since our revenues are primarily denominated in U.S. dollars, when inflation/deflation in Peru or Mexico is not offset by a change in the exchange rate of the nuevo sol or the peso to the dollar, our financial position, results of operations and cash flows could be adversely affected to the extent that the inflation/devaluation effects are passed onto us by our suppliers or reflected in our wage adjustments. In addition, the dollar value of our net monetary assets denominated in nuevos soles or pesos can be affected by devaluation of the nuevo sol or the peso, resulting in a remeasurement loss in our financial statements. Recent inflation and devaluation rates are provided in the table below for the three and six month periods ended June 30, 2012 and 2011:

Capital Investment and Exploration Programs: We made capital expenditures of $230.3 million and $407.7 million for the three and six months ended June 30, 2012, compared with $110.7 million and $183.6 million in the comparable periods of 2011, respectively. In general, the capital expenditures and projects described below are intended to increase production and/or decrease costs.

Set forth below are descriptions of some of our current expected capital expenditure programs. We expect to meet the cash requirements for these projects from cash on hand, internally generated funds and from additional external financing, if required. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy or market conditions.

Peruvian Operations:

Toquepala projects: Through June 30, 2012, we have spent $212 million. These expenditures include a new crusher and a conveyor belt system to replace rail hauling and other costs, which will allow for future savings. Subject to obtaining the appropriate permits, the Toquepala expansion is scheduled to start production in the first quarter 2014. This project will increase annual production by 100,000 tons of copper and 3,100 tons of molybdenum.

Cuajone expansion: As of June 30, 2012, the Company has spent $113.0 million on two projects related to this unit’s expansion: the Variable Cut Ore Grade project and the High Pressure Grinding Rolls (“HPGR”) project. Current production is showing the initial benefits of the variable cut project, which we anticipate will be at full capacity by the third quarter of 2013, adding 22,000 tons of copper and 700 tons of molybdenum to Cuajone’s annual production.

Tailings disposal at Quebrada Honda: This project increases the height of the existing Quebrada Honda dam to impound future tailings from the Toquepala and Cuajone mills and will extend the expected life of this tailings facility by 25 years. The project has a total budgeted cost of $66.0 million, with $48.6 million expended through June 30, 2012.

Tia Maria project: We continue to work on a new EIA study that we anticipate will address recent government guidance on these studies and assist us to reach an agreement that is fair and mutually satisfactory to all parties. Please see “Tia Maria” in note 10 Commitments and contingencies — Other contingencies.”

Mexican operations:

Crushing, conveying and spreading system at Buenavista (Quebalix): Overall progress is 98% and this facility is expected to begin operating in September 2012. Through June 30, 2012, we have invested $71 million of the $77 million budgeted. This investment consists of a crushing, conveying and spreading system that improves the SXEW copper production by increasing recovery and reducing the required time to extract copper from mineral.

Molybdenum plant at Buenavista: The construction of a molybdenum plant for the current concentrator is at 48% of progress. This project has a budget of $38 million and is expected to begin operations in the first quarter of 2013. It will produce 2,000 tons of molybdenum contained in concentrate.

SXEW III at the Buenavista mine: The project is moving forward. Plant equipment from Tia Maria will allow us to increase the annual plant capacity from 88,000 tons to 120,000 tons. Basic engineering was modified by the supplier to include the construction of an additional conveyor line. Overall progress of the project at the end of June 2012 is 31%. We anticipate that the new plant with a total budget cost of $444 million should start operations in the first half of 2014.

The Buenavista mining expansion project includes mine equipment acquisitions, a second molybdenum plant and a new concentrator with an estimated annual production capacity of 188,000 tons of copper and 2,600 tons of molybdenum. This project has a total capital budget of $1.4 billion and it is expected to begin operation by the first half of 2015. Regarding mine equipment, through June 30, 2012, we have committed $307 million in purchase orders for the acquisition of 5 shovels, 41 trucks, 5 drills and other mine equipment. Basic engineering for the new concentrator is completed; detailed engineering and equipment acquisition are moving forward as scheduled. The bidding process for the steel structure and earthmoving equipment was conducted. Overall progress of the project at June 30, 2012 is 22%.

Pilares project: On October 27, 2011, the Board of Directors approved the development of the second stage of the Pilares mine, with a budget of $136.3 million. In 2008, we acquired 100% ownership of Pilares, with the intention of operating it as an open pit facility. Current mineralized material is estimated at 43.4 million tons with 0.789% of copper sulfide content and 0.077% copper oxide. We expect to increase copper production by 40,000 tons per year by sending mineral from the Pilares site to our La Caridad concentrator.

Angangueo: Basic and detailed engineering are moving forward as scheduled to develop this underground polymetallic deposit in Michoacan, Mexico. With an estimated investment of $131 million, Angangueo will have a potential annual production of 10,400 tons of copper, 9,700 tons of zinc and 3,900 tons of lead. The project is scheduled to begin production in the first half of 2015.

Potential projects:

El Arco: El Arco is a world class copper deposit in the central part of the Baja California peninsula, with estimated mineralized material of over 1.0 billion tons with an ore grade of 0.51% and 14 grams of gold per ton. This project is expected to produce 190,000 tons of copper and 105,000 ounces of gold annually. We continue to invest in land acquisition required for the project. In 2010, the project feasibility study was completed at a cost of $15.0 million.

Los Chancas: This project, located in the department of Apurimac in southern Peru, is a copper and molybdenum porphyry deposit. As a result of the complementary drilling works and the preliminary design of the pit, estimates show 545 million tons of mineralized material with a copper content of 0.59%, molybdenum content of 0.04% and 0.039 grams of gold per ton. During the first quarter of 2012, we completed the pre-feasibility study and we have initiated the bidding process for the feasibility study.

We have a number of other projects that we may develop in the future. We evaluate new projects on the basis of our long-term corporate objectives, expected return on investment, environmental concerns, required investment and estimated production, among other considerations. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy or market conditions.

The above information is based on estimates only. We cannot make any assurances that we will undertake any of these projects or that the information noted is accurate.

Exploration:

In 2011, we began exploration activities in Ecuador and Argentina. Besides these new efforts, we continue with our exploration activities in Mexico, Peru and Chile.

Catanave: We are in the exploration stage for this gold project located in the highlands of Arica, in northern Chile, close to the Bolivian border. Depending on the results of the 2012 drilling program, we will define the next steps for this project.

ACCOUNTING ESTIMATES

Our discussion and analysis of financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. Preparation of these condensed consolidated financial statements requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Management makes its best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: ore reserves, revenue recognition, estimated mine stripping ratios, leachable material and related amortization, the estimated useful lives of fixed assets, asset retirement obligations, litigation and contingencies, valuation

allowances for deferred tax assets, tax positions, fair value of financial instruments and inventory obsolescence. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Net Sales: Net sales for the second quarter 2012 decreased by $141.6 million, compared with the second quarter of 2011. The 7.9% decrease in sales was principally due to the lower copper prices, as well as lower market prices for all our main by-products, partially offset by higher sales volume resulting from higher production.

Net sales in the first six months of 2012 increased by $62.3 million, compared with the first six months of 2011. The 1.8% increase was the result of higher copper sales volume from increased production at our open pit mines, which offset the effect of lower prices for copper and our principal by-products.

Net sales for the three and six months ended June 30, 2011 also include losses on copper hedges of $8.6 million and $44.3 million, respectively.

Operating Costs and Expenses:

Second quarter : Operating costs and expenses were $784.3 million in the second quarter 2012, compared with $802.8 million in the comparable period of 2011. The decrease of $18.5 million was primarily due to:

· $28.1 million of lower cost of sales (exclusive of depreciation, amortization and depletion), partially offset by

· $4.5 million of higher exploration expense mainly at our Mexican operations and

· $5.5 million of higher depreciation and amortization expenses.

Cost of sales (exclusive of depreciation, amortization and depletion) in the second quarter of 2012 was $667.9 million, compared with $696.0 million in the same period of 2011. The decrease of $28.1 million was primarily due to :

· $21.1 million of lower cost of material purchased from third parties, which was replaced by our own production and

· $11.5 million of currency translation effect.

Six months: Operating costs and expenses were $1,617.3 million in the six months ended June 30, 2012, compared with $1,642.0 million in the comparable period of 2011. The decrease of $24.7 million was primarily due to:

· $43.0 million of lower cost of sales (exclusive of depreciation, amortization and depletion), partially offset by

· $11.8 million of higher depreciation and amortization expenses and

· $6.0 million of higher exploration expenses.

Table of Contents

Cost of sales (exclusive of depreciation, amortization and depletion) in the six months ended June 30, 2012 was $1,389.8 million compared with $1,432.8 million in the same period of 2011. The decrease of $43.0 million was primarily due to the following:

· $276.7 million of lower cost of material purchased from third parties, principally at our Peruvian operations, which was replaced by our own production, partially offset by

· $45.5 million of higher fuel and power cost due to market prices,

· $134.7 million of higher labor, material repair and other production cost, principally due to cost inflation and

· $28.5 million of higher workers’ participation due to higher pre-tax earnings.

Non-operating income and expense were an expense of $22.3 million and $55.6 million in the three and six month periods ended June 30, 2012, respectively, compared to an expense of $36.7 million and $81.2 million in the comparable periods of 2011.

The $14.4 million decrease in the second quarter of 2012 is principally due to:

· $18.2 million of gain in the sale of our shares of Compania Internacional Minera, a mining company in which we had a minority participation.

· $6.3 million of lower other income in the second quarter of 2012 due to a gain on the sale of a non-operating property at our Mexican operations in the second quarter of 2011 and

· $1.8 million of higher capitalized interest due to increased capital expenditures, mainly at our Mexican operations.

The $25.6 million decrease in expense in the first six months of 2012 is due to:

· $18.2 million of gain in the sale of our shares of Compania Internacional Minera, a mining company in which we had a minority participation,

· $4.3 million of lower other income in the first six months of 2012 due to a gain on the sale of a non-operating property at our Mexican operations in the first six months of 2011,

· $5.5 million of gain in the fair value of short-term investments and

· $3.8 million of higher capitalized interest due to increased capital expenditures mainly at our Mexican operations.

Income taxes: The income tax provision for the first six months of 2012 and 2011 was $628.7 million and $540.0 million, respectively. These provisions include income taxes for Peru, Mexico and the United States. The provision for income taxes was based on our effective tax rate of 35.1% for the first six months of 2012 as compared to 32.1% in the first six months of 2011. The increase in the effective tax rate for the first six months of 2012 from the tax rate in the 2011 period is principally caused by the new special mining tax in Peru and by the increase in dividends remitted from Mexico in 2012, which required a supplemental provision for U.S. income tax.

Second quarter:

Net sales decreased by $11.7 million to $131.8 million in the second quarter of 2012 from $143.5 million in the second quarter of 2011. The decrease of 8.2% was primarily due to lower metal prices, partially offset by higher copper, zinc and silver sales volume.

Operating costs and expenses in the second quarter of 2012 decreased by $4.0 million to $86.4 million from $90.4 million in the comparable 2011 period. This decrease was primarily due to $6.2 million of lower cost of sales (exclusive of depreciation, amortization and depletion), net of $1.9 million of higher exploration cost at the Charcas and other IMMSA properties.

Six months:

Net sales in the first six months of 2012 were $270.1 million, compared to $286.0 million in the same period of 2011. This decrease of $15.9 million in net sales was primarily due to lower metal prices, partially offset by higher copper and silver sales volume.

Operating costs and expenses in the first six months of 2012 increased by $6.5 million to $178.1 million from $171.6 million in the comparable 2011 period. This increase was primarily due to $4.3 million of higher exploration expenses and $1.8 million of higher cost of sales (exclusive of depreciation, amortization and depletion).

Cost of sales (exclusive of depreciation, amortization and depletion) increased by $1.8 million to $145.4 million in the first six months of 2012 from $143.6 million in the first six months of 2011. The increase was principally related to higher production cost due to higher explosives and repair materials.

Six months ended June 30, 2012:

In the first six months of 2012 net income was $1,188.9 million. Significant items (deducted from), or added, to arrive to operating cash flow included, depreciation, amortization and depletion of $155.4 million and $19.3 million for a deferred tax provision, which increased operating cash flow and $16.9 million of equity participation of affiliate, net of dividends received and $18.2 million of gain on sale of investment, which decreased operating cash flow.

In addition, in the first six months of 2012 an increase in working capital decreased operating cash flow by $223.2 million. The decrease in accounts receivable value was principally due to lower sales prices. The increase in inventory was primarily due to $59.2 million of increase long-term leachable material inventory, mainly at our Buenavista mine, and an increase of $21.9 million of supplies inventory, also mainly at our Mexican operations, partially offset by a decrease of $48.1 million in copper inventory, mainly copper in process, due to the process and sale of copper from third parties at our Peruvian operations. The decrease in accounts payable and accrued liabilities was primarily due to the income tax and workers’ participation payments.

Six months ended June 30, 2011:

In the first six months of 2011 net income was $1,140.3 million. Significant items (deducted from), or added, to arrive to operating cash flow included depreciation, amortization and depletion of $143.5 million, which increased operating cash flow and $16.5 million of deferred income tax benefit, which decreased operating cash flow.

In addition, in the first six months of 2011 an increase in working capital decreased operating cash flow by $548.8 million. The increase in accounts receivable value was principally due to higher sales in the period as a result of added production from Buenavista and higher metal prices. The increase in inventory was primarily due to the increase in copper in process at our Mexican operations due to the restoration of production at the Buenavista mine and a temporary increase in anodes in process at the Ilo smelter at our Peruvian operations. The decrease in accounts payable and accrued liabilities was primarily due to the income tax and workers’ participation payments.

IMPACT OF NEW ACCOUNTING STANDARDS

During the first six months of 2012, there were no new accounting standard updates which impacted our financial statements.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

Metal price sensitivity:

We are subject to market risks arising from the volatility of copper and other metal prices. Assuming that expected metal production and sales are achieved, that tax rates are unchanged, and giving no effects to potential hedging programs, metal price sensitivity factors would indicate the following change in estimated 2012 net income attributable to SCC resulting from metal price changes:

|  | Copper |  | Molybdenum |  | Zinc |  | Silver |
Change in metal prices (per pound except silver — per ounce) |  | $ | 0.01 |  | $ | 1.00 |  | $ | 0.01 |  | $ | 1.00 |
Annual change in net income attributable to SCC (in millions) |  | $ | 7.9 |  | $ | 23.2 |  | $ | 1.2 |  | $ | 9.0 |

Foreign currency exchange risk:

Our functional currency is the U.S. dollar. Portions of our operating costs are denominated in Peruvian nuevos soles and Mexican pesos. Since our revenues are primarily denominated in U.S. dollars, when inflation/deflation in Peru or Mexico is not offset by a change in the exchange rate of the nuevo sol or the peso, respectively, to the dollar, our financial position, results of operations and cash flows could be adversely affected to the extent that the inflation/devaluation effects are passed on to us by our suppliers or reflected in our wage adjustments. In addition, the dollar value of our net monetary assets denominated in nuevos soles or pesos can be affected by devaluation of the nuevo sol or the peso, resulting in a remeasurement loss in our financial statements. Recent inflation and devaluation rates are provided in the table below for the three and six month periods ended June 30, 2012 and 2011:

|  | Three Months Ended June 30, |  | Six Months Ended June 30, |
|  | 2012 |  | 2011 |  | 2012 |  | 2011 |
Peru: |  |  |  |  |  |  |  |  |
Peruvian inflation rate |  | 0.5 | % | 0.8 | % | 1.5 | % | 2.3 | %
Nuevo sol/dollar devaluation/(appreciation) rate |  | 0.1 | % | (2.0 | )% | (1.0 | )% | (2.1 | )%
Mexico: |  |  |  |  |  |  |  |  |
Mexican inflation rate |  | (0.2 | )% | (0.8 | )% | 0.8 | % | 0.3 | %
Peso / dollar devaluation/(appreciation) rate |  | 6.3 | % | (1.1 | )% | (2.3 | )% | (4.2 | )%

Change in monetary position:

Assuming an exchange rate variance of 10% at June 30, 2012 we estimate our net monetary position in Peruvian nuevo sol and Mexican peso would increase (decrease) our net earnings as follows:

Variance |  | Effect in net earnings |
|  | ($ in millions) |
Appreciation of 10% in exchange rate of U.S. dollar vs. nuevo sol |  | $ | 9.9 |
Devaluation of 10% in exchange rate of U.S. dollar vs. nuevo sol |  | (8.1 | )
Appreciation of 10% in exchange rate of U.S. dollar vs. Mexican peso |  | 2.0 |
Devaluation of 10% in exchange rate of U.S. dollar vs. Mexican peso |  | $ | (2.4 | )

Interest rate risk:

A portion of our outstanding debt bears interest at variable rates and accordingly is sensitive to changes in interest rates. Interest rate changes would also result in gains or losses in the market value of our fixed rate debt portfolio due to differences in market interest rates and the rates at the inception of the debt agreements. There have been no material changes in our interest rate risk at June 30, 2012. As most of our debt is at fixed rates, a change in market interest rates of 1% would not have a material impact on our cash flows.

Provisionally priced sales:

At June 30, 2012, we have recorded provisionally priced sales of 47.8 million pounds of copper, at an average forward price of $3.491 per pound. Also we have recorded provisionally priced sales of 9.0 million pounds of molybdenum at the June 30, 2012

market price of $13.13 per pound. These sales are subject to final pricing based on the average monthly LME or COMEX copper prices and Dealer Oxide molybdenum prices in the future month of settlement. See Note 5 to our condensed consolidated financial statements.

As part of our risk management policy, we occasionally use derivative instruments to (i) safeguard the corporate assets, (ii) insure the value of our future revenue stream and (iii) lessen the impact of unforeseen market swings of our sales revenues. To comply with these objectives we, from time to time, enter into commodity price derivatives, interest rate derivatives, exchange rate derivatives and other instruments. We do not enter into derivative contracts unless we anticipate a future activity that is likely to occur that will result in exposing us to market risk.

Copper Hedges:

During the second quarter of 2012 and as of June 30, 2012 we did not hold copper derivative contracts.

Item 4. Controls and Procedures

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of June 30, 2012, the Company conducted an evaluation under the supervision and with the participation of the Company’s Disclosure Committee and the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness and the design and operation of the Company’s disclosure controls and procedures. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective as of June 30, 2012, to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is:

1. recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and

2. accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

CHANGES IN INTERNAL CONTROLS OVER FINANCIAL REPORTING

There was no change in the Company’s internal controls over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) that occurred during the quarter ended June 30, 2012 that has materially affected, or is reasonably likely to materially affect, the Company’s internal controls over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Southern Copper Corporation:

We have reviewed the accompanying condensed consolidated balance sheet of Southern Copper Corporation and subsidiaries (the “Company”) as of June 30, 2012, and the related condensed consolidated statements of earnings, comprehensive income and cash flows for the three-month and six-month periods ended June 30, 2012 and 2011. These interim financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Southern Copper Corporation and subsidiaries as of December 31, 2011, and the related consolidated statements of earnings, comprehensive income, equity, and cash flows for the year then ended (not presented herein); and in our report dated February 27, 2012, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2011 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
