NOTE 1 — DESCRIPTION OF THE BUSINESS:

The Company is a majority-owned, indirect subsidiary of Grupo Mexico S.A.B. de C.V. (“Grupo Mexico”). At March 31, 2017, Grupo Mexico through its wholly-owned subsidiary Americas Mining Corporation (“AMC”) owned 88.9% of the Company’s capital stock. The condensed consolidated financial statements presented herein consist of the accounts of Southern Copper Corporation (“SCC” or the “Company”), a Delaware corporation, and its subsidiaries. The Company is an integrated producer of copper and other minerals, and operates mining, smelting and refining facilities in Peru and Mexico. The Company conducts its primary operations in Peru through a registered branch (the “Peruvian Branch” or “Branch” or “SPCC Peru Branch”). The Peruvian Branch is not a corporation separate from the Company. The Company’s Mexican operations are conducted through subsidiaries. The Company also conducts exploration activities in Argentina, Chile, Ecuador, Mexico and Peru.

In the opinion of the Company, 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 March 31, 2017 and the results of operations, comprehensive income and cash flows for the three months ended March 31, 2017 and 2016. The results of operations for the three months ended March 31, 2017 are not necessarily indicative of the results to be expected for the full year. The December 31, 2016 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 (“GAAP”). The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements at December 31, 2016 and notes included in the Company’s 2016 annual report on Form 10-K.

In the first quarter 2017 and 2016, total leaching costs capitalized as non-current inventory of ore stockpiles on leach pads amounted to $120.8 million and $124.8 million, respectively. Leaching inventories recognized in cost of sales amounted to $82.1 million and $79.2 million for the first quarter 2017 and 2016, respectively.

NOTE 4 — INCOME TAXES:

The income tax provision and the effective income tax rate for the first quarter 2017 and 2016 consisted of ($ in millions):

	2017			2016
Statutory income tax provision	$	148.5		$	82.6
Peruvian royalty	0.4			—
Mexican royalty	21.4			9.3
Peruvian special mining tax	5.9			0.4
Income tax provision	$	176.2		$	92.3

Effective income tax rate	36.3		%	33.8		%

These provisions include income taxes for Peru, Mexico and the United States. In addition, a Mexican royalty tax, a portion of the Peruvian royalty tax and the Peruvian special mining tax are included in the income tax provision. The increase in the effective tax rate for the first quarter of 2017 from the same period in the prior year is primarily due to an increase of forecasted dividends from Minera Mexico.

Table of Contents

Peruvian income tax rate: In December 2016, the Peruvian Government enacted income tax law changes to both the income tax and dividend tax rate that became effective on January 1, 2017. The 2016 rates and the new rates are as follows:

Year	Income Tax Rate		Dividend Tax Rate
2016	28.0	%	6.8	%
2017 and later	29.5	%	5	%

Peruvian royalty and special mining tax: The mining royalty charge is based on operating income margins with graduated rates ranging from 1% to 12% of operating profits, with a minimum royalty charge assessed at 1% of net sales. If the operating income margin is 10% or less, the royalty charge is 1% and for each 5% increment in the operating income margin, the royalty charge rate increases by 0.75%, up to a maximum of 12%. The minimum royalty charge assessed at 1% of net sales is recorded as cost of sales and those amounts assessed against operating income are included in the income tax provision. The Company has accrued $5.5 million and $4.1 million of royalty charge in the first quarter 2017 and 2016, respectively, of which $0.4 million was included in income taxes in 2017; no amounts were included in income tax in the first quarter 2016.

The special mining tax is based on operating income and its rate ranges from 2% to 8.4%. It begins at 2% for operating income margin up to 10% and increases by 0.4% of operating income for each additional 5% of operating income until 85% of operating income is reached. The Company has accrued $5.9 million and $0.4 million of special mining tax as part of the income tax provision for the first quarter 2017 and 2016, respectively.

Mexican mining royalty: Mexico has a mining royalty charge of 7.5% on earnings before taxes as defined by Mexican tax regulations and an additional royalty charge of 0.5% over gross income from sales of gold, silver and platinum. The Company has accrued $21.4 million and $9.3 million of royalty taxes as part of the income tax provision for the first quarter 2017 and 2016, respectively. In the first quarter of 2017, the Company has paid $54.3 million for year 2016 mining royalty.

Accounting for uncertainty in income taxes: In the first quarter 2017, there were no changes in the Company’s uncertain tax positions.

NOTE 5 — PROVISIONALLY PRICED SALES:

At March 31, 2017, the Company has recorded provisionally priced sales of copper at average forward prices per pound, and molybdenum at the March 31, 2017 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 March 31, 2017:

	Sales volume (million lbs.)	Priced at (per pound)		Month of settlement
Copper	51.0	$	2.65	From April 2017 to May 2017
Molybdenum	10.4	$	8.85	From April 2017 to June 2017

The provisional sales price adjustment included in accounts receivable and net sales at March, 31, 2017 includes positive adjustments of $3.0 million and $10.4 million for copper and molybdenum, respectively.

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 - ASSET RETIREMENT OBLIGATION:

The Company maintains an 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, the Company is required to provide annual guarantees over the estimated life of the mines, based on a present value approach, and to furnish the funds for the asset retirement obligation. This law requires a review of closing plans every five years. Currently and for 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 $30.8 million. Through March 2017, the Company has provided guarantees of $26.9 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 Ilo smelter and refinery, and the shops and auxiliary facilities at the three units.

In 2010, the Company announced to the Mexican federal environmental authorities its closure plans for the copper smelter plant at San Luis Potosi. The Company initiated a program for plant demolition and soil remediation with a budget of $66.2 million, which has been spent through March 31, 2017. Plant demolition and construction of a confinement area at the south of the property were completed in 2012. In accordance with remediation goals previously approved by environmental authorities, soil remediation and on-site encapsulation on a second confinement area of impacted soils have been completed. Confirmation sampling was successfully completed. On September 2, 2016, the environmental authorities approved the conclusion of the remediation effort. The Company continues studying the possibilities for this property in order to decide whether to sell or develop the property. The overall cost recognized for mining closure in Mexico includes the estimated costs of dismantling concentrators, smelter and refinery plants, shops and other facilities. In 2016, we added $9.5 million related to the Quebalix IV closure plan, a project that is part of the Buenavista expansion.

The following table summarizes the asset retirement obligation activity for the three months ended March 31, 2017 and 2016 (in millions):

NOTE 7 — RELATED PARTY TRANSACTIONS:

The Company has entered into certain transactions in the ordinary course of business with parties that are controlling shareholders or their affiliates. These transactions include the lease of office space, air transportation and construction services and products and services related to mining and refining. The Company lends and borrows funds among affiliates for acquisitions and other corporate purposes. These financial transactions bear interest and are subject to review and approval by senior management, as are all related party transactions. It is the Company’s policy that the Audit Committee of the Board of Directors shall review all related party transactions.

Grupo Mexico, the parent and the majority indirect stockholder of the Company, and its affiliates provide various services to the Company. These services are primarily related to accounting, legal, tax, financial, treasury, human resources, price risk assessment and hedging, purchasing, procurement and logistics, sales and administrative and other support services. The Company pays Grupo Mexico for these services and expects to continue requiring these in the future.

The Company’s Mexican operations paid fees for freight services provided by Ferrocarril Mexicano S.A de C.V., for construction services provided by Mexico Proyectos y Desarrollo S.A. de C.V. and its affiliates, and for drilling services provided by Compania Perforadora Mexico S.A.P.I. de C.V. All of these companies are subsidiaries of Grupo Mexico.

The Company’s Mexican operations purchased scrap and other residual copper mineral from Asarco LLC, and power from MGE. Both companies are subsidiaries of Grupo Mexico.

In 2005, the Company organized MGE, as a subsidiary of Minera Mexico, for the construction of two power plants to supply power to the Company’s Mexican operations. In May 2010, the Company’s Mexican operations granted a $350 million line of credit to MGE for the construction of the power plants. That line of credit was due on December 31, 2012 and carried an interest rate of 4.4%. In the first quarter of 2012, Controladora de Infraestructura Energetica Mexico, S. A. de C. V., an indirect subsidiary of Grupo Mexico, acquired 99.999% of MGE through a capital subscription of 1,928.6 million of Mexican pesos (approximately $150 million), reducing Minera Mexico’s participation to less than 0.001%. As consequence of this change in control, MGE became an indirect subsidiary of Grupo Mexico. Additionally, at the same time, MGE paid $150 million to the Company’s Mexican operations partially reducing the total debt. The remaining balance was restructured as subordinated debt of MGE. In the third quarter of 2016, MGE repaid the outstanding balance of the debt. Related to this loan, the Company recorded interest income of $1.6 million in the first quarter of 2016.

In 2012, the Company signed a power purchase agreement with MGE, whereby MGE will supply some of the Company’s Mexican operations with power through 2032. MGE completed construction of its first power plant in June 2013 and the second plant, in the second quarter of 2014. These plants are natural gas-fired combined cycle power generating units, with a net total capacity of 516.2 megawatts. The first plant began supplying power to the Company in December 2013, and the second plant began to supply power in June 2015. MGE is supplying a portion of its power output to third-party energy users.

On August 4, 2014, Mexico Generadora de Energia Eolica S. de R.L. de C.V, an indirect subsidiary of Grupo Mexico, located in Oaxaca, Mexico, acquired Eolica el Retiro. Eolica el Retiro is a windfarm that has 37 wind turbines. This company started operations in January 2014 and started to sell power to IMMSA and other subsidiaries of Grupo Mexico in the third quarter of 2014. Eolica el Retiro is supplying approximately 22% of its power output to IMMSA.

The Company sold copper cathodes, rod and anodes, as well as sulfuric acid, silver, gold and lime to Asarco LLC. In addition, the Company received fees for building rental and maintenance services provided to Mexico Proyectos y Desarrollos, S.A. de C.V. and its affiliates and to Perforadora Mexico S.A.P.I. de C.V., and for natural gas and services provided to MGE; all subsidiaries of Grupo Mexico.

NOTE 9 — 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 others, water recovery systems to conserve water and minimize the 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 investments in the three months ended March 31, 2017 and 2016 were as follows (in millions):

	2017		2016
Peruvian operations	$	16.5	$	10.1
Mexican operations	22.1		29.1
	$	38.6	$	39.2

Peruvian operations: The Company’s operations are subject to applicable Peruvian environmental laws and regulations. The Peruvian government, through the Ministry of Environment (“MINAM”) conducts annual audits of the Company’s Peruvian mining and metallurgical operations. Through these environmental audits, matters related to environmental obligation, compliance with legal requirements, atmospheric emissions, effluent monitoring and waste management 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 assurances for future mine closure and remediation. In accordance with the requirements of this law, the Company’s closure plans were approved by MINEM. See Note 6 “Asset retirement obligation,” for further discussion of this matter. In accordance with the requirements of the law, in 2015 the Company submitted the closure plans for the Tia Maria project and for the Toquepala expansion. The process of review and approval of closure plans usually takes several months. In March 2016, MINEM approved the Mining Closure Plan for the Toquepala expansion project. The closure plan for the Tia Maria project is pending approval.

In 2008, the Peruvian government enacted environmental regulations establishing more stringent air quality standards (“AQS”) for daily sulfur dioxide (“SO2”) in the air for the Peruvian territory. These regulations, as amended in 2013, recognize distinct zones/areas, as atmospheric basins. MINAM has established three atmospheric basins that require further attention to comply with the air quality standards. The Ilo basin is one of these three areas and the Company’s smelter and refinery are part of the area. A supreme decree issued on April 8, 2014, indicates that mining companies should review their compliance with these regulations and develop a modification plan to reach compliance.

In April 2017, MINAM published for comments a proposed Supreme Decree which will define new AQS for daily sulfur dioxide for the Peruvian territory, in order to adopt standards similar to comparable countries and to conform them to the technical capabilities available in Peru, while ensuring the protection of public health. This proposed decree considers criteria established by the World Health Organization for the determination of environmental quality standards, as well as current AQS standards from other countries such as the United States, Canada and Chile. It concludes that it is appropriate to establish a mean 24-hour AQS

Table of Contents

equal to 250 micrograms per cubic meter (µg/m3) of SO2 to replace the current 24-hour AQS of 20 µg/m3 of SO2, effective since 2014.

The Company believes that if approved, these new AQS will be more appropriate for Peru and will allow Peruvian industry to be competitive with other countries. The Company will evaluate the potential impact of these new standards, however, it is expected that its adoption will not have a material impact on the financial position of the Company, as currently the Company maintains a significantly lower daily average level of µg/m3 of SO2 than required by the new AQS.

In 2013, the Peruvian government enacted soil environmental quality standards (“SQS”) applicable to any existing facility or project that generates or could generate the risk of soil contamination in its area of operation or influence. In March 2014, MINAM issued a supreme decree, which establishes additional provisions for the gradual implementation of SQS. Under this rule the Company had twelve months to identify contaminated sites in and around its facilities and present a report of identified contaminated sites. This report was submitted to MINEM in April 2015. After a review of the report, MINEM should evaluate and issue a report to the Company, which will allow it to continue to the next phase. As of March 31, 2017, the Company is awaiting an official response from MINEM. Once notified by MINEM, the Company must prepare a characterization study to determine the depth, extent and physio-chemical composition of the contaminated areas and define an appropriate remediation plan and the time-frame for completion. In addition, the Company must submit for approval a Soil Decontamination Plan (SDP) within 24 months after being notified by the authority. This SDP must include remediation actions, a schedule and compliance deadlines. Also under this rule, if deemed necessary and given reasonable justification, the Company may request a one year extension for the decontamination plan.

Soil confirmation tests must be carried out after completion of decontamination actions (within the approved schedule) and results must be presented to authorities within 30 days after receiving such results. Non-compliance with this obligation or with decontamination goals will carry penalties, although no specific sanctions have been established yet. During compliance with this schedule, companies cannot be penalized for non-compliance with the SQS.

While the Company believes that there is a reasonable possibility that a potential loss contingency may exist, it cannot currently estimate the amount of the contingency. The Company believes that a reasonable determination of the loss will be possible once the characterization study and the SDP are substantially completed. At that time the Company will be in a position to estimate the remediation cost. Further, the Company does not believe that it can estimate a reasonable range of possible costs until the noted studies have substantially progressed and therefore is not be able to disclose a range of costs that is meaningful.

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.

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. It may also initiate administrative proceedings against companies that violate environmental laws, which in the most extreme cases may result in the temporary or permanent shutdown of non-complying facilities, the revocation of operating licenses and/or other sanctions or fines.

In 2011, the General Law was amended, giving 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 as long as it can be argued that the harm may be caused. In addition, in 2011, amendments to the Civil Federal Procedures Code (“CFPC”) were enacted. 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.

In 2013, the Environmental Liability Federal Law was enacted. The law establishes general guidelines for actions to be considered to likely cause environmental harm. If a possible determination regarding harm occurs, environmental clean-up and remedial actions sufficient to restore environment to a pre-existing condition should be taken. Under this law, if restoration is not possible, compensation measures should be provided. Criminal penalties and monetary fines can be imposed under this law.

In 2014, an accidental spill of approximately 40,000 cubic meters of copper sulfate solution occurred at a Buenavista mine leaching pond. This solution reached the Bacanuchi River and the Sonora River. The Company took immediate actions to contain the spill, and to comply with all necessary legal requirements. The Company hired contractors including environmental specialists and assigned more than 1,200 of its own personnel to clean the river. In addition, the Company developed a service program to assist the residents of the Sonora River region.

The National Water Commission, the Federal Commission for the Protection of Sanitary Risk and PROFEPA initiated administrative proceedings regarding the spill to determine possible environmental and health damages. On August 19, 2014, PROFEPA, as part of the administrative proceeding initiated after the spill, announced the filing of a criminal complaint against Buenavista del Cobre S.A. de C.V. (“BVC”), a subsidiary of the Company, in order to determine those responsible for the environmental damages. The Company is vigorously defending itself against this complaint. As of March 31, 2017, the case remains in the procedural stages and is pending resolution.

On September 15, 2014, the Company executed an administrative agreement with PROFEPA, providing for the submission of a remediation action plan to the Mexican Ministry of Environment and Natural Resources (Secretaria de Medio Ambiente y Recursos Naturales “SEMARNAT”). The general remediation program submitted to SEMARNAT was approved on January 6, 2015.

The Company also created a trust with a Mexican development bank, acting as a Trustee to support environmental remedial actions in connection with the spill, to comply with the remedial action plan and to compensate those persons adversely affected by the spill. The Company committed up to two billion Mexican pesos (approximately $150 million). A technical committee for the trust was created with representatives from the federal government, the Company and specialists assisted by a team of environmental experts to ensure the proper use of the funds. Along with the administrative agreement executed with PROFEPA, the trust served as an alternative mechanism for dispute resolution to mitigate public and private litigation risks.

On December 1, 2016, SEMARNAT issued its final resolution which held that all remediation actions contained in the Remediation Plan, as approved by the same authority, had been fully fulfilled, complied with no pending requirements, except for biological monitoring activities at the Sonora River that will be continued until the first semester of 2019 pursuant to such Plan. On January 26, 2017, PROFEPA issued its final resolution under which it declared all mitigation actions completed and its investigation closed. In light of the above, the Company has obtained all necessary formal rulings from SEMARNAT and PROFEPA. On February 7, 2017, the Company closed the trust. In addition, as a result of this process, $10.2 million of excess provision was reversed in the first quarter of 2017. The total expense recorded for this accident in 2014 and 2015 was $136.4 million. Therefore, this matter is closed.

Through the first half of 2015, six collective action lawsuits were filed in federal courts in Mexico City and Sonora against two subsidiaries of the Company seeking economic compensation, clean up and remedial activities in order to restore the environment to its pre-existing conditions. Four of the collective action lawsuits have been dismissed by the court. The plaintiffs in the two remaining lawsuits are: Acciones Colectivas de Sinaloa, A.C. which established two collective actions (one of which was dismissed on September 26, 2016); and Ana Luisa Salazar Medina et al. which has been granted a collective action certification. The plaintiffs have requested cautionary measures on the construction of facilities for the monitoring of public health services and the prohibition of the closure of the Río Sonora Trust.

Similarly, during 2015, eight civil action lawsuits were filed against BVC in the state courts of Sonora seeking damages for alleged injuries and for moral damages as a consequence of the spill. The plaintiffs in the state court lawsuits are: Jose Vicente Arriola Nunez et al; Santana Ruiz Molina et al; Andres Nogales Romero et al; Teodoro Javier Robles et al; Gildardo Vasquez Carvajal et al; Rafael Noriega Souffle et al; Grupo Banamichi Unido de Sonora El Dorado, S.C. de R.L. de C.V; and Marcelino Mercado Cruz. In 2016, three additional civil action lawsuits, claiming the same damages, were filed by Juan Melquicedec Lebaron; Blanca Lidia Valenzuela Rivera et al and Ramona Franco Quijada et al. In 2017, BVC was served with twenty six additional civil action lawsuits, claiming the same damages; those lawsuits were filed by Francisco Javier Molina Peralta et al; Anacleto Cohen Machini et al; Francisco Rafael Alvarez Ruiz et al; Jose Alberto Martinez Bracamonte et al; Gloria del Carmen Ramirez Duarte et al; Flor Margarita Sabori et al; Blanca Esthela Ruiz Toledo et al; Julio Alfonso Corral Domínguez et al; Maria Eduwiges Bracamonte Villa et al; Francisca Marquez Dominguez et al; Jose Juan Romo Bravo et al; Jose Alfredo Garcia Leyva et al; Gloria Irma Dominguez Perez et al; Maria del Refugio Romero et al; Miguel Rivas Medina et al; Yolanda Valenzuela Garrobo et al; Maria Elena Garcia Leyva et al; Manuel Alfonso Ortiz Valenzuela et al; Francisco Alberto Arvayo Romero et al; Maria del Carmen Villanueva Lopez et al; Manuel Martin Garcia Salazar; Miguel Garcia Arguelles et al; Dora Elena Rodriguez Ochoa et al; Honora Eduwiges Ortiz Rodriguez et al; Francisco Jose Martinez Lopez et al; Maria Eduwiges Lopez Bustamente.

Table of Contents

During 2015, four constitutional lawsuits (juicios de amparo) were filed before Federal Courts against various authorities and against a subsidiary of the Company, arguing; (i) the alleged lack of a waste management program approved by SEMARNAT; (ii) the alleged lack of a remediation plan approved by SEMARNAT with regard to the August 2014 spill; (iii) the alleged lack of community approval regarding the environmental impact authorizations granted by SEMARNAT to one subsidiary of the Company; and (iv) the alleged inactivity of the authorities with regard of the spill in August 2014. The plaintiffs of those lawsuits are: Francisca Garcia Enriquez, et al which established two lawsuits, Francisco Ramon Miranda, et al and Jesus David Lopez Peralta et al. During the third quarter of 2016, three additional constitutional lawsuits, claiming same damages were filed by Maria Elena Heredia Bustamante et al; Martin Eligio Ortiz Gamez et al; and Maria de los Angeles Enriquez Bacame et al.

It is not currently possible to determine the extent of the damages sought in these state and federal lawsuits but the Company considers that these lawsuits are without merit. Accordingly, the Company is vigorously defending against them. Nevertheless, the Company considers that none of the legal proceedings resulting from the spill, individually or in the aggregate, would have a material effect on its financial position or results of operations.

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 investments.

Litigation matters:

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, pursuant to a former Peruvian mandated profit sharing law. The labor share litigation is based on claims of former employees for ownership of labor shares that the plaintiffs state that the Branch did not issue during the 1970s until 1979 under such former Peruvian mandated profit sharing law.

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”, 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 “sol”. Due to a past period of high inflation between 1985 and 1990, one billion of old soles is equivalent to today’s one sol.

On September 23, 2015, a lower court that ordered the delivery by the Branch of the labor shares, seized 10,501,857 investment shares owned by SCC and Compania Minera Los Tolmos, S.A. (“Los Tolmos”). The Company is vigorously defending against these measures, and has challenged them on various grounds, mainly because a “labor share” created by law in 1979 is not equivalent to an “investment share”, on a one to one basis, as the latter must recognize the Peruvian inflation since 1980. One “investment share” represents ten million “labor shares”. Additionally, the seized investment shares are owned by SCC and Los Tolmos, companies that are not a party in the lawsuit. In December 2015, the Company appealed the lower court´s decision before the Superior Court that declared without merit its opposition to the seizure.

On October 4, 2016, the Superior Court issued Resolution N°10 which ruled that the seizure of the corporation´s investment shares of Los Tolmos in 2015 was unfounded. To reach this assertion, the Lima Superior Court recognizes that the labor shares have suffered variations in their denomination and face value, due to the currency changes suffered in Peru since 1985 to 1991, for which a first share exchange was made at a rate of 10 to 1, and later at a rate of 1,000 to 1. The Court also indicated that SCC’s assertion that the plaintiffs had participated in each of the labor share exchange transactions has not been proven. Accordingly, the judge in charge of the case must define this situation and determine (a) which plaintiffs received the labor shares to determine who are the holders of the current investment share certificates, (b) who have sold their shares, (c) determine the dividend amounts that

Table of Contents

have been generated by such shares and identify the plaintiffs who have collected the dividends, and (d) review the shares ledger. The judge ordered that an expert be appointed to assist in defining these items.

In addition, Resolution N° 10 also ruled that the value and proportion of the 10,185,700 labor shares represented by the plaintiffs must be mathematically determined in respect to the total of 57,649,479 current investment shares issued by the Branch.

The Company considers that the Superior Court’s decision is important because it recognizes that the value of the original labor shares was affected by the fluctuations in Peruvian currency, which changed over time from the original “sol de oro” to the “inti”, and subsequently to the “Nuevo sol” or currently simply referred to the “sol”. Such fluctuation affected the value of a labor share.

SCC’s Peruvian Branch believes that the review by an expert will establish that the labor shares ordered to be paid by the Court are not equivalent on a one to one ratio to the current investment shares, as well as to prove the Company’s delivery of the labor shares to some of the plaintiffs. The Court did not define the amount to be paid, however, taking into account the effect of currency fluctuation, the Company expects that the final amount of this contingency will not be material.

In addition to the aforementioned lawsuit, 13 additional lawsuits have been filed against SCC’s Branch, 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. SCC’s Peruvian Branch has answered the complaints and denied the validity of the asserted claims. Additionally, in light of the Superior Court’s decision in the Garcia Ataucuri lawsuit the Company believes that any liability established for these lawsuits will not be material to the Company’s financial position.

The “Virgen Maria” Mining Concessions of the Tia Maria Mining Project

The Tia Maria project includes various mining concessions, totaling 32,989.64 hectares. One of the concessions is the “Virgen Maria” mining concession totaling 943.72 hectares or 2.9% of the total mining concessions.

Related to the “Virgen Maria” mining concessions, in August 2009, a lawsuit was filed against SCC’s Branch by the former stockholders of Exploraciones de Concesiones Metalicas S.A.C. (“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 after lengthy negotiations with the plaintiffs, and after the plaintiffs, which were all the stockholders of Excomet, approved the transaction in a general stockholders’ meeting. Excomet was at the time owner of the “Virgen Maria” mining concession. In October 2011, the civil court dismissed the case on the grounds that the claim had been barred by the statute of limitations. On appeal by the plaintiffs, the superior court reversed the lower court’s decision and remanded it to the lower court for further proceedings. In August 2015, the lower court dismissed the case on the grounds that the plaintiffs had not proven the alleged unfairness of the negotiations. The plaintiffs appealed this resolution before the Superior Court. In September 2016, the Superior Court confirmed the lower court’s resolution and the plaintiffs filed an extraordinary appeal in order to have the case reviewed by the Supreme Court. As of March 31, 2017, the case remains pending resolution without further developments.

The Company asserts that this lawsuit is without merit and is vigorously defending against it. Additionally, the amount of this contingency cannot be reasonably estimated by management at this time.

The Tia Maria Mining Project

There are five lawsuits filed against the Peruvian Branch of the Company related to the Tia Maria project. The lawsuits seek (i) to declare null and void the resolution which approved the Environmental Impact Assessment of the project; (ii) the cancellation of the project and the withdrawal of mining activities in the area and (iii) to declare null and void the mining concession application of the Tia Maria project. The lawsuits were filed by Messrs. Jorge Isaac del Carpio Lazo (filed May 22, 2015), Ernesto Mendoza Padilla (filed May 26, 2015), Juan Alberto Guillen Lopez (filed June 18, 2015), Hernan Raul Hatamare Hual (filed August 6, 2015) and Nicolas Belfiore Nicolini (filed November 13, 2015).

The del Carpio Lazio case was rejected by the court of first instance on November 14, 2016. The Plaintiff filed an appeal before the Superior Court on January 3, 2017. As of March 31, 2017, the case remains pending resolution without further developments.

The Mendoza Padilla case was rejected by the lower court on July 8, 2015. This ruling was confirmed by the Superior Court on June 14, 2016. On July 12, 2016, the case was appealed before the Constitutional Court. As of March 31, 2017, the case remains pending resolution without further developments.

Table of Contents

In the Belfiore Nicolini case, the court ruled partially in favor of the plaintiff. However, the Company is going to file an appeal to challenge said decision.

The Guillen Lopez case is currently before the lower court. As of March 31, 2017, the case remains pending resolution without further developments.

On October 3, 2016 the lower court ruled that the Hatamare Hual case had expired and declared the case concluded. The plaintiff has not filed an appeal before the Superior Court. On November 16, 2016, the Company´s Peruvian Branch requested for the case to be closed.

The potential contingency amount for these cases cannot be reasonably estimated by management at this time.

Special Regional Pasto Grande Project (“Pasto Grande Project”)

In 2012, the Pasto Grande Project, an entity of the Regional Government of Moquegua, filed a lawsuit against SCC’s Peruvian Branch alleging property rights over a certain area used by the Peruvian Branch and seeking the demolition of the tailings dam where SCC’s Peruvian Branch has deposited its tailings from the Toquepala and Cuajone operations since 1995. The Peruvian Branch has had title to use the area in question since 1960 and has constructed and operated the tailing dams with proper governmental authorization, since 1995. SCC’s Peruvian Branch asserts that the lawsuit is without merit and is vigorously defending against it. Upon a motion filed by the Peruvian Branch, the lower court has included MINEM as a defendant in this lawsuit. MINEM has answered the complaint and denied the validity of the claim. As of March 31, 2017, the case remains pending resolution without further developments. The amount of this contingency cannot be reasonably estimated by management at this time.

Carla Lacey and Barbara Siegfried, on behalf of themselves and all other similarly situated stockholders of Southern Copper Corporation, and derivatively on behalf of Southern Copper Corporation

A purported class action derivative lawsuit filed in the Delaware Court of Chancery was served on the Company and its Directors in February 2016 relating to the 2012 capitalization of 99.999% of MGE by Controladora de Infraestructura Energetica Mexico, S.A. de C.V., an indirect subsidiary of Grupo Mexico (the “CIEM Capitalization”), the Company’s entry into a power purchase agreement with MGE in 2012 (the “MGE Power Purchase Agreement”), and the 2012 restructuring of a loan from the Company’s Mexican Operations to MGE for the construction of two power plants to supply power to the Company’s Mexican operations (the “MGE Loan Restructuring”). The action purports to be brought on behalf of the Company and its common stockholders. The complaint alleges, among other things, that the CIEM Capitalization, the MGE Power Purchase Agreement and the MGE Loan Restructuring were the result of breaches of fiduciary duties and the Company’s charter. The Company has filed a response denying these allegations and is currently in the discovery process.

Labor matters:

Peruvian operations: 73% of the Company’s 4,589 Peruvian employees were unionized at March 31, 2017. Currently, there are five separate unions, one large union and four smaller unions. In the first quarter of 2016, the Company signed three-year agreements with all five unions. These agreements include, among other things, annual salary increases of 5% for each of the three years.

In April 2017, the unified labor union of SPCC workers and one of Toquepala’s unions began a stoppage, which was declared illegal by the Peruvian government. Even though the Company has always been in full compliance with the three-year labor agreements signed last year, these unions demanded a review of certain health and profit sharing benefits. During the stoppage, the Company deployed its emergency plan to maintain production with the use of temporary contractors. The stoppage concluded on April 22 with a decrease of only 1,418 tons of copper production and currently all the Company’s workforce has returned and operations are fully normalized.

Mexican operations: In recent years, the Mexican operations have experienced a positive improvement of their labor environment, as its workers opted to change their affiliation from the Sindicato Nacional de Trabajadores Mineros, Metalurgicos y Similares de la Republica Mexicana (the “National Mining Union”) to other less politicized unions.

However, the workers of the San Martin and Taxco mines, are still under the National Mining Union and 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, the Company filed a court petition on January 27, 2011 requesting that the court, among other things, define the termination payment for each unionized worker. The court denied the petition alleging

that, according to federal labor law, the union was the only legitimate party to file such petition. On appeal by the Company, on May 13, 2011, the Mexican federal tribunal accepted the petition. In July 2011, the National Mining Union appealed the favorable court decision before the Supreme Court. On November 7, 2012, the Supreme Court affirmed the decision of the federal tribunal. The Company filed a new proceeding before the labor court on the basis of the Supreme Court decision, which recognized the right of the labor court to define responsibility for the strike and the termination payment for each unionized worker. A favorable decision of the labor court in this new proceeding would have the effect of terminating the protracted strike at San Martin. As of March 31, 2017, the case remains pending resolution without further developments.

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 at the mine (including termination of 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 mining union appealed the labor court ruling before a federal court. In September 2011, the federal court accepted the union’s appeal and remanded the case to the federal labor court for reconsideration. After several legal proceedings on January 25, 2013, the Company filed a new proceeding before the labor court. On June 16, 2014, the labor court denied the petition of the Company. The resolution issued by the labor court was challenged by the Company before a federal court. In August 2015, the Supreme Court decided to assert jurisdiction over the case and to rule on it directly. As of March 31, 2017, the case remains pending resolution without further developments.

It is expected that operations at these mines will remain suspended until these labor issues are resolved.

In view of these lengthy strikes, the Company has reviewed the carrying value of the San Martin and Taxco mines to ascertain whether impairment exists. The Company concluded that there is a non-material impairment of the assets located at these mines.

Other legal matters:

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.

Other commitments:

Peruvian Operations

Tia Maria:

On August 1, 2014, the Company received the final approval of Tia Maria´s Environmental Impact Assessment (“EIA”). However, the issuance of the project´s construction permit has been delayed due to pressures from anti-mining groups. In 2016, the Company has continued working with community groups in order to resolve open issues concerning the project.

Tia Maria´s project budget is approximately $1.4 billion of which $363.9 million has been invested through March 31, 2017. When completed, it is expected to produce 120,000 tons of copper cathodes per year. This project will use state-of-the-art SX-EW technology with the highest international environmental standards. SX-EW facilities are the most environmentally friendly in the industry as they do not require a smelting process and consequently, no emissions are released into the atmosphere. The project will only use seawater, transporting this more than 25 kilometers to 1,000 meters above sea level, and includes a desalinization plant which will be constructed at a cost of $95 million. Consequently, the Tambo river water resources and the water resources from the wells in the area will be used solely for farming and human consumption.

The Company expects the project to generate 3,500 jobs during the construction phase. When in operation, Tia Maria will directly employ 600 workers and indirectly another 2,000. Through its expected twenty-year life, the project related services will create significant business opportunities in the Arequipa region.

In view of the delay in this project, the Company has reviewed the carrying value of this asset to ascertain whether impairment exists. Should the Tia Maria project not move forward, 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. The Company believes that an impairment loss, if any, will not be material.

Toquepala Concentrator Expansion:

In April 2015, the construction permit for the Toquepala expansion project was approved by the MINEM. The project budget is $1.2 billion, of which $623.4 million has been expended through March 31, 2017. When completed, this expansion project is expected to increase annual production capacity by 100,000 tons of copper and 3,100 tons of molybdenum.

Corporate Social Responsibility:

The Company has a corporate social responsibility policy to maintain and promote continuity of its mining operations and obtain the best results. The main objective of this policy is to integrate its operations with the local communities in the areas of influence of its operations by creating a permanent positive relationship with the communities to develop the optimum social conditions and to promote sustainable development in the area. Accordingly, the Company has made the following commitments:

Tacna Region: In connection with the Toquepala concentrator expansion, the Company has committed to fund various social and infrastructure improvement projects in Toquepala’s neighboring communities. The total amount committed for these purposes is S/ 445.0 million (approximately $132 million).

Moquegua Region: In the Moquegua region, the Company is part of a “development roundtable” in which the local municipal authorities, the community representatives and the Company discuss the social needs and the way the Company could contribute to sustainable development in the region. As part of this, the roundtable is discussing the creation of a Moquegua Region Development Fund for which the Company has offered a contribution of S/. 700 million (approximately $ 209 million). While final funding is not yet settled, the Company has committed to contribute S/ 108.5 million (approximately $32 million) in advance, which is being utilized in an educational project and S/. 48.4 million (approximately $14 million) for a residual water treatment plan in Ilo, a sea-wall embankment and a fresh water facility at El Algarrobal.

In addition, the Company has committed S/. 143.0 million (approximately $43 million) for the construction of five infrastructure projects in the Moquegua region under the “social investment for taxes” (obras por impuestos) program which allows the Company to use these amounts as an advance payment of taxes.

These commitments are subject to the continuity of the respective mine operations and, as such, are not considered to be present obligations of the Company. Therefore, the Company has not recorded a liability in its consolidated financial statements.

Power purchase agreements:

· Engie: In 1997, SCC signed a power purchase agreement with an independent power company, Engie Energia Peru S.A. (formerly Enersur S.A.) under which SCC agreed to purchase all of its power needs for its current Peruvian operations from Enersur for twenty years, through April 2017.

· Electroperu S.A.: In June 2014, the Company signed a power purchase agreement for 120 megawatt (“MW”) with the state power company Electroperu S.A., under which Electroperu S.A. will supply energy for the Peruvian operations for twenty years starting on April 17, 2017 and ending on April 30, 2037.

· Kallpa Generacion S.A. (“Kallpa”): In July 2014, the Company signed a power purchase agreement for 120MW with Kallpa, an independent Israeli owned power company, under which Kallpa will supply energy for the Peruvian operations for ten years starting on April 17, 2017 and ending on April 30, 2027. In May 2016, the Company signed an additional power purchase agreement for a maximum of 80MW with Kallpa, under which Kallpa will supply energy for the Peruvian operations related to the Toquepala Expansion and other minor projects for ten years starting on May 1, 2017 and ending after ten years of commercial operation of the Toquepala Expansion or on April 30, 2029; whichever happens first.

NOTE 10 — SEGMENT AND RELATED INFORMATION:

Company management views Southern Copper as having three reportable segments and manages it 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 Senior Management on the segment basis. Senior Management of the Company focus 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:

(*) NYSE closing price of SCC common shares at March 31, 2017.

As a result of the repurchase of shares of SCC’s common stock, Grupo Mexico’s direct and indirect ownership was 88.9% as of March 31, 2017. There was no activity in the SCC share repurchase program during the first quarter of 2017.

Parent Company common shares:

At March 31, 2017 and 2016 there were in treasury 112,457,204 and 118,278,037 of Grupo Mexico’s common shares, respectively.

Employee Stock Purchase Plan:

2010 Plan: During 2010, the Company offered to eligible employees a stock purchase plan through a trust that acquires series B shares of Grupo Mexico stock for sale to its employees, employees of subsidiaries, and certain affiliated companies. The purchase price was established at 26.51 Mexican pesos (approximately $1.28) for the initial subscription. Every two years employees were able to acquire title to 50% of the shares paid in the previous two years. The employees paid 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 granted the participant a bonus of one share for every ten shares purchased by the employee.

The participants were entitled to receive dividends in cash for dividends paid by Grupo Mexico for all shares that were fully purchased and paid by the employee as of the date that the dividend is paid. If the participant had only partially paid for shares, the entitled dividends were used to reduce the remaining liability owed for purchased shares.

In the case of voluntary or involuntary resignation/termination of the employee, the Company paid to the employee the fair market sales price at the date of resignation/termination of the fully paid shares, net of costs and taxes. When the fair market sales value of the shares was higher than the purchase price, the Company applied a deduction over the amount to be paid to the employee based on a decreasing schedule specified in the plan.

In case of retirement or death of the employee, the Company rendered the buyer or his legal beneficiary, the fair market sales value as of the date of retirement or death of the shares effectively paid, net of costs and taxes.

The stock based compensation expense for the first quarter 2017 and 2016 and the unrecognized compensation expense under this plan were as follows (in millions):

	2017		2016
Stock based compensation expense	$	0.1	$	0.1
Unrecognized compensation expense	$	0.7	$	1.3

The unrecognized compensation expense under this plan is expected to be recognized over the remaining one year and nine month period.

The purchase price was established at 38.44 Mexican pesos (approximately $1.86) for the initial subscription, which expires on January 2023. Every two years employees will be able to acquire title to 50% of the shares paid in the previous two years.

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 or involuntary resignation/termination 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 a decreasing schedule specified in the plan.

NOTE 12 — FINANCIAL INSTRUMENTS:

Subtopic 820-10 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 820-10 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 March 31, 2017 and December 31, 2016 (in millions):

	At March 31, 2017				At December 31, 2016
	Carrying Value		Fair Value		Carrying Value		Fair Value
Liabilities:
Long-term debt	$	5,954.9	$	6,491.8	$	5,954.2	$	6,212.0

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 except for the case of the Yankee bonds which qualify as Level 2 in the fair value hierarchy as they are based on quoted priced in market that are not active.

The Company’s short-term trading securities investments are classified as Level 1 because they are valued using quoted prices of the same securities as they consist of bonds issued by public companies and publicly traded. The Company’s short-term available-for-sale investments are classified as Level 2 because they are valued using quoted prices for similar investments.

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.

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 active ongoing exploration programs in Chile, 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, molybdenum, silver and zinc prices: In the first quarter of 2017, the average LME and COMEX copper prices were $2.65 per pound, about 25.0% and 25.6% higher than in the first quarter of 2016, respectively. During the first quarter of 2017 per pound LME spot copper prices ranged from $2.49 to $2.79. Average molybdenum, silver and zinc prices in the first quarter of 2017 increased 46.9%, 17.4% and 65.8%, respectively, when compared to the average prices in the first quarter of 2016.

· Sales structure: In the first quarter of 2017, approximately 81% of our revenue came from the sale of copper, 6% from molybdenum, 5% from silver, 5% from zinc and 3% from various other products, including gold, sulfuric acid and other materials.

· Copper: According to the International Monetary Fund, the world economy is accelerating to an estimated GDP growth of 3.4% in 2017 after a mark of 3.1% in 2016. The drivers of this growth are the cyclical recovery of manufacturing and international commerce. For 2017, we expect copper demand to grow about 2.0%, driven by China´s metals consumption recovery and a strong economy in the United States.

On the supply side, after five years of copper price reductions, we see supply underperforming market needs. We expect a weak growth in 2017, in the range of 0.5 to 1.0%. This lack of growth results from the decline in investments that several companies have had in recent years as well as technical problems, labor unrest, excess government taxation and other difficulties. All of these factors will cause the market deficit through 2017, giving good support to current copper prices.

· Silver: Represented 4.7% of our sales in the first quarter of 2017 and it is currently our third by-product. We believe that silver prices will have support due to its industrial uses as well as its linkage to gold as a value shelter in times of economic uncertainty.

· Molybdenum: Represented 5.9% of our sales in the first quarter of 2017. During the first quarter of 2017, the molybdenum price improved its level by 17.6% when compared to the fourth quarter of 2016 due to production cuts from major producers and additional demand coming from steel and oil drilling industry.

Molybdenum is mainly used for the production of special alloys of stainless steel that require significant hardness, corrosion and heat resistance. A new use for this metal is in lubricants and sulfur filtering of heavy oils and shale gas production.

· Zinc: Represented 5.0% of our sales in the first quarter of 2017. We also believe that zinc has very good long term fundamentals due to its significant industrial consumption and expected mine production shutdowns. In the last 12 months zinc inventories have consistently decreased, improving this market’s fundamentals.

· Production: For 2017, we expect to maintain our current production level of about 900,000 tons of copper. For 2018, we will initiate production at the new Toquepala concentrator and expect to be able to produce 972,300 tons of copper, continuing our aggressive organic growth program.

We also expect to produce 16.6 million ounces of silver, about 2.5% higher than the 2016 production of 16.2 million ounces due to higher Buenavista and IMMSA production. For zinc production, in 2017, we expect to produce 80,800 tons from our mines, up from 2016’s production, of 73,984 tons, mainly due to higher production from our Charcas, Santa Barbara and Santa Eulalia mines, which will increase their milling and forecast higher grades as well in 2017. Additionally, we expect to produce 20,300 tons of molybdenum, lower by 6.4% from last year’s production of 21,736 tons.

· Cost: Our operating costs and expenses for the first quarter 2017 and 2016 were as follows:

					Variance
	2017		2016		Value		%
Operating costs and expenses ($ in millions)	$	1,013.5	$	898.9	$	114.6	12.7	%

The increase was mainly due to higher cost of sales at our Mexican open-pit operations and higher depreciation, amortization and depletion at our Mexican operations, partially offset by lower exploration expenses and a $10.2 credit related to a previously accrued environmental remediation cost which was reversed in the first quarter of 2017.

· Capital Investments: In the first quarter of 2017 we spent $245.6 million on capital investments, 10.0% higher than in the first quarter of 2016, and represented 78.1% of net income. The year 2017 is the starting point of a new strategic plan: we will increase copper production capacity to exceed the one million ton milestone by mid-2018, and by 2023 we expect to reach 1.5 million tons of copper.

Illegal stoppage in our Peruvian Operations: In April 2017, the unified labor union of SPCC workers and one of Toquepala’s unions began a stoppage, which was declared illegal by the Peruvian government.. Even though we have always been in full compliance with the three-year labor agreements signed last year, these unions demanded a review of certain health and profit sharing benefits. During the stoppage, we deployed our emergency plan to maintain production with the use of temporary contractors. The stoppage concluded on April 22 with a decrease of only 1,418 tons of copper production and currently all our workforce have returned and operations are fully normalized.

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.

Table of Contents

Earnings: The table below highlights key financial and operational data of our Company for the three months ended March 31, 2017 and 2016 (in millions, except copper price, percentages and per share amounts):

	2017		2016		Variance		% Change
Copper price LME	2.65		2.12		0.53		25.0	%
Pounds of copper sold	487.7		469.3		18.4		3.9	%

Net sales	$	1,583.9	$	1,245.1	$	338.8	27.2	%
Operating income	$	570.4	$	346.2	$	224.2	64.8	%
Net income attributable to SCC	$	314.4	$	185.1	$	129.3	69.9	%

Dividends per share	$	0.08	$	0.03	$	0.05	166.7	%

Net sales and net income in the first quarter 2017 were higher than in the first quarter of 2016 by $338.8 million and $129.3 million, respectively. These increases were mainly the result of higher metal prices and higher sales volume of copper (+3.9%) and silver (+3.6%).

Production: The table below highlights our mine production data for the three months ended March 31, 2017 and 2016:

	2017	2016	Variance		% Change
Copper (in million pounds)	471.2	488.7	(17.5	)	(3.6	)%
Molybdenum (in million pounds)	11.6	12.3	(0.7	)	(5.3	)%
Silver (in million ounces)	4.0	4.1	(0.1	)	(2.4	)%
Zinc (in million pounds)	41.0	39.7	1.3		3.2	%

The table below highlights our copper production data for the three months ended March 31, 2017 and 2016:

COPPER (in million pounds)	2017	2016	Variance		% Change
Toquepala	78.3	79.4	(1.1	)	(1.4	)%
Cuajone	85.4	92.9	(7.5	)	(8.0	)%
La Caridad	69.6	72.9	(3.3	)	(4.4	)%
Buenavista	234.6	240.0	(5.4	)	(2.3	)%
IMMSA	3.3	3.5	(0.2	)	(5.2	)%
Total	471.2	488.7	(17.5	)	(3.6	)%

Mined copper production in the first quarter of 2017 decreased by 3.6% to 471.2 million pounds compared to 488.7 million pounds in the first quarter of 2016. This decrease was principally due to:

· Lower production at the Cuajone mine due to a decrease in ore grades and higher ore hardness index, which caused lower recoveries.

· Lower production at the Buenavista mine due to lower ore grades and lower SX-EW copper production, partially offset by a higher throughtput and better concentrate recoveries at the second concentrator.

· Lower production at the La Caridad mine, due to lower ore and concentrate grades.

Molybdenum production decreased 5.3% in the first quarter of 2017 to 11.6 million pounds, compared to 12.3 million pounds in the first quarter of 2016. Molybdenum production decreased in our Peruvian mines and at La Caridad mine due to lower ore grades. This was partially offset by higher production in our Mexican operations at the Buenavista mine due to higher output at the second concentrator.

Silver mine production decreased by 2.4% in the first quarter of 2017 mainly as result of lower production at our Buenavista and La Caridad mines, partially offset by higher production at our IMMSA and Toquepala mines.

Zinc production increased 3.2% in the first quarter of 2017, principally due to higher production at our Charcas mine.

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. This non-GAAP information should not be considered in isolation or as substitute for measures of performance determined in accordance with GAAP. A reconciliation of our operating cash cost per pound of copper produced to the cost of sales (exclusive of depreciation, amortization and depletion) as presented in the condensed consolidated statement of earnings is presented under the

Table of Contents

subheading, “Non-GAAP Information Reconciliation” on page 43. We disclose operating cash cost per pound of copper produced, both before and net of by-product revenues.

We define operating cash cost per pound of copper produced before by-product revenues as cost of sales (exclusive of depreciation, amortization and depletion), plus selling, general and administrative charges, treatment and refining charges net of sales premiums; less the cost of purchased concentrates, workers’ participation and other miscellaneous charges, including royalty charges, and the change in inventory levels; divided by total pounds of copper produced by our own mines.

We define operating cash cost per pound of copper produced net of by-product revenues as operating cash cost per pound of copper produced, as defined in the previous paragraph, less by-product revenues and net revenue (loss) on sale of metal purchased from third parties.

In our calculation of operating cash cost per pound of copper produced, before by-product revenues, we credit against our costs the revenues from the sale of all our by-products, including, molybdenum, zinc, silver, gold, etc. and the net revenue (loss) on sale of metals purchased from third parties. We disclose this measure including the by-product revenues in this way because we consider our principal business to be the production and sale of copper. As part of our copper production process, much of our by-products are recovered. These by-products, as well as the processing of copper purchased from third parties, are a supplemental part of our production process and their sales value contribute to cover part of our incurred fixed costs incurred. 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.

We believe that both of these measures are useful tools for our management and our stakeholders. Our cash costs before by-product revenues allow us to monitor our cost structure and address with operating management areas of concern. The measure operating cash cost per pound of copper produced net of by-product revenues is a common measure used in the copper industry and is a useful management tool that allows us to track our performance and better allocate our resources. This measure is also used in our investment project evaluation process to determine a project’s potential contribution to our operations, its competitiveness and its relative strength in different price scenarios. The expected contribution of by-products is generally a significant factor used by the copper industry in determining whether to move forward with the development of a new mining project. As the price of our by-product commodities can have significant fluctuations from period to period, the value of its contribution to our costs can be volatile.

Our operating cash cost per pound of copper produced, before and net of by-product revenues, is presented in the table below for the three months ended March 31, 2017 and 2016.

Operating cash cost per pound of copper produced (1)

(In millions, except cost per pound and percentages)

	2017			2016			Variance			% Change
Total operating cash cost before by-product revenues	$	679.7		$	672.4		$	7.3		1.1	%
Total by-products revenues	(275.9		)	(203.3		)	(72.6		)	35.7	%
Total operating cash cost net of by-products revenues	$	403.8		$	469.1		$	(65.3	)	(13.9	)%

Total pounds of copper produced (2)	457.0			478.2			(21.2		)	(4.4	)%

Operating cash cost per pound before by-product revenues	$	1.49		$	1.41		$	0.08		5.7	%
By-products per pound revenues	$	(0.61	)	$	(0.43	)	$	(0.18	)	41.9	%
Operating cash cost per pound net of by-products revenues	$	0.88		$	0.98		$	(0.10	)	(10.2	)%

(1) These are non-GAAP measures. Please see page 43 for reconciliation to GAAP measure.

(2) Net of metallurgical losses.

As seen in the table above, our per pound cash cost before by-product revenues in the first quarter of 2017 was $0.08 higher than in the same period of 2016. This 5.7% increase in operating cash cost was the result of higher treatment and refining charges and premiums, higher capitalized ore stockpiles on leach pads included in cost of sales and higher fuel and power costs; partially offset by lower costs per pound from selling, general and administrative expenses.

In addition, our per pound cash cost for the three months ended March 31, 2017 when calculated net of by-product revenues was $0.88 per pound, $0.10 lower than in the first quarter of 2016. This improvement was mainly the result of the higher prices for our major by-products.

Table of Contents

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.

We are subject to market risks arising from the volatility of copper and other metal prices. For the remaining nine months of 2017, assuming that expected metal production and sales are achieved, that tax rates are unchanged and giving no effect to potential hedging programs, metal price sensitivity factors would indicate the following change in estimated net income attributable to SCC resulting from metal price changes:

	Copper		Zinc		Molybdenum		Silver
Change in metal prices (per pound except silver — per ounce)	$	0.10	$	0.10	$	1.00	$	1.00
Change in net earnings (in millions)	$	85.6	$	10.6	$	19.5	$	6.8

Business Segments: We view our Company as having three reportable segments and manage it on the basis of these segments. These segments are (1) our 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 that 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” in this item and also in Note 10 “Segment and Related Information” of our condensed consolidated financial statements.

Inflation and Exchange Rate Effect of the Peruvian Sol and the Mexican Peso: Our functional currency is the U.S. dollar and our revenues are primarily denominated in U.S. dollars. Significant portions of our operating costs are denominated in Peruvian sol and Mexican pesos. Accordingly, when inflation and currency devaluation/appreciation of the Peruvian currency and Mexican currency occur, our operating results can be affected. In recent years, we do believe such changes have not had a material effect on our results and financial position. Please see Item 3. “Quantitative and Qualitative Disclosures about Market Risk” for more detailed information.

Capital Investment Programs: We made capital investments of $245.6 million in the three months ended March 31, 2017, compared with $223.3 million in the same period of 2016. In general, the capital investments and investment projects described below are intended to increase production, decrease costs or address social and environmental commitments.

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

Projects in Mexico:

Buenavista Projects - Sonora: These projects are increasing copper production from 180,000 tons to 500,000 tons. The Buenavista program was completed on time and $100 million below our budget. This program also includes the crushing, conveying and spreading system for leachable ore project (Quebalix IV), which has been completed on time at an estimated cost of $327 million, which is $117 million below our budget of $444 million. This project will reduce processing time as well as mining and hauling costs, increasing production by improving SX-EW copper recovery. The installed conveyor system is operating steadily.

Projects in Peru:

We are currently working on five copper projects in Peru, including the Tia Maria project, with a total capital investment for these projects of $2,900 million, out of which $1,206 million have been invested.

Toquepala Concentrator Expansion Project - Tacna: This $1.2 billion project includes a new state-of-the-art concentrator which will increase annual copper production by 100,000 tons to 217,000 tons in 2018 and 260,000 tons in 2019, and will also increase annual molybdenum production by 3,100 tons. Through March 31, 2017, we have invested $623.4 million in the project. The project has reached 58% progress and is expected to be completed in the second quarter of 2018.

Table of Contents

The project to improve the crushing process at Toquepala with the installation of a High Pressure Grinding Roll (HPGR) system, has as its main objective, to ensure that our existing concentrator will operate at its maximum milling capacity of 60,000 tons per day, even with an increase of the ore material hardness index. Additionally, recoveries will be improved and production enhanced with a better ore crushing. The budget for this project is $40 million and as of March 31, 2017, we have invested $27.6 million in this project. We expect that it will be completed by the first quarter of 2018.

Cuajone Projects — Moquegua: The Heavy Mineral Management Optimizing Project consists of installing a primary crusher at the Cuajone mine pit with a conveyor system for moving the ore to the concentrator. The project aims to optimize the hauling process by replacing rail haulage, thereby reducing operating and maintenance costs as well as the environmental impact of the Cuajone mine. The crusher will have a processing capacity of 43.8 million tons per year. The main components, including the crusher and the seven kilometer overland conveyor belt, have been acquired and assembled. As of March 31, 2017, we have invested $175.1 million in this project out of the approved capital budget of $215.5 million. The project has reached 91% progress and is expected to be completed by the third quarter of 2017.

The Cuajone tailing thickeners project at the concentrator will replace two of the three existing thickeners with a new hi-rate thickener. The purpose is to streamline the concentrator flotation process and improve water recovery efficiency, increasing the tailings solids content from 54% to 61%, thereby reducing fresh water consumption and replacing it with recovered water. As of March 31, 2017, we have completed the engineering and procurement process and continued the excavation and civil works. As of March 2017, we have invested $16.0 million in this project out of the approved capital budget of $30 million. The project has reached 74% progress and we expect it to be completed by the second quarter of 2017.

Tailings disposal at Quebrada Honda - Moquegua: 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 first stage and construction of the drainage system for the lateral dam is finished. We finished the engineering, and procurement is in progress. In order to improve and increase the dam’s embankment, we have assigned a construction contractor to install a new cyclone battery station that will allow us to place more slurry at the dams. The project has a total budgeted cost of $116.0 million. We have invested $75.6 million through March 31, 2017 and expect the project to be completed by the second quarter of 2018.

Potential projects

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.

Buenavista- Zinc concentrator: This zinc open-pit mine located in our Buenavista complex in Sonora, Mexico will produce 87,800 tons of zinc and 27,500 tons of copper content in concentrates per year with a capital budget of $360 million. Currently, we are reviewing the block model and the mine plan which are expected to be completed in 2017. Also, we are preparing the basic engineering and will request authorization to begin the detail engineering.

Pilares-La Caridad: This brownfield project located in Sonora, Mexico will produce 35,000 tons of copper per year with an initial capital budget of $200 million which we believe is still subject to further optimization. Pilares is an open-pit mine, located 6 kilometers away from our La Caridad complex. This relatively short distance will allow us to get synergies from the La Caridad infrastructure. We are working to define the mineral flow and on a trade-off analysis for a potential expansion of the La Caridad concentrator. In addition, we are analyzing mineral blending alternatives between Pilares and La Caridad in order to improve the copper grade of concentrates.

El Arco: This is a world class copper deposit located in the central part of the Baja California peninsula, with ore reserves over 2.7 billion tons with an ore grade of 0.399% and 0.11 grams of gold per ton. This project, includes an open-pit mine combining concentrator and SX-EW operations with an estimated production of 190,000 tons of copper and 105,000 ounces of gold annually. Between July 2015 and February 2016, we conducted a drilling program of 20,170 meters in order to further define the deposit at lower depths of between 300 and 600 meters. Through March 31, 2017 we have invested $77 million on studies, exploration and land acquisition for the project. Further exploration work is still required to better define the geometry of the deposit towards its west end and at the depths worked. In 2017, we expect to conduct further exploration activities. In addition, we will begin an engineering study to determine the best way to optimize the project and to update the feasibility study.

Table of Contents

El Pilar: This is a fully permitted, low capital intensity copper development project strategically located in Sonora, Mexico, approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and probable reserves of 325 million tons of ore with an average copper grade of 0.287%. El Pilar will operate as a conventional open-pit mine and copper cathodes will be produced using the highly cost efficient and environmentally friendly SX-EW technology. Average annual production is currently estimated at 35,000 tons of copper cathodes over an initial 13-year mine life, with start of commercial operations forecasted for 2019. On a preliminary basis, we estimate a development investment of approximately $310 million. In 2016, we conducted a diamond drilling program of 3,700 meters and a geophysical survey of 40 kilometers in order to confirm the reserves additionally, the results allow us to identify potential areas of interest of oxides and sulfures. In 2017, we expect to conclude the exploration in the north area and to continue with the metallurgical testing. In addition, we expect to begin the revised feasibility study and the project engineering.

Tia Maria: We have completed all engineering and have successfully obtained the approval of the environmental impact assessment for the project. We are currently working to obtain the construction license for this 120,000 tons of SX-EW copper per year project with a total capital investment of $1,400 million. In 2017, we are continuing with our social development programs with the neighboring communities.

This greenfield project, located in Arequipa, Peru, will use state of the art SX-EW technology with the highest international environmental standards. SX-EW facilities are the most environmentally friendly in the industry due to their technical process and consequently no emissions into the atmosphere are released. The project will use seawater, transporting it more than 25 kilometers and at 1,000 meters above sea level. The construction of the desalinization plant requires an investment of approximately $95 million.

We expect the project to generate 3,500 jobs during the construction phase. When in operation, Tia Maria will directly employ 600 workers and indirectly another 2,000. Through its expected twenty-year life, the project related services will create significant business opportunities in the Arequipa region. Tia Maria has complied with all existing requirements and regulations and therefore the Company trusts that it will soon receive from government authorities the construction licenses and permits required in order to begin construction of this project.

Los Chancas. This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit. Current estimates indicate the presence of 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 as well as, 181 million tons of mineralized leachable material with a total copper content of 0.357%. Los Chancas project includes an open-pit mine with a combined operation of concentrator and SX-EW processes to produce 100,000 tons of copper and 4,500 tons of molybdenum. The estimated capital investment is $2,800 million and is expected to be in operation in 2022. In 2016, we continued with the development of social and environmental programs with the local communities. As of March 31, 2017, we have initiated the bidding process to select the consulting firm for the elaboration of the environmental impact assessment.

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.

ACCOUNTING ESTIMATES

Our discussion and analysis of financial condition and results of operations, as well as quantitative and qualitative disclosures about market risks, are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. Preparation of these 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 period. We make our 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, ore stockpiles on leach pads and related amortization, estimated impairment of assets, asset retirement obligations, valuation allowances for deferred tax assets, unrecognized tax benefits and fair value of financial instruments. 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.

PROPOSED ACCOUNTING STANDARDS

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” (Topic 606). The objective of the new revenue standard is to provide a single comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets.

The core principle of the standard is that the Company should recognize revenue to represent the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services.

The Company should apply the following five steps to achieve the core principle:

Step 1: Identify the contract(s) with a customer.

Step 2: Identify the performance obligations (promises) in the contract.

Step 3: Determine the transaction price.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Step 5: Recognize revenue when (or as) the Company satisfies a performance obligation.

The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer. Additionally, the Company should disclose sufficient qualitative and quantitative information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

On July 9, 2015, the FASB approved a one year deferral of the effective date of the new revenue standard for all entities. This revenue standard is effective for the first interim period within annual reporting periods beginning after December 15, 2017, and early adoption is not permitted. The Company is evaluating the impact of the adoption of this new standard on the consolidated financial information.

IMPACT OF NEW ACCOUNTING STANDARDS

During the first quarter of 2017, the FASB issued, among others, the following six new accounting updates to the Codification.

ASU 2017-01: In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-01 “Business Combinations” Topic 805. This update adds guidance to assist entities with the evaluation of whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses.

The amendments in this Update are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. Early adoption is not permitted. As this guidance is specific to transactions related to acquisitions (or disposals) the effect on the financial statements will be subject to such events.

ASU 2017-03: In January 2017, the FASB issued ASU 2017-03 “Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323)”. These amendments have been made pursuant to SEC staff announcements at EITF meetings in September and November 2016. The amendments include a disclosure of the impact that recently issued accounting standards will have on the financial statements when adopted in a future period.

ASU 2017-04: In January 2017, the FASB issued ASU 2017-04 “Intangibles-Goodwill and Other (Topic 350)”. This amendment simplifies the test for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill.

The amendments in this Update modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Because these amendments eliminate Step 2 from the goodwill impairment test, they should reduce the cost and complexity of evaluating goodwill for impairment.

A public business entity that is a U.S. Securities and Exchange Commission (“SEC”) filer should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests after January 1, 2017.

ASU 2017-05: In February 2017, the FASB issued ASU 2017-05 “Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20)”. This Update clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets.

The amendments in this Update affect the following:

1. An entity that enters into a contract to transfer to a noncustomer a nonfinancial asset, a group of nonfinancial assets, or an ownership interest in a consolidated subsidiary that is not a business or nonprofit activity.

2. An entity that historically had transactions within the scope of the real-estate-specific derecognition guidance.

3. An entity that contributes nonfinancial assets that are not a business or a nonprofit activity to a joint venture or other non-controlled investee.

The amendments in this Update are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. While the Company believes that the adoption of this Update will not have a material effect on the Company’s financial statements, the Company is evaluating the Update.

ASU 2017-06: In February 2017, the FASB issued ASU 2017-06 “Plan Accounting: Defined Benefit Pension Plans (Topic 960); Defined Contribution Pension Plans (Topic 962); Health and Welfare Benefit Plans (Topic 965)”. This Update relates primarily to the reporting by an employee benefit plan for its interest in a master trust. A master trust is a trust for which a regulated financial institution serves as a trustee or custodian and in which assets of more than one plan sponsored by a single employer or by a group of employers under common control are held. The amendments in this Update clarify presentation requirements for a plan’s interest in a master trust and require more detailed disclosures of the plan’s interest in the master trust.

The amendments in this Update are effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. We do not expect that this update will have a significant effect on our financial statements.

ASU 2017-07: In March 2017, the FASB issued ASU 2017-07 “Compensation-Retirement Benefits (Topic 715)”. This Update is primarily to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. This Update also includes amendments to the Overview and Background Sections of the FASB codification.

The amendments in this Update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income separately from the service cost component and outside a subtotal of income from operations.

The amendments in this Update are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The Company does not believe that this Update will have a significant impact on the financial statements.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

Commodity price risk:

For additional information on metal price sensitivity, refer to “Metal Prices” in Part I, Item 2 of this quarterly report on Form 10-Q for the period ended March 31, 2017.

Foreign currency exchange rate risk:

Our functional currency is the U.S. dollar. Portions of our operating costs are denominated in Peruvian soles and Mexican pesos. Since our revenues are primarily denominated in U.S. dollars, when inflation or deflation in our Mexican or Peruvian operations is not offset by a change in the exchange rate of the sol or the peso to the dollar, our financial position, results of operations and cash flows could be affected by local cost conversion when expressed in U.S. dollars. In addition, the dollar value of our net monetary assets denominated in soles or pesos can be affected by exchange rate variances of the sol or the peso, resulting in a re-measurement gain or loss in our financial statements. Recent inflation and exchange rate variances are provided in the table below for the three months ended March 31, 2017 and 2016:

	2017		2016
Peru:
Peruvian inflation rate	1.86	%	1.14	%

Initial exchange rate	3.360		3.413
Closing exchange rate	3.249		3.328
Appreciation/(devaluation)	3.30	%	2.49	%

Mexico:
Mexican inflation rate	2.9	%	1.0	%

Initial exchange rate	20.664		17.207
Closing exchange rate	18.809		17.402
Appreciation/(devaluation)	8.98	%	(1.13	)%

Change in monetary position:

Assuming an exchange rate variance of 10% at March 31, 2017 we estimate our net monetary position in Peruvian sol and Mexican peso would increase (decrease) our net earnings as follows:

	Effect on net earnings
	($ in millions)
Appreciation of 10% in U.S. dollar vs. sol	$	2.4
Devaluation of 10% in U.S. dollar vs. sol	$	(3.0	)
Appreciation of 10% in U.S. dollar vs. Mexican peso	$	18.0
Devaluation of 10% in U.S. dollar vs. Mexican peso	$	(22.0	)

Open sales risk:

Our provisional copper and molybdenum sales contain an embedded derivative that is required to be separate from the host contract for accounting purposes. The host contract is the receivable from the sale of copper and molybdenum concentrates at prevailing market prices at the time of the sale. The embedded derivative, which does not qualify for hedge accounting, is marked to market through earnings each period prior to settlement. See Note 5 to our condensed consolidated financial statements for further information about these provisional sales.

Short-term Investments:

For additional information on our trading securities and available-for-sale investments, refer to “Short-term Investments” in Part I, Item 1 of this quarterly report on Form 10-Q for the period ended March 31, 2017.

Cautionary Statement:

Forward-looking statements in this report and in other Company statements include statements regarding expected commencement dates of mining or metal production operations, projected quantities of future metal production, anticipated production rates, operating efficiencies, costs and expenditures as well as projected demand or supply for the Company’s products. Actual results could differ materially depending upon factors including the risks and uncertainties relating to general U.S. and international economic and political conditions, the cyclical and volatile prices of copper, other commodities and supplies, including fuel and electricity, availability of materials, insurance coverage, equipment, required permits or approvals and financing, the occurrence of unusual weather or operating conditions, lower than expected ore grades, water and geological problems, the failure of equipment or processes to operate in accordance with specifications, failure to obtain financial assurance to meet closure and remediation obligations, labor relations, litigation and environmental risks as well as political and economic risk associated with foreign operations. Results of operations are directly affected by metal prices on commodity exchanges that can be volatile.

Item 4. Controls and Procedures

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of March 31, 2017, 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 (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). 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 March 31, 2017, 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 CONTROL OVER FINANCIAL REPORTING

There were no changes in the Company’s internal control 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 first quarter ended March 31, 2017 that have materially affected, or are 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 March 31, 2017, and the related condensed consolidated statements of earnings, comprehensive income and cash flows for the three-month periods ended March 31, 2017 and 2016. 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 reviews, 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, 2016, and the related consolidated statements of earnings, comprehensive income, changes in equity, and cash flows for the year then ended (not presented herein); and in our report dated March 1, 2017, 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, 2016 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
