NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

​

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”). As of March 31, 2022, 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 (“Southern Copper”, "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 fairly state the Company’s financial position as of March 31, 2022 and the results of operations, comprehensive income, cash flows and changes in equity for the three months ended March 31, 2022 and 2021. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full year. The December 31, 2021 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, 2021 and notes included in the Company’s 2021 annual report on Form 10-K.

​

​

CUAJONE STOPPAGE OF OPERATIONS

​

On February 28, 2022 a small group of protesters from the community of Tumilaca, Pocata, Coscore and Tala, which have 472 residents in total, seized the facilities at the Viña Blanca water reservoir and cut off the water supply to the homes of the approximately 5,000 people who live in Cuajone. Prior to this illegal action, on February 18, 2022, the railway between Cuajone and Ilo was also blocked by a group of community members. They claim the Company usurped their land and demand compensation of $5.0 billion, in addition to the permanent payment of 5% of net profits.

​

As of March 31, 2022, the Cuajone operations remained closed with an estimate production loss of 12,869 tonnes of copper content and 296 tonnes of molybdenum, which translates into a reduction in sales of $117 million. The Company also recorded $7.9 million of unabsorbed fixed costs, which directly impacted the cost of sales.

​

The effect on the Company´s net income and financial position was not material as of March 31, 2022. Sales contracts were not significantly affected and measures were taken to acquire concentrates from the Company´s Mexican Operations and third parties to maintain and adequate supply to the smelter. This prevented a force majeure event from delays in fulfilling the Company´s sales commitments.

​

As of March 31, 2022, the Company was expecting to enter into a dialogue with the protesters and the Peruvian authorities to secure an agreement to address reasonable social demands; restore the water supply to workers and their families, and resume operations at the Company Cuajone facilities. However, if this situation continues indefinitely, the Company may be forced to consider cost reduction measures, including the relocation or furlough of workers.

NOTE 4 — INCOME TAXES:

​

The income tax provision and the effective income tax rate for the first three months of 2022 and 2021 consisted of (in millions):

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021 | ​
Statutory income tax provision | ​ | $ | 511.6 | ​ | $ | 427.3 | ​
Peruvian royalty | ​ |  | 17.0 | ​ |  | 11.6 | ​
Mexican royalty | ​ |  | 58.0 | ​ |  | 47.4 | ​
Peruvian special mining tax | ​ |  | 25.5 | ​ |  | 21.2 | ​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Effective income tax rate | ​ | ​ | 43.8 | % | ​ | 40.1 | %

​

These provisions include income taxes for Peru, Mexico and the United States. The Mexican royalty, the Peruvian royalty and the Peruvian special mining tax are included in the income tax provision. The increase in the effective income tax rate in 2022 compared to the same period in 2021 was primarily attributable to the fact that the Company registered uncertain tax provisions in the Peruvian jurisdiction.

​

Peruvian royalty and special mining tax: The Company has accrued $42.5 million and $32.8 million of royalty charge and special mining tax as part of the income tax provision in the first quarter of 2022 and 2021, respectively.

​

​

Accounting for uncertainty in income taxes: In the first three months of 2022, the company recorded a receivable, current liability and non-current liability for the Peruvian jurisdiction that increased tax expense by approximately $33.8 million. The Company’s current asset and current liability for uncertain tax positions net to $22.1 million and represent the anticipated cash refunds or payments within 12 months.

​

Tax Law Changes:

On December 28, 2021, the U.S. Treasury and the IRS released final regulations addressing various aspects of the foreign tax credit regime. The regulations apply to years beginning after December 28, 2021 and they are not expected to have a material impact on the Company’s financial statements.

The Company assessed these derivative instruments as Cash Flow Hedges. As such, the effective portions of said hedges were initially reported in Other Comprehensive Income (OCI) and were reclassified as earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affected earnings. The Company did not identify any ineffective portions of these derivatives.

​

As of March 31, 2022 and the same period of 2021, the Company did not hold any derivative instruments.

NOTE 7 — LEASES:

​

The Company has operating leases for power generating facilities, vehicles and properties. The Company recognizes leasing expenses for these leases on a straight-line basis over the lease term. Some of the Company’s leases include both lease and non-lease components which are accounted for separately. The Company’s leases have remaining lease terms of one year to 11 years, and do not include options to extend the leases. The Company’s lease agreements do not contain options to purchase the leased assets or to terminate the leases before the expiration date. In addition, the Company’s lease contracts have no material residual value guarantees or material restrictive covenants. As none of the Company’s leases stipulates an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

Table of Contents

The weighted average remaining lease term for the Company’s leases is eight years, and the weighted average discount rate for these leases is 3.71%.

NOTE 8 — ASSET RETIREMENT OBLIGATION:

​

Peruvian operations:

​

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.

​

On June 24, 2019, MINEM approved a change to the guarantees required for the mining closure plans. The new regulation specifies that annual guarantees can be secured with real estate up to a maximum of 50% and the remaining amount with credit instruments. Currently, the Company has pledged the value of its Lima office complex for the 50% of the guarantee and with a stand-by letter of credit for the other 50% as a security for this obligation.Through January 2022, the Company has provided total guarantees of $66.3 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 March 2016, MINEM approved the Mining Closure Plan for the Toquepala expansion project and the revised closure plans for the Cuajone mine and the Ilo facilities were approved in January and October 2019 respectively. Based on these new estimates, the Company increased the asset retirement obligation by $28.1 million in 2019. The closure plan for the Tia Maria project was approved in February 2017. However, the Company has not recorded a retirement obligation for the Tia Maria project because work on the project is still on hold. The Company believes that under these circumstances, the recording of a retirement obligation is not appropriate.

Mexican operations:

​

The Company has recognized an estimated asset retirement obligation for its mining properties in Mexico as part of its environmental commitment. Even though there is currently no enacted law, statute, ordinance, written or oral contract requiring the Company to carry out mine closure and environmental remediation activities, the Company believes that a constructive obligation presently exists based on the remediation requirements caused by the closure of any facility. 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 the first quarter of 2022, the Company adjusted its estimate for the asset retirement obligation for its Mexican operations following a detailed review of the closing activities required. The effect was an increase in the asset retirement obligation to the order of $43.3 million.

​

The following table summarizes the asset retirement obligation activity for the first three months of 2022 and 2021 (in millions):

NOTE 9 — BENEFIT PLANS:

​

Post retirement defined benefit plans:

​

The Company has two non-contributory defined benefit pension plans to cover former salaried employees in the United States and certain former expatriate employees in Peru. Effective October 31, 2000, the Board of Directors amended the qualified pension plan to suspend the accrual of benefits.

​

In addition, the Company’s Mexican subsidiaries have a defined contribution pension plan for salaried employees and a non-contributory defined benefit pension plan for union employees.

​

The components of net periodic benefit costs for the first three months of 2022 and 2021 are as follows (in millions):

​

Post-retirement health care plans:

​

United States: The Company adopted a post-retirement health care plan for retired salaried employees eligible for Medicare in 1996. The Company manages the plan and is currently providing health benefits to retirees. The plan is accounted for in accordance with ASC 715 “Compensation retirement benefits”. As of December 31, 2021, because there has been a significant reduction in participants and in the amount of liability, the Company considered that this plan was not material enough to run a valuation.

​

In Mexico, health services are provided by the Mexican Social Security Institute.

NOTE 10 — COMMITMENTS AND CONTINGENCIES:

​

Environmental matters:

​

The Company has established comprehensive environmental conservation programs at its mining facilities in Peru and Mexico. The Company’s environmental programs include, 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, among others.

​

Environmental capital investments in the first quarter of 2022 and 2021 were as follows (in millions):

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021
Peruvian operations | ​ | $ | 1.4 | ​ | $ | 0.1
Mexican operations | ​ |  | 12.6 | ​ |  | 5.4
​ | ​ | $ | 14.0 | ​ | $ | 5.5

​

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 obligations, 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 8 “Asset retirement obligation” for further discussion of this matter.

​

Air Quality Standards (“AQS”): In June 2017, MINAM enacted a supreme decree that defined new AQS for daily sulfur dioxide in the air. As of March 31, 2022, the Company maintains a daily average level of µg/m3 of SO2, lower than those required by the new AQS.

​

Soil Environmental Quality Standards (“SQS”): In 2013, the Peruvian government enacted Soil Quality Standards. In accordance with the regulatory requirements of the law, the Company prepared Soil Decontamination Plans (“SDP”) for environmentally impacted sites at each of its operation units (Toquepala, Cuajone and Ilo) with the assistance of consulting companies. The costs of these SDPs are not material, either individually or in aggregated form, for the financial statements of the Company.

​

Climate change: On April 17, 2018, the Peruvian government enacted Law N. 30754, establishing a Climate Change

Framework. This law establishes that it is in the national interest to promote public and private investments in climate change management. The law proposes creating an institutional framework to address climate change in Peru, and outlines new measures, particularly with respect to climate change mitigation. For example, it includes provisions addressing an increase in carbon capture and use of carbon sinks, afforestation and reforestation practices; land use changes; and sustainable systems of transportation, solid waste management, and energy systems. This is the first Latin American climate change framework law to incorporate obligations from the Paris Agreement. Regulations to this law were enacted by Supreme Decree 013-2019 published on December 31, 2019, and are applicable to all Peruvian institutions and agencies. It is expected that further Peruvian regulations will be applicable to non-governmental entities. However, no carbon pricing mechanism is currently applicable to the Company’s operations in Peru.

Table of Contents

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 to provide an individual or entity the ability to challenge 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. Additionally, amendments to the Civil Federal Procedures Code (“CFPC”) were enacted in 2011, and established three categories of collective actions under which a group of 30 or more individuals may be considered sufficient to prove a “legitimate interest” to file civil actions for injuries arising out of alleged violations of environmental, consumer protection, financial services and economic competition laws. The group can seek restitution or economic compensation for the alleged injuries or suspension of the activities which allegedly caused the injuries in question. 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. This law establishes general guidelines for actions to be considered likely to 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. If restoration is not possible, compensation measures must be provided. Criminal penalties and monetary fines may be imposed under this law.

​

On February 2019, the Mexican Supreme Court confirmed the constitutionality of an ecological tax on extractive activities conducted in the state of Zacatecas, which taxes environmental remediation actions, emissions of certain gases to the atmosphere, emissions of polluting substances to the soil or water, and waste storage within the state. The Company has determined that this new environmental regulation will have no impact on its financial position.

​

Guaymas sulfuric acid spill: On July 9, 2019, there was an incident at the Company´s Marine Terminal in Guaymas, Sonora, that caused the discharge of approximately three cubic meters of sulfuric acid into the sea in the industrial port area.

​

The Guaymas bay has an estimated water volume of 340 million cubic meters. The spill, upon entering in contact with the sea’s alkaline conditions, led to quick dilution of the discharge. Thus, the sulfuric acid was naturally and immediately neutralized. As a result, the discharge was considered harmless; the report from the Ministry of Navy found that neither the flora nor fauna of the port area were affected.

​

On July 10, 2019, PROFEPA made a first inspection of the area, concluding that the Company executed all the appropiate procedures in order to contain the discharge, and no reference was made to the existence of negative impacts on the environment resulting from the incident.

​

On Friday, July 19, 2019, PROFEPA revisited the facilities to carry out a second inspection and declared a partial temporary shutdown that only affected the storage process and transportation of sulfuric acid at the terminal, arguing the absence of an authorization of environmental impact. It is important to note that these facilities have been in operation since 1979, prior to the 1988 Mexican General Law of Ecological Balance and the Protection of the Environment. Companies that were operating before the aforementioned law are exempt from the permit requirement. In addition, in 2009, PROFEPA awarded a certification of “Clean Industry and Environmental Quality” to the facility which was subsequently renewed four times (for a two-year period each time).

Table of Contents

The Company filed a lawsuit against the closure, which was dismissed by a ruling on August 25, 2021. This ruling has been challenged through a motion to reopen the case, which was submitted on September 28, 2021. On January 4, 2022, the challenge was resolved. The authority imposed two fines and ruled that the temporary closure would remain in place until the environmental impact statement is obtained. The Company intends to appeal this ruling

​

The Company is not aware of the reasons or causes for this partial and temporary closure, but will continue working with the environmental authorities to provide assurance that the operation is in strict compliance with environmental regulations. The Company expects the environmental authorities to suspend the partial temporary shutdown, once their concerns are resolved. Currently, the Company does not expect any impact on its operations. As of March 31, 2022, the matter is pending resolution.

​

Climate change: Several taxes are applicable to the Company’s mining operations in Mexico, including federal and state fossil fuel taxes, and the requirements associated with Mexico’s emission trading scheme. These taxes range from $2.5/tCO2 to $12.5/tCO2, approximately. These refer to regional taxes applicable in the States of Baja California and Zacatecas, as well as a federal tax linked to Mexico’s carbon market system which is currently in its pilot phase. The requirements associated with this scheme are currently applicable only to two business units, the metallurgic and lime plants in Sonora, which generate annual GHG emissions levels above the threshold of 100,000 tCO2e per year contemplated by the scheme. These business units are required to report and verify their emissions once a year with average costs of less than $6,000 per unit. Units that emit more than 25,000 tonnes CO2 equivalent per year (all our Mexican units) are required to report their emissions to the National Emissions Registry (RENE) every year and to verify the reported emissions every three years. As a result, the Company’s total annual compliance costs related to climate change regulations in Mexico were not material to the Company.

​

The Company has also been participating in Mexico’s “GHG Program” since its inception in 2005, which is a voluntary initiative for the registry and reporting of greenhouse gases emissions.

​

The Company believes that all of its facilities in Peru and Mexico are in material compliance with environmental, mining and other applicable laws and regulations. The Company also believes that continued compliance with environmental laws of Mexico and Peru will have no material adverse effects on the Company’s business, properties, or operating results.

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 that approved the Environmental Impact Assessment of the project; (ii) the cancellation of the project and the withdrawal of mining activities in the area; (iii) to declare null and void the mining concession application for the Tia Maria project; and (iv) to declare null and void the resolution that approved the construction license. 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), Junta de Usuarios del Valle del Tambo (filed April 30, 2015), and Gobierno Regional de Arequipa (filed December 16, 2019).

​

The del Carpio Lazo 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.

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, since 1995, constructed and operated the tailings dams with proper governmental authorization. Following a motion filed by the Peruvian Branch, the lower court included MINEM as a defendant in this lawsuit. MINEM has answered the complaint and denied the validity of the claim. As of March 31, 2022, the case was pending resolution without further developments.

The Accidental Spill at Buenavista Mine of 2014

​

In relation to the 2014 accidental spill of copper sulfate solution at a leaching pond in the Buenavista mine, the following legal procedures are pending against the Company:

​

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 environmental damages. During the second quarter of 2018, the criminal complaint was dismissed. This decision was appealed and was pending resolution as of March 31, 2022.

​

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. Three of the collective action lawsuits have been dismissed by the

court. As of March 31, 2022, three lawsuits are still pending: two were filed by Acciones Colectivas de Sinaloa, A.C. and one by Defensa Colectiva, A.C., requesting precautionary measures in the construction of facilities to monitoring public health services and prohibiting the closure of the Rio 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 similar 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 thirty-three additional civil action lawsuits, claiming similar damages. The 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 Dominguez 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 Bustamante; Rodolfo Barron Villa et al, Jose Carlos Martinez Fernandez et al, Maria de los Angeles Fabela et al; Rafaela Edith Haro et al; Luz Mercedes Cruz et al; Juan Pedro Montaño et al; and Juana Irma Alday Villa. In the first quarter of 2018, BVC was served with another civil action lawsuit, claiming similar damages. The lawsuit was filed by Alma Angelina Del Cid Rivera et al. In the last quarter of 2018, BVC was served with other three civil action lawsuits, claiming similar damages. These lawsuits were filed by Los Corrales de la Estancia, S.C. de R.L.; Jose Antonio Navarro; Jesus Maria Peña Molina, et al; these actions were dismissed by the court, because they have expired. As of March 31, 2022, forty-five cases remain pending resolution.

​

In 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 to the spill in August 2014. The plaintiffs in these lawsuits are: Francisca Garcia Enriquez, et al filed two lawsuits, Francisco Ramon Miranda, et al and Jesus David Lopez Peralta et al. In the third quarter of 2016, four additional constitutional lawsuits, claiming similar damages were filed by Mario Alberto Salcido et al; Maria Elena Heredia Bustamante et al; Martin Eligio Ortiz Gamez et al; and Maria de los Angeles Enriquez Bacame et al. In the third quarter of 2017, BVC was served with another constitutional lawsuit filed by Francisca García Enriquez et al. In 2018, BVC was served with two additional constitutional lawsuits that were filed against SEMARNAT by Norberto Bustamante et al. With regard to the constitutional lawsuit filed by Maria Elena Heredia Bustamante et al; in which it was claimed the lack of community approval regarding the authorization granted by SEMARNAT to build the new BVC tailings dam, on September 5, 2018, the Supreme Court of Justice issued a resolution establishing that such authorization was granted to BVC in compliance with the applicable legislation. However, SEMARNAT must carry out a public meeting to inform the community of the technical aspects required to build the dam, potential impacts and prevention measures. This public meeting will have no material effects to BVC’s operations. SEMARNAT has carried out the consultation ordered by the Supreme Court. As a result, it has informed the corresponding Judge its compliance with the resolution, in which BVC was required to implement additional measures of environmental impact prevention, such as: (i) the building of at least three monitoring wells downstream from the curtain of the contingency dam in a period of six months; (ii) monitoring of the groundwater level and water quality every six months; (iii) carrying out rain collection work in order to restore water to the Sonora River basin, with six months granted to present the execution program; (iv) determine the location of wildlife conservation and protection areas and define the need to establish biological corridors; (v) obtain photographic or videographic evidence every six months; (vi) submitting to SEMARNAT two years before the closure and abandonment of the site, or earlier if necessary, the closure program that includes the cleaning and restoration of the soil including Mexican regulation NOM-141; (vii) include the measures in the Environmental Monitoring Program according to the environmental components impacted; and (viii) hiring an external environmental consultant to validate compliance

with the current and new conditions imposed. The foregoing does not impact BVC’s operations. Additionally, the lawsuits filed by Maria de los Angeles Enriquez Bacame and Norberto Bustamante have been dismissed and closed without prejudice to the Company. As of March 31, 2022, the remaining cases were still pending resolution.

​

It is currently not possible to determine the extent of the damages sought in these state and federal lawsuits but the Company believes that these lawsuits are without merit. Accordingly, the Company is vigorously defending against them. Nevertheless, the Company believes 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.

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

​

In April 2019, a derivative lawsuit was filed against the Company, certain current and former Directors, and Grupo Mexico in the Delaware Court of Chancery relating to certain construction contracts, contracts for the purchase and sale of minerals, and transportation contracts entered into between the Company’s subsidiaries and subsidiaries of Grupo Mexico.

​

In October 2019, the plaintiff amended the complaint to include claims related to certain administrative services contracts between the Company’s subsidiaries and Grupo Mexico. The amended complaint alleges, among other things, that the construction, mineral, transportation, and administrative services contracts were unfair as a result of breaches of fiduciary duties and the Company’s charter. The amended complaint also added Americas Mining Corporation (“AMC”) as a defendant, alleging that AMC breached its fiduciary duties as a controlling stockholder of the Company. The amended complaint seeks, among other things, unspecified monetary damages. In January 2020, the Company, the current and former Directors, and Grupo Mexico responded to the complaint by filing motions to dismiss. The Plaintiff filed a brief in response to the motions on March 13, 2020. On July 16, 2020, the Court denied the motions to dismiss the breach of fiduciary duty claims against the Directors. On October 6, 2020, the Court dismissed the Plaintiff’s claims against Grupo Mexico for lack of personal jurisdiction. On February 11, 2021, the Court granted the Directors’ motion to dismiss plaintiff’s breach of contract claim. The Court also granted AMC’s motion to dismiss all claims against AMC other than those related to the mineral contracts.

​

On July 12, 2021, the parties reached an agreement-in-principle to settle the lawsuit, subject to Court approval. On September 29, 2021, the parties filed a Stipulation and Agreement of Compromise, Settlement and Release with the Court. On February 1, 2022, the Judge approved the settlement and awarded certain fees to the plaintiff’s attorneys. The Judge’s order for this decision was registered on February 2, 2022. Under applicable law, there was a 30-day period for parties to appeal the Judge's order. This period expired on March 4, 2022, and therefore the Judge's order is considered final.

Labor matters:

​

Peruvian operations: 72.8% of the Company's 4,675 Peruvian employees were unionized at March 31, 2022. Currently, there are six separate unions, none of which represents the majority of workers, as defined by current Peruvian labor legislation.

​

During 2021, the Company decided to hold talks with the six unions to sign collective agreements prior to their effective dates. As a result, between June and December 2021, the Company signed collective agreements with the six unions with durations between three to six years. All of them granted annual salary increases of 5%. Additionally, each agreement granted, among other things, a signing bonus of between S/45,000 (approximately $12,159) and S/90,000 (approximately $22,318), depending on the duration of the agreement. A long-term agreement bonus of S/10,000

(approximately $2,702) was granted to the union that signed a six-year extension of the collective bargaining agreement. All these concepts were recorded as labor expense.

​

As of March 31, 2022, the Company has no pending negotiations with Peruvian unions.

​

Mexican operations: In recent years, the Mexican operations have experienced a positive improvement in their labor environment, as 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.

The workers of the San Martin mine were on strike since July 2007. On February 28, 2018, the striking workers of the San Martín mine of IMMSA held an election to vote on the union that would hold the collective bargaining agreement at the San Martín mine. The Federacion Nacional de Sindicatos Independientes (the National Federation of Independent Unions) won the vote by a majority. Nevertheless, the vote was challenged by the National Mining Union. On June 26, 2018, the Federal Mediation and Arbitration Board issued a ruling recognizing the election results. Due to the agreement between workers and the Company to end the protracted strike, on August 22, 2018, the Federal Mediation and Arbitration Board authorized the restart of operations of the San Martín mine. Such authorization was challenged by the National Mining Union. On April 4, 2019, the Federal Mediation and Arbitration Board recognized, once again, the election results from February 28, 2018, by which the National Federation of Independent Unions won by a majority. In the last quarter of 2019, a Federal Court issued a resolution that established that the Labor Court should analyze the list of workers with the right to vote in the union election. The Company and the National Federation of Independent Unions challenged such determination before the Supreme Court of Justice. Such challenges were dismissed by the Supreme Court. As a consequence, on September 6, 2021, the Federal Mediation and Arbitration Board issued a new resolution determining that, based on the documents submitted by the National Federation of Independent Unions and given the status of the strike until 2018, it was not possible to create a registry of workers holding a right to vote. Therefore, in case of a strike, any economic collective proceedings shall remain suspended. The Federal Mediation and Arbitration Board shall decide on the request of the majority of workers to end the strike, despite the opposition of the National Mining Union. The Company expects that the conflict will be solved in accordance with the legal framework set by labor authorities and that any actions taken will respect the workers’ will.

​

As of March 31, 2022, the Company had completed most of the rehabilitation plan to restore operations at the San Martin mine, at a total expense of approximately $90.5 million; the mine has since reached full operating capacity.

​

In the case of the Taxco mine, its workers have been on strike since July 2007. After several legal procedures, in August 2015, the Supreme Court decided to assert jurisdiction over the case and to rule on it directly. As of March 31, 2022, the case was pending resolution without further developments.

​

It is expected that operations at the Taxco mine will remain suspended until the labor issues are resolved. In view of the lengthy strike, the Company has reviewed the carrying value of the Taxco mine to ascertain whether impairment exists. The Company concluded that there is a non-material impairment of the assets located at this mine.

​

In 2020, a small group of workers at the Charcas mine claimed an additional workers’ participation payment and a minor incident was reported. This claim lacked legal basis given that the Company had already completely fulfilled said obligation with the workers in question. Consequently, the Company took legal action and through conciliation and mediation with labor authorities, the incident concluded with no further repercussions for the Company.

​

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.

Peruvian Operations:

​

Tia Maria

​

On August 1, 2014, the Company received final approval for Tia Maria´s Environmental Impact Assessment (“EIA”). On July 8, 2019, the Company received the construction permit for this 120,000 ton annual SX-EW copper greenfield project with a total capital budget of $1,400 million. This permit was obtained after completing an exhaustive review process, complying with all established regulatory requirements and addressing all observations raised.

​

On July 15, 2019, anti-mining groups staged a violent demonstration affecting economic as well as other activities in the Islay province. These actions were followed by the filing of three complaints, sponsored by groups opposing the Tia Maria project, with the Mining Council, which is the Peruvian administrative authority responsible for ruling on these complaints. The Mining Council temporarily suspended the construction permit on August 8, 2019. On October 7, 2019, as part of the process, the Mining Council conducted a hearing to hear the complaints and the Company´s position. On October 30, 2019, the Mining Council of the Peruvian Ministry of Energy and Mines ratified the construction permit for the Tia Maria project.

​

The Company has been working to promote the welfare of the Islay province population. As part of these efforts, the Company has implemented social programs in education, healthcare and productive development to improve the quality-of-life in the region. The Company also has promoted agricultural and livestock activities in the Tambo Valley and supported growth in manufacturing, fishing and tourism in Islay.

​

During the construction and operation phase, the Company will make it a priority to hire local labor to fill the 9,000 jobs (3,600 direct and 5,400 indirect) that the Company expects to generate during Tia Maria’s construction phase. When operating, the Company expects Tia Maria to directly employ 600 workers and indirectly provide jobs for another 4,200. Additionally, from day one of its operations, the Company will generate significant contributions to revenues in the Arequipa region via royalties and taxes.

​

Tia Maria´s project budget is approximately $1.4 billion, of which $332.3 million had been invested as of March 31, 2022. 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 therefore, do not release any emissions into the atmosphere.

​

Michiquillay

​

In June 2018, the Company signed a contract for the acquisition of the Michiquillay copper project in Cajamarca, Peru, at a purchase price of $400 million. Michiquillay is a world-class mining project with estimated inferred mineral resources of 2,288 million tonnes with an estimated copper grade of 0.43%. It is expected to produce 225,000 tonnes of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years.

​

On September 3, 2021, the Company signed a social agreement with the Michiquillay community. On October 1, 2021, the Peruvian Ministry of Energy and Mines approved the semi-detailed environmental impact study for the project. Additionally, on November 12, 2021, the Company signed a Social Agreement with the Encañada Community. These events will allow the Company to initiate an in-depth exploration program in the second quarter of 2022.

​

The main commitments signed by the Company in the social agreements with the Michiquillay project communities are related to providing support for agricultural and livestock activities, economic development of local initiatives, and social programs in favor of education, water management, waste disposal, and healthcare for vulnerable groups.

​

The Company paid $12.5 million at the signing of the contract. In June 2021, the Company made an additional payment of $12.5 million. The balance of $375.0 million will be paid if the Company decides to develop the project, which is not a present obligation.

Corporate Social Responsibility

​

The Company has a corporate social responsibility policy to maintain and promote the continuity of its mining operations and obtain the best results. The main objective of this policy is to integrate the Company´s operations with local communities in the areas of influence of its operations by creating permanent positive relationships to develop optimum social conditions and 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 funding various social and infrastructure improvement projects in Toquepala’s neighboring communities. The total amount committed for these purposes is S/445.0 million (approximately $120.2 million). In relation to this commitment, the Company has recently completed the construction of a school with an investment of S/18.8 million (approximately $5.1 million), has co-financed the construction of the Cularjahuira dam for S/15.6 million (approximately $4.2 million) and is preparing the study of engineering for the Callazas dam for S/2.6 million (approximately $0.7 million).

​

As the Toquepala expansion project has been completed, the Company considers that these commitments constitute present obligations of the Company and consequently has recorded a liability of $34.6 million in its condensed consolidated financial statements as of March 31 2022.

​

In addition, the Company has committed S/70.3 million (approximately $19.0 million) for the construction of a high-performance school in the Tacna 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.

​

Moquegua Region: In the Moquegua region, the Company participates in a “development roundtable” with local municipal authorities and community representatives to discuss social needs and to determine the ways that the Company can contribute to sustainable development in the region. Currently, the roundtable is discussing the creation of a Moquegua Region Development Fund, for which the Company has offered a contribution of S/1,000 million (approximately $270.2 million). While final funding is not yet settled, the Company has committed to contribute S/108.4 million (approximately $29.3 million) as an advance, which is being utilized to fund an educational project. In addition, there is a commitment to finance the construction of a residual water treatment plant in Ilo for S/79.9 million (approximately $21.6 million), to build three schools in Moquegua for S/15.9 million (approximately $4.3 million) and to build tracks and sidewalks in Pacocha for S/6.4 million (approximately $1.7 million).

​

In addition, the Company has committed S/100.4 million (approximately $27.1 million) to build two 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.

SCC share repurchase program:

​

In 2008, the Company’s Board of Directors (“BOD”) authorized a $500 million share repurchase program that has since been increased by the BOD and is currently authorized to $3 billion. Pursuant to this program, the Company has purchased 119.5 million shares of common stock at a cost of $2.9 billion. These shares are available for general corporate purposes. The Company may purchase additional shares of its common stock from time to time, based on market conditions and other factors. This repurchase program has no expiration date and may be modified or discontinued at any time.

​

There has been no activity in the SCC share repurchase program since the third quarter of 2016. The NYSE closing price for SCC common shares as of March 31, 2022 was $75.90 and the maximum number of shares that the Company could purchase at that price was 1.1 million.

NOTE 12 — FAIR VALUE MEASUREMENT:

​

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, which 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, 2022 and December 31, 2021 (in millions):

​

Total long-term debt | ​ | $ | 6,548.5 | ​ | $ | 7,721.6 | ​ | $ | 6,547.6 | ​ | $ | 8,573.2

​

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 prices in markets that are not active.

​

Fair values of assets and liabilities measured at fair value on a recurring basis were calculated as follows as of March 31, 2022 and December 31, 2021 (in millions):

​

Provisionally priced sales: At March 31, 2022, the Company has recorded provisionally priced sales of copper at average forward prices per pound, and molybdenum at the March 31, 2022 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, 2022:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Sales volume |  | Priced at |  | ​
​ | ​ | (million lbs.) | ​ | (per pound) | ​ | Month of settlement
Copper | ​ | 201.9 | ​ | 4.71 | ​ | April 2022 through July 2022
Molybdenum | ​ | 13.9 | ​ | 19.30 | ​ | April 2022 through June 2022

​

The provisional sales price adjustment included in accounts receivable and net sales as of March 31, 2022 includes positive adjustments of $29.4 million for copper and $3.3 million for molybdenum.

​

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

​

​

NOTE 14 — 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, types 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 types of customers for their products and services and each group incurs expenses independently, including commercial transactions between groups.

​

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

​

​

Cuajone mine restore of operations:

​

After several unsuccessful attempts by the authorities to restore order through dialogue, on April 20, 2022, the Peruvian government declared a state of emergency in the Moquegua region. On April 21, 2022, the protesters returned the installations of the Viña Blanca water reservoir and the railway to the Company. The Company’s personnel immediately evaluated the damage caused to the facilities by acts of vandalism and took the necessary steps to resume production at the Cuajone mining unit. As of today, the industrial railroad and the Cuajone mine, concentrator and related facilities are operating at full capacity.

​

On April 30, 2022, the Peruvian government issued a Ministerial Resolution to set up a three-party-round-table for dialogue with members of the community, government and Company officers to better understand all parties’ concerns.

Additionally, the following discussion and analysis should be read in conjunction with the Management Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements included in Part II of our annual report on Form 10-K for the year ended December 31, 2021.

​

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 and our principal operations are in Peru and Mexico. We also have 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 through a number of dedicated mining facilities in Mexico.

​

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

​

● | Sales structure: In the first quarter of 2022, approximately 78.0% of our revenue came from the sale of copper; 10.0% from molybdenum; 3.8% from silver; 3.6% from zinc; and 4.6% from various other products, including gold, sulfuric acid and other materials.

​

● | Copper: In the first quarter of 2022, the LME copper price increased from an average of $3.85 per pound in the first quarter of 2021 to $4.53 (+17.7%). Currently, we are seeing prices in the range of $4.40 to $4.50, which remains higher than the 2021 average of $4.23 per pound and bodes a positive outlook for the Company. We believe the following factors are influencing the market:

​

| ● | The most relevant market intelligence houses for the copper market are expecting a market deficit for 2022 of about 100,000 tonnes.

| ● | This assumes growth in demand of 2.0 -2.5% in 2022, particularly in terms of cathode consumption in the U.S. An economic slowdown is expected in China due to the recent COVID-19 outbreak.

| ● | Uncertainty regarding future production growth in Chile and Peru, which together represent about 40% of the global supply. Chile registered a production drop of 7.0% in the first quarter of 2022, while 20% of Peru’s production is currently at risk due to social conflicts.

| ● | Russia’s copper supply (about 400,000 tonnes per year) has been shut out of the market due to the invasion of Ukraine.

​

● | Molybdenum: Represented 10.0% of our sales in the first quarter of 2022 and is currently our most important by-product. Molybdenum prices averaged $18.99 per pound in the first quarter of 2022, compared to $11.19 in the same period of 2021. This represented a 69.7% increase.

​

Regarding this by-product, we believe that prices will be supported by lower exports from China; an uptick in delivery times; and port congestion. We expect these factors will help maintain prices at good levels.

​

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

​

● | Silver: Represented 3.8% of our sales in the first quarter of 2022. We believe that the prices for silver will be supported by its intensive level of industrial use and the fact that, like gold, it represents value shelter in times of economic turmoil.

​

● | Zinc: Represented 3.6% of our sales in the first quarter of 2022. We consider zinc has very good long term fundamentals due to high levels of industrial consumption and expected production.

​

● | Production: For 2022, we expect to produce 895,800 tons of copper, which represents a decrease of 6.5% compared to 2021. Production will continue to be affected by the stoppage at Cuajone and by the temporary reduction in ore grades and recoveries at the Peruvian operations.

​

We expect our copper production to bounce back in 2023 and reach 971,200 tonnes as we get Peruvian production back on track and generate new production through our projects at Pilares and Buenavista-Zinc Concentrator.

​

We also expect to produce 25,300 tonnes of molybdenum, which represents a decrease of 16.4% over our 2021 production levels. In 2022, we expect to produce 18.7 million ounces of silver, which represents a slight decrease of 2.4% over our 2021 production level. Additionally, we expect to produce 69,700 tonnes of zinc from our mines, up 4.1% from 2021 production.

​

● | Capital Investments: In the first quarter of 2022, we spent $205.2 million on capital investments; this represented 25.6% of net income and an decrease of 11.8% compared to the amount registered for the same period in 2021.

​

​

CYBERSECURITY

​

Our operations depend upon information technology systems that may be subject to disruption, damage or failure from different sources, including, without limitation, installation of malicious software, computer viruses, security breaches, cyber-attacks and defects in design. In recent years, cybersecurity incidents have increased in frequency and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and the corruption of data. We have implemented appropriate preventative measures to mitigate potential risks by implementing an information security management system, which ensures application of controls that are frequently reviewed and tested.

​

In March 2021, we experienced a Ransomware cyber-attack, which was conducted by individual hackers. This cyber-attack encrypted a total of 420 servers and units of personal equipment. However, due to the quick response of our IT team, our Enterprise Resource Planning software was not affected by the aforementioned attack.

​

After the attack, we immediately began a remediation and recovery process and completely restored the affected servers. The forensic investigation did not identify concrete evidence that any information was stolen during the attack. However, we maintain active lines of cyberintelligence and continue to monitor the DarkWeb/DeepWeb and social networks to identify any publication or activity related to the Company to validate the technological controls affected during the attack and ensure that our systems infrastructure remains secure.

​

In March 2021, we appointed a new head of the Information Technology Department, who implemented a new information security strategy to ensure business continuity based on processes (controls and corporate governance framework), technology and human capital (organizational culture). In July 2021, Grupo Mexico appointed a Chief Information Security Officer, who has been actively involved in the development and implementation of this information security strategy. In addition, from July to September of 2021, we performed a cybernetic forensic

37

analysis with the assistance of a professional consulting firm with international experience in this area. The recommendations received were integrated in current information security programs.

​

Additionally, AMC set up a task force to oversee ongoing initiatives and ensure that targets are met. We are actively following this matter with the task force, our internal audit team and; will also require the expertise of third parties.

​

Our new information security strategy is being executed on a continuous basis. The compliance, internal control, information technology and internal audit departments are all working together to integrate reference frameworks, risk management models and the necessary controls to continue executing this strategy and corresponding programs. To support our commitment to the strategy, we are working under the international framework for reference and standard, such as ISO, COBIT and NIST, to certify the Company´s security systems. The Company has also established an information security culture with the purpose of training, communicating and maintaining permanent awareness among the workforce. On the governance framework side, the Company has created a Committee of Information Security and set up security policies and standards, among other actions.

​

For 2022 we have a non-material special budget to continue improvements in this area.

​

CUAJONE STOPPAGE OF OPERATIONS

​

On February 28, 2022, a small group of protesters from the community of Tumilaca, Pocata, Coscore and Tala, which have of 472 residents in total, seized the facilities at the Viña Blanca water reservoir and cut off the water supply to the homes of the approximately 5,000 people who live in Cuajone. Prior to this illegal action, on February 18, 2022, the railway between Cuajone and Ilo was also blocked by a group of community members. They claim, the Company usurped their land and demand compensation of $5.0 billion, in addition to the permanent payment of 5% of net profits.

​

As of March 31, 2022, the Cuajone operations remained closed with an estimated production loss of 12,869 tonnes of copper content and 296 tonnes of molybdenum, which translates into a reduction in sales for $117. We also recorded $7.9 million of unabsorbed fixed costs, which directly impacted the cost of sales.

​

The impact to our results and financial position is not material as of March 31, 2022. Sales contracts were not significantly affected and measures were taken to acquire concentrates from our Mexican Operations and third parties to maintain and adequate supply to the smelter. This prevented a force majeure event from delays in fulfilling our sales sales commitments.

​

After several unsuccessful attempts by the authorities to restore order through dialogue efforts, on April 20, 2022, the Peruvian government declared a state of emergency in the Moquegua region. On April 21, 2022, the protesters returned the installations of the Viña Blanca water reservoir and the railway to the Company. Our personnel immediately evaluated the damage caused to the facilities by acts of vandalism and took the necessary steps to resume production at the Cuajone mining unit. As of today, the industrial railroad and the Cuajone mine, concentrator and related facilities are operating at full capacity.

​

On April 30, 2022, the Peruvian government issued a Ministerial Resolution to set up a three-party-round-table for dialogue with members of the community, government and Company officers to better understand all parties’ concerns.

​

ECONOMIC CONSEQUENCES OF RUSSIA´S INVASION OF UKRAINE

​

The Ukraine-Russia war that broke out in February of 2022, has generated a series of impacts in the global economy and on international trade. This has forced companies to adjust their supply and commercial plans to deal with shipping delays for goods and higher prices for the same. The increase in the cost of oil and energy, coupled with saturation at ports, which was already high due to a surge in global economic activity after the COVID-19 pandemic ebbed, has driven up the prices of the vast majority of products and generated uncertainty in economies. This

situation is also affecting the countries in which we operate and in which our clients and suppliers operate, although the extent of the impact varies.

​

As of March 31, 2022, the impact of these events were not material for the Company due to our continuing cost efficiency programs. We are monitoring and adjusting our supply schedules to reflect the delay in the delivery of our critical supplies. Currently, our sales program has suffered no impacts.

​

​

KEY MATTERS

​

Below, we discuss several matters that we believe are important to understand the results of our 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.

​

Earnings: The table below highlights key financial and operational data of our Company for the three months ended March 31, 2022 and 2021 (in millions, except copper price, percentages and per share amounts):

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | Three months ended March 31, |
​ |  | 2022 |  | 2021 |  | Variance | ​ | % Change |  | ​
Copper price LME | ​ | ​ | 4.53 | ​ | ​ | 3.85 | ​ | ​ | 0.68 |  | 17.7 | % | ​
Pounds of copper sold | ​ | ​ | 458.4 | ​ | ​ | 529.6 | ​ | ​ | (71.2) |  | (13.4) | % | ​
Net sales | ​ | $ | 2,763.8 | ​ | $ | 2,532.5 | ​ | $ | 231.3 |  | 9.1 | % | ​
Operating income | ​ | $ | 1,470.1 | ​ | $ | 1,351.6 | ​ | $ | 118.5 |  | 8.8 | % | ​
Net income attributable to SCC | ​ | $ | 784.7 | ​ | $ | 763.8 | ​ | $ | 20.9 | ​ | 2.7 | % | ​
Earnings per share | ​ | $ | 1.02 | ​ | $ | 0.99 | ​ | $ | 0.03 | ​ | 3.0 | % | ​
Dividends per share | ​ | $ | 1.00 | ​ | $ | 0.60 | ​ | $ | 0.40 | ​ | 66.7 | % | ​

​

Net sales in the first quarter of 2022 were 9.1% higher than in the same period of 2021, which was primarily attributable to higher metal prices for copper (+17.7%), molybdenum (+69.7%) and zinc (+36.0%), as well as to an increase in the sales volume of zinc (+98.8%). This was offset by a decrease in silver (-8.5%) prices as well as decreases in sales volume of copper (-13.4%), molybdenum (-2.4%) and silver (-16.8%).

​

Net income attributable to SCC in the first quarter of 2022 was 2.7% higher than in the same period of 2021. This growth was mainly attributable to the increase in metal prices and sales volumes mentioned above.

​

Production: The table below highlights our mine production data for the three months ended March 31, 2022 and 2021:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Total mined copper | ​ | 472.8 |  | 525.6 |  | (52.8) |  | (10.0) | % |

​

First quarter: Mined copper production in the first quarter of 2022 fell by 10.0% to 472.8 million pounds compared to 525.6 million pounds in the first quarter of 2021. This was mainly attributable to a drop in production at our Cuajone (-38.5%), Toquepala (-12.6%), La Caridad (-10.8%) and IMMSA (-20.4%) mines due to lower grades. This effect was offset by higher production at our Buenavista (+2.5%) mine due to higher ore grades.

​

Molybdenum production decreased 2.3% in the first quarter of 2022 compared to the levels registered in the first quarter of 2021. This was attributable to an increase in production at our Toquepala (+9.0%) and Buenavista (+15.8%) mines due to higher ore grades and recoveries. This effect was partially offset by a decrease in production at the Cuajone (-42.0%) and La Caridad (-2.2%) mines due to lower ore grades.

​

Silver mine production decreased 13.4% in the first quarter of 2022 due to a drop in production at the Toquepala (-24.4%), Cuajone (-34.8%), La Caridad (-5.7%) and IMMSA (-15.1%) operations. This was offset by a higher production at the Buenavista (+2.6%) mine.

​

Zinc production decreased 10.6% in the first quarter of 2022 compared to the same period of 2021. This decrease was mainly attributable to lower production at the Santa Barbara (-12.5%), San Martin (-11.0%) and Charcas (-8.5%) mines.

​

Operating Cash Costs: An overall benchmark that we use, which is 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 consolidated statement of earnings is presented under the subheading, “Non-GAAP Information Reconciliation” on page 53. 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.

​

In our calculation of operating cash cost per pound of copper produced, we exclude depreciation, amortization and depletion, which are considered non-cash expenses. Exploration is considered a discretionary expenditure and is also excluded. Workers’ participation provisions are determined on the basis of pre-tax earnings and are also excluded. Additional exclusions from operating cash costs are items of a non-recurring nature and the mining royalty charge as it is based on various calculations of taxable income, depending on which jurisdiction, Peru or Mexico, is imposing the charge. We believe these adjustments allow our management and stakeholders to more fully visualize our controllable cash cost, which we believe is one of the lowest of all copper-producing companies of similar size.

​

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.

40

Table of Contents

​

In our calculation of operating cash cost per pound of copper produced, net of 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 covering part of our incurred fixed costs. 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 areas of concern within operating management. 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 to determine whether to move forward or not in 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, 2022 and 2021:

​

Operating cash cost per pound of copper produced (1)

(1) | These are non-GAAP measures. Please see page 53 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 2022 was 21.2% higher than in the same period of 2021. This increase was mainly attributable to an increase in production costs. Our cash cost per pound net of by-product revenue for the first quarter of 2021 decreased 25.7% when compared to the same period of 2021. This was mainly attributable to a significant increase in by-product revenues.

​

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, and for copper, molybdenum, zinc and silver in particular.

​

We are subject to market risks arising from the volatility of copper and other metal prices. For the remaining nine months of 2022, assuming that expected metal production and sales are achieved, tax rates remain unchanged and no

effects are generated by 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 |  | Molybdenum |  | Zinc |  | Silver
Change in metal prices (per pound except silver—per ounce) | ​ | $ | 0.10 | ​ | $ | 1.00 | ​ | $ | 0.10 | ​ | $ | 1.00
Change in net earnings (in millions) | ​ | $ | 85.2 | ​ | $ | 24.5 | ​ | $ | 10.8 | ​ | $ | 8.5

​

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, 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 14 “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 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 $205.2 million in the three months ended March 31, 2022, compared to $232.6 million in the same period of 2021. 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 by utilizing cash on hand; internally generated funds and additional external financing, including funding received in September 2019. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy, market conditions or the COVID-19 pandemic.

​

Projects in Mexico:

​

Buenavista Zinc - Sonora: This project is located within the Buenavista facility and includes the development of a new concentrator to produce approximately 100,000 tonnes of zinc and 20,000 tonnes of copper per year. We have completed the engineering study. In order to continue with the project, stronger preventive measures to combat COVID-19 have been put in place. Procurement has progressed 99% and all the main equipment is on site. Construction site works are in progress. The project has all the necessary permits. The project´s budget is $413 million, and we expect to initiate operations in the second half of 2023. As of March 31, 2022, we had invested $240.5 million in this project. When completed, we anticipate that this new facility will double the Company’s zinc production capacity and will provide 490 direct jobs and 1,470 indirect jobs.

​

Pilares - Sonora: Located six kilometers from La Caridad, this project consists of an open-pit mine operation with an annual production capacity of 35,000 tonnes of copper in concentrate. A new 25-meter wide off-road facility for mining trucks has been built and will be used to transport the ore from the pit to the primary crushers at the La Caridad copper concentrator. This project will significantly improve the overall mineral ore grade (combining the 0.78% expected from Pilares with 0.34% from La Caridad). The budget for Pilares is $159 million of which we have invested $79.5 million as

42

Table of Contents

of March 31, 2022. The project has obtained all permits and licenses required and we expect to begin production in the last quarter of 2022.

​

El Pilar - Sonora: This low-capital intensity copper greenfield project is strategically located in Sonora, Mexico, approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and probable reserves of 317 million tonnes of ore with an average copper grade of 0.249%. We anticipate that El Pilar will operate as a conventional open-pit mine with an annual production capacity of 36,000 tonnes of copper cathodes. This operation will use highly cost efficient and environmentally friendly SX-EW technology. We estimate a development investment of approximately $310 million. The results from experimental pads in leaching process have confirmed adequate levels of copper recovery. We expect this project to start production in 2024 with an expected mine life of 13 years. The basic engineering study is finished and the Company continues developing project and site environmental activities.

​

Lime plant - Sonora: As part of our cost improvement projects, we are building a new lime plant with a production capacity of 600 metric tonnes per day, which will be the largest lime plant of Mexico. This facility will allow us to reduce to approximately 50% our current lime cost at our Mexican operations. The total budget for the plant is $63.1 million, of which we have spent $46.2 million as of March 31, 2022. We expect this project initiate operations in the third quarter of 2022.

​

Projects in Peru:

​

Quebrada Honda dam expansion – Tacna: This project aims to enlarge the main and lateral dams in Quebrada Honda and includes the relocation and repowered of some facilities due to dam growth and implementation of other facilities for water recovery, among other factors. As of March 31, 2022, pre-commissioning and commissioning activities are in progress with work on three fronts. This project has a total budget of $179.4 million, of which we have invested $146.2 million as of March 31, 2022.

​

Tia Maria - Arequipa: On July 8, 2019, we were granted the construction permit for this 120,000 tonne annual SX-EW copper greenfield project with a total capital budget of $1,400 million. The Government awarded the permit after completing an exhaustive review process, complying with all established regulatory requirements and addressing all observations raised. The challenges surrounding the construction permit were overcome when on October 30, 2019, the Mining Council of the Peruvian Ministry of Energy and Mines ratified the construction permit for the Tia Maria project.

​

The Company has been consistently working to promote the welfare of the Islay province population. As part of these efforts, we have implemented successful social programs in education, healthcare and productive development to improve the quality-of-life in the region. We also have promoted agricultural and livestock activities in the Tambo Valley and supported growth in manufacturing, fishing and tourism in Islay.

​

In 2021, SPCC fortified its relation with the regional government and successfully overcame its opposition to project initiation. This new consensus was reflected in an agreement for “works for taxes” for projects relative to health facilities and roads. Our efforts to ensure the current and long-term welfare of the population in the area of influence of the Tia Maria project were recognized by several local associations, which sent letters to the National Government to request project initiation.

​

We reiterate our view that the initiation of construction activities at Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region. During the construction and operation phase, we will make it a priority to hire local labor to fill the 9,000 jobs (3,600 direct and 5,400 indirect) that we expect to generate during Tia Maria’s construction phase. When operating, we expect Tia Maria to directly employ 600 workers and indirectly provide jobs for another 4,200. Additionally, from day one of our operations, we will generate significant contributions to revenues in the Arequipa region via royalties and taxes.

​

We expect the Peruvian government to continue to acknowledge the significant progress the project has made on the social front and the important contributions that Tia Maria will generate for Peru´s economy and, consequently, take the necessary steps to provide SCC with adequate support to initiate construction.

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 with no emissions released into the atmosphere.

​

Potential projects

​

We have a number of other projects that we may develop in the future. We continuously 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, market conditions or the COVID-19 pandemic.

​

El Arco - Baja California: This is a world-class copper deposit located in the central part of the Baja California peninsula with ore reserves of over 1, 230 million tonnes with an average ore grade of 0.40% and 141 million tonnes of leach material with an ore grade of 0.27%. The project includes an open-pit mine with a combined concentrator and SX-EW operations. Annual production is expected to total 190,000 tonnes of copper and 105,000 ounces of gold with an estimated capital budget of $2.9 billion. The Company has started the baseline study and is reviewing the basic engineering analysis to request the environmental impact permit. Several years back, we began to acquire the rights to all relevant mining concessions in the area; this process was completed in 2020.

​

Los Chancas - Apurimac: This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit. Current estimates of indicated copper mineral resources are 98 million tonnes of oxides with a copper content of

0.45% and 52 million tonnes of sulfides with a copper content of 0.59%. Los Chancas project envisions an open-pit mine with a combined operation of concentrator and SX-EW processes to produce 130,000 tonnes of copper and 7,500 tonnes of molybdenum anually. The estimated capital investment is $2,600 million and the project is expected to be in operation in 2027. In the first quarter of 2022, we continued to engage in social and environmental improvements for the local communities and we worked on the environmental impact assessment for the project.

​

Michiquillay Project - Cajamarca: On June 12, 2018, Southern Copper signed a contract and made an initial payment of $12.5 million for the acquisition of the Michiquillay project in Cajamarca, Peru. In June 2021, the Company paid an additional $12.5 million to acquire the project. The Company has created a multidisciplinary management team to plan the development of this project. As part of this plan, the Company has established venues of contact with the local and regional authorities and communities to promote programs for the sustainable development in the area. On September 3, 2021, the Company signed a Social Agreement with the Michiquillay Community and on November 12, 2021, the Company signed a Social Agreement with the Encañada Community. Additionally, on October 1, 2021 the Peruvian Ministry of Energy and Mines approved the semi-detailed Environmental Impact Study for the project.

​

The Social Agreements with the Michiquillay and the Encañada communities represent an opportunity to improve the quality of life of the residents of those communities via our strong social programs and backed by a solid framework for technical work at the project level. These events are important steps that will allow Southern Copper to initiate an in-depth exploration program in the second quarter of 2022.

​

Michiquillay is a world class mining project with inferred mineral resources of 2,288 million tonnes with an estimated copper grade of 0.43%. When developed, we expect Michiquillay to produce 225,000 tonnes of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years, at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2028 and that Michiquillay will become one of Peru´s largest copper mines. The project will create significant business opportunities in the Cajamarca region; generate new jobs for the local communities and contribute with taxes and royalties to the local, regional and national governments.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (“ESG”)

​

In line with our sustainability strategy, we registered on-going improvement in our main sustainability indicators. In terms of safety, we reduced the accident rate of our own personnel and contractors by 22% in the last three years. With reference to the main environmental indicators, our Scope 1 and 2 greenhouse gas emissions have been reduced by more than 10%, while the efficiency in the consumption of fresh water in the concentrators has increased by 4% over the period. Regarding social matters, the population served through our community programs has tripled, while we continue to strengthen the mechanisms for listening and addressing their concerns.

​

In an effort to provide certainty to our investors and stakeholders, we present our progress regarding third-party validation of our environmental and social practices. We continue with the process of certifying our occupational health and safety management systems under the international standard ISO 45001 and our environmental management systems under ISO 14001 at all of our mining units. In the first quarter of 2022, the Santa Barbara and San Martin mines received an ISO 45001 certification and the La Caridad Mine and the Lime Plant in Sonora, received an ISO 14001 certification.

​

Regarding our climate change management, the company is now positioned above average for the sector and region, in view of the fact that Grupo Mexico rose two levels, from level C to level B, in the evaluation of the Carbon Disclosure Project (CDP) in 2021.

​

The communities surrounding our operations in Peru consist of dozens of small towns that live from the high Andean desert region to the Pacific coast. We continue to address the challenges and needs of these communities including water supply, education and employment. Investments in infrastructure for water supply are noteworthy, representing 70% of the $93.6 million invested in the last ten years. In the first quarter of 2022, the construction of the Cularjahuira dam in the province of Candarave, in the area of influence of our Toquepala mine, was completed; which will store up to 2.55 million cubic meters of water to irrigate 500 hectares of agricultural land and will directly benefit 585 families of local farmers.

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, determination of discount rates related to the financial lease liabilities, classification of operating leases versus financial leases, 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 reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

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, 2022.

​

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, 2022 and 2021:

​

​ | ​ | ​ | ​ | ​ | ​
​ |  | Three Months Ended |
​ | ​ | March 31, | ​
​ |  | 2022 |  | 2021 |
Peru: |  |  |  |  |
Peruvian inflation rate |  | 1.8 | % | 1.5 | %
Initial exchange rate |  | 3.998 |  | 3.624 |
Closing exchange rate |  | 3.701 |  | 3.758 |
Appreciation/(devaluation) |  | 7.4 | % | (3.7) | %
Mexico: |  |  |  |  |
Mexican inflation rate |  | 2.4 | % | 2.3 | %
Initial exchange rate |  | 20.584 |  | 19.949 |
Closing exchange rate |  | 19.994 |  | 20.605 |
Appreciation/(devaluation) |  | 2.9 | % | (3.3) | %

​

Change in monetary position:

​

Assuming an exchange rate variance of 10% at March 31, 2022, we estimate our net monetary position in Peruvian sol and Mexican peso would increase (decrease) our net earnings as follows:

​ | ​ | ​ | ​
​ |  | Effect in net
​ |  | earnings
​ |  | ($ in millions)
Appreciation of 10% in U.S. dollar vs. Peruvian sol | ​ | $ | 23.7
Devaluation of 10% in U.S. dollar vs. Peruvian sol | ​ | $ | (28.9)
Appreciation of 10% in U.S. dollar vs. Mexican peso | ​ | $ | 3.0
Devaluation of 10% in U.S. dollar vs. Mexican peso | ​ | $ | (3.7)

​

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 13 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, 2022.

Table of Contents

Derivative Instruments:

​

From time to time, we use derivative instruments to manage our cash flows exposure to changes in commodity prices. We do not enter into derivative contracts unless we anticipate that the possibility exists that future activity will expose our future cash flows to deterioration. Derivative contracts for commodities are entered into to manage the price risk associated with forecasted purchases of the commodities that we use in our manufacturing process.

​

Cash Flow Hedges of Natural Gas

​

Our objective in using natural gas derivatives is to protect the stability of natural gas costs and manage exposure to natural gas price increases. To protect natural gas costs from estimated price increases in the past winter season, we acquired two derivative instruments that began in November 2021 and ended in March 2022.

​

Derivative instruments and its effects as of March 31, 2002, were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​
Derivatives designated as hedging instruments under ASC 815 | ​ | Call Option | ​ | Financial Swap Cash Settlement | ​
Commodity contracts | ​ | Natural gas | ​ | Natural gas | ​
Gas volume (MMBTUs) | ​ | 5,285,000 | ​ | 5,285,000 | ​
Hedge premium ($per MMBTU) | ​ | 0.55 | ​ | - | ​
Reference price (swap: $per MMBTU)) | ​ | Prior month average IFREC price | ​ | 3.75 | ​
Hedge | ​ | Daily fluctuation range | ​ | Monthly average price | ​
​ | ​ | 1Q 2022 | November 2021 - March 2022 | ​ | 1Q 2022 | November 2021 - March 2022 | ​
Cost (million $) | ​ | (1.7) | (2.9) | ​ | - | - | ​
Profit (million $) | ​ | 0.5 | 0.5 | ​ | 1.7 | 4.7 | ​
Net favorable/unfavorable effect (million $) | ​ | (1.2) | (2.4) | ​ | 1.7 | 4.7 | ​
​ | ​ | 1Q 2022 | ​ | November 2021 - March 2022 | ​
Combined profit (million $) | ​ | 0.5 | ​ | 2.3 | ​

​

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

We assessed these derivative instruments as Cash Flow Hedges. As such, the effective portions of said hedges are initially reported in Other Comprehensive Income (OCI) and were reclassified as earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affected earnings. The Company did not identify any ineffective portions of these derivatives.

​

As of March 31, 2022 and the same period of 2021, we did not hold any derivative instruments.

​

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, 2022, 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, 2022, 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 three months ended March 31, 2022 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:

​

Results of Review of Interim Financial Statements

​

We have reviewed the accompanying condensed consolidated balance sheet of Southern Copper Corporation and subsidiaries (the “Company”) as of March 31, 2022, the related condensed consolidated statements of earnings, comprehensive income and cash flows for the three-month periods ended March 31, 2022, and 2021, and the related notes (collectively referred to as the “interim financial information”). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it 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) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2021, and the related consolidated statements of earnings, comprehensive income, and cash flows for the year then ended (not presented herein); and in our report dated March 7, 2022, 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, 2021 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

​

Basis for Review Results

​

This interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

​

We conducted our reviews in accordance with standards of the PCAOB. 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 PCAOB, the objective of which is the expression of an opinion regarding the condensed consolidated interim financial statements taken as a whole. Accordingly, we do not express such an opinion.

PART II — OTHER INFORMATION

​

Item 1. Legal Proceedings:

​

The information provided in Note 10 “Commitments and Contingencies” to the condensed consolidated financial statements contained in Part I of this Form 10-Q, is incorporated herein by reference.

​

Item 1A. Risk Factors:

​

The Company's operations and financial results are subject to various risks and uncertainties, including those described in “Risk Factors” included in Part I, Item 1A of our Annual report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 7, 2022. The following supplements and updates the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021.

​

Potential delays in transportation of products to customers and possible shortages of critical parts, equipment, and other resources may adversely affect our results of operations.

​

Current challenges in the global shipping industry have led to congestion in ports, a shortage in containers, and a lack of space on ships. Because of this situation, the Company faces a risk of potential supply chain disruptions that may adversely affect our operations and development projects. To address this potential issue, we have increased our safety stock levels and adjusted our replacement algorithms. Additionally, our revenues and collections may also be adversely affected by transportation delays that could have a negative impact on our sales agreements. Although the recovery of the global economy is causing the aforementioned issues at ports and in the shipping industry, this situation is expected to be resolved gradually and to return to normal levels in the short term. However, if these issues continue for a longer period, our supply chain and our sales flow could be adversely impacted.

​

Our mining operations or metal production projects may be subject to stoppage and additional costs due to community actions and other factors.

​

In recent months, the political action of certain groups in Peru has caused an increase in violence in the demands of certain communities, which has affected Cuajone's operations. On February 28, 2022, a small group of protesters from the community of Tumilaca, Pocata, Coscore and Tala, which have 472 residents in total, seized the facilities at the Viña Blanca water reservoir and cut off the water supply to the homes of the approximately 5,000 people who live in Cuajone. Prior to this illegal action, on February 18, 2022, the railway between Cuajone and Ilo was also blocked by a group of community members.

​

After several unsuccessful attempts by the authorities to restore order through dialogue efforts, on April 20, 2022, the Peruvian government declared a state of emergency in the Moquegua region. On April 21, 2022, the protesters returned the installations of the Viña Blanca water reservoir and the railway to the Company. Our personnel immediately evaluated the damage caused to the facilities by acts of vandalism and took the necessary steps to resume production at the Cuajone mining unit. As of today, the industrial railroad and the Cuajone mine, concentrator and related facilities are operating at full capacity.

​

On April 30, 2022, the Peruvian government issued a Ministerial Resolution to set up a three-party-round-table for dialogue with members of the community, government and Company officers to better understand all parties’ concerns.

​

However, if there is a recurrence of such incidents, we cannot guarantee that they will not adversely impact other facilities, the results of our operations; and our financial position.

Item 2. Unregistered Sale of Equity Securities and Use of Proceeds:

​

SCC share repurchase program:

​

In 2008, the Company’s BOD authorized a $500 million share repurchase program that has since been increased by the BOD and is currently authorized to $3 billion. Pursuant to this program, the Company has purchased 119.5 million shares of common stock at a cost of $2.9 billion. These shares are available for general corporate purposes. The Company may purchase additional shares of its common stock from time to time, based on market conditions and other factors. This repurchase program has no expiration date and may be modified or discontinued at any time.

​

The NYSE closing price of SCC common shares as of March 31, 2022 was $75.90 and the maximum number of shares that the Company could purchase at that price was 1.1 million. 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, 2022. There has not been any activity in the SCC share repurchase program since the third quarter of 2016.
