​

NOTE 4 — INCOME TAXES:

​

The income tax provision and the effective income tax rate for the nine-month periods ended September 30, 2022 and 2021 consisted of (in millions):

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021 | ​
Statutory income tax provision | ​ | $ | 972.7 | ​ | $ | 1,387.0 | ​

It is anticipated that in the future the Company will enter into similar transactions with these same parties.

​

NOTE 6 — DERIVATIVE INSTRUMENTS:

​

From time to time, the Company uses derivative instruments to manage its cash flows exposure to changes in commodity prices. The Company does not enter into derivative contracts unless it anticipates that the possibility exists that future activity will expose the Company’s 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 the Company uses in its manufacturing process.

​

Cash Flow Hedges of Natural Gas

​

The Company’s 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, the Company acquired two derivative instruments that began in November 2021 and ended in March 2022.

​

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 September 30, 2022 and 2021, the Company did held no 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.

​

The weighted average remaining lease term for the Company’s leases is eight years, and the weighted average discount rate for these leases is 3.77%.

​

The operating lease expense recognized in the first nine months of 2022 and 2021 was classified as follows (in millions):

​

​ | ​ | ​ | ​ | ​ | ​ | ​
Classification |  | 2022 |  | 2021

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.

​

On July 20, 2021, the Peruvian Government published Law 31347, which requires companies in the production stage to set aside additional guarantees for progressive closure of its operations. The resources that back these guarantees will be returned to the Company when activities cease and the regulatory agency verifies that all closure measures have been satisfactorily completed. Under this Law, companies must include activities for environmental remediation within the closure schedule and assume costs associated with environmental impacts that are identified during audits. As of June 30, 2022, the regulation attached to this Law had yet to be published. The Company is currently evaluating the possible financial impact of the Law but cannot fully estimate the magnitude until the Law’s regulation is published.

​

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

15

Table of Contents

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 nine 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 nine-month periods ended September 30, 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 nine-month periods ended September 30, 2022 and 2021 were as follows (in millions):

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021
Peruvian operations | ​ | $ | 7.1 | ​ | $ | 2.9
Mexican operations | ​ |  | 35.4 | ​ |  | 57.7
​ | ​ | $ | 42.5 | ​ | $ | 60.6

​

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 September 30, 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.

​

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

17

Table of Contents

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).

​

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

18

Table of Contents

concerns are resolved. Currently, the Company does not expect any impact on its operations. As of September 30, 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.

​

Litigation matters:

​

Peruvian operations:

​

The Tia Maria Mining Project

​

There are six 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 – the judgment ruled in favor of SPCC), 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), Gobierno Regional de Arequipa (filed December 16, 2019) and Municipalidad Distrital de Dean Valdivia (filed in January 2020 but notified in August 2022).

​

The Mendoza Padilla case was initially rejected by the lower court on July 8, 2015. This ruling was confirmed by the Superior Court on June 14, 2016. On July 12, 2016, the case was appealed before the Constitutional Court. On November 20, 2018, the Constitutional Court reversed the previous decisions and remanded the case to the lower court for further action. In the third quarter of 2020, the Company was notified that the complaint had been reinstated. The Company answered the complaint on September 15, 2020. On December 2, 2020, the lower court issued a resolution, considering the complaint answered. On September 27, 2021, the Court ordered to temporarily archive the case.

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 September 30, 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 September 30, 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 September 30, 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 September 30, 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 September 30, 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: 71.7% of the Company's 4,544 Peruvian employees were unionized at September 30, 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 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 $11,749) and S/90,000 (approximately $23,499), depending on the duration of the agreement. A long-term agreement bonus of S/10,000 (approximately $2,611) was granted to the union that signed a six-year extension of the collective bargaining agreement. All these concepts were recorded as labor expense. In 2022, these collective agreements have been executed. The Company does not have any collective agreement pending to be negotiated with the unions. As of September 30, 2022, it is only pending a signing bonus and a salary increase for one union in compliance with an 20218-2019 Arbitration Award.

​

In the first half of 2022, the six unions came together to defend their rights to work in the Cuajone unit. This action was in response to the cut off of water supply and the obstruction of a railroad section carried out by a small group of residents from the community of Tumilaca, Pocata, Coscore and Tala, Moquegua, which directly affected the health and safety of workers and their families and the production process.

​

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.

​

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 September 30, 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.

​

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.

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 tonnes 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. 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 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 has also promoted agricultural and livestock activities in the Tambo Valley and supported growth in manufacturing, fishing and tourism in Islay. In 2021, the Peruvian Branch fortified its relation with the regional government and overcame its opposition to project initiation. This new consensus was reflected in an agreement for Social Investment for Taxes for projects relative to health facilities and roads. The Company´s efforts to

23

Table of Contents

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.

​

During the construction and operation phase, the Company will make it a priority to hire local labor to fill the 9,000 jobs that the Company expects to generate during Tia Maria’s construction phase. Additionally, from day one of its operations, the Company will generate significant contributions to revenues in the Arequipa region.

​

Tia Maria´s project budget is approximately $1.4 billion, of which $333.7 million had been invested as of September 30, 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.

​

As per the purchase agreement, the Company paid $12.5 million at the signing of the contract and $12.5 million in June 2021. The remaining balance of $375.0 million will be paid if the Company decides to develop the project. Therefore, it is not a present obligation. In June 2022, the Company notified the Peruvian authorities the end of the suspension period and the start of the pre-operational period that lasts 12 years and it can be extended for three more years. The start of the pre-operational period does not imply a payment obligation. The Company must support an investment of $20 million in the next five years which includes exploration activities as well as the development of social programs.

​

In 2021, the Company signed social agreements with the Michiquillay and La Encañada communities. In addition, in October 2021, the Peruvian Ministry of Energy and Mines approved the semi-detailed environmental impact study for the project. Currently, the Company has all the required permits for exploration activities. These events will allow Southern Copper to initiate an in-depth exploration program in November of 2022.

​

Social agreements with the Michiquillay and La Encañada communities represent an opportunity to improve quality of life of their residents through the Company´s strong social programs and backed by a solid framework for technical work at the project level. The main commitments signed by the Company in the social agreements are related to providing support for agricultural and livestock activities, financial support for local initiatives, and social programs in favor of education, water management, waste disposal, and healthcare for vulnerable groups.

​

​

Corporate Social Responsibility

​

The Company has a corporate social responsibility policy to maintain and promote the continuity of its mining operations while obtaining 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 $111.7 million). In relation to this commitment, the Company has completed the construction of a school with an investment of S/18.8 million (approximately $4.7 million), has co-financed the construction of the Cularjahuira dam for S/15.6 million (approximately $3.9 million) and is preparing engineering study for the Callazas dam for S/2.6 million (approximately $0.7 million).

24

Table of Contents

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 $30.8 million in its condensed consolidated financial statements as of September 30, 2022.

​

In addition, the Company has committed S/97.7 million (approximately $24.5 million) for the construction of a high-achievement 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. Although the development roundtable is not currently meeting, it was previously discussing the creation of a Moquegua Region Development Fund, for which the Company has offered a contribution of S/1,000 million (approximately $251.0 million). While final funding is not yet settled, the Company has committed to contribute S/108.4 million (approximately $27.2 million) as an advance, which was 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/105.5 million (approximately $24.5 million). There was also a commitment to build three schools in Moquegua for S/18.2 million (approximately $4.6 million) and to build tracks and sidewalks in Pacocha for S/6.4 million (approximately $1.6 million), which have been completed.

​

In addition, the Company has committed S/141.4 million (approximately $35.5 million) to build three 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.

2015 Plan: In January 2015, the Company offered to eligible employees a new stock purchase plan through a trust that acquires series B shares of Grupo Mexico stock for sale to its employees, and employees of subsidiaries, and certain affiliated companies. The purchase price was set at 38.44 Mexican pesos (approximately $2.63) for the initial subscription, which expires in January 2023. Every two years employees will be able to acquire title to 50% of the shares paid in the previous two years. The employees will pay for shares purchased through monthly payroll deductions over the eight year period of the plan. At the end of the eight year period, the Company will grant the participant a bonus of 1 share for every 10 shares purchased by the employee. Any future subscription will be at the average market price at the date of acquisition or the grant date.

​

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

​

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

​

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

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 September 30, 2022 and December 31, 2021 (in millions):

​

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 September 30, 2022 and December 31, 2021 (in millions):

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

​

In addition, in the third quarter of 2021, the Company acquired two derivative instruments to protect natural gas costs from estimated price increases in the previous winter season. These derivative instruments occupied November 2021 through March 2022 period. For further information please refer to Note 6 “Derivative instruments.”

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.

​

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

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

​

The following discussion provides information that management believes is relevant to an assessment and understanding of the condensed consolidated financial condition and results of operations of Southern Copper Corporation and its subsidiaries (collectively, “SCC”, “the Company”, “our”, and “we”). This item should be read in conjunction with our interim unaudited Condensed Consolidated Financial Statements and the notes thereto included in this quarterly report. Additionally, the following discussion and analysis should be read in conjunction with the Management Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements included in Part II of our annual report on Form 10-K for the year ended December 31, 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 third quarter of 2022, approximately 77.8% of our revenue came from the sale of copper; 8.9% from molybdenum; 4.1% from silver; 3.8% from zinc; and 5.4% from various other products, including gold, sulfuric acid, and other materials.

​

● | Copper: In the third quarter of 2022, the LME copper price decreased from an average of $4.25 per pound in the third quarter of 2021 to $3.51 (-17.4%), reflecting concerns about a simultaneous recession in the U.S., Europe and China due to the following factors:

​

| ● | On-going interest rate hikes by the FED, the ECB and other relevant central banks to control inflation.

| ● | A slowdown in the Chinese economy due to Covid-19 restrictions and a weak real estate market.

| ● | The impact of energy prices on consumer´s demand.

​

However, we should note that:

| ● | The most relevant market intelligence houses for the copper market are expecting a market in balance or with a small deficit for 2022. This assumes a growth in demand of about 2.0% in 2022.

| ● | Even though we expect the supply will grow 3.5-4.0% next year, mainly due to new projects (as the Quellaveco one, in Peru), there is uncertainty regarding future production growth in Chile and Peru, which together represent about 40% of the global supply.

| ● | Major warehouses have reported a reduction in copper inventories, which stood at 247,000 tonnes as of September 30. These low inventories represent an extremely low level of consumption.

​

We believe the economic slowdowns in the U.S., China and Europe have temporarily weakened the demand for copper and are driving reductions in current prices. It is important to emphasize that copper plays a leading role in the global shift to clean energy, which correlates positively with our assertion that the underlying demand for copper will be strong in the long-term. In this scenario, we believe the current cycle of low prices should be short-lived.

● | Molybdenum: Represented 9.9% of our sales in the third quarter of 2022 and is currently our most important by-product. Molybdenum prices averaged $16.00 per pound in the third quarter of 2022, compared to $18.43 in the same period of 2021. This represented a 13.2% price decrease.

​

Regarding this by-product, we believe that prices will be supported by lower inventory levels and a market deficit for this year.

​

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 4.1% of our sales in the third quarter of 2022. We believe that the prices for silver will be supported by intensive level of industrial use and the fact that, like gold, it represents value shelter in times of economic uncertainty.

​

● | Zinc: Represented 4.7% of our sales in the third quarter of 2022, with an average price of $1.48 per pound in the quarter, a 8.8% increase from the third quarter or 2021. Zinc is currently our third by-product.

​

● | Production: For 2022, we expect production to reach approximately 900,000 tonnes of copper, which represents a decrease of 3% compared to our 2022 plan. We expect our copper production to bounce back in 2023 and reach 926,100 tonnes of production as we get the Peruvian production back on track and generate new production through our projects at Pilares and Buenavista Zinc Concentrator.

​

We also expect to produce 25,400 tonnes of molybdenum, which represents a decrease of 16.2% over our 2021 production levels. In 2022, we expect to produce 18.9 million ounces of silver, in line with our 2021 production level. Additionally, we expect to produce 63,300 tonnes of zinc from our mines.

​

● | Capital Investments: In the first nine months of 2022, we spent $657.6 million on capital investments; this represented 37.9% of net income and a decrease of 5.4% compared to the amount registered for the same period in 2021. We continue to advance our projects, including the Buenavista Zinc, El Pilar and Pilares projects, which have registered good progress.

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 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 ILLEGAL BLOCKAGE

​

After the Company resumed operations at our Cuajone facilities in April, a plan to gradually scale up production to recover volume losses was implemented. At this point, we estimate that our Peruvian operations will reach 94% of the 2022 production plan of 360,900 tonnes.

​

On October 17, the Peruvian government extended the state of emergency in the Moquegua region for 60 more days.

​

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 including, but not limited to, volatility in commodity prices, cost and supply chain pressures and availability and disruption in capital markets. 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. Although the Company does not currently have operations in Ukraine, Russia or other parts of Europe, this situation is affecting the countries in which we operate and in which our clients and suppliers operate, although the extent of the impact varies.

​

The company has experienced increases in costs as a result of the world crisis and the Russian-Ukrainian war, mainly increments in energy, fuel, explosives and other operating material costs. The increase is due to the higher market share of Russia in these products. The company has taken initiatives searching for alternative suppliers to reduce this effect. As of September 30, 2022, these events impacted our production costs and financial results as it is disclosed in this report. Currently, our sales program has suffered no impacts.

​

Net sales in the third quarter of 2022 were 19.5% lower than in the same period of 2021. This decrease was driven by a drop in average metal prices for copper (-17.4% - LME), molybdenum (-13.2%) and silver (-21.3%) and by a decrease in the sales volumes of molybdenum (-24.2%) and zinc (-11.4%). This effect was slightly offset by higher prices for zinc (+8.8%); and by an increase in the sales volumes of copper (+2.4%) and silver (+8.3%).

​

Net income attributable to SCC in the third quarter of 2022 was 40.2% lower than in the same period of 2021. This decrease was mainly attributable to a drop in average metal prices, a decrease in sales volume of some of our by-products and higher operating costs (+16.8%).

​

Net sales in the first nine months of 2022 were 10.9% lower than in the same period of 2021, due to a decrease in the sales volume of copper (-9.2%), molybdenum (-12.5%) and silver (-4.8%); and to a decrease in average metal prices for copper (-1.2%) and silver (-14.9%). These negative variances were slightly offset by an increase in sales volume of zinc (+2.2%) and by higher average metal prices for molybdenum (+22.5%) and zinc (+26.0%).

​

Net income attributable to SCC in the first nine months of 2022 was 32.3% lower than in the same period of 2021. This decrease was mainly attributable to a decrease in sales and a 16.4% increase in operating costs.

​

Third quarter: Mined copper production in the third quarter of 2022 fell 6.0% to 508.2 million pounds compared to 540.5 million pounds in the third quarter of 2021. This was mainly attributable to a decrease in copper production at our Toquepala (-16.1%), La Caridad (-11.3%) and Cuajone (-6.1%) operations, which was in turn driven by lower ore grades and recoveries. This was slightly offset by an increase of production at our Buenavista (+0.8%) and IMMSA (+13.2%) mines.

​

Molybdenum production decreased 24.8% in the third quarter of 2022 compared to the levels registered in the third quarter of 2021. This was attributable to a decrease in production at our Toquepala (-55.7%), La Caridad (-10.0%) and Buenavista (-6.4%) mines, which was mainly driven by a drop in ore grades and recoveries. This effect was partially offset by an increase in production at our Cuajone (+2.4%) mine due to higher ore grades.

​

Silver mine production increased 0.6% in the third quarter of 2022, compared with the same period of 2021, this was mainly attributable to an increase in production at our Buenavista (+20.2%) mine and at the IMMSA (+0.9%) unit. This was offset by lower production at our Toquepala (18.7%), Cuajone (-10.4%) and La Caridad (-1.9%) mines.

​

Zinc production decreased 11.9% in the third quarter of 2022 compared with the same period in 2021.

This decrease was mainly attributable to a drop in production at the Charcas and Santa Barbara units, which was attributable to a decrease in processed material and lower average zinc grades.

​

Santa Barbara Mine: In a collective action with the authorities of the State of Chihuahua, Mexico, it has been possible to close 42 illegal accesses to the mine, thus preventing the theft of mineral in stone. From September 24 to September 30, the authorities seized seven people during the crime. These acts did not constitute a permanent appropriation of the buildings or surfaces owned by IMMSA nor stop the ordinary course of production.

​

Nine months: Mined copper production in the first nine months of 2022 decreased 9.3% to 1,440.6 million pounds compared to 1,588.8 million pounds in the same period of 2021. This decrease was mainly attributable to the Cuajone mine stoppage (-23.0%) and to a drop in production at our Toquepala (-17.7%) and La Caridad (-14.0%) mines due to lower grades. This effect was slightly offset by an increase in production at Buenavista (+2.1%) and IMMSA (+1.6%) operations.

​

Molybdenum production decreased 12.5% in the first nine months of 2022 compared to the same period in 2021; this was mainly due to lower production at our Cuajone (-21.4%), Toquepala (-21.1%) and La Caridad (-8.2%) mines, which was partially offset by higher production at Buenavista (+3.4%) mine.

​

Silver mine production decreased 5.8% in the first nine months of 2022; this was principally due to lower production at our Toquepala (-23.6%), Cuajone (-22.0%), La Caridad (-6.8%) and IMMSA (-2.0%) operations, which was partially offset by higher production at Buenavista (+9.1%) mine.

​

Zinc production decreased 11.3% in the first nine months of 2022 due to a drop in production at our Charcas, San Martin and Santa Barbara mines, which was principally due to lower grades.

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 58. 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.

​

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.

​

As seen in the table above, our per pound cash cost before by-product revenues in the third quarter of 2022 was 27.2% higher than in the same period of 2021. This increase was mainly attributable to an increase in production costs and the unit cost effect generated by a 6.7% decrease in pounds of copper produced. Our cash cost per pound net of by-product revenue for the third quarter of 2022 increased 77.9% when compared to the same period of 2021. This was mainly due to higher costs of fuel, energy and explosives, lower production explained above and a decrease in all our main by-product revenues except sulfuric acid.

​

For the nine months ended September 30, 2022, our per pound cash cost before by-product revenues was 27.3% higher than in the same period of 2021. This increase was mainly driven by an increase in production costs and the unit cost effect generated by a 9.9% decrease in pounds of copper produced. The operating cash cost per pound of copper net of by product revenue was $0.90 in the nine months ended September 30, 2022. This represented an increase of 41.1% compared to the $0.64 reported in the same period of 2021. These results were mainly due to higher production costs and the unit cost effect generated by a 9.9% decrease in pounds of copper produced partially offset by an increase of 18% in by-product revenue.

​

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 three 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:

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 $657.6 million in the nine months ended September 30, 2022, compared to $695.5 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. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy and market conditions.

​

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. All the main equipment is on site and construction site works are in progress. The project has all the necessary permits and the capital budget is $413 million. When completed, this new facility will double the Company’s zinc production capacity and will provide 490 direct jobs and 1,470 indirect jobs. We expect to initiate operations in the second half of 2023. As of September 30, 2022, we have invested $292.4 million in this project, where physical completion is at 83%.

​

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 0.29% from La Caridad). The budget for Pilares is $159 million. As of September 30, 2022, the project was 95% complete and has obtained all permits and licenses required. Pilares has initiated operations and is currently mining copper oxides and mineral to be processed.

​

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. The budget for El Pilar is $310 million. We expect this project to start production in 2024 with an expected mine life of 13 years. The results from

experimental pads in leaching process have confirmed adequate levels of copper recovery. The basic engineering study is finished and the Company continues developing the project and engage in onsite environmental activities. The SX-EW plant EPCM project has been awarded to a contractor and has started.

​

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 $65.5 million, of which we have invested $57.7 million as of September 30, 2022. The furnace of the plant started operations in the second quarter, complying with the performance tests.

​

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 September 30, 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 $155.4 million as of September 30, 2022.

​

Tia Maria - Arequipa: This greenfield project, located in Arequipa, Peru, will use state of the art SX-EW technology with the highest international environmental standards to produce 120,000 tonnes of SX- EW copper cathodes per year. The estimated capital budget for the project is $1.4 billion.

​

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 have also promoted agricultural and livestock activities in the Tambo Valley and supported growth in manufacturing, fishing and tourism in Islay.

​

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. Given the current Peruvian economic situation, it is crucial to move ahead on projects that will stimulate a sustainable growth cycle. We will make it a priority to hire local labor to fill the 9,000 jobs that we expect to generate during Tia Maria’s construction phase. Additionally, from day one of our operations, we will generate significant contributions to revenues in the Arequipa region.

​

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 and market conditions.

​

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 average 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. The Company has completed the environmental impact assessment, which will be filed with the authorities shortly.

​

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%. The 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 2022, we continued to engage in social and environmental improvements for the local communities and worked on the project´s environmental impact assessment.

In February 2022, a group of illegal miners occupied a portion of the project’s lands and began to produce copper through a small-scale artisanal process. On May 31, 2022, a group of people attacked the project mining camp causing a fire, which completely destroyed the installations. As of September 30, 2022 part of the project´s land continued to be occupied by illegal miners, some of whom have irregularly registered their stakes in the "Integral Registry of Mining Formalization" (REINFO). The Company has filed criminal complaints and other legal remedies, which have annulled the claims of 43 illegal miners while 32 cases remain open.

​

Michiquillay Project - Cajamarca: In June 2018, Southern Copper signed a contract for the acquisition of the Michiquillay project in Cajamarca, Peru. 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 and at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2029. Michiquillay will become one of Peru´s largest copper mines and will create significant business opportunities in the Cajamarca region; generate new jobs for the local communities; and contribute taxes and royalties to the local, regional and national governments.

​

In 2021, the Company signed Social Agreements with the Michiquillay and the Encañada Communities. In addition, on October 1, 2021, the Peruvian Ministry of Energy and Mines approved the semi-detailed Environmental Impact Study for the project. These events will allow Southern Copper to initiate an in-depth exploration program in November 2022.

​

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

​

​

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (“ESG”)

​

At Southern Copper, we have strengthened governance relative to sustainable development. The Sustainable Development Committee, which is presided by an independent member of the board, held its first session on October 14, 2022. During this encounter, our counselors reviewed our advances in terms of our main performance indicators and gave us recommendations for the climate change strategy we are building.

​

We adhered to the United Nations (UN) Global Compact. Through the affiliation of AMC, our holding corporation,we reaffirm our commitment to align our policies, strategies, and operations with the Ten Principles of the Global Compact, addressing such issues as human rights, labor rights, the environment and anti-corruption. Our adherence of the Global Compact will also position us to further our contributions to the 2030 Agenda for Sustainable Development Goals and the Paris Agreement.

​

Regarding climate change, we are actively collaborating with the International Copper Association (ICA) to define the Global Copper Decarbonization Roadmap, which is aligned with the Paris Agreement. The results of these efforts have nurtured our medium and long-term objectives and will be published in the first quarter of 2023.

​

Since ,occupational safety is a priority for the Company, the Mexican Government awarded our Caridad metallurgical operation, located in Sonora, Mexico, the distinction of “Safe and Healthy Workplace.” The Company was recognized for its voluntary program to implement strategies and actions to improve the safety, health and wellbeing of our workers while bolstering the productivity and quality of the workplace. The precious metals plant, which is part of the aforementioned complex, received the Casco de Plata (Silver Helmet) in the category “Smelters with less than 500 workers,” which was awarded by the Mining Chamber of Mexico in recognition of the fact that the plant was the best performer on the occupational accident index for 2021.

​

A reduction in accident rates and a renewed drive to safeguard the health and safety of our workers led MAPFRE-Peru to award our Toquepala unit with the “Safety Excellence Award” in 2021. This distinction recognizes the effectiveness of the Comprehensive System for Occupational Safety and Health Management that has been implemented at this mine and throughout the organization.

Thanks to our commitment to adequately use and preserve water resources, we have begun building a wastewater treatment plant in Ilo, Moquegua, Peru. This project will require an investment of $27 million and will benefit more than 77,000 people. SCC will operate and maintain this plant for the next 30 years to prevent wastewater from being discharged into the ocean, which will protect the marine ecosystem and public health. The President of the Council of Ministers, Anibal Torres, inaugurated this facility by, remarking that the “mining sector plays a fundamental role in the country’s growth and that the synergy between the State and the private sector is fueling the construction of emblematic projects.” Prime minister Torres was accompanied by the Minister of Energy and Mines and the Minister of Housing, Construction and Sanitation at this event.

​

Regarding social impact, in the framework of the 14º International Mining Congress, which was held in Hermosillo, Sonora, Mexico, the Association of Mining Engineers, Metallurgists and Geologists of Mexico (Asociacion de Ingenieros de Minas, Metalurgistas y Geologos de México A.C.) bestowed on Grupo Mexico, the holding company of AMC, with an Award, in recognition of the corporation’s efforts to generate more social impact in this state of Mexico.

​

More than 300 outstanding students will benefit from the construction of modern infrastructure for the High-Performance School of Moquegua (Colegio de Alto Rendimiento de Moquegua−COAR), which SCC will build through the Taxes for Works mechanism, in conjunction with the Ministry of Education (MINEDU). The project’s first stone was laid at a well-attended ceremony. The facility will be completed over a period of 18 months and will require an investment of $25 million. During the ceremony, the Minister of Education, Rosendo Serna, praised the Company’s contribution to education: “We believe in investing in education and take the struggle against the deep deficit of education infrastructure that seriously affects our country. This task is enormous and lenghty. Therefore, we thank Southern Peru for joining the fight to improve the educational conditions of millions of children and young people throughout the country.”

​

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.

​

NET SALES

​

Net sales in the third quarter of 2022 were 19.5% lower than in the same period of 2021. This decrease was driven by a drop in average metal prices for copper (-17.4% - LME), molybdenum (-13.2%) and silver (-21.3%) and by a decrease in the sales volumes of molybdenum (-24.2%) and zinc (-11.4%). This effect was slightly offset by higher prices for zinc (+8.8%); and by an uptick in sales volumes of silver (+8.3%) and copper (+2.4%).

​

Net sales in the first nine months of 2022 were 10.9% lower than in the same period of 2021, due to a decrease in the sales volume of copper (-9.2%), molybdenum (-12.5%) and silver (-4.8%); and to a decrease in average metal prices of copper (-1.2%), and silver (-14.9%). These negative variances were slightly offset by an increase in sales volume of zinc (+2.2%); as well as by higher average metal prices for molybdenum (+22.5%) and zinc (+26.0%).

NON-OPERATING INCOME (EXPENSES)

​

Non-operating income (expense) represented a net expense of $37.7 million and $186.1 million in the three and nine months that ended on September 30, 2022, compared to a net expense of $89.3 million and $270.4 million in the three and nine months ended September 30, 2021.

​

Third quarter: The $51.6 million decrease in the expense level was principally due to:

​

● | $40.7 million increase in other income, net, mainly due to $28.5 adjustment of excess in provision of freights and other purchases costs, $3.7 million of lower rain damage and social responsibility expenses and $8.5 million of lower miscellaneous expenses,

● | $6.3 million increase in interest income, partially offset by

● | $0.1 million increase in interest expense, and

● | $4.6 million increase in capitalized interest.

​

Nine months: The $84.3 million decrease in the expense level was principally due to:

​

● | $62.2 million increase in other income, net which includes $28.5 million adjustment of excess in provision of freights and other purchases costs, $20.3 million of insurance recovery from Carla Lacey case and $11.3 million of lower rain damage expenses in Peru.

​

Net sales in the third quarter of 2022 were $815.7 million compared to $1,122.8 million in the third quarter of 2021. The decrease in net sales was mainly driven by a drop in prices for copper (-17.4%), molybdenum (-13.2%) and silver (-21.3%); and by a decrease in the sales volumes of copper (-14.5%), molybdenum (-40.9%) and silver (-26.3%). The decrease in molybdenum sales is mainly explained by a reduction in production due to lower grades.

​

Operating costs and expenses in the third quarter of 2022 increased by $91.1 million to $592.1 million compared to $501.0 million in the same period of 2021. This was primarily due to:

​

​ | ​ | ​ | ​ | ​ | ​
​ | Operating cost and expenses for the third quarter of 2021 |  | $ | 501.0
​ | Plus: | ​ | ​ |  |
​ | • | Increase in other cost of sales (exclusive of depreciation, amortization and depletion), which was mainly attributable to increases in fuel costs, inventory consumption, operating contractors and foreign currency effects; this was partially offset by a decrease in labor costs and lower workers' participation. | ​ | ​ | 138.4

​ | Operating cost and expenses for the third quarter of 2022 | ​ | $ | 592.1

​

Net sales in the first nine months of 2022 were $2,821.4 million compared to $3,220.9 million in the same period of 2021. The decrease in net sales was mainly driven by lower sales volumes of copper (-11.4%), silver (-18.6%) and molybdenum (-21.6%) and by a decrease in the average metal prices of copper (-1.2%) and silver (-14.9%). This effect was slightly offset by an increase in average metal prices of molybdenum (+22.5%) prices.

​

Operating costs and expenses in the first nine months of 2022 increased by $350.3 million to $1,838.7 million compared to $1,488.4 million in the same period of 2021. This was primarily due to:

​

​

Net sales in the third quarter of 2022 were $159.2 million, compared to $175.1 million in the same period of 2021. This decrease of $15.9 million was primarily due to the decrease in sales volumes of zinc (-11.4%) and copper (-7.9%); and by lower average metal prices for copper (-17.4%) and silver (-21.3%). This effect was slightly offset by an increase in sales volumes of silver (+8.0%) and higher zinc (+8.8%) prices.

​

Operating costs and expenses in the third quarter of 2022 increased by $7.5 million and reached $160.6 million versus $153.1 million in the same period of 2021. This was primarily due to:

Significant items added to (deducted from) net income to arrive at operating cash flow include depreciation, amortization and depletion, deferred tax amounts, foreign currency fluctuations and changes in operating assets and liabilities.

​

Nine months ended September 30, 2022: Net income was $1,742.9 million, which represented approximately 101.3% of the net operating cash flow. Operating cash flow decreased by $781.6 million due to the following variances in operating assets and liabilities:

​

● | $292.9 million decrease in trade accounts receivable, primarily driven by higher collections at our Peruvian and Mexican operations.

● | $(768.6) million decrease in accounts payable and accrued liabilities, which was mainly driven by a decrease in accrued income taxes at our Mexican and Peruvian operations.

● | $(248.0) million increase in other operating assets and liabilities, net, principally due to an increase in other accounts receivables at our Mexican operations mainly to workers.

● | $(57.9) million net increase in inventory; this was primarily driven by a $36.0 million increase in the work in process inventory, principally at our Mexican operations.

​

Nine months ended September 30, 2021: Net income was $2,574.8 million, which represented approximately 84.0% of the net operating cash flow.

​

Changes in operating assets and liabilities increased cash flow by $30.0 million due to the following variances:

● | $(424.5) million increase in trade accounts receivable, which was mainly attributable to the increase in metal prices in 2021.

● | $(8.3) million net increase in inventory; this was primarily driven by a $29.2 million increase in the work in process inventory, which was in turn partially offset by a $21.4 million drop in the work in process inventory.

● | $409.5 million increase in accounts payable and accrued liabilities, which was mainly due to the increase in accrued income taxes and workers’ participation at our Mexican and Peruvian operations.

● | $53.3 million decrease in other operating assets and liabilities.

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 September 30, 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 and six months ended September 30, 2022 and 2021:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Three Months Ended |  |  | Nine Months Ended |
​ | ​ | September 30, | ​ | ​ | September 30, | ​
​ |  | 2022 |  | 2021 |  |  | 2022 |  | 2021 |
Peru: |  |  |  |  |  |  |  |  |  |
Peruvian inflation rate |  | 2.1 | % | 2.4 | % |  | 6.7 | % | 4.6 | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Initial exchange rate |  | 3.830 |  | 3.866 |  |  | 3.998 |  | 3.624 |
Closing exchange rate |  | 3.984 |  | 4.136 |  |  | 3.984 |  | 4.136 |
Appreciation/(devaluation) |  | (4.0) | % | (7.0) | % |  | 0.4 | % | (14.1) | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Mexico: |  |  |  |  |  |  |  |  |  |
Mexican inflation rate |  | 2.1 | % | 1.4 | % |  | 6.2 | % | 4.9 | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Initial exchange rate |  | 19.985 |  | 19.803 |  |  | 20.584 |  | 19.949 |
Closing exchange rate |  | 20.306 |  | 20.306 |  |  | 20.306 |  | 20.306 |
Appreciation/(devaluation) |  | (1.6) | % | (2.5) | % |  | 1.4 | % | (1.8) | %

​

Change in monetary position:

​

Assuming an exchange rate variance of 10% at September 30, 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 | ​ | $ | 7.5
Devaluation of 10% in U.S. dollar vs. Peruvian sol | ​ | $ | (9.1)
Appreciation of 10% in U.S. dollar vs. Mexican peso | ​ | $ | (42.3)
Devaluation of 10% in U.S. dollar vs. Mexican peso | ​ | $ | 51.7

​

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 September 30, 2022.

​

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.

​

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 September 30, 2022 and 2021, we did held no 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 September 30, 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 September 30, 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 September 30, 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 September 30, 2022, the related condensed consolidated statements of earnings, comprehensive income and cash flows for the three-month and nine-month periods ended September 30, 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 consolidated 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 2022, the political action of certain groups in Peru has prompted violence in the demands of certain communities, which affected Cuajone's operations. In February 2022, the railway between Cuajone and Ilo was blocked and the facilities at the Vina Blanca water reservoir were seized, cutting off the water supply to some residents of the Cuajone mining camp.

​

After several unsuccessful attempts by the authorities to restore order through dialogue efforts, in April 2022, the Peruvian government declared a state of emergency in the Moquegua region and the protesters returned the installations of the Vina 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-dialogue-table with members of the community, government and Company officials to better understand all parties’ concerns. As of today, ten round-table meetings and two direct meetings with the community have been held. The Company has proposed plans to invest in social programs that address the needs voiced by the communities and has indicated interest in purchasing land near the Cuajone operations to establish a buffer zone to protect installations and production down the line.

​

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

​

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 September 30, 2022 was $44.84 and the maximum number of shares that the Company could purchase at that price was 1.8 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 September 30, 2022. There has not been any activity in the SCC share repurchase program since the third quarter of 2016.
