EXPLANATORY NOTEPART I

ITEM 1. BUSINESS

On February 28, 2020,

THE COMPANY

We believe Southern Copper Corporation (“SCC,” “us,” “our,”SCC”, “Southern Copper” or the “Company”) is one of the largest integrated copper producers in the world. Our major production includes copper, molybdenum, zinc and silver. All of our mining, smelting and refining facilities are located in Peru and Mexico and we conduct exploration activities in those countries and in Argentina, Chile and Ecuador. See Item 2 “Properties—Review of Operations” for maps of our principal mines, smelting facilities and refineries. The considerable scale of our operations makes us one of the largest mining companies in Peru and Mexico. We believe we have the largest copper reserves in the world. We were incorporated in Delaware in 1952 and have conducted copper mining operations since 1960. Since 1996, our common stock has been listed on both the New York and Lima Stock Exchanges.

Our Peruvian copper operations involve mining, milling and flotation of copper ore to produce copper concentrates and molybdenum concentrates; the smelting of copper concentrates to produce blister and anode copper; and the refining of anode copper to produce copper cathodes. As part of this production process, we also produce significant amounts of molybdenum concentrate and sulfuric acid. Our precious metals plant at the Ilo refinery produces refined silver, gold, and other materials. Additionally, we produce refined copper using solvent extraction/electrowinning technology (“SX-EW”). We operate the Toquepala and Cuajone open-pit mines high in the Andes Mountains, approximately 860 kilometers southeast of the city of Lima, Peru. We also operate a smelter and refinery west of the Toquepala and Cuajone mines in the coastal city of Ilo, Peru.

Our Mexican operations are conducted through our subsidiary, Minera Mexico, S.A. de C.V. (“Minera Mexico”), which we acquired in 2005. Minera Mexico engages primarily in the mining and processing of copper, molybdenum, zinc, silver, gold and lead. Minera Mexico operates through subsidiaries that are grouped into three separate units. Mexicana de Cobre, S.A. de C.V. (together with its subsidiaries, the “La Caridad” unit) operates La Caridad, an open-pit copper mine, a copper ore concentrator, a SX-EW plant, a smelter, refinery and a rod plant. The La Caridad refinery has a precious metals plant that produces refined silver, gold and other materials. Operadora de Minas e Instalaciones Mineras, S.A de C.V. (the “Buenavista unit”) operates Buenavista, an open-pit copper mine, which is located on the site of one of the world’s largest copper ore deposits, two copper concentrators and two operating SX-EW plants. Industrial Minera Mexico, S.A. de C.V. (together with its subsidiaries, the “IMMSA unit”) operates five underground mines that produce zinc, lead, copper, silver and gold, and a zinc refinery.

We utilize modern, state of the art mining and processing methods, including global positioning systems and computerized mining processes. Our operations have a high level of vertical integration, which allows us to use our facilities, employees and equipment to manage the entire production process, including ore mining and production of refined copper rod and other products, and to execute most associated transport and logistics functions.

The sales prices for our products are largely determined by market forces beyond our control. Our management, therefore, focuses on cost control and production enhancement to remain profitable. We endeavor to achieve these goals through capital spending programs, exploration efforts and cost reduction programs. Our focus is on remaining profitable during periods of low copper prices and maximizing results in periods of high copper prices. For additional information on the sale prices of the metals we produce, please see “Metal Prices” in this Item 1.

Currency Information:

Unless stated otherwise, all our financial information is presented in U.S. dollars and any reference herein to “U.S. dollars,” “dollars,” or “$” are to U.S. dollars; references to “sol,” “soles” or “S/”, signify Peruvian soles; and references to “peso,” “pesos,” or “Ps.,” represent Mexican pesos.

ORGANIZATIONAL STRUCTURE

The following chart describes our organizational structure, starting with our controlling stockholders, as of December 31, 2020. For clarity purposes, the chart identifies only our main subsidiaries and eliminates intermediate holding companies.

Graphic

We are a majority-owned, indirect subsidiary of Grupo Mexico S.A.B. de C.V. (“Grupo Mexico”). As of December 31, 2020, Grupo Mexico, through its wholly-owned subsidiary Americas Mining Corporation (“AMC”), owned 88.9% of our capital stock. Grupo Mexico’s principal business is to act as a holding company for the shares of other corporations engaged in the mining, processing, purchase and sale of minerals and other products and in the provision of railway and other related services.

We conduct our operations in Peru through a registered branch (the “SPCC Peru Branch”, “Branch” or “Peruvian Branch”). The SPCC Peru Branch comprises virtually all of our assets and liabilities associated with our copper operations in Peru. The SPCC Peru Branch does not constitute a corporation that is separate from SCC, and, as such, the obligations of the SPCC Peru Branch are direct obligations of SCC and vice-versa. The SPCC Peru Branch is, however, registered as a branch of a foreign company pursuant to Peruvian law and through this entity, we hold assets, incur liabilities and conduct operations in Peru. Although the SPCC Peru Branch has no capital or liability that is separate from that held or applicable to SCC, the SPCC Peru Branch is deemed to have equity capital for purposes of determining the economic interests of holders of our investment shares (See Note 14 “Stockholders´ Equity” of the consolidated financial statements).

In April 2005, we acquired Minera Mexico, from Americas Mining Corporation (“AMC”), a subsidiary of Grupo Mexico, our controlling stockholder. Minera Mexico is a holding company and all of its operations are conducted through subsidiaries that are grouped into three units: (i) the La Caridad unit (ii) the Buenavista unit and (iii) the IMMSA unit. We own 99.96% of Minera Mexico.

In 2008, our Board of Directors (“BOD”) authorized a $500 million share repurchase program that has since been increased by the BOD and is currently authorized to $3 billion. Pursuant to this program, through December 31, 2020 we have purchased 119.5 million shares of our common stock at a cost of $2.9 billion. These shares are available for general corporate purposes. We may purchase additional shares 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.

REPUBLIC OF PERU AND MEXICO

Our revenues are derived primarily from our operations in Peru and Mexico. Risks related to our operations in both countries include those associated with economic and political conditions, the effects of currency fluctuations and inflation, the effects of government regulations and the geographic concentration of our operations.

Actual results could differ materially depending upon certain 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, the 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, which can be volatile.

Additional business information follows:

COPPER BUSINESS

Copper is an important component in the world’s infrastructure chain. It is the third most widely used metal, after iron and aluminum. Copper has unique chemical and physical properties, including high ductility; malleability; thermal and electrical conductivity; and resistance to corrosion, and as such, is considered a prime material for use in electrical and electronic products, including components for power transmission and generation, which accounts for about three quarters of copper global use, and for telecommunications, building construction, transportation and industrial machinery. Copper is also an important metal in non-electrical applications such as plumbing and roofing and, when alloyed with zinc to form brass, is used in many industrial and consumer applications.

Table of Contents

Copper is an internationally traded commodity whose prices are mainly determined by the major metal exchanges, the Commodities Exchange, or “COMEX,” in New York and the London Metal Exchange or “LME,” in London. Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced in a multi-stage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasingly larger share of copper is being produced from acid leaching of oxidized ores. Copper is one of the oldest metals known to man and has contributed significantly to the development of civilization.

BUSINESS REPORTING SEGMENTS:

Our management divides Southern Copper into three reportable segments and manages each as a separate segment.

The three segments identified are groups of individual mines, each of which constitutes an operating segment with similar economic characteristics, product types, processes and support facilities, regulatory environments, employee bargaining contracts and 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.

Inter-segment sales are based on arm’s length prices at the time of sale. These may not be reflective of actual prices realized by the Company due to various factors, including additional processing, timing of sales to outside customers and transportation cost. Information regarding the Company’s sales is included in the segment data. The segments identified by the Company are:

1.Peruvian operations, which include the Toquepala and Cuajone mine complexes and the smelting and refining plants, including a precious metals plant, industrial railroad and port facilities that service both mines. Sales of its products are recorded as revenue from our Peruvian mines. The Peruvian operations produce copper, by-products of molybdenum, silver and other materials.

2.Mexican open-pit operations, which include the La Caridad and Buenavista mine complexes and the smelting and refining plants, including a precious metals plant and a copper rod plant and support facilities that service both mines. Sales of its products are recorded as revenue of our Mexican mines. The Mexican open-pit operations produce copper, with production of by-products of molybdenum, silver and other materials.

3.Mexican underground mining operations, which include five underground mines that produce zinc, copper, lead, silver and gold; and a zinc refinery. This group is identified as the IMMSA unit and sales of its products are recorded as revenue from the IMMSA unit.

Financial information is periodically prepared for each of the three segments and the results are reported to the Chief Operating Decision Maker (“CODM”) on a segment basis. The CODM 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.

Segment information is included in Item 2 “Properties,” under the captions—“Metal Production by Segments” and “Ore Reserves.” More information on business segment and segment financial information is included in Note 18 “Segment and Related Information” of the consolidated financial statements.

CAPITAL INVESTMENT PROGRAM AND EXPLORATION ACTIVITIES

PRINCIPAL PRODUCTS AND MARKETS

Copper is primarily used in the building and construction industries; in the power generation and transmission industry; and in the electrical and electronic products; and, to a lesser extent, in industrial machinery and equipment; consumer products; and in the automotive and transportation industries. Molybdenum is used to toughen alloy steels and soften tungsten alloy and is also used in fertilizers, dyes, enamels and reagents. Silver is used for photographic, electrical and electronic products and, to a lesser extent, in brazing alloys and solder, jewelry, coinage, silverware and catalysts. Zinc is primarily used as a coating on iron and steel to protect against corrosion; it is also used to make die cast parts to manufacture batteries and to form sheets for architectural purposes.

Our marketing strategy and annual sales planning emphasize developing and maintaining long-term customer relationships. As such, acquiring annual or other long-term contracts for the sale of our products is a high priority. Generally, 80% to 90% of our metal production is sold under annual or longer-term contracts. Sales prices are determined based on the prevailing commodity prices for the quotation period according to the terms of the contract.

We focus on end-user customers as opposed to selling on the spot market or to trading companies. In addition, we devote significant marketing efforts to diversifying our sales both by region and customer base. We also strive to provide superior customer service, including timely deliveries of our products. Our ability to consistently fulfill customer demand is underpinned by our substantial production capacity.

For additional information on sales please see “Revenue recognition” in Note 2 “Summary of Significant Accounting Policies” and Note 18 “Segment and Related Information” of the consolidated financial statements.

METALS PRICES

Prices for our products are principally a function of supply and demand and, with the exception of molybdenum, are established on COMEX and LME. Prices for our molybdenum products are established by reference to the publication Platt’s Metals Week. Our contract prices also reflect any negotiated premiums and the costs of freight and other factors. From time to time, we have entered into hedging transactions to provide partial protection against future decreases in the market price of metals and we may do so under certain market conditions. For a further discussion of our products market prices, please see Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Metal Prices.”

COMPETITIVE CONDITIONS

Competition in the copper market is based primarily on price and service basis, with price being the most important factor when supplies of copper are ample. Our products compete with other materials, including aluminum and plastics. For additional information, see Item 1A “Risk Factors—The copper mining industry is highly competitive.”

HUMAN CAPITAL RESOURCES

As of December 31, 2020, we had 13,777 employees, approximately 71% of whom are unionized and represented by nine different labor unions. We believe that the labor environment in our operations in Mexico and Peru is favorable, which has allowed us to increase productivity as we advance the goals of our capital expansion program.

As a large integrated copper producer, we have a wide range of employees, including management professionals, technicians, engineers, and production employees.  In Peru and Mexico we provide a wide variety of opportunities for professional growth for all employees with trainings and on-the-job experience. As of December 31, 2020, approximately 6.5% of our total workforce was female.

The Company seeks to create value for its employees to ensure that their working experience is optimal. Various efforts are made on this front, including promoting a safe and collaborative work environment and culture and ensuring employees continue to be engaged with the Company’s values and principles. We believe that this generates the bases for shared values and improves our employer brand for existing and future employees. We also focus on attracting and retaining employees by providing compensation and benefit packages that are competitive within the applicable market, taking into account the location of the position, responsibilities and compensation requirements in the countries where we operate. Our compensation practices consider many factors, including individual performance and responsibilities; years of service; elements of compensation mandated by Peruvian and Mexican law; future challenges and objectives; contributions to the future success of our Company; the employee’s total compensation and our financial performance. We may also look at the compensation levels of comparable companies.

In 2020, in response to COVID-19, we incurred $27.6 million in COVID-19 related production costs, which included protective equipment and labor costs to support employees where operations were impacted; expanding, where possible, options for remote work; and enhancing safety protocols. For additional information, refer to Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations and Note 1 “Description of the Business, COVID-19 Pandemic” to the consolidated financial statements.

In terms of corporate culture, the Company is committed to the continuous growth and development of its employees and surrounding communities. Through values such as creativity, honesty, equality and respect, we ensure that our employees are aligned with the same principles and work ethics, which in turn results in a standardized culture across the Company. The Company also seeks to promote goal-oriented principles to obtain results that positively affect our main stakeholders and communities and which focus on innovation, human growth and wellbeing, environmental care, and forward thinking.

We deploy several talent attraction programs, which entail leveraging organizational relations; establishing links with national and regional institutions of higher learning in the countries where we operate; and participating in job fairs. We also have a careers page and use several local and international job boards to publish openings.

We offer professional internship programs to attract students before they graduate from universities or centers for vocational training. Additionally, we believe that we are a first-choice employer in the countries where we operate. This reflects our efforts to strengthen relationships with our stakeholders, including employees, and engage in community development. We have transparent selection processes and are committed to upholding principles for Human Rights and Diversity, Inclusion and Non-Discrimination.

All our employees receive initial training and opportunities for continuous development throughout their careers, which favors talent retention. We also prioritize recruiting from our ranks and 60% of our vacant positions, on average, are filled by current employees looking to make career moves.

Voluntary turnover indicators in all of the countries in which we operate remain at single digits year-over-year. We believe that this is proof that our employees have a strong desire to continue working with us.

In addition, we conduct a biannual Employee Opinion Survey to measure employees’ perceptions of the Company to take actions that will increase employee engagement. We have decided to measure the factors that affect our organizational climate, which entails assessing how people perceive of the environment inside the organization, and how internal and/or external factors generate impact, and focuses on culture, which reflects the aggregate of behaviors, experiences, habits, practices, values, procedures and policies inside the organization.

All employees, both unionized and non-unionized, are invited to participate in all of our human talent initiatives. This reflects our belief that it is in the Company’s best interest to listen to all of our people and create an open communications channel. We apply surveys every two years and approximately 70% of our employees participate. This number far exceeds that registered by other companies that apply similar surveys.

We measure the employee engagement level with 18 sub-factors, which are grouped into two major sets of factors: loyalty and satisfaction. The first factor represents the degree to which an individual identifies with the organization and its business goals, whereas the second reflects the individual’s degree of satisfaction with his/her working conditions and draws a line between satisfaction levels and performance at work.

The average of these factors indicates the level of engagement on a scale of 1 to 5 (a Likert scale). In 2017, we had an engagement rating of 3.71 and in 2019, our rating was situated at 3.77. This represents a 1.6% improvement from 2017 to 2019.

We have adopted a corporate social responsibility policy that is designed to integrate the Company´s operations with local communities in areas influenced by our operations. This policy focuses on creating permanent and positive relationships to generate optimal social conditions and promote sustainable development in the area. We continue to make significant expenditures for community programs.  For additional information on our community programs, refer to Corporate Social Responsibility under Note 13 “Commitments and contingencies” to the consolidated financial statements.

Peru

66% of the Company’s 4,739 Peruvian employees were unionized as of December 31, 2020. Currently, there are six separate unions, one large union and five small unions. In June 2018, the Company signed a three-year collective bargaining agreement with one of the smaller unions. This agreement includes, among other things, annual salary increases of 5% for each year starting September 2018, and a signing bonus of S/45,000 (approximately $13,600) which was recorded as labor expense. In August 2018, the Company signed a three-year collective bargaining agreement with three additional unions. This agreement includes, among other things, annual salary increases of 5% for each year starting December 2018, and a signing bonus of S/45,000 (approximately $13,600) which was recorded as labor expense. In March 2019, the Company resolved pending issues through arbitration with one additional union. The arbitral award included annual salary increases of 5% for each year starting September 2018 and a signing bonus of S/45,000 (approximately $13,600), which was recorded as a labor expense in the first quarter of 2019.

In May 2019, arbitration resolved pending issues with the remaining union. The arbitral award included a salary increase of 5.5% beginning in September 2018 and a bonus of S/16,000 (approximately $4,800) for the one-year agreement, which was recorded as a labor expense in the second quarter of 2019. In November 2019, the Company signed a collective bargaining agreement for three years with the same union. This agreement included, among other things, a salary increase of 5% for each year starting in September 2019 and a bonus of S/45,000 (approximately $13,300), which was recorded as labor expenses in the fourth quarter of 2019.

Employees of the Toquepala and Cuajone units reside in townsites, where we have built 3,700 houses and apartments. We also have 90 houses in Ilo for staff personnel. Housing, together with maintenance and utility services, is provided at minimal cost to most of our employees. Our townsite and housing complexes include schools, medical facilities, churches, social clubs and recreational facilities. We also provide shopping, banking and other services at the townsites.

Mexico

74% of our 8,962 Mexican employees were unionized as of December 31, 2020 and are represented by three separate unions. Under Mexican law, the terms of employment for unionized workers are set forth in collective bargaining agreements. Mexican companies negotiate the salary provisions of collective bargaining agreements with the labor unions on an annual basis and negotiate other benefits every two years. We conduct negotiations separately at each mining complex and each processing plant.

Our Taxco mine in Mexico has been on strike since July 2007. For a discussion of labor matters, refer to the information contained under the caption “Labor matters” in Note 13 “Commitments and Contingencies” of the consolidated financial statements.

Employees of La Caridad and Buenavista units reside in townsites at Nacozari and Cananea, where we have built approximately 1,800 houses and apartments. Most of the employees of the IMMSA unit reside on the grounds of the mining or processing complexes where they work. We have built 356 houses and apartments on these sites. Housing, together with maintenance and utility services, is provided at minimal cost to most of our employees. Our townsites and housing complexes include educational and medical facilities, churches, social clubs, shopping centers, banking and other services. Through 2007, the Buenavista unit provided health care services to employees and retired unionized employees and their families through its own on-site hospital. In 2010, the Company signed an agreement with the Secretary of Health of the State of Sonora to provide these services to its retired workers and their families. The new workers of Buenavista receive health services through the Mexican Institute of Social Security as is the case for all Mexican workers.

FUEL, ELECTRICITY AND WATER SUPPLIES

The principal raw materials used in our operations are fuel, gas, electricity and water. We use natural gas to power boilers as well as generators and for metallurgical processes at our Mexican operations and utilize diesel fuel to power mining equipment. We believe that sufficient sources of fuel, electricity and water are readily available. Fluctuations

10

Table of Contents

may occur in the prices of these raw materials that are beyond our control; as such, we focus our efforts on reducing costs through cost and energy-saving measures.

Energy generates the main cost in mining, so concern for its conservation and efficient usage is critical. We have energy management committees at most of our mines, which meet periodically to discuss consumption and to develop measures directed at saving energy. Also, alternative sources are being analyzed at the corporate level, including both traditional and renewable energy sources. This approach has helped us to develop a culture of energy conservation directed at ensuring the sustainability of our operations.

Peru:

Fuel: In Peru, we obtain fuel primarily from local companies. The Company believes that adequate supplies of fuel are available in Peru.

Electricity: In June 2014, we entered into a power purchase agreement for 120 megawatt (“MW”) with the state company Electroperu S.A., which began supplying energy to our Peruvian operations for a twenty-year period that started on April 17, 2017. In July 2014, we entered into a power purchase agreement for 120MW with a private power generator Kallpa Generacion S.A. (“Kallpa”), which began supplying energy to our Peruvian operations for a ten-year period that started on April 17, 2017. In May 2016, we signed an additional power purchase agreement for a maximum of 80MW with Kallpa, under which Kallpa will supply energy to the operations related to the Toquepala expansion and to other minor projects for a period starting on May 1, 2017 and ending after ten years of commercial operations at the Toquepala Expansion or until April 30, 2029; whichever occurs first. We feel confident that additional power can be obtained from the Peruvian national grid, should the need arise.

Additionally, we have nine megawatts of power generation capacity from two small hydro-generating installations at Cuajone. Power is distributed over a 224-kilometer closed loop transmission circuit, which is connected to the Peruvian network.

Water: We have water rights or licenses for up to 1,950 liters per second from well fields at the Huaitire, Vizcachas and Titijones aquifers and surface water rights from Lake Suches and two small water sources, Quebrada Honda and Quebrada Tacalaya. We believe these water sources are sufficient to supply the needs of our operating units at Toquepala and Cuajone, including the Toquepala expansion. In Ilo, we have two desalination plants that produce water for industrial use and domestic consumption that we believe will produce sufficient water for both current and projected needs.

Mexico:

Fuel: In Mexico, since 2018, we have purchased fuel from Petroleos Mexicanos (“PEMEX”), the state producer, and from private suppliers.

The La Caridad unit imports natural gas from the United States through its pipeline (between Douglas, Arizona and Nacozari, Sonora). This allows us to import natural gas at market prices and thereby reduce operating costs. Several contracts with PEMEX and the United States provide us with the option of using a monthly or daily fixed prices for our natural gas purchases.

Natural gas is used for metallurgical processes and to power furnaces, converters, casting wheels, boilers and electric generators. Diesel oil is a backup method for all these uses. We use diesel oil to power mining equipment at our operations.

Electricity: Electricity is used as the main energy source at our mining complexes. We purchase most of our electricity from Mexico Generadora de Energia S. de R. L. (“MGE”), a subsidiary of Grupo Mexico which has two power plants designed to supply power to La Caridad and Buenavista units. MGE supplies 2.3% of its power output to third party energy users. These plants are natural gas-fired combined cycle power generating units, with a net total capacity of 516.2 megawatts. In 2012, we entered into a power supply agreement with MGE that will last until 2032. The first plant was

11

Table of Contents

completed in 2013 and the second in the second quarter of 2014. The first plant began to supply power to the Company in December 2013, and the second plant in June 2015.

We also purchase electricity from the Comision Federal de Electricidad (the Federal Electricity Commission or the “CFE”), the state’s electrical power producer. In addition, we recover some energy from waste heat boilers at the La Caridad smelter. Accordingly, a significant portion of our operating costs in Mexico is dependent upon the pricing policies of CFE and PEMEX, which are affected by political and regulatory environments, international market prices for crude oil and natural gas; and conditions in the refinery markets.

Some IMMSA mining operations also purchase electricity from Eolica el Retiro, S.A.P.I de C.V. (“Eolica”), a windfarm energy producer that is an indirect subsidiary of Grupo Mexico. In August 2013, IMMSA and other of the Company’s mining operations entered into a purchase agreement and in late 2014 started to purchase electricity from Eolica. Due to the nature of the production process there is not a fixed power capacity contracted. In 2020, total purchases were approximately 12.1 million kilowatt hours.

Water: In Mexico, water is deemed public property and industries that are not connected to a public service water supply must obtain a water concession from Comision Nacional del Agua (the National Water Commission or the “CNA”). Water usage fees are established in the Ley Federal de Derechos (the Federal Rights Law), which distinguishes several availability zones with different fees per unit of volume according to each zone, with the exception of Mexicana de Cobre. All of our operations have one or several water concessions and pump out the required water from wells. Mexicana de Cobre pumps water from the La Angostura dam, which is close to the mine and plants. At our Buenavista facility, we maintain our own wells and pay the CNA for water usage. Water conservation committees have been established at each plant to conserve and recycle water. Water usage fees are updated on a yearly basis and have been on the rise in recent years.

LEGAL AND REGULATORY MATTERS

In 2019 and 2020, no legal, environmental, labor or tax regulations came into effect that required the Company to incur material costs of compliance, had material adverse effects on the Company’s operations, or affected normal execution of the Company’s projects. Additionally, we believe that all our facilities in Peru and Mexico are in material compliance with applicable environmental, mining and other applicable laws and regulations.

For a discussion of environmental and labor matters, reference is made to the information contained in Note 13 “Commitments and Contingencies” of the consolidated financial statements. For more information on tax matters, refer to Note 7 “Income taxes” of the consolidated financial statements.

MINING RIGHTS AND CONCESSIONS

We believe that our Peruvian concessions are in full force and effect under applicable Peruvian laws and as such, comply with all material terms and requirements applicable to said concessions. The concessions have indefinite terms, subject to our payment of concession fees of up to $3.00 per hectare annually for the mining concessions and a fee based on nominal capacity for the processing concessions. Fees paid during 2020, 2019 and 2018, were approximately

12

Table of Contents

$1.4 million, $1.8 million and $1.5 million, respectively. We have two types of mining concessions in Peru: metallic and non-metallic concessions.

In 2011, the Peruvian Congress approved an amendment to the mining royalty charge. The new mining royalty charge is based on operating income margins with graduated rates ranging from 1% to 12% of operating profits; the minimum royalty charge is equivalent to 1% of net sales. If the operating income margin is 10% or less, the royalty charge is 1% and for each 5% increment in the operating income margin, the royalty charge rate increases by 0.75%, up to a maximum of 12%. In 2020, 2019 and 2018, we made provisions of $60.6 million, $42.3 million and $32.9 million, respectively.

At the same time the Peruvian Congress amended the mining royalty charge, it enacted a new tax for the mining industry. This tax is also based on operating income and its rates range from 2% to 8.4%. For additional information see Note 7 “Income Taxes” to the consolidated financial statements.

Mexico:

In Mexico we have 503,104 hectares in concessions from the Mexican government for our exploration and exploitation activities as outlined on the table below:

We believe that our Mexican concessions are in full force and in effect under applicable Mexican laws and that we are in compliance with all material terms and requirements applicable to these concessions. Under Mexican law, mineral resources belong to the Mexican nation and a concession from the Mexican federal government is required to explore or mine mineral reserves. Mining concessions have a 50-year term that can be renewed for another 50 years. Holding fees for mining concessions can be from $0.36 to $7.92 per hectare depending on the start date of the mining concession. Fees paid during 2020, 2019 and 2018 were approximately $6.6 million, $7.1 million and $6.3 million, respectively. In addition, all of our operating units in Mexico have water concessions that are in full force and effect. Although ownership is not required in order to explore or mine a concession, we generally own the land related to our Mexican concessions. We also own all of the processing facilities of our Mexican operations and the land on which they are built.

In December 2013, the Mexican government enacted a new law which, among other things, established a mining royalty charge of 7.5% on earnings before taxes as defined by Mexican tax regulations and an additional royalty charge of 0.5% over gross income from sales of gold, silver and platinum. These charges were effective January 2014 and are deductible for income tax purposes.

ITEM 1A. RISK FACTORS

Every investor or potential investor in Southern Copper Corporation should carefully consider the following risk factors.

Financial risks

Our financial performance is highly dependent on the price of copper and the other metals we produce.

Our financial performance is significantly affected by the market prices of the metals that we produce, particularly the market prices of copper, molybdenum, zinc and silver. Historically, these prices have been subject to wide fluctuations and are affected by numerous factors beyond our control, including international economic and political conditions, levels of supply and demand, the availability and costs of substitutes, inventory levels maintained by users, actions of participants in the commodities markets and currency exchange rates. In addition, the market prices of copper and certain other metals have on occasion been subject to rapid short-term changes. In 2020, the COVID-19 pandemic and consequent negative impact on the global economy created significant volatility in the financial markets, including the copper market.

13

Table of Contents

Over the last three years, approximately 81% of our revenues came from the sale of copper; 7% from molybdenum; 5% from silver; and 4% from zinc. Please see the distribution of our revenues per product on Item 8 “Financial Statements and Supplementary Data” Note 18 “Segment and Related Information—Sales value per segment” on page 157.

See also historical average price of our products on Item 1 Business caption “Metals prices”.

We cannot predict if metals prices will rise or fall in the future. Future declines in metals prices, and for copper in particular, will have an adverse impact on our results of operations and financial condition. Under very adverse market conditions, we might consider curtailing or modifying some of our mining and processing operations.

Our business requires levels of capital investments that we may not be able to maintain.

Our business is capital intensive. Specifically, the exploration and exploitation of copper and other metal reserves, mining, smelting and refining costs, the maintenance of machinery and equipment and compliance with laws and regulations require significant capital investments. We must continue to invest capital to maintain or increase the amount of copper reserves that we exploit and the amount of copper and other metals we produce. We cannot assure you that we will be able to maintain our production at levels that generate sufficient cash, or that we will have access to sufficient financing to continue our exploration, exploitation and refining activities at or above present levels.

Restrictive covenants in the agreements governing our indebtedness and the indebtedness of our Minera Mexico subsidiary may restrict our ability to pursue our business strategies.

Our financing instruments and those of our Minera Mexico subsidiary include financial and other restrictive covenants that, among other things, limit our and Minera Mexico’s abilities to incur additional debt and sell assets. If either we or our Minera Mexico subsidiary fails to comply with these obligations, we could be in default under the applicable agreements. This situation, if not addressed or waived, could require immediate repayment of debt obligations. Our Minera Mexico subsidiary is further limited by the terms of its outstanding notes, which also restrict the Company’s applicable incurrence of debt and liens. In addition, future credit facilities may contain limitations on our capacity to incur additional debt and liens; dispose of assets; or pay dividends to our common stockholders.

We may not pay a significant amount of our net income as cash dividends on our common stock in the future.

We have distributed a significant amount of our net income as dividends since 1996. Our dividend practice is subject to change at the discretion of our Board of Directors at any time. The amount that we pay in dividends is subject to a number of factors, including the results of our operations; our financial condition; cash requirements; tax considerations; future prospects; legal restrictions; contractual restrictions in credit agreements; limitations imposed by the government of Peru, Mexico or other countries where we have significant operations; and other factors that our Board of Directors may deem relevant. Depending on our capital investment program and global economic conditions, it is possible that future dividend distributions will fall below levels seen in recent years.

Our ability to recognize the benefits of deferred tax assets is dependent on future cash flows and taxable income.

Through 2020, the Company recognized the expected future tax benefit from deferred tax assets when the tax benefit was considered more likely than not to be realized. Assessing the recoverability of deferred tax assets requires management to make significant estimates related to expectations of future taxable income and existing tax laws. There can be no assurance that the Company will be able to recognize the expected future benefits of deferred tax assets; this inability could have a material adverse effect on the Company’s results of operations.

Operational risks

Our actual reserves may not conform to our current estimates of our ore deposits and our long-term viability depends on our ability to replenish ore reserves.

There is a degree of uncertainty attributable to the calculation of reserves. Until reserves are actually mined and processed, the quantity of ore and grades must be considered as estimates only. The proven and probable ore reserves data included in this report are estimates prepared by us based on evaluation methods generally used in the mining industry. We may be required in the future to revise our reserves estimates based on our actual production. We cannot assure you that our actual reserves conform to geological, metallurgical or other expectations or that the estimated volume and grade of ore will be recovered. Market prices of our metals, increased production costs, reduced recovery rates, short-term operating factors, royalty charges and other factors may render proven and probable reserves uneconomic to exploit and may result in revisions of reserves data from time to time. Reserves data are not indicative of future results of operations. Our reserves are depleted as we mine. We depend on our ability to replenish our ore reserves for our long-term viability. We use several strategies to replenish and increase our ore reserves, including exploration and investment in properties located near our existing mine sites and investing in technology that could extend the life of a mine by allowing us to cost-effectively process ore types that were previously considered uneconomic. Acquisitions may also contribute to increasing ore reserves and we review potential acquisition opportunities on a regular basis. However, we cannot assure you that we will be able to continue with our strategy to replenish reserves indefinitely.

Our operations are subject to risks, some of which are not insurable.

The business of mining, smelting and refining copper, zinc and other metals is subject to a number of risks and hazards, including industrial accidents, labor disputes, unusual or unexpected geological conditions, changes in the regulatory environment, environmental hazards, weather and other natural phenomena, such as seismic activity, wall failures and rock slides in our open-pit mines, structural collapses of our underground mines or tailings impoundments, and lower than expected ore grades or recovery rates. The Company’s operations may also be affected by mudslides and flash floods caused by torrential rains.

Such occurrences could result in damage to, or destruction of, mining operations resulting in monetary losses and possible legal liability. In particular, surface and underground mining and related processing activities present inherent risks of injury to personnel, loss of life and damage to equipment.

The waste rock and tailings produced in our mining operations represent our largest volume of waste material. Managing the volume of waste rock and tailings presents significant environmental, safety and engineering challenges and risks. We maintain large tailings impoundments containing sand of ground rock, moistened with water, which are effectively large dams that must be engineered, built and monitored to assure structural stability and avoid leakages or structural collapse. Defects, errors and failures at tailings dams and in other impoundments at any of our mining operations could cause severe property and environmental damage and loss of life. The importance of careful design, management and monitoring of large impoundments was emphasized in recent years by large scale tailings dam failures at unaffiliated mines, which caused extensive property and environmental damage and resulted in the loss of life. For more information regarding our tailing dams, please see Item 2 “Properties—Slope Stability—Tailing Dams.”

We maintain insurance against many of these and other risks, which under certain circumstances may not provide adequate coverage. Insurance against certain risks, including certain liabilities for environmental damage or hazards as a result of exploration and production, is not generally available to us or other companies within the mining industry. Nevertheless, recent environmental legal initiatives contemplate requirements for environmental damage insurance. If these regulations come into force, we will have to analyze the need to obtain said insurance. We do not have, and do not intend to obtain, political risk insurance. We cannot assure you that these and other uninsured events will not have an adverse effect on our business, properties, operating results, financial condition or prospects.

Changes in the demand level for our products and copper sales agreements could adversely affect our revenues.

Our financial results may be affected by fluctuations in demand for the refined, semi-refined metal products and concentrates we sell at both the industrial and consumer level, and may also be affected by changes in the global economy, including economic upturns and downturns of differing magnitudes. Changes in technology, industrial processes, concerns over weaknesses in the global economy and consumer habits may affect the level of demand to the extent that those increase or decrease the need for our metal products. Our revenues may also be adversely affected by events of force majeure that could have a negative impact on our sales agreements. These events include acts of nature, labor strikes, fires, floods, wars, transportation delays, government actions or other events that are beyond the control of the parties to the agreement.

Interruptions of energy supply or increases in energy, fuel and gas costs, shortages of water supply, critical parts, equipment, skilled labor and other production costs may adversely affect our results of operations.

We require substantial amounts of fuel oil, electricity, water and other resources for our operations. Fuel, gas and power costs constituted approximately 28% of our total production cost in 2020 and 2019, and 29% in 2018. We rely upon third parties for our supply of the energy resources consumed in our operations so that prices for and availability of energy resources may be subject to change or curtailment due to, among other things, new laws or regulations; imposition of new taxes or tariffs; interruptions in production by suppliers; and variations in global prices or market conditions. Regarding water consumption, although each operation currently has sufficient water rights to cover its operational demands, the loss of some or all water rights for any of our mines or operations, in whole or in part, or shortages relative to the water to which we have rights could require us to curtail or shut down mining production and could prevent us from pursuing expansion opportunities. In addition, future shortages of critical parts, equipment and skilled labor could adversely affect our operations and development projects.

Our Company is subject to health and safety laws that may restrict our operations, result in operational delays or increase our operating costs and adversely affect our financial results of operations.

We are required to comply with occupational health and safety laws and regulations in Peru and Mexico where our operations are subject to periodic inspections by the relevant governmental authorities. These laws and regulations govern, among others, health and safety workplace conditions, including high risk labor and the handling, storage and disposal of chemical and other hazardous substances. We believe our operations comply in all material respects with applicable health and safety laws and regulations in the countries in which we operate. Compliance with these laws and regulations and with new or existing regulations that may be applicable to us in the future could increase our operating costs and adversely affect our financial results of operations and cash flows.

Our objective is to preserve the health and safety of our workforce by implementing occupational health and training programs and safety incentives at our operations that meet all regulatory requirements and enhance employee performance. Despite the Company’s efforts, we are not exempt from accidents. These are reported to Mexican and Peruvian authorities as required. Regarding non-fatal accidents, in the last three years, the Company’s Dart rate (rate to measure workplace injuries severe enough to warrant Day Away from work, job Restrictions and/or job Transfers) was much lower than the MSHA Dart rate (the MSHA Dart rate is published by the U.S.’s Mine Safety and Health Administration, and is used as an industry benchmark).

In 2020 and 2018, no fatalities were reported at our operations in Mexico or Peru. Unfortunately, in 2019, we reported four fatalities in Mexico and Peru. The amounts paid to the Mexican and Peruvian authorities for reportable accidents had no adverse effects on our results. Under Mexican and Peruvian law penalties and fines for safety violations are generally monetary, but in certain cases may lead to the temporary or permanent shutdown of the affected facility or the suspension or revocation of permits or licenses. Additionally, violations of security and safety laws and regulations at our Peruvian operations can be considered criminal and punishable by a sentence of up to 10 years of prison.

Our metals exploration efforts are highly speculative in nature and may be unsuccessful.

Metals exploration is highly speculative in nature. It involves many risks and is frequently unsuccessful. Once mineralization is discovered, it may take a number of years from the initial phases of drilling until production is possible, during which time the economic feasibility of production may change. Substantial expenditures must be made to determine proven and probable ore reserves; this requires drilling to establish the metallurgical processes that will be needed to extract the metals from the ore and, in the case of new properties, to construct mining and processing facilities. We cannot assure you that our exploration programs will result in expansion or replacement of current production with new proven and probable ore reserves.

Development projects have no operating history upon which we can base estimates of proven and probable ore reserves and estimates of future cash operating costs. Estimates are, to a large extent, based upon the interpretation of geological data obtained from drill holes and other sampling techniques and on feasibility studies that generate estimates of cash operating costs based upon anticipated tonnage and grades of ore to be mined and processed; the configuration of the ore body; expected recovery rates of the mineral from the ore; comparable facility and equipment operating costs; anticipated climatic conditions; and other factors. As a result, actual cash operating costs and economic returns based upon development of proven and probable ore reserves may differ significantly from those originally estimated. Moreover, significant decreases in actual or expected prices may mean reserves, once found, will be uneconomical to produce.

We may be adversely affected by challenges relating to slope stability.

Our open-pit mines get deeper as we mine them, presenting certain geotechnical challenges including the possibility of slope failure. If we are required to decrease pit slope angles or provide additional road access to prevent such a failure, our stated reserves could be negatively affected. Furthermore, hydrological conditions relating to pit slopes, renewal of material displaced by slope failures and increased stripping requirements could also negatively affect our stated reserves. We take actions in order to maintain slope stability, but we cannot assure you that we will not have to take additional action in the future or that our actions taken to date will be sufficient. Unexpected slope failures, or additional requirements to prevent slope failures, may negatively affect our results of operations and financial condition and may diminish our stated ore reserves.

We may be adversely affected by labor disputes.

In the last several years we have experienced a number of strikes or other labor disruptions that have had an adverse impact on our operations and operating results. As of December 31, 2020, unions represented approximately 71% of our workforce. Currently, we have labor agreements in effect for our Mexican and Peruvian operations.

Our Taxco mine in Mexico has been on strike since July 2007. It is expected that operations at this mine will remain suspended until these labor issues are resolved. In addition, workers at the San Martin mine were on strike from July 2007 to August 2018. After eleven years of an illegal stoppage, we resumed control of the San Martin mine in August 2018. The San Martin facilities deteriorated during this period and we undertook a major renovation in order to restart operations during the second quarter of 2019, with an estimated capital budget of $97.7 million. For additional information, see Item 2, “Properties—Mexican IMMSA Unit—San Martin and Taxco”, and Note 13, “Commitments and Contingencies—Labor matters”, to the consolidated financial statements.

We cannot assure you when the pending strike will be settled, or that in the future we will not experience strikes or other labor related work stoppages that could have a material adverse effect on our financial condition and results of operations.

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

In recent years, worldwide mining activity has been pressured by neighboring communities for financial commitments to fund social benefit programs and infrastructure improvements. Our projects in Peru are not exempt from these pressures. Our Tia Maria project in Peru has experienced delays while trying to resolve issues with community groups.

It appears that in the Peruvian mining environment, it is becoming increasingly important to obtain acceptance from local communities for projects in their areas. This may entail demands for substantial investments in community infrastructure and upgrades that must be met in order to proceed with the mining projects.

We are confident that we will move forward with the Tia Maria project. However, we cannot assure you when and that we will incur no additional costs for community infrastructure and upgrades to obtain approval from the communities for current or future mining projects.

In addition, a number of collective action lawsuits and civil action lawsuits have been filed against the Company in Mexico through both federal courts and state courts in Sonora. A number of constitutional lawsuits have also been filed against various government authorities and against the Company. These lawsuits are seeking damages and demand remediation actions to restore the environment. The Company believes that it is not possible to determine the extent of the damages sought and believes the lawsuits are without merit. However, the Company cannot offer any assurances that the outcome of these lawsuits will not have adverse effects on the Company.

Environmental regulation, climate change and other regulations may increase our costs of doing business, restrict our operations or result in operational delays.

Our exploration, mining, milling, smelting and refining activities are subject to a number of Peruvian and Mexican laws and regulations, including environmental laws and regulations, and certain industry technical standards. Additional matters subject to regulation include, but are not limited to, concession fees, transportation, production, water use and discharge, power use and generation, use and storage of explosives, surface rights, housing and other facilities for workers, reclamation, taxation, labor standards, mine safety and occupational health.

Environmental regulations in Peru and Mexico have become increasingly stringent over the last decade and we have had to dedicate more time and money to compliance and remediation activities. Furthermore, the Mexican authorities have become more rigorous and stricter in enforcing Mexican environmental laws. We expect additional laws and regulations will be enacted over time with respect to environmental matters.

Please refer to Note 13 “Commitments and Contingencies—Environmental matters” of our financial statements for further information on this subject.

The potential physical impacts of climate change on our operations are highly uncertain and depend on the geographic location of our facilities. These may include changes in rainfall patterns, water shortages, changes in sea levels, storm patterns and intensities, and temperatures. These effects may adversely impact the cost, production and financial performance of our operations.

We monitor fluctuations in weather patterns in the areas where we operate. Aligned with government efforts, we are working to measure our carbon footprint to reduce our operations’ contributions to greenhouse gases. We also evaluate our water demand, as weather changes may result in increases or decreases that affect our needs.

Efforts to comply with more stringent environmental protection programs in Peru and Mexico and with relevant trade agreements could impose constraints on and imply additional costs for our operations; consequently, we may need to make significant investments in this regard in the future. We cannot assure you that current or future legislative, regulatory or trade developments will not have adverse effects on our business, properties, operating results, financial condition or prospects.

Our mining and metal production projects may expose us to new risks.

Our Company is in the midst of a large expansion program, which may expose us to additional risks in terms of industrial accidents. While we believe our contractors employ safety standards and other procedures to ensure these projects are completed with proper governance, it is possible that increased activity at our sites could cause environmental accidents or endanger human life.

Our business depends upon information technology systems that may be adversely affected by disruptions, damage, failure and risks associated with implementation and integration.

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. In 2020, we experienced no material cybersecurity breaches in our systems.

However, given the unpredictability of the timing, nature and scope of information technology disruptions, we could potentially be subject to manipulation or improper use of our systems and networks, operational delays, situations that compromise confidential or otherwise protected information, destruction or corruption of data, security breaches, or financial losses from remedial actions, any of which could have a material adverse effect on the cash flows, competitive position, financial condition or results of our operations.

Other risks

Applicable law restricts the payment of dividends from our Minera Mexico subsidiary to us.

Our subsidiary, Minera Mexico, is a Mexican company and, as such, may pay dividends only out of net income that has been approved by shareholders. Shareholders must also approve the actual dividend payment, after mandatory legal reserves have been created and losses for prior fiscal years have been satisfied. These legal constraints may limit the ability of Minera Mexico to pay dividends to us, which in turn, may have an impact on our ability to pay stockholder dividends or to service debt.

Global and local market conditions, including the high competitiveness in the copper mining industry, may adversely affect our profitability.

Our industry is cyclical in nature and fluctuates with economic cycles. Therefore, we are subject to the risks arising from adverse changes in domestic and global economic and political conditions, such as lower levels of consumer and corporate confidence, lower business investment, higher unemployment, reduced income and asset values in many areas, currency volatility and limited availability of credit and access to capital. Additionally, we face competition from other copper mining and producing companies around the world. Along these lines, significant competition exists to acquire properties that produce or are capable of producing copper and other metals, and some of our main competitors have consolidated, which makes them more diversified than we are.

We cannot assure you that changes in market conditions, including competition, will not adversely affect our ability to compete in the future on the basis of price or other factors with companies that may benefit from future favorable trading or other arrangements.

We are controlled by Grupo Mexico, which exercises control over our affairs and policies and whose interests may be different from yours.

At December 31, 2020, Grupo Mexico owned indirectly 88.9% of our capital stock. Some of our officers and directors, and those of Minera Mexico, are also directors and/or officers of Grupo Mexico and/or of its affiliates. We cannot assure you that the interests of Grupo Mexico will not conflict with those of our minority stockholders.

19

Table of Contents

Grupo Mexico has the ability to determine the outcome of substantially all matters submitted for a vote to our stockholders and thus exercises control over our business policies and affairs, including the following:

the composition of our Board of Directors and, as a result, any determinations of our Board with respect to our business direction and policy, including the appointment and removal of our officers;
determinations with respect to mergers and other business combinations, including those that may result in a change of control;
whether dividends are paid or other distributions are made and the amount of any dividends or other distributions;
sales and dispositions of our assets;
the amount of debt financing that we incur; and
the approval of capital projects.

We cannot assure you that an increase in the financial obligations of Grupo Mexico or AMC, which may be attributable to financing or to other reasons, will not result in a scenario in which our parent corporations obtain loans, increase dividends or receive other funding from us.

In addition, we have in the past engaged in, and expect to continue engaging in, transactions with Grupo Mexico and its other affiliates that are related party transactions and may present conflicts of interest. For additional information regarding the share ownership of, and our relationships with, Grupo Mexico and its affiliates, see Note 17 “Related Party Transactions” to the consolidated financial statements.

Unanticipated litigation or negative developments in pending litigation or with respect to other contingencies may adversely affect our financial condition and results of operations.

We are currently, and may in the future become, subject to litigation, arbitration or other legal proceedings with other parties. If rulings are against the Company, these legal proceedings, or others that could be brought against us in the future, may adversely affect our financial position or prospects. For further detailed discussion of pending litigation, please see Note 13 “Commitment and Contingencies—Litigation matters” of the consolidated financial statements.

Developments in the United States, Europe and emerging market countries may adversely affect the Company business, our common stock price and our debt securities.

The business and market value of securities of companies with significant operations in Peru and Mexico is, to varying degrees, affected by the economic policies and market conditions in the United States, Europe and emerging market countries. Although economic policies and conditions in these countries may significantly differ from policies and conditions in Peru or Mexico, the business community’s reactions to developments in any of these countries may adversely affect the Company business or the market value or trading price of securities, including debt securities, of issuers that have significant operations in Peru or Mexico.

In addition, in recent years economic conditions in Mexico have shown increased correlation to U.S. economic conditions. Therefore, changes in economic policies and conditions in the United States could also have a significant adverse effect on Mexican economic conditions, affecting our business, the price of our common stock or debt securities. In 2017, the United States, Canada and Mexico began a discussion to update the North American Free Trade Agreement (“NAFTA”). In September 2018, the three countries reached an agreement on a new trade deal, which will be known as the United States—Mexico—Canada Agreement (“USMCA”). In June 2019, Mexico’s senate ratified the UMSCA. In December 2019, the three countries agreed to a new review of its regional trade pact, also concluding that the USMCA would replace NAFTA. On January 29, 2020, the U.S. ratified the USMCA and its President signed the USMCA into law. On July 1, 2020, the USMCA came into effect.

Although recent developments in the U.S. have reduced political instability, lifted consumer confidence and boosted the U.S. stock market, it is unclear if the U.S. government will enact new policies with regard to China that will reduce or eliminate trade tensions between the two countries. Despite being the COVID-19 pandemic epicenter, China began 2021 with a relatively optimistic economic growth outlook. A slowing in China’s economic growth and copper demand and continued trade tensions between the U.S. and China could result in lower copper prices which could have a material

20

Table of Contents

adverse impact on our business and results of operations. The adoption and expansion of trade restrictions; changes in the state of China-U.S. relations, including on-going trade tensions; or other governmental action related to taxes, tariffs, trade agreements or other policies are difficult to predict, and could adversely affect demand for our products, our costs, our customers, our suppliers and the U.S. economy, and consequently, could have a material adverse effect on our cash flows, competitive position, financial condition or results of operations.

Additionally, there is uncertainty in global markets due to the June 2016 referendum in the United Kingdom, which resulted in a vote to leave the European Union (“Brexit”). In December of 2020, the United Kingdom left the European Union after an 11-month transition period that started in January. Brexit may adversely affect global political, regulatory, economic and market conditions, including capital markets and foreign exchange markets, which could adversely affect our business, financial condition and results of operations. It is likely that instability and volatility will continue in global financial markets until the terms of certain mechanisms of Brexit are clear.

We cannot assure you that the market value or trading prices of our common stock and debt securities, will not be adversely affected by events in the United States or elsewhere, including emerging market countries.

Other international risks

We are a company with substantial assets located outside of the United States. We conduct production operations in Peru and Mexico and exploration activities in these countries as well as in Chile, Argentina and Ecuador. Accordingly, in addition to the usual risks associated with conducting business in foreign countries, our business may be adversely affected by political, economic and social uncertainties in each of these countries. Such risks include possible expropriation or nationalization of property, confiscatory taxes or royalties, possible foreign exchange controls, changes in the national policy toward foreign investors, extreme environmental standards, etc.

Our international operations must comply with the U.S. Foreign Corrupt Practices Act and similar anti-corruption and anti-bribery laws in the other jurisdictions in which we operate. There has been a substantial increase in global enforcement of these laws in recent years. As such, our corporate policies and processes may not prevent or detect all potential breaches of law. Any violation of those laws could result in significant criminal or civil fines and penalties, litigation, and loss of operating licenses or permits, and may damage our reputation, which could have a material adverse effect on our cash flows, results of operations and financial condition.

Our insurance does not cover most losses caused by the aforementioned risks. Consequently, our production, development and exploration activities in these countries could be substantially affected by factors out of our control, some of which could materially and adversely affect our financial position or results of operations.

We may be adversely affected by natural disasters, pandemics (including the recent coronavirus outbreak) and other catastrophic events, and by man-made problems such as terrorism, which could disrupt our business operations and our business continuity; additionally, disaster recovery plans may not adequately protect us from a serious disaster.

Natural disasters, adverse weather conditions, floods, pandemics (including the recent coronavirus outbreak), acts of terrorism and other catastrophic or geo-political events may cause damage or disruption at our operations and in international commerce as well as the global economy, and could have an adverse effect on our business, operating results, and financial condition.

Our results of operations may be materially adversely impacted by the ongoing coronavirus pandemic (COVID-19).

The global spread of the coronavirus (COVID-19) has created significant volatility, uncertainty and economic disruption. Since the outbreak of the COVID-19 emerged in early 2020, it has quickly spread across the world.

The ongoing COVID-19 pandemic, coupled with the possibility that other pandemics may potentially arise in the future, represent significant risks for the Company, which include but are not limited to:

21

Table of Contents

a) supply chain disruptions that make it difficult for the Company to order and receive the materials needed to produce

its products and to ship finished products to our end customers,

b) financial risks pertaining to receivables due from customers that may become insolvent or otherwise unable to

meet their financial obligations,

c) government responses, including mandates that make it difficult to remain open for business; restrict imports of raw

materials or exports of finished goods; prohibit the Company’s products from being sold in their countries, and other

seen and unforeseen actions taken by government entities,

d) absenteeism or loss of employees at our Company, or at our affiliated companies, which involves workers needed to develop, validate, manufacture and perform other necessary functions for our operations, whether due to health reasons or government restrictions,

e) equipment failures due to maintenance postponements, loss of utilities and other disruptions that could impact our

operations or render them inoperable,

f) litigation or government actions against the Company,

g) a local or global recession or depression that could harm the international banking system, limiting demand for all

products, including those made by the Company,

h) disruption of banking and financial institutions, which may limit access to loans, and

i) many other seen and unforeseen events and circumstances, all of which could negatively impact the Company.

Risks Associated with Doing Business in Peru and Mexico

There is uncertainty as to the termination and renewal of our mining concessions.

Under the laws of Peru and Mexico, mineral resources belong to the state and government and concessions are required in both countries to explore for or exploit mineral reserves. In Peru, our mineral rights derive from concessions from Ministry of Energy and Mines (“MINEM”) for our exploration, exploitation, extraction and/or production operations. In Mexico, our mineral rights derive from concessions granted, on a discretionary basis, by the Ministry of Economy, pursuant to Mexican mining law and regulations thereunder.

Mining concessions in both Peru and Mexico may be terminated if the obligations of the concessioner are not satisfied. In Peru, we are obligated to pay certain fees for our mining concession. In Mexico, we are obligated, among other things, to explore or exploit the relevant concession, to pay any relevant fees, to comply with all environmental and safety standards, to provide information to the Ministry of Economy and to allow inspections by the Ministry of Economy. Any termination or unfavorable modification of the terms of one or more of our concessions, or failure to obtain renewals of such concessions subject to renewal or extensions, could have a material adverse effect on our financial condition and prospects.

Peruvian economic and political conditions may have an adverse impact on our business.

A significant portion of our operations is conducted in Peru. Accordingly, our business, financial condition or results of operations could be affected by changes in economic or other policies of the Peruvian government or other political, regulatory or economic developments in the country. Over the past several decades, Peru has had a succession of regimes with differing policies and programs. In the twentieth century, past governments have frequently intervened in the nation’s economy and social structure. Among other actions, past governments have imposed controls on prices, exchange rates and local and foreign investments; placed limitations on imports; restricted companies’ abilities to dismiss employees and have prohibited the remittance of profits to foreign investors.

In 2019 and 2020, Peru continued to experience heightened political instability in a context marked by ongoing investigations into allegations of corruption (Operation Car Wash investigation) and confrontation on the political scene. Significant political turmoil in Peru led to a shutdown of the Peruvian Congress and the removal of two Peruvian presidents.

Because we have significant operations in Peru, we cannot provide any assurance that political developments and economic conditions, including any changes to economic policies or the adoption of other reforms proposed by existing

22

Table of Contents

or future administrations, in Peru and/or other factors will have no material adverse effects on market conditions, the prices of our securities, our ability to obtain financing, our results of operations, or our financial condition.

Mexican economic and political conditions, as well as drug-related violence, may have an adverse impact on our business.

The Mexican economy is highly sensitive to economic developments in the United States, mainly because of its high level of exports to this market. Other risks in Mexico are increases in taxes on the mining sector and higher royalties, such as those enacted in 2013. As has occurred in other metal producing countries, the mining industry may be perceived as a source of additional fiscal revenue.

In addition, public safety organizations in Mexico are under significant stress, as a result of drug-related violence. This situation creates potential risks, particularly for transportation of minerals and finished products, which may affect a small portion of our production. Drug-related violence has had a limited impact on our operations, as it has tended to concentrate outside of our areas of production. The potential risks to our operations might increase if the violence spreads to our areas of production.

Because we have significant operations in Mexico, we cannot provide any assurance that political developments and economic conditions, including any changes to economic policies or the adoption of other reforms proposed by existing or future administrations in Mexico, or the advent of drug-related violence in the country, will have no material adverse effect on market conditions, the prices of our securities, our ability to obtain financing, our results of operations or our financial condition.

Peruvian inflation and fluctuations in the sol exchange rate may adversely affect our financial condition and results of operations.

Although the U.S. dollar is our functional currency and our revenues are primarily denominated in U.S. dollars, as we operate in Peru, portions of our operating costs are denominated in Peruvian soles. Accordingly, when inflation or deflation in Peru is not offset by a change in the exchange rate of the sol, our financial position, results of operations, cash flows and the market price of our common stock could be affected.

Inflation in Peru in 2020, 2019 and 2018 was 2.0%, 1.9% and 2.5%, respectively. The value of the sol depreciated against the U.S. dollar 9.3% and 4.1% in 2020 and 2018, respectively but it appreciated 1.8% in 2019. Although the Peruvian government’s economic policy reduced inflation and the economy has experienced significant growth in recent years, we cannot assure you that inflation will not increase from its current level or that such economic growth will continue in the future at similar rates or at all. Additionally, a global financial economic crisis could negatively affect the Peruvian economy.

To manage the volatility related to the risk of currency rate fluctuations, we may enter into forward exchange contracts. We cannot assure you, however, that currency fluctuations will not have an impact on our financial condition and results of operations.

Mexican inflation, restrictive exchange control policies and fluctuations in the peso exchange rate may adversely affect our financial condition and results of operations.

Although all of our Mexican operations’ sales of metals are priced and invoiced in U.S. dollars, a substantial portion of its costs are denominated in pesos. Accordingly, when inflation in Mexico increases without a corresponding depreciation of the peso, the net income generated by our Mexican operations is adversely affected. The annual inflation rate in Mexico was 3.2% in 2020, 2.8% in 2019 and 4.8% in 2018.

At the same time, the peso has been subject in the past to significant volatility, which may not have been proportionate to the inflation rate and may not be proportionate to the inflation rate in the future. The value of the peso relative to the U.S. dollar decreased by 5.9% in 2020, and it increased by 4.3% and 0.3% in 2019 and 2018, respectively.

23

Table of Contents

Currently, the Mexican government does not restrict the ability of Mexican companies or individuals to convert pesos into dollars or other currencies. While we do not expect the Mexican government to impose any restrictions or exchange control policies in the future, it is an area we closely monitor. We cannot assure you the Mexican government will maintain its current policies with regard to the peso or that the peso’s value will not fluctuate significantly in the future. The imposition of exchange control policies could impair Minera Mexico’s ability to obtain imported goods and to meet its U.S. dollar-denominated obligations and could have an adverse effect on our business and financial condition.

REVIEW OF OPERATIONS

The following maps show the locations of our principal mines, smelting facilities and refineries. We operate open-pit copper mines in the southern part of Peru—at Toquepala and Cuajone—and in Mexico, at La Caridad and Buenavista. We also operate five underground mines that produce zinc, copper, silver and gold.

Graphic

EXTRACTION, SMELTING AND REFINING PROCESSES

Our operations include open-pit and underground mining, concentrating, copper smelting, copper refining, copper rod production, solvent extraction/electrowinning (“SX-EW”), zinc refining, sulfuric acid production, molybdenum concentrate production and silver and gold refining. The extraction and production process are summarized below.

24

Table of Contents

OPEN-PIT MINING

In an open-pit mine, the production process begins at the mine pit, where waste rock, leaching ore and copper ore are drilled and blasted and then loaded onto diesel-electric trucks by electric shovels. Waste is hauled to dump areas and leaching ore is hauled to leaching dumps. The ore to be milled is transported to the primary crushers.

UNDERGROUND MINING

In an underground mine, the production process begins at the stopes, where copper, zinc and lead veins are drilled and blasted and the ore is hauled to the underground crusher station. The crushed ore is then hoisted to the surface for processing.

CONCENTRATING

The copper ore with a copper grade over 0.4% from the primary crusher or the copper, zinc and lead-bearing ore from the underground mines is transported to a concentrator plant where gyratory crushers break the ore into sizes no larger than three-quarter of an inch. The ore is then sent to a mill section where it is ground to the consistency of fine powder. The finely ground ore is mixed with water and chemical reagents and pumped as a slurry to the flotation separator, where it is mixed with certain chemicals. In the flotation separator, reagent solutions and air pumped into the flotation cells cause the minerals to separate from the waste rock and bubble to the surface where they are collected and dried.

If the bulk concentrated copper contains molybdenum, it is first processed in a molybdenum plant as described below under “Molybdenum Production.”

COPPER SMELTING

Copper concentrates are transported to a smelter, where they are smelted using a furnace, converter and anode furnace to produce either blister copper (which is in the form of cakes with air pockets) or copper anodes (which are cleaned of air pockets). At the smelter, the concentrates are mixed with flux (a chemical substance intentionally included for high temperature processing) and then sent to reverberatory furnaces producing copper matte and slag (a mixture of iron and other impurities). Copper matte contains approximately 65% copper. Copper matte is then sent to the converters, where the material is oxidized in two steps: (i) the iron sulfides in the matte are oxidized with silica, producing slag that is returned to the reverberatory furnaces, and (ii) the copper contained in the matte sulfides is then oxidized to produce copper that, after casting, is called blister copper, containing approximately 98% to 99% copper, or anodes, containing approximately 99.7% copper. Most of the blister and anode production is sent to the refinery and the remainder is sold to customers.

COPPER REFINING

Anodes are suspended in tanks with a solution containing water, sulfuric acid and copper sulfate. A weak electrical current is passed through the anodes and chemical solution and the dissolved copper is deposited on very thin starting sheets to produce copper cathodes containing approximately 99.99% copper. During this process, silver, gold and other metals (for example, palladium, platinum and selenium), along with other impurities, settle on the bottom of the tank (anodic muds). This anodic mud is processed at a precious metal plant where selenium, silver and gold are recovered.

COPPER ROD PLANT

To produce copper rod, copper cathodes are first smelted in a furnace and then dosed in a casting machine. The dosed copper is then extruded and passed through a cooling system that begins solidification of copper into a 60×50 millimeter copper bar. The resulting copper bar is gradually stretched in a rolling mill to achieve the desired diameter. The rolled bar is then cooled and sprayed with wax as a preservation agent and collected into a rod coil that is compacted and sent to market.

25

Table of Contents

SOLVENT EXTRACTION/ELECTROWINNING (“SX-EW”)

A complementary processing method is the leaching and SX-EW process. During the SX-EW process, low-grade sulfides ore and copper oxides are leached with sulfuric acid to allow copper content recovery. The acid and copper solution is then agitated with a solvent that contains chemical additives that attract copper ions. As the solvent is lighter than water, it floats to the surface carrying with it the copper content. The solvent is then separated using an acid solution, freeing the copper. The acid solution containing the copper is then moved to electrolytic extraction tanks to produce copper cathodes.

MOLYBDENUM PRODUCTION

Molybdenum is recovered from copper-molybdenum concentrates produced at the concentrator. The copper-molybdenum concentrate is first treated with a thickener until it becomes slurry with 60% solids. The slurry is then agitated in a chemical and water solution and pumped to the flotation separator. The separator creates a froth that carries molybdenum to the surface but not the copper mineral (which is later filtered to produce copper concentrates containing approximately 27% copper). The molybdenum froth is skimmed off, filtered and dried to produce molybdenum concentrates of approximately 58% contained molybdenum.

ZINC REFINING

Metallic zinc is produced through electrolysis using zinc concentrates and zinc oxides. Sulfur is eliminated from the concentrates by roasting and the zinc oxide is dissolved in sulfuric acid solution to eliminate solid impurities. The purified zinc sulfide solution is treated by electrolysis to produce refined zinc and to separate silver and gold, which are recovered as concentrates.

SULFURIC ACID PRODUCTION

Sulfur dioxide gases are produced in the copper smelting and zinc roasting processes. As a part of our environmental preservation program, we treat the sulfur dioxide emissions at two of our Mexican plants and at our Peruvian processing facilities to produce sulfuric acid, some of which is, in turn, used for the copper leaching process; the balance is sold to mining and fertilizer companies located mainly in Mexico, Peru, United States and Chile.

SILVER AND GOLD REFINING

Silver and gold are recovered from copper, zinc and lead concentrates in the smelters and refineries and from slimes through electrolytic refining.

SLOPE STABILITY:

Peruvian Operations

The Toquepala and Cuajone pits are each approximately 930 meters deep. Under the present mine plan configuration the Toquepala pit will reach a depth of 1,605 meters and the Cuajone pit will reach a depth of 1,380 meters. The increases in the depth of the pits present us with a number of geotechnical challenges. Perhaps the foremost concern is the possibility of slope failure, which all open-pit mines face. In the past, in order to maintain slope stability, we have decreased pit slope angles, installed additional or duplicate haul road access, and increased stripping requirements. We have also responded to hydrological conditions and removed material displaced by slope failures. To meet the geotechnical challenges relating to slope stability of the open-pit mines, we have taken the following steps:

In the late 1990s, we hosted round table meetings with a group of specialists to review pit designs for mines with depths greater than 700 meters. Based on the concepts defined at these meetings, we initiated slope stability studies to define the mining of reserves by optimum design. The studies were completed in 2000 and we believe we have implemented the study recommendations. One of the major changes implemented was slope angle reduction at both mines.

Since 1998, a wall depressurization program has been in place in both pits. This consists of a horizontal drilling program, which improves drainage thereby reducing saturation and increasing wall stability. Additionally, a new blasting control program was put in place and a new slope monitoring system was implemented.

Toquepala:

In 2007, we installed 20 meter wide geotechnical berms every 10 benches at the Toquepala mine. We believe this will further strengthen the stability of the Toquepala pit. In October 2012, two interferometric radars were put in place to monitor slope stability at the Toquepala mine, and in September 2013, new full monitoring software (FMS360) was installed. These systems improve the reliability of instrumentation, the information quality for assessing the behavior of the slopes and anticipates the risks of instability.

In 2013, a mining consulting group began a study of dump stability at the Toquepala mine. This study assessed the current stability of the dumps and is developing a geotechnical campaign to obtain information to assess the stability of the future and final stages of the dumps. In 2016, the stability study was resumed by executing geophysical test and test pits to characterize the dumps. The execution of sonic perforations and complementary geophysical tests are currently pending. On December 2016, the consultants also presented the report “Slope Stability Analysis in Deposits of Waste and Leachable Material”.

In 2016, the mining consultants presented the final report “Physical Stability of the Quebrada Honda tailings dam.” This study consisted in the development of geotechnical investigations, static, seismic and post-seismic stability analysis, filtration analysis, deformation analysis, liquefaction potential analysis and dynamic analysis.

In 2016, as part of the slope stability upgrade study, a geotechnical and hydrological oriented drill program of 3,470 meters was executed at the Toquepala mine. This program was conducted in order to complement the study and to gain a better understanding of the behavior of the rock mass. The geotechnical drilling program involved 11 diamond drill holes, six geotechnical drills and five hydrogeological drills, all of which entailed geological and geotechnical logging. During the execution of these hydrogeological drills, permeability tests in the rock were executed as well as slug tests and constant load tests. Additionally, instrumentation was implemented with five vibrating wire piezometers for the monitoring of water table and to give support to the hydrogeological model. In 2016, the external mining consultants began the report for phase three of this study, which was concluded in 2017. They submitted and updated the block models of inter-ramp angles, the model of rock mass, the hydrogeological model and the 3D structural model. In addition, fieldwork continued on the “Slope Stability Analysis in Deposits of Waste and Leachable Material” study by executing geophysical tests, sampling and laboratory tests of soil mechanics. This study was concluded and submitted by the external consultants in 2018.

Additionally, in 2018 we dedicated efforts to update the geotechnical pit models, which are essential to perform the analysis of slope stability. Related to this, we have carried out actions, including the completion of the geotechnical database implementation, laboratory testing, training, and other important aspects. In 2019, external consultants performed the “2019 Update of Slope Stability Analysis in Deposits of Waste and Leachable Material” study. In addition, an IBIS ArcSAR radar was incorporated into the pit slope monitoring system; this radar equipment offers greater coverage, five kilometers of maximum range and reduced scanning time. Sub- horizontal drains were also implemented for pit slope depressurization.

In 2020, external consultants performed the “Stability Study of the Toquepala Pit in Current Conditions” and “Stability Study of the North, South, East, Northwest Waste Deposits and South Run of Mine (ROM) and Northwest Leach Deposits.” In addition, another IBIS ArcSAR radar, which has a maximum range of five kilometers and offers reduced scanning time, was incorporated into the pit slope monitoring system. We also implemented a database for geotechnical drillholes, implemented the project “Automation and Real Time Monitoring of geotechnical instrumentation in the Pit and Quebrada Honda Tailings Dam” and conditioned a location to install three radars to conduct geotechnical monitoring of the Quebrada Honda Tailings Dam.

In recent years, we have made significant efforts to conduct stability studies of the slopes of the pit, dumps and leachable deposits and tailings to safeguard personnel and equipment; ensure the continuity of operations; and comply with Peruvian regulations.

Cuajone:

At the Cuajone mine, in 2007 in order to minimize the damage to the slopes caused by production blast vibrations, blasting control using three pre-split drills was implemented. Also, the slope monitoring system with reflection prisms has been replaced by a system using slope monitoring radar. In February 2012, the first radar equipment was put in service and in August 2013, the second radar installation and a geotechnical surveillance camera was added. This system improved the reliability and continuity of monitoring, improved the quality of information used to evaluate the performance of the slopes and helped better anticipate the risk of instability. The sub-surface deformation and the water level are still monitored with inclinometers and piezometers. In September 2012, we completed a program of oriented geotechnical drilling totaling 17,938 meters, and in May 2013 we completed a program of vertical geotechnical drilling totaling 2,814 meters, with hydraulic tests performed on rock and subsequently instrumented with inclinometers/piezometers. The geotechnical and hydraulic information obtained from the two programs will be used in the development of a geotechnical study for the new 15-year mine development plan (2015-2029). Additionally, in 2013, we drilled 772 meters of sub-horizontal holes to drain the east slope of the pit. The geotechnical study for the new 15-year mine development plan was completed at the end of 2015, and the result of this study is the increase of the inter ramp angle by an average of three degrees and include 40 meters wide geotechnical berms for inter ramp heights above 150 meters. This study also contains recommendations for improving the stability of the pit slopes.

In 2013, the Board of Directors approved a project to improve slope stability in the southern area of the Cuajone mine, which will remove approximately 148 million tons of waste material to improve the mine design without reducing our actual production level. As of December 31, 2020, 146.4 million tons of waste material had been removed. For further information see Item 7 “Management Discussion and Analysis—Capital Investment Program.”

In 2017, we installed three vibration monitoring stations and ten digital extensometers to monitor surface deformations on waste dumps in real time. We also completed the detailed engineering for the construction of the coronation channel in the west Torata waste dump. In 2018, we began to operate the first radar to monitor blasting vibrations and set up a second geotechnical surveillance camera. This equipment will allow us to improve control over the walls of the pit and to anticipate possible damages.

In 2020, equipment to extract rock samples was implemented in the rock mechanics laboratory. This equipment allows us to obtain cylindrical rock specimens and perform rock mechanics tests under current technical standards and norms. A drone was also incorporated in the slope reconciliation activities to obtain detailed topographic information on the slopes and identify good practices or opportunities to build stable walls.

To increase the possibility of mining in the event of a slide, we have provided for two extraction ramps for each open-pit mine. While these measures cannot guarantee that a slope failure will not occur, we believe that our mining practices are sound and that the steps taken and the ongoing reviews performed are a prudent methodology for open-pit mining.

Mexican operations

In 2004, our 15-year mine plan study for the La Caridad mine was awarded to an independent consulting firm to conduct a geotechnical evaluation. The purpose of the plan was to develop a program of optimum bench design and inter-ramp slope angles for the open-pit. The results of the evaluation presented by the consultants included a recommendation of a maximum average bench face angle of 72 degrees. Additionally, single benching was recommended for the upper sections of the west, south and east walls of the main pit. Double benching was recommended for the lower levels of the main pit and single benching for the upper slope segments that consist of either alluvial material, mine waste dumps or mineralized stockpile material. Alternatively, slopes in these types of materials, may be designed with an overall 37-degree slope. The geostructural and geotechnical parameters recommended were applied in the pit design for the new life of mine plan for La Caridad mine, which was prepared in 2015. This mine plan replaced the 15-year mine plan prepared in 2010. However, since final pit limits have yet to be established at La Caridad, all current pit walls are effectively working slopes. Geostructural and geotechnical data collected at the open-pit mine from cell-mapping and oriented-core drilling databases provided the basis for the geotechnical evaluation and recommendations.

In 2019, we assigned an independent consulting firm to conduct a geotechnical study of La Caridad, which included the Bella Union area, based on a 15-year mining plan. The results of this study included recommendations on geostructural and geotechnical parameters. These were applied to the pit design for the new mine plan for La Caridad, which replaced the 15-year mine plan prepared in 2015. We continue to collect new information related to geotechnical data and other geology features from the mine pit and diamond drill hole to ensure structural security and improve the geotechnical data base for future studies.

At the Buenavista mine, we are following the recommendations produced by a geotechnical evaluation of the design slope for the 15-year pit plan. This evaluation was prepared by an independent mine consulting firm. The assessment included the determination of optimum pit slope design angles and bench design parameters for the proposed mine plan. The objective of the study was: (1) to determine optimum inter-ramp slope angles and bench design parameters for the 15-year plan and (2) to identify and analyze any potential major instability that could adversely impact mine operation. In 2012, we installed a radar system to monitor the walls of the mine.

The following recommendations were made for the Buenavista mine: inter-ramp slope design angles for the 15-year pit plan for all of the 21 design sectors defined on a rock-fabric-based catch bench analysis, using double bench, can range from 48° and 55°, and the inter-ramp slope angles are based on geometries obtained from the back-break analysis using 80% reliability of achieving the required 7.5 meter catch bench width for a single bench configuration and 10.6 meter catch bench width for a double bench configuration. Preliminary observations suggest the 15-year pit walls may be relatively free-draining; the back-break analysis assumed depressurized conditions of mine benches, and the inter-ramp stability analysis were performed for both saturated and depressurized conditions.

A pit dewatering/depressurization plan for the Buenavista mine was also recommended to address the issues of open-pit drainage, dewatering plan and future slope depressurization. Phase I of the geohydrological study was completed by an independent consultant. The analysis included a preliminary assessment and work plan implementation.

In 2011, five wells for extraction and monitoring were drilled close to the mine. Also, we began a drilling program to monitor possible water filtration beyond the limits of the open-pit mine. All the information obtained from these well drilling programs has been analyzed and included in the hydrologic model. The open-pit dewatering program from the bottom benches also continued in 2012 with a drilling program of 3,797 meters, which was conducted at in several monitoring wells to ensure the ability to continue with the current mining plan.

In 2013, Buenavista continued the drilling program monitoring the extraction wells in the area of Increment (Phase) five of the mine and beyond the current limits of the open pit mine.

In 2013, the program to dewater the Buenavista pit bottom continued, in accordance with the short and medium term mine plans. Pumping from sumps located in Increment five, permitted mining of high-grade copper blocks. Concurrent with this operational task, a geophysical study was conducted to determine the best locations for water extraction wells to control the inflow of water to the pit bottom and allow us to continue our mining operations. The water extracted is being used for various purposes, including road irrigation for dust mitigation. The geophysical investigation also permitted the location of underground workings and filtration and seepage through fractures.

A total of 7,339 meters was drilled in 2013 for 30 extraction wells, three of these wells are located in the area of Increment (Phase) five. The rest were drilled at various locations outside of the current open pit mine limit.

In 2014, we continued collecting new geotechnical information from two exploration drilling projects; this data is available to analyze the geotechnical data base for new studies in accordance with slope angle for the open pit excavations. In the free face benches at the open pit mine operations, the cell-mapping were prepared to increment the geotechnical database. Following the recommendations of the geotechnical evaluation, we continued monitoring the walls using the radar system.

Various studies are now being conducted by outside specialized consultants to establish long-range mine water management objectives and implement recommendations for the efficient use of this resource. We are also conducting a geotechnical study and a diamond drilling program with an independent consulting firm in order to obtain additional geotechnical information, which will allow us to verify the slope stability for the long-term mine plan. In addition, slope monitoring continues with the SSR 160 radar.

In July 2020, the OMNI 505 radar began operating. As such, we currently have two working radars, which allow us to cover 95% of the slopes in the operating areas of the mine. We also plan to add two total stations with prisms to this instrumentation. In addition, we expect to begin developing a geotechnical model for the mine, which includes reviewing the hydrological model of the deposit.

Tailings Dams

Tailings are comprised of solid particles originating at the concentrator plants during the grinding process that, combined with water, are sent to specially built structures where they are impounded. The water is recovered to be reused in the process.

Tailings dams are basically built in two manners: by using the coarse fraction from the same tailings or by using external material, often known as “borrowed material” such as rock, clay etc. We believe SCC’s tailings dams are built with the highest quality standards and engineering practices. We comply with and at times exceed the national norms and recommendations of the International Commission on Large Dams (ICOLD). In addition, we maintain a committee including both internal and external specialists, which periodically review the safety and operation of each dam. In 2020, we implemented the project “Automation and Real Time Monitoring of geotechnical instrumentation in the Pit and Quebrada Honda Tailings Dam” and conditioned a location to install three radars to conduct geotechnical monitoring of the Quebrada Honda Tailings Dam. We do not expect that these activities will generate any adverse material effects in our operations.

We have six tailings dams in operation in Mexico and one in Peru as follows:

Geology

The Cuajone porphyry copper deposit is located on the western flank of Cordillera Occidental in the southern-most region of the Andes mountains range of Peru. The deposit is part of a mineral district that contains two additional known deposits, Toquepala and Quellaveco. The copper mineralization at Cuajone is typical of porphyry copper deposits.

The Cuajone deposit is located approximately 30 kilometers north-west from the Toquepala deposit and is part of the Toquepala Group, which dates back approximately 60 to 100 million years (Upper Cretaceous to Lower Tertiary). The Cuajone lithology contains volcanic rocks from the Cretaceous to the Quaternary period. The deposit contains 50 rock types including, pre-mineral rocks, basaltic andesite, porphyritic rhyolite, Toquepala dolerite, Toquepala rhyolite and intrusive rocks, including diorite, porphyritic latite, breccias and dikes. In addition, the following post-mineral rocks are present: the Huaylillas and Chuntacala formations, which have been formed by conglomerates, tuffs sequence, traquites and agglomerates. These formations date from nine to 23 million years. There is also the occurrence of Quaternary rocks, which were formed by alluvial and colluvial mainly located in slopes of hills and streams.

The mineralogy is simple and is evenly distributed. It is mainly composed of minerals such as chalcopyrite (CuFeS2), chalcosine (Cu2S) and molybdenite (MoS2) with occasional presence of galena, enargite and tetraedrite, none of which have economic value.

Concentrator

Our Cuajone operations use state-of-the-art computer monitoring systems at the concentrator, the crushing plant and the flotation circuit to coordinate inflows and optimize operations. Material with a copper grade over 0.35% is loaded onto an overland conveyor belt and sent to the milling circuit, where giant rotating crushers reduce the size of the rocks to approximately one-half of an inch. The ore is then sent to the ball mills, which grind it to the consistency of fine powder. The finely ground powder is agitated in a water and reagents solution and is then transported to flotation cells. Air is pumped into the cells to produce foam for floating the copper and molybdenum minerals while waste materials called tailings are separated. This copper-molybdenum bulk concentrate is then treated by inverse flotation, where molybdenum is floated and copper is depressed. The copper concentrate is shipped by rail to the smelter at Ilo and the molybdenum concentrate is packaged for shipment to customers. Sulfides under 0.35% copper are considered waste.

Tailings are sent to thickeners to recover water. The remaining tailings are sent to the Quebrada Honda dam, our principal tailings storage facility.

A major mill expansion was completed in 1999 and the eleventh primary mill began operations in January 2008. In December 2013, the high-pressure grinding roll was put in operation. At the end of 2016, the Larox filter press for molybdenum concentrate began operations. The overland primary crusher began operations in May 2018. The new tailings thickener began operations in September 2019.

Toquepala

Our Toquepala operations consist of an open-pit copper mine and two concentrators. We also refine copper at the SX-EW facility through a leaching process. Toquepala is located in southern Peru, 30 kilometers from Cuajone and 870 kilometers from Lima at an altitude of 3,220 meters above sea level. Access is by plane from Lima to the city of Tacna (1:40 hours) and then by the Pan-American highway to Camiara (1:20 hours) and by road to Toquepala (1 hour). Each concentrator has a milling capacity of 60,000 tons per day. The SX-EW facility has a production capacity of 56,000 tons per year of LME grade A copper cathodes. Overburden removal commenced in 1957 and ore production commenced in 1960. Our Toquepala operations utilize a conventional open-pit mining method to collect copper ore for further processing in our concentrators. The second concentrator began operations in the fourth quarter of 2018.

Geology

The Toquepala porphyry deposit is located on the western slopes of Cordillera Occidental in the southern-most region of the Andes mountains range of Peru and approximately 120 kilometers from the border with Chile. This region extends into Chile and is home to many of the world’s most significant known copper deposits. The deposit is part of a mineral district that contains two additional known deposits, Cuajone and Quellaveco. The deposit is in a territory with intrusive and eruptive activities of rhyolitic and andesitic rocks, which are 70 million years old (Cretaceous-Tertiary) and have created volcanic lava. The lava is composed of rhyolites, andesites and volcanic agglomerates with a western dip and at an altitude of 1,500 meters. These series are known as the Toquepala Group. Subsequently, different intrusive activities occurred that broke and smelted the rocks of the Toquepala Group. These intrusive activities resulted in diorites, granodiorites and dikes of porphyritic dacite. Toquepala has a simple mineralogy with regular copper grade distribution. Economic ore is found as disseminated sulfurs throughout the deposit as veinlets that replenish empty places or as small aggregates. Ore minerals include chalcopyrite (CuFeS2), chalcosine (Cu2S) and molybdenite (MoS2). A secondary enrichment zone is also present with thicknesses between 0 and 150 meters.

Concentrators

Our Toquepala concentrators use state-of-the-art computer monitoring systems to coordinate inflows and optimize operations. Material with a copper grade over 0.25% is loaded onto an overland conveyor belt and sent to the crushing circuit, where rotating crushers reduce the size of the rocks by approximately 85% to less than one-half of an inch. The ore is then sent to the rod and ball mills, which grind it in a mix with water to the consistency of fine powder. The finely ground powder mixed with water is then transported to flotation cells. Air is pumped into the cells producing a froth, which carries the copper mineral to the surface but not the waste rock, or tailings. The bulk concentrate with sufficient molybdenum content is processed to recover molybdenum by inverse flotation. This final copper concentrate with a content of approximately 26.5% of copper is filtered to reduce moisture to 8.5% or less. Concentrates are then shipped by rail to the Ilo smelter.

Tailings are sent to thickeners where water is recovered. The remaining tailings are sent to the Quebrada Honda dam, our principal tailings storage facility.

SX-EW Plant

The SX-EW facility at Toquepala produces grade A LME electrowon copper cathodes of 99.999% purity from solutions obtained by leaching low-grade ore stored at the Toquepala and Cuajone mines. The leach plant commenced operations in 1995 with a design capacity of 35,629 tons per year of copper cathodes. In 1999, the capacity was expanded to 56,000 tons per year.

This facility processes copper oxides from Cuajone and copper sulfides from Toquepala. Copper oxides from Cuajone with a copper grade higher than 0.520%; acid solubility index higher than 51%; and a cyanide solubility index higher than 25% are leached. At Toquepala, the copper sulfides cutoff grade is 0.080% and therefore, material with a total copper grade between 0.080% and 0.294% is leached. Copper in solution produced at Cuajone is sent to Toquepala through an eight-inch pipe laid alongside the Cuajone-Toquepala railroad track.

Plant and equipment are supported by a maintenance plan and a quality management system to assure good physical condition and high availability. The SX-EW plant management quality system (including leaching operations) has been audited periodically since 2002 by an external audit company and found to be in compliance with the requirements of ISO 9001-2008, OHSAS 18001-2007 and ISO 14001-2015 standards.

Processing Facilities—Ilo

Our Ilo smelter and refinery complex is located in the southern part of Peru, 17 kilometers north of the city of Ilo, 121 kilometers from Toquepala, 147 kilometers from Cuajone and 871 kilometers from the city of Lima. Access is by plane from Lima to Tacna (1:40 hours) and then by highway to the city of Ilo (2:00 hours). Additionally, we maintain a port facility in Ilo, from where we ship our products and receive supplies. Products shipped and supplies received are moved between Toquepala, Cuajone and Ilo on our industrial railroad.

Smelter

Our Ilo smelter produces copper anodes for the refinery we operate as part of the same facility. When the copper produced by the smelter exceeds the refinery’s capacity, the excess is sold to other refineries around the world. In 2007, we completed a major modernization of the smelter. The nominal installed capacity of the smelter is 1,200,000 tons of

Table of Contents

copper concentrate per year. Copper concentrates from Toquepala and Cuajone are transported by railroad to the smelter, where they are smelted using an ISASMELT furnace, converters and anode furnaces to produce copper anodes with 99.7% copper. At the smelter, the concentrates are mixed with flux and other material and sent to the ISASMELT furnace producing a mixture of copper matte and slag, which is tapped through a taphole to either of two rotary holding furnaces, where these smelted phases will be separated. Copper matte contains approximately 63% copper. Copper matte is then sent to the four Pierce Smith converters, where the material is oxidized in two steps: (1) the iron sulfides in the matte are oxidized with oxygen enriched air and silica is added producing slag that is sent to the slag cleaning furnaces, and (2) the copper contained in the matte sulfides is then oxidized to produce blister copper, containing approximately 99.3% copper. The blister copper is refined in two anode furnaces by oxidation and sulfur is removed with compressed air injected into the bath. Finally, the oxygen content of the molten copper is adjusted by reduction by injecting liquefied petroleum gas with steam into the bath. Anodes, containing approximately 99.7% copper, are cast in two casting wheels. The smelter also can produce blister copper bars, especially when an anode furnace is undergoing general repairs.

The off gases from the smelter are treated to recover over 92% of the incoming sulfur received in the concentrates to produce 98.5% sulfuric acid. The gas stream from the smelter with 11.34% SO2 is split between two plants: The No. 1 acid plant (single absorption/single contact) and the No. 2 plant (double absorption/double contact). Approximately, 16% of the acid produced is used at our facilities with the balance sold to third parties. We anticipate that our internal usage will be over 80% when the Tia Maria project begins operation. The smelter also has two oxygen plants. Plant No. 1, with 272 tons per day of production capacity, and Plant No.2, with 1,045 tons per day of capacity.

In 2010, the Ilo smelter marine trestle started operation. This facility allows us to offload directly to offshore ships the sulfuric acid produced, avoiding hauling cargo through the city of Ilo. The 500 meter long marine trestle is the last part of the Ilo smelter modernization project. Currently, all overseas shipments of sulfuric acid are shipped using the marine trestle.

Refinery

The Ilo refinery consists of an electrolytic plant, a precious metal plant and a number of ancillary installations. The refinery is producing grade A copper cathode of 99.998% purity. The nominal capacity is 294,763 tons per year. Anodic slimes are recovered from the refining process and then sent to the precious metals facility to produce refined silver, refined gold and commercial grade selenium.

Anodes are suspended in tanks containing a solution of sulfuric acid and copper sulfate. A low voltage but high amperage electrical current is passed through the anodes, chemical solution and cathodes to dissolve copper which is initially deposited on very thin starting sheets until thickness is increased to produce high grade copper cathodes. During this process, silver, gold and other metals, including palladium, platinum and selenium, along with other impurities, settle to the bottom of the tank in the form of anodic slime. This anodic slime is processed in a precious metal plant where silver, gold and selenium are recovered.

In addition to the processing facilities, the refinery has a production control section, a laboratory that provides sample analysis throughout the Company, a maintenance department, a desalinization plant and other support facilities.

Other facilities in Ilo include a coquina plant with a production capacity of 200,000 tons of seashells per year; this facility, however, has been declared in progressive closure. In addition, we had a lime plant with a capacity of 80,000 tons per year, which has suspended its operations. We also operate an industrial railroad to haul production and supplies between Toquepala, Cuajone and Ilo.

The industrial railroad’s main equipment includes locomotives of different types and rolling stock with different types of cars and capacities. The track runs in a single 214 kilometer standard gauge line and supports a 30-ton axle load. The total length of the track system is around 257 kilometers including main yards and sidings. The infrastructure includes 27 kilometers of track under tunnels and one concrete bridge. The industrial railroad includes a car repair shop which is responsible for maintaining and repairing the car fleet. Annual transported tonnage is approximately 5.9 million tons.

We have ongoing maintenance and improvement programs to ensure the satisfactory performance of our equipment. We believe all our Mexican open-pit segment equipment is in good physical condition and suitable for our operations.

Buenavista

The Buenavista mining unit operates an open-pit copper mine, two concentrators and three SX-EW plants. It is located 100 air-kilometers northwest of La Caridad and 40 kilometers south of the Arizona, U.S. - Mexican border, at an altitude of 1,900 meters above sea level. It lies on the outskirts of the city of Cananea. Buenavista is connected by paved highways to the border city of Agua Prieta to the northeast, to the town of Nacozari in the southeast and to the town of

42

Table of Contents

Imuris to the west. Buenavista is also connected by railway to Agua Prieta and Nogales. A municipal airport is located approximately 20 kilometers to the northeast of Buenavista.

In 2016 we concluded our $3.5 billion investment program in Mexico. The program included a third SX-EW plant, which was completed in June 2014 with a rated annual capacity of 120,000 tons of copper and a new concentrator, completed in 2015, with an annual copper production capacity of 188,000 tons. The program also included two molybdenum plants with a combined annual capacity of 4,600 tons. The first plant was completed in 2013 and the second in 2016. Additionally, the program included the Crushing, Conveying and Spreading System for Leachable Ore (Quebalix IV), which was completed on time and under budget and is currently operating steadily. This project will reduce mining costs and increase SX-EW copper recovery, allowing the Buenavista unit to reach its copper production capacity of 500,000 tons.

The original concentrator currently has a nominal milling capacity of 82,000 tons per day. The second concentrator began operations in 2015 with a nominal milling capacity of 100,000 tons per day. The SX-EW facilities have a cathode production capacity of 174,470 tons per year. The Buenavista ore body is considered one of the world’s largest porphyry copper deposits. Buenavista is the oldest continuously operated copper mine in North America, with operations dating back to 1899. High grade ore deposits in the district were mined exclusively using underground methods. The Anaconda Company acquired the property in 1917. In the early 1940s, Anaconda started developing the first open-pit in Buenavista. In 1990, through a public auction procedure, Minera Mexico acquired 100% of the Buenavista mining assets for $475 million. Buenavista is currently applying conventional open-pit mining methods to extract copper ore for further processing in the concentrator.

Geology

The Buenavista mining district lies on the southern cordilleran orogen, which extends from southern Mexico to northwestern United States. It also falls within the Basin and Range metallogenic province. Geological and structural features in the district are representative of large, disseminated-type porphyry copper deposits. A calcareous sedimentary sequence of lower Paleozoic age, which is lithologically correlated with a similar section in southeastern Arizona, uncomformably overlies Precambrian granite basement. The entire section was covered by volcanic rocks from the Mesozoic age and later and is intruded by deep seated granodiorite batholith from the Tertiary age, with further quartz monzonite porphyry differentiates from the Laramide age.

Mineralization in the district is extensive, covering a surface area of approximately 30 square kilometers. An early pegmatitic stage associated with bornite-chalcopyrite-molybdenite assemblage was followed by widespread flooding of hydrothermal solutions with quartz-pyrite-chalcopyrite. A pervasive quartz-sericite alteration is evident throughout the district’s igneous rock fabric.

An extensive and economically important zone of supergene enrichment, with disseminated and stockworks of chalcocite (Cu2S), developed below the iron oxide capping. This zone coincides with the topography and has an average thickness of 300 meters. A mixed zone of secondary and primary sulfides underlay the chalcocite blanket. The hypogene mineralization, principally chalcopyrite (CuFeS2), extensively underlies the ore body. Molybdenite occurs throughout the deposit and the content tends to increase with depth.

The Buenavista copper porphyry is considered world-class and unique. The deepest exploration results in the core of the deposit have confirmed a significant increase in copper grades. Similar porphyry copper deposits usually contain lower grades at depth. The district is also unique due to the occurrence of high-grade breccia pipes, which occur in clusters following the trend of the district.

Current dimensions of the mineralized ore body are 5x3 kilometers, and projects to more than one kilometer at depth. Given the geological and economic potential of the Buenavista porphyry copper deposit, it is expected that the operation can support a sizeable increase in copper production capacity.

Mine Exploration

In-fill core drilling was conducted in 2011 at the Buenavista zinc-copper-silver deposit, including directional drilling for geotechnical purposes. A deep drilling campaign was initiated in 2011 to explore the extent of the deposit at depth, drilling a total of 3,860 meters in 2012. For short-term mine planning, 6,652 meters were drilled to confirm copper grade and metallurgical recoveries. Also in 2011, a condemnation drilling program was initiated to define areas for future infrastructure, and for leach and waste dump deposits. A total of 28,369 meters of core drilling were completed in 2011. Additionally, a geohydrology program was initiated in 2011 to explore the possibility of groundwater sources within the mine limits, and a total of 29,750 meters of diamond drilling were drilled in 2012. In addition, 3,797 meters were drilled for water monitoring wells. We did not conduct a drilling campaign in 2013. In 2014, we performed a drilling program of 20,000 meters in order to verify the reserves. In 2015, we complied with our drilling program target of 15,000 meters to define reserves and to confirm copper and molybdenum grades. In 2018, we drilled 4,434 meters to further define reserves and confirm grades. In 2019, in accordance with the long-term mine plan, 5,549 meters of diamond drilling were drilled to confirm the continuity of the deposit mineralization. In 2020, we drilled 32,218 meters in accordance with the mine plan.

Concentrator

Buenavista uses state-of-the-art computer monitoring systems at the concentrators, the crushing plant and the flotation circuit in order to coordinate inflows and optimize operations. In the original concentrator, material with a copper grade over 0.38% is loaded onto trucks and sent to the milling circuit, where giant rotating crushers reduce the size of the ore to approximately one-half of an inch. The ore is then sent to the ball mills, which grind it to the consistency of fine powder. The finely ground powder is agitated in a water and reagents solution and is then transported to flotation cells. Air is pumped into the cells producing a froth, which carries the copper mineral to the surface but not the waste rock, or

44

Table of Contents

tailings. Recovered copper, with the consistency of froth, is filtered and dried to produce copper concentrates with an average copper content of approximately 24%. Concentrates are then shipped by rail to the smelter at La Caridad.

In the second concentrator, material with a copper grade over 0.555% is sent to a three-phase milling circuit, where the ore size is reduced to approximately one-half inch. The ore is then sent to a circuit of six ball mills, which grind it to the consistency of fine powder. The finely ground powder is agitated in a water and reagents solution and is then transported to flotation cells. Air is pumped into the cells producing a froth, which carries the copper mineral to the surface but not the waste rock, or tailings. Recovered copper, with the consistency of froth, is filtered and dried to produce copper concentrates with an average copper content of approximately 24%. Concentrates are then sent by trucks or by railroad to the La Caridad smelter or to the Guaymas port, at Sonora, for export.

As part of the expansion program for this unit, in 2013 we completed the construction of the first molybdenum plant with an annual production capacity of 2,000 tons of molybdenum contained in concentrate. The plant was designed to process 1,500 tons of copper-molybdenum concentrates per day with a content recovery of approximately 80% copper and 50% molybdenum. The molybdenum plant consists of thickeners, homogenizer tanks, flotation cells, column cells and a holo-flite dryer. The second molybdenum plant was designed to process 3,040 tons of copper-molybdenum concentrates per day for a content recovery between 80% and 87% for copper and 60% for molybdenum. The plant generated its first production lot in July 2016 and fully initiated operations in November 2016.

SX-EW Plant

The Buenavista unit operates a leaching facility and three SX-EW plants. All copper ore with a grade lower than the mill cut-off grade of 0.38%, but higher than 0.25%, is delivered to the leach dumps. A cycle of leaching and resting occurs for approximately five years in the run-of-mine dumps and three years for the crushed leach material.

There are three irrigation systems for the dumps and eleven dams for the pregnant leach solution (PLS). Plant I has four solvent extraction tanks with a nominal capacity of 18,000 liters per minute of PLS and 54 electrowinning cells and has a daily production capacity of 30 tons of copper cathodes with 99.999% purity. Plant II has five trains of solvent extraction with a nominal capacity of 62,000 liters per minute of PLS and 220 cells distributed in two bays and has a daily production capacity of 120 tons of copper cathodes with 99.9% purity. Plant III has three trains of solvent extraction with a nominal capacity of 167,100 liters per minute of PLS and 270 cells distributed in two bays and has a daily production capacity of 328 tons of copper cathodes with 99.9% purity. The plant produces copper cathodes of LME grade A.

La Caridad

The La Caridad complex includes an open-pit mine, concentrator, smelter, copper refinery, precious metals refinery, rod plant, SX-EW plant, lime plant and two sulfuric acid plants.

La Caridad mine and mill are located about 23 kilometers southeast of the town of Nacozari in northeastern Sonora at an altitude of 2,000 meters above sea level. Nacozari is about 264 kilometers northeast of the Sonora state capital of Hermosillo and 121 kilometers south of the U.S.—Mexico border. Nacozari is connected by paved highway with Hermosillo and Agua Prieta and by rail with the international port of Guaymas, and the Mexican and United States rail systems. An airstrip with a reported runway length of 2,500 meters is located 36 kilometers north of Nacozari, less than one kilometer away from the La Caridad copper smelter and refinery. The smelter and the sulfuric acid plants, as well as the refineries and rod plant, are located approximately 24 kilometers from the mine. Access is by paved highway and by railroad.

The concentrator began operations in 1979; the molybdenum plant was added in 1982 and the smelter in 1986; the first sulfuric acid plant was added in 1988 and the SX-EW plant in 1995; the second sulfuric acid plant was added in 1997 and the copper refinery in 1997; the rod plant was added in 1998 and the precious metals refinery in 1999; and the dust and effluents plant was incorporated in 2012.

Geology

The La Caridad deposit is a typical porphyry copper and molybdenum deposit, similar to that found in the southwestern basin of United States. The La Caridad mine uses a conventional open-pit mining method. The ore body is at the top of a mountain, which gives La Caridad the advantage of a relatively low waste-stripping ratio, natural pit drainage and relatively short haul for both ore and waste. The mining method involves drilling, blasting, loading and hauling of ore mill to the primary crushers and leach materials and waste to dumps.

La Caridad deposit is located in northeastern Sonora, Mexico. The deposit is situated near the crest of the Sierra Juriquipa, about 23 kilometers southeast of the town of Nacozari, Sonora, Mexico. The Sierra Juriquipa rises to elevations of around 2,000 meters in the vicinity of La Caridad and is one of the many north-trending mountain ranges in Sonora that form a southern extension of the basin and range province.

The La Caridad porphyry copper-molybdenum deposit occurs exclusively in felsic to intermediate intrusive igneous rocks and associated breccias. Host rocks include diorite and granodiorite. These rocks are intruded by a quartz monzonite porphyry stock and by numerous breccia masses, which contain fragments of all the older rock types.

Supergene enrichment consists of complete to partial chalcosite (Cu2S) replacement of chalcopyrite (CuFeS2). The zone of supergene enrichment occurs as a flat and tabular blanket with an average diameter of 1,700 meters and thickness generally between 0 and 90 meters.

Economic ore is found as disseminated sulfurs within the central part of the deposit. Sulfide-filled breccia cavities are most abundant in the intrusive breccia. This breccia-cavity mineralization occurs as sulfide aggregates that have

46

Table of Contents

crystallized in the spaces separating breccia clasts. Near the margins of the deposit, mineralization occurs almost exclusively in veinlets. Ore minerals include chalcopyrite (CuFeS2), chalcosite (Cu2S) and molybdenite (MoS2).

Mine Exploration

The La Caridad ore body has been mined for over 35 years. The extent of the model area is approximately 6,000 meters by 4,000 meters with elevations ranging from 750 to 1,800 meters. Seventeen drilling campaigns have been conducted on the property since 1968. These campaigns drilled a total of 3,349 drill holes: 1,186 were diamond drill holes and 2,163 were reverse circulation. We have also drilled some hammer and percussion drill holes.

In 2008, La Caridad finished a large exploration program of 50,000 meters. The target was to reach the 900 level to reduce the drilling space; define the copper and molybdenum mineralization continuity; and carry out metallurgical testing for the flotation and leaching processes. There was no exploration program in 2009, 2011 and 2013. In 2012, we drilled 10,000 meters and further defined the extent of copper and molybdenum mineralization. From 2014 to 2017 we drilled 96 diamond drill holes equivalent to 38,984 meters to define a high-grade ore body located on the south western edge of the pit (Bella Union location). In 2018, we drilled 18 diamond drill holes equivalent to 5,132 meters at the Bella Union location. In 2019, we drilled 15 diamond drill holes at the La Caridad pit and 6 diamond drill holes at the Bella Union location, for a total of 3,790 meters. In 2020, we drilled 44 diamond drill holes at the La Caridad pit for a total of 9,453 meters.

Concentrator

La Caridad uses state-of-the-art computer monitoring systems at the concentrator, the crushing plant and the flotation circuit to coordinate inflows and optimize operations. The concentrator has a current capacity of 94,500 tons of ore per day.

Ore extracted from the mine with a copper grade over 0.30% is sent to the concentrator and processed into copper concentrates and molybdenum concentrates. The copper concentrates are sent to the smelter and the molybdenum concentrate is sold to a Mexican customer. The molybdenum recovery plant has a capacity of 2,000 tons per day of copper-molybdenum concentrates. The lime plant has a capacity of 340 tons of finished product per day.

SX-EW Plant

Approximately 919.7 million tons of leaching ore with an average grade of approximately 0.241% copper was extracted from the La Caridad open-pit mine and deposited in leaching dumps through December 31, 2020. All copper ore with a grade lower than the mill cut-off grade 0.30%, but higher than 0.15% copper, is delivered to the leaching dumps. In 1995, we completed the construction of a SX-EW facility at La Caridad that has allowed us to process this ore and certain leach ore reserves that were not mined; this has led to a subsequent reduction in our copper production costs. The SX-EW facility has an annual design capacity of 21,900 tons of copper cathodes.

The plant has three trains of solvent extraction with a nominal capacity of 2,400 cubic meters per hour and has 94 electrowinning cells, which are distributed in a single electrolytic bay. The plant has a daily production capacity of 65 tons of copper cathodes with 99.999% purity.

Processing Facilities—La Caridad

Our La Caridad complex includes a smelter, an electrolytic copper refinery, a precious metal refinery, a copper rod plant and an effluent and dust treatment plant. The distance between this complex and the La Caridad mine is approximately 24 kilometers.

Smelter

Copper concentrates from Buenavista, Santa Barbara, Charcas and La Caridad are transported by rail and truck to the La Caridad smelter where they are processed and cast into copper anodes of 99.2% purity. Sulfur dioxide off-gases

47

Table of Contents

collected from the flash furnace, the El Teniente converter and conventional converters are processed into sulfuric acid at two sulfuric acid plants. Approximately 2% to 3% of this acid is used by our SX-EW plants and the balance is sold to third parties.

All of the anodes produced in the smelter are sent to the La Caridad copper refinery. The actual installed capacity of the smelter is 1,000,000 tons per year, a capacity that is sufficient to treat all the concentrates of La Caridad and almost 40.5% of total production of the OMIMSA I and OMIMSA II concentrators from Buenavista. In 2010, the smelter also began processing concentrates from the IMMSA mines, as we closed the San Luis Potosi smelter.

Other facilities in the smelter include two sulfuric acid plants with capacities of 2,625 and 2,135 tons per day, three oxygen plants each with a production capacity of 275 tons per day; and one power turbine which generates 11.5 MWh.

Refinery

La Caridad includes an electrolytic copper refinery that uses permanent cathode technology. The installed capacity of the refinery is 300,000 tons per year. The refinery consists of an anode plant with a preparation area, an electrolytic plant with an electrolytic cell house with 1,115 cells and 32 liberator cells, two cathode stripping machines, an anode washing machine, a slime treatment plant and a number of ancillary installations. The refinery is producing grade A (LME) and grade 1 (COMEX) copper cathode of 99.99% purity. Anodic slimes are recovered from the refining process and sent to the slime treatment plant, where additional copper is extracted. The slimes are then filtered, dried, packed and shipped to the La Caridad precious metals refinery to produce silver and gold.

Precious Metals Plant

The operations at the precious metal refinery begin with the reception of anodic slimes, which are dried in a steam dryer. After this, the dried slime is smelted and a gold and silver alloy is obtained, which is known as Dore. The precious metal refinery plant has a hydrometallurgical stage and a pyrometallurgical stage, in addition to a steam dryer, Dore casting system, Kaldo furnace, 20 electrolytic cells in the silver refinery, one induction furnace for fine silver, one silver ingot casting system and two reactors for obtaining fine gold. The process ends with the refining of the gold and silver alloy. We also recover commercial selenium from the gas produced by the Kaldo furnace process.

Copper Rod Plant

A rod plant at the La Caridad complex began operations in 1998 and reached its full annual operating capacity of 150,000 tons in 1999. The plant is producing eight-millimeter copper rods with a purity of 99.99%.

Effluent and Dust Treatment Plant

In 2012, we started operating a dust and effluent plant with a treatment capacity of 5,000 tons of smelter dusts per year, which will produce 1,500 tons of copper by-products and 2,500 tons of lead sulfates per year. This plant is designed to reduce dust emissions from La Caridad metallurgical complex.

(*)

Weighted average annual operating days based on total material mined and milled in the four active mines: Charcas, Santa Barbara, Santa Eulalia and San Martin.

Charcas

The Charcas mining complex is located 111 kilometers north of the city of San Luis Potosi in the State of San Luis Potosi, Mexico. Charcas is connected to the state capital by a paved highway of 130 kilometers. It was discovered in 1573 and operations in the 20th century began in 1911. The complex includes three underground mines (San Bartolo, Rey-Reina and La Aurora) and one flotation plant that produces zinc, lead and copper concentrates with significant amounts of silver. The Charcas mine is characterized by low operating costs and good quality ores and is situated near the zinc refinery. Regarding its geology, economic ore is found as replacement sulfurs in carbonates host rock. The ore mineralogy is comprised predominantly of calcopyrite (CuFeS2), sphalerite (ZnS), galena (PbS) and silver minerals as diaphorite (Pb2Ag3Sb3S8). The Charcas mine is now Mexico’s largest producer of zinc.

In October 2015, an earthquake damaged some underground facilities as well as the access to the mine. Consequently, normal mine operations were interrupted. In 2016, operations took place normally and a production compliance level of 97% was reached.

Mine exploration in 2015 included 32,144 meters of surface drilling and 20,536 meters from underground stations, which increased our reserves by 3,089,797 tons. For 2016, it included 20,000 meters of surface drilling and 20,754 meters from underground stations, which increased our reserves by 1,778,728 tons. For 2017, it included 5,999 meters of surface drilling and 23,098 meters from underground stations, which increased our reserves by 2,004,577 tons. For 2018, 11,757 meters of diamond drilling and 20,285 meters from underground stations were drilled, which increased our reserves by 2,282,322 tons. For 2019, 20,105 meters of diamond drilling and 9,012 meters from

50

Table of Contents

underground stations were drilled, which increased our reserves by 2,502,204 tons. In 2020, we drilled 10,609 meters from underground stations, which increased our reserves by 2,356,499 tons. For 2021, 15,364 meters of diamond drilling are planned to identify additional reserves.

Santa Barbara

The Santa Barbara mining complex is located approximately 26 kilometers southwest of the city of Hidalgo del Parral in southern Chihuahua, Mexico. The area can be reached via paved road from Hidalgo del Parral, a city on a federal highway. It was discovered in 1536 and mining activities in the 20th century began in 1913. Santa Barbara includes three main underground mines (San Diego, Segovedad and Tecolotes) as well as a flotation plant and produces lead, copper and zinc concentrates, with significant amounts of silver.

Regarding its geology, economic ore minerals include sphalerite (ZnS), marmatite (ZnFeS), galena (PbS), chalcopyrite (CuFeS2) and tetrahedrite (CuFe12Sb4S13). Due to the variable characteristics of the ore bodies, four types of mining methods are used: shrinkage stoping, long-hole drilled open stoping, cut-and-fill stoping and horizontal bench stoping. The ore, once crushed, is processed in the flotation plant to produce concentrates.

Mine exploration in 2015 included 5,977 meters of surface drilling and 16,609 meters from underground stations, which increased our reserves by 1,135,750 tons. For 2016, it included 14,300 meters from underground stations, which increased our reserves by 1,416,756 tons. For 2017, it included 2,571 meters of surface drilling and 11,838 meters from underground stations, which increased our reserves by 613,872 tons. For 2018, 10,769 meters from underground stations were drilled, which increased our reserves by 418,345 tons. For 2019, we achieved 11,070 meters of surface drilling and 208 meters from the underground stations, which increased our reserves by 2,160,062 tons. In 2020, we drilled 19,873 meters from underground stations, which increased our reserves by 2,606,888 tons. For 2021, 37,110 meters of diamond drilling are planned to identify additional reserves.

Santa Eulalia

The mining district of Santa Eulalia is located in the central part of the state of Chihuahua, Mexico, approximately 26 kilometers east of the city of Chihuahua, and is connected to the city of Chihuahua by a paved road (highway no. 45). It was discovered in 1590 but exploitation began in 1870. The main mines in Santa Eulalia are The Buena Tierra mine and the San Antonio mine.

Regarding its geology, the majority of mineralization corresponds to ore skarns: silicoaluminates of calcium, iron and manganese with variable quantities of lead, zinc, copper and iron sulfides. Economic ore include sphalerite (ZnS), galena (PbS) and small quantities of pyrargyrite (Ag3SbS3).

Mine exploration in 2015 included 3,014 meters from underground stations, which increased our reserves by 64,800 tons. In 2017, exploration included 936 meters from underground stations, which increased our reserves by 60,525 tons. In 2018, 1,930 meters from underground stations were drilled, which increased our reserves by 249,930 tons. In 2019, we achieved 2,207 meters of surface drilling and 10,214 meters from the underground stations, which increased our reserves by 409,733 tons.

In the first quarter of 2020, the Santa Eulalia mine temporarily suspended its operations due to flooding. We are currently evaluating different options to supply the Santa Eulalia concentrator. We are also evaluating drainage at the mining facilities and determining if it is possible to sell the water for agricultural or other uses.

San Martin

The San Martin mining complex is located in the municipality of Sombrerete in the western part of the state of Zacatecas, Mexico. It was discovered in 1555 and mining operations in the 20th century began in 1949. The complex includes an underground mine and a flotation plant. The ore body contains lead, copper and zinc concentrates, with significant amounts of silver.

Table of Contents

After eleven years of an illegal stoppage, we resumed control of the San Martin mine in August 2018. The San Martin facilities deteriorated during this period and we undertook a major renovation to restart operations in the second quarter of 2019, with a capital budget of $97.7 million. Production at this mine was restored to full capacity at the end of the third quarter of 2019.

Mine exploration in 2019 included 1,304 meters of surface drilling and 4,315 meters from underground stations, which increased our reserves by 374,683 tons. In 2020, we drilled 5,414 meters from underground stations, which increased our reserves by 519,761 tons. For 2021, 10,851 meters of diamond drilling are planned to identify additional reserves.

Taxco

The Taxco mining complex has been on strike since July 2007. It is located on the outskirts of the city of Taxco in the northern part of the state of Guerrero, Mexico. It was discovered in 1519 and mining activities in the 20th century began in 1918. The complex includes several underground mines (San Antonio, Guerrero and Remedios) and a flotation plant. The ore contains lead and zinc concentrates, with some amounts of gold and silver.

There was no mine exploration drilling at Taxco during the three-year period ended December 31, 2020 due to the strikes. Please see Note 13 “Commitments and Contingencies—Labor matters” to the consolidated financial statements.

Processing Facilities—San Luis Potosi

Our San Luis Potosi electrolytic zinc refinery is located in the city of San Luis Potosi, in the state of San Luis Potosi, Mexico. The city of San Luis Potosi is connected to our refinery by a major highway.

Zinc Refinery

The San Luis Potosi electrolytic zinc refinery was built in 1982 and was designed to produce 105,000 tons of refined zinc per year by treating up to 200,000 tons of zinc concentrate from our own mines, principally Charcas, which is located 113 kilometers from the refinery. The refinery produces special high-grade zinc (99.995%), high-grade zinc (over 99.9%) and zinc-based alloys with aluminum, lead, copper or magnesium in varying quantities and sizes depending on market demand. Refined silver and gold production is obtained from tolling services provided by a third party mining company.

The electrolytic zinc refinery has an acid plant, a steam recovery boiler and a roaster. There is also a calcine processing area with five leaching stages: neutral, hot acid, intermediate acid, acid, purified fourth and jarosite, as well as two stages for solution purifying.

Nueva Rosita Coal and Coke Complex

The Nueva Rosita coal and coke complex began operations in 1924 and is located in the state of Coahuila, Mexico, on the outskirts of the city of Nueva Rosita near the Texas border. It includes (a) an underground coal mine, which has been

52

Table of Contents

closed since 2006; (b) an open-pit mine with a yearly capacity of approximately 350,000 tons of coal; (c) a coal washing plant with a capacity of 900,000 tons per year that produces high quality clean coal; and d) a re-engineered and modernized 21 ovens coke facility capable of producing 100,000 tons of coke per year (metallurgical, nut and fine) of which, 95,000 tons are metallurgical coke. The complex also has a by-product plant to clean the coke gas oven in which tar, ammonium sulfate and light crude oil are recovered and two boilers, which produce 80,000 pounds of steam that is used in the by-products plant. In September 2017, a decision was made by the Company to close the coke plant and to initiate the cleaning and remediation process with a current budget of $14.0 million. As of December 31, 2020, expenses totaled $6.4 million.

On February 19, 2020, the Company announced the decision to return the underground coal mine, (the Olivo concession), which had been closed since 2006, to the Mexican government in response to a request of the President of Mexico to resume efforts to locate the remains of miners lost in a 2006 mining accident. On February 20, 2020 the Company presented the offer to return the concession to the General Direction of Mines. On September 3, 2020, the authorities accepted the offer.

Carbon mine exploration

Although, an intensive diamond drilling exploration program has identified two additional areas, Esperanza with a potential for more than 30 million tons of “in place” mineralized coal and Guayacan with a potential for 15 million tons of “in place” mineralized coal, all of which could be used for a future coal-fired power plant; in July 2019, the Company decided to suspend coal mining operations.

ORE RESERVES

Ore reserves are the estimated quantities of proven and probable material that may be economically mined and processed for extraction of their mineral content at the time of reserve determination. “Proven” (measured) reserves are reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; (b) grade and/or quality are computed from the results of detailed samplings; and (c) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well-established. “Probable” (indicated) reserves are reserves for which quantity and grade and/or quality are computed from information similar to that used for proven (measured) reserves, but the sites for inspection, sampling, and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven (measured) reserves, is high enough to assume continuity between points of observation. “Mineralized material,” on the other hand, is a mineralized body that has been delineated by appropriately spaced drilling and/or underground sampling to support the reported tonnage and average grade of metal(s). Such a deposit does not qualify as a reserve until legal and economic feasibility are concluded based upon a comprehensive evaluation of unit costs, grade, recoveries and other material factors.

Our proven and probable ore reserve estimates are based on engineering evaluations of assay values derived from the sampling of drill holes and other openings. We believe that the samplings taken are spaced at intervals close enough and

53

Table of Contents

the geological characteristics of the deposits are sufficiently well defined to render the estimates reliable. The ore reserve estimates include assessments of the resource, mining and metallurgy, as well as economic, marketing, legal, environmental, governmental, social and other necessary considerations.

Our Peruvian operations, including the Toquepala and Cuajone reserves, are classified into proven (measured), probable (indicated) and possible (inferred) categories based on a Relative Confidence Bound Index (“RCB Index”) that measures our level of geologic knowledge and confidence in each block. The RCB index is a measure of relative confidence in the block grade estimate. This approach combines the local variability of the composites used to krig a block with the kriging variance and incorporates the use of confidence intervals in measuring uncertainty of the block estimates relative to each other. The final resource classification is then based on the distribution of these RCB values for blocks above 0.05% copper. It is the distribution that is used to find the breaks between proven/probable and probable/possible.

Our Mexican operations, including the Buenavista and La Caridad reserves, are calculated using a mathematical block model and applying the MineSight software system. The estimated grades per block are classified as proven and probable. These grades are calculated applying a three-dimensional interpolation procedure and the inverse distance squared. Likewise, the quadrant method or spherical search is implemented to limit the number of composites that will affect the block’s interpolated value. The composites data is derived from the geological exploration of the ore body. In order to classify the individual blocks in the model, a thorough geostatistical variogram analysis is conducted, taking into consideration the principal characteristics of the deposit. Based on this block model classification, and with the implementation of the Lerch-Grossman algorithm, and the MineSight Pit Optimizer procedure, mineable reserves are determined. The calculated proven and probable reserves include those blocks that are economically feasible to mine by open-pit method within a particular mine design.

For the IMMSA unit, the basis for reserve estimations are sampling of mining operations and drilling exploration, geographical and topographic surveys, tracking down all the foregoing in the corresponding maps, measurement, calculation and interpretation based on the maps and reports from the mines, the mills and/or smelters. Mineral reserves are mineral stock which is estimated for extraction, to exploit if necessary, to sell or utilize economically, all or in part, taking into consideration the quotations, subsidies, costs, availability of treatment plants and other conditions that we estimate will prevail in the period for which reserves are being calculated. The reserves are divided into proven (85% reliable or more according to statistical studies) and probable (70% - 80% reliable or more according to statistical studies) categories according to their level of reliability and availability. In order to comply with SEC regulations, proven reserves is a classification that can only be used for such mineral found on top of the last level of the mine (either mineral up to 15 meters below the last level or below the first 15 meters only with sufficient drilling (25 or 30 meters between each drill)).

Our engineering department reviews reserve computations in detail on an annual basis. In addition, our engineering department reviews the computation when changes in assumptions occur. Changes can occur for price or cost assumptions, results in field drilling or new geotechnical parameters. We also engage third party consultants to review mine planning procedures.

Pursuant to SEC guidance, the reserves information in this report are calculated using average metals prices over the most recent three years unless otherwise stated. We refer to these three-year average metals prices as “current prices.” Our current prices for copper are calculated using prices quoted by COMEX, and our current prices for molybdenum are calculated according to Platt’s Metals Week. Unless otherwise stated, the reserve estimates in this report use $2.82 per pound for copper and $10.66 per pound for molybdenum, both current prices as of December 31, 2020. The current prices for copper and molybdenum were $2.82 and $10.50 as of December 31, 2019 and $2.64 and $8.88 as of December 31, 2018, respectively.

For internal ore reserve estimation, our management uses long-term metal price assumptions for copper and molybdenum, which are intended to approximate average prices over the long term. As of December 31, 2020, we considered $3.00 per pound of copper and $9.00 per pound of molybdenum. As of December 31, 2019, we considered $2.90 per pound of copper and $7.50 per pound of molybdenum.

The average metal prices over the last 10 and 15-year periods and the continued positive outlook for these metals have led us to use these prices. For other forecast and planning purposes, particularly related to merger and acquisition activities, our management considers other price scenarios. These changes, however, do not affect the preparation of our financial statements.

For the years 2020, 2019 and 2018, we have used reserve estimates based on current average prices for the most recent three years then ended to determine amortization of mine development and intangible assets.

We periodically reevaluate estimates of our ore reserves, which represent our estimate as to the amount of unmined copper remaining in our existing mine locations that can be produced and sold at a profit. These estimates are based on engineering evaluations derived from samples of drill holes and other openings, combined with assumptions about copper market prices and production costs at each of our mines.

The persons responsible for ore reserve calculations are as follows:

Peruvian open-pit:

Cuajone mine – Julio Sagua Canqui, Mine Engineering Superintendent

Toquepala mine - Wilbert Perez, Mine Engineering Superintendent

Tia Maria project:

Jaime Arana Murriel, Investment Projects Leaching Manager

On October 31, 2018, the SEC adopted new technical disclosure requirements applicable to companies engaged in material mining operations, including royalty companies. These new rules are based on the Committee for Mineral Reserves International Reporting Standards (CRIRSCO) and will replace the SEC Industry Guide 7. The new rules are effective for the fiscal year beginning on or after January 1, 2021. The Company has designed an implementation plan and formed a cross-functional implementation team that include external mining experts as required by the rule. This team is performing a completeness assessment of the Company’s mining operations to establish new policies, procedures and internal controls as mandated by the new standard.

For more information regarding our reserve estimates, please see Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates—Ore Reserves.”

Metal Price Sensitivity:

In preparing the sensitivity analysis, we recalculated our reserves based on the assumption that current average metal prices were 20% higher and 20% lower, respectively, than the actual current average prices for year-end 2020. Reserve results of this sensitivity analysis are not proportional to the increase or decrease in metal price assumptions.

Internal Ore Reserves Estimates:

The table below provides details on our proven and probable copper and molybdenum reserves as of December 31, 2020, which are estimated based on long-term price assumptions of $3.00 per pound of copper, $9.00 per pound of molybdenum and $19.00 per ounce of silver. As discussed on page 54, the internal ore reserve estimates as presented are not compliant with SEC requirements, given that long-term price assumptions differ from the current prices used pursuant to SEC guidance. These internal ore reserve estimates do not affect the preparation of our financial statements.

OVERVIEW OF BLOCK MODEL RECONCILIATION PROCESS

We apply the following block model to mill reconciliation procedure.

The following stages are identified at the Cuajone, Toquepala, Buenavista and La Caridad mines:

1.The mine geologists gather the necessary monthly statistical data from our information system (“SRP”), which provides ore tons milled and ore grades in the concentrator.
2.Mined areas are topographically determined and related boundaries are built.
3.Using the “interactive planner” option in our mining software (MineSight), ore tons and grades are calculated inside mined areas over the block model. At this point the current cut-off grade is considered.
4.In the final stage, accumulated tons mined, weighted average grade for ore material and leach is compared to data coming from our SRP system.

Tonnage and grade reconciliation for 2020 are as follows:

EXPLORATION ACTIVITIES

We are engaged in ongoing extensive exploration to locate additional ore bodies in Peru, Mexico, Argentina, Ecuador and Chile. We also conduct exploration in the areas of our current mining operations. We invested $32.6 million on exploration programs in 2020, $30.0 million in 2019 and $29.6 million in 2018 and we expect to spend approximately $61.2 million on exploration programs in 2021.

Currently, we directly control 59,252 hectares and 503,104 hectares of exploration concessions in Peru and Mexico, respectively. We also currently hold 229,312 hectares, 27,353 hectares and 7,299 hectares of exploration concessions in Argentina, Chile and Ecuador, respectively.

Peru

Los Chancas. This property, located in the department of Apurimac in southern Peru, is a copper and molybdenum porphyry deposit. Current estimates indicate the presence of 545 million tons of mineralized material with a copper content of 0.59%, molybdenum content of 0.04% and 0.039 grams of gold per ton and 181 million tons of mineralized leachable material with a total copper content of 0.357%. In 2019 and 2020, we developed social and environmental improvements for local communities. In 2021, we plan to continue with these activities and to conclude the environmental impact assessment of the project.

Michiquillay. This property, located in the district of La Encañada, in the province and department of Cajamarca in northern Peru, is a copper porphyry deposit. In February 2018, we won the public bidding process for the project, and in June 2018 we signed the acquisition contract with the Peruvian government. In 2019, we developed social and environmental programs for the local communities and in 2020, we are concluding the semi-detailed environmental impact assessment. This will allow us to begin a 50,000-meter diamond drilling program in 2021 to verify and update the estimated mineralized materials of the project. We also plan to continue developing social programs for the local communities.

Other Peruvian Prospects. In 2020, we drilled 547 meters to complete a 13,000-meter diamond drilling program to explore various geochemical and geophysical anomalies. The results obtained indicate an iron system with low contents of disseminated copper.

For 2021, we plan to conduct a diamond drilling program of 15,500 meters at four prospects in southern Peru that have shown evidence of copper porphyry deposits. Additionally, we will continue conducting several prospection programs at other Peruvian metallogenic zones, which were identified in 2020.

Mexico

In addition to exploration and drilling programs at existing mines, we are currently conducting exploration to locate mineral deposits at various other sites in Mexico. The following are some of the more significant exploration projects:

Buenavista-Zinc. The Buenavista-Zinc site is located in the state of Sonora, Mexico and is part of the northwest Buenavista ore body. It is a skarn deposit containing zinc, copper, silver and lead sulfide mineralization. The deposit contains approximately 102.6 million tons of mineralized material, containing 1.88% of zinc, 0.47% of copper and 17 grams of silver per ton. In 2016, we reviewed the geological model of the deposit and the lithological description of prior drill holes, which were analyzed using infrared spectrometry. The results were included in the reserves database. Currently, we have concluded the conceptual design of the flotation plant. Additionally, the mining plan and economic studies have been prepared by external companies. In 2020, exploration was concluded at the Buenavista-Zinc site. In 2021, we expect to conduct a 5,000-meter drilling program at the Elisa-Puertecitos project, which is immediately northeast of Buenavista-Zinc.

The Chalchihuites. This is a skarn type deposit located in the state of Zacatecas, close to the San Martin mining unit. Drilling programs conducted between 1980 and 2014 identified 12.6 million of mineralized material with an average silver content of 110 grams per ton, 2.66% of zinc, 0.37% of lead and 0.67% of copper. Current results indicate that mineralization consists of a complex mixture of oxides and sulfides of silver, lead and zinc that requires additional metallurgical research. In 2017, we started a new drilling program of 21,000 meters to continue metallurgical research and testing. In 2018, this exploration program, which included 48 drill holes was completed. This program has been carried out in compliance with QA/QC protocol, which includes testing the specific density of different rocks and mineralized types and geochemistry sampling. In addition, 5,000 meters of core sample from the drilling program were analyzed with a hyperspectral scanner, and a study of 498 kilometers of hyperspectral imaging was conducted to recognize the geology of the entire Chalchihuites mineral district. In 2019, with the complete data from the diamond drilling program, we made a geological model of the Cronos deposit using Leapfrog software. In 2020, the sample design for a metallurgical test was completed and three metallurgical samples were delivered to an external consultant. We expect to conduct this test in 2021.

Bella Union (La Caridad). This prospect is a mineralized copper and molybdenum breccia deposit; the site is located at less than one kilometer from the border of La Caridad pit. In 2016 and 2017, we conducted a 28,217 meter drilling program to define the geometry of the deposit. The results identified 36.2 million tons of mineralized material with an average of 0.44% copper content and 0.05% of molybdenum. In May 2018, the drilling in this project was completed, totaling 46,400 meters distributed in 113 drill holes. The test results were received in June 2018. Currently, exploration at Bella Union has been completed and external consultants are working to integrate the information of this prospect into the life plan for the La Caridad-Pilares mines.

Campo Medio (Santa Eulalia). This prospect is located close to the west border of the Santa Eulalia mine. Results of geological surveying and drilling programs indicated that its mineralization consists of sulfides with 2.85 meters of width, 219 grams of silver, 6.60% of lead and 7.55% of zinc. Exploration at the Campo Medio area did not render positive results and exploration activities were suspended. In order to continue exploration towards the southern end of the San Antonio mine, the area must be drained because it was affected by flooding at Santa Eulalia.

Chile

El Salado (Montonero). A copper-gold prospect located in the Atacama region, northern Chile has been under exploration for copper and molybdenum porphyry since 2014. In 2016, we conducted a diamond drilling program of 12,169 meters to define mineral classification. In 2017, we drilled a total of 9,939 meters and finished the conceptual study. In 2021, we plan to conduct a pre-feasibility study of the project.

Other Chilean Prospects. In 2020, we concluded exploration work at the Cobre Sol prospect, a copper porphyry prospect located in the Antofagasta region. We conducted three diamond drilling programs, which totaled 798 meters and the results did not meet our objectives. In 2021, we plan to conduct a diamond drilling program of 12,000 meters at three prospects located in the copper-gold strip of the Antofagasta region in the north of Chile.

Ecuador

Chaucha. The Ruta del Cobre (“Copper Road”) project is located west of Cuenca city and south of Guayaquil. The mineralization in this area is characteristic of a copper-molybdenum porphyry system which is being explored since 2014. Through 2019, the exploration phase concluded with a total of 79,900 meters drilled. In 2020, we continued the infill-drilling program, where we conducted 35,400 meters of diamond drilling to reclassify the project’s existing mineralized materials. In 2021, we plan to drill an additional 30,000 meters to conclude the infill-drilling program and begin the project’s feasibility study.

Argentina

In 2011, we started exploration activities in Argentina. In 2015, we performed geological exploration in the Salta, Rio Negro and Neuquen provinces where we expected to locate copper porphyry with precious metals epithermal systems. In 2017, we performed prospection and geological evaluation work in the provinces of San Juan and Rio Negro. In 2019, we conducted a diamond drilling program of 2,530 meters to continue exploring the silver-gold epithermal systems, denominated the Caldera project, located in the Rio Negro province. In 2020, we conducted geological mapping and surface sampling work in these areas. In 2021, we plan to conduct further exploration work, mainly at the Cerro La Mina and Tanque Negro prospects.

Cañadon del Moro. This isa low sulfidation epithermal deposit with high longitude seams located in the Rio Negro province. We have defined an epithermal deposit of silver of potential economic interest with an estimated grade of 9.46 ounces of silver per metric ton. In 2021, we plan to drill an additional 5,000 meters to continue exploring the prospective and potential minerals.

In 2021, we also plan to conduct a diamond drilling program of 4,000 meters at the Esperanza project, located in the Rio Negro province. In addition, in 2021 we plan to conduct exploration programs of 3,000 meters and 2,000 meters at the La Hoyada and La Chilena prospects respectively; both are located in the province of Catamarca.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

EXECUTIVE SUMMARY

This Management’s Discussion and Analysis of Financial Condition and Results of Operations relates to and should be read together with our Audited Consolidated Financial Statements as of and for each of the years in the three-year period ended December 31, 2020. Therefore, unless otherwise noted, the discussion below of our financial condition and results of operations is for Southern Copper Corporation and its subsidiaries (collectively, “SCC,” “Southern Copper,” “the Company,” “our,” and “we”) on a consolidated basis for all periods. Our financial results may not be indicative of our future results.

This discussion contains forward-looking statements that are based on management’s current expectations, estimates and projections about our business and operations. Our actual results may differ materially from those currently anticipated and expressed in the forward-looking statements as a result of a number of factors. See Item 1 “Business—Cautionary Statement.”

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 an active ongoing exploration program in Chile, Argentina and Ecuador.

We believe we hold the world’s largest copper reserve position. As of December 31, 2020, our copper ore reserves, calculated at a copper price of $3.00 per pound, totaled 67.7 million tons of contained copper, at the following locations:

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

Sales structure: In the last three years, approximately 81.0% of our revenues came from the sale of copper, 7.0% from molybdenum, 4.0% from zinc, 5.0% from silver and 3.0% from various other products, including gold, sulfuric acid and other materials.

Copper: In the last quarter of 2020, the LME copper price increased, from an average of $2.67 per pound in the fourth quarter of 2019 to $3.25 (+21.7%). Currently, we are seeing prices over $3.60 per pound, which bodes a positive outlook for the 2021 copper market. We believe the following factors are influencing the market:

A worldwide recovery in copper demand for industrial uses, driven mainly by a sustained recovery in economic activity in China and other Asian economies and in the European auto industry.
Regarding China, it should also be noted that copper scrap imports have decreased by 48% in the last 10 months of 2020, which led to a subsequent increase in Chinese consumption of refined copper.

Table of Contents

The combined inventories of the LME, Comex, Shanghai and Bonded warehouses closed 2020 at their lowest levels since December 2014.

Given the current market outlook for supply and demand, we have a positive view for this year and for the long-term evolution of the copper market.

Molybdenum: It represented approximately 6.4% of our sales in 2020. Molybdenum prices averaged $8.57 per pound in 2020, compared to $11.27 in 2019, a 24.0% decrease.

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

Zinc: Although average zinc prices decreased in 2020 compared with 2019 (-11.0%), we believe zinc has very good long-term fundamentals due to its significant industrial consumption and expected production. Zinc represented 3.1% of our sales in 2020.

Silver: We believe that silver prices will have support due to its industrial uses as well as being perceived as a value shelter in times of economic uncertainty. Silver represented 5.6% of our sales in 2020.

Production: In 2021 and 2022, we expect to produce 943,000 tons of copper given that production during these periods will be affected by a temporary reduction in ore grade and recovery at our Peruvian operations.

We expect our copper production to recover by 2023 and reach 1,031,000 tons of production as we get Peruvian production back on track and generate new production on our Pilares, El Pilar and Buenavista-Zinc Concentrator projects.

We also expect to produce 21.4 million ounces of silver in 2021, in line with 2020 production. In 2021, we expect to produce 76,200 tons of zinc from our mines, up 10.5% from 2020 production level. Additionally, we expect to produce 26,800 tons of molybdenum, which represents a decrease of 11.3% compared to 2020 production levels.

Capital investments: Capital investments were $592.2 million for 2020. This is 16.3% lower than in 2019, and represented 37.7% of net income. Our growth program to develop the full production potential of our Company is underway. We are currently developing a new organic growth plan to increase our copper volume production to 1.9 million tons by 2028 with the development of new projects.

For 2021, the Board of Directors approved a capital investment program of $1,431.3 million.

COVID-19

In March 2020, the World Health Organization classified the COVID-19 outbreak as a pandemic based on a rapid increase in global transmission rates. The full impact of the COVID-19 outbreak will continue and the magnitude of the impact on the Company’s financial condition, liquidity and future operating results is uncertain. Senior management is actively monitoring the global situation´s effect on the Company´s financial condition, liquidity, operations, suppliers, industry and workforce and is focusing principally on the health, safety and well-being of our employees, their families and the communities where we have operations. As of December 31, 2020, there have been no major delays in the supply of the materials and services critical for operations and sales. In addition, the supply of non-critical materials and services for the operations is gradually being restored. Additionally, shipments of products and collections experienced no known major delays in the fourth quarter of 2020.

As of December 31, 2020, we continued to see a positive trend in the copper price, which closed at $3.51 per pound (LME) after it registered a drop to $2.18 per pound at the end of the first quarter of 2020. Considering the market outlook previously described, we have a positive view for 2021 and for the long-term evolution of the copper market.

The Company maintains a solid financial position and performance level. We believe this has allowed and will continue to allow us to deal with the effects of the pandemic in a way that prevents adverse material effects on our operations and financial results.

Governmental authorities in Mexico and Peru have declared that essential economic activities must continue during the COVID-19 health emergency. These activities include industrial mining and/or any other activity necessary to ensure the provision of essential services such as electricity; provide elements to install medical and hospital infrastructure; and manufacture health-related supplies and technological equipment. We believe that industrial mining stands as the most efficient and timely supplier of inputs that are critical to the productive chain to fight the pandemic.

Given the nature of mining operations, which are highly automated, conducted in remote locations and with mandatory use of personal safety equipment at all the mines, it is easier to implement and comply with COVID-19 protective measures, such as physical isolation and control of access to facilities. Industrial mining uses advanced and reliable machinery and does not require high physical concentration of employees. In many cases, workers fulfill their duties maintaining distances of more than 100 meters from their closest coworkers.

At the present time, our operations are in compliance with all sanitary and government regulations and maintain proper environmental safeguards. Our COVID-19 emergency protocol has reinforced preventive measures such as disinfecting, clinical monitoring before work, cleaning and sanitizing of work areas and respect for social distancing. We have also restricted the access of contractors, suppliers and personnel to our facilities if visits are not indispensable and enforced multiple actions to limit workforce exposure to COVID-19 by imposing travel restrictions, prohibiting face-to-face meetings and urging frequent hand washing, as well as adhering to all other health, safety and social distancing measures required by governmental authorities. At December 31, 2020, approximately 92% of the workforce in Mexico was working on site or at home under strict safety measures; the remaining 8% of the workforce was not working, including all individuals at high risk due to age and/or preexisting medical conditions. At our Peruvian operations, approximately 63% of the workforce was working onsite or at home under strict safety measures, while the remaining 37% was not working, including all individuals at high risk due to age and/or preexisting medical conditions. Through December 31, 2020, SCC incurred approximately $27.6 million in COVID-19 related production costs that include protective equipment and labor costs. These costs have been expensed to cost of sales in the Company´s consolidated statement of earnings.

Net sales in 2020 of $8.0 billion were the highest in our history and exceeded those recorded in 2019 by $699.3 million. This increase was mainly the result of higher copper (+6.1%), molybdenum (+12.7%) and silver (+8.8%) sales volumes, as well as higher copper (+2.9%) and silver (+27.6%) prices; this effect was partially offset by lower molybdenum (-24.0%) prices. Net sales in 2019 of $7.3 billion were higher than in 2018 by $188.9 million. This increase was mainly the result of higher copper (+11.3%), molybdenum (+21.7%) and silver (+5.7%) sales volumes and was partially offset by lower copper (−8.1%) and molybdenum (−5.0%) prices.

The two largest components of operating costs and expenses are cost of sales and depreciation, amortization and depletion, both of which increased in each of the years in the periods shown above. In 2020, cost of sales increased by $323.4 million and depreciation, amortization and depletion increased by $11.2 million. The increase in cost of sales in 2020 was mainly due to an increase in the cost of metals purchased from third parties and a decrease in the capitalization of leachable material. This increase was partially offset by a reduction in the cost of diesel and fuel. In 2019, cost of sales increased by $197.4 million and depreciation, amortization and depletion increased by $90.1 million. The increase in cost of sales in 2019 was mainly due to higher repairing materials and operating contractors’ costs, as well as a decrease in capitalized leachable material. This increase was partially offset by a decrease in the cost of metals purchased from third parties.

Net income attributable to SCC in 2020 was 5.7% higher than reported in 2019; this was mainly due to higher sales volumes and to higher copper and silver prices. Net income attributable to SCC in 2019 was 3.6% lower than in 2018; this was primarily driven by a decrease in prices for copper and molybdenum, despite an increase in sales volumes.

2020 compared to 2019:

Copper mine production in 2020 increased 0.8% to 2,207.6 million pounds, up from 2,191.0 million pounds in 2019. This increase was due to:

Higher production at the Cuajone mine (+7.8%), which was driven by an increase in ore grades and recoveries.
Higher production at the La Caridad mine (+1.8%).
Higher production at the IMMSA operations (+24.6%), which was attributable to an increase in ore grades.

Molybdenum production increased 12.5% in 2020 compared to the level in 2019 due to an increase in production at our Toquepala (+37.7%), Cuajone (+28.6%) and La Caridad (+3.2%) operations; this was partially offset by a decrease in production at our Buenavista (-10.6%) mine.

Zinc production decreased 6.8% in 2020, which was driven by a decrease in ore grades and in production at our Santa Eulalia (-96.0%) and Los Charcas (-5.0%) operations; this was partially offset by an increase in production at our San Martin (+151.0%) mine, which restored production to full capacity at the end of the third quarter of 2019.

Mined silver production increased 6.2% in 2020 compared to the level recorded in 2019; this was mainly due to an increase in production at our Cuajone (+8.8%), La Caridad (+16.4%) and IMMSA (+15.0%) operations, which was partially offset by a decrease in production at the Toquepala (-2.4%) and Buenavista (-3.6%) mines.

2019 compared to 2018:

Copper mine production in 2019 increased 12.5% to 2,191.0 million pounds from 1,948.2 million pounds in 2018. This increase was due to:

Higher production at the Toquepala mine (+51.5%), as a result of additional copper production of 93,108 tons from the successful ramping up of the new concentrator.
Higher production at the Buenavista mine (+5.8%) due to operating improvements at our new Buenavista plants, the SX/EW (+12.2%) and concentrator (+4.0%).

73

Table of Contents

Higher production at the IMMSA operations (+32.9%), as result of the restoration of the San Martin mine operations.

Molybdenum production increased 22.3% in 2019 compared to 2018 due to higher production at all of our mines, principally at the Toquepala mine (+75%) due to the successful ramping up of the new molybdenum plant that started production in April 2019.

Zinc production increased 4.4% in 2019, as a result of higher production at our Santa Barbara mine due to higher grades and recoveries, as well as the restored production of 5,837 tons from our San Martin mine.

Mined silver production increased 17.1% in 2019 compared to 2018, mainly due to higher production at our Toquepala (+60.5%), IMMSA (+22.9%) and Buenavista (+11.5%) operations, partially offset by lower production at the La Caridad (-6.6%) and Cuajone (-3.2%) mines.

Operating Cash Costs: An overall benchmark used by us and a common industry metric to measure performance is operating cash costs per pound of copper produced. Operating cash cost is a non-GAAP measure that does not have a standardized meaning and may not be comparable to similarly titled measures provided by other companies. This non-GAAP information should not be considered in isolation or as substitute for measures of performance determined in accordance with GAAP. A reconciliation of our operating cash cost per pound of copper produced to the cost of sales (exclusive of depreciation, amortization and depletion) as presented in the consolidated statement of earnings is presented under the subheading, “Non-GAAP Information Reconciliation” on page 96. 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 will allow our management and stakeholders to see a presentation of 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

74

Table of Contents

the copper industry and is a useful management tool that allows us to track our performance and better allocate our resources. This measure is also used in our investment project evaluation process to determine a project’s potential contribution to our operations, its competitiveness and its relative strength in different price scenarios. The expected contribution of by-products is generally a significant factor used by the copper industry to determine whether to move forward or not in the development of a new mining project. As the price of our by-product commodities can have significant fluctuations from period to period, the value of its contribution to our costs can be volatile.

Our operating cash cost per pound of copper produced, as defined above, is presented in the table below for the three years ended December 31, 2020:

2020 compared to 2019:

As seen in the table above, our per pound cash cost before by-product revenues in 2020 was 9.9% lower than that recorded in 2019. This reduction is mainly attributable to a temporary decrease in production costs, as some operating, stripping and maintenance costs were reduced or postponed due to the COVID-19 pandemic. Our cash cost per pound net of by-product revenues for 2020 was 21.7% below that seen for the same period of 2019 and was also attributable to the temporary decrease in production costs outlined above.

2019 compared to 2018:

As seen in the table above, our per pound cash cost before by-product revenues in 2019 was 1.3% lower when compared with 2018. This decrease was the result of the unit cost effect of 13.1% higher production. Meanwhile, our cash cost per pound when calculated net of by-product revenues for 2019 was 1.1% higher than in the same period of 2018 due to the higher production noted, as well as lower by-product revenues due to the additional copper volume effect.

Metal Prices: The profitability of our operations is dependent on, and our financial performance is significantly affected by, the international market prices for the products we produce, especially for copper, molybdenum, zinc and silver.

We are subject to market risks arising from the volatility of copper and other metals prices. Metal prices historically have been subject to wide fluctuations and are affected by numerous factors beyond our control. These factors, which affect each commodity to varying degrees, include international economic and political conditions, levels of supply and demand, the availability and cost of substitutes, inventory levels maintained by producers and others and, to a lesser degree, inventory carrying costs and currency exchange rates. In addition, the market prices of certain metals have on occasion been subject to rapid short-term changes due to economic concerns and financial investments.

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. Our Mexican open-pit operations include La Caridad and Buenavista mine complexes, the smelting and refining plants and support facilities, which service both mines. Our IMMSA unit includes five underground minesand several industrial processing facilities.

Segment information is included in our review of “Results of Operations” in this item and also in Note 18 “Segment and Related Information” of the 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 and Mexican currency occur, our operating results can be affected. In recent years, we believe these changes have had no material effect on our results and financial position. Please see Item 7A “Quantitative and Qualitative Disclosures about Market Risk” for more detailed information.

Capital Investment Program: We made capital investments of $592.2 million in 2020, $707.5 million in 2019 and $1,121.4 million in 2018. In general, the capital investments and projects described below are intended to increase production, decrease costs or address social and environmental commitments.

In 2021, we plan to invest $1,431.3 million in capital projects. In addition to our ongoing capital maintenance and replacement spending, our principal capital programs include the following:

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 80,000 tons of zinc and 20,000 tons of copper per year. We have completed the basic engineering study and the detailed engineering study has reached 81% completion. In order to continue with the project, stronger preventive measures to combat COVID-19 have been put in place. Purchase orders have been placed for major equipment, some of which is currently being manufactured. The project has all the necessary permits. The project´s budget is $413 million, and we expect to initiate operations in 2023. When completed, we anticipate that this new facility will double the Company’s zinc production capacity and will provide 490 direct jobs and 1,470 indirect jobs.

Pilares - Sonora: This project, located six kilometers from La Caridad, will be developed as an open-pit mine operation with an annual production capacity of 35,000 tons of copper in concentrate. The ore will be transported from the pit to the primary crushers of the La Caridad copper concentrator through a new 25-meter wide off-road facility for mining trucks, which is under construction, and will significantly improve the overall mineral ore grade (combining the 0.78%

77

Table of Contents

expected from Pilares with 0.34% from La Caridad). The budget for Pilares is $159 million and we expect the project to begin production in the first quarter of 2022.

El Pilar - Sonora: This is a low-capital intensity copper development project strategically located in Sonora, Mexico, approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and probable reserves of 281 million tons of ore with an average copper grade of 0.301%. El Pilar will operate as a conventional open-pit mine with an annual production capacity of 36,000 tons of copper cathodes. This operation will use highly cost efficient and environmentally friendly SX-EW technology. We estimate a development investment of approximately $310 million.Construction at the pilot plant and experimental pads has ended and tests are being performed. The results from experimental pads on leaching process have confirmed adequate levels of copper recovery. We expect this project to start production in 2023 with an expected mine life of 13 years.

The San Martin mine recovery program. After eleven years of illegal stoppage, we resumed control of the San Martin mine in August 2018. The San Martin facilities deteriorated during this period but we made a major renovation and restarted operations during the second quarter of 2019. In 2020, we produced 14,361 tons of zinc, 2.8 million ounces of silver, 3,601 tons of copper, and 1,425 tons of lead. The budget for the restoration program is $97.7 million. As of December 31, 2020 the program reported a total expense of $86.4 million.

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 of some facilities due to dam growth and implementation of other facilities for water recovery, among other factors. As of December 31, 2020, the engineering study is complete and we have initiated the procurement process for the necessary materials and equipment. This project has a total budget of $140.0 million, of which we have invested $32 million as of December 31, 2020. Progress on the Project is 41% according to the plan.

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

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

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

This greenfield project, located in Arequipa, Peru, will use state of the art SX-EW technology with the highest international environmental standards. SX-EW facilities are the most environmentally friendly in the industry due to their technical process with no emissions released into the atmosphere. 

Potential projects:

We have a number of other projects that we may develop in the future. We continuously evaluate new projects on the basis of our long-term corporate objectives, strategic and operating fit, expected return on investment, required investment, estimated production, estimated cash-flow profile, social and environmental considerations, among other

78

factors. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy, market conditions or the COVID-19 pandemic.

El Arco - Baja California: This is a world-class copper deposit located in the central part of the Baja California peninsula, with ore reserves of 2.4 billion tons with an ore grade of 0.422%, 0.3 billion tons of leach material with an ore grade of 0.288% and 0.11 grams of gold per ton. This project envisions an open-pit mine with a combined concentrator and SX-EW operations, with an estimated production capacity of 190,000 tons of copper and 105,000 ounces of gold annually. The project has an estimated capital budget of $2.9 billion. The Company has started the baseline study and is reviewing the basic engineering analysis to request the environmental impact permit. We are currently in the final stage of the land acquisition process for the project.

Los Chancas—Apurimac:This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit. Current estimates indicate the presence of 545 million tons of mineralized material with a copper content of 0.59%, molybdenum content of 0.04% and 0.039 grams of gold per ton, as well as 181 million tons of mineralized leachable material with a total copper content of 0.357%. Los Chancas project envisions an open-pit mine with a combined operation of concentrator and SX-EW processes to produce 130,000 tons of copper and 7,500 tons of molybdenum annually. The estimated capital investment is $2,600 million and the project is expected to be in operation in 2027. In 2019, we continued to engage in social and environmental improvements for the local communities. In 2020, we continued to work on these activities and plan to conclude the environmental impact assessment for the project in 2021.

Michiquillay Project—Cajamarca:On June 12, 2018, Southern Copper signed a contract and made an initial payment of $12.5 million for the acquisition of the Michiquillay project in Cajamarca, Peru. The Company has created a multidisciplinary management team to plan the development of this project. As part of this plan, the Company has established contact with the local and regional authorities and communities to promote programs to sustainably developthe area. In 2020, we continued to develop social and environmental programs for the local communities and are concluding a semi-detailed environmental impact assessment. This will allow us to begin a 50,000 meter diamond drilling program in 2021 to verify and update the project´s estimated mineralized materials.

Michiquillay is a world class mining project with estimated mineralized material of 1,150 million tons with an estimated copper grade of 0.63%. When developed, we expect Michiquillay to produce 225,000 tons 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 2028. We believe that Michiquillay will become one of Peru´s largest copper mines. The project will create significant business opportunities in the Cajamarca region, generate new jobs for the local communities and contribute with taxes and royalties to the local, regional and national governments.

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.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our significant accounting policies are discussed in Note 2 “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements, included in Item 8 “Financial Statements and Supplementary Data” of this Annual Report.

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

79

Table of Contents

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 operating lease liabilities, valuation allowances for deferred tax assets and unrecognized tax benefits. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Ore Reserves: For internal ore reserve estimation, we use metal price assumptions of $3.00 per pound for copper and $9.00 per pound for molybdenum. These prices are intended to conservatively approximate average prices over the long term and are based on internal estimates for the curves of long-term metal prices.

However, pursuant to SEC guidance, the reserve information in this report is calculated using average metal prices for the most recent three-year period, except as otherwise stated. We refer to these three-year average metals prices as “current average prices.” Our current average prices for copper are calculated using prices quoted by COMEX, and our current average prices for molybdenum are calculated using prices published in Platt’s Metals Week. Unless otherwise stated, reserve estimates in this report use the following three years average prices for copper and molybdenum as of December 31, 2020:

Certain financial information is based on reserve estimates calculated on the basis of current average prices. These include amortization of intangible assets and mine development. Variations in ore reserve calculations from changes in metal price assumptions generally do not create material changes in our financial results. However, significant decreases in metal prices could adversely affect our earnings by causing, among other things, asset impairment charges, please see “Assets impairment” below. A 20% increase or decrease in three-year average copper prices (current prices) for mineral reserves estimation, which is a reasonable possibility, would not materially affect our statement of earnings as the amount of reserves would not change significantly. Please see Item 2 “Properties—Ore reserves.”

Ore stockpiles on leach pads: The leaching process is an integral part of the mining operations carried out at our open-pit mines. We capitalize the production cost of leachable material at our Toquepala, La Caridad and Buenavista mines recognizing it as inventory. The estimates of recoverable mineral content contained in the leaching dumps are supported by engineering studies. As the production cycle of the leaching process is significantly longer than the conventional process of concentrating, smelting and electrolytic refining, we include current leach inventory (as part of work-in-process inventories) and long-term leach inventory on our balance sheet. Amortization of leachable material is recorded by the units of production method.

On January 1, 2020, the Company aligned its capitalization method for its Peruvian and Mexican operations to capitalize based on the allocation of copper content recoverable between ore and leach material. In addition, inventory consumption is now valued at the average unit cost, instead of the declining percentages of recovery method used previously. As a result of these changes, during 2020 the value of capitalized material decreased by $196.4 million and consumption decreased by $29.3 million when compared to the previous capitalization method.

Management has evaluated ASC 250-10 and considered appropriate guidance to conclude that the aforementioned classifies as a change in accounting estimate, and therefore should affect accounting books prospectively. Management believes that this new method will result in a more accurate valuation of this material.

Asset Retirement Obligation: Our mining and exploration activities are subject to various laws and regulations governing the protection of the environment. Accounting for reclamation and remediation obligations requires management to make estimates unique to each mining operation of the future costs we will incur to complete the reclamation and remediation work required to comply with existing laws and regulations. These estimates are based in part on our inflation and credit rate assumptions. Actual costs incurred in future periods could differ from amounts estimated. Additionally, future changes to environmental laws and regulations could increase the extent of reclamation and remediation work required to be performed by us. Any such increases in future costs could materially impact the

80

Table of Contents

amounts charged to operations for reclamation and remediation. In 2020, the Company made a change in the estimate for the asset retirement obligation for its Mexican operations, mainly due to a detailed review of the closing activities required for each facility. The effect of this change was an increase in the asset retirement obligation of $269.3 million, which was recorded in December 2020.

Asset retirement obligations are further discussed in Note 10 “Asset Retirement Obligation” to the consolidated financial statements included herein.

Revenue Recognition: For certain of our sales of copper and molybdenum products, customer contracts allow for pricing based on a month subsequent to shipping, in most cases within the following three months and in a few cases, in a period that can exceed three months. In such cases, revenue is recorded at a provisional price at the time of shipment. The provisionally priced copper sales are adjusted to reflect forward LME or COMEX copper prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract. In the case of molybdenum sales, for which there are no published forward prices, the provisionally priced sales are adjusted to reflect the market prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract. (See details in “Provisionally Priced Sales” under this Item 7).

Income Taxes: In preparing our consolidated financial statements, we recognize income taxes in each of the jurisdictions in which we operate. For each jurisdiction, we calculate the actual amount currently payable or receivable, as well as deferred tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in rate is recognized through the income tax provision in the period that the change is enacted.

A valuation allowance is provided for those deferred tax assets for which it is more likely than not that the related benefits will not be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income, as well as feasible tax planning strategies in each jurisdiction. If we determine that we will not realize all or a portion of our deferred tax assets, we will increase our valuation allowance with a charge to income tax expense. Conversely, if we determine that we will ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced with a credit to income tax expense.

Our Company’s operations involve dealing with uncertainties and judgments in the application of complex tax regulations in multiple jurisdictions. The final taxes paid are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions and resolution of disputes arising from federal, state, and international tax audits. We recognize potential liabilities and record tax liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes will be due. We follow the guidance of ASC 740 “Income Taxes” to record these liabilities. (See Note 7 “Income Taxes” of the consolidated financial statements for additional information). We adjust these reserves in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. We recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

On December 22, 2017, the Tax Cuts and Jobs Act (“TCJA”) significantly changed U.S. tax law by, among other things, lowering corporate income tax rates from 35% to a flat 21% effective January 1, 2018, implementing a territorial tax system; and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. To address circumstances that could arise because of the late passage of TCJA in 2017, the SEC issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant lacked sufficient information prepared or analyzed

in reasonable detail, to complete accounting under ASC 740 “Accounting For Income Taxes” during the following year (2018).

Asset Impairments: We evaluate our long-term assets when events or changes in economic circumstances indicate that the carrying amount of such assets may not be recoverable. Our evaluations are based on business plans that are prepared using a time horizon that is reflective of our expectations of metal prices over our business cycle. We are currently using an average copper price of $2.20 per pound and an average molybdenum price of $5.00 per pound, which reflect what we believe, for impairment test purposes, is the lower range of the current price environment. The results of our impairment sensitivity analysis, which included a stress test using a copper price assumption of $2.00 per pound and a molybdenum price assumption of $4.00 per pound, showed projected discounted cash flows in excess of the carrying amounts of long-lived assets by margins ranging from 1.3 to 4.3 times such carrying amount.

In recent years, our assumptions for long-term average prices resulted in stricter evaluations for impairment analysis than using the three year average prices for copper and molybdenum prices. Should this situation change in the future with three-year average prices falling below the long-term price assumption, we would assess the need to use the three-year average prices in our evaluations. We use an estimate of the future undiscounted net cash flows of the related asset or asset group over the remaining life to measure whether the assets are recoverable and measure any impairment compared to fair value.

Leases: In 2019, the Company adopted the new leases standard and it resulted in the recognition of right-of-use assets and lease obligations on the Company´s balance sheet. After the analysis of this standard, the Company concluded that all of its existing lease contracts are operating lease contracts. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation by the Company to make lease payments that arise from the lease. Lease right-of-use assets and liabilities are recognized at the inception date based on the present value of lease payments over the lease term. As the Company’s lease contracts do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the inception date to determine the present value of lease payments.

NET SALES

2020-2019: Net sales in 2020 were $7,984.9 million, compared to $7,285.6 million in 2019, which represented an increase of $699.3 million. This 9.6% increase was mainly the result of higher sales volumes of copper (+6.1%), silver (+8.8%), molybdenum (+12.7%) and zinc (+1.0%) as well as higher copper (+2.9%) and silver (+27.7%) prices. This effect was slightly offset by lower molybdenum (−24.0%) and zinc (-11.2%) prices.

2019-2018: Net sales in 2019 were $7,285.6 million, compared to $7,096.7 million in 2018, an increase of $188.9 million. This 2.7% increase was mainly the result of higher copper (+11.3%), molybdenum (+21.7%) and silver (+5.7%) sales volumes, partially offset by copper (−8.1%) and molybdenum (−5.0%) prices.

2020-2019: Non-operating income and expense were a net expense of $374.9 million in 2020 compared to a net expense of $326.5 million in 2019. The $48.4 million increase in net expense in 2019 was mainly due to:

$ 20.5 million increase in the miscellaneous expense, net, principally due to a $24.2 million provision related to rain damages at our Peruvian operations.
$ 20.5 million increase in interest expense, which was attributable to the Minera Mexico debt issuance in September 2019;
$ 5.4 million decrease in capitalized interest, given that completed projects in Peru have been transferred to operations, and
$ 2.0 million of lower interest income.

2019-2018: Non-operating income and expense were a net expense of $326.5 million in 2019 compared to a net expense of $291.8 million in 2018. The $34.7 million increase in net expense in 2019 was mainly due to:

$ 51.6 million of lower capitalized interest, as completed projects in Peru have been transferred to operations.
$ 12.0 million of higher interest expense due to the Minera Mexico debt issuance in September 2019; partially offset by,
$ 23.7 million of lower miscellaneous expense, net, which includes a $25.0 million insurance payment due to rain damages suffered in our Peruvian operations, and
$ 5.2 million of higher interest income.

The increase in the 2020 effective income tax rate from the prior year was primarily attributable to a movement in exchange gains and losses from the devaluation of the Mexican peso and the Peruvian sol against the U.S. dollar; an increase in the Peruvian special mining tax; and an increase in the Mexican and Peruvian royalty. In 2018 the Company, pursuant to SAB 118, completed its analysis of the effects of the 2017 U.S. tax reform and recorded a non-cash tax provision of $30.9 million in addition to the non-cash amount of $785.9 recorded in 2017. After applying the conditions of US tax reform in 2017, the aforementioned led to a total non-cash tax provision for 2017 and 2018 to $816.8 million.

Equity earnings of affiliate

In 2020, 2019 and 2018 we recognized $6.4 million, $10.7 million and $12.3 million in equity earnings, respectively, which were associated with our 44.2% interest in the Tantahuatay mine.

Net Income attributable to the non-controlling interest

Net income attributable to the non-controlling interest in 2020 was $7.4 million, compared to $6.1 million in 2019, and $5.2 million in 2018. This increased in 2020 and 2019 by $1.3 million and $0.9 million respectively. These changes were the result of higher earnings at our Peruvian operations in both years.

Income attributable to SCC

Our net income attributable to SCC in 2020 was $1,570.4 million, compared to $1,485.8 million in 2019 and $1,543.0 million in 2018. The increase in 2020 net income attributable to SCC was mainly due to growth in net sales. Net income attributable to SCC decreased in 2019, which was mainly due to increases in the cost of sales and depreciation, amortization and depletion.

SEGMENT RESULTS ANALYSIS

We have three segments: the Peruvian operations, the Mexican open-pit operations and the Mexican underground mining operations. Please see a detailed definition of these segments in Item 1 “Business—Business Reporting Segments.”

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

2020: Net income was $1,577.8 million, which represented approximately 56.7% of the net operating cash flow. A net increase in operating assets and liabilities increased operating cash flow by $483.7 million, which was attributable to the following variances in operating assets and liabilities:

$(236.0) million increase in trade accounts receivable, which was mainly driven by a significant increase in copper prices during the last quarter of 2020.
$223.6 million of net decrease in inventory, which included a $165.2 million decrease in the leaching inventory mainly at our Peruvian operations, and a $36.4 million decrease in the finished goods inventory, principally at our Mexican operations.
$313.8 million increase in accounts payable and accrued liabilities, which primarily reflected growth in income taxes and workers’ participation accruals at our Peruvian and Mexican operations.
$182.3 million decrease in other operating assets and liabilities, which mainly included a decrease in prepaid taxes and a drop in receivables to related parties.

2019: Net income was $1,491.9 million, which represented approximately 78% of the net cash provided by operating activities. A net decrease in operating assets and liabilities decreased operating cash flow by $347.0 million and included:

$(184.9) million decrease in accounts payable and accrued liabilities, which included principally income taxes and workers’ participation payments as a result of higher earnings at our Mexican and Peruvian operations in 2018.
$(10.5) million increase in trade accounts receivable mainly because of higher sales volumes at our Peruvian operations.

Other Liquidity Considerations

We expect that we will meet our cash requirements for 2021 and beyond from cash on hand and internally generated funds. In addition, we believe that we will be able to access additional external financing on reasonable terms, if required.

As of December 31, 2020, $1,297.3 million of the Company´s total cash, cash equivalents and short-term investments of $2,594.4 million were held by foreign subsidiaries. The cash, cash equivalents and short-term investments maintained in our foreign operations are generally used to cover local operating and investment expenses. Earnings of the Company’s Peruvian branch are not subject to transition taxes since they are taxed in the United States on a current basis.

Share repurchase program: In 2008, our Board of Directors (“BOD”) authorized a $500 million share repurchase program that has since been increased by the BOD and is currently authorized to $3 billion. Since the inception of the program through December 31, 2020, we have purchased 119.5 million shares of our common stock at a cost of $2.9 billion. These shares are available for general corporate purposes. We may purchase additional shares of our 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. For further details please see Item 5 “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities—SCC common stock repurchase plan.”

Dividend: On January 21, 2021, the BOD authorized a dividend of $0.60 per share to be paid on February 24, 2021 to shareholders of record at the close of business on February 10, 2021.

FINANCING

Our total debt at December 31, 2020 was $6,544.2 million, compared to $6,940.8 million at December 31, 2019, net of the unamortized discount and issuance costs of notes issued under par for $107.0 million and $110.4 million as of December 31, 2020 and 2019 respectively. This debt is all denominated in dollars at fixed interest rates, weighed at 5.69%.

The ratio of total debt to total capitalization was 47.4% as of December 31, 2020, compared to 50.2% as of December 31, 2019. In addition, the ratio of net debt to net capitalization was 35.2% as of December 31, 2020, compared to 41.8% as of December 31, 2019.

We define net debt as total debt, including current maturities, minus cash, cash equivalents and short-term investments balance. We believe that net debt is useful to investors as a measure of our financial position. We define net capitalization as the sum of net debt and equity. We use the net debt to net capitalization ratio as measure of our indebtedness position and to determine how much debt we can take in addition to the use of the equity and of the balance sheet in general. We define total capitalization as the sum of the carrying values of our total debt, including current maturities and equity. A reconciliation of our net debt to net capitalization and total debt to total capitalization as included in the consolidated balance sheet is presented under the sub heading “Non-GAAP Information Reconciliation” below.

Please see Note 11 “Financing” for a discussion about the covenants requirements related to our long-term debt.

Capital Investment Program

A discussion of our capital investment program is an important part of understanding our liquidity and capital resources. We expect to meet the cash requirements for these capital investments from cash on hand, internally generated funds and from additional external financing if required. For information regarding our capital expenditure programs, please see the discussion under the caption “Capital Investment Program” under this Item 7.

(a)The above table does not include any scheduled payments related to U.S. uncertain tax position liabilities because there is often a high degree of uncertainty regarding the timing of future cash outflows. As of December 31, 2020, the tax liability recognized by the Company is $66.1 million and is netted against the deferred tax asset in the consolidated Balance Sheet. Please refer to Note 7 “Income Taxes” of the consolidated financial statements.

Long-term debt payments do not include the debt discount valuation account and issuance costs of $107.0 million.

Interest on debt is calculated at rates in effect at December 31, 2020. As all our debt is at fixed rates, future expenditures will not change due to rate changes. Please refer to Note 11 “Financing” of the consolidated financial statements for a description of our long-term debt arrangements and credit facilities.

Workers’ participation is currently calculated based on Peruvian Branch and Mexican pre-tax earnings. In Peru, the provision for workers’ participation is calculated at 8% of pre-tax earnings. The current portion of this participation, which is accrued during the year, is based on the Peruvian Branch’s taxable income and is largely distributed to workers after final results are determined for the year. Amounts in excess of 18 times a worker’s salary are distributed to governmental bodies. In Mexico, workers’ participation is determined using the guidelines established in the Mexican income tax law at a rate of 10% of pre-tax earnings as adjusted by the tax law.

Operating leases include lease payments for power generating facilities to MGE, vehicles and properties. Please refer to Note 9 “Leases” of the consolidated financial statements.

Pension and post retirement obligations include the benefits expected to be paid under our pension and post-retirement benefit plans. Please refer to Note 12 “Benefit Plans” of the consolidated financial statements.

Asset retirement obligations include the aggregate amount of closure and remediation costs for our Peruvian mines and facilities to be paid under the mine closure plans approved by MINEM and the closure and remediation costs of our Mexican operations. See Note 10 “Asset Retirement Obligation.”

In June 2014, we entered into a power purchase agreement for 120 megawatt (“MW”) with the state company Electroperu S.A., which began supplying energy for our Peruvian operations for twenty years starting on April 17, 2017. In July 2014, we entered into a power purchase agreement for 120MW with a private power generator Kallpa Generacion S.A. (“Kallpa”), which began supplying energy for our Peruvian operations for ten years starting on April 17, 2017. In May 2016, we signed an additional power purchase agreement for a maximum of 80MW with Kallpa,

94

Table of Contents

under which Kallpa will supply energy to the operations related to the Toquepala Expansion and to other minor projects for ten years starting on May 1, 2017 and ending after ten years of commercial operation of the Toquepala Expansion or on April 30, 2029; whichever occurs first.

Additionally, we have a commitment to purchase power for our Mexican operations from MGE, a subsidiary of Grupo Mexico through 2032. See Note 13 “Commitment and Contingencies—Other commitments”.

Amounts indicated in the table above are based on our long-term estimated power costs, which are subject to change as energy generation costs change and our forecasted power requirements through the life of the agreements change.

Capital investment projects include committed purchase orders and executed contracts for our Mexican projects and for our Peruvian expansion projects at Tia Maria and the Toquepala mine.

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 implementing controls that are frequently reviewed and tested, including a risk matrix that considers the possible threats through an impact and probability analysis, actions to avoid or mitigate them and the corresponding testing plan. In 2020, we did not have any material cybersecurity breaches in our systems.

CLIMATE CHANGE

Peruvian operations: On April 17, 2018, the Peruvian government enacted Law N. 30754, establishing a Climate Change Framework. Through this law, promoting public and private investments in climate change management is declared to be of national interest. The law proposes to create an institutional framework to address climate change in Peru, outlining new measures, particularly with respect to climate change mitigation. It includes, for example, provisions regarding: increasing 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 climate change framework law in Latin America to incorporate obligations from the Paris Agreement. Regulations to this law were enacted by Supreme Decree 013-2019, which was 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. The Company anticipates initiating a multi-year process to adopt applicable reporting recommendations of the Task-Force on Climate Related Financial Disclosures (TCFD) once new Peruvian climate change regulations applicable to non-governmental entities are implemented. The Company is committed to the environment and to managing climate-related impacts. The Company’s focus is to seek continuous improvement in the responsible use of natural resources while complying with strict applicable legal standards for prevention, mitigation, control and remediation of environmental impacts. Implementing continuous improvement in the Company’s processes improves efficiency in the use and consumption of energy, water, and other natural resources.

Mexican operations: Grupo Mexico, the indirect parent of SCC has issued sustainability reports under the Global Reporting Initiative (GRI) for more than 10 years. Grupo Mexico also participates in different Mexican and international reporting programs such as the Greenhouse Gases (GHG) Mexico Program and CDP (formerly the Carbon Disclosure Project). In 2013, GHG and CDP signed a memorandum of understanding to work on aligning their reporting frameworks. Grupo Mexico’s 2018 CDP questionnaire included responses to the Task Force on Climate-Related Disclosure or TCFD concerns. In compliance with the 2012 Mexican Climate Change Law, Grupo Mexico’s GHG emissions are reported and verified independently. Grupo Mexico’s Sustainability Reports, which disclose inventories of GHG emissions, can be found at “https://www.gmexico.com/en/Pages/development.aspx”. On October 18, 2017, Grupo Mexico was selected to join the S&P Sustainability Indices MILA Pacific Alliance (DJSI MILA). In 2017, this regional

sustainability index included 42 leading companies in sustainability from the countries that form part of the Pacific Alliance: Mexico, Chile, Colombia and Peru.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity price risk:

For additional information on metal price sensitivity, refer to “Metal Prices” in Part II, Item 7 of this annual report.

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 or 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 in each period prior to settlement. See Note 18 to the consolidated financial statements for further information about these provisional sales.

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. Given that 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 an exchange rate variance of the sol or the peso, resulting in a re-measurement gain or loss in our financial statements. Recent inflation and exchange rate variances for the three years ended December 31, 2020 are provided in the table below:

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTAL DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Southern Copper Corporation and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of earnings, comprehensive income, changes in stockholders´ equity, and cash flows for each of the three years in the period ended December 31, 2020 and the related notes and schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2020 based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2021 expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Emphasis of a Matter

We draw attention to Note 1 of the financial statements, which describes the effects of the outbreak of coronavirus disease ("COVID-19") as of December 31, 2020 and for year then ended.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Ore stockpiles on Leach Pads – Refer to Note 4 to the financial statements

Critical Audit Matter Description

The Company has recorded Ore stockpiles on leach pads of $1,423.5 million as of December 31, 2020 ($298.5 million presented as current and $1,125.0 million presented as non-current assets), for the capitalization of inventory costs related to leachable material.

The Company used the recoverable copper content grade when determining the capitalization of inventory costs related to leachable material. The leachable material inventory determined could be misstated if the monthly average recoverable copper content grade and the solubility index used by the Company does not correspond to the actual results obtained from the laboratories.

We identified the copper content grade and solubility index as a critical audit matter because of the significant judgments made by management to support its assertion that these capitalized costs are probable of recovery. Addressing this matter required a high degree of auditor judgment in evaluating whether the audit evidence obtained supports management’s assertion that these costs are probable of future recovery.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s assertions that extraction and movement of material costs are capitalized in the appropriate amounts included the following, among others:

We tested the effectiveness of controls over management’s review of the copper content grade used to determine the monthly average rate to be used in the calculation, which included an evaluation of the competence, objectivity and authority of the personnel involved in the determination of the copper content grade and the solubility index; the identification of costs to be capitalized as part of the leaching process; and reconciliations of mineral received for the leaching process.
We tested the effectiveness of controls that ensure that the net realizable value was higher than the unit cost for the leachable material capitalized to conclude that no impartment existed. We performed control testing to ensure that the net realizable value was higher than the unit cost for the leachable material capitalized to conclude that no impartment existed.
We tested the effectiveness of general IT controls for the relevant systems identified that process information that are considered significant inputs in the calculation of the Company’s estimate.
We developed an independent expectation of the amounts of leachable material that should have been capitalized and amortized to compare it to the recorded balances.
We independently recalculated the monthly average copper content grade and the monthly average solubility index to obtain the reasonability of the inputs used in the estimate.
We performed a recalculation of the net realizable value and the total tons to determine that the unit cost was lower than the net realizable value. To determine the net realizable value we considered the annual average price, premium and sales expenses.
We involved technical specialists to evaluate the methodology used by the Company to determine the recoverability of copper from the leach pads and challenge, from a technical perspective, if the balance as of December 31, 2020 represents copper that will be recovered as estimated by the Company.

Uncertain Tax Positions (Deferred income tax) – Refer to Note 7 to the financial statements

Critical Audit Matter Description

In accordance with ASC 740 - Income Taxes, the Company must perform an analysis to determine that Uncertain Tax Positions (UTPs) are identified, evaluated, valued, recorded and disclosed in the Company’s consolidated financial statements in the correct period and amounts. The Company’s UTPs as of December 31, 2020, were $66.1 million.

101

Table of Contents

We identified the UTPs as a critical audit matter because of the multiple jurisdictions in which the Company files its tax returns and the complexity of the tax laws and regulations. This identification process includes resolution of any related appeals or litigation processes that are based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company must presume that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. As the Company operates in three different jurisdictions, this requires a high degree of auditor judgment and an increased extent of effort, including the need to involve our income tax specialists, when performing audit procedures to evaluate the reasonableness of how management determines whether it is more likely than not that a tax position will be sustained upon examination.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to UTPs included the following, among others:

We tested the effectiveness of internal controls that address management processes to identify, evaluate, value, record and disclose significant UTPs.
With the assistance of our income tax specialists, we read and evaluated management’s documentation obtained an understanding of potential UTPs including, the annual tax returns filed, calculations prepared by management, reconciliation of footnote disclosures.
We made inquiries of management, including the Company’s tax department and internal legal counsel, regarding the identification and status of UTPs.
We obtained confirmation letters from the Company’s external lawyers to evaluate whether any tax contingencies existed and determine completeness of the UTPs identified.
We substantively tested UTPs on a sample basis obtaining evidence to evaluate whether the likelihood of occurrence criteria (more likely than not) has been applied appropriately and tax positions were measured at maximum amounts by applying the likelihood of occurrence criterion.
We evaluated whether the estimates of UTPs were consistent with evidence obtained in other areas of the audit.

Estimate of Tia Maria Project Impairment Indicators (Property and mine development, net) – Refer to Notes 5 and 13 to the financial statements

Critical Audit Matter Description

The Tia Maria mining project in Peru has already received the construction license approval from the Peruvian Mining Council on October 30, 2019. The Company's commitment is to begin the development of the project within the framework of a favorable social atmosphere, working with the local population. This project budget is approximately $1.4 billion and has an investment as of December 31, 2020 of approximately $338.8 million that includes investment in property, plant and equipment of $220.1 million and $118.7 million representing intangible assets primarily composed of engineering studies and the Environmental Impact Study (EIS). The Company evaluates long-term assets when events or changes in economic circumstances indicate that the carrying amount of such assets may not be recoverable. The Company’s evaluations are based on business plans that are prepared using a time horizon that is reflective of their expectations of metal prices, costs and other economic variables over its business cycle.

We considered that the engineering studies and the EIS and other permits and studies composing the intangible assets balance could be impaired if the business plans of the Company changes or other external factors occur once the construction begins.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to identification of events or changes in circumstances that may indicate the carrying amount of the intangibles related to the Tia Maria Project may not be recoverable included the following, among others:

We tested the effectiveness of controls over management’s identification of possible circumstances that may indicate that the carrying amounts are no longer recoverable.
We obtained support documentation to ensure that the main inputs used in the business model were reasonable.

102

Table of Contents

We read publicly available information regarding projections of copper prices.
We obtained support documentation to test the stress testing performed by management over the business model, considering changes in main variables impacting the model such as copper price and cost changes (increases/decreases), among others and appropriate evidence to conclude that no impairment indicators existed as of December 31, 2020.

SOUTHERN COPPER CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—DESCRIPTION OF THE BUSINESS:

The Company is a majority-owned, indirect subsidiary of Grupo Mexico S.A.B. de C.V. (“Grupo Mexico”). At December 31, 2020, Grupo Mexico through its wholly-owned subsidiary Americas Mining Corporation (“AMC”) owned 88.9% of the Company’s capital stock. The consolidated financial statements presented herein consist of the accounts of Southern Copper Corporation ("SCC", "Southern Copper" or the “Company”), a Delaware corporation, and its subsidiaries. The Company is an integrated producer of copper and other minerals, and operates mining, smelting and refining facilities in Peru and Mexico. The Company conducts its primary operations in Peru through a registered branch (the "Peruvian Branch" or “Branch” or “SPCC Peru Branch”). The Peruvian Branch is not a corporation separate from the Company. The Company's Mexican operations are conducted through subsidiaries. The Company also conducts exploration activities in Argentina, Chile, Ecuador, Mexico and Peru.

COVID – 19 PANDEMIC

Since the World Health Organization (“WHO”) declared the COVID-19 virus outbreak as a global pandemic, all the countries where the Company operates and conducts exploration activities, as well as the countries where its main customers and suppliers are located, have published health and safety rules and restrictions on individuals and business activities.

As of December 31, 2020, the Company‘s production facilities in Mexico and Peru were working at approximately 98% of their production capacity. The Company has developed a rigorous COVID-19 emergency protocol.

The Company has restarted exploration activities at all of its locations, except in Chile due to local restrictions. The Company restarted exploration activities in Ecuador and Argentina in September 2020 and at the end of the second quarter of 2020, respectively.

The financial reporting process and the information required to prepare the Company’s financial statements suffered no interruption and the financial statements were prepared without restrictions or difficulties.

SCC´s Corporate Crisis Committee as well as its Crisis Committees in Mexico and Peru continue to closely monitor the impact of the pandemic and to analyze and quickly resolve any issues that may arise. As of December 31, 2020, there were no major delays in the supply of materials and services critical for the operations and sales. Also, shipments and collections have registered no known major delays.

After completing the first stage of its capital programs at Buenavista in Mexico and Toquepala in Peru, the Company currently does not have major capital expenditures commitments (see Note 13 - Commitments and Contingencies). The Company paid the first tranche of its 2010 bonds of $400 million on April 15, 2020. The Company has no other major debt maturity until 2022.

The Company performed a qualitative analysis and as of December 31, 2020 identified no indicators of impairment. As the Company reported, the results of its impairment sensitivity analysis showed projected discounted cash flows in excess of the carrying amounts of long-lived assets by margins ranging from 1.3 to 4.3 times such carrying amount. This analysis included a stress test using a copper price assumption of $2.00 per pound and a molybdenum price assumption of $4.00 per pound.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of consolidation—

The consolidated financial statements include the accounts of subsidiaries of which the Company has voting control, in accordance with Accounting Standards Codification (“ASC”) 810 Consolidation. Such financial statements are prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP").

Use of estimates—

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the carrying value of ore reserves that are the basis for future cash flow estimates and amortization calculations; environmental reclamation, closure and retirement obligations; estimates of recoverable copper in mill and leach stockpiles; asset impairments (including estimates of future cash flows); unrecognized tax benefits; valuation allowances for deferred tax assets; and fair value of financial instruments. Management bases its estimates on the Company's historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.

Revenue recognition—

The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company's revenues are measured based on consideration specified in the contract with each customer. Disclosures regarding disaggregation of revenues and contract balances are disclosed within Note 18 "Segment and related information".

The Company’s marketing strategy and annual sales planning emphasize developing and maintaining long-term customer relationships. Generally, 80% to 90% of the Company’s metal production is sold under annual or longer-term contracts, which specify a volume of mineral to be sold over a stated period and delivery schedule; the price at which mineral will be sold at each delivery date is generally determined by the weekly or monthly average rate of the commodity published by major metal exchanges at specific dates stipulated within each contract. The Company considers each contract to be a single performance obligation, represented by the delivery of a series of distinct goods that are substantially the same, with the same pattern of transfer to the Company’s customers. The Company concluded this as, based on the nature of its contracts, customers receive the benefit of mineral sold as it is shipped per the terms of the contracts at each contractual delivery date. Likewise, each shipment of product represents the same measure of progress as other shipments within the contract. Accordingly, the Company recognizes revenues for each contract over the period of time in which the specified quantity of mineral is delivered. In doing so, the Company considers that it has a right to consideration from its customers in an amount that corresponds directly to the value transferred to those customers that being the quantity of mineral delivered at the price per unit delivered. Accordingly, the Company recognizes revenue at the amount to which it has the right to invoice (the invoice practical expedient), as it believes that this method is a faithful depiction of the transfer of goods to its customers.

For contracts with a term greater than one year, the Company is unable to disclose an allocation of the transaction price to the remaining unsatisfied performance obligation, given that unit prices of mineral sold are determined by published commodity prices at specified dates within the contract. The volume of mineral to be delivered after the first year of the contract is subject to annual volume negotiations in accordance with the terms of the contract. As of December 31, 2020, the Company has long-term contracts with promises to deliver in 2021 for a total of 208,000 metric tons of copper concentrate, 48,000 metric tons of copper cathodes, 43,329 tons of molybdenum concentrate and 325,700 tons of sulfuric

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

acid. This is an estimate that will vary in 2022 and 2023 based on the negotiations with the customers as mentioned above.

The remainder of the Company’s revenues, including its by-product revenues, are generated by spot sales that are recognized at a point in time.

Under both sales models, revenue is recognized when or as the performance obligations are satisfied, when the Company transfers control of the goods and title passes to the customer. Considering the International Commercial Terms (Incoterms) utilized by the Company, control is transferred generally upon the completion of loading the material at the point of origin. This is the point at which the customer obtains legal title to the product as well as the ability to direct the use of and obtain substantially all of the remaining benefits of ownership of the asset. Additionally, payment is generally due upon the delivery of the shipping and title documents at the point of origin, customers typically have 30 days to remit payment. Copper and non-copper revenues are measured based on the monthly average of prevailing commodity prices according to the terms of the contracts. The Company provides allowances for doubtful accounts based upon historical bad debt and claims experience and periodic evaluation of specific customer accounts.

Substantially all of the Company’s sales are made under carriage and insurance paid to, or cost, insurance and freight Incoterms, whereby the Company is responsible for providing shipping and insurance after control of the inventory has been transferred to the customer. According to the terms of the Company’s contracts, these services are not distinct within the context of the contract, and they are not separately identifiable from the other promises within the contract. Additionally, it is the Company policy and it has a long-standing history of providing shipping and insurance services to its customers. Accordingly, shipping and insurance are not considered separate performance obligations. The related costs of shipping and insurance are presented within the cost of sales line in the accompanying consolidated statements of income.

Furthermore, the Company considered the impact of the shipping and insurance services on the determination of when control is transferred to its customers. It has concluded that the terms of these services do not impact its customers’ ability to sell, pledge, or otherwise use the products in shipment. Also, there is a small likelihood and minimal history of lost or damaged goods during shipment. Considering these factors, combined with the other indicators of control previously mentioned, the Company has concluded that these services do not impact the determination that control is transferred at the point of origin.

For certain of the Company’s sales of copper and molybdenum products, customer contracts allow for pricing based on a month subsequent to shipping, in most cases within the following three months and occasionally in some cases a few additional months. In such cases, revenue is recorded at a provisional price at the time of shipment. The provisionally priced copper sales are adjusted to reflect forward LME or COMEX copper prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract. In the case of molybdenum sales, for which there are no published forward prices, the provisionally priced sales are adjusted to reflect the market prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract.

These provisional pricing arrangements are accounted for separately from the contract as an embedded derivative instrument under ASC 815-30 “Derivatives and Hedging—Cash Flow Hedges.” The Company sells copper in concentrate, anode, blister and refined form at industry standard commercial terms. Net sales include the invoiced value of copper, zinc, silver, molybdenum, sulfuric acid and other metals and the corresponding fair value adjustment of the related forward contract of copper and molybdenum. Disclosure regarding adjustments to sales for provisionally priced contracts is disclosed within Note 18 “Segment and related information”.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Cash and cash equivalents—

Cash and cash equivalents include bank deposits, certificates of deposit and short-term investment funds with original maturities of three months or less at the date of purchase. The carrying value of cash and cash equivalents approximates fair value.

Short-term investments—

The Company accounts for short-term investments in accordance with ASC 320-10 “Investments Debt and Equity Securities-Recognition.” The Company determines the appropriate classification of all short-term investments as held-to-maturity, available-for-sale or trading at the time of purchase and re-evaluates such classifications as of each balance sheet date. Unrealized gains and losses on available-for-sale investments, net of taxes, are reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity, unless such loss is deemed to be other than temporary.

Inventories—

The Company principally produces copper and, in the production process, obtains several by-products, including molybdenum, silver, zinc, sulfuric acid and other metals.

Metal inventories, consisting of work-in-process and finished goods, are carried at the lower of average cost or net realizable value (NRV). Costs of work-in-process inventories and finished goods mainly include power, labor, fuel, operating and repair materials, depreciation, amortization, depletion, and other necessary costs related to the extraction and processing of ore, including mining, milling, concentrating, smelting, refining, leaching and chemical processing. Costs incurred in the production of metal inventories exclude general and administrative costs. Once molybdenum, silver, zinc and other by-products are identified, they are transferred to their respective production facilities and the incremental cost required to complete production is assigned to their inventory value.

Work-in-process inventories represent materials that are in the process of being converted into a saleable product. Conversion processes vary depending on the nature of the copper ore and the specific mining operation. For sulfide ores, processing includes milling and concentrating and results in the production of copper and molybdenum concentrates.

Finished goods include saleable products (e.g., copper concentrates, copper anodes, copper cathodes, copper rod, molybdenum concentrate and other metallurgical products).

Supplies inventories are carried at the lower of average cost or net realizable value (NRV).

Long-term inventory-Ore stockpiles on leach pads.

The leaching process is an integral part of the mining operations carried out at the Company’s open-pit mines. The Company capitalizes the production cost of leachable material at its Toquepala, La Caridad and Buenavista mines, recognizing it as inventory. This cost includes mining and haulage costs incurred to deliver ore to leach pads, depreciation, amortization, depletion and site overhead costs. The estimates of recoverable mineral content contained in the leaching dumps are supported by engineering studies. As the production cycle of the leaching process is significantly longer than the conventional process of concentrating, smelting and electrolytic refining, the Company includes current leach inventory (included in work-in-process inventories) and long-term leach inventory on its balance sheet. On January 1, 2020, the Company aligned its capitalization method for its Peruvian and Mexican operations to capitalize based on the allocation of copper content recoverable between ore and leach material. In addition, inventory consumption is now valued at the average unit cost, instead of the declining percentages of recovery method used previously. As a result of

112

Table of Contents

SOUTHERN COPPER CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

these changes, during 2020 the value of capitalized material decreased by $196.4 million and consumption decreased by $29.3 million when compared to the previous capitalization method.

Management has evaluated ASC 250-10 and considered appropriate guidance to conclude that the aforementioned classifies as a change in accounting estimate, and therefore should affect accounting books prospectively. Management believes that this new method will result in a more accurate valuation of this material.

Property—

Property is recorded at acquisition cost, net of accumulated depreciation and amortization. Cost includes major expenditures for improvements and replacements, which extend useful lives or increase capacity and interest costs associated with significant capital additions. Maintenance, repairs, normal development costs at existing mines and gains or losses on assets retired or sold are reflected in earnings as incurred.

Buildings and equipment are depreciated on the straight-line method over estimated lives from two to 50 years or the estimated life of the mine if shorter.

Mine development

Mine development includes primarily the cost of acquiring land rights to an exploitable ore body, pre-production stripping costs at new mines that are commercially exploitable, costs associated with bringing new mineral properties into production, and removal of overburden to prepare unique and identifiable areas outside the current mining area for such future production. Mine development costs are amortized on a unit of production basis over the remaining life of the mines.

Diverse practices exist in the mining industry relative to the treatment of drilling and other related costs to delineate new ore reserves. The Company follows the practices outlined in the next two paragraphs in its treatment of drilling and related costs.

Drilling and other associated costs incurred in the Company's efforts to delineate new resources, whether near-mine or Greenfield are expensed as incurred. These costs are classified as mineral exploration costs. Once the Company determines through feasibility studies that proven and probable reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs. These mine development costs incurred prospectively to develop the property are capitalized as incurred, until the commencement of production, and are amortized using the units of production method over estimated life of the ore body. During the production stage, drilling and other related costs incurred to maintain production are included in production cost in the period in which they are incurred.

Drilling and other related costs incurred in the Company’s efforts to delineate a major expansion of reserves at an existing production property are expensed as incurred. Once the Company determines through feasibility studies that proven and probable incremental reserves exist and that the drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs. These incremental mine development costs are capitalized as incurred, until the commencement of production and amortized using the units of production method over the estimated life of the ore body. A major expansion of reserves is one that increases total reserves at a property by approximately 10% or more.

For the years ended December 31, 2020, 2019 and 2018, the Company did not capitalize any drilling and related costs.

113

Table of Contents

SOUTHERN COPPER CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Asset retirement obligations (reclamation and remediation costs)—

The fair value of a liability for asset retirement obligations is recognized in the period in which the liability is incurred. The liability is measured at fair value and is adjusted to its present value in subsequent periods as accretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying value of the related long-lived assets and depreciated over the asset's useful life.

Intangible assets—

Intangible assets include primarily the excess amount paid over the book value for investment shares, which are presented as mining concessions, and mining and engineering development studies. Intangible assets are carried at acquisition costs, net of accumulated amortization and are amortized principally on a unit of production basis over the estimated remaining life of the mines. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.

Debt issuance costs—

Debt issuance costs related to a recognized debt liability are presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the treatment of a debt discount.

Ore reserves—

The Company periodically reevaluates estimates of its ore reserves, which represent the Company’s estimate as to the amount of unmined copper remaining in its existing mine locations that can be produced and sold at a profit. Such estimates are based on engineering evaluations derived from samples of drill holes and other openings, combined with assumptions about copper market prices and production costs at each of the respective mines.

The Company updates its estimate of ore reserves at the beginning of each year. In this calculation, the Company uses current metal prices which are defined as the average metal price over the preceding three years. The current price per pound of copper, as defined, was $2.816, $2.818 and $2.642 at the end of 2020, 2019 and 2018, respectively. The ore reserve estimates are used to determine the amortization of mine development and intangible assets.

Once the Company determines through feasibility studies that proven and probable reserves exist and that drilling and other associated costs embody a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflow, then the costs are classified as mine development costs and the Company discloses the related ore reserves.

Exploration—

Tangible and intangible costs incurred in the search for mineral properties are charged against earnings when incurred.

Income taxes—

Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the amount of taxable income and pretax financial income and between the tax bases of assets and liabilities and their reported amounts in the financial statements. Deferred tax assets and liabilities are included in the financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized and settled as prescribed in ASC 740 “Income taxes.” As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.

114

Table of Contents

SOUTHERN COPPER CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Deferred income tax assets are reduced by any benefits that, in the opinion of management, are more likely not to be realized.

The Company’s operations involve dealing with uncertainties and judgments in the application of complex tax regulations in multiple jurisdictions. The final taxes paid are dependent upon many factors, including negotiations with tax authorities in various jurisdictions and resolution of disputes arising from federal, state, and international tax audits. The Company recognizes potential liabilities and records tax liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on its estimate of whether, and the extent to which, additional taxes will be due. The Company follows the guidance of ASC 740 “Income taxes” to record these liabilities. (See Note 7 “Income taxes” of the consolidated financial statements for additional information). The Company adjusts these reserves in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the Company’s current estimate of the tax liabilities. If its estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary.

The Company classifies income tax-related interest and penalties as income taxes in the financial statements, as well as interest and penalties, if any, related to unrecognized tax benefits.

Foreign exchange—

The Company’s functional currency is the U.S. dollar. As required by local law, both the Peruvian Branch and Minera Mexico maintain their books of accounts in Peruvian soles and Mexican pesos, respectively.

Foreign currency assets and liabilities are remeasured into U.S. dollars at current exchange rates, except for non-monetary items such as inventory, property, intangible assets and other assets which are remeasured at historical exchange rates. Revenues and expenses are generally translated at actual exchange rates in effect during the period, except for those items related to balance sheet amounts that are remeasured at historical exchange rates. Gains and losses from foreign currency remeasurement are included in earnings of the period.

Gains and (losses) resulting from foreign currency transactions are included in "Cost of sales (exclusive of depreciation, amortization and depletion)."

Asset impairments -

The Company evaluates long-term assets when events or changes in economic circumstances indicate that the carrying amount of such assets may not be recoverable. These evaluations are based on business plans that are prepared using a time horizon that is reflective of the Company’s expectations of metal prices over its business cycle. The Company is currently using a long-term average copper price and an average molybdenum price for impairment tests, reflective of what the Company believes is the lower level of the current price environment. The results of its impairment tests using these long-term copper and molybdenum prices show 0 impairment in the carrying value of their assets.

In recent years testing using assumptions for long-term average prices have resulted in stricter evaluation for impairment analysis than would the higher three year average prices for copper and molybdenum prices. Should this situation reverse in the future with three-year average prices below the long-term price assumption, the Company would assess the need to use the three-year average prices in its evaluations. The Company uses an estimate of the future undiscounted net cash flows of the related asset or asset group over the remaining life to measure whether the assets are recoverable and measures any impairment by reference to fair value.

Other comprehensive income—

Comprehensive income represents changes in equity during a period, except those resulting from investments by owners and distributions to owners. During the fiscal years ended December 31, 2020, 2019 and 2018, the components of "other comprehensive income (loss)" were, the unrecognized gain (loss) on employee benefit obligations and foreign currency translation adjustments.

Business segments-

Company management views Southern Copper as having 3 reportable segments and manages it on the basis of these segments. The segments identified by the Company are: 1) the Peruvian operations, which include the 2 open-pit copper mines in Peru and the plants and services supporting such mines, 2) the Mexican open-pit copper mines, which include La Caridad and Buenavista mine complexes and their supporting facilities and 3) the Mexican underground mining operations, which include 5 underground mines that produce zinc, lead, copper, silver and gold, a coal mine and a zinc refinery. Please see Note 18 “Segments and Related Information.”

The Chief Operating Decision Maker of the Company focuses on operating income as measure of performance to evaluate different segments, and to make decisions to allocate resources to the reported segments. This is a common measure in the mining industry.

Leases -

The Company adopted FASB ASC 842, Leases, effective January 1, 2019. The Company determined if a contract is or contained a lease at its inception. The Company evaluated if a contract gave the right to obtain substantially all of the economic benefits from use of an identified asset and the right to direct the use of the asset, in order to determine if a contract contained a lease. All of the Company’s existing lease contracts are operating lease contracts. For these leases, the Company recognized right-of-use assets and the corresponding operating lease liabilities on its consolidated balance sheet. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation by the Company to make lease payments which arise from the lease. Lease right-of-use assets and liabilities are recognized at the inception date based on the present value of lease payments over the lease term. As the Company’s lease contracts do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the inception date in order to determine the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term, in the cost of sales and operating expenses. The Company elected the transition approach whereby it applied the new leases standard at the adoption date and recognized a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company elected the short-term lease recognition exemption (short-term lease practical expedient) by class of underlying asset (which results in off-balance-sheet accounting for the lease).

ADOPTION OF CREDIT LOSSES STANDARD

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13: “Financial Instruments – Credit Losses (Topic 326)”. This ASU was adopted on January 1, 2020. Prior to adopting this ASU, the Company applied an impairment methodology for accounts receivable arising from revenue transactions within the scope of ASC 606 that is consistent with the provision matrix model contemplated in the new standard. In addition, the new disclosure requirements do not apply to such trade receivables because the collection periods in all cases are less than one year. The Company’s accounts receivable from related parties under common control are excluded from the scope of this ASU. Accordingly, the adoption of this ASU did not have a material impact on the Company’s financial statements or related disclosures.

Goodwill includes $17.0 million generated in 1997 as a result of purchasing a third party interest in the Buenavista mine. It also includes $24.9 million representing the amount of the purchase price in excess of the fair value of the net assets acquired from El Pilar mine. This goodwill is attributable to future benefits that the Company expects to realize from the mine and will not be deductible for income tax purposes.

NOTE 7—INCOME TAXES:

Since March 2009, Grupo Mexico, through its wholly-owned subsidiary AMC, owns an interest in excess of 80% of SCC. Accordingly, SCC’s results are included in the consolidated results of the Grupo Mexico subsidiary for U.S. federal income tax reporting. SCC provides current and deferred income taxes, as if it were filing a separate U.S. federal income tax return.

The introduction of the Global Intangible Low Tax Income or GILTI for tax years beginning in 2018 impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. For 2018-2020, there was no U.S. tax liability from the GILTI inclusion. The Company does not anticipate a tax on GILTI in the future because of increased fixed asset amounts and given the Mexican tax rate of 30%, no U.S. deferred taxes would be recorded. Accordingly, the Company has elected that if GILTI were to apply in the future, a current period expense would be recorded when incurred.

Also introduced with 2017 U.S tax reform and applicable to years 2018 and after is the Base Erosion Anti-Abuse Tax (BEAT). BEAT is a 5% minimum tax for tax year 2018, 10% for the years 2019 through 2025 and 12.5% in years thereafter. It is calculated on a base equal to the Company’s income determined without the tax benefit arising from base erosion payments. The Company did not incur a BEAT liability in 2018, 2019 and 2020 since it has met the safe harbor rule that provides a Company not to be subject to the BEAT if related party payments from the U.S. to foreign entities does not exceed 3% of expenses excluding cost of goods sold. The Company must continue to analyze applicability of the BEAT provisions on a yearly basis.

For all of the years presented, both the Peruvian branch and Minera Mexico filed separate tax returns in their respective tax jurisdictions. Although the tax rules and regulations imposed in the separate tax jurisdictions may vary significantly, similar permanent items exist, such as items which are nondeductible or nontaxable.

The valuation allowance increased by $246.2 million over 2019’s level, which was primarily due to the valuation of unutilized Foreign Tax Credits generated in 2020 and the valuation of Foreign Tax Credits carried forward from prior years. The Peru branch operations are taxed in the U.S. as a flow through entity to SCC. Prior to 2017 U.S. Tax Reform, the U.S. corporate income tax rate was 35% on the Peru earnings, which enabled the company to use more currently generated foreign tax credits. Since tax reform reduced the U.S. tax rate to 21%, there is less U.S. income tax to absorb currently generated FTC’s or carryforwards. Additionally, allowable expenses in the U.S. for percentage depletion and U.S. sourced interest expense on debt reduced the branch income subject to U.S. tax, further limiting utilization of foreign tax credits.

U.S. Tax Matters—

As of December 31, 2020, the Company considers its ownership of the stock of Minera Mexico to be essentially permanent in duration.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

As of December 31, 2020, $1,297.3 million of the Company´s total cash, cash equivalents and short-term investments of $2,594.4 million were held by foreign subsidiaries. The cash, cash equivalents and short-term investments maintained in our foreign operations are generally used to cover local operating and investment expenses. The Company has determined that as of December 31, 2020, a deferred tax asset of $0.2 billion exists with respect to its investment in foreign subsidiaries. Tax accounting guidance provided in ASC 740 requires this asset to be recognized only if the basis difference will reverse in the foreseeable future. Management has no plans that would result in the reversal of this temporary difference and consequently no deferred tax asset has been recorded. Future dividends from these subsidiaries are no longer subject to federal income tax in the U.S., and the Company incurs 0 state income tax liability. Additionally, there are 0 withholding taxes due to the tax treaty between the United States and Mexico. Earnings from the Company’s Peruvian branch are not subject to transition taxes given that they are taxed in the United States on a current basis.

At December 31, 2020, there were $1,040.0 million of foreign tax credits available for carryback or carryforward. These credits have a one-year carryback and a ten-year carryforward period and can only be used to reduce U.S. income tax on foreign earnings. There were 0 other unused U.S. tax credits at December 31, 2020. These credits will expire if not utilized by the end of the years listed below:

These foreign tax credits are presented above on a gross basis and have not been reduced here for any unrecognized tax benefits. These foreign tax credits have been adjusted to include the 2016 Net Operating Loss carryback in the U.S. jurisdiction, increasing foreign tax credits by approximately $15.9 million. In accordance with ASC 740 the Company has recorded $66.1 million for an unrecognized tax benefit as an offset to the Company’s deferred tax asset for foreign tax credits. The remaining foreign tax credits of $973.9 million are being re-valued to zero at December 31, 2020. It is the opinion of management that with the reduction in the U.S. corporate tax rate to 21% and considering the corporate tax rates in Mexico of 30% and in Peru at 29.5%, it is unlikely the excess foreign tax credits can be utilized. Additionally, foreign dividends will no longer be taxed in the U.S., thereby reducing the U.S. tax on the foreign source income that the credits can be used to offset.

Peruvian Tax Matters—

Royalty mining charge: The royalty charge is based on operating income margins with graduated rates ranging from 1% to 12% of operating profits, with a minimum royalty charge assessed at 1% of net sales. The minimum royalty charge is recorded as cost of sales and those amounts assessed at higher rates are included in the income tax provision. The Company has accrued $60.6 million, $42.3 million and $32.9 million of royalty charges in 2020, 2019 and 2018, respectively, of which $31.4 million, $14.2 million and $9.0 million were included in income taxes in 2020, 2019 and 2018, respectively.

Peruvian special mining tax: This tax is based on operating income with graduated rates increasing from 2% to 8.4%. The Company recognized $50.0 million, $38.1 million and $30.6 million in 2020, 2019 and 2018, respectively, with respect to this tax. These amounts are included as “income taxes” in the consolidated statement of earnings.

Mexican Tax Matters—

In 2013, the Mexican Congress enacted tax law changes that became effective on January 1, 2014. Among other effects, the amounts that Minera Mexico recorded during 2019 and paid in 2020 were:

Mining royalty at the rate of 7.5% on taxable earnings before taxes: $60.1 million.
Additional royalty of 0.5% over gross income from sales of gold, silver and platinum: $0.9 million.

On December 09, 2019, the Federal Revenue Law for fiscal year 2020, was published in the Federal Official Gazette, effective as of January 1, 2020. The main tax matters are reported as follows:

Income tax changes - Interest expense limitation based on profit levels: The Reform would subject taxpayers with interest expenses over 20 million Mexican pesos to a net interest expense deduction limitation equal to 30% of “adjusted taxable income.” Nondeductible interest expense for each year could be carried forward for 10 years. “Adjusted taxable income” is defined as taxable income for the year, with an addback for interest deductions on debt, as well as deductions for fixed assets, deferred charges and expenses, and pre-operating expenses. The interest limitation is calculated based on net interest, which is determined as interest income less interest expense. If interest income is greater, there is no limitation. Interest paid to Mexican residents, as well as non-residents, is subject to the limitation, as is interest to related and unrelated parties.

Accounting for Uncertainty in Income Taxes—

The Company has 0 unrecognized Mexican tax benefits.

The Company’s U.S. IRS audit of 2014 -2016 commenced in 2019 and is expected to settle in the first half of 2021.

As of December 31, 2020, the Company’s liability for uncertain tax positions did 0t include accrued interest and penalties in the U.S. jurisdiction. As of December 31, 2019 and December 31, 2018 the Company’s liability for uncertain tax positions included Peruvian accrued interest and penalties of $10.5 and $1.9 million, respectively.

NOTE 8—WORKERS’ PARTICIPATION:

The Company's operations in Peru and Mexico are subject to statutory workers' participation.

In Peru, the provision for workers' participation is calculated at 8% of pre-tax earnings. The current portion of this participation, which is accrued during the year, is based on the Peruvian Branch's taxable income and is distributed to workers following determination of final results for the year. The annual amount payable to an individual worker is capped at the worker’s salary for an 18 month period. Amounts determined in excess of the 18 months of worker’s salary is no longer made as a payment to the worker and is levied first for the benefit of the “Fondo Nacional de Capacitacion Laboral y de Promocion del Empleo” (National Workers’ Training and Employment Promotion Fund) until this entity receives from all employers in its region an amount equivalent to 2,200 Peruvian taxable units (approximately $2.6 million in 2020). Any remaining excess is levied as payment for the benefit of the regional governments. These levies fund worker training, employment promotion, entrepreneurship and various other programs.

In Mexico, workers' participation is determined using the guidelines established in the Mexican income tax law at a rate of 10% of pre-tax earnings as adjusted by the tax law.

The provision for workers’ participation is allocated to “Cost of sales (exclusive of depreciation, amortization and depletion)” and to “selling, general and administrative” in the consolidated statement of earnings, proportional to the number of workers in the production and administrative areas, respectively. Workers’ participation expense for the three years ended December 31, 2020 was as follows (in millions):

NOTE 9—LEASES:

The Company has operating leases for power generating facilities, vehicles and properties. The Company recognizes lease expense 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 two years to 13 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 do not have any material residual value guarantees or material restrictive covenants. As none of the Company’s leases provides 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.

NOTE 10—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 the 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 security for this obligation. Through January 2021, the Company provided total guarantees of $56.5 million.

The closure cost recognized for this liability includes the cost, as outlined in its closure plans, of dismantling the Toquepala and Cuajone concentrators, the Ilo smelter and refinery, and the shops and auxiliary facilities at the 3 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. As result of 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. The Company, however, has not recorded a

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

retirement obligation for the project because the work on the project is 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 an obligation presently exists based on historical government requirements for the closure of any facility. The overall cost recognized for mining closure in Mexico includes the estimated costs of dismantling concentrators, smelter and refinery plants, shops and other facilities.

During 2020, the Company made a change in the estimate for the asset retirement obligation for its Mexican operations, mainly due to a detailed review of the closing activities required for each facility. The effect of this change was an increase in the asset retirement obligation of $269.3 million, which was recorded in December 2020.

The following table summarizes the asset retirement obligation activity for the years ended December 31, 2020 and 2019 (in millions):

The bonds, referred above as “Yankee bonds”, contain a covenant requiring Minera Mexico to maintain a ratio of EBITDA to interest expense of not less than 2.5 to 1.0 as such terms are defined in the debt instrument. At December 31, 2020, Minera Mexico was in compliance with this covenant.

Between July 2005 and November 2012 the Company issued senior unsecured notes 6 times totaling $4.2 billion, as listed above. Interest on the notes is paid semi-annually in arrears. The notes rank pari passu with each other and rank pari passu in right of payment with all of the Company’s other existing and future unsecured and unsubordinated indebtedness. On April 20, 2015, the Company issued $2.0 billion of fixed-rate senior unsecured notes. This debt was issued in 2 tranches, $500 million due 2025 at an annual interest rate of 3.875% and $1.5 billion due 2045 at an annual interest rate of 5.875%. These notes are general unsecured obligations of the Company and rank equally with all of its existing and future unsecured and unsubordinated debt. Net proceeds are being used for general corporate purposes, including the financing of the Company´s capital investment program. The notes were issued with an underwriters’ discount of $20.2 million. Additionally, issuance costs of $11.8 million associated with these notes were paid and deferred. The unamortized balance of the discount and the costs are presented net of the carrying value of the debt issued and are amortized as interest expense over the life of the loan.

The indentures relating to the notes contain certain restrictive covenants, including limitations on liens, limitations on sale and leaseback transactions, rights of the holders of the notes upon the occurrence of a change of control triggering event, limitations on subsidiary indebtedness and limitations on consolidations, mergers, sales or conveyances. Certain of these covenants cease to be applicable before the notes mature if the Company obtains an investment grade rating. The Company obtained investment grade rating in 2005. The Company has registered these notes under the Securities Act of 1933, as amended. The Company may issue additional debt from time to time pursuant to certain of the indentures.

If the Company experiences a “Change of Control Triggering Event”, the Company must offer to repurchase the notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any. A Change of Control Trigger Event means a Change of Control (as defined) and a rating decline (as defined), that is, if the rating of the notes, by at least one of the rating agencies shall be decreased by 1 or more gradations.

At December 31, 2020, the Company was in compliance with the covenants of the notes.

On September 26, 2019, SCC’s subsidiary Minera Mexico S.A. de C.V. issued $1.0 billion of fixed-rate senior notes with a discount of $12.7 million. Additionally, issuance costs of $9.8 million associated with these notes were paid and

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

deferred. The unamortized balance of the discount and the costs are presented net of the carrying value of the debt issued and are amortized as interest expense over the life of the loan. This debt was issued in one tranche, due in 2050 at an annual interest rate of 4.5%. Interest on the notes is paid semi-annually in arrears. The Company intends to use the net proceeds from this offering (i) to finance Minera Mexico expansion program, including the Buenavista Zinc, Pilares and El Pilar projects, (ii) for other capital expenditures and (iii) for general corporate purposes.

The notes constitute general unsecured obligations of Minera Mexico. The notes were issued in an unregistered offering pursuant to Rule 144A and Regulation S under the Securities Act of 1933. The Company capitalized the costs associated with the issuance of this facility, which are included as part of the amortized cost of the long-term debt in the consolidated balance sheet.

In connection with the transaction, on September 26, 2019, Minera Mexico entered into an indenture with Wells Fargo Bank, National Association, as trustee, which provided for the issuance, and set forth the terms of the notes described above. The indenture contains covenants that limit Minera Mexico's ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of Minera Mexico's assets.

Expatriate Plan

The Company’s funding policy is to contribute amounts to the qualified plan sufficient to meet the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974 plus such additional amounts as the Company may determine to be appropriate.

Plan assets are invested in a group annuity contract with Metropolitan Life Insurance Company (“MetLife”). The Contract invests in the MetLife General Account Payment Fund (the "General Account") and the MetLife Broad Market Core Bond Fund (the “Bond Fund”) managed by BlackRock, Inc.

The General Account is broadly diversified across asset classes and backed by the total capital of MetLife.

The Bond Fund seeks to outperform the Bloomberg Barclays ® U.S. Aggregate Bond Index, net of fees, over a full market cycle. The Bond Fund invests in publicly traded, investment grade securities. These may include corporate securities, mortgage securities, treasuries and cash, agency securities, commercial mortgage backed securities and other investment vehicles adhering to the fund’s investment objectives. These investments are classified as Level 1 because they are valued using quoted prices of the same securities as they consist of instruments which are publicly traded.

Plan assets are invested with the objective of maximizing returns with an acceptable level of risk and maintaining adequate liquidity to fund expected benefit payments. The Company's policy for determining asset mix-targets to meet investment objectives includes periodic consultation with recognized third-party investment consultants.

The expected long-term rate of return on plan assets is reviewed annually, taking into consideration asset allocations, historical returns and the current economic environment. Based on these factors the Company expects its assets will earn an average of 4.00% per annum assuming its long-term mix will be consistent with its current mix.

Mexican Plan

Minera Mexico’s policy for determining asset mix targets includes periodic consultation with recognized third-party investment consultants. The expected long-term rate of return on plan assets is updated periodically, taking into consideration assets allocations, historical returns and the current economic environment. The fair value of plan assets is impacted by general market conditions. If actual returns on plan assets vary from the expected returns, actual results could differ.

The plan assets are managed by 3 financial institutions, Scotiabank Inverlat S.A., Banco Santander and GBM Grupo Bursatil Mexicano, S.A. 78% of the funds are invested in Mexican government securities, including treasury certificates and development bonds of the Mexican government. The remaining 22% is invested in common shares of Grupo Mexico. The plan assets are invested without restriction in active markets that are accessible when required and are therefore considered as level 1, in accordance with ASC 820 “Fair Value Measurement.”

These plans accounted for approximately 100% of benefit obligations. The following table represents the asset mix of the investment portfolio as of December 31:

Assumed health care cost trend rates can have a significant effect on amounts reported for health care plans. However, because of the size of the Company’s plan, a one percentage-point change in assumed health care trend rate would not have a significant effect.

Mexican Health Plan

For measurement purposes, a 4.5% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2020 and remains at that level thereafter.

An increase in other benefit cost trend rates have a significant effect on the amount of the reported obligations, as well as component cost of the other benefit plan. One percentage-point change in assumed other benefits cost trend rates would have the following effects:

Peruvian operations: The Company’s operations are subject to applicable Peruvian environmental laws and regulations. The Peruvian government, through the Ministry of Environment (“MINAM”) conducts annual audits of the Company’s Peruvian mining and metallurgical operations. Through these environmental audits, matters related to environmental obligation, compliance with legal requirements, atmospheric emissions, effluent monitoring and waste management are reviewed. The Company believes that it is in material compliance with applicable Peruvian environmental laws and regulations. Peruvian law requires that companies in the mining industry provide assurances for future mine closure and remediation. In accordance with the requirements of this law, the Company’s closure plans were approved by MINEM. See Note 10 “Asset retirement obligation,” for further discussion of this matter.

Air Quality Standards (“AQS”): In June 2017, MINAM enacted a supreme decree which defines new AQS for daily sulfur dioxide in the air. As of December 31, 2020, the Company maintains a lower daily average level of µg/m3 of SO2, 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 Descontamination Plans (“SDP”)

for environmentally impacted sites in each of its operation units (Toquepala, Cuajone and Ilo) with the assistance of consulting companies. The cost of these SDPs are not material, either individually or in aggregated form, for the financial statements of the Company.

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

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

In 2011, the General Law was amended to provide an individual or entity the ability to contest administrative acts, including environmental authorizations, permits or concessions granted, without the need to demonstrate the actual existence of harm to the environment as long as it can be argued that the harm may be caused. In addition, in 2011, amendments to the Civil Federal Procedures Code (“CFPC”) were enacted, which established 3 categories of collective actions under which a group of 30 or more individuals can be considered sufficient to prove a “legitimate interest” to file civil actions for injuries derived from alleged violations of environmental, consumer protection, financial services and economic competition laws and to seek restitution or economic compensation for the alleged injuries or the suspension of the activities which allegedly generated 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. The law establishes general guidelines for actions to be considered to likely cause environmental harm. If a possible determination regarding harm occurs, environmental clean-up and remedial actions sufficient to restore environment to a pre-existing condition should be taken. Under this law, if restoration is not possible, compensation measures should be provided. Criminal penalties and monetary fines can be imposed under this law.

On February 2019, the Mexican Supreme Court confirmed the constitutionality of an ecological tax on extractive activities developed in the state of Zacatecas, which taxes the environmental remediation actions; emissions of certain gases to the atmosphere; emissions of pollutant substances to the soil or water; and waste storage within the state territory. 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 3 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 and 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 appropriate 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

On Friday, July 19, 2019, PROFEPA revisited the facilities to carry out a second inspection, declaring a partial temporary shutdown that affected only 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 4 times (for a two-year period each time).

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 certainty that the operation is in strict compliance with environmental regulations. The Company expects the environmental authorities to suspend the partial temporary shutdown, once they resolve their concerns. Currently, the Company does not expect any impact on its operations. As of December 31, 2020, the matter is pending resolution.

Litigation matters:

Peruvian operations

The Tia Maria Mining Project

There are 5 lawsuits filed against the Peruvian Branch of the Company related to the Tia Maria project. The lawsuits seek (i) to declare null and void the resolution that approved the Environmental Impact Assessment of the project; (ii) the cancellation of the project and the withdrawal of mining activities in the area; (iii) to declare null and void the mining concession application for the Tia Maria project; and (iv) to declare null and void the resolution that approved the construction license. The lawsuits were filed by Messrs. Jorge Isaac del Carpio Lazo (filed May 22, 2015), Ernesto Mendoza Padilla (filed May 26, 2015), Juan Alberto Guillen Lopez (filed June 18, 2015), Junta de Usuarios del Valle del Tambo (filed April 30, 2015), and Gobierno Regional de Arequipa (filed December 16, 2019).

The del Carpio Lazio case was rejected by the court of first instance on November 14, 2016. The plaintiff filed an appeal before the Superior Court on January 3, 2017. On January 9, 2018, the lawyers of both parties presented their respective positions before the Appellate Court. On March 8, 2018, the Appellate Court issued its final decision, which upheld the first instance ruling. On April 27, 2018, the plaintiff filed an extraordinary appeal before the Supreme Court. As of December 31, 2020, the case remains pending resolution.

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. As of December 31, 2020, the case remains pending resolution.

The Guillen Lopez case is currently before the lower court. On July 19, 2019, the oral arguments took place. On January 7, 2020, the Judge decided to suspend the proceeding until the del Carpio Lazio case is concluded. Therefore, as of December 31, 2020, the case remains pending resolution.

The Junta de Usuarios del Valle del Tambo case is currently before the lower court. On May 2016, the Company was included in the process, after the Ministry of Energy and Mines filed a civil complaint. On March 6, 2019, the Company was formally notified of the lawsuit and answered the complaint on March 20, 2019. On July 8, 2019, the Company

requested the suspension of the proceeding until the del Carpio Lazio case is concluded. As of December 31, 2020, the case remains pending resolution.

The Gobierno Regional de Arequipa case is currently before the lower court and the Company answered the complaint on September 15, 2020. As of December 31, 2020, the case remains pending resolution.

The Company asserts that these lawsuits are without merit and is vigorously defending against them. The potential contingency amount for these cases cannot be reasonably estimated by management at this time.

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

In 2012, the Pasto Grande Project, an entity of the Regional Government of Moquegua, filed a lawsuit against SCC’s Peruvian Branch alleging property rights over a certain area used by the Peruvian Branch and seeking the demolition of the tailings dam where SCC’s Peruvian Branch has deposited its tailings from the Toquepala and Cuajone operations since 1995. The Peruvian Branch has had title to use the area in question since 1960 and has, since 1995, constructed and operated the tailings dams with proper governmental authorization. Upon a motion filed by the Peruvian Branch, the lower court has included MINEM as a defendant in this lawsuit. MINEM has answered the complaint and denied the validity of the claim. As of December 31, 2020, the case was pending resolution without further developments. SCC’s Peruvian Branch asserts that the lawsuit is without merit and is vigorously defending against it. The amount of this contingency cannot be reasonably estimated by management at this time.

The Accidental Spill at Buenavista Mine of 2014

In relation to the 2014 accidental spill of copper sulfate solution that occurred 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 December 31, 2020.

Through the first half of 2015, 6 collective action lawsuits were filed in federal courts in Mexico City and Sonora against 2 subsidiaries of the Company seeking economic compensation, clean up and remedial activities in order to restore the environment to its pre-existing conditions. NaN of the collective action lawsuits have been dismissed by the court. As of December 31, 2020, 4 lawsuits continue in process: 3 were filed by Acciones Colectivas de Sinaloa, A.C. and one, by Defensa Colectiva, A.C.; requesting precautionary measures about construction of facilities for monitoring public health services and prohibiting the closure of the Rio Sonora Trust.

Similarly, during 2015, 8 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, 3 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 NaN 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

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 3 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 December 31, 2020, NaN cases remain pending resolution.

In 2015, 4 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 1 subsidiary of the Company; and (iv) the alleged inactivity of the authorities with regard of the spill in August 2014. The plaintiffs of these lawsuits are: Francisca Garcia Enriquez, et al filed 2 lawsuits, Francisco Ramon Miranda, et al and Jesus David Lopez Peralta et al. In the third quarter of 2016, 4 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 2 additional constitutional lawsuits that were filed against SEMARNAT by Norberto Bustamante et al. Regarding 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, with no material effects to BVC’s operations. SEMARNAT has carried out the consultation ordered by the Supreme Court. As a result, has informed the corresponding Judge about its compliance with the resolution, in which BVC was imposed additional measures of environmental impact prevention, such as: (i) the building of at least 3 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, for which six months are 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 that are imposed. The foregoing does not impact BVC’s operations. Likewise, it is noted that 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 December 31, 2020, 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 contracts, the mineral contracts, the transportation contracts, and the 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.

As of February 2021, because the Company has not reached a conclusion as to whether an unfavorable outcome is either probable or remote, the Company expresses no opinion as to the likelihood of an unfavorable outcome or the amount or range of any possible loss to the Company.

Labor matters:

Peruvian operations: 66% of the Company's 4,739 Peruvian employees were unionized at December 31, 2020. Currently, there are 6 separate unions, 1 large union and 5 smaller unions. In June 2018, the Company signed a three-year collective bargaining agreement with one of the smaller unions. This agreement includes, among other things, annual salary increases of 5% for each year starting September 2018, and a signing bonus of S/ 45,000 (approximately $13,600) which was recorded as labor expense. In August 2018, the Company signed a three-year collective bargaining agreement with 3 additional unions. This agreement includes, among other things, annual salary increases of 5% for each year starting December 2018, and a signing bonus of S/ 45,000 (approximately $13,600) which was recorded as labor expense. In March 2019, the Company resolved pending issues by means of an arbitration with 1 additional union. The arbitral award included annual salary increases of 5% for each year starting September 2018, and a signing bonus of S/45,000 (approximately $13,600) which was recorded as labor expense in the first quarter of 2019.

In May 2019, an arbitration resolved pending issues with the remaining union. The arbitral award included a salary increase of 5.5% beginning in September 2018 and a bonus of S/16,000 (approximately $4,800) for the one-year agreement, which was recorded as labor expense in the second quarter of 2019. In November 2019, the Company signed a collective bargaining agreement for three years with the same union. This agreement included, among other things, a salary increase of 5% for each year starting in September 2019 and a bonus of S/45,000 (approximately $13,300), which was recorded as labor expenses in the fourth quarter of 2019.

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 and the case was still pending resolution as of December 31, 2020. The Company is working on a rehabilitation plan to restore operations at the San Martin mine with a budget of $97.7 million. As of December 31, 2020, the plan is underway with a total expense of $86.4 million.

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 December 31, 2020, the case remains pending resolution without further developments.

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

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

Other legal matters:

The Company is involved in various other legal proceedings incidental to its operations, but the Company does not believe that decisions adverse to it in any such proceedings, individually or in the aggregate, would have a material effect on its financial position or results of operations.

Other commitments:

Peruvian Operations

Tia Maria:

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

On July 15, 2019, anti-mining groups staged a violent demonstration affecting economic as well as other activities in the Islay province. These actions were followed by the filing of 3 complaints, sponsored by groups opposing the Tia Maria project, with the Mining Council, which is the Peruvian administrative authority responsible for ruling on these complaints. The Mining Council temporarily suspended the construction permit on August 8, 2019. On October 7, 2019, as part of the process, the Mining Council conducted a hearing to hear the complaints and the Company’s position. On

October 30, 2019, the Mining Council of the Peruvian Ministry of Energy and Mines ratified the construction permit for the Tia Maria project.

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

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

Tia Maria’s project budget is approximately $1.4 billion, of which $338.8 million has been invested through December 31, 2020. 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, release no 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 mineralized material of 1,150 million tons and a copper grade of 0.63%. It is expected to produce 225,000 tons of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years.

The Company paid $12.5 million at the signing of the contract. The balance of $387.5 million will be paid if the Company decides to develop the project and it is not a present obligation.

Corporate Social Responsibility:

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

Tacna Region: In connection with the Toquepala concentrator expansion, the Company has committed to fund various social and infrastructure improvement projects in Toquepala's neighboring communities. The total amount committed for these purposes is S/ 445.0 million (approximately $122.8 million).

As the Toquepala expansion project has been completed, the Company considers that these commitments constitute present obligations of the Company and consequently has recorded a liability of $41.3 million in its consolidated financial statements as of December 31, 2020.

In addition, the Company has committed S/ 69.7 million (approximately $19.2 million) for the construction of 1 infrastructure project 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.

Directors’ Stock Award Plan:

The Company established a stock award compensation plan for certain directors who are not compensated as employees of the Company. Under this plan, participants received 1,200 shares of common stock upon election and 1,200 additional shares following each annual meeting of stockholders thereafter. 600,000 shares of Southern Copper common stock have been reserved for this plan. On April 26, 2018, the Company’s stockholders approved a five-year extension of the Plan until January 28, 2023 and an increase of the shares award from 1,200 to 1,600. The fair value of the award is measured each year at the date of the grant. In 2020 and 2019 the stock-based compensation expense under this plan equaled $0.4 million for each of these years.

Employee Stock Purchase Plan:

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 established at 38.44 Mexican pesos (approximately $1.86) 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.

Executive Stock Purchase Plan:

Grupo Mexico also offers a stock purchase plan for certain members of its executive management and the executive management of its subsidiaries and certain affiliated companies. Under this plan, participants will receive incentive cash bonuses which are used to purchase shares of Grupo Mexico which are deposited in a trust.

Retained earnings:

As part of the settlement of claims brought on behalf of the Company and its shareholders against Grupo Mexico, AMC and certain current and former directors (together with Grupo Mexico and AMC, the ‘‘Defendants’’) a dividend of $0.44428 per share was paid on February 21, 2019 to shareholders of record at the close of business on February 11, 2019, other than the Defendants. The settlement dividend, totaling $36.5 million was an obligation of Grupo Mexico and

AMC and therefore, has been funded by them. In addition, Grupo Mexico and AMC paid $13.5 million of legal fees.

Non-controlling interest:

For all the years presented, in the consolidated statement of earnings the income attributable to non-controlling interest is based on the earnings of the Company's Peruvian Branch.

The non-controlling interest of the Company’s Peruvian Branch is for investment shares. These shares were generated by legislation in place in Peru from the 1970s through 1991; such legislation provided for the participation of mining workers in the profits of the enterprises for which they worked. This participation was divided between equity and cash. The investment shares included in the non-controlling interest on the consolidated balance sheets reflect outstanding equity distributions made to the Peruvian Branch’s employees.

In prior years, the Company acquired some Peruvian investment shares in exchange for newly issued common shares of the Company and through purchases at market value. These acquisitions were accounted for as purchases of non-controlling interests. The excess paid over the carrying value was assigned to intangible assets and is being amortized based on production. As a result of these acquisitions, the remaining investment shareholders hold a 0.71% interest in the Peruvian Branch and are entitled to a pro rata participation in the cash distributions made by the Peruvian Branch. The shares are recorded as a non-controlling interest in the Company's financial statements.

NOTE 15—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 that provides information about the carrying amounts and estimated fair values of other financial instruments that are not measured at fair value in the consolidated balance sheet as of December 31, 2020 and December 31, 2019 (in millions):

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

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

NOTE 18—SEGMENT AND RELATED INFORMATION:

Company management views Southern Copper as having 3 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 3 reportable segments identified are groups of mines, each of which constitute an operating segment, with similar economic characteristics, type of products, processes and support facilities, similar regulatory environments, similar employee bargaining contracts and similar currency risks. In addition, each mine within the individual group earns revenues from similar type of customers for their products and services and each group incurs expenses independently, including commercial transactions between groups.

Intersegment sales are based on arm’s length prices at the time of sale. These may not be reflective of actual prices realized by the Company due to various factors, including additional processing, timing of sales to outside customers and transportation cost. Added to the segment data is information regarding the Company’s sales. The segments identified by the Company are:

1.Peruvian operations, which include the Toquepala and Cuajone mine complexes and the smelting and refining plants, including a precious metals plant, industrial railroad and port facilities that service both mines. The Peruvian operations produce copper, with production of by-products of molybdenum, silver and other material.

2.Mexican open-pit operations, which include La Caridad and Buenavista mine complexes and the smelting and refining plants, including a precious metals plant and a copper rod plant and support facilities that service both mines. The Mexican open-pit operations produce copper, with production of by-products of molybdenum, silver and other material.

3.Mexican underground mining operations, which include 5 underground mines that produce zinc, copper, silver and gold, and a zinc refinery. This group is identified as the IMMSA unit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Peruvian operations include 2 open-pit copper mines whose mineral output is transported by rail to Ilo, Peru where it is processed at the Company’s Ilo smelter and refinery, without distinguishing between the products of the 2 mines. The resulting product, anodes and refined copper, are then shipped to customers throughout the world. These shipments are recorded as revenue of the Company’s Peruvian mines.

The Mexican open-pit segment includes 2 copper mines whose mineral output is processed in the same smelter and refinery without distinguishing between the products of the 2 mines. The resultant product, anodes and refined copper, are then shipped to customers throughout the world. These shipments are recorded as revenues of the Company’s Mexican open-pit mines.

The Company has determined that it is necessary to classify the Peruvian open-pit operations as an operating segment that is separate from the Mexican open-pit operations due to the very distinct regulatory and political environments in which they operate. The Company’s Chief Operating Decision Maker (“CODM”) must consider the operations in each country separately when analyzing results of the Company and making key decisions. The open-pit mines in Peru must comply with stricter environmental rules and must deal with a political climate that has a very distinct vision of the mining industry than that seen in Mexico. In addition, the collective bargaining agreement contracts are negotiated differently in each of the countries. These key differences result in the Company taking varying decisions with regard to open-pit operations in the 2 countries.

The IMMSA segment includes 5 mines whose minerals are processed in the same refinery. Sales of product from this segment are recorded as revenues of the Company’s IMMSA unit. While the Mexican underground mines are subject to a regulatory environment that is very similar to that applicable to Mexican open-pit mines, the nature of the products and processes of the 2 Mexican operations vary considerably. These differences cause the Company’s CODM to take a very different approach when analyzing results and making decisions regarding the 2 Mexican operations.

Financial information is regularly prepared for each of the 3 segments and the results of the Company’s operations are regularly reported to the 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.

A Company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Compensation Objectives:

Our objectives in compensating our Named Executive Officers are to encourage the achievement of our business objectives and superior corporate performance by our Named Executive Officers. Our business objectives include increasing production and lowering costs in a safe environment, maintaining customer satisfaction, market leadership, and enhancing stockholder value. The principal objective of our compensation practices is to reward and retain executives with key core competency critical to our long-term management strategy. We reward results rather than on the basis of seniority, tenure or other entitlement. We believe that our executive compensation practices align compensation with our business values and strategy.

What Is Our Compensation Designed to Reward?

Our compensation is designed to reward our Named Executive Officers for their efforts and dedication to us and for their ability to attract, motivate, and energize a high-performance leadership team, encouraging innovation in our employees, conceptualizing key trends, evaluating strategic decisions, and continuously challenging our employees to sharpen their vision and excel in performing their duties. We also reward our Named Executive Officers for achieving the business plans that the Board of Directors has approved, for unique accomplishments and achievements, and for their leadership in managing our affairs in the locations in which we operate, mainly Peru and Mexico.

Why We Choose to Compensate Our Executives?

We choose to compensate our employees, including our Named Executive Officers, to grant them basic economic security at levels consistent with competitive local practices. We believe that the compensation we provide to our employees, including our Named Executive Officers, permits us to retain our highly skilled and qualified workforce.

We are required to grant our employees certain elements of compensation mandated by Peruvian and Mexican law, as applicable. Peruvian and Mexican law require us to pay salaries to our employees commensurate with each employee’s job requirements and the experience and skills of every employee. The level of each salary is determined by us. We pay salaries and bonuses to reward and retain our excellent employees, including our Named Executive Officers. We also provide other Company sponsored benefits to remain competitive in the Peruvian and Mexican labor markets and to reward our employees, including our Named Executive Officers. The Peruvian five percent increase in monthly salary for each five years of service evolved as a benefit bargained by our labor unions and was later extended to all salaried employees. The Peruvian vacation bonus and vacation travel benefits evolved from our practice of compensating expatriate employees who worked in Peru and was later extended to certain key salaried employees, including Named Executive Officers working in Peru.

How Do We Determine Each Element of Compensation?

The Company’s management team and Compensation Committee make the decisions to grant salary increases and bonuses for the Named Executive Officers of the Company after a thorough analysis of numerous factors, including among others, the responsibilities and performance of each Named Executive Officer measured in the areas of production, safety and environmental responsiveness (both individually and as compared to other officers of the Company). In addition, management and the Compensation Committee consider years of service, future challenges and objectives, the potential contributions of each officer to the future success of our Company, total executive compensation, and the Company’s overall financial performance. Peruvian and Mexican law requires us to pay salaries to our employees commensurate with each employee’s job requirements, experience and skills, and to share 8% of the annual pre-income tax profits of our Peruvian Branch with our Peruvian employees and 10% of the annual pre-income tax profits of our Mexican operation with our Mexican employees.

When we increase base salaries for our Named Executive Officers, we use a tabulation, which is revised every year to adjust for inflation in Mexico and Peru. The base salary increases take into account the individual’s position, as well as his/her results and job performance in the relevant year. Base salary increases are not granted indiscriminately to employees. Instead, they are granted to reward individuals who facilitate the achievementDeputy Director of the Company’s corporate goals. Our corporate goals include increasing production and lowering costs in a safe environment, maintaining customer satisfaction and market leadership, and enhancing stockholder value.

We promote our Named Executive Officers from within our organization and we hire new executives through recruiters. We also use Human Resources consultants, such as the Hay Group from time to time, which provide us with comparative salary dataInternal Control for the sought position extracted from their database relating to comparable companies in Mexico and Peru. The information provided from time to time by the Human Resources consultants is not customized for the Company. Although our Compensation Committee has the authority and necessary funding to engage compensation and other advisers, it has not engaged such advisers in the period 2016-2019.


The salaries provided by the Human Resources consultants from their database are used by us as an indication of the market salaries prevailing in Peru and Mexico. In Peru, the consultants provide us with salaries, which they report were paid or offered to potential candidates by mining companies operating in Peru. The reports of the Human Resources consultants have included in the past salary information from Peruvian companies or Peruvian subsidiaries, such as the following: Xstrata Tintaya, S.A., Minera Yanacocha Peru, Hochschild Mining, plc, Compañía Minera Antamina, S.A., Minera Barrick Misquichilca, S.A., Minsur S.A., Gold Fields La Cima, S.A.A., and Sociedad Minera Cerro Verde, S.A.A. In Mexico, the consultants have provided us with salaries, which they reported were paid or offered to potential candidates by mining companies operating in Mexico. The reports of the Human Resources consultants have included in the past salary information  from Mexican companies or Mexican subsidiaries, such as the following: Newmont Mining Corporation, Pan American Silver Corporation, Industrias Peñoles, S.A.B. de C.V., Grupo Bacis, S.A. de C.V., Mexicoro, S.A. de C.V., Minera BHP Billiton, S.A. de C.V., and Minera Phelps Dodge de Mexico S. de R.L. de C.V. The above listing is for illustration purposes only, as the list of companies used by Human Resources consultants may vary from year to year. Additionally, we have not made an independent verification of the salary information reported by the Human Resources consultants.

We factor this comparative salary information into our decision making process by targeting our personnel compensation policies, including the compensation of the Named Executive Officers, generally toward the median and third quartile of market compensation.

In 2017 and 2018, the reported median base salaries for S&P 500 chief executives were $1,150,000 and $1,200,000, respectively. Although the 2019 report was not available at the time of print, we believe that the median base salary for 2019 would continue the same trend as last year. Even though we are not one of the constituent companies of the S&P 500 index, we have a market capitalization that would permit us to compare ourselves with the companies that constitute the index. We have compared the 2017 and 2018 salaries of Mr. Oscar González Rocha with the reported median base salaries of S&P 500 chief executives and determined that the salaries paid to him are below the reported median. Similarly, we believe that the salary of Mr. Oscar González Rocha in 2019 will be below the reported median for 2019.

The amount and formula applicable to the other benefits are mandated by Peruvian and Mexican law for all salaried employees. We also sponsor programs to recruit and retain qualified employees working in Peru and Mexico. 

Under Section162(m)of the Internal Revenue Code of 1986, as amended, we may not deduct, with certain exceptions, compensation in excess of $1 million to the Principal Executive Officer, the Principal Financial Officer and our three other most highly compensated officers (other than the Principal Executive Officer or the Principal Financial Officer) as required to be reported in our proxy statement. We do not believe that Section162(m)will have any immediate material impact on us because, among other things, our officers’ salaries do not enter into the calculation of US source taxable income. We will, however, continue to monitor our executive compensation programs to ensure their effectiveness and efficiency in light of our needs, including Section 162(m).

How Does Each Element and Our Decisions Regarding That Element Fit Into Our Overall Compensation Objectives and Affect Decisions Regarding Other Elements?

We take into account each element of compensation to determine the overall compensation of our executives. It is our practice to grant relatively small salary increases commensurate with the cost of living increases in Peru and Mexico and tailor the amount of the incentive cash payments to balance the amounts of compensation mandated by Peruvian and Mexican law, principally the amounts received as profit participations. In years in which the profit participation is high, the bonus or incentive cash payment will be reduced. In years in which the profit participation is relatively modest, if our financial conditions permit, we tend to increase the amount paid in cash incentives. The payment of bonuses is discretionary and we do not necessarily pay bonuses every year. The payment of bonuses and the amount of any such bonuses depend, among other things, on our financial performance, our intensive capital investment plan, our projected future cash flow generation from operations, and our liquidity in general. We do not provide compensation tied to specific pre-determined individual or Company performance criteria or long-term incentive compensation. The discretionary cash bonus payments granted to our executives and non-executive employees are not based on pre-established performance targets or on targets that have been previously communicated to the executives or the employees. The granting of specific awards and the amount of each award are discretionary and substantially uncertain until we decide to award them. Without limiting this, from time to time, larger discretionary cash bonuses are granted to certain of our Named Executive Officers in recognition of said Named Executive Officers' performance during the year and to reward them for their leadership, vision and focus.


Disclosure on Result of the Non-Binding Advisory Vote on Executive Compensation (“Say-on-Pay”):

Every year we provide our Common Stockholders with the opportunity to cast an advisory vote on executive compensation. At our annual meeting of stockholders held on April 25, 2019, 99.60% of the votes cast on said proposal were voted in favor of the proposal. Our Compensation Committee and management team believe this affirms our Common Stockholders’ support of our approach to executive compensation, therefore no material changes were made to our approach. We will continue to consider the outcome of future advisory votes on executive compensation when making future compensation decisions for the Named Executive Officers.  In addition, a substantial majority of the votes cast on the Say-on-Pay frequency vote proposal in 2017 were in favor of holding a Say-on-Pay vote every year, and as a result, we will continue to hold this vote on an annual basis.

Summary:

Our compensation practices are designed to comply with the requirements of Peruvian and Mexican law and with our goals and objectives to retain our key executives and reward them appropriately for their positive results. We continue to monitor our compensation practices to remain competitive in the marketplace and to reward our executives for results that are consistent with the long-term interest of our Company and our stockholders.

Peruvian Compensation Practices:

Our Peruvian compensation practices take into account many factors, including individual performance and responsibilities, years of service, elements of compensation mandated by Peruvian law, future challenges and objectives, contributions to the future success of our Company, the executive’s total compensation, and our financial performance. We may also look at the compensation levels of comparable companies. 

Our Named Executive Officers in Peru, Messrs. Oscar González Rocha, Raul Jacob and Edgard Corrales, and Ms. Lina Vingerhoets received cash-based compensation, which is currently paid. The cash-based compensation has two principal components: base salary and bonus, which are discretionary, and compensation mandated by Peruvian law. We also sponsor programs to recruit and retain qualified employees working in Peru. Additionally, Grupo Mexico offers certain key employees, including our Named Executive Officers, eligibility under stock purchase plans. See the description of these plans under “Stock Purchase Plansdivision of Grupo Mexico” below.

The payment of bonuses and the amount of same depend, among other things, on our financial performance, our intensive capital investment plan, our future cash flow generation from operations, and our liquiditybefore this, he held several positions in general.

We do not provide compensation tied to specific pre-determined individual or Company performance criteria or long-term incentive compensation.

The cash incentive payments granted to our Named Executive Officers are not based on pre-established performance targets or on targets that have been previously communicated to the executives. The granting of the award and the amount of each award are discretionary and substantially uncertain until we decide to award them.

All our Peruvian employee compensation is denominated in Peruvian Soles. We convert the Peruvian Soles into U.S. dollars using the average exchange rate for the applicable period.

Stock Options:

We have not granted stock options or other equity incentive awards to any of our Named Executive Officers since 2000 in Peru. The Stock Incentive Plan, under which options and stock awards could have been granted, expired by its terms on January 1, 2006.


Stock Purchase Plans of Grupo Mexico:

Grupo Mexico offers certain eligible key employees, including our Named Executive Officers, a stock purchase plan (the “Employee Stock Purchase Plan”) through a trust that acquires shares of Grupo Mexico for future sales to our employees, and employees of our subsidiaries and certain affiliated companies. Sales are at the approximate fair market value at the date of grant. Every two years employees will be able to purchase shares subscribed for purchase 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, Grupo Mexico will grant the participant a bonus of one share for every ten shares purchased by the employee. If Grupo Mexico pays dividends on shares during the eight year period, the participant 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 dividends payable with respect to the purchased shares will be used to reduce the remaining liability owed for such shares. No stock bonuses under the Employee Stock Purchase Plan were granted to our Named Executive Officers in 2019.

Grupo Mexico also offers a stock purchase plan for certain members of its executive management and the executive management of its subsidiaries and certain affiliateddifferent companies (“Executive Stock Purchase Plan”). Under this plan, participants receive incentive cash bonuses that are used to purchase shares of Grupo Mexico and which are deposited in a trust.  Mr. Oscar González Rocha received a discretionary cash bonus of $416,948 in 2019, which was used to purchase shares under this plan.  This bonus is reflected in the Summary Compensation Table under the Bonus column.

Pension Plan:

The Company has two non-contributory defined benefit pension plans covering former salaried employees in the United States and certain former employees in Peru. Messrs. González Rocha, Jacob, and Corrales and Ms. Vingerhoets are not covered by our non-contributory retirement plans. They are covered by the Peruvian private pension system (“AFP”), a mandatory pension system. As required by Peruvian law, we retain every month a percentage of their salary and deposit the amount into their individual AFP accounts. The percentage of the monthly salary retained and deposited varies each year and has ranged from 8% to 10% over the years. Employees received in 1995 a 13.53% salary increase to compensate them for the new deduction established by Peruvian law to participate in the mandatory pension system. Messrs. Jacob and Corrales and Ms. Vingerhoets received a payment of $6,159, $2,290 and $2, 098, respectively, in 2019 pursuant to the requirements of the AFP law. These payments are included in the compensation reported for Messrs. Jacob and Corrales and Ms. Vingerhoets. 

Severance Benefits:

We do not have corporate plans providing severance benefits to our Named Executive Officers in Peru. Our Named Executive Officers only receive severance benefits provided by Peruvian law. If the employee is terminated by us and he or she has a fixed-term employment agreement, Peruvian law requires that we pay the employee’s salary for the remaining of the term of his or her employment agreement. Peruvian law also provides that if the employee has been dismissed without cause, he or she is entitled to an amount equal to one and one-half times his or her monthly salary for each year of service up to a maximum of eight years or the equivalent of twelve months of salary. Peruvian law also provides that at the termination of employment, an employee will be able to withdraw the full amount of the compensation for the years of service, known as CTS (“Compensación por Tiempo de Servicios”) in Peru described below. Our Named Executive Officers in Peru do not have change of control employment agreements. Our Named Executive Officers in Peru, including Messrs. Jacob and Corrales and Ms. Vingerhoets, do not have employment agreements. However, Mr. Oscar González Rocha, our Chief Executive Officer, who is an expatriate, has an employment agreement described below.

Expatriate Employees:

Pursuant to Peruvian laws concerning expatriate employees, Mr. Oscar González Rocha entered into an employment agreement. The employment agreement is in effect for a term of one year and may be extended for additional periods. In accordance with the terms of the employment agreement, the Company has agreed to provide Mr. Oscar González Rocha (and any other expatriate employees) with benefits as required by Peruvian law. Under the employment agreement, Mr. Oscar González Rocha may resign at any time by providing us with 30 days notice. The employment agreement also provides that we may dismiss Mr. Oscar González Rocha for serious offenses as established by Peruvian law. Terminated employees are also entitled to receive severance benefits as required by Peruvian law. Our non-Peruvian contract employees and their dependents receive travel benefits to return to their home country at the end of each year and return to Peru at the commencement of each year of the contract. Additionally, this benefit includes travel to their home country at the termination of the contract.

None of the Peruvian Named Executive Officers received salary increases in 2019. The minor differences in the comparison of the 2019 and 2018 salaries for Messrs. González Rocha, Jacob and Corrales and Ms. Vingerhoets are due to foreign exchange conversion rates. The Company's functional currency is the U.S. dollar and salaries, as are all significant portions of our Peruvian operating costs, are denominated in Peruvian Soles. Accordingly, when inflation and currency devaluation/appreciation of the Peruvian currency occur reported salaries can be affected. Mr. Oscar González Rocha’s base salary at the commencement of his services with us is reflected in an employment agreement mandated by Peruvian law. In general, the base salaries of our Named Executive Officers in Peru follow the guidelines of salaries of other key employees of the Company.

Additionally, as compensation for years of service or CTS, Peruvian law requires a deposit of one twelfth of an employee’s annual salary, vacation, travel, Independence holidays, Christmas, dependents and service award bonus, each year, for each employee (whether Peruvian or expatriate) working in Peru, as applicable. This amount is deposited in a local bank of the employee’s choosing, in an individual account, which accrues interest paid by said bank. For all legal purposes, the chosen bank acts as trustee of the deposited amounts. The CTS funds can only be fully withdrawn when the employee terminates employment.

In 2019, we deposited for Messrs. González Rocha, Jacob and Corrales and for Ms. Vingerhoets, $99,286, $19,198, $18,936 and $12,478, respectively, as CTS compensation.

Hedging Policy

On March 8, 2019, the SEC adopted final rules that require companies to disclose any practices or policies regarding the ability of employees and directors to engage in certain hedging transactions with respect to the Company’s securities. The SEC rules do not require companies to adopt new hedging policies or amend previously approved hedging policies. The Securities Law Compliance Policy of the Company, approved by the Board of Directors on April 23, 2009, provides the following hedging policy:

Hedging

Certain forms of hedging or monetization transactions (such as zero-cost collars) are complex transactions that can present unique insider trading risks. Therefore, the Company strongly discourages board members, officers, employees, and agents covered by this Policy from engaging in such transactions. Any such person wishing to enter into such an arrangement must first pre-clear the proposed transaction with the General Counsel, Secretary or Assistant Secretary of SCC, and it is strongly recommended that such person consult with his or her broker/financial advisor and tax advisor. Any request for pre-clearance of a hedging or similar arrangement must be submitted to the General Counsel, Secretary or Assistant Secretary of SCC at least two weeks prior to the proposed execution of documents evidencing the proposed transaction and must set forth a justification for the proposed transaction.

Pay Ratio Disclosure

As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC has adopted a rule requiring us to disclose a ratio of total annual compensation of our median employee to total annual compensation of our CEO. Based on the methodology described below, the compensation of our median employee in 2019 was $33,321 and compensation to our CEO was $1,639,870, resulting in a ratio of CEO pay to median employee pay for fiscal year 2019 of 49:1.

We used our entire global employee population, other than the CEO, as of a determination date of December 31, 2019 to estimate the median employee. For estimating the median employee, we used a Consistently Applied Compensation Measure (CACM) of annual base salary for 2019 with values converted into U.S. dollars based on the average monthly exchange rate for 2018. We compiled annual base salary data for all employees and then selected our median employee from a group of employees with a salary within +/-1% of the median employee under the CACM. Our median employee is a full-time, hourly employee based in Mexico. After identifying the median employee, we calculated annual total compensation for this employee using the same methodology we use for our named executive officers as disclosed in the Summary Compensation Table.

Our pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. Because the SEC rules allow for different methodologies for determining the ratio, and because work force demographic can vary across companies, the estimated ratio should not be compared against other publicly-traded companies. There have been no changes that we reasonably believe would significantly affect the pay ratio disclosure set forth herein.

Compensation Policies and Practices and Risk

Our Peruvian and Mexican executive officers and non-executive employees receive cash-based compensation, which is currently paid. The cash-based compensation has two principal components: base salary and bonus, which are discretionary, and compensation mandated by Peruvian and Mexican law. We also sponsor programs to recruit and retain qualified employees working in Peru and Mexico.


The payment of bonuses is discretionary and we do not necessarily pay bonuses every year. The payment of bonuses and the amount of the same depend on numerous factors, including among others, our financial performance, our intensive capital investment plan, our future cash flow generation from operations, and our liquidity in general. We do not provide compensation tied to specific pre-determined individual or Company performance criteria or long-term incentive compensation. The cash incentive payments granted to our executives and non-executive employees are not based on pre-established performance targets or on targets that have been previously communicated to the executives or the employees. The granting of specific awards and the amount of each award are discretionary and substantially uncertain until we decide to award them.

The decisions to grant salary increases and bonuses for the Named Executive Officers of the Company and for non-executive employees are made by our management team and our Compensation Committee after a thorough analysis of numerous factors, including among others, the responsibilities and performance of each Named Executive Officer or employee measured in the areas of production, expansions and project developments, safety and environmental responsiveness (both individually and as compared to other officers or employees of the Company). It is our practice to grant relatively small salary increases to our Named Executive Officers commensurate with the cost of living increases in Peru and Mexico and tailor the amount of the incentive cash payments to balance the amounts of compensation mandated by Peruvian and Mexican law, principally the amounts received by the Named Executive Officers as profit participations. Generally, in years in which the profit participation amounts paid to Named Executive Officers are high, the bonus or incentive cash payments will be lower than in years in which the profit participation amounts are relatively modest. In such years, where the profit participation amounts are modest, if our financial conditions permit, we tend to increase the amount paid in cash incentives. Without limiting this, from time to time larger discretionary cash bonuses are granted to our Named Executive Officers in recognition of a particular Named Executive Officer’s performance during the year and to reward him for his leadership, vision and focus. The Company’s compensation policies or practices do not vary significantly from the Company’s overall risk and reward structure, inasmuch as we do not offer performance-based bonuses or incentive awards which occur significantly before receipt of anticipated income or expiration of associated risk to the Company.  We do not have business units that account for a significant portion of the Company’s risk profile or compensation policies and practices that vary for a particular business unit.  We continuously monitor our compensation policies and practices to avoid risk-taking by executive and non-executive employees to increase their compensation.

Item 13. Certain Relationships and Related Transactions, and Director Independence

Related Party Transactions

In 2019, we had entered into certain transactions in the ordinary course of business with parties that are controlling stockholders or their affiliates. These transactions include the lease of office space, air and railroad transportation, construction services, energy supply and other products and services related to mining and refining. We lend and borrow funds among affiliates for acquisitions and other corporate purposes. These financial transactions bear interest and are subject to review and approval by senior management, as are all related party transactions.

Grupo Mexico, our ultimate parent and our majority indirect stockholder, and its affiliates, provide various services to us directly or indirectly through subsidiaries. In 2019, these services were primarily related to accounting, legal, tax, financial, treasury, human resources, price risk assessment and hedging, purchasing, procurement and logistics, sales and administrative and other support services. In 2018 AMMINCO Apoyo Administrativo, S. A. de C. V. (“AMMINCO”), a subsidiary of Grupo Mexico, began providing such services to our Peruvian operations. We pay Grupo Mexico and AMMINCO for these services. The total amount paid by us to Grupo Mexico and AMMINCO for such services in 2019 was $27.8 million. The Company received $0.1 million from AMMINCO. We expect to continue to pay for these support services in the future.

In December 2018, in accordance with the Company´s tax sharing agreement with its parent, the Company´s Peruvian operations advanced $11 million to AMC for the payment of the Company's GILTI tax that later was determined not to be necessary. This amount was reimbursed to the Company in the first quarter of 2019.

In 2019, our Mexican operations paid $44.1 million primarily for freight services provided by Ferrocarril Mexicano, S.A. de C.V. and was paid $0.1 million by Ferrocarril, $71.0 million for engineering and construction services provided by Mexico Proyectos y Desarrollos, S.A. de C.V. and affiliates, and $202.2 million for power supplied by Mexico Generadora de Energia S. de R.L. (“MGE”), all subsidiaries of Grupo Mexico. In 2019 the Company received from MGE $47.4 million for natural gas and services. On August 4, 2014, Mexico Generadora de Energia Eolica S. de R.L. de C.V, an indirect subsidiary of Grupo Mexico, located in Oaxaca, Mexico, acquired Eolica el Retiro. Eolica el Retiro (“Eolica”) is a windfarm that has 37 wind turbines. This company started operations in January 2014 and started to sell power to Industrial Minera Mexico, S.A. de C.V. and subsidiaries (“IMMSA”) and other subsidiaries of Grupo Mexico in the third quarter of 2014. Eolica is currently supplying approximately 18.2% of its power output to IMMSA, a subsidiary of the Company. Our Mexican operations purchased power from Eolica for $2.9 million in 2019.

In 2012, the Company signed a power purchase agreement with MGE, whereby MGE will supply some of the Company’s Mexican operations with power through 2032. MGE has two natural gas-fired combined cycle power generating units, with a net total capacity of 516.2 megawatts and has been supplying power to us since December 2013. Currently, MGE is supplying approximately 5.2% of its power output to third-party energy users.

In 2019, the Company’s Mexican operations purchased $37.6 million in scrap and other residual copper mineral and sold $11.4 million in copper cathodes and rod, as well as sulfuric acid, silver and gold to Asarco LLC, a subsidiary of Grupo Mexico.

In September 2019, Asarco LLC signed a promissory note to pay to the Company´s Mexican operations $62.0 million plus interest no later than October 31, 2021, with quarterly payments of $0.5 million. The annual interest rate of the note is Libor plus 200 basis points, 4.08513%, which will be reviewed annually. As of December 31, 2019, $59.5 million is recorded as a long-term related party receivable in the consolidated balance sheet of the Company. Related to this promissory note, the Company recorded interest income of $2.3 million in 2019.April 30, 2021.


In 2019, the Company made donations of $9.6 million to Fundacion Grupo Mexico, an organization dedicated to promoting the social and economic development of the communities close to the Company’s Mexican operations.

The Larrea family controls a majority ofinformation contained in such definitive proxy statement is incorporated herein by reference, excluding the capital stock of Grupo Mexico, and has extensive interests in other businesses, including transportation, aviation, entertainment and real estate. We engage in certain transactions ininformation under the ordinary course of business with other entities controlled by the Larrea family relating to the lease of office space, air transportation and entertainment services. In 2019, we paid Mexico Transportes Aereos S.A. de C.V. $2.3 million for aviation services provided to our Mexican operations. The Company’s Mexican operations paid $0.4 million and $0.2 million to Boutique Bowling de Mexico S.A de C.V. and Operadora de Cinemas S.A. de C.V. for entertainment services, respectively. These companies are controlled by the Larrea family. In addition, the Company received $1.8 million, $0.1 million and $0.1 million from Mexico Transportes Aereos S.A. de C.V., Boutique Bowling de Mexico S.A. de C.V., and Operadora de Cinemas S.A. de C.V., respectively, for building rental and maintenance services provided by our Mexican subsidiary. The Company´s Mexican operations also received $0.2 million from Empresarios Industriales de Mexico, S. A. de C. V. for providing security services.

In 2019, we did not have purchase activities with companies having relationships with our executive officers.

The Company has a 44.2% participation in Compañia Minera Coimolache S.A. (“Coimolache”),caption “Compensation Committee Report,” which it accounts for on the equity method. Coimolache owns Tantahuatay, a gold mine located in the northern part of Peru. Messrs. Gonzalez Rocha, Jacob and Corrales are directors of Coimolache.

In addition, the Company has a 30.0% participation in Apu Coropuna S.R.L. (“Apu Coropuna”), which it accounts for on the equity method. Apu Coropuna is a company, which undertakes exploration activities in the Pucay prospect, located in Arequipa, Peru. Mr. Edgard Corrales is a member of the management Committee of Apu Coropuna.

Asarco LLC, a subsidiary of Grupo Mexico, and AMC, the parent of the Company, employ Oscar González Barron, the son of Oscar González Rocha, our Chief Executive Officer. Mr. González Barron holds the position of Chief Financial Officer at Asarco LLC and received $47,856 as his base salary along with other employment benefits that are standard for employees of Asarco LLC at that management level, such as the use of the Company car valued at $4,005. Mr. González Barron did not receive a discretionary cash bonus from Asarco LLC in 2019. Mr. Oscar González Barron holds the office of Corporate Director of Administration and Internal Control at AMC and received a base salary from AMC of $186,900 in 2019. He also received a cash discretionary bonus from AMC of $39,061 in 2019. Mr. González Barron also received fees from Grupo Mexico amounting to $10,383 in 2019. Mr. Oscar González Rocha was not involved in the recruiting or hiring of Mr. Oscar González Barron by Asarco LLC or AMC, nor in any decision affecting Mr. González Barron’s compensation at Asarco LLC or at AMC.  Mr. Oscar González Barron’s compensation was established by Asarco LLC and AMC, respectively, in accordance with their compensation practices applicable to employees with equivalent qualifications and responsibilities and holding similar positions.

It is anticipated that in the future we will enter into similar transactions with such parties.

On February 28, 2017, AMC and the Company entered into a tax agreement (the “Tax Agreement”), effective as of February 20, 2017, pursuant to which AMC, as the parent of the consolidated group of which the Company is a member and joins in the filing of a U.S. federal income tax return, (a) will be responsible for and discharge, any and all liabilities and payments due to the IRS on account of any incremental tax liabilities of the Company in connection with the potential adjustments being considered by the IRS in connection with the interest of a 2012 Judgment, (b) will not seek reimbursement, contribution or collection of any amounts of money or any other asset in connection therewith from the Company, and (c) will indemnify, defend and hold harmless the Company from any such liability, including the cost of such defense.


The Audit Committee reviewed the 2019 related party transactions reported in this report and did not object to any of them. Our Audit Committee recognizes that related party transactions present a heightened risk of conflicts of interest and/or improper valuation (or the perception thereof) and adopted a written policy for related party transactions on January 24, 2007, and amended it on February 23, 2007, and on April 24, 2008.  During 2019 it was our policy that the Audit Committee shall review all related party transactions. Related parties were those defined as such by the SEC. We are required to report all related party transactions in our filings with the SEC and as required by accounting requirements.

Article Nine of our Certificate specifically states: “The Corporation shall not engage in any Material Affiliate Transaction unless it has been the subject of prior review by a committee of the Board of Directors with at least three members, each of whom is an Independent Director (any such committee, an “Affiliate Transactions Committee”). For purposes of this Article Nine, a “Material Affiliate Transaction” shall mean any transaction, business dealing or material financial interest in any transaction, or any series of related transactions, between Grupo México or one of its affiliates (other than the Corporation or any of the Corporation’s subsidiaries), on the one hand, and the Corporation or one of the Corporation’s subsidiaries, on the other hand, that involves consideration of more than $10,000,000 in the aggregate.”

During 2019 our policy provided that the Audit Committee may delegate authority to grant such approvals or ratifications to one or more members of the Audit Committee with the requirement that such member or members present any decisions made pursuant to such delegated authority to the full Audit Committee at its next scheduled meeting.

Additionally, during 2019 the policy provided that in transactions where a senior officer is related to any of our goods or services provider, the Chairman of the Audit Committee is delegated the authority to approve the transaction, unless it exceeds an aggregate consideration of more than $500,000.  In the latter case, prior approval of the Audit Committee members is required.

During 2019 our policy provided that in reviewing a related party transaction the Audit Committee had to consider all of the relevant factors surrounding the transaction, including:

(1)       whether there is a valid business reason for us to enter into the related party transaction consistent with the best interests of the Company and our stockholders;

(2)       whether the transaction is negotiated on an arm’s length basis on terms comparable to those provided to unrelated third parties or on terms comparable to those provided to employees generally;

(3)       whether the Audit Committee determines that it has been duly apprised of all significant conflicts that may exist or may otherwise arise on account of the transaction, and it believes, nonetheless, that we are warranted in entering into the related party transaction and have developed an appropriate plan to manage the potential conflicts of interest;

(4)whether the rates or charges involved in the transaction are determined by competitive bids, or the transaction involves the rendering of services as a common or contract carrier, or public utility, at rates or charges fixed in conformity with law or governmental authority;

(5)       whether the transaction involves services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services; and/or

(6)whether the interest of the related party or that of a member of the immediate family of the related party arises solely from the ownership of our class of equity securities and all holders of that class of our equity securities received the same benefit on a pro rata basis.


During 2019, management reported all related party transactions to the Audit Committee at each meeting, including material transactions that require approval or ratification. On April 25, 2017, the Audit Committee created a subcommittee of related party transactions, composed of three of its members, with the authority to review related party transactions, including material affiliate related party transactions. Material related party transactions are reported to the full Board of Directors. During 2019, our policy provided a presumption that the Audit Committee has approved or ratified the related party transaction if it has reviewed the transaction and made no observations or objections to the same.

During the second half of 2019, at the direction of the Audit Committee and with the input of the subcommittee of related party transactions, management undertook to revise our internal policies and procedures to establish channels of reporting and review and approval requirements for related party transactions. This revised policy was developed to complement our existing practices covering related party transactions, including the Audit Committee’s policy described above. While the revised policy addressed the subject of related party transactions and the potential conflict of interest they present generally, a particular focus of the revised policy is to assist our employee base to identify potential transactions described by Article Nine of our Certificate as early as possible and establish a chain of internal reporting to help ensure that we do not engage in any Material Affiliate Transaction (as defined in Article Nine of our Certificate) unless that transaction has been the subject of prior review by a committee of three independent members of our board of directors. This revised policy was approved by our Board of Directors at its meeting of February 20, 2020.

As an example of the revised policy’s enhanced control functions, related party transactions with consideration between $8,000,000 and $10,000,000 are to be pre-approved by our General Counsel and Chief Financial Officer. If the General Counsel and Chief Financial Officer have any questions about the consideration amount, they may refer a proposed related party transaction to the committee of three independent directors for consideration.

 Director Independence

Messrs. Luis Miguel Palomino Bonilla, Gilberto Perezalonso Cifuentes, and Carlos Ruiz Sacristán are our special independent directors. Messrs.  Vicente Ariztegui Andreve, Enrique Castillo Sánchez Mejorada and Rafael Mac Gregor Anciola are our fourth, fifth and sixth independent directors. At its meeting on February 20, 2020, the Board of Directors approved the nomination of special independent directors made by the Special Nominating Committee and endorsed the determination made by the Special Nominating Committee that Messrs. Luis Miguel Palomino Bonilla, Gilberto Perezalonso Cifuentes, and Carlos Ruiz Sacristán are independent of management in accordance with the requirements of the NYSE, as such requirements are interpreted by the Special Nominating Committee and our Board of Directors in their respective business judgments. The Board of Directors also determined that Messrs.  Vicente Ariztegui Andreve, Enrique Castillo Sánchez Mejorada and Rafael Mac Gregor Anciola are independent of management in accordance with the requirements of the NYSE as such requirements are interpreted by our Board of Directors in its business judgment.

Audit Committee Pre-Approval Policies and Procedures

Our management defines and communicates specific projects and categories of service for which the advance approval of the Audit Committee is requested. The Audit Committee reviews these requests and advises management if it approves the engagement of the independent accountants. On July 19, 2010, the Audit Committee decided that management could engage the services of the independent accountants for special projects in amounts up to $30,000, provided they would be approved at the next scheduled Audit Committee meeting. Management could only engage the services of the independent accountants for up to two special projects each calendar year, not exceeding $60,000. For services between $30,000 and $60,000, the services would have to be approved by the Chairman of the Audit Committee and would have to be reported to the full Audit Committee at the next scheduled Audit Committee meeting.  For services in excess of $60,000, the full approval of the entire Audit Committee would be required previous to the engagement. In 2019, all services provided by DTT were approved in advance by the Audit Committee.
