PART I.

ITEM 1. BUSINESS

THE COMPANY

Southern Copper Corporation (“SCC”, “Southern Copper” or the “Company”) is one of the largest integrated copper producers in the world. We produce 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. Our operations make 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 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. Our precious metals plant at the Ilo refinery produces refined silver and gold, as well as other materials. Additionally, we produce refined copper using SX-EW technology. We operate the Toquepala and Cuajone 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 which produces refined silver and 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 at the site of one of the world’s largest copper ore deposits, a copper concentrator and two 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, a coal mine and a zinc refinery.

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

The sales prices for our products are largely determined by market forces outside of 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 to remain profitable during periods of low copper prices and on 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 “nuevo sol”, “nuevos soles” or “S/.”, are to Peruvian nuevos soles; and references to “peso”, “pesos”, or “Ps.”, are to Mexican pesos.

Unit Information:

Unless otherwise noted, all tonnages are in metric tons. To convert to short tons, multiply by 1.102. All ounces are troy ounces. All distances are in kilometers. To convert to miles, multiply by 0.621. To convert hectares to acres, multiply by 2.47.

ORGANIZATIONAL STRUCTURE

The following chart describes our organizational structure, starting with our controlling stockholders, as of December 31, 2014. For clarity of presentation, the chart identifies only our main subsidiaries and eliminates intermediate holding companies.

We are a majority-owned, indirect subsidiary of Grupo Mexico S.A.B. de C.V. (“Grupo Mexico”). At December 31, 2014, Grupo Mexico through its wholly-owned subsidiary Americas Mining Corporation (“AMC”) owned 84.6% of our capital stock. Grupo Mexico’s principal business is to act as a holding company for shares of other corporations engaged in the mining, processing, purchase and sale of minerals and other products and 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 substantially all of our assets and liabilities associated with our copper operations in Peru. The SPCC Peru Branch is not a corporation separate from us and, therefore, obligations of SPCC Peru Branch are direct obligations of SCC and vice-versa. It is, however, an establishment, registered pursuant to Peruvian law, through which we hold assets, incur liabilities and conduct operations in Peru. Although it has neither its own capital nor liability separate from us, it is deemed to have equity capital for purposes of determining the economic interests of holders of our investment shares (See Note 12 “Non-Controlling Interest” of our consolidated financial statements).

On April 1, 2005, we acquired Minera Mexico, the largest mining company in Mexico on a stand-alone basis, 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, 2014 we have purchased 79.9 million shares of our common stock at a cost of $1,842.3 million. 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.

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 the world’s third most widely used metal, after iron and aluminum, and an important component in the world’s infrastructure. Copper has unique chemical and physical properties, including high ductility, malleability, and thermal and electrical conductivity, and resistance to corrosion that has made it a superior material for use in electrical and electronic products, including power transmission and generation, which accounts for about three quarters of its global copper use, 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, in many industrial and consumer applications.

Copper is an internationally traded commodity with prices principally determined by the major metal exchanges, the Commodities Exchange, or “COMEX”, in New York and the London Metal Exchange or “LME.” Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage 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 increasing share of copper is produced from acid leaching of oxidized ores. Copper is one of the oldest metals ever used and has been one of the most important materials in the development of civilization.

BUSINESS REPORTING SEGMENTS:

Our management views Southern Copper as having three reportable segments and manages it on the basis of these segments.

The three segments identified are groups of individual mines, each of which constitutes an operating segment with similar economic characteristics, type of products, 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.  Added to the segment information 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. Sales of its products are recorded as revenue of our Peruvian mines. The Peruvian operations produce copper, with production of by-products of molybdenum, silver and other material.

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 material.

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

Financial information is regularly prepared for each of the three segments and the results are reported to Senior Management on a segment basis. Senior Management 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 our consolidated financial statements.

CAPITAL INVESTMENT PROGRAM AND EXPLORATION ACTIVITIES

For a description of our capital investment program, see Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Capital Investment Program” and for our exploration activities, see Item 2 “Properties — Explorations Activities.”

PRINCIPAL PRODUCTS AND MARKETS

Copper is primarily used in the building and construction industries, electrical and electronic products and, to a lesser extent, 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, 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, in the manufacturing of batteries and in the form of sheets for architectural purposes.

Our marketing strategy and annual sales planning emphasize developing and maintaining long-term customer relationships. Thus 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 prevailing commodity prices for the quotation period according to the terms of the contract.

We focus on the ultimate end-user customers as opposed to selling on the spot market or to trading companies. In addition, we devote significant marketing effort to diversifying our sales both by region and by customer base. We also strive to provide superior customer service, including timely deliveries of our products. Our ability to consistently fulfill customer demand is supported 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 our 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, the two most important metal exchanges in the world. 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.”

The table below shows the high, low and average COMEX and LME per pound copper prices during the last 10 years:

COMPETITIVE CONDITIONS

Competition in the copper market is based primarily on price and service basis, with price being the most important consideration 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.”

LABOR FORCE

As of December 31, 2014, we had 12,735 employees, approximately 71% of whom are unionized and represented by 10 different labor unions. In recent years we have experienced a positive labor environment in our operations in Mexico and Peru, which is allowing us to increase productivity as well as helping us achieve the goals of our capital expansion program.

Peru

Approximately 69% of our 4,524 Peruvian employees were unionized at December 31, 2014. There are seven separate unions, three of them at each major production area that represent the majority of our workers; and four smaller unions that represent the balance of workers. Our collective bargaining agreements with all of these unions will expire in the second half of 2015. We expect to begin negotiations for new agreements in the second quarter of 2015.

Employees of the Toquepala and Cuajone units reside in townsites, where we have built 3,700 houses and apartments. We also have 90 houses at 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

Approximately 73% of our 8,105 Mexican employees were unionized at December 31, 2014, represented by three separate unions. Under Mexican law, the terms of employment for unionized workers is set forth in collective bargaining agreements. Mexican companies negotiate the salary provisions of collective bargaining agreements with the labor unions annually and negotiate other benefits every two years. We conduct negotiations separately at each mining complex and each processing plant.

In recent years, the Mexican operations have experienced a positive improvement of their labor environment as our workers opted to change their affiliation from the Sindicato Nacional de Trabajadores Mineros, Metalurgicos y Similares de la Republica Mexicana (the National Union of Mine and Metal Workers and Similar Activities of the Mexican Republic or the “National Mining Union”), which was formerly led by Napoleon Gomez Urrutia, to other less politicized unions. We believe that this change has created a more positive labor environment, which will benefit both the Company and workers and allow us to increase our productivity and develop our capital expansion programs.

Our Taxco and San Martin mines in Mexico have been on strike since July 2007. For a discussion of labor matters reference is made 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 2,000 houses and apartments and 275 houses and apartments, respectively. Most of the employees of the IMMSA unit reside on the grounds of the mining or processing complexes in which they work and where we have built approximately 900 houses and apartments. Housing, together with maintenance and utility services, is provided at minimal cost to most of our employees. Our town sites and housing complexes include educational and, in some units, medical facilities, churches, social clubs, shopping centers, banking and other services. Through 2007, the Buenavista unit provided health care services free of charge to employees and retired unionized employees and their families through its own hospital at the Buenavista unit. 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 del Cobre will receive health services from 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 fuels, electricity and water. We use natural gas to power boilers and generators and for metallurgical processes at our Mexican operations and diesel fuel for mining equipment. We believe that sources of fuel, electricity and water are readily available. Although the prices of these raw materials may fluctuate beyond our control, we focus our efforts to reduce these costs through cost and energy saving measures.

Energy is the principal cost in mining, therefore the concern for its conservation and efficient usage is very important. We have energy management committees at most of our mines. The committees meet periodically to discuss consumption and to develop measures directed at saving energy. Also, alternative sources are being analyzed at the corporate level, from both traditional and renewable energy sources. This has helped us to develop a culture of energy conservation directed at the sustainability of our operations.

Peru

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

Electricity: We currently receive power from Enersur S.A. under a power purchase agreement through April 2017. In June 2014, we entered into a power purchase agreement for 120 megawatt (“MW”) with the state company Electroperu S.A., which will supply energy for our Peruvian operations for twenty years starting on April 17, 2017 and ending on April 30, 2037. In July 2014, we entered into a power purchase agreement for 120MW with a private power generator Kallpa, which will supply energy for our Peruvian operations for ten years starting on April 17, 2017 and ending on April 30, 2027. In addition, 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 interconnected with 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 also surface water rights from the Suches lake and two small water courses, Quebrada Honda and Quebrada Tacalaya. We believe these water sources are sufficient to supply the needs of our operating units at Toquepala and Cuajone. At Ilo, we have desalinization plants that produce water for industrial and domestic use that we believe are sufficient for our current and projected needs.

Mexico

Fuel: In Mexico, fuel is purchased directly from Petroleos Mexicanos, (“PEMEX”), the state oil monopoly.

The La Caridad unit imports natural gas from the United States through its pipeline (between Douglas, Arizona and Nacozari, Sonora).  This permits us to import natural gas from the United States 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 fixed price or daily fixed prices for our natural gas purchases.

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

Electricity: Electricity is used as the main energy source at our mining complexes. We 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 are dependent upon the pricing policies of CFE, as well as PEMEX, which reflect government policy, as well as international market prices for crude oil, natural gas and conditions in the refinery markets.

Mexico Generadora de Energia S. de R. L., (“MGE”), a subsidiary of Grupo Mexico, has completed the construction of the two power plants designed to supply power to some of the Company’s Mexican operations. It is expected that MGE will supply approximately 12% of its power output to third party energy users. These plants are natural gas-fired combined cycle power

9

generating units, with a net total capacity of 516.2 megawatts. In 2012, we entered into a power supply agreement with MGE through 2032. The first plant was completed in June 2013 and the second in the second quarter of 2014. MGE already has the authorization for the interconnection with the Mexican electrical system to start operations at the second plant. The first plant began to supply power to the Company in December 2013, and the second plant is ready to supply once the demand in the mine requires it.

Water: In Mexico, water is deemed a public property and industries not connected to a public service water supply must obtain a water concession from Comision Nacional del Agua (the National Water Commission or “CNA”). Water usage fees are established in the Ley Federal de Derechos (the Federal Law of Rights), 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 in each plant in order to conserve and recycle water. Water usage fees are updated on a yearly basis and have been increasing in recent years. In December 2013, federal law pertaining to water rights was amended to change the method used to determine water usage fees for underground and surface water effective January 1, 2014. In 2014, the increase in usage fees had an after tax cost of $20.8 million.

ENVIRONMENTAL MATTERS

For a discussion of environmental matters reference is made to the information contained under the caption “Environmental matters” in Note 13 “Commitments and Contingencies” of the consolidated financial statements.

MINING RIGHTS AND CONCESSIONS

Peru

We have 166,696 hectares in concessions from the Peruvian government for our exploration, exploitation, extraction and production operations, at various sites, as follows:

	Toquepala	Cuajone	Ilo	Other	Total
	(hectares)
Plants	300	456	421	—	1,177
Operations	22,653	23,155	4,607	33,859	84,274
Exploration	—	—	—	81,245	81,245
Total	22,953	23,611	5,028	115,104	166,696

We believe that our Peruvian concessions are in full force and in effect under applicable Peruvian laws and that we are in compliance with all material terms and requirements applicable to these 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 2014, 2013 and 2012, were approximately $1.2 million, $1.2 million and $1.3 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 mining royalty charge is based on operating income margins with graduated rates ranging from 1% to 12% of operating profits, with a minimum royalty charge assessed at 1% of net sales. If the operating income margin is 10% or less, the royalty charge is 1% and for each 5% increment in the operating income margin, the royalty charge rate increases by 0.75%, up to a maximum of 12%. In 2014, 2013 and 2012, we made provisions of $32.4 million, $34.8 million and $51.0 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 approximately 547,815 hectares in concessions from the Mexican government for our exploration and

10

exploitation activities as outlined on the table below.

	IMMSA	La Caridad	Buenavista	Projects	Total
	(hectares)
Mine concessions	185,018	104,854	93,706	164,237	547,815

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 $0.4 to $9.7 per hectare depending on the beginning date of the mining concession. Fees paid during 2014, 2013 and 2012 were approximately $5.7 million, $5.6 million and $4.5 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 constructed.

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 adjusted as defined by Mexican tax regulations and an additional royalty of 0.5% over gross income from sales of gold, silver and platinum. These charges are 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.

The table below provides the sales value of our products as a percentage of our total net sales value.

	Year Ended December 31,
Product	2014		2013		2012
Copper	78.0	%	78.2	%	77.0	%
Molybdenum	8.8	%	6.5	%	6.8	%
Silver	4.7	%	6.6	%	7.4	%
Zinc	3.6	%	3.4	%	2.9	%
Other by-products	4.9	%	5.3	%	5.9	%

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

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

Our business requires levels of capital expenditures which 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 expenditures. We must continue to invest capital to maintain or to 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 levels to generate sufficient cash, or that we 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 do not comply with these obligations, we could be in default under the applicable agreements which, if not addressed or waived, could require repayment of the indebtedness immediately. 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 incurrence of additional debt and liens, on our ability to dispose of assets, or on our ability to pay dividends to our common stockholders.

We may not continue to 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 our results of operations, financial condition, cash requirements, tax considerations, future prospects, legal restrictions,

12

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. In light of our capital investment program and global economic conditions, it is possible that future dividend distributions will be reduced from the levels of recent years.

Operational risks

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

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 increase 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. 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 and damage to equipment. We maintain insurance against many of these and other risks, which in 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 have considered future regulations regarding environmental damage insurance. In case such regulations come into force, we will have to analyze the need to obtain such insurance. We do not have, and do not intend to obtain, political risk insurance. These or other uninsured events may adversely affect our financial condition and the results of operations.

Changes in the level of demand for our products could adversely affect our product sales.

Our revenue is dependent on the level of industrial and consumer demand for the refined, semi-refined metal products and concentrates we sell. Changes in technology, industrial processes and consumer habits may affect the level of demand to the extent that changes increase or decrease the need for our metal products. A change in demand, including any change resulting from economic slow-downs or recessions, could impact our results of operations and financial condition.

Deliveries under our copper sales agreements can be suspended or cancelled by our customers in certain cases.

Under our sales agreements, we or our customers may suspend or cancel delivery of copper during a period of force majeure. Events of force majeure under these agreements include acts of nature, labor strikes, fires, floods, wars, transportation delays, government actions or other events that are beyond the control of the parties. Any suspension or cancellation by our customers of deliveries under our sales contracts that are not replaced by deliveries under new contracts or sales on the spot market would reduce our cash flow and could adversely affect our financial condition and results of operations.

13

Interruptions of energy supply or increases in energy costs and other production costs may adversely affect our results of operations.

We require substantial amounts of fuel oil, electricity and other resources for our operations. Fuel, gas and power costs constituted approximately 34.6%, 34.7% and 34.7% of our total production cost in 2014, 2013 and 2012, respectively. We rely upon third parties for our supply of the energy resources consumed in our operations. The 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, worldwide price levels and market conditions. Disruptions in energy supply or increases in costs of energy resources or increases of other production costs could have a material adverse effect on our financial condition and results of operations.

Shortages of water supply, critical parts, equipment and skilled labor may adversely affect our operations and development projects.

Our mining operations require significant quantities of water for mining, ore processing and related support facilities. 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 of water to which we have rights could require us to curtail or shut down mining production and could prevent us from pursuing expansion opportunities. Additionally, we have not yet secured adequate water rights to support all of our announced expansion projects, and our inability to secure those rights could prevent us from pursuing some of those 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 which 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 work place conditions, including high risk labor and the handling, storage and disposal of chemical and other hazardous substances. We believe our operations are in compliance 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 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 efforts are focused on the health and safety of our workforce in order to continuously improve performance and compliance through implementing occupational health programs, providing adequate training and safety incentive in our operations. 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 2014, 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). Unfortunately, in 2014, we had five fatalities in Mexico, all Company employees; and three fatalities in Peru, one Company employee and two contractor employees. In 2013, we did not have fatalities in Peru or in Mexico. The amounts paid to the Mexican and Peruvian authorities for reportable accidents did not have an adverse effect 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. Also, violation of security and safety laws and regulations in our Peruvian operations can be considered a crime, with 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, involves many risks and is frequently unsuccessful. Once mineralization is discovered, it may take a number of years from the initial phases of drilling before production is possible, during which time the economic feasibility of production may change. Substantial expenditures are required to establish proven and probable ore reserves through drilling, to determine metallurgical processes 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 the expansion or replacement of current production with new proven and probable ore reserves.

14

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 feasibility studies that derive 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. Further, 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 have taken 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 failure or additional requirements to prevent slope failure may negatively affect our results of operations and financial condition, as well as have the effect of diminishing 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, 2014, unions represented approximately 71% of our workforce. Currently, we have labor agreements in effect for our Mexican and Peruvian operations.

Our Taxco and San Martin mines in Mexico have been on strike since July 2007. It is expected that operations at these mines will remain suspended until these labor issues are resolved.

We cannot assure you when these strikes 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 mine and Toquepala expansion projects in Peru have experienced delays while trying to resolve differences with community groups.

It appears that it is becoming a part of the Peruvian mining environment that in order to obtain acceptance from local communities for projects in their localities, demands for substantial investments in community infrastructure and upgrades must be met in order to proceed with the mining projects.

We are confident that we will continue with the Tia Maria mine and the Toquepala expansion projects. However, we cannot assure you that we will not continue to incur additional costs for community infrastructure and upgrades in order to obtain the approval of current or future mining projects.

Environmental, regulatory response to 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, as well as 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 been required to dedicate more time and money to compliance and remediation activities. Furthermore, Mexican authorities have

15

become more rigorous and strict in enforcing Mexican environmental laws. We expect additional laws and regulations will be enacted over time with respect to environmental matters.

The principal legislation applicable to our 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. Article 180 of this law was amended in 2011. This amendment eases the ability for an individual or entity to contest administrative acts, including environmental authorizations, permits or concessions. As a result, more legal actions supported or sponsored by non-governmental groups interested in halting projects, and not necessarily in protecting the rights of affected communities, may be filed against us. Additionally, amendments to the Civil Federal Procedures Code and the enforcement of the Environmental Liability Federal Law may result in more litigation, including suspension of the activities alleged to cause harm and/or economic fines.

The Company is subject to Peruvian environmental laws imposing closure and remediation obligations on the mining industry. Under the closure regulations, mines must submit a closure plan that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and post-closure plans and financial assurance. Both, estimated costs and remediation work may increase or decrease significantly in the future as a result of changes in closure laws and regulations, changes in engineering designs and technology, permit modifications or updates, changes in mine plans, inflation or other factors as actual reclamation spending occurs and could materially impact the amounts charged to operations for reclamation and remediation.

In addition, in 2012 we decided to recognize an estimated asset retirement obligation for our mining properties in Mexico as part of our environmental commitment, even though, there is currently no enacted law, statute, ordinance, or written or oral contract requiring us to carry out mine closure and environmental remediation activities. Moreover, our Mexican operations are also subject to the environmental agreement entered into by Mexico, the United States and Canada in connection with the North American Free Trade Agreement. This agreement, as well as new international treaties regarding human rights, contains environmental provisions and initiatives. We believe our operations are in material compliance with all environmental laws and regulations within the areas we operate.

Regulatory response to climate change, restrictions, caps, taxes, or other controls on emissions of greenhouse gasses, including on emissions from the combustion of carbon-based fuels, could significantly increase our operating costs. Restrictions on emissions could also affect our customers. A number of governments or governmental bodies have introduced or are contemplating regulatory changes in response to the potential impacts of climate change. These regulatory initiatives will be either voluntary or mandatory and may impact our operations directly or through our suppliers or customers.

Our Peruvian operations are affected by environmental regulations which establish stringent air quality standards. The Peruvian environmental agency has designated three atmospheric basins that require further attention to comply with these air quality standards. The Ilo basin is one of these three areas. We expect to join the local government and other stakeholders in the Ilo basin to develop the action plan and evaluate alternatives and their feasibility in order to achieve these new air quality standards.

Additionally, in 2013, the Peruvian government enacted a new soil environmental quality standard applicable to any existing facility or project that generates or could generate risk of soil contamination in its area of operation or influence. The rule applies to new projects as well as existing operations and requires soil testing analysis. We are currently working with a consultant to carry out soil sampling, studies and other tests to comply with the requirements of the rules.

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

The development of more stringent environmental protection programs in Peru and Mexico and in relevant trade agreements could impose constraints and additional costs on our operations requiring us to make significant capital expenditures in the future. We cannot assure you that current or future legislative, regulatory or trade developments will not have an adverse effect on our business, properties, operating results, financial condition or prospects.

16

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

Our Company is in the midst of a large expansion program, which may subject us to additional risks 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 the increased activity occurring at our sites could cause accidents of an environmental nature or danger to human life.

In August 2014, our new SX-EW plant in Mexico had an industrial accident caused by a rock slide, coupled with a construction defect in the seal of a pipe at the new leaching system containment dam, which caused a spill of copper sulfate solution in to the Bacanuchi River, a tributary of the Sonora River.  As a result of this accident the Company absorbed a charge of $91 million in its 2014 results.  While this is an unusual event in the Company’s history, we cannot offer assurance that  an accident related to our project development program will not occur again in the future and cause environmental damage or damage that causes harm or loss of life.

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

Our operations depend upon information technology systems which 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 believe that we have implemented appropriate preventative measures to mitigate potential risks by implementing a certified IT service management system with the necessary controls that are frequently reviewed and tested, including a risk matrix that considers all the possible threats with an impact and probability analysis, actions to avoid or mitigate them and the corresponding testing plan. 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, the compromising of confidential or otherwise protected information, destruction or corruption of data, security breaches, financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, competitive position, financial condition or results of 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 the 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.

Our management has identified a material weakness in our internal control over financial reporting, which could, if not remediated, result in material misstatements in our future financial statements and may adversely affect our business and stock price.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). As disclosed in Item 9A “Controls and Procedures,” our management identified a material weakness in our internal control over financial reporting related to ineffective design of processes and procedures to restrict access to key financial systems and records to appropriate users.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement in our annual or interim financial statements will not be prevented or detected on a timely basis. As a result of the material weakness discussed above, our management concluded that our internal control over financial reporting was not effective as of December 31, 2014. We cannot assure you that additional material weaknesses in our internal control over financial reporting will not be identified in the future. Although we are implementing remedial measures designed to address the identified material weakness, if our remedial measures are insufficient to address the material weakness, or if additional material weaknesses or significant deficiencies in our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may contain material misstatements. These misstatements could result in additional restatements of our consolidated financial statements, cause us to fail to meet our reporting obligations, which could result in a default under our debt instruments, reduce our ability to obtain financing, increase the cost of any financing that we obtain or cause investors to lose confidence in our reported financial information, which could lead to a decline in our stock price.

Although we are working to remedy the ineffectiveness of our internal control over financial reporting, there can be no assurance as to when the remediation plan will be fully implemented or the aggregate cost of implementation. Until our remediation plan is fully implemented and considered complete, our management will continue to devote significant time and attention to these efforts. If we do not complete our remediation in a timely fashion, or at all, or if our remediation plan is inadequate, there will continue to be an increased risk that we will be unable to timely file future periodic reports with the SEC and that our future consolidated financial statements could contain errors that will be undetected. For more information relating to our internal control over financial reporting (and disclosure controls and procedures) and the remediation plan undertaken by us, see Item 9A “Controls and Procedures.”

17

The copper mining industry is highly competitive.

We face competition from other copper mining and producing companies around the world. We cannot assure you that competition will not adversely affect us in the future.

In addition, mines have limited lives and, as a result, we must periodically seek to replace and expand our reserves by acquiring new properties. Significant competition exists to acquire properties producing or capable of producing copper and other metals.

The mining industry has experienced significant consolidation in recent years, including consolidation among some of our main competitors, as a result an increased percentage of copper production is from companies that also produce other products and may, consequently, be more diversified than we are. We cannot assure you that the result of current or future consolidation in the industry will not adversely affect us.

Potential changes to international trade agreements, trade concessions or other political and economic arrangements may benefit copper producers operating in countries other than Peru and Mexico, where our mining operations are currently located. We cannot assure you that we will be able to compete on the basis of price or other factors with companies that may benefit from future favorable trading or other arrangements.

Our results and financial condition are affected by global and local market conditions.

We are subject to the risks arising from adverse changes in domestic and global economic and political conditions. Our industry is cyclical by nature and fluctuates with economic cycles.

Weakness in the global economy can be marked by, among other adverse factors, lower levels of consumer and corporate confidence, decreased business investment, lower consumer spending, increased unemployment, reduced income and asset values in many areas, currency volatility and limited availability of credit and access to capital.

Concerns over weaknesses in the global economy may prompt our customers to slow down or reduce the purchase of our products. We may experience longer sales cycles, difficulty in collecting sales proceeds, and lower prices for our products. A change in the demand of our products could impact our results of operations and financial condition. We cannot provide any assurance that any of these events will not have a material adverse effect on market conditions, prices of our securities, our ability to obtain financing, and our results of operations and financial condition.

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, 2014, Grupo Mexico owned indirectly 84.6% of our capital stock. Certain of our and Minera Mexico’s officers and directors 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 our minority stockholders.

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;

18

·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 increased financial obligations of Grupo Mexico or AMC resulting from financings or for other reasons will not result in our parent corporations obtaining loans, increased dividends or other funding from us.

In addition, we have in the past engaged in, and expect to continue to engage in, transactions with Grupo Mexico and its other affiliates which 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.”

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 decided adversely to 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”.

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

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 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 part of our operations are 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. During the past several decades, Peru has had a succession of regimes with differing policies and programs. Past governments have frequently intervened in the nation’s economy and social structure. Among other actions, past

19

governments have imposed controls on prices, exchange rates and local and foreign investments, as well as limitations on imports, have restricted the ability of companies to dismiss employees and have prohibited the remittance of profits to foreign investors.

In more recent years Peru has had political and social stability. The Peruvian government’s economic policies reduced inflation and the Peruvian economy has experienced significant growth. On October 2014 Peru held regional and mayor elections and, in 2016, will hold a new presidential election. Peruvian law prohibits the immediate reelection of the current president.

Because we have significant operations in Peru, we cannot provide any assurance that political developments and economic conditions in Peru and/or other factors will not have a material adverse effect on market conditions, prices of our securities, our ability to obtain financing and our results of operations and 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. In the last quarter of 2014, the international economy was affected by a general appreciation of the U.S. dollar that was caused by the difference between the growth rhythm and the expectations on the monetary position of the United States regarding the main advanced economies and the majority of emerging economies. Accordingly, the Bank of Mexico expects higher growth in 2015 due to the dynamism of the U.S. economy. Gross domestic product grew by 2.1% and 1.3% in 2014 and 2013, respectively, and the Bank of Mexico expects a growth between 2.5% and 3.5% in 2015. Other risks in Mexico are increases in taxes on the mining sector and higher royalties as was 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, security institutions in Mexico are under significant stress, as a result of drug-related violence. This situation creates potential risks especially for transportation of minerals and finished products, which affect a small part of our production. However, drug-related violence has had a limited impact on our operations as it has tended to concentrate outside our areas of production. If this were to change, the potential risks to our operations might increase.

Because we have significant operations in Mexico, we cannot provide any assurance that political developments and economic conditions as well as drug-related violence, in Mexico will not have a material adverse effect on market conditions, prices of our securities, on our ability to obtain financing and on our results of operations and financial condition.

Peruvian inflation and fluctuations in the nuevo 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 due to the countries we operate, portions of our operating costs are denominated in Peruvian nuevos soles. Accordingly, when inflation or deflation in Peru is not offset by a change in the exchange rate of the Nuevo sol, our financial position, results of operations, cash flows and the market price of our common stock could be affected.

Over the past several years, Peru has experienced one of its best economic periods. Inflation in 2014, 2013 and 2012 was 3.2%, 2.9% and 2.6%, respectively. The value of the nuevo sol has devalued against the U.S. dollar 6.9% in 2014, devaluated against the U.S. dollar 9.6% in 2013 and appreciated against the U.S. dollar, 5.4% in 2012. 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 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

20

net income generated by our Mexican operations is adversely affected. The annual inflation rate in Mexico was 4.1% in 2014, 4.0% in 2013 and 3.6% in 2012. The Bank of Mexico has publicly announced a target of 3% inflation for 2015.

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 to the U.S. dollar decreased by 12.6% in 2014, decreased by 0.5% in 2013 and increased by 6.9% in 2012.

The Mexican government does not currently 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 restriction 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.

Developments in other emerging market countries and in the United States may adversely affect the prices of our common stock and our debt securities.

The market value of securities of companies with significant operations in Peru and Mexico is, to varying degrees, affected by economic and market conditions in other emerging market countries. Although economic conditions in such countries may differ significantly from economic conditions in Peru or Mexico, as the case may be, investors’ reactions to developments in any of these other countries may have an adverse effect on the market value or trading price of the securities, including debt securities, of issuers that have significant operations in Peru or Mexico.

In addition, in recent years economic conditions in Mexico have increasingly become correlated to U.S. economic conditions. Therefore, adverse economic conditions in the United States could also have a significant adverse effect on Mexican economic conditions, including the price of our common stock or debt securities.

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 in emerging market countries.

REVIEW OF OPERATIONS

The following maps set forth 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, as well as a coal mine and a coke oven.

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.

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.

22

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 dosified in a casting machine.  The dosified 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.

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.

23

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 Peruvian processing facilities to produce sulfuric acid, some of which is, in turn, used for the copper leaching process, with the rest sold to mining and fertilizer companies located principally in Mexico, Peru, United States, Chile and other countries.

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 approximately 825 meters and 930 meters deep, respectively. Under the present mine plan configuration the Toquepala pit will reach a depth of 1,635 meters and the Cuajone pit will reach a depth of 1,290 meters. The deepening pits present us with a number of geotechnical challenges. Perhaps the foremost concern is the possibility of slope failure, a possibility that all open-pit mines face. In order to maintain slope stability, in the past 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 in Vancouver, B.C. with a group of recognized slope stability and open-pit mining specialists. The agenda for these meetings was principally a review of pit design for mines with greater than 700 meter depth. The discussions included practices for monitoring, data collection and blasting processes.

Based on the concepts defined at the Vancouver meetings, we initiated slope stability studies to define the mining of reserves by optimum design. These studies were performed by outside consultants and included slope stability appraisals, evaluation of the numerical modeling, slope performance and inter-ramp angle design and evaluation of hydrological conditions.

The studies were completed in 2000 and we believe we implemented the study recommendations. One of the major changes implemented was slope angle reduction at both mines, Toquepala by an average of five degrees and Cuajone by an average of seven degrees. Although this increased the waste included in the mineable reserve calculation, it also improved the stability of the pits.

In the Toquepala mine in 2007 we installed 20 meter wide geotechnical berms every 10 benches. We believe this will further strengthen the stability of the Toquepala pit.

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, implementing vibration monitoring and blasting designs of low punctual energy and pre-split techniques. Also a new slope monitoring system was implemented using reflection prisms, deformation inclinometers and piezometers for water level control, as well as real-time robotic monitoring equipment. 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 program of oriented geotechnical drilling, totaling 20,000 meters, was executed at the Toquepala mine. This program, which began in May 2013, is part of the slope stability upgrade study and it is being executed by the team of mining consultants, including Itasca S.A., Stacey Mining Geotechnical Ltd. and Piteau Associates. During the execution of this program additional instrumentation has been implemented, including eight vibrating wire piezometers. The study report includes slope stability appraisals, evaluation of the numerical modeling, slope performance and inter-ramp angle design and evaluation of hydrogeological conditions. Additionally, in 2013, at the Toquepala mine, 366.15 meters of geotechnical drilling was carried out to install 3 inclinometers in the instability zone of the west ramp. In 2014, as part of the slope stability upgrade study, the consultants completed the final report for phase 1A of this study, the preliminary structural domains and updated major structure models.

In 2013, a mining consulting group began a study of dump stability at the Toquepala mine. This study will include an assessment of the current stability of the dumps and will develop a geotechnical campaign to obtain information to assess the stability of the future and final stages of the dumps.

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, followed in August 2013 with the second radar installation and a geotechnical surveillance camera was added. This new system improves the reliability and continuity of monitoring, improves the quality of information used to evaluate the performance of the slopes and

30

helps 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). Also during 2013, we drilled 772 meters of sub-horizontal holes in order to drain the east slope of the pit. The geotechnical study for the new 15 years mine development plan, is being prepared by SRK Consulting Chile and is expected to be completed in early 2015; this study will contain recommendations for improving the stability of the pit slopes.

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

To increase the possibility of mining in the event of a slide, we have provided for two ramps of extraction 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. Likewise, 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 the mine plan for La Caridad mine prepared in 2010. This mine plan replaced the 15-year mine plan prepared in 2004. However, since final pit limits have not been yet 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. We continue to collect new information related to geotechnical data and other geology features in order to ensure the structural security and also to improve the geotechnical data base for future studies.

At the Buenavista mine, we are following the recommendations of a geotechnical evaluation of design slope for the 15-year pit plan. This evaluation was prepared by an independent mine consulting firm. This evaluation 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 that resulted 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 relative 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 implementations.

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

31

continued during 2012 with a drilling program of 3,797 meters in several monitoring wells in order to allow us to continue with the current mining plan.

In 2013, Buenavista continued the drilling program monitoring the extraction wells in the area of Increment (Phase) 5 of the mine and beyond the current limits of the open pit mine.

During 2013, the program to dewater the Buenavista pit bottom was continued in accordance with the short and medium term mine plans. Pumping from sumps located in Increment 5, 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 thus 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 the filtration and seepage through fractures.

A total of 7,339 meters were drilled during 2013 for 30 extraction wells, three of these wells are located in the area of Increment (Phase) 5. 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 was prepared to increment the geotechnical data base. Following the recommendations of geotechnical evaluation we continue monitoring the walls using the radar system.

For 2015 we will increment the geophysical information to analyze and determine the principal filtration structures, for better locations of water extraction wells. With a diamond drilling program of 19,000 meters we will supplement our geotechnical information.

Various studies are now being conducted by outside specialized consultants in order to establish long-range mine water management objectives and to implement recommendations for the efficient use of this resource.

Geology

The Cuajone porphyry copper deposit is located on the western slopes of Cordillera Occidental, in the southern-most Andes Mountains 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 28 kilometers from the Toquepala deposit and is part of the Toquepala Group dated 60 to 100 million years (Upper Cretaceous to Lower Tertiary).  The Cuajone lithology includes volcanic rocks from Cretaceous to Quaternary.  There are 32 rock types including, pre-mineral rocks, basaltic andesite, porphyritic rhyolite, Toquepala dolerite and intrusive rocks, including diorite, porphyritic latite, breccias and dikes.  In addition, the following post-mineral rocks are present; the Huaylillas formation which appears in the south-southeast side of the deposit and has been formed by conglomerates, tuffs, traquites and agglomerates.  These formations date 17 to 23 million years and are found in the Toquepala Group as discordance.  The Chuntacala formation which dates 9 to 14 million years and is formed by conglomerates, flows, tuffs and agglomerates placed gradually in some cases and in discordance in others.  Also Quaternary deposits are found in the rivers, creeks and hills.  The mineralogy is simple with regular grade distribution and vertically funnel-shaped.  Ore minerals include chalcopyrite (CuFeS2), chalcosine (Cu2S) and molybdenite (MoS2) with occasional galena, tetraedrite and enargite as non-economic material.

Concentrator

Our Cuajone operations use state-of-the-art computer monitoring systems at the concentrator, the crushing plant and the flotation circuit in order to coordinate inflows and optimize operations.  Material with a copper grade over 0.35% is loaded onto rail cars 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, but separating waste material called tailings.  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 where water is recovered. The remaining tailings are sent to the Quebrada Honda dam, our principal tailings storage facility.

Toquepala

Our Toquepala operations consist of an open-pit copper mine and a concentrator.  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.  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).  The 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 concentrator.

Geology

The Toquepala porphyry copper deposit is located on the western slopes of Cordillera Occidental, in the southern-most Andes Mountains of Peru.  The deposit is part of a mineral district that contains two additional known deposits, Cuajone and Quellaveco.

The Toquepala deposit is in the southern region of Peru, located on the western slope of the Andes mountain range, 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 in a territory with intrusive and eruptive activities of rhyolitic and andesitic rocks which are 70 million years old (Cretaceous-Tertiary) and which created a series of 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 which broke and smelted the rocks of the Toquepala Group.  These intrusive activities resulted in diorites, granodiorites and dikes of porphyric dacite.  Toquepala has a simple mineralogy with regular copper grade distribution.  Economic ore is found as disseminated sulfurs throughout the deposit as veinlets, replenishing empty places or as small aggregates.  Ore minerals include chalcopyrite (CuFeS2), chalcosine (Cu2S) and molybdenite (MoS2).  A secondary enrichment zone is also found with thicknesses between 0 and 150 meters.

Concentrator

Our Toquepala concentrator operations use state-of-the-art computer monitoring systems in order to coordinate inflows and optimize operations. Material with a copper grade over 0.40% is loaded onto rail cars 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 in order 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.

Copper oxides from Cuajone with a copper grade higher than 0.208%, with an acid solubility index higher than 43% and a cyanide solubility index higher than 17% are leached. In Toquepala, the leach material cutoff grade is 0.153% and therefore material with a total copper grade between 0.153% and 0.300% are 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 the ISO 9001-

36

2008 standard. In 2012, we obtained the certification OHSAS 18001 of our occupational health and safety system and the ISO14001-2004 for our environmental standards at the SX-EW plant.

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 1,240 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 which we ship our product and receive supplies. Product 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. Copper produced by the smelter exceeds the refinery’s capacity and 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 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 to remove sulfur with compressed air injected into the bath. Finally, the oxygen content of the molten copper is adjusted by reduction with injection of 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 in general repair.

The table below sets forth 2014, 2013 and 2012 production and sales information for our Ilo smelter plant:

Key:kt = thousand tons

The off gases from the smelter are treated to recover over 92% of the incoming sulfur received in the concentrates producing 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.

37

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 being made 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 280,000 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 in order to dissolve copper which is deposited on initially very thin starting sheets increasing its thickness to produce high grade copper cathodes. During this process, silver, gold and other metals, including palladium, platinum and selenium, along with other impurities, settle on 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 which provides sample analysis throughout the Company, a maintenance department, a desalinization plan and other support facilities.

Other facilities in Ilo are a coquina plant with a production capacity of 200,000 tons per year of seashells and a lime plant with a capacity of 80,000 tons per year.  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 maintenance and repair of the car fleet. Annual tonnage transported is approximately 5.1 million tons.

MEXICAN OPEN-PIT SEGMENT

Our Mexican open-pit segment operations combine two units of Minera Mexico, La Caridad and Buenavista, which include La Caridad and Buenavista mine complexes and smelting and refining plants and support facilities, which service both complexes.

Following is a map indicating the approximate location of, and access to, our Mexican open-pit mine complexes, as well as our processing facilities:

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, a concentrator 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. 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 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 2010, a strike of approximately three years was settled and full production was restored in 2011. In 2013, mine operations were affected by flooding problems caused by unusual rains in the area, as a consequence we lost approximately 22,900 tons of copper production. The mine restored full operations by the end of the third quarter of 2013.

40

In August 2014, a spill of copper sulfate solution occurred at a leaching pond for Buenavista’s new SX-EW III plant. The solution reached the Bacanuchi River, a tributary of the Sonora River. We took immediate action to contain the spill and expedite the cleanup, also to comply with all the legal requirements. A trust fund of two billion pesos (approximately $150 million) was established to support remedial action and provide compensation to those adversely affected by this accident. In 2014, Buenavista deposited one billion pesos (approximately $74.9 million) in the trust, which are available to compensate claims as they arise. A technical committee, comprised of government representatives, Company personnel and specialists assisted by a team of environmental experts, was created to manage the fund.  We believe that most of the damage caused by the spill has been corrected.

We have started a major capital investment program at Buenavista, which includes our third SX-EW plant with a planned annual capacity of 120,000 tons of copper, which started operations in June 2014, producing 32,927 tons of copper cathodes in 2014; a concentrator expansion with an increase in production capacity of 188,000 tons per year; and two molybdenum plants with a combined annual capacity of 4,600 tons. This investment program is underway and we expect to complete it in two phases. The first phase was completed in 2014 and we expect to complete the second phase in 2015 with an expected further increase in annual copper production of 188,000 tons. With these investments, we expect the total production capacity at Buenavista will reach 488,000 tons of copper by the end of 2015.

The concentrator has a nominal milling capacity of 76,700 tons per day. The SX-EW facility has 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. Two leach ore crushers and the corresponding belt conveying systems are used to convey the leachable material to the heaps. Likewise, run-off mine leachable ore is hauled by trucks to the leach dumps.

The following table shows 2014, 2013 and 2012 production information for Buenavista:

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

41

age, lithologically correlated with a similar section in southeastern Arizona, uncomformably overlies Precambrian granite basement. The entire section was covered by volcanic rocks of Mesozoic age and later intruded by deep seated granodiorite batholith of Tertiary age, with further quartz monzonite porphyry differentiates of 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 a 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 significant increase in copper grades. Similar porphyry copper deposits usually contain lower grades at depth. The district is also unique for the occurrence of high-grade breccia pipes, occurring in clusters following the trend of the district.

Current dimensions of the mineralized ore body are 5x3 kilometers, and projects to more than 1 kilometer at depth. Considering 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 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, as well as areas where leach and waste dumps will be deposited. A total of 28,369 meters of core drilling were completed in 2011. 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 have a drilling campaign in 2013. In 2014, we performed a drilling program of 20,000 meters in order to verify the reserves. For 2015, we plan to drill 15,000 meters to define reserves and to confirm copper and molybdenum grades.

Concentrator

Buenavista uses state-of-the-art computer monitoring systems at the concentrator, the crushing plant and the flotation circuit in order to coordinate inflows and optimize operations. 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 and bar 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 27%. Concentrates are then shipped by rail to the smelter at La Caridad.

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 recovery of 85% and 50% of molybdenum content. The molybdenum plant consists of thickeners, homogenizer tanks, flotation cells, column cells and a holo-flite dryer.

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.

42

The Buenavista unit currently maintains 18.1 million cubic meters of pregnant leach solution in inventory with a concentration of approximately 1.82 grams of copper per liter.

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 3 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 will produce copper cathodes of LME grade A. Please see “Capital Investment Program” under Item 7 for further information.

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. 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, the smelter in 1986, the first sulfuric acid plant in 1988, the SX-EW plant in 1995, the second sulfuric acid plant in 1997, the copper refinery in 1997, the rod plant in 1998, the precious metals refinery in 1999 and the dust and effluents plant in 2012.

Geology

The La Caridad deposit is a typical porphyry copper and molybdenum deposit as seen also 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 relative low waste-stripping ratio, natural pit drainage and relative short haul for both ore and waste. The mining method involves drilling, blasting, loading and haulage of ore mill and waste to the primary crushers and the leach materials and waste to dumps, respectively.

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 completes 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 which have 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 30 years. The extent of the model area is approximately 6,000 meters by 4,000 meters with elevation ranging from 750 to 1,800 meters. Sixteen drilling campaigns have been conducted on the property since 1968. These campaigns drilled a total of 3,317 drill holes: 1,154 were diamond drill holes and 2,163 were reverse circulation. We have also drilled some hammer and percussion drill holes. A total of 634,080 meters have been drilled through December 2011.

In 2008, La Caridad finished a large exploration program of 50,000 meters. The target was to reach to the 900 level in order to reduce the drilling space and to define the copper and molybdenum mineralization continuity and also carry out metallurgical testing for the flotation and leaching processes. There was no exploration program between 2009 and 2011. In 2012, we drilled 10,000 meters and further defined the extent of the copper and molybdenum mineralization. There was no exploration program in 2013 and 2014. For 2015, we plan to conduct a 10,000 meter drilling program to define a high grade ore body located in the south western edge of the pit.

Concentrator

La Caridad uses state-of-the-art computer monitoring systems at the concentrator, the crushing plant and the flotation circuit in order to coordinate inflows and optimize operations. The concentrator has a current capacity of 91,000 tons of ore per day.

Ore extracted from the mine with a copper grade over 0.30% is sent to the concentrator and is 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 693.7 million tons of leaching ore with an average grade of approximately 0.246% copper have been extracted from the La Caridad open-pit mine and deposited in leaching dumps from May 1995 to December 31, 2013. All copper ore with

44

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 processing of this ore and certain leach ore reserves that were not mined and has resulted in a 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 94 electrowinning cells distributed in one 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 and a copper rod 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 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.

Almost 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 Buenavista, and starting in 2010, the concentrates from the IMMSA mines, as we closed the San Luis Potosi smelter.

The anode production capacity is 300,000 tons per year.

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 copper cathode of 99.99% purity. Anodic slimes are recovered from the refining process and sent to the slimes treatment plant where additional copper is extracted. The slimes are then filtered, packed and shipped to the La Caridad precious metals refinery to produce silver and gold.

The operations of the precious metal refinery begin with the reception of slime from silver concentrates, 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, besides 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 was completed 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%.

Other facilities include a lime plant with a capacity of 132,000 tons per year, two sulfuric acid plants with capacity of 2,625 and 2,135 tons per day, three oxygen plants each with a production capacity of 275 tons per day; and two power turbo generators.

In 2012, we started operating a dust and effluent plant with a treatment capacity of 3,100 tons per year which will produce 720 tons of copper by-products and 11,000 tons of lead per year. This plant is designed to reduce dust emissions from La Caridad metallurgical complex.

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.

Mine exploration in 2014 included 38,643 meters of surface diamond drilling and 16,893 meters from underground stations, which increased our reserves by 1,474,964 tons. For 2015, 30,000 meters of surface 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) and 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 2014 included 46,000 meters of surface diamond drilling and 15,231 meters from underground stations, which increased reserves by 4,084,041 tons. For 2015, 46,000 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 mineralization corresponds in its majority 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 2014 included 17,300 meters of surface drilling. For 2015, a 20,000 meters of diamond drilling program is planned to identify additional reserves.

In May 2010, the Santa Eulalia mine suspended operations due to a flooding in the area brought on by the failure of a dike caused by excess water pressure. The rehabilitation work was completed in April 2013, allowing us to restore production until it was interrupted by another flood in the third quarter 2014.

San Martin

San Martin has been on strike since July 2007. Please see Note 13 “Commitments and Contingencies — Labor matters” to our consolidated financial statements.

The San Martin mining complex is located in the municipality of Sombrerete in the western part of the state of Zacatecas, Mexico. Access to the property is via a federal highway between the cities of Durango and Zacatecas. It was discovered in 1555

47

and mining operations in the 20th century began in 1949. The complex includes an underground mine and a flotation plant and produces lead, copper and zinc concentrates, with significant amounts of silver. Regarding its geology, economic ore is found as replacement ore bodies which includes chalcopyrite (CuFeS2), sphalerite (ZnS), galena (PbS), bornite (Cu5FeS4) and others. There was no mine exploration drilling in the three years ended December 31, 2014 because of the strike.

Taxco

Taxco has been on strike since July 2007.  Please see Note 13 “Commitments and Contingencies — Labor matters” to our consolidated financial statements.

The Taxco mining complex 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 and produces lead and zinc concentrates, with some amounts of gold and silver. Regarding its geology, economic ore is found in the deposits in veins and includes argentiferous galena (PbS), sphalerite (ZnS), pyrargyrite (Ag3SbS3), and other sulfosalts. The most mineralized zones are in the vicinity of the veins with the limestone.

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% zinc), high grade zinc (over 99.9% zinc) 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.

The table below sets forth 2014, 2013 and 2012 production information for our San Luis Potosi zinc refinery:

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 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

48

capable of producing 100,000 tons of coke per year (metallurgical, nut and fine) of which, 95,000 tons are metallurgical coke. There is also a by-product plant to clean the coke gas oven in which tar, ammonium sulfate and light crude oil are recovered. There are also two boilers, which produce 80,000 pounds of steam that is used in the by-products plant. We believe the plant’s equipment is in good physical condition and suitable for our operations.

Coke production is sold to Penoles and other Mexican consumers in northern Mexico. We sold 90,796 tons, 76,831 tons and 69,638 tons of metallurgical coke in 2014, 2013 and 2012, respectively. We expect to sell 84,622 tons of metallurgical coke in 2015.

Carbon mine exploration

In Coahuila, an intensive exploration program of diamond drilling 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, that could be used for a future coal-fired power plant. In 2013 we drilled 2,451 meters and increased our coal reserve estimate by 39,552 tons at the La Conquista pit.  During 2014, we executed 3,100 meters of diamond drilling and 300,000 tons of additional reserves were determined. For 2015, we expect to execute a drilling program of 3,000 meters.

ORE RESERVES

Ore reserves are those estimated quantities of proven and probable material that may be economically mined and processed for extraction of their mineral content, at the time of the 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 sufficiently close enough and the geological characteristics of the deposits are sufficiently well defined to render the estimates reliable. The ore reserves 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

49

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 in order 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 which 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)).

Annually our engineering department reviews in detail the reserve computations. 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, reserves estimates in this report use $3.36 per pound for copper and $11.39 per pound for molybdenum, both current prices as of December 31, 2014. The current prices for copper and molybdenum were $3.65 and $12.74 as of December 31, 2013 and $3.68 and $14.52 as of December 31, 2012, respectively.

For internal ore reserve estimation, our management uses long-term metal price assumptions for copper and molybdenum. At December 31, 2014, we are using $2.90 per pound of copper and $9.50 per pound of molybdenum which we believe to be conservative prices for long-term trends.  At December 31, 2013 we considered $2.00 per pound of copper and $12.00 per pound of molybdenum. For other forecast and planning purposes, particularly related to merger and acquisition activities, our management considers various other price scenarios. The use of these other price assumptions does not affect the preparation of our financial statements.

For the years 2014, 2013 and 2012, we have used reserve estimates based on current average prices as of the most recent three year 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.

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 2014 are as follows:

	Long Range Model		Mill		Variance
Mine	Tons (thousands)	% Copper	Tons(thousands)	% Copper	Tons (thousands)		% Copper
Cuajone	30,574	0.662	30,555	0.680	19		(0.018	)
Toquepala	20,835	0.592	19,922	0.626	913		(0.034	)
Buenavista	28,207	0.576	27,291	0.581	916		(0.005	)
La Caridad	34,040	0.339	34,251	0.343	(211	)	(0.004	)

If the estimation error appears greater than 3%, a detailed evaluation is done to review the differences, which normally could result in more in-fill drilling, in order to better understand the geological characteristics (grade, rock type, mineralization and alteration) and the spacing of drill holes which are considered in the ore body zone.

AVERAGE DRILL-HOLE SPACING

The following is the average drill-hole spacing for proven and probable sulfide reserves as of December 31, 2014:

	Proven	Probable
	(average spacing in meters)
Cuajone	77.56	119.78
Toquepala	78.32	116.31
Buenavista	53.13	105.77
La Caridad	46.52	104.71

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 $74.6 million in exploration programs in 2014, $51.0 million in 2013 and $47.9 million in 2012 and we expect to spend approximately $45.8 million in exploration programs in 2015.

Currently, we have direct control of 81,245 and 164,237 hectares of exploration concessions in Peru and in Mexico, respectively. We also currently hold 174,831 hectares, 40,758 hectares and 2,544 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%. We expect to initiate an environmental impact assessment in 2015.

55

Other Peruvian Prospects. During 2014, we concluded the evaluation of the Lagarto project, which is located in the north of the Lima region. After completing our diamond drilling program at this prospect, we decided not to pursue further work on this property. Also, as part of the 2014 work plan, we drilled 22,907 meters at Los Algarrobales, which is located in the south coast of Peru.

For 2015, we plan to continue, and further develop a diamond drilling program of 40,000 meters at several other Peruvian mineralized zones, where we are exploring for a copper porphyry system. We also plan to continue with the regional exploration program at several different metallogenic zones of Peru.

Mexico

In addition to exploratory 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 forms part of the Buenavista ore body. Drilling and metallurgical studies have shown that the zinc-copper deposit contains approximately 36 million tons of mineralized material containing 29 grams of silver per ton, 0.69% copper and 3.3% zinc. A “scoping level” study indicates that Buenavista-Zinc may be an economic deposit. In 2011, 11,956 meters of diamond drilling were executed to confirm grade and acquire geotechnical information. In 2012, the Buenavista-Zinc mine plan was integrated with the overall mine plan of the Buenavista pit. The metallurgical testing was completed early in 2013 indicating some recovery problems with oxidized zinc. During 2013, we drilled 15,128 additional meters to locate the oxidized zinc for new modelling and metallurgical testing. In 2014, we received the results of the metallurgical testing and we adjusted our estimation of mineralized material to 75.6 million tons with an average zinc content of 2.06%, 0.58% of copper and 20.8 grams of silver per ton. In 2015, we plan to conduct a diamond drilling program of 29,000 meters and new metallurgical tests.

The Chalchihuites. The Chalchihuites site is located in the state of Zacatecas. It is a replacement deposit with mixed oxides and sulfides of lead, copper, zinc and silver. In the late 1990s, a drilling program defined 16 million tons of mineralized material containing 95 grams of silver per ton and lead content of 0.36%, copper content of 0.69% and zinc content of 3.08%. Preliminary metallurgical testing indicates that a leaching precipitating-flotation recovery process can be applied to this ore. In 2009, we started a prefeasibility study, which we expect to complete early in 2014. In 2010 and 2011, we added several claims and performed a 9,386 meter drilling program that indicated at least seven million tons of mineralized material containing 97.9 grams of silver per ton, 0.41% lead, 0.52% copper and 2.53% zinc. In 2013, we continued with the process to obtain all permits and the land acquisition required for the project.  During 2014, we failed to obtain the authorization for drilling from SEMARNAT (Federal Agency of Environment and Natural Resources). In 2015, we expect to obtain that authorization and conduct a drilling program of 20,000 meters.

Sierra de Lobos. This project is located southwest of the city of Leon, Guanajuato. Drilling in 2008 confirmed the presence of copper and zinc mineralization, but an economic deposit has not yet been identified. The project was on hold between 2010 and 2011 due to the changes in our investment program priorities. In 2012, we obtained all required permits and started drilling activities. In 2013, we drilled 3,945 meters. Although we identified some mineralized ore, they were not continuous. In 2014, we reviewed the results and decided not to pursue further work on this property.

Chile

Catanave. Located in northern Chile (Arica), Catanave belongs to a mineralized epithermal system of gold and silver. In 2010, the environmental impact study was approved. Between 2011 and 2013 diamond drilling programs were completed. We are still evaluating the results of the drilling programs to decide the future of the project.

El Salado. A copper-gold prospect located in the Atacama region, northern Chile is being explored for copper and molybdenum porphyry. In 2014, we completed a diamond drilling program of 12,000 meters focused on classifying the existing mineral. A further diamond drilling program of 5,000 meters is planned for 2015.

Resguardo de la Costa. A copper-gold prospect located in northern Chile (Atacama area). This prospect continues on hold, pending further evaluation.

56

Other Chilean Prospects.  For 2015, we plan to continue with an exploration program, principally in the north of Chile, focused on locating systems, mainly of porphyritic copper and molybdenum. In this region, we also plan a diamond drilling of 6,000 meters at the Iglesia prospect, to identify gold mineralization.

Ecuador

In 2011, we started exploration activities in Ecuador.

Chaucha: the Ruta del Cobre (“Copper Road”) project is located south of Guayaquil. The mineralization is characteristic of a copper-molybdenum porphyry system. In 2013, we obtained all the permits required for the evaluation of the deposit. In 2014, we conducted a diamond drilling program of 21,000 meters, and obtained favorable results indicating copper content of 0.40% and molybdenum content of 0.027%.  In 2015, we plan to conduct a diamond drilling program of 20,000 meters.

Argentina

In 2011, we started exploration activities in Argentina. During 2014, we performed geological exploration in the Salta, Rio Negro and Neuquen provinces where we expected to locate copper porphyry with precious metals epithermal systems. Also in 2014, we conducted a diamond drilling exploration program of 8,000 meters at the Cerro Sementa project, located in the Salta Province, where we located low grade copper and molybdenum mineralization. As a result, we will not pursue further exploration activities in this area. For 2015, we plan to continue with the regional exploration at Piuquenes, La Voluntad and Cochicos located in the San Juan and Neuquen provinces, where we expect to locate porphyry copper and molybdenum mineralization.

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, 2014. 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,” 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 with our principal operations in Peru and Mexico. We also have an active ongoing exploration program in Chile, Argentina and Ecuador. In addition to copper, we produce significant amounts of other metals, either as a by-product of the copper process or in a number of dedicated mining facilities in Mexico.

In 2014, we invested $1,534.8 million in capital programs along with $74.6 million in our exploration efforts. We believe this commitment to growth will continue to benefit our Company, our investors, our neighboring communities, and the countries in which we operate.

We believe we hold the world’s largest copper reserve position. At December 31, 2014, our copper ore reserves totaled 69.9 million tons of contained copper, calculated at a copper price of $2.90 per pound, our internal ore reserve estimation value is as follows:

Copper contained in ore reserves	Thousand tons
Mexican open-pit	34,266
Peruvian operations	23,719
IMMSA	213
Development projects	11,748
Total	69,946

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

·Changes in copper, molybdenum, silver and zinc prices: In 2014, the average LME copper price was $3.11 per pound and the average COMEX copper price was $3.12 per pound, about 6.3% and 6.6% lower than in 2013, respectively. In 2014, per pound LME spot copper prices ranged from $2.86 to $3.37. Average molybdenum and zinc prices in 2014 increased 10.1% and 12.6%, respectively, compared to 2013. Average silver prices in 2014 decreased 20.1% compared to 2013.

·Sales structure: In the last three years, approximately 78% of our revenues came from the sale of copper, 7% from molybdenum, 6% from silver, 3% from zinc and 6% from various other products, principally sulfuric acid and gold.

63

·Copper: Regarding the copper market, we believe the recent reduction in copper prices results from copper following oil for technical reasons, not related to the copper market or fundamentals. We also believe the current relative softness in copper prices will start to change as we move into the second quarter of 2015.

As we have indicated in the past, we believe short-term copper demand is consistently improving. For 2015, we expect the improvement in the U.S. economy to keep pulling new copper demand. We also believe we will see higher demand coming from Western Europe. China’s growth is expected to be limited by its housing market slowdown, however, the Chinese electric grid plans to expand investments by 24%, will support copper demand growth of about 4% for China.

On the supply side, we think that several structural factors will continue to affect supply from new projects and existing operations, as well as scrap production. The current views by analysts on the 2015 copper market ranges between balance and a surplus of 300,000 tons surplus. In the majority of these estimates, surplus expectations are significantly down from a year ago. Due to such factors as delays in project startups, technical problems, labor unrest and other difficulties, we believe the market will trend to balance as we move through 2015.

We want to emphasize that prices at current levels are not sufficient to promote the necessary future supply growth, for which reason we believe that in the long-term, prices will increase to meet those needs, thereby improving the strong long term fundamentals of our industry.

·Molybdenum: Our most significant by-product, represented 8.8% of sales in 2014. In the fourth quarter of 2014, we saw a price deterioration for molybdenum consistent with our outlook of a 10% worldwide supply growth in 2015 coming from our Buenavista operation, as well as from Sierra Gorda, Toromocho and Caserones, among other projects.

Demand for molybdenum will be affected in 2015 by lower demand for special alloys coming from the oil drilling industry. This will add to the above mentioned supply issues.

Even though the current scenario for molybdenum prices is not positive, it is important to note that about 50% of the supply of this metal comes from primary or dedicated molybdenum mines, which have a cash cost in the range of $9-$12 per pound. This creates a natural barrier for the molybdenum market to adjust production volume and thereby protect low cost secondary molybdenum producers such as our Company.

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

·Silver: Represented 4.7% of our sales in 2014 and it is currently our second most significant by-product. Silver prices averaged $19.04 per ounce in 2014, 20.1% lower than its price in 2013. 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.

·Zinc: Represented 3.6% of our sales in 2014. We also believe that zinc has very good long-term fundamentals due to its significant industrial consumption and expected mine production shutdowns. In the last 12 months, zinc inventories have consistently decreased, improving this market’s fundamentals. We are expecting an increasing price scenario for zinc in the next few years.

·Production: For 2015, improvements in operational practices and capital investments will reduce costs and increase the Company’s copper and molybdenum production. We plan to produce 782,300 tons of copper, which will set a new record for SCC copper production. Additionally, during the fourth quarter of 2014, we completed the construction of a new SX-EW plant that is expected to significantly increase production of leachable material by approximately 120,000 tons per year.

For this guidance we are considering that our Buenavista operation will produce 344,700 tons. Of those, a total of 163,300 tons will come from our new projects. The SX-EW III plant will contribute with 102,300 tons and the new concentrator at Buenavista will add 61,000 tons.

We expect to produce 21,500 tons of molybdenum in 2015, 7% lower than our 2014 production, this variance is due to lower ore grades and recoveries at our operations.

64

In 2015, we also expect to produce 12.7 million ounces of silver and produce 86,200 tons of zinc, an increase of almost 20,000 tons of zinc compared to 2014.

·Cost: Our operating costs and expenses for the three-years ended December 2014 have increased in total in each of the years. Our comparison of costs for the three year period is as follows:

	2014			2013			2012(*)
Operating costs and expenses (in millions)	$	3,554.9		$	3,420.8		$	3,244.2
Percentage increase from prior year	3.9		%	5.5		%	1.6		%

(*) Operating costs and expenses for 2012 does not include a one-time expense of $316.2 million, for legal fees related to a shareholder derivative lawsuit. Accordingly, operating costs and expenses for 2012 is a non-GAAP measure, please see subheading “Non-GAAP information reconciliation”, for a reconciliation of this to a GAAP measure in this Item 7.

Operating costs and expenses in 2014 increased $134.1 million, compared to 2013, principally due to a $91.4 million environmental remediation provision for the spill at Buenavista, higher depreciation, amortization and depletion at our operations and higher exploration spending.

Operating costs and expenses in 2013 increased $176.6 million, compared to 2012 mainly due to higher cost of sales that was largely caused by the higher cost of fuel, power and labor. The sharp decrease in the purchase and sale of third-party metal concentrates in the 2013 and 2012 years, helped reduce cost of sales; but higher depreciation, caused by the completion and placing in service of some capital assets for both our Buenavista expansion program and our maintenance programs offset those reductions in overall operating costs.

·Capital Expenditures: Capital expenditures were $1,534.8 million for 2014, 114.7% of net income and 9.9% lower than in 2013. Our growth program to develop the full production potential of our Company is fully underway.

For 2015, we plan to invest $2.7 billion in capital projects, an increase of $1.2 billion compared to 2014 and 201.6% of 2014’s net income. As we have previously reported, our investment program aims to increase copper production capacity by approximately 89% from our 2013 production level of 617,000 tons to 1,165,000 tons by 2018.

The $2.7 billion investment will be mainly to (i) complete the expansion of the Buenavista mine, which will reach a production capacity of 488,000 tons of copper per year; (ii) expansion of Toquepala which will increase annual production capacity by 100,000 tons of copper and; (iii)  construction of our Tia Maria project which will produce 120,000 tons of copper cathodes per year.

·      Buenavista del Cobre copper solution spill: On August 6, 2014, an accidental spill of approximately 40,000 cubic meters of copper sulfate solution occurred at a leaching pond that was under construction ten kilometers away from the mine of Buenavista del Cobre, S.A. de C.V. (“BVC”), a subsidiary of the Company. The accident was caused by a rock collapse that affected the system’s pumping station and by a construction defect in the seal of a pipe in the leaching system containment dam, a part of the new SX-EW III plant. This solution reached the Bacanuchi River, a branch of the Sonora River. All the immediate actions were properly taken in order to contain the spill, and to comply with all the legal requirements.

On September 15, 2014, BVC, in agreement with the Mexican Federal Government, established a trust of up to two billion pesos (approximately $150 million) to support the remedial efforts that BVC had already undertaken, to comply with the environmental remediation plan and to pay, as the case may be, material damages to the riverside residents of the seven counties affected by the spill. In 2014, BVC estimated the contingent liability at $91.4 million, of which $16.4 million had been paid previous to the establishment of the trust, and approximately one billion pesos (approximately $74.9 million) was deposited in the trust. These funds have been available and have been used to compensate claims as they have arisen. This deposit was classified as restricted cash and was recorded as an operating expense in the 2014 results. A technical committee was created to manage the funds, comprised of representatives from the federal government, the Company and specialists assisted by a team of environmental experts. The trust established by the Company and the administrative agreement executed with the corresponding Federal authorities, serves as an alternative mechanism for dispute resolution to mitigate public and private litigation risks.

KEY MATTERS

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

Earnings: The table below highlights key financial and operational data of our Company for the three years ended December 31, 2014 (in millions, except per share amounts):

	Year						Variance
	2014		2013		2012		2014-2013			2013-2012
Net sales	$	5,787.7	$	5,952.9	$	6,669.3	$	(165.2	)	$	(716.4	)
Operating income	2,232.8		2,532.1		3,108.9		(299.3		)	(576.8		)
Net income attributable to SCC	$	1,333.0	$	1,618.5	$	1,934.6	$	(285.5	)	$	(316.1	)
Earnings per share	$	1.61	$	1.92	$	2.28	$	(0.31	)	$	(0.36	)
Dividends per share	$	0.46	$	0.68	$	4.06	$	(0.22	)	$	(3.38	)
Pounds of copper sold	1,448		1,382		1,415		66			(33		)

Net sales decreased in the three-year period from 2012 to 2014, due to lower metal prices for copper and silver, partially offset by an increase in copper and molybdenum sales volumes. The 2014 copper and molybdenum sales volume increased by 4.7% and 16.1%, respectively.

The two largest components of operating costs and expenses are cost of sales and depreciation, amortization and depletion, the latter of which increased in each of the years in the periods above. In 2014, cost of sales decreased by $30.8 million and depreciation, amortization and depletion increased by $49.0 million. The decrease in cost of sales was due to lower cost of metals purchased from third parties, labor costs, workers’ participation expense, mining royalties, net currency translation effect and inventory consumption. The increase in depreciation was mainly due to maintenance capital acquisitions at most of our operations. The 2012 operating cost includes a charge of $316.2 million for legal fees related to our shareholders derivative lawsuit. This unique charge affects 2012 with no equivalent charge in the other years. In addition, the 2014 operating results include a charge for costs of remediating the spill at Buenavista.

Net income in 2014 was 17.6% lower mainly due to the above noted factors.

Production: The table below highlights, mine production data of our Company for the three years ended December 31, 2014:

2014 compared to 2013:

Mined copper in 2014 increased 131.3 million pounds, compared to 2013 production. This increase was due to:

·Higher production at our Buenavista mine due to higher throughput at the concentrator and better ore grades and recoveries, as well as higher production from the SX-EW III plant.

·Higher production at the Toquepala mine and La Caridad mine due to better ore grades and recoveries.

·Higher production at the Cuajone mine resulting from higher ore grades and increased throughput from the HPGR production, partially offset by

·lower production at IMMSA mines due to problems at the Charcas and Santa Eulalia mines; an accident occurred at the Charcas mine that temporarily restricted production while the Santa Eulalia mine experienced flooding problems.

Molybdenum production increased 7.1 million pounds in 2014, compared to 2013, mainly at our Buenavista and Toquepala mines. Zinc mine production from our IMMSA unit in Mexico, decreased by 72.2 million pounds in 2014, 33.0% lower than in 2013, mainly as a result of lower grades at all our IMMSA mines and lower production at the Charcas and Santa Eulalia mines, as discussed above.

Our silver production decreased in 2014, compared to 2013 production, due to lower production at the IMMSA mines offset by higher production at the Toquepala, Cuajone, Buenavista and La Caridad mines.

2013 compared to 2012:

Mined copper in 2013 decreased 45.6 million pounds, compared to 2012 production.  This decrease was due to:

·Lower production at our Buenavista mine, which experienced temporary flooding problems.

·Lower production at the Toquepala mine due to lower ore grades and throughput at the concentrator, and

·lower SX-EW production because of a decrease in PLS grades, all partially offset by,

·higher production at the Cuajone mine resulting from higher ore grades and recoveries.

Molybdenum production increased 3.6 million pounds in 2013, compared to 2012. Molybdenum production increased at all our mines. La Caridad mine reached a new record production of 25.9 million pounds in 2013 compared to the prior year record of 24.2 million pounds. Additionally, the new Buenavista molybdenum plant which started commercial production by the end of the third quarter 2013, produced 0.8 million pounds of molybdenum.

Zinc mine production from our IMMSA unit in Mexico, increased by 20.9 million pounds in 2013, 10.6% higher than in 2012, mainly as a result of higher recoveries and a full year of production at the Santa Eulalia mine after the flooding problems of prior years were resolved.

Our silver production decreased slightly in 2013 compared to 2012 production due to lower production at the Toquepala, Buenavista and La Caridad mines offset somewhat by higher production at the Cuajone and IMMSA 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 to the cost of sales (exclusive of depreciation, amortization and depletion) as

67

presented in the consolidated statement of earnings is presented under the subheading, “Non-GAAP Information Reconciliation,” beginning on page 88. We disclose operating cash cost per pound of copper produced, both without and with the inclusion of by-product revenues.

We define operating cash cost per pound of copper produced without 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. Additionally excluded 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 consider is one of the lowest of copper producing companies of similar size.

We define operating cash cost per pound of copper produced with by-product revenues as operating cash cost per pound of copper produced, as defined above, less by-product revenues and net revenue (loss) on sale of metals purchased from third parties.

In our calculation of operating cash cost per pound of copper produced, with 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 process of copper purchased from third parties, are a marginal part of our production process and their sales value contribute to cover 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, without by-product revenues allows us to monitor our cost structure and address with operating management areas of concern as copper is our main source of revenues.

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

Our operating cash cost per pound of copper produced, as defined above, is presented in the table below for the three years ended December 31, 2014:

2014 compared to 2013:

As seen on the chart above, our 2014 operating cash cost per pound of copper produced without by-product revenues was slightly lower than in 2013, a decrease of 0.5% mainly due to the diluting effect on unit cost of higher production at all our open pit mines, more significantly from Buenavista. This increase in production volume offset the cost of higher inflation, which increased fuel, power and other operating materials for our production process.

Our cash cost per pound for 2014 when calculated with by-product revenues was $1.05 per pound, compared to $1.00 per pound in 2013.  The by-product credit in 2014 was six cents less than in 2013. This was due to lower prices for silver and gold, and lower sales volume of silver and zinc. Higher prices for zinc and molybdenum and higher sales volume for molybdenum and gold helped to offset some of the negative factors.

2013 compared to 2012:

As seen on the chart above, operating cash cost per pound of copper without by-product revenues was $0.17 per pound higher than in 2012, an increase of 9.8%, due to higher production cost. Production cost increases were primarily from Peruvian labor cost, as a result of the new collective bargaining agreements, and higher fuel and power costs. In addition, there were increases in some of the other operating material we use in our operations, including tires, explosives and reagents.

Our cash cost per pound for 2013 when calculated with by-product revenues was $1.00 per pound, compared to $0.71 per pound in 2012.  In addition to the increase in production cost, lower sales prices of our main by-products reduced the positive contribution of by-product revenues.

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

We are subject to market risks arising from the volatility of copper and other metals prices.  For 2015, assuming that expected metal production and sales are achieved, that tax rates are unchanged and giving no effect to potential hedging programs, metal price sensitivity factors would indicate the following change in estimated annual net income attributable to SCC resulting from metal price changes:

	Copper		Molybdenum		Zinc		Silver
Change in metal prices (per pound except silver — per ounce)	$	0.10	$	1.00	$	0.10	$	1.0
Change in net earnings (in millions)	$	99.3	$	27.8	$	12.7	$	7.5

Business Segments: We view our Company as having three reportable segments and manage it on the basis of these segments. These segments are (1) our Peruvian operations, (2) our Mexican open-pit operations and (3) our Mexican underground operations, known as our IMMSA unit. Our Peruvian operations include the Toquepala and Cuajone mine complexes and the

69

smelting and refining plants, industrial railroad and port facilities that service both mines. The Peruvian operations produce copper, with significant by-product production of molybdenum, silver and other material. Our Mexican open-pit operations include La Caridad and Buenavista mine complexes, the smelting and refining plants and support facilities, which service both mines. The Mexican open-pit operations produce copper, with significant by-product production of molybdenum, silver and other material. Our IMMSA unit includes five underground mines that produce zinc, lead, copper, silver and gold, a coal mine which produces coal and coke, and several industrial processing facilities for zinc, copper and silver.

Segment information is included in our review of “Results of Operations” in this item and also in Note 18 “Segment and Related Information” of our consolidated financial statements.

Inflation and Exchange Rate Effect of the Peruvian Nuevo Sol and the Mexican Peso: Our functional currency is the U.S. dollar and our revenues are primarily denominated in U.S. dollars. Significant portions of our operating costs are denominated in Peruvian Nuevo sol and Mexican pesos. Accordingly, when inflation and currency devaluation/appreciation of the Peruvian currency and Mexican currency occur, our operating results can be affected. In recent years, we do believe such changes have not had a material effect on our results and financial position. Please see Item 7A “Quantitative and Qualitative Disclosures about Market Risk” for more detailed information.

Capital Investment Program: We made capital expenditures of $1,534.8 million, $1,703.3 million and $1,051.9 million in 2014, 2013 and 2012, respectively. In general, the capital expenditures and investment projects described below are intended to increase production, decrease costs or address social and environmental commitments.

In 2015, we plan to invest $2.7 billion in capital projects. As we previously disclosed, our investment program aims to increase copper production capacity by approximately 89% from our 2013 production level of 617,000 tons to 1,165,000 tons by 2018.  In addition to our ongoing capital maintenance and replacement spending, our principle capital programs include the following:

Projects in Mexico:

Buenavista Projects: We continue developing our $3.4 billion investment program at this unit which is expected to increase its copper production capacity by approximately 175%, as well as molybdenum production by 42%.

The new copper molybdenum concentrator has an annual production capacity of 188,000 tons of copper and 2,600 tons of molybdenum. The project will additionally produce 2.3 million ounces of silver and 21,000 ounces of gold per year. The total capital budget of the project is $1,383.6 million and through December 31, 2014, the project has an 92.2% progress with an investment of $978.5 million. The project is expected to be completed in the third quarter of 2015. All major equipment is on site and has been installed.

Regarding the mine equipment acquisition for the Buenavista expansion, through December 31, 2014 we have invested $510.9 million and have received sixty-one 400-ton capacity trucks, seven shovels and eight drills required for the mine expansion. All of this equipment is currently in operation.

Performance testing for the SX-EW III plant was successfully completed and technical full capacity has been achieved in accordance with the design flow rate of the plant. Estimated annual production for the plant is 120,000 tons of copper cathodes. Capital budget of $444.0 million has been invested through December 31, 2014.

The crushing, conveying and spreading system for leachable ore project (Quebalix IV) will increase production by improving SX-EW copper recovery, reducing processing time, mining and hauling costs. It has a crushing and conveying capacity of 80 million tons per year and is expected to be completed in the fourth quarter of 2015. The project has a 49.4% progress with an investment of $117.7 million out of the approved capital budget of $340 million.

The remaining projects to complete the $3.4 billion budgeted program include investments in infrastructure, including power lines and substations, water supply, tailings dam, mine equipment shops, internal roads and others.

Angangueo: With an estimated investment of $174.7 million, Angangueo includes a concentrator plant which will have an estimated average annual metal content production of 10,400 tons of copper and 7,000 tons of zinc in the first seven years. Over the life of the mine, average annual concentrate production is expected to contain 2.4 million ounces of silver and 1,500 ounces of gold. Through December 31, 2014 we have spent $27.3 million on the project. We are preparing the new environmental studies for this project. We will wait the authorization from SEMARNAT to resume the purchase of main equipment and work on the project.

Projects in Peru:

Toquepala Projects: Through December 31, 2014, we have invested a total of $346.0 million in Toquepala projects. These projects include the construction of a new crusher and conveyor belt system to replace current mine rail haulage, which we expect will reduce annual operating cost.

Toquepala expansion project. On December 17, 2014 we received governmental approval of the EIA for the Toquepala concentrator expansion, which will allow us to continue developing this important project. The Toquepala concentrator expansion will increase annual production capacity by 100,000 tons of copper and 3,100 tons of molybdenum at a total capital cost of approximately $1.2 billion.

Cuajone Projects: Through December 31, 2014, we have invested $40.6 million of a budget of $45 million on the HPGR project, which will produce a more finely crushed material. The engineering and the purchase of equipment have been completed and the project has reached 99% completion. The project is expected to generate cost savings, improve copper recovery and reduce power consumption in the crushing process. Through December 2014, the implementation of the HPGR project and the variable cut-off ore grade project, implemented in 2013, have produced an estimated incremental production of 23,500 tons of copper.

The project to improve slope stability at the south area of the Cuajone mine, will remove approximately 148 million tons of waste material, in order to improve mine design without reducing current production level. The mine equipment acquired includes one shovel, five 400-ton capacity trucks, one drill and auxiliary equipment which will be reallocated to our mine

71

operations once the project is finished. Besides preparing the mine for the future, this investment will avoid a reduction in average ore grade. As of December 31, 2014, 14 million tons of waste material have been removed and activities will continue for 4 additional years. At December 31, 2014, we have invested $67.7 million in this project.

Tia Maria project: On August 1, 2014 we received the final approval of our EIA. We expect to be granted the authorization in the first quarter of 2015 to move forward with the construction phase and begin construction immediately thereafter.

This project will be completed in the first half of 2017 with an investment of approximately $1.4 billion, to produce 120,000 tons of copper cathodes per year using state of the art technology with the highest international environmental standards. The project is currently expected to generate 3,500 jobs during the construction phase. When in operation, Tia Maria will directly employ 600 workers and indirectly another 2,000. Through its expected twenty-years of life, the project related services will create significant business opportunities in the Arequipa region.

In addition, the Company intends to implement social responsibility programs in the Arequipa region similar to those established in the communities near its other Peruvian operations.

Tailings disposal at Quebrada Honda: This project increases the height of the existing Quebrada Honda dam to impound future tailings from the Toquepala and Cuajone mills and will extend the expected life of this tailings facility by 25 years. The first stage and construction of the drainage system for the lateral dam is finished. We are preparing bidding documents for the second stage that includes engineering and procurement to improve and increase the dam’s embankment. The project has a total budgeted cost of $66.0 million, with $52.7 million invested through December 31, 2014.

Potential projects

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

El Arco: El Arco is a world class copper deposit in the central part of the Baja California peninsula, with ore reserves over 1.5 billion tons with an ore grade of 0.416% and 0.14 grams of gold per ton. In 2010, we concluded the feasibility study and an investment of $56.4 million was approved for land acquisition required for the project. This project, when developed, is expected to produce 190,000 tons of copper and 105,000 ounces of gold annually. Through December 31, 2014 we have invested $41.3 million on studies, exploration and land acquisition for the project. In 2015, we expect to continue investing in land acquisition and exploration. In addition, we will begin an engineering study to determine the best way to optimize the investment in the project.

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 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, leachable material and related amortization, estimated impairment of assets, asset retirement obligations, valuation allowances for deferred tax assets, unrecognized tax benefits and fair value of financial instruments. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

72

Ore Reserves: For internal ore reserve estimation, we use metal price assumptions of $2.90 per pound for copper and $9.50 per pound for molybdenum. These prices are intended to conservatively approximate average prices over the long term.

However, pursuant to SEC guidance, the reserve information in this report is calculated using average metals prices over the most recent three years, 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, 2014:

	2014	2013	2012	Average 2014-2012
Copper ($ per pound)	3.12	3.34	3.61	3.36
Molybdenum ($ per pound)	11.30	10.26	12.62	11.39

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 to 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, 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.”

Leachable Material:

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 on our balance sheet, current leach inventory (as part of work-in-process inventories) and long-term leach inventory. Through the third quarter of 2014, the cost attributed to the produced leach material was charged to cost of sales over a five-year period, which was the average estimated recovery period based on the recovery percentages of each mine. However, the improvements in efficiency in production and use of leachable material, as a result of the completion of construction of a new plant during the fourth quarter, resulted in a change in amortization of leachable material to the units of production method.  This was accounted for prospectively in 2014, and will better match costs with revenues resulting from the increases in production stemming from the new plant.  As the plant entered into operation in the fourth quarter of 2014, the impact to results in 2014 was not considered significant and totaled approximately $17 million recognized within cost of sales. The Company expects that the impacts in future periods will be significant as a result of the increased production levels.

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 amounts charged to operations for reclamation and remediation.

Asset retirement obligations are further discussed in Note 9 “Asset Retirement Obligation” to our 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 few cases perhaps a few further 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

73

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.

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 a long-term average copper price of $3.00 per pound of copper and an average molybdenum price of $10.00 per pound, reflective of the current price environment, for our impairment tests. 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 $8.00 per pound showed projected discounted cash flows in excess of the carrying amounts of long-lived assets by margins ranging from 2.20 to 4.76 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 reverse in the future with three year average prices 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 by reference to fair value.

2014-2013:  Net sales in 2014 were $5,787.7 million, compared to $5,952.9 million in 2013, a decrease of $165.2 million or 2.8%. The decrease was principally the result of lower copper and silver prices as well as lower silver and zinc sales volume, partially offset by higher molybdenum and zinc prices and higher copper and molybdenum sales volume. Copper made up 78.0% of net sales in 2014, compared to 78.2% in 2013. Sales of by-products in 2014 totaled $1,269.7 million, compared to $1,298.1 million in 2013, a decrease of 2.2%.

2013-2012:  Net sales in 2013 were $5,952.9 million, compared to $6,669.3 million in 2012, a decrease of $716.4 million or 10.7%.  The decrease was principally the result of lower copper prices and sales volume as well as lower prices for our major by-products partially offset by higher sales volume of molybdenum, zinc and silver. Copper made up 78.2% of net sales in 2013, compared to 77.0% in 2012.  Sales of by-products in 2013 totaled $1,298.1 million, compared to $1,532.4 million in 2012, a decrease of 15.3%.

2014-2013: Operating costs and expenses in 2014 increased $134.1 million, compared to 2013, primarily due to:

Operating cost and expenses for 2013		$	3,420.8
Plus:
·	Higher depreciation, amortization and depletion mainly at our Mexican operations as a result of the acquisition of mine equipment and the start-up of some projects, including the Quebalix IV project. In addition, higher depreciation at our Peruvian operations from addition of new equipment.	49.0
·	Higher exploration expenses mainly in South America.	23.6
·	Environmental remediation expense due to the spill at Buenavista.	91.4
·	Higher selling, general and administrative expenses.	0.9
Less:
·	Lower cost of sales (exclusive of depreciation, amortization and depletion), mainly as a result of lower purchases of metals from third parties, mining royalties, labor costs, workers’ participation, net currency translation effect, inventory consumption and others.	(30.8		)
Operating cost and expenses for 2014		$	3,554.9

76

2013-2012: Operating costs and expenses in 2013 decreased $126.7 million, compared to 2012, primarily due to:

Operating cost and expenses for 2012		$	3,560.4
Less:
·	Legal fees related to SCC shareholder derivative lawsuit in 2012.	(316.2		)
Plus:
·	Higher cost of sales (exclusive of depreciation, amortization and depletion), principally as a result of higher production cost (labor, fuel and power and repair material costs) and higher inventory consumption, partially offset by lower workers’ participation, mining royalties and cost of metals purchased from third parties.	102.1
·	Higher depreciation, amortization and depletion mainly at our Mexican operations as a result of the acquisition of mine equipment and the start-up of some projects, including the Quebalix III project.	70.2

2014-2013: Non-operating income and expense were a net expense of $164.1 million in 2014 compared to a net expense of $159.5 million in 2013. The $4.6 million increase in net expense in 2014 was mainly due to:

·$32.7 million of higher miscellaneous expenses principally at our Peruvian operations, including unrecovered insurance expense, and,

·$18.4 million income in 2013 from the return of funds from Coimolache, expended during the exploration stage of the Tantahuatay mine, partially offset by,

·$57.8 million of higher capitalized interest which decreased non-operating expense due to increased capital expenditures at our Mexican operations.

2013-2012: Non-operating income and expense were a net expense of $159.5 million in 2013 compared to a net expense of $135.4 million in 2012. The $24.1 million increase in 2013 was a net expense mainly due to:

·$63.7 million of higher interest expense as a result of the $1.5 billion notes issued in November 2012,

·$18.2 million less of a 2012 gain in the sale of our shares of Compania Internacional Minera, a mining company in which we had a minority participation, partially offset by

·$39.5 million of higher capitalized interest due to increased capital expenditures principally at our Mexican operations, and

·$18.4 million received in 2013 from Coimolache as a return of funds provided during the exploration stage of the Tantahuatay mine. These funds were originally expensed on our financial statements.

Income taxes

	2014			2013			2012
Provision for income taxes	$	754.6		$	769.3		$	1,080.9
Effective income tax rate	36.5		%	32.4		%	36.3		%

The income tax provision includes Peruvian, Mexican and U.S. federal and state income taxes.

77

Components of income tax provision for 2014, 2013 and 2012 include the following ($ in million):

	2014		2013		2012
Statutory income tax provision	$	630.6	$	743.8	$	1,031.3
Peruvian royalty	7.5		—		—
Mexican royalty	81.2		—		—
Peruvian special mining tax	35.3		25.5		49.6
Total income tax provision	$	754.6	$	769.3	$	1,080.9

The increase in the effective tax rate in 2014 from the prior year is primarily due to the new Mexican royalty tax instituted for 2014, which added 4.0% to the effective tax rate and the provision for environmental remediation, which is a non-deductible expense. The higher effective income tax rate in 2012 was principally due to a $316.2 million one-time payment of legal fees related to the SCC shareholder derivative lawsuit, which is being treated as a non-deductible expense.

In 2014, the Peruvian government enacted tax law changes to both the income tax and dividend tax rates that become effective on January 1, 2015. The rate in effect for 2014 was 30%, with a 4.1% dividend tax rate. The new rates are as follows:

Year	Income Tax Rate		Dividend Tax Rate
2015- 2016	28	%	6.8	%
2017- 2018	27	%	8.0	%
2019 and later	26	%	9.3	%

The recalculation of the deferred tax liability in the Peruvian jurisdiction using future tax rates did not have a material effect on the deferred tax liability and the Company’s financial statements.

In 2013, the Mexican Congress enacted tax law changes that became effective on January 1, 2014. Among other things the law maintains the statutory rate at 30%, eliminating rate decreases scheduled to take effect for 2014 and 2015. In addition, the law has made the tax consolidation rules more restrictive. The impact of these changes increased our deferred income tax provision in 2013 by $34.7 million. Please see Note 7 “Income taxes” for a more complete description of the tax changes.

Equity earnings of affiliate

In 2014, 2013 and 2012 we have recognized $23.9 million, $20.9 million and $48.7 million, respectively of equity earnings of affiliate, from 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 2014 was $5.0 million, compared to $5.7 million in 2013, and $6.7 million in 2012, decreases in 2014 and 2013 of $0.7 million and $1.0 million, respectively. These decreases were the result of lower earnings at our Peruvian operations.

Income attributable to SCC

Our net income attributable to SCC in 2014 was $1,333.0 million, compared to $1,618.5 million in 2013 and $1,934.6 million in 2012. Net income attributable to SCC decreased mainly as a result of the decrease in metal prices and other factors described above.

SEGMENT RESULTS ANALYSIS

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

Significant items were added to (deducted from) net income, to arrive at operating cash flow including depreciation, amortization and depletion, currency translation effect, equity earnings of affiliate net of dividends received and other adjustments.

2014: In 2014, net income was $1,338.0 million, approximately 99% of the net operating cash flow. An increase in operating assets and liabilities reduced operating cash flow by $129.7 million and included:

·$260.1 million increase in inventory mainly due to $206.9 million of higher long-term leachable material inventory, mainly at our Buenavista mine.

·$7.0 million increase in accounts receivable.

·$109.6 million increase in accounts payable and accrued liabilities which was mainly due to $72.6 of higher income tax provision, $56.4 million of higher accounts payable mainly at our Mexican operations which includes higher capital investment at our Buenavista projects, and $19.4 million of lower workers’ participation.

2013:  In 2013, net income was $1,624.2 million, approximately 88% of the net operating cash flow. An increase in operating assets and liabilities reduced operating cash flow by $68.7 million and included:

·$143.6 million increase in inventory mainly due to an increase of $126.9 million in leachable material.

·A decrease in accounts payable and accrued liabilities was mainly due to higher payment of income tax and workers’ participation than amounts accrued.

·$136.1 million decrease in accounts receivable.

2012:  In 2012, net income was $1,941.4 million, approximately 97% of the net operating cash flow. The principal adjustments to reconcile net income to cash include depreciation, amortization and depletion of $325.7 million less an increase in operating assets and liabilities which reduced operating cash flow by $287.6 million and included:

·$180.7 million increase in inventories which includes an increase of $120.6 million in capitalized leachable material.

Other Liquidity Considerations

We expect that we will meet our cash requirements for 2015 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, 2014, $37.7 million of our cash, cash equivalents, restricted cash and short-term investments of $722.0 million was 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 had provided a deferred tax liability of $7.4 million as of December 31, 2013 for the U.S. income tax effects of $76.2 million of foreign earnings that may potentially be repatriated in the future.  At December 31, 2014 Minera Mexico has determined that it has no remittable earnings available for dividends to the United States due to its internal financial obligations and current expansion, and that at the end of 2014 it has met the indefinite reversal criteria of ASC 740-30-25-17 that it intends to reinvest its earnings indefinitely. Any distribution of earnings from our Mexican subsidiaries to the United States is subject to a U.S. federal income tax that equates to approximately 10% of the amount of the distribution after considering foreign tax credit utilization. Distributions of earnings from our Peruvian branch to the United States are not subject to repatriation taxes. Our Peruvian operations are not foreign subsidiaries. Rather they are mainly comprised of operations that are treated as a branch of our U.S. operations from a tax perspective.

Share repurchase program: In 2008, our 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, 2014, we have purchased 79.9 million shares of our common stock at a cost of $1,842.3 million. These shares will be 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 29, 2015, the Board of Directors authorized a cash dividend of $0.10 per share of common stock payable on March 3, 2015, to shareholders of record at the close of business on February 17, 2015.

SCC shareholder derivative lawsuit: On October 9, 2012, we received from AMC, our majority shareholder, $2.1 billion in satisfaction of the judgment issued pursuant to the decision of the Court of Chancery of Delaware which concluded that we paid an excessive price to AMC in the 2005 merger between the Company and Minera Mexico, S.A. de C.V. From the aforementioned sum received from AMC, we paid $316.2 million to the plaintiff’s attorneys to satisfy the award of attorneys’ fees and expenses. The effect of these transactions was recorded in our 2012 results.

85

FINANCING

In November 2012, we issued $1.5 billion of fixed-rate unsecured notes with a discount of $22.5 million, which is being amortized over the term of the related debt.  This debt was issued in two tranches, $300 million due in 2022 at an annual interest rate of 3.5% and $1.2 billion due in 2042 at an annual interest rate of 5.25%. Net proceeds are being used for general corporate purposes, including the financing of our capital expenditure program.  In 2013, World Finance, an international business magazine, recognized this debt as the best international debt issuance of the year in the mining industry.

Our total debt at December 31, 2014 was $4,206.0 million, compared to $4,204.9 million at December 31, 2013, net of the unamortized discount of notes issued under par of $45.1 million and $46.2 million at December 31, 2014 and 2013, respectively.

The ratio of total debt to total capitalization was 41.8% at December 31, 2014, compared to 43.1% at December 31, 2013.  Also the ratio of net debt to net capitalization was 39.7% at December 31, 2014, compared to 31.3% at December 31, 2013.

We define net debt as total debt, including current maturities, minus cash and cash equivalents.  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 can we take in addition to the use of the equity and 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 10 “Financing” for a discussion about the covenants requirements related to our long-term debt.

Capital investment programs

A discussion of our capital investment programs is an important part of understanding our liquidity and capital resources. We expect to meet the cash requirements for these capital expenditures 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.

CONTRACTUAL OBLIGATIONS

The following table summarizes our significant contractual obligations as of December 31, 2014:

(a)The above table does not include any future payment related to uncertain tax position liabilities because there is often a high degree of uncertainty regarding the timing of future cash outflows.  As of December 31, 2014 the liability recognized by the Company is $319.4 million and is included as non-current liability in the consolidated balance sheet.

86

Long-term debt payments do not include the debt discount valuation account of $45.1 million.

Interest on debt is calculated at rates in effect at December 31, 2014.  As all our debt is at fixed rates, future expenditures will not change due to rate changes.  Please refer to Note 10 “Financing” of our 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 following determination of final results for the year. Amounts in excess of 18 times a worker’s salary is 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.

Pension and post retirement obligations include the benefits expected to be paid under our pension and post-retirement benefit plans.  Please refer to Note 11 “Benefit Plans” of our consolidated financial statements.

Asset retirement obligations include the aggregate amount of the closure and remediation costs of 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 9 “Asset Retirement Obligation.”

We have a commitment to purchase power for our Peruvian operations from Enersur through April 2017. In June 2014, we signed a power purchase agreement for 120MW with the state company Electroperu S.A., which will supply energy for our Peruvian operations for twenty years starting on April 17, 2017 and ending on April 30, 2037. Also in July 2014, we signed a power purchase agreement for 120MW with a private power generator Kallpa, which will supply energy for our Peruvian operations for ten years starting on April 17, 2017 and ending on April 30, 2027.

Also 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 on the above table 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 expenditure projects include committed purchase orders and executed contracts principally for our Mexican projects at the Buenavista mine.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity price risk:

We are subject to market risks arising from the volatility of copper and other metal 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.

For 2015, assuming that expected metal production and sales are achieved, that tax rates are unchanged, giving no effects to potential hedging programs, metal price sensitivity factors would indicate the following change in estimated annual net income attributable to SCC resulting from metal price changes:

	Copper		Molybdenum		Zinc		Silver
Change in metal prices (per pound except silver — per ounce)	$	0.10	$	1.00	$	0.10	$	1.0
Annual change in net income attributable to SCC (in millions)	$	99.3	$	27.8	$	12.7	$	7.5

Open sales risk:

Our provisional copper and molybdenum sales contain an embedded derivative that is required to be separate from the host contract for accounting purposes. The host contract is the receivable from the sale of copper and molybdenum concentrates at prevailing market prices at the time of the sale. The embedded derivative, which does not qualify for hedge accounting, is marked to market through earnings each period prior to settlement.

Following are the provisionally priced copper and molybdenum sales outstanding at December 31, 2014:

	Sales volume(million lbs.)	Priced at(per pound)	Month of settlement
Copper	7.4	2.873	From January 2015 to April 2015
Molybdenum	11.7	9.00	From January 2015 to March 2015

Provisional sales price adjustments included in accounts receivable and net sales at December, 31, 2014 were $(9.6) million for copper and $(16.5) million for molybdenum

Foreign currency exchange rate risk:

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

	Years Ended December 31,
	2014		2013		2012
Peru:
Peruvian inflation rate	3.2	%	2.9	%	2.6	%
Initial exchange rate	2.796		2.551		2.697
Closing exchange rate	2.989		2.796		2.551
Appreciation/(devaluation)	(6.9	)%	(9.6	)%	5.4	%
Mexico:
Mexican inflation rate	4.1	%	4.0	%	3.6	%
Initial exchange rate	13.077		13.010		13.979
Closing exchange rate	14.718		13.077		13.010
Appreciation/(devaluation)	(12.6	)%	(0.5	)%	6.9	%

90

Change in monetary position:

Assuming an exchange rate variance of 10% at December 31, 2014, we estimate our net monetary position in Peruvian nuevo sol and Mexican peso would increase (decrease) our net earnings as follows:

	Effect in net earnings($ in millions)
Appreciation of 10% in U.S. dollar vs. nuevo sol	$	11.0
Devaluation of 10% in U.S. dollar vs. nuevo sol	$	(12.9	)
Appreciation of 10% in U.S. dollar vs. Mexican peso	$	23.5
Devaluation of 10% in U.S. dollar vs. Mexican peso	$	(28.8	)

The net monetary position is net of those assets and liabilities that are nuevo sol or peso denominated at December 31, 2014.

Short-term investments:

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

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:

We have audited the accompanying consolidated balance sheets of Southern Copper Corporation and subsidiaries (the “Company”) as of December 31, 2014 and 2013, and the related consolidated statements of earnings, comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2014.  Our audits also included the financial statement schedules listed in the Index at Item 15.  These financial statements and financial statement schedules are the responsibility of the Company’s management.  Our responsibility is to express an opinion on these financial statements and financial statement schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Southern Copper Corporation and subsidiaries as of December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America.  Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2015 expressed an adverse opinion on the Company’s internal control over financial reporting because of a material weakness.

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, 2014, Grupo Mexico through its wholly-owned subsidiary Americas Mining Corporation (“AMC”) owned 84.6% of the Company’s capital stock. The consolidated financial statements presented herein consist of the accounts of Southern Copper Corporation (“SCC” or the “Company”), a Delaware corporation, and its subsidiaries. The Company is an integrated producer of copper and other minerals, and operates mining, smelting and refining facilities in Peru and Mexico. The Company conducts its primary operations in Peru through a registered branch (the “Peruvian Branch” or “Branch” or “SPCC Peru Branch”). The Peruvian Branch is not a corporation separate from the Company. The Company’s Mexican operations are conducted through subsidiaries. The Company also conducts exploration activities in Argentina, Chile, Ecuador, Mexico and Peru.

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 810 Consolidation. Such financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Certain prior year amounts have been reclassified to conform to the current year presentation.

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—

Substantially all of the Company’s copper and non-copper products are sold under annual or other longer-term contracts.

Revenue is recognized when title passes to the customer. The passing of title is based on terms of the contract, generally upon shipment. Copper and non-copper revenues are determined 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.

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.

99

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.

Shipping and handling fees and costs—

Amounts billed to customers for shipping and handling are classified as sales. Amounts incurred for shipping and handling are included in cost of sales (exclusive of depreciation, amortization and depletion).

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 market. 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 market less a reserve for obsolescence.

Long-term inventory - Leachable material

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. 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 on its balance sheet current leach inventory (included in work-in-process inventories) and long-term leach inventory. Through 2013, the cost attributed to the leach material was charged to cost of sales over a five-year period, which was considered the average estimated recovery period based on the historical recovery percentages of each mine. During the fourth quarter of 2014, the Company completed the construction of a new plant that has resulted in increased efficiency in production and use of leachable material.  Accordingly, the Company changed its method of amortization to the units of production method.  This change in estimate effected by a change in accounting principle will result in a better matching of costs to revenues as a result of the improved production levels expected from the new plant and will

100

result in a better estimate of current and long-term leachable material inventory  As the plant entered into operation in the fourth quarter of 2014, the impact to results in 2014 was not considered significant and totaled approximately $17 million recognized within cost of sales. . The Company anticipates that the impact in future periods will be significant as a result of expected increased production levels.

As of December 31, 2014 the Company has leachable inventory of $762.8 million of which $250.1 million was classified as a current asset.

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 five to 40 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.

There is a diversity of practices in the mining industry in 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, 2014, 2013 and 2012, the Company did not capitalize any drilling and related costs. The net balance of capitalized mine development costs at December 31, 2014 and 2013, were $34.8 million and $36.2 million, respectively.

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

101

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, which are included in other assets, are amortized using the effective interest method over the term of the related debt.

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 $3.36, $3.65 and $3.68 at the end of 2014, 2013 and 2012, 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 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 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. Deferred income tax assets are reduced by any benefits that, in the opinion of management, are more likely not to be realized. ASU No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” was effective for the Company’s fiscal year beginning January 1, 2014.  As a result of the adoption of ASU No. 2013-11 on January 1, 2014, liabilities associated with Unrecognized Tax Benefits of Non-Current Tax Payable were reclassified to net against deferred income tax assets.  In accordance with ASU 2013-11, the Company netted Unrecognized Tax Benefits against the foreign tax credit carryforward.

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 taxing 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

102

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 nuevos soles and Mexican pesos, respectively.

Foreign currency assets and liabilities are remeasured into U.S. dollars at current 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. The results of its impairment tests using these long-term copper and molybdenum prices show no 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, 2014, 2013 and 2012, the components of “other comprehensive income (loss)” were the unrealized gain (loss) on cash flow hedge derivative instruments, the unrecognized gain (loss) on employee benefit obligations and realized gain (loss) included in net income.

Business segments-

Company management views Southern Copper as having three 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 two 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 five underground mines that produce zinc, copper, silver and gold, a coal mine and a zinc refinery. Please see Note 18 “Segments and Related Information.”

Senior Management Officers of the Company focus on operating income as measure 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.

PROPOSED ACCOUNTING STANDARDS

In February 2013, the Financial Accounting Standards Board (FASB) issued the Accounting Standard Updates (“ASU”)  2013-04, “Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for which the Total Amount of the Obligation is Fixed at the Reporting Date.” The amendments in this ASU require an entity to measure joint and several

103

obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The amendments in this guidance are effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. The Company will apply this guidance in any future arrangement and does not expect this guidance to have a material impact on its consolidated financial information.

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

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

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

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

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

Step 3: Determine the transaction price.

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

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

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

This revenue standard is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted. The Company does not expect this guidance to have a material impact on the consolidated financial information.

The reconciliation of the statutory income tax rate to the effective tax rate is as follows (in percentage points):

	For the years ended December 31,
	2014		2013		2012
Expected tax at U.S. statutory rate	35.0	%	35.0	%	35.0	%
Foreign tax at other than statutory rate, net of foreign tax credit benefit	(0.9	)	(0.2	)	(0.5	)

Other	0.7		0.1		(0.4	)
Effective income tax rate	36.5	%	32.4	%	36.3	%

The Company files income tax returns in three jurisdictions, Peru, Mexico and the United States. For the three years presented above, the statutory income tax rates for Peru and Mexico were 30% and 35% for the United States. While the largest components of income taxes are the Peruvian and Mexican taxes, the Company is a domestic U.S. entity. Therefore, the rate used in the above reconciliation is the U.S. statutory rate.

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. Some permanent differences relate specifically to SCC such as the allowance in the United States for percentage depletion. SCC’s taxable income for the fiscal years 2012 through 2014, was, or will be, included in the U.S. federal income tax return of AMC, its parent company; see U.S. tax matters, below. For financial reporting and presentation purposes SCC is providing current and deferred income taxes, as if it remains a separate U.S. tax filer apart from AMC.

Deferred taxes include the U.S., Peruvian and Mexican tax effects of the following types of temporary differences and carryforwards:

	As of December 31,
(in millions)	2014			2013
Assets:
Inventories	$	32.5		$	18.7

107

U.S. Tax Matters—

In September 2013 the Internal Revenue Service (“IRS”) issued the final Tangible Property Regulations. These regulations are effective January 1, 2014 with some elective retroactive application available. These regulations look to provide a framework for distinguishing capital expenditures from deductible business expenses and they attempt to find the middle ground where taxpayers and the IRS often disagreed. The Company has reviewed these regulations and has concluded that they should not have a material effect on its financial statements.

As of December 31, 2014, the Company considers its ownership of the stock of Minera Mexico to be essentially permanent in duration. The excess of the amount for financial reporting over the tax basis of the investment in this stock is estimated to be at least $5.3 billion.

As of December 31, 2014, $37.7 million of the Company’s cash, cash equivalents, restricted cash and short-term investments of $722.0 million was held by foreign subsidiaries. The cash, cash equivalents and short-term investments maintained in the Company’s foreign operations are generally used to cover local operating and investment expenses. The Company had provided a deferred tax liability of $7.4 million as of December 31, 2013 for the U.S. income tax effects of $76.2 million of foreign earnings that may potentially be repatriated in the future.  At December 31, 2014 Minera Mexico has determined that it has no remittable earnings available for dividends to the United States due to its internal financial obligations and current expansion, and that at the end of 2014 it has met the indefinite reversal criteria of ASC 740-30-25-17 that it intends to reinvest its earnings indefinitely. Any distribution of earning from the Company’s Mexican subsidiaries to the United States is subject to a U.S. federal income tax that equates to approximately 10% of the amount of the distribution, after considering foreign tax credit utilization. Distributions of earnings from the Company’s Peruvian branch to the United States are not subject to repatriation taxes. The Company’s Peruvian operations are not foreign subsidiaries. Rather they are mainly comprised of operations that are treated as a branch of the Company’s U.S. operations from a tax perspective.

At December 31, 2014, there were $447.0 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 no other unused U.S. tax credits at December 31, 2014. These credits can expire as follows:

Year	Amount
2016	$	19.0
2018	20.4
2019	63.7
2020	42.0
2021	11.7
2022	84.1
2023	69.2
2024	136.9
Total	$	447.0

These foreign tax credits are presented above on a gross basis and have not been reduced here for any unrecognized tax benefits. ASU No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” is effective prospectively for the Company’s fiscal year beginning January 1, 2014. In accordance with ASU 2013-11 The Company has recorded $302.2 million of an unrecognized tax benefit as an offset to our deferred tax asset for foreign tax credits.  The remaining foreign tax credits of $144.8 million will be used to offset future liabilities but can expire if not utilized by 2023 ($7.9M) and 2024 ($136.9M).

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 income tax return.

108

Peruvian Tax Matters-

The Company obtains income tax credits in Peru for value-added taxes paid in connection with the purchase of goods and services employed in its operations and capital equipment and records these credits as a prepaid expense. Under current Peruvian law, the Company is entitled to use the credits against its Peruvian income tax liability or to receive a refund. The carrying value of these Peruvian tax credits approximates their net realizable value.

Royalty mining charge: In 2011, the Peruvian congress approved an amendment to the mining royalty charge. The mining royalty charge is based on operating income margins with graduated rates ranging from 1% to 12% of operating profits, with a minimum royalty charge assessed at 1% of net sales. If the operating income margin is 10% or less, the royalty charge is 1% and for each 5% increment in the operating income margin, the royalty charge rate increases by 0.75%, up to a maximum of 12%. For 2014 hereinafter, the minimum royalty charge assessed at 1% of net sales is recorded as cost of sales and those amounts assessed against operating income are included in the income tax provision. The Company has accrued $32.4 million, $34.8 million and $51.0 million of royalty charge in 2014, 2013 and 2012, respectively, of which $7.5 million was included in income taxes in 2014.

Special Mining tax: In 2011, the Peruvian government enacted a tax for the mining industry. This tax is based on operating income and its rate ranges from 2% to 8.4%. It begins at 2% for operating income margin up to 10% and increases by 0.4% of operating income for each additional 5% of operating income until 85% of operating income is reached. The Company made provision for this tax of $35.3 million, $25.5 million and $49.6 million in 2014, 2013 and 2012, respectively. These provisions are included as “income taxes” in the consolidated statement of earnings.

As of December 31, 2014, the income tax rate was 30% and the dividend tax rate was 4.1%. In the last quarter of 2014, the Peruvian congress enacted tax law changes to both the income tax and dividend tax rates that become effective on January 1, 2015. The new rates are as follows:

Year	IncomeTax Rate		DividendTax Rate
2015- 2016	28	%	6.8	%
2017- 2018	27	%	8.0	%
2019 and later	26	%	9.3	%

The recalculation of the deferred tax liability for the Peruvian jurisdiction using the new tax rates did not have a material effect on the deferred tax liability or the financial statements of the Company.

Mexican Tax Matters-

In 2013, the Mexican Congress enacted tax law changes that became effective on January 1, 2014. Among others, this new law establishes:

·A mining royalty at the rate of 7.5% on taxable Earnings Before Taxes adjusted as defined by Mexican tax regulations; that had a net after tax cost of $79.3  million.

·An additional royalty of 0.5% over gross income from sales of gold, silver and platinum;

·The replacement of the consolidation tax regime that creates a more restrictive tax consolidation regimen;

·A 10% withholding on dividends distributed to Mexican individuals or foreign residents (individuals or corporations) and applies to net income generated after 2013;

·A new environmental tax on the sale and importation of fossil fuels that had an annual estimated cost of approximately $9.4  million, and was included in cost of fuel

·Limits (at 47 or 53%) deductions for tax-exempt salaries as well as for contributions to pension plans;

·The requirement to maintain the Mexican statutory income tax rate at 30% thereby eliminating the scheduled reductions for 2014 and 2015; and

·The elimination of the flat tax.

Related to these tax changes, in 2013 the Company recognized a deferred income tax provision of $34.7 million.

109

Accounting for Uncertainty in Income Taxes-

The total amount of unrecognized tax benefits in 2014, 2013 and 2012, was as follows (in millions):

	2014		2013		2012
Unrecognized tax benefits, opening balance	$	221.2	$	221.2	$	70.6
Gross increases — tax positions in prior period	55.1		—		39.7
Gross decreases — tax positions in prior period	—		—		0.2
Gross increases — current-period tax positions	43.1		—		110.7
	98.2		—		150.6
Unrecognized tax benefits, ending balance	$	319.4	$	221.2	$	221.2

The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $319.4 million and $221.2 million at December 31, 2014 and 2013, respectively. These amounts relate entirely to U.S. income tax matters. The Company has no unrecognized Peruvian or Mexican tax benefits.

As of December 31, 2014 and 2013, the Company’s liability for uncertain tax positions included no amount for accrued interest and penalties due to the excess foreign tax credits.

The following tax years remain open to examination and adjustment in the Company’s three major tax jurisdictions:

Peru:	2011 up to 2014 (years 2011 and 2012 are being examined in 2015)
U.S.:	2008 and all subsequent years
Mexico:	2010 and all subsequent years

Management does not expect that any of the open years will result in a cash payment within the upcoming twelve months ending December 31, 2015.  The Company’s reasonable expectations about future resolutions of uncertain items did not materially change during the year ended December 31, 2014.

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 $2.8 million in 2014). 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. In December 2013, the Mexican Congress approved some amendments to the tax law, as consequence the Company recorded a deferred workers’ participation provision of $16.3 million.

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, 2014 was as follows (in millions):

	2014			2013		2012
Current	$	221.2		$	201.6	$	263.1

NOTE 9-ASSET RETIREMENT OBLIGATION:

The Company maintains an estimated asset retirement obligation for its mining properties in Peru, as required by the Peruvian Mine Closure Law.  In accordance with the requirements of this law, the Company’s closure plans were approved by the Peruvian Ministry of Energy and Mines (“MINEM”). As part of the closure plans, 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 reviews of closing plans every five years. Currently and for the near-term future, the Company has pledged the value of its Lima office complex as support for this obligation. The accepted value of the Lima office building for this purpose is $27.8 million. Through December 2014, the Company has provided guarantees of $17.9 million. The closure cost recognized for this liability includes the cost, as outlined in its closure plans, of dismantling the Toquepala and Cuajone concentrators, the smelter and refinery in Ilo, and the shops and auxiliary facilities at the three units. In 2014, the Company reviewed ASC 410-20 Asset Retirement Obligation rule  and adjusted the liability by $36.3 million at its Peruvian operations. A comparable adjustment was applied against the deferred asset recognized in property.  The net effect of these adjustments did not change the Company’s net income.

In 2010, the Company communicated to the Mexican federal environmental authorities its closure plans for the copper smelter plant at San Luis Potosi. The Company initiated a program for plant demolition and soil remediation. In January 2014, the Company approved an increase in the budget for this program to $62.4 million, of which the Company has spent $46.9 million through December 31, 2014. Plant demolition and construction of a confinement area at the south of the property were completed in 2012 and the Company expects to complete soil remediation and the construction of a second confinement area during the second quarter of 2015. The Company expects that once the site is remediated, a decision will be made on whether sell or develop the property.

In 2012, the Company recognized an estimated asset retirement obligation for its mining properties in Mexico as part of its environmental commitment. Even though there is currently no enacted law, statute, ordinance, written or oral contract requiring the Company to carry out mine closure and environmental remediation activities, the Company believes that a constructive obligation presently exists based on, among other things, the remediation caused by the closure of the San Luis Potosi smelter in 2010. Consequently, according to ASC- 410-20 on December 31, 2012 the Company recorded an asset retirement obligation of $25.1 million and increased net property by $20.3 million. The overall cost recognized for mining closure includes the estimated costs of dismantling concentrators, smelter and refinery plants, shops and other facilities.

The following table summarizes the asset retirement obligation activity for years ended December 31, 2014 and 2013 (in millions):

111

The difference between the face amount and the balance as of December 31, 2014 and 2013 of the senior unsecured notes is the unamortized issuance discount, which is being amortized over the term of the related debt.

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, 2014, Minera Mexico was in compliance with this covenant.

Between July 2005 and November 2012 the Company issued senior unsecured notes six 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.

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.

Related to these notes, the Company capitalized $28.9 million of issuance costs which unamortized balance is included in “Other assets,” non-current on the consolidated balance sheet and are being amortized as interest expense over the life of the loans. At December 31, 2014 and 2013, the balance of capitalized debt issuance costs was $25.2 million and $26.1 million, respectively. Amortization charged to interest expense was $0.9 million, $0.8 million and $0.6 million in 2014, 2013 and 2012, respectively.

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 one or more gradations.

At December 31, 2014, the Company was in compliance with the covenants of the notes.

Aggregate maturities of the outstanding borrowings at December 31, 2014, are as follows:

Years	Principal Due (*)
	(in millions)
2015	$	200.0
2016	—

(*)Total debt maturities do not include the debt discount valuation account of $45.2 million.

NOTE 11-BENEFIT PLANS:

Post retirement defined benefit plan:

The Company has two noncontributory defined benefit pension plans covering former salaried employees in the United States and certain former expatriate employees in Peru (the “Expatriate Plan”). Effective October 31, 2000, the Board of Directors amended the qualified pension plan to suspend the accrual of benefits.

In October 2014, the Society of Actuaries (SOA) issued new mortality tables based on a comprehensive study of private retirement plans. Effective December 31, 2014, the Company elected to update the mortality assumption to the new SOA tables.

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

The components of net periodic benefit costs calculated in accordance with ASC 715 “Compensation retirement benefits,” using December 31 as a measurement date, consist of the following:

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.

114

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 “Money Fund”) and the MetLife Broad Market Bond Fund (the “Bond Fund”) managed by BlackRock, Inc.

The Money Fund seeks to earn interest and maintain a $1.00 per share net asset value, by investing in U.S. Dollar-denominated money market securities.

The Bond Fund seeks to outperform the 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.

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 4.50% 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 three financial institutions, Scotiabank Inverlat S.A., Banco Santander and IXE Banco, S.A. 27% of the funds are invested in Mexican government securities, including treasury certificates and development bonds of the Mexican government. The remaining 73% 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 30% of benefit obligations. The following table represents the asset mix of the investment portfolio as of December 31:

	2014		2013
Asset category:
Equity securities	73	%	74	%
Treasury bills	27	%	26	%
	100	%	100	%

The amount of contributions that the Company expects to pay to the plan during 2015 is $6.3 million, which includes $3.4 million of pending payments to former Buenavista workers.

Post-retirement Health Care Plan

Peru: The Company adopted a post-retirement health care plan for retired salaried employees eligible for Medicare in 1996. The Company manages the plan and is currently providing health benefits to retirees. The plan is accounted for in accordance with ASC 715 “Compensation retirement benefits.”

Mexico: Through 2007, the Buenavista unit provided health care services free of charge to employees and retired unionized employees and their families through its own hospital at the Buenavista unit.  In 2011, 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 del Cobre will receive health services from the Mexican Institute of Social Security as is the case for all Mexican workers.

Expatriate Health Plan

For measurement purposes, a 5.8% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2014. The rate is assumed to decrease gradually to 4.6%.

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 4.0% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2014 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:

	One Percentage Point
(in millions)	Increase		Decrease
Effect on total service and interest cost components	$	1.3	$	0.8
Effect on the post-retirement benefit obligation	$	17.2	$	13.7

NOTE 12-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, formerly named labor 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 balance sheet are the still 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 13-COMMITMENTS AND CONTINGENCIES:

Environmental matters:

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

Environmental capital expenditures in years 2014, 2013 and 2012, were as follows (in millions):

	2014		2013		2012
Peruvian operations	$	127.0	$	76.9	$	27.0
Mexican operations	24.4		39.8		20.7
Total	$	151.4	$	116.7	$	47.7

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 closure and reclamation. In accordance with the requirements of this law, the Company’s closure plans were approved by MINEM. As part of the closure plans, the Company is providing guarantees to ensure that sufficient funds will be available for the asset retirement obligation. See Note 9 “Asset retirement obligation,” for further discussion of this matter.

In 2008, the Peruvian government enacted environmental regulations establishing more stringent air quality standards (“AQS”) for daily sulfur dioxide (“SO2”) emissions for the Peruvian territory. These regulations, as amended in 2013, recognize distinct zones/areas, as atmospheric basins. As part of these regulations, MINAM was required to carry-out a 12 month ambient air monitoring period, prior to January 1, 2014, to establish SO2 levels. Those areas with a mean 24-hour SO2 concentration equal or less than 20 micrograms per cubic meter (“ug/m3”) are required to develop programs to maintain this level of compliance. Those areas or cities exceeding the mean 24-hour SO2 concentration of 20 ug/m3 will be required to establish an action plan to address this problem and are required to achieve the 20 ug/m3 AQS in the future. Meanwhile they are required to achieve mean 24-hour AQS equal to 80 ug/m3 of SO2. MINAM has established three atmospheric basins that require further attention to comply with 80ug/m3 of SO2. The Ilo basin is one of these three areas and the Company’s smelter and refinery are part of the area. A supreme decree issued on April 8, 2014, indicates that the Company should review its compliance with these regulations and develop a modification plan to reach compliance. The

118

Company is working with an environmental technical study group, established by a MINAM resolution to identify air quality issues and develop plans to comply with the pertinent regulations.

In 2013, the Peruvian government enacted new soil environmental quality standards (“SQS”) applicable to any existing facility or project that generates or could generate risk of soil contamination in its area of operation or influence. In March 2014, MINAM issued a supreme decree which establishes additional provisions for the gradual implementation of SQS. Under this rule the Company has twelve months to identify contaminated sites in and around its facilities and present a report of identified contaminated sites. If such sites exist, the Company must submit a decontamination plan for approval within 24 months from the date it is notified by the authority. This decontamination plan shall include remediation actions, a schedule and compliance deadlines. Also, under this rule, if deemed necessary, the Company may request a one year extension, given sound justification. Soil confirmation tests must be carried out after completion of decontamination actions (within the approved schedule) and results must be presented to the authorities within 30 days after receiving such results. Non-compliance with this obligation or with decontamination goals will carry penalties, although no specific sanctions have been established yet. During compliance schedule, companies cannot be penalized for non-compliance with the SQS. In the fourth quarter of 2014, the Company selected the consultant to carry out soil samplings, studies and other requirements of the rules.

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. PROFEPA may initiate administrative proceedings against companies that violate environmental laws, which in the most extreme cases may result in the temporary or permanent closing of non-complying facilities, the revocation of operating licenses and/or other sanctions or fines. Also, according to the federal criminal code, PROFEPA must inform corresponding authorities regarding environmental non-compliance.

In January 2011, Article 180 of the General Law was amended. This amendment, gives an individual or entity the ability to contest administrative acts, including environmental authorizations, permits or concessions granted, without the need to demonstrate the actual existence of harm to the environment, natural resources, flora, fauna or human health, because it will be sufficient to argue that the harm may be caused. In addition, in 2011, amendments to the Civil Federal Procedures Code (“CFPC”) were published in the Official Gazette and are now in force. These amendments establish three categories of collective actions by means of which 30 or more people claiming injury derived from environmental, consumer protection, financial services and economic competition issues will be considered to be sufficient in order to have a legitimate interest to seek through a civil procedure restitution or economic compensation or suspension of the activities from which the alleged injury derived. The amendments to the CFPC may result in more litigation, with plaintiffs seeking remedies, including suspension of the activities alleged to cause harm.

In June 2013, the Environmental Liability Federal Law was published in the Official Gazette and became effective one month thereafter. The law establishes general guidelines in order to determine which environmental actions will be considered to cause environmental harm that will give rise to administrative responsibilities (remediation or compensations), criminal responsibilities as well as monetary fines.

On August 6, 2014, an accidental spill of approximately 40,000 cubic meters of copper sulfate solution occurred at a leaching pond that was under construction ten kilometers away from the mine of Buenavista del Cobre, S.A. de C.V. (“BVC”) a subsidiary of the Company. The accident was caused by a rock collapse that affected the system’s pumping station and by a construction defect in the seal of a pipe in the leaching system containment dam, a part of the new SX-EW III plant. This solution reached the Bacanuchi River, a branch of the Sonora River. All the immediate actions were properly taken in order to contain the spill, and to comply with all the legal requirements.

On August 19, 2014, PROFEPA, as part of the administrative proceeding initiated after the spill, announced the filing of a criminal complaint against BVC and those determined to be responsible for the environmental damages. The criminal complaint filed by PROFEPA against BVC is in the procedural stages. The Company is vigorously defending against it. According to the Mexican Environmental Responsibilities Federal Law, administrative fines and sanctions could go upward to 40 million Mexican pesos (approximately $3 million). Additional sanctions or fines may be imposed, including the cost of cleanup and remediation of the

119

polluted sites, as well as economic compensation to individuals who may have suffered damages as a result of the spill, provided that direct damages are proven.

On September 15, 2014, BVC, in agreement with the Mexican Federal Government, established a trust of up to two billion pesos (approximately $150 million) to support the remedial efforts that BVC had already undertaken, to comply with the environmental remediation plan and to pay, as the case may be, material damages to the riverside residents of the seven counties affected by the spill. In 2014, BVC estimated the contingent liability at $91.4 million, of which $16.4 million had been paid previous to the establishment of the trust, and approximately one billion pesos (approximately $74.9 million) was deposited in the trust. These funds have been available and have been used to compensate claims as they have arisen. This deposit was classified as restricted cash and was recorded as an operating expense in the 2014 results. A technical committee was created to manage the funds, comprised of representatives from the federal government, the Company and specialists assisted by a team of environmental experts. The trust established by the Company and the administrative agreement executed with the corresponding Federal authorities, serves as an alternative mechanism for dispute resolution to mitigate public and private litigation risks.

On November 27, 2014, a remediation program was presented before SEMARNAT, the federal agency of environment and natural resources, which was approved on January 6, 2015.

On December 31, 2014, PROFEPA initiated an administrative proceeding directly derived from the spill, which is still in its initial stages. The National Commission for Water (“CONAGUA”), and the Federal Commission for the Protection against Sanitary Risks (“COFEPRIS”), have initiated certain proceedings, not directly linked to the spill, to monitor Company’s compliance with the applicable environmental laws.  In addition, the Company has been served with three collective action lawsuits seeking damages for injuries related to the spill, which are in an early procedural stages. For a description of collective actions in Mexico refer to the 2011 amendments to the CFPC described above. The Company asserts that these lawsuits are without merit and is vigorously defending against them.

The Company reasonably considers that none of the legal proceedings resulting from the spill, individually or in the aggregate, would have a material effect on its financial position or results of operations.

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

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

Litigation matters:

Garcia Ataucuri and Others against SCC’s Peruvian Branch:

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

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

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

1)Mr. Garcia Ataucuri seeks delivery, to himself and each of the approximately 900 former employees of the Peruvian Branch, of the 3,876,380,679.65 old soles or 38,763,806.80 “labor shares” (acciones laborales), as required by Decree Law 22333 (a former profit sharing law), to be issued proportionally to each former employee in accordance with the time of employment of

120

such employee with SCC’s Branch in Peru, plus dividends on such shares. The 38,763,806.80 labor shares sought in the complaint, with a face value of 100.00 old soles each, represent 100% of the labor shares issued by the Branch during the 1970s until 1979 for all of its employees during that period. The plaintiffs do not represent 100% of the Branch´s eligible employees during that period.

It should be noted that the lawsuit refers to a prior Peruvian currency called “sol de oro” or old soles, which was later changed to the “inti”, and then into today´s “nuevo sol.” Due to a past period of high inflation between 1985 and 1990, one billion of old soles is equivalent to today’s one nuevo sol.

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

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

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

On June 9, 2009, SCC’s Peruvian Branch filed a proceeding of relief before a civil court in Peru seeking the nullity of the 2009 Supreme Court decision and, in a separate proceeding, a request for a precautionary measure. The civil court rendered a favorable decision on the nullity and the precautionary measure, suspending the enforcement of the Supreme Court decision, for the reasons indicated above and other reasons. In February 2012, the Branch was notified that the civil court had reversed its prior decisions. On appeal by the Peruvian Branch the Superior Court affirmed the lower court’s decisions regarding the nullity of the 2009 Supreme Court decision and the precautionary measure.  As a result, the nullity of the precautionary measure became final and is not appealable. However, the nullity of the 2009 Supreme Court decision was appealed by the Branch before the Constitutional Court. On April 10, 2014, the Constitutional Court denied the Company’s appeal and affirmed the lower court’s decision.  In view of this, SCC’s Peruvian Branch continues to analyze the manner in which the competent lower court will enforce the Supreme Court’s decision and its financial impact.

2)In addition, there are filed against SCC’s Branch the following lawsuits, involving approximately 800 plaintiffs, which seek the same number of labor shares as in the Garcia Ataucuri case, plus interest, labor shares resulting from capital increases and dividends: Armando Cornejo Flores and others v. SCC’s Peruvian Branch (filed May 10, 2006); Alejandro Zapata Mamani and others v. SCC’s Peruvian Branch (filed June 27, 2008); Edgardo Garcia Ataucuri, in representation of 216 of SCC’s Peruvian Branch former workers, v. SCC’s Peruvian Branch (filed May 2011); Juan Guillermo Oporto Carpio v. SCC’s Peruvian Branch (filed August 2011); Rene Mercado Caballero v. SCC’s Peruvian Branch (filed November 2011); Enrique Salazar Alvarez and others v. SCC’s Peruvian Branch (filed December 2011); Jesus Mamani Chura and others v. SCC’s Peruvian Branch (filed March 2012); Armando Cornejo Flores, in representation of 37 of SCC’s Peruvian Branch former workers v. SCC’s Peruvian Branch (filed March 2012), Porfirio Ochochoque Mamani and others v. SCC’s Peruvian Branch (filed July 2012); Alfonso Claudio Flores Jimenez and others v. SCC’s Peruvian Branch (filed July 2013) and Micaela Laura Alvarez de Vargas and others v. SCC’s Peruvian Branch (filed August 2013). SCC’s Peruvian Branch has answered the complaints and denied the validity of the claims.

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

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

121

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

Related to the “Virgen Maria” mining concessions, the Company is party to the following lawsuits:

a)Exploraciones de Concesiones Metalicas S.A.C. (“Excomet”): In August 2009, a lawsuit was filed against SCC’s Branch by the former stockholders of Excomet.  The plaintiffs allege that the acquisition of Excomet’s shares by the Branch is null and void because the $2 million purchase price paid by the Branch for the shares of Excomet was not fairly negotiated by the plaintiffs and the Branch.  In 2005, the Branch acquired the shares of Excomet after lengthy negotiations with the plaintiffs, and after the plaintiffs, which were all the stockholders of Excomet, approved the transaction in a general stockholders’ meeting.  Excomet was at the time owner of the “Virgen Maria” mining concession.  In October 2011, the civil court dismissed the case on the grounds that the claim had been barred by the statute of limitations.  On appeal by the plaintiffs, the superior court reversed the lower court’s decision and remanded it to the lower court for further proceedings.  As of December 31, 2014, the case remains pending resolution without further developments.

b)Sociedad Minera de Responsabilidad Limitada Virgen Maria de Arequipa (SMRL Virgen Maria): In August 2010, a lawsuit was filed against SCC’s Branch and others by SMRL Virgen Maria, a company which until July 2003 owned the mining concession Virgen Maria.  SMRL Virgen Maria sold this mining concession in July 2003 to Excomet (see a) above).  The plaintiff alleges that the sale of the mining concession Virgen Maria to Excomet is null and void because the persons who attended the shareholders’ meeting of SMRL Virgen Maria, at which the purchase was agreed upon, were not the real owners of the shares.  The plaintiff is also pursuing the nullity of all the subsequent acts regarding the mining property (acquisition of the shares of Excomet by SCC’s Branch, noted above, and the sale of this concession to SCC’s Branch by Excomet). In October 2011, the civil court dismissed the case on the grounds that the claim had been barred by the statute of limitations.  Upon appeal by the plaintiffs, the superior court remanded the proceedings to the lower court, ordering the issuance of a new decision.  On June 25, 2013, the lower court dismissed the case due to procedural defects. Upon appeal by the plaintiff, on December 2, 2013, the Superior Court reversed the lower court’s decision due to procedural defects and ordered the issuance of a new resolution. In July 2014, once again the lower court dismissed the case on the grounds that the claim had barred by the statute of limitations. The plaintiff appealed this resolution before the Superior Court. As of December 31, 2014, the case remains pending resolution without further developments.

c)Omar Nunez Melgar: In May 2011, Mr. Omar Nunez Melgar commenced a lawsuit against the Peruvian Mining and Metallurgical Institute and MINEM challenging the denial of his request of a new mining concession that conflicted with SCC’s Branch’s Virgen Maria mining concession.  SCC’s Branch has been made a party to the proceedings as the owner of the Virgen Maria concession.  SCC’s Branch has answered the complaint and denied the validity of the claim.  As of December 31, 2014, the case remains pending resolution without further developments.

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

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

In the last quarter of 2012, the Pasto Grande Project, an entity of the Regional Government of Moquegua, filed a lawsuit against SCC’s Peruvian Branch alleging property rights over a certain area used by the Peruvian Branch and seeking the demolition of the tailings dam where SCC’s Peruvian Branch has deposited its tailings from the Toquepala and Cuajone operations since 1995.  The Peruvian Branch has had title to use the area in question since 1960 and has constructed and operated the tailing dams also with proper governmental authorization, since 1995.  SCC’s Peruvian Branch asserts that the lawsuit is without merit and is vigorously defending against the lawsuit. Upon a motion filed by the Peruvian Branch, the lower court has included the MINEM as a defendant in this lawsuit.  MINEM has answered the complaint and denied the validity of the claim. As of December 31, 2014, the case remains pending resolution without further developments.

Labor matters:

Peruvian operations: Approximately 69% of the Company’s 4,524 Peruvian employees were unionized at December 31, 2014. There are seven separate unions, three of them at each major production area that represent the majority of the Company´s workers; and four smaller unions that represent the balance of workers. The Company conducted negotiations with the unions whose collective bargaining agreements expired in 2012. In 2013, the Company signed three-year agreements with all the unions. The agreements included, among other things, annual salary increases of 6.5%, 5% and 5% for each of the three years.

122

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

However, the workers of the San Martin and Taxco mines, who are still under the National Mining Union, have been on strike since July 2007. On December 10, 2009, a federal court confirmed the legality of the San Martin strike. In order to recover the control of the San Martin mine and resume operations, the Company filed a court petition on January 27, 2011 requesting that the court, among other things, define the termination payment for each unionized worker. The court denied the petition alleging that, according to federal labor law, the union was the only legitimate party to file such petition. On appeal by the Company, on May 13, 2011, the Mexican federal tribunal accepted the petition. In July 2011, the National Mining Union appealed the favorable court decision before the Supreme Court. On November 7, 2012, the Supreme Court affirmed the decision of the federal tribunal. The Company filed a new proceeding before the labor court on the basis of the Supreme Court decision, which recognized the right of the labor court to define responsibility for the strike and the termination payment for each unionized worker. A favorable decision of the labor court in this new proceeding would have the effect of terminating the protracted strike at San Martin. As of December 31, 2014, the case remains pending resolution without further developments.

In the case of the Taxco mine, following the workers refusal to allow exploration of new reserves, the Company commenced litigation seeking to terminate the labor relationship with workers of the Taxco mine (including the related collective bargaining agreement). On September 1, 2010, the federal labor court issued a ruling approving the termination of the collective bargaining agreement and all the individual labor contracts of the workers affiliated with the Mexican mining union at the Taxco mine. The mining union appealed the labor court ruling before a federal court. In September 2011, the federal court accepted the union’s appeal and requested that the federal labor court review the procedure. After several legal proceedings on January 25, 2013, the Company filed a new proceeding before the labor court. On June 16, 2014, the labor court denied the petition of the Company. The resolution issued by the labor court was challenged by the Company before a federal court. Considering the above decision of the Supreme Court, there could be grounds for a favorable decision to end the protracted strike at the Taxco Unit. As of December 31, 2014, the resolution of this case remains pending.

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

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

Other legal matters:

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

2007 Plan: In January 2007, the Company offered to eligible employees a stock purchase plan (the “Employee Stock Purchase Plan”) through a trust that acquires shares of Grupo Mexico stock for sale to its employees, employees of subsidiaries and certain affiliated companies.  The purchase price is established at the approximate fair market value on the grant date.  Every two years employees will be able to acquire title to 50% of the shares paid 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 one share for every ten shares purchased by the employee.

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

In the case of voluntary or involuntary resignation/termination of the employee, the Company will pay to the employee the fair market sales price at the date of resignation/termination of the fully paid shares, net of costs and taxes.  When the fair market sales value of the shares 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.

The stock based compensation expense for the years ended December 31, 2014, 2013 and 2012 and the remaining balance of the unrecognized compensation expense under the Employee Stock Purchase Plan, were as follows:

	2014		2013		2012

2010 Plan: During 2010, the Company offered to eligible employees a new stock purchase plan (the “New Employee Stock Purchase Plan”) through a trust that acquires series B shares of Grupo Mexico stock for sale to its employees, employees of subsidiaries, and certain affiliated companies. The purchase price was established at 26.51 Mexican pesos (approximately $2.05) for the initial subscription.  The terms of the New Employee Stock Purchase Plan are similar to the terms of the Employee Stock Purchase Plan.

The stock based compensation expense for the years ended December 31, 2014, 2013 and 2012 and the remaining balance of the unrecognized compensation expense under the New Employee Stock Purchase Plan, were as follows:

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.

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, 2014 (in millions):

	Balance at December 31, 2014
	Carrying Value		Fair Value
Liabilities:
Long-term debt	$	4,206.0	$	4,369.6

Long-term debt is carried at amortized cost and its estimated fair value is based on quoted market prices classified as Level 1 in the fair value hierarchy except for the case of the Yankee bonds and the 6.375% senior unsecured notes due date July 2015 which qualify as Level 2 in the fair value hierarchy as they are based on quoted priced in market that are not active.

128

Fair values of assets and liabilities measured at fair value on a recurring basis were calculated as of December 31, 2014 and 2013, as follows (in millions):

Fair Value at Measurement Date Using:

Molybdenum	100.2		100.2		—		—
Total	$	362.4	$	356.7	$	5.7	$	—

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 16-CONCENTRATION OF RISK:

The Company operates four open-pit copper mines, five underground poly-metallic mines, two smelters and eight refineries in Peru and Mexico and substantially all of its assets are located in these countries. There can be no assurances that the Company’s operations and assets that are subject to the jurisdiction of the governments of Peru and Mexico will not be adversely affected by future actions of such governments. Much of the Company’s products are exported from Peru and Mexico to customers principally in the United States, Europe, Asia and South America.

Financial instruments, which potentially subject the Company to a concentration of credit risk, consist primarily of cash and cash equivalents, short-term investments and trade accounts receivable.

The Company invests or maintains available cash with various banks, principally in the United States, Mexico, Europe and Peru, or in commercial papers of highly-rated companies. As part of its cash management process, the Company regularly monitors the relative credit standing of these institutions.  At December 31, 2014, SCC had invested its cash and cash equivalents and short-term investments as follows:

			% of total		% in one institution
Country	$ in million		cash (1)		of country		of total cash
United States	$	210.8	30.0	%	47.1	%	14.1	%
Switzerland	389.6		55.5	%	100.0	%	55.5	%
Peru	83.9		11.9	%	79.7	%	9.5	%
Mexico	18.3		2.6	%	62.4	%	1.6	%
Total cash and short-term investment	$	702.6	100.0	%

(1)97.2% of the Company’s cash is in U.S. dollars.

During the normal course of business, the Company provides credit to its customers. Although the receivables resulting from these transactions are not collateralized, the Company has not experienced significant problems with the collection of receivables.

The Company is exposed to credit loss in cases where the financial institutions with which it has entered into derivative transactions (commodity, foreign exchange and currency/interest rate swaps) are unable to pay when they owe funds as a result of protection agreements with them. To minimize the risk of such losses, the Company only uses highly-rated financial institutions that meet certain requirements. The Company also periodically reviews the creditworthiness of these institutions to ensure that they are maintaining their ratings. The Company does not anticipate that any of the financial institutions will default on their obligations.

The Company’s largest customers as percentage of accounts receivable and total sales were as follows:

	2014		2013		2012
Accounts receivable trade as of December 31,
Five largest customers	31.2	%	37.1	%	40.0	%
Largest customer	8.0	%	12.2	%	10.4	%
Total sales in year
Five largest customers	34.3	%	28.7	%	28.8	%
Largest customer	8.2	%	8.4	%	7.4	%

NOTE 17-RELATED PARTY TRANSACTIONS:

The Company has entered into certain transactions in the ordinary course of business with parties that are controlling shareholders or their affiliates. These transactions include the lease of office space, air transportation, construction services and products and services related to mining and refining. The Company lends and borrows funds among affiliates for acquisitions and other corporate purposes. These financial transactions bear interest and are subject to review and approval by senior management, as are all related party transactions. It is the Company’s policy that the Audit Committee of the Board of Directors shall review all related party transactions. The Company is prohibited from entering or continuing a material related party transaction that has not been reviewed and approved or ratified by the Audit Committee.

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

131

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

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

In 2005, the Company organized MGE, as a subsidiary of Minera Mexico, for the construction of two power plants to supply power to the Company’s Mexican operations. In May 2010, the Company’s Mexican operations granted a $350 million line of credit to MGE for the construction of the power plants. That line of credit was due on December 31, 2012 and carried an interest rate of 4.4%. In the first quarter of 2012, Controladora de Infraestructura Energetica Mexico, S. A. de C. V., an indirect subsidiary of Grupo Mexico, acquired 99.999% of MGE through a capital subscription of 1,928.6 million Mexican pesos (approximately $150 million), reducing Minera Mexico’s participation to less than 0.001%. As consequence, of this change in control, MGE became an indirect subsidiary of Grupo Mexico. Additionally, at the same time, MGE paid $150 million to the Company’s Mexican operations partially reducing the total debt. At December 31, 2012, the outstanding balance of $184.0 million was restructured as subordinated debt of MGE with an interest rate of 5.75%. MGE will repay its debt to the Company using a percentage of its profits until such time as the debt is satisfied. At December 31, 2014 the remaining balance of the debt was $161.2 million and was recorded as non-current related party receivable on the consolidated balance sheet. Related to this loan, the Company recorded interest income of $9.4 million and $9.9 million in 2014 and 2013, respectively.

In 2012, the Company signed a power purchase agreement with MGE, whereby MGE will supply some of the Company’s Mexican operations with power through 2032. MGE completed construction of its first power plant in June 2013 and the second plant, in the second quarter of 2014. MGE already has the authorization for interconnection with the Mexican electrical system to start operations at the second plant. MGE began supplying power to the Company in December 2013. It is expected that MGE will supply portion of its power output to third-party energy users. See also Note 13 — “Commitments and Contingencies — Other commitments.”

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

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

Total purchased	$	16.4	$	7.9	$	6.7

The Company purchased industrial materials from Higher Technology S.A.C. and paid fees for maintenance services provided by Servicios y Fabricaciones Mecanicas S.A.C. Mr. Carlos Gonzalez, the son of SCC’s Chief Executive Officer, has a proprietary interest in these companies.

The Company purchased industrial material from Sempertrans and its affiliates, which employ Mr. Alejandro Gonzalez as a sales representative. Also, the Company purchased industrial material from Pigoba, S.A. de C.V., a company in which Mr. Alejandro Gonzalez has a proprietary interest. Mr. Alejandro Gonzalez is the son of SCC’s Chief Executive Officer.

The Company purchased industrial material and services from Breaker, S.A. de C.V., a company in which Mr. Jorge Gonzalez, son-in-law of SCC’s Chief Executive Officer, has a proprietary interest, and from Breaker Peru S.A.C., a company in which Mr. Jorge Gonzalez, son-in-law and Mr. Carlos Gonzalez, son of SCC’s Chief Executive Officer have a proprietary interest.

Equity Investment in Affiliate: The Company has a 44.2% participation in Compania Minera Coimolache S.A. (“Coimolache”), which it accounts for on the equity method. Coimolache owns Tantahuatay, a gold mine located in the northern part of Peru. To support the cost of the development of Tantahuatay, the Company loaned $56.6 million to Coimolache. The repayment of this loan was completed in August 2014.

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

NOTE 18-SEGMENT AND RELATED INFORMATION:

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

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

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 information 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.

133

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

The Peruvian operations include two 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 two 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 two copper mines whose mineral output is processed in the same smelter and refinery without distinguishing between the products of the two 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 a separate operating segment from the Mexican open-pit operations due to the very distinct regulatory and political environments in which they operate. The Company’s Senior Management Officers 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 continually deal with a political climate that has a very distinct vision of the mining industry as compared to 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 regards to open-pit operations in the two countries.

The IMMSA segment includes five mines whose minerals are processed in the same refinery. This segment also includes an underground coal mine. 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 very similar regulatory environment of the Mexican open-pit mines, the nature of the products and processes of two Mexican operations vary distinctly. These differences cause the Company’s Senior Management Officers to take a very different approach when analyzing results and making decisions regarding the two Mexican operations.

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

LONG-TERM SALES CONTRACTS:

The following are the significant outstanding long-term contracts:

Under the terms of a sales contract with Mitsui & Co. Ltd. (“Mitsui”), the Company was required to supply Mitsui with 48,000 tons of copper cathodes annually through 2013 to the Asian Market. Premium levels were agreed upon annually based on world market terms. 90,000 tons related to a prior contract (period 1994-2000) will be supplied as follows: 48,000 tons in 2014 and 42,000 tons in 2015.

In 2013, a new long term copper sales agreement was signed with Mitsui for five years, with shipments beginning in 2015. Mitsui and the Company will negotiate market terms and conditions for annual contracts no later than November 30 of the year prior to shipment. The contract considers the following annual volumes of copper cathodes; 6,000 tons for 2015 and 48,000 tons for each of the years from 2016 through 2019. The contract volume would increase by 24,000 tons the year after Tia Maria reaches full production capacity. Failure to reach an agreement on market terms would cancel the annual contract but not the long-term agreement. Under the terms of the agreement all shipments would be to Asia and there are no exclusivity rights for Mitsui or commissions included. This contract may be renewed for additional five year periods, upon the agreement of both parties.

Under the terms of a sales contract with Molibdenos y Metales, S.A., SPCC Peru Branch is required to supply 30,800 tons of molybdenum concentrates from 2014 through 2016. This contract may be extended for one more calendar year during each October to maintain a three year period unless either party decides to terminate the agreement. The sale price of the molybdenum concentrates is based on the monthly average of the high and low Metals Week Dealer Oxide quotation. The roasting charge deduction is agreed based on international market terms.

Under the terms of a sales contract with Molymex, S.A. de C.V., Minera Mexico is required to supply at least the 85% of its molybdenum concentrates production from 2012 through 2015. The sale price of the molybdenum concentrate is based on the monthly average of the high and low Metals Week Dealer Oxide quotation. The roasting charge deduction is negotiated based on international market terms.

ITEM 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNT ON ACCOUNTING AND FINANCIAL DISCLOSURE

None

ITEM 9A. CONTROLS AND PROCEDURES

As of December 31, 2014, the Company conducted an evaluation under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness and the design and operation of the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e).  Based on that evaluation, the Company’s management, including the Chief Executive Officer and the Chief Financial Officer has concluded that the Company’s disclosure controls and procedures were not effective as of December 31, 2014, because of the material weakness in our internal control over financial reporting that is described in “Management’s Report on Internal Control over Financial Reporting.”

However, giving full consideration to the material weakness described below, the Company’s management has concluded that the consolidated financial statements included in this annual report present fairly, in all material respects, the Company’s financial position, results of operations and cash flows for the periods disclosed in conformity with accounting principles generally accepted in the United States of America.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There was no change in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) that occurred during the year ended December 31, 2014 that has materially affected, or is reasonably likely to materially affect, the Company’s internal controls over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the Company.

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

Under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, the Company conducted an evaluation of the effectiveness of its internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organization of the Treadway Commission. Based on the evaluation made under this framework, management concluded that as of December 31, 2014 such internal control over financial reporting was not effective because of the material weakness described below.  In addition, Galaz, Yamazaki, Ruiz Urquiza, S.C. Member of Deloitte Touche Tohmatsu Limited, an independent registered public accounting firm, has issued an adverse report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2014.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement in our annual or interim financial statements will not be prevented or detected on a timely basis. A material weakness exists in the design and operating effectiveness of information technology controls. More specifically, the Company did not establish an effective design of processes and procedures to restrict access to its business planning system (“ERP”) in existence during 2014, known as Ellipse, at its Mexican operations.  As such, the Company failed to ensure that access to key financial systems was limited to appropriate users in order to maintain segregation of duties.  Accordingly, information generated from those systems may have been impacted.  During 2014, the Company spent a significant amount of time preparing for the implementation of certain changes, including a centralized shared-service center to process accounts payable and receivable, as well as a change from its old ERP system to its current business planning system, SAP at its Mexican operations. The Company performed tests over its financial information; based on those tests, management did not detect any unauthorized entries, despite the potential access to those applications.

REMEDIATION PLAN FOR MATERIAL WEAKNESS IN INTERNAL CONTROL OVER FINANCIAL REPORTING

In response to the material weakness described above, the Company has developed a remediation plan, with oversight from the Audit Committee of the Board of Directors. SAP was implemented at the Company’s Mexican operations beginning February 5, 2015. As part of the remediation plan, the Company will implement the security tools that SAP provides and which will allow the Company to assure that access control authorizations are functioning, and that transactions and data entered into the financial and related systems are properly authorized, based on the Company’s organizational structure, positions and assigned responsibilities. The Company believes that this will provide management with assurance that such access is properly restricted to the appropriate personnel for an effective functional segregation.

The Company will implement this remediation plan during 2015.  The Company has put in place processes and procedures, with strict management supervision and monitoring by the Audit Committee of the Board of Directors, to ensure that the remediation plan is in place in 2015. The implementation of the new ERP, SAP, at the Company’s worldwide operations will improve the processes that make up the Company’s internal control over financial reporting and will, as part of its process, require testing for effectiveness. Management believes that these efforts will effectively remediate the material weakness in its internal control over financial reporting that is described above in “Management’s Report on Internal Control over Financial Reporting.” As the Company continues to evaluate and work to improve its internal control over financial reporting, management may take additional measures to address the aforementioned weakness in control or may modify the remediation plan described above.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

We have audited Southern Copper Corporation and subsidiaries (the “Company”) internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.  The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Management’s Report on Internal Control over Financial Reporting” appearing in Item 9A.  Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.  Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on that risk, and performing such other procedures as we considered necessary in the circumstances.  We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the Company’s Board of Directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis.  Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment. We have identified a material weakness in the design and operating effectiveness of information technology controls. More specifically, the Company has not established effective design of processes and procedures to restrict access to its business planning system (“ERP”) in existence during 2014, known as Ellipse, at its Mexican operations.  As such, the Company failed to ensure that access to key financial systems was limited to appropriate users in order to maintain appropriate segregation of duties. Accordingly, information generated from those systems may have been impacted.  This  material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements and financial statement schedules as of and for the year ended December 31, 2014, of the Company and this report does not affect our report on such financial statements and financial statement schedules.

In our opinion, because of the effect of the material weakness identified above on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We do not express an opinion or any other form of assurance on managements statements regarding remediation contained in the section “Remediation Plan for Material Weakness in Internal Control Over Financial Reporting” of “Management’s Report on Internal Control over Financial Reporting” appearing in Item 9A.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedules as of and for the year ended December 31, 2014 of the Company and our report dated February 27, 2015 expressed an unqualified opinion on those financial statements and financial statement schedules.
