The following discussion provides information that management believes is relevant to an assessment and understanding of the condensed consolidated financial condition and results of operations of Southern Copper Corporation and its subsidiaries (collectively, "SCC", "the Company", "our", and "we"). This item should be read in conjunction with our interim unaudited Condensed Consolidated Financial Statements and the notes thereto included in this quarterly report. Additionally, the following discussion and analysis should be read in conjunction with the Management Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements included in Part II of our annual report on Form 10-K for the year ended December 31, 2019.





EXECUTIVE OVERVIEW



Business: Our business is primarily the production and sale of copper. In the process of producing copper, a number of valuable metallurgical by-products are recovered, which we also produce and sell. Market forces outside of our control largely determine the sale prices for our products. Our management, therefore, focuses on value creation through copper production, cost control, production enhancement and maintaining a prudent capital structure to remain profitable. We endeavor to achieve these goals through capital spending programs, exploration efforts and cost reduction programs. Our aim is to remain profitable during periods of low copper prices and to maximize financial performance in periods of high copper prices.

We are one of the world's largest copper mining companies in terms of production and sales with our principal operations in Peru and Mexico. We also have active ongoing exploration programs in Chile, Argentina and Ecuador. In addition to copper, we produce significant amounts of other metals, either as a by-product of the copper process or in a number of dedicated mining facilities in Mexico.

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

Changes in copper, molybdenum, silver and zinc prices: In the first quarter of

2020, the average LME and COMEX copper prices were $2.56 and $2.57 per pound,

respectively, 9.2% and 8.5% lower than in the same period of 2019, ? respectively. During the first quarter of 2020 per pound LME spot copper prices

ranged from $2.09 to $2.86. Average molybdenum prices in the first quarter of

2020 decreased 18.3% and zinc prices decreased by 21.1%, when compared to the

average prices in the first quarter of 2019. Average silver prices increased

8.7% in the first quarter of 2020 when compared to the same period of 2019.

Sales structure: In the first quarter of 2020, approximately 79% of our revenue ? came from the sale of copper, 7% from molybdenum, 5% from silver, 4% from zinc

and 5% from various other products, including gold, sulfuric acid and other


  materials.



Copper: During the first quarter of 2020 the LME copper price decreased, from

an average of $2.82 per pound in the first quarter of 2019 to $2.56 (-9.2%).

Currently we are seeing prices in the range of $2.20 to $2.30 per pound as a ? reflection of the impact of the COVID-19 crisis on the demand and on copper

supply. The world is currently experiencing the public health, financial and

economic impacts of the COVID-19 pandemic. Since it is affecting both, supply

and demand, at this point it is difficult to assess the full effect of this

crisis on the copper market balance and on copper prices.

On a normal year, we expect to have a seasonal copper inventories increase in the first quarter of the year due to the New Year festivities of China and the winter impact on demand. This year we had the COVID-19 outbreak as an additional factor affecting copper demand and supply, and copper prices. At the end of 2019, copper demand for refined copper was estimated at 23.6 million tons and global inventories were 599,000 tons. By the end of February 2020, they add up to 917,000 tons, or 318,000 tons higher than the inventories at the end of 2019. On Friday, April 24, global inventories were estimated at 925,000 tons, this is 326,000 tons over the closing of 2019 and a relatively stable mark since they increased at the end of February. We believe this reflects the mentioned seasonal effect as well as an additional market surplus created by the COVID-19 pandemic.

In a normal year, we expect the additional inventories to be partially absorbed through the rest of the year. For 2020, it is difficult to estimate when this may happen since we are seeing a much weaker demand than last year.

Molybdenum: Represented 7.3% of our sales in the first quarter of 2020. ? Molybdenum prices averaged $9.56 per pound in the first quarter of 2020,

compared to $11.70 in the same period of 2019, a 18.3% decrease.

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

Zinc: Represented 3.8% of our sales in the first quarter of 2020. Zinc has very ? good long term fundamentals due to its significant industrial consumption and


  the expected production.



Silver: Represented 5.1% of our sales in the first quarter of 2020 and it is ? currently our second by-product. We believe that silver prices will have

support due to its industrial uses as well as its linkage to gold as a value

shelter in times of economic uncertainty.

?Cost: Our operating costs and expenses for the first quarter of 2020 and 2019 were as follows:



                                                                            Variance
                                                2020         2019        Value       %

Operating costs and expenses (in millions) $ 1,186.4 $ 1,059.7 $ 126.7 12.0 %

The increase was mainly due to higher cost of sales at all our operating segments; as well as higher depreciation, amortization and depletion at our Peruvian and Mexican open pit segments.

Capital Investments: In the first quarter of 2020 we spent $101.0 million on ? capital investments, 41.7% lower than in the same period of 2019, and

represented 46.7% of net income.

COVID-19: In March 2020, the WHO classified the COVID-19 outbreak as a pandemic

based on the rapid increase in global exposure. The full impact of the COVID-19

outbreak will continue and its magnitude on the Company's financial condition,

liquidity and future results of operations is uncertain. Senior Management is

actively monitoring the global situation on the Company´s financial condition, ? liquidity, operations, suppliers, industry and workforce and focusing

principally on the health, safety and well-being of our employees, their

families and the communities where we have operations. As of March 31, 2020,

there have not been major delays in the supply of material and services

critical for the operations, and sales. Additionally, shipments of products and

collections have had no known major delays.

As of March 31, 2020, despite the drop in copper price which decreased to an average of $2.56 per pound (LME) in the first quarter 2020 compared with $2.67 in the fourth quarter 2019 and $2.82 in the first quarter of 2019, the Company maintains a solid financial position and performance as shown in the table below:

Governmental authorities have declared that essential economic activities must continue during the COVID-19 health emergency. These activities include industrial mining and/or any other activity necessary to secure the production and distribution of essential services such as electricity, medical and hospital infrastructure and manufacture of health related supplies and technological equipment, which necessarily implies critical components and goods only produced by industrial mining, which are essential in the global supply chains to manufacture products and services to fight the pandemic, such as steel, copper, gold, coal, silver, zinc and cement, among many others.

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

At the present time, our operations are in compliance with all sanitary and government regulations and maintaining proper environmental safeguards. It should be noted that to date, there have been no known cases of COVID-19 contagion among our employees in our mining facilities in Mexico and Peru. Our COVID-19 emergency protocol has reinforced preventive measures such as disinfecting, clinical monitoring before work, cleaning and sanitizing of work areas and respect for social distancing. We have also restricted access to contractors, suppliers and personnel that is not indispensable and enforced multiple actions to limit workforce exposure to COVID-19 such as travel restrictions, prohibiting face-to-face meetings and urging frequent hand washing, as well as adherence to all other health, safety and social distancing measures issued by governmental authorities.

As the spread of COVID-19 continues, reduced demand for products (including disruptions at the facilities of our transportation service providers or supply vendors) could have a material adverse effect on our business, operations and financial performance.

KEY MATTERS:


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

Net sales in the first quarter of 2020 were 1.9% lower than in the same period of 2019 mainly as a result of lower copper (-9.2% LME) and molybdenum (-18.3%) prices. This effect was largely offset by higher sales volumes of copper (+10.6%), molybdenum (+41.9%), silver (+8.2%) and zinc (+7.1%).

Net income in the first quarter of 2020 was 44.7% lower than in the first quarter of 2019. This decrease was mainly due to lower sales and higher operating costs (+12.0%). Costs increased due to higher sales volumes, leachable material and third parties copper purchases. The higher costs were partially offset by lower fuel cost and the effect of exchange rates depreciation on local currencies costs.

Production: The table below highlights our mine production data for the three months ended March 31, 2020 and 2019:

Mined copper production in the first quarter of 2020 increased by 5.9% to 533.5 million pounds compared to 504.0 million pounds in the first quarter of 2019. This increase was principally due to:

Higher production at our Peruvian mines as result of the new Toquepala ? concentrator and higher ore grades and recoveries in the Cuajone mine;

partially offset by

? Lower production at the Buenavista mine due to lower ore grades.

Molybdenum production increased 39.8% in the first quarter of 2020 when compared with the first quarter of 2019 as result of higher production at all our mines, principally at the Toquepala mine (+280.3%) due to the new molybdenum plant that started production in April 2019 and higher production at the Cuajone mine (+42.6%) as result of higher grades.

  Table of Contents

Silver mine production increased by 21.6% in the first quarter of 2020 due to higher production at all our mines, highlighting the IMMSA operations (+35.7%), principally at the San Martin mine.

Mined zinc production increased 3.8% in the first quarter of 2020, compared with the same period of 2019 , due to higher production at the Charcas, Santa Barbara and San Martin mines, partially offset by lower production at the Santa Eulalia mine, which suspended operations due to a flooding.

Operating Cash Costs: An overall benchmark used by us and a common industry metric to measure performance is operating cash costs per pound of copper produced. Operating cash cost is a non-GAAP measure that does not have a standardized meaning and may not be comparable to similarly titled measures provided by other companies. This non-GAAP information should not be considered in isolation or as substitute for measures of performance determined in accordance with GAAP. A reconciliation of our operating cash cost per pound of copper produced to the cost of sales (exclusive of depreciation, amortization and depletion) as presented in the condensed consolidated statement of earnings is presented under the subheading, "Non-GAAP Information Reconciliation" on page 51. We disclose operating cash cost per pound of copper produced, both before and net of by-product revenues.

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

In our calculation of operating cash cost per pound of copper produced, we exclude depreciation, amortization and depletion, which are considered non-cash expenses. Exploration is considered a discretionary expenditure and is also excluded. Workers' participation provisions are determined on the basis of pre-tax earnings and are also excluded. 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 net of by-product revenues as operating cash cost per pound of copper produced, as defined in the previous paragraph, less by-product revenues and net revenue (loss) on sale of metal purchased from third parties.

In our calculation of operating cash cost per pound of copper produced, net of by-product revenues, we credit against our costs the revenues from the sale of all our by-products, including, molybdenum, zinc, silver, gold, etc. and the net revenue (loss) on sale of metals purchased from third parties. We disclose this measure including the by-product revenues in this way because we consider our principal business to be the production and sale of copper. As part of our copper production process, much of our by-products are recovered. These by-products, as well as the processing of copper purchased from third parties, are a supplemental part of our production process and their sales value contribute to 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 before by-product revenues allow us to monitor our cost structure and address with operating management areas of concern. The measure operating cash cost per pound of copper produced net of by-product revenues is a common measure used in the copper industry and is a useful management tool that allows us to track our performance and better allocate our resources. This measure is also used in our investment project evaluation process to determine a project's potential contribution to our operations, its competitiveness and its relative strength in different price scenarios. The expected contribution of by-products is generally a significant factor used by the copper industry in determining whether to move forward with the development of a new mining project. As the price of our by-product commodities can have significant fluctuations from period to period, the value of its contribution to our costs can be volatile.

(2) Net of metallurgical losses.

As set forth on the above table, our per pound cash cost before by-product revenues and net of it, in the first quarter of 2020, were 7.3% and 14.5% lower when compared with the first quarter of 2019, respectively. This decrease was the result of the unit cost effect of 5.5% higher production and higher 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 metal prices. For the remaining nine months of 2020, assuming that expected metal production and sales are achieved, that tax rates are unchanged and giving no effect to potential hedging programs, metal price sensitivity factors would indicate the following change in estimated net income attributable to SCC resulting from metal price changes:






                                            Copper      Molybdenum       Zinc         Silver

Change in net earnings (in millions) $ 137.8 $ 36.6 $ 14.6 $ 10.5

Business Segments: We view our Company as having three reportable segments and manage it on the basis of these segments. These segments are (1) our Peruvian operations, (2) our Mexican open-pit operations and (3) our Mexican underground operations, known as our IMMSA unit. Our Peruvian operations include the Toquepala and Cuajone mine complexes and the smelting and refining plants, industrial railroad and port facilities that service both mines. The Peruvian operations produce copper, with significant by-product production of molybdenum, silver and other material. Our Mexican open-pit operations include La Caridad and Buenavista mine complexes, the smelting and refining plants and support facilities, which service both mines. The Mexican open pit operations produce copper, with significant by-product production of molybdenum, silver and other material. Our IMMSA unit includes five underground mines that produce zinc, lead, copper, silver and gold, 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 14 "Segment and Related Information" of our condensed consolidated financial statements.

Inflation and Exchange Rate Effect of the Peruvian Sol and the Mexican Peso: Our functional currency is the U.S. dollar and our revenues are primarily denominated in U.S. dollars. Significant portions of our operating costs are denominated in Peruvian sol and Mexican pesos. Accordingly, when inflation and currency devaluation/appreciation of the Peruvian currency and Mexican currency occur, our operating results can be affected. In recent years, we do believe



                                       40

such changes have not had a material effect on our results and financial position. Please see Item 3. "Quantitative and Qualitative Disclosures about Market Risk" for more detailed information.

Capital Investment Programs: We made capital investments of $101.0 million in the three months ended March 31, 2020, compared with $173.1 million in the same period of 2019. In general, the capital investments and investment projects described below are intended to increase production, decrease costs or address social and environmental commitments.

Set forth below are descriptions of some of our current expected capital investment programs. We expect to meet the cash requirements for these projects from cash on hand, internally generated funds and from additional external financing, including funding received in September 2019. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy, market conditions or the COVID-19 pandemic.





Projects in Mexico:


Buenavista Zinc - Sonora: This project is located within the Buenavista facility and includes the development of a new concentrator to produce approximately 80,000 tons of zinc and 20,000 tons of copper per year. Currently, we have completed the basic engineering and the detailed engineering is in process. The site preparation has started and the purchase orders for the major equipment have been placed. The project is fully permitted. The project´s budget is $413 million, and we expect to initiate operations in the third quarter of 2022. When completed, this new facility will double the Company's zinc production capacity and will provide 490 direct jobs and 1,470 indirect jobs.

Pilares - Sonora: This project, located six kilometers from La Caridad, will be developed as an open-pit mine operation with an annual production capacity of 35,000 tons of copper in concentrate. The ore will be transported from the pit to the primary crushers of the La Caridad copper concentrator through a new 25-meter wide off-road facility for mining trucks, and will significantly improve the over-all mineral ore grade (combining the 0.78% expected from Pilares with 0.34% from La Caridad). The budget for Pilares is $159 million and we expect it to start production during the first half of 2022. The connection road between Pilares mine and La Caridad mine is now under construction.

El Pilar - Sonora: This is a low capital intensity copper development project strategically located in Sonora, Mexico, approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and probable reserves of 325 million tons of ore with an average copper grade of 0.287%. El Pilar will operate as a conventional open-pit mine and copper cathodes will be produced using the highly cost efficient and environmentally friendly SX-EW technology. We estimate a development investment of approximately $310 million. The construction of the pilot plant is finished and the production tests have begun. We expect this project to start production during 2023.

The San Martin mine recovery program. After eleven years of an illegal stoppage, we resumed control of the San Martin mine in August 2018. The San Martin facilities deteriorated during this period but we undertook a major renovation and restarted operations during the second quarter of 2019. Currently, the mine has 200,000 tons of ore and the concentrator has initiated production. In 2019, we produced 5,837 tons of zinc, 1.2 million ounces of silver and 1,335 tons of copper. The budget of the restoration program is $97.7 million. At March 31, 2020 the program had a total expense of $78.6 million.





Projects in Peru:


Our main capital projects in Peru are the following:

Toquepala Expansion Project - Tacna: This $1,320 million project includes a new state-of-the-art concentrator which increased Toquepala's annual copper production to 258,000 tons in 2019, a 51% production increase, when compared to 2018. Construction of the project was completed and production began in the fourth quarter of 2018. Full production was reached in the second quarter of 2019. We are in the administrative close-out process for this project.

Tailings disposal at Quebrada Honda - Moquegua: This project increases the height of the existing Quebrada Honda dam to impound future tailings from the Toquepala and Cuajone mills and will extend the expected life of this tailings facility

by 25 years. The first stage and construction of the drainage system for the lateral dam is finished. We finished the second stage with the installation of a new cyclone battery station that allows us to place more slurry at the dams. We are evaluating improvements in operational processes of this facility. The project has a total budgeted cost of $116 million and we have invested $105.5 million through March 31, 2020.





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, market conditions or the COVID-19 pandemic.

El Arco - Baja California: This is a world class copper deposit located in the central part of the Baja California peninsula, with ore reserves of over 2.6 billion tons with an ore grade of 0.410% and 0.113 grams of gold per ton. This project includes an open-pit mine combining concentrator and SX-EW operations with an estimated production of 135,000 tons of copper and 64,000 ounces of gold annually. We are currently in the land acquisition process for the project.

Tia Maria - Arequipa: On July 8, 2019, we received the construction permit for this 120,000 ton annual SX-EW copper greenfield project with a total capital budget of $1,400 million. This permit was obtained after completing an exhaustive review process, complying with all established regulatory requirements and addressing all observations raised.

The challenges to the construction permit were overcome when on October 30, 2019, the Mining Council of the Peruvian Ministry of Energy and Mines ratified the construction permit for the Tia Maria project.

We guarantee to the population of Islay that the Tia Maria project will not adversely affect other local economic activities because we will use desalinated seawater for our operations and, for the transport of our supplies and copper production, we will build an 32 kilometer industrial railway and an access road at a safe distance from the Tambo Valley.

Our social programs in education, healthcare and productive development will continue to improve the quality of life, and the agricultural and livestock activities in the Tambo Valley, as well as fishing and tourism in Islay. During the construction and operation phase, hiring local labor will be a priority. For this purpose, we have successfully launched in June 2019 the free technical training program "Forging the Future", which will benefit 700 persons in this province in 2019-20. After training, the participants will be eligible to apply for one of the estimated 9,000 jobs (3,600 direct and 5,400 indirect) required during the Tia Maria construction phase. We strongly believe that the initiation of construction activities for Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region.

When in operation, we expect Tia Maria will generate a significant contribution through mining royalties and taxes from day-one and will directly employ 600 workers and indirectly provide jobs for another 4,200 workers.

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

Los Chancas - Apurimac: This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit. Current estimates indicate the presence of 545 million tons of mineralized material with a copper content of 0.59%, molybdenum content of 0.04% and 0.039 grams of gold per ton, as well as 181 million tons of mineralized leachable material with a total copper content of 0.357%. Los Chancas project envisions an open-pit mine with a combined operation of concentrator and SX-EW processes to annually produce 130,000 tons of copper and 7,500 tons of molybdenum. The estimated capital investment is $2,800 million and is expected to be in operation in 2026. In 2019, we continued with the development of social and environmental improvements for the local communities. For 2020, we plan to continue with these activities and to conclude the environmental impact assessment of the project.

Michiquillay Project - Cajamarca: On June 12, 2018, Southern Copper signed a contract and made an initial payment of $12.5 million for the acquisition of the Michiquillay project in Cajamarca, Peru. The Company has created a multidisciplinary management team to plan the development of this project. As part of this plan, the Company has established contact with the local and regional authorities and communities in order to promote programs for the sustainable development of the area. In 2019, we developed social and environmental programs for the local communities and began a semi-detailed environmental impact assessment. This will allow us to begin a 40,000 meter diamond drilling program in 2021, to verify and update the estimated mineralized materials of the project.

Michiquillay is a world class mining project with estimated mineralized material of 1,150 million tons with an estimated copper grade of 0.63%. When developed, we expect Michiquillay to produce 225,000 tons of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years, at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2026, with Michiquillay becoming one of Peru´s largest copper mines. The project will create significant business opportunities in the Cajamarca region, generate new jobs for the local communities and contribute with taxes and royalties to the national, regional and local governments.

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





ACCOUNTING ESTIMATES



Our discussion and analysis of financial condition and results of operations, as well as quantitative and qualitative disclosures about market risks, are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. Preparation of these consolidated financial statements requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We make our best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: ore reserves, revenue recognition, ore stockpiles on leach pads and related amortization, estimated impairment of assets, asset retirement obligations, determination of discount rates related to the financial lease liabilities, classification of operating leases versus financial leases, valuation allowances for deferred tax assets, unrecognized tax benefits and fair value of financial instruments. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Long-term inventory-Ore stockpiles on leach pads:

On January 1, 2020 the Company aligned its capitalization method for its Peruvian and Mexican operations to capitalize based on the allocation of copper content recoverable between ore and leach material. In addition, the inventory consumption is now valued at the average unit cost, instead of the declining percentages of recovery method used previously. As a result of these changes, the value of capitalized material decreased by $48.8 million and the consumption increased by $10.3 million.
