EXECUTIVE SUMMARY





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



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



EXECUTIVE OVERVIEW



Business: Our business is primarily the production and sale of copper. In the
process of producing copper, a number of valuable metallurgical by-products are
recovered, which we also produce and sell. Market forces outside of our control
largely determine the sale prices for our products. Our management, therefore,
focuses on value creation through copper production, cost control, production
enhancement and maintaining a prudent capital structure to remain profitable. We
endeavor to achieve these goals through capital spending programs, exploration
efforts and cost reduction programs. Our aim is to remain profitable during
periods of low copper prices and to maximize financial performance in periods of
high copper prices. We are one of the world's largest copper mining companies in
terms of production and sales and our principal operations are in Peru and
Mexico. We also have an active ongoing exploration program in Chile, Argentina
and Ecuador.


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






Copper contained in ore reserves    Thousand tons
Mexican open­pit                           30,346
Peruvian operations                        22,439
IMMSA                                         256
Development projects                       14,647
Total                                      67,688



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

Sales structure: In the last three years, approximately 81.0% of our revenues ? came from the sale of copper, 7.0% from molybdenum, 4.0% from zinc, 5.0% from

silver and 3.0% from various other products, including gold, sulfuric acid and


  other materials.



Copper: In the last quarter of 2020, the LME copper price increased, from an

average of $2.67 per pound in the fourth quarter of 2019 to $3.25 (+21.7%). ? Currently, we are seeing prices over $3.60 per pound, which bodes a positive


  outlook for the 2021 copper market. We believe the following factors are
  influencing the market:



A worldwide recovery in copper demand for industrial uses, driven mainly by a

? sustained recovery in economic activity in China and other Asian economies and

in the European auto industry.

Regarding China, it should also be noted that copper scrap imports have

? decreased by 48% in the last 10 months of 2020, which led to a subsequent

increase in Chinese consumption of refined copper.

? The combined inventories of the LME, Comex, Shanghai and Bonded warehouses


   closed 2020 at their lowest levels since December 2014.



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

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


  decrease.



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

Zinc: Although average zinc prices decreased in 2020 compared with 2019 ? (-11.0%), we believe zinc has very good long-term fundamentals due to its

significant industrial consumption and expected production. Zinc represented


  3.1% of our sales in 2020.



Silver: We believe that silver prices will have support due to its industrial ? uses as well as being perceived as a value shelter in times of economic

uncertainty. Silver represented 5.6% of our sales in 2020.

Production: In 2021 and 2022, we expect to produce 943,000 tons of copper given ? that production during these periods will be affected by a temporary reduction


  in ore grade and recovery at our Peruvian operations.



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





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

2020
production levels.


Capital investments: Capital investments were $592.2 million for 2020. This is

16.3% lower than in 2019, and represented 37.7% of net income. Our growth ? program to develop the full production potential of our Company is underway. We


  are currently developing a new organic growth plan to increase our copper
  volume production to 1.9 million tons by 2028 with the development of new
  projects.



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





COVID-19



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



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

The Company maintains a solid financial position and performance level. We
believe this has allowed and will continue to allow us to deal with the effects
of the pandemic in a way that prevents adverse material effects on our
operations and financial results. The table below compares some of our financial
information as of and for the years ended December 31, 2020 and 2019:

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



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



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

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.

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



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



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

2020 compared to 2019:


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

? Higher production at the Cuajone mine (+7.8%), which was driven by an increase

in ore grades and recoveries.

? Higher production at the La Caridad mine (+1.8%).

? Higher production at the IMMSA operations (+24.6%), which was attributable to


  an increase in ore grades.




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



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



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



2019 compared to 2018:


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

Higher production at the Toquepala mine (+51.5%), as a result of additional ? copper production of 93,108 tons from the successful ramping up of the new

concentrator.

? Higher production at the Buenavista mine (+5.8%) due to operating improvements

at our new Buenavista plants, the SX/EW (+12.2%) and concentrator (+4.0%).




                                       73

  Table of Contents

? Higher production at the IMMSA operations (+32.9%), as result of the

restoration of the San Martin mine operations.






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



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



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


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



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



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



We define operating cash cost per pound of copper produced net of by-product
revenues as operating cash cost per pound of copper produced, as defined in the
previous paragraph, less by-product revenues and net revenue (loss) on sale of
metal purchased from third parties.



In our calculation of operating cash cost per pound of copper produced, net of
by-product revenues, we credit against our costs the revenues from the sale of
all our by-products, including, molybdenum, zinc, silver, gold, etc. and the net
revenue (loss) on sale of metals purchased from third parties. We disclose this
measure including the by-product revenues in this way because we consider our
principal business to be the production and sale of copper. As part of our
copper production process, much of our by-products are recovered. These
by-products, as well as the processing of copper purchased from third parties,
are a supplemental part of our production process and their sales value
contribute to covering part of our incurred fixed costs. We believe that our
Company is viewed by the investment community as a copper company, and is
valued, in large part, by the investment community's view of the copper market
and our ability to produce copper at a reasonable cost.



We believe that both of these measures are useful tools for our management and
our stakeholders. Our cash costs before by-product revenues allow us to monitor
our cost structure and address areas of concern within operating management. The
measure operating cash cost per pound of copper produced net of by-product
revenues is a common measure used in

                                       74

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

2020 compared to 2019:



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



2019 compared to 2018:



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



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

and
silver.



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

Business Segments: We view our Company as having three reportable segments and
manage it on the basis of these segments. These segments are (1) our Peruvian
operations, (2) our Mexican open-pit operations and (3) our Mexican underground
operations, known as our IMMSA unit. Our Peruvian operations include the
Toquepala and Cuajone mine complexes and the smelting and refining plants,
industrial railroad and port facilities that service both mines. Our Mexican
open-pit operations include La Caridad and Buenavista mine complexes, the
smelting and refining plants and support facilities, which service both mines.
Our IMMSA unit includes five underground mines and several industrial processing
facilities.



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



Inflation and Exchange Rate Effect of the Peruvian sol and the Mexican peso: Our
functional currency is the U.S. dollar and our revenues are primarily
denominated in U.S. dollars. Significant portions of our operating costs are
denominated in Peruvian sol and Mexican pesos. Accordingly, when inflation and
currency devaluation/appreciation of the Peruvian and Mexican currency occur,
our operating results can be affected. In recent years, we believe these changes
have had no material effect on our results and financial position. Please see
Item 7A "Quantitative and Qualitative Disclosures about Market Risk" for more
detailed information.


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

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



Projects in Mexico:



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



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

0.78%

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



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



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



Projects in Peru:



Quebrada Honda dam expansion - Tacna: This project aims to enlarge the main and
lateral dams in Quebrada Honda and includes the relocation of some facilities
due to dam growth and implementation of other facilities for water recovery,
among other factors. As of December 31, 2020, the engineering study is complete
and we have initiated the procurement process for the necessary materials and
equipment. This project has a total budget of $140.0 million, of which we have
invested $32 million as of December 31, 2020. Progress on the Project is 41%
according to the plan.



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



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



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

via
royalties and taxes.



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



Potential projects:


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



                                       78

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

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



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



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



Michiquillay is a world class mining project with estimated mineralized material
of 1,150 million tons with an estimated copper grade of 0.63%. When developed,
we expect Michiquillay to produce 225,000 tons of copper per year (along with
by-products of molybdenum, gold and silver) for an initial mine life of more
than 25 years and at a competitive cash-cost. We estimate an investment of
approximately $2.5 billion will be required and expect production start-up by
2028. We believe that Michiquillay will become one of Peru´s largest copper
mines. The project will create significant business opportunities in the
Cajamarca region, generate new jobs for the local communities and contribute
with taxes and royalties to the local, regional and national governments.



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

is
accurate.


CRITICAL ACCOUNTING POLICIES AND ESTIMATES

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





Our discussion and analysis of financial condition and results of operations, as
well as quantitative and qualitative disclosures about market risks, are based
upon our consolidated financial statements, which have been prepared in
accordance with U.S. GAAP. Preparation of these consolidated financial
statements requires our management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosures of contingent
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. We make our best
estimate of the ultimate outcome for these items based on historical trends and
other information available when the financial statements are prepared. Changes
in estimates are recognized in accordance with the accounting rules for the
estimate, which is typically in the period when new information becomes
available to

                                       79

  Table of Contents

management. Areas where the nature of the estimate makes it reasonably possible
that actual results could materially differ from amounts estimated include: ore
reserves, revenue recognition, ore stockpiles on leach pads and related
amortization, estimated impairment of assets, asset retirement obligations,
determination of discount rates related to the operating lease liabilities,
valuation allowances for deferred tax assets and unrecognized tax benefits. We
base our estimates on historical experience and on various other assumptions
that we believe to be reasonable under the circumstances. Actual results may
differ from these estimates under different assumptions or conditions.



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



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


                                                              Average
                            2020      2019       2018        2020 - 2018
Copper ($per pound)        $ 2.80    $  2.72    $  2.93    $        2.82
Molybdenum ($per pound)    $ 8.69    $ 11.35    $ 11.94    $       10.66




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



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



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



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



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

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



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





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



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

that
the change is enacted.



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



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



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

                                       81

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


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



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



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

of
lease payments.

NET SALES



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



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

Total income tax provision        $ 1,174.4    $ 945.3    $ 1,053.5
The increase in the 2020 effective income tax rate from the prior year was
primarily attributable to a movement in exchange gains and losses from the
devaluation of the Mexican peso and the Peruvian sol against the U.S. dollar; an
increase in the Peruvian special mining tax; and an increase in the Mexican and
Peruvian royalty. In 2018 the Company, pursuant to SAB 118, completed its
analysis of the effects of the 2017 U.S. tax reform and recorded a non-cash tax
provision of $30.9 million in addition to the non-cash amount of $785.9 recorded
in 2017. After applying the conditions of US tax reform in 2017, the
aforementioned led to a total non-cash tax provision for 2017 and 2018 to $816.8
million.


Equity earnings of affiliate

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

Net Income attributable to the non-controlling interest





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



Income attributable to SCC



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



SEGMENT RESULTS ANALYSIS

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



? $(236.0) million increase in trade accounts receivable, which was mainly driven

by a significant increase in copper prices during the last quarter of 2020.

$223.6 million of net decrease in inventory, which included a $165.2 million ? decrease in the leaching inventory mainly at our Peruvian operations, and a

$36.4 million decrease in the finished goods inventory, principally at our

Mexican operations.

$313.8 million increase in accounts payable and accrued liabilities, which ? primarily reflected growth in income taxes and workers' participation accruals

at our Peruvian and Mexican operations.

$182.3 million decrease in other operating assets and liabilities, which mainly ? included a decrease in prepaid taxes and a drop in receivables to related


  parties.



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

$(184.9) million decrease in accounts payable and accrued liabilities, which ? included principally income taxes and workers' participation payments as a

result of higher earnings at our Mexican and Peruvian operations in 2018.

? $(10.5) million increase in trade accounts receivable mainly because of higher


  sales volumes at our Peruvian operations.

Other Liquidity Considerations


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



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



Share repurchase program: In 2008, our Board of Directors ("BOD") authorized a
$500 million share repurchase program that has since been increased by the BOD
and is currently authorized to $3 billion. Since the inception of the program
through December 31, 2020, we have purchased 119.5 million shares of our common
stock at a cost of $2.9 billion. These shares are available for general
corporate purposes. We may purchase additional shares of our common stock from
time to time based on market conditions and other factors. This repurchase
program has no expiration date and may be modified or discontinued at any time.
For further details please see Item 5 "Market for Registrant's Common Equity,
Related Stockholder Matters and Issuer Purchases of Equity Securities-SCC common
stock repurchase plan."


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





FINANCING



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



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



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



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





Capital Investment Program


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

The above table does not include any scheduled payments related to U.S.

uncertain tax position liabilities because there is often a high degree of

uncertainty regarding the timing of future cash outflows. As of December 31, (a) 2020, the tax liability recognized by the Company is $66.1 million and is

netted against the deferred tax asset in the consolidated Balance Sheet.


    Please refer to Note 7 "Income Taxes" of the consolidated financial
    statements.



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

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


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



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



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



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



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

Kallpa,

                                       94

  Table of Contents

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



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



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



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





CYBERSECURITY



Our operations depend upon information technology systems that may be subject to
disruption, damage or failure from different sources, including, without
limitation, installation of malicious software, computer viruses, security
breaches, cyber-attacks and defects in design. In recent years, cybersecurity
incidents have increased in frequency and include, but are not limited to,
malicious software, attempts to gain unauthorized access to data and other
electronic security breaches that could lead to disruptions in systems,
unauthorized release of confidential or otherwise protected information and the
corruption of data. We have implemented appropriate preventative measures to
mitigate potential risks by implementing an information security management
system, which ensures implementing controls that are frequently reviewed and
tested, including a risk matrix that considers the possible threats through an
impact and probability analysis, actions to avoid or mitigate them and the
corresponding testing plan. In 2020, we did not have any material cybersecurity
breaches in our systems.



CLIMATE CHANGE



Peruvian operations: On April 17, 2018, the Peruvian government enacted Law N.
30754, establishing a Climate Change Framework. Through this law, promoting
public and private investments in climate change management is declared to be of
national interest. The law proposes to create an institutional framework to
address climate change in Peru, outlining new measures, particularly with
respect to climate change mitigation. It includes, for example, provisions
regarding: increasing carbon capture and use of carbon sinks; afforestation and
reforestation practices; land use changes; and sustainable systems of
transportation, solid waste management, and energy systems. This is the first
climate change framework law in Latin America to incorporate obligations from
the Paris Agreement. Regulations to this law were enacted by Supreme Decree
013-2019, which was published on December 31, 2019 and are applicable to all
Peruvian institutions and agencies. It is expected that further Peruvian
regulations will be applicable to non-governmental entities. The Company
anticipates initiating a multi-year process to adopt applicable reporting
recommendations of the Task-Force on Climate Related Financial Disclosures
(TCFD) once new Peruvian climate change regulations applicable to
non-governmental entities are implemented. The Company is committed to the
environment and to managing climate-related impacts. The Company's focus is to
seek continuous improvement in the responsible use of natural resources while
complying with strict applicable legal standards for prevention, mitigation,
control and remediation of environmental impacts. Implementing continuous
improvement in the Company's processes improves efficiency in the use and
consumption of energy, water, and other natural resources.



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

                                       95

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