TRAIN IN SCC PORT, ILO, MOQUEGUA, PERU

Letter to ShareholdersAnnual Report 2023 
 
Despite challenges, we achieved good results in 2023.

Copper production in 2023 increased 1.8% YoY to 911,014 tons. 

The year-end result was driven primarily by an uptick in production 

at  our  Peruvian  operations  (+9.5%)  and  was  partially  offset  by  a 

2.9%  reduction  in  production  at  our  Mexican  operations,  which 

reflected a drop in ore grades, mineral processing, and recovery.

In the second half of 2023, our Buenavista operation was impacted 

by  a  reduction  in  freshwater  levels  given  that  we  still  lack  the 

permits we expect to receive to build a pipeline (approximately 20 

km) to transport water from the wells to the operations and nearby 

townsites.

Molybdenum production was 26,836 tons in 2023, which topped 

5

the figure reported in 2022 by 2.3%. This increase was driven by 

higher  production  at  all  our  mines,  except  for  Toquepala  mine, 

where  grades  and  recoveries  dropped.  Mined  zinc  production 

rose 9.2% YoY due to higher production at the Charcas and Santa 

Barbara mines.

In 2023, copper 
production reached  
911,014 tons and net 
income was $2,425.2 
million.

Net sales in 2023 were $9,895.8 million, this is $152 million or 1.5% lower than net 

sales in 2022. This result was driven by higher sales volumes of copper (+2.2%) and 

molybdenum  (+2.3%)  and  better  prices  molybdenum  (+27.5%)  and  silver  (+7.6%). 

This situation was partially offset by a decrease in the price of copper (LME -3.8%) and 

zinc (-24.1%) and by a reduction in the sales volume of silver (-4.3%) and zinc (-1.4%).

Net income was $2,425.2 million, 8.1% lower than in 2022. The net income margin in 

2023 was 24.5%, versus 26.3% in 2022. The operating cash cost per pound of copper, 

including by-product revenue credits, was $1.03 in 2023. This 25-cent increase in the 

cash cost (+32.6%), compared to the $0.78 reported in 2022, was mainly attributable 

to 17-cent per pound increase in the production cost and an 8-cent reduction in by-

product revenue credits. However, we believe Southern Copper has the lowest cash 

cost of any copper producer.

Major  improvements  in  water  recovery.  Over  the  last  four  years,  we  have  reduced 

water  use  at  our  operations.  In  2023,  we  used  0.53m3  of  water  per  milled  ton  of 

mineral  versus  0.64  m3  in  2020,  which  translated  into  a  17%  uptick  in  efficiency. 

6

Improvement has been driven mainly by the Company’s initiatives to recover water 

from our Quebrada Honda tailings dam in Peru and by an uptick in the water volume 

recovered at the Buenavista del Cobre mine in Mexico.

We are witnessing a highly volatile copper market. Initial estimates for 2024 called for 

a surplus this year. However, after some producers announced a significant reduction 

Letter to ShareholdersAnnual Report 2023in copper production, market expectations shifted from predictions of a surplus to 

concerns about potential deficits due to low available inventories. In this context, we 

believe copper prices should have good support through 2024.

We  continue  to  focus  on  developing  our  capital  projects  and  controlling  costs  at 

a very competitive level. In 2023, we drove our Pilares project to full capacity and 

initiated  ramp-up  at  the  Buenavista  zinc  concentrator.  For  2024,  we  expect  that 

these projects, combined, will contribute 44,000 tons of copper and 54,000 tons of 

zinc to our production.

2024  production  forecast:  we  expect  to  produce  935,900  tons  of  copper,  or  2.7% 

above  the  production  reported  for  2023.  We  also  expect  to  produce  117,800 

tons of zinc (+79.8%), 20.7 million ounces of silver (+12.2%) and 25,500 tonnes of 

molybdenum, (- 4.2%).

Our  current  capital  investment  program  for  this  decade  exceeds  $15  billion  and 

includes  investments  in  the  Buenavista  Zinc,  Pilares,  El  Pilar  and  El  Arco  projects 

in  Mexico  and  in  the  Tia  Maria,  Los  Chancas  and  Michiquillay  projects  in  Peru. 

7

This  capital  forecast  includes  several  infrastructure  investments,  including  key 

investments to bolster the competitiveness of the El Arco project. 

These  initiatives  heighten  our  optimism  about  the  Company´s  ability  to  continue 

delivering attractive results to our shareholders in coming years.

Southern Copper has been consistently working to promote the well-being of the 

populations in its areas of influence. As part of these efforts, we have implemented 

successful social programs in education, health care and productive development 

to improve the quality of life in the countries in which we operate. Depending on 

characteristics of each zone, we also promote agricultural and livestock activities 

and support initiatives in manufacturing, fishing, and tourism, among others.

On  behalf  of  Southern  Copper  Corporation  Board,  we  express  our  gratitude  to 

all  personnel  for  their  unwavering  effort  and  dedication;  to  our  customers,  for 

their repeated displays of trust and loyalty; and to you, our shareholders, for your 

unwavering support.

Capital Expenditures 
and Exploration 
Program

(Expansion and modernization)

Capital  investments  were  $1,008.6  million  for  2023,  up  6.3%  YoY  to  represent 

41.2% of net income at year-end. Our program to develop the our Company’s full 

production is underway. We are currently developing a new organic growth plan 

whose goal is to increase our copper volume production to 1.3 million tonnes by 

the end of this decade.

For 2024, the Board of Directors approved a capital investment program of $1,103.7 

million. In addition to our ongoing capital maintenance and replacement spending. 

In  general,  the  capital  investments  and  projects  described  below  are  intended 

to  increase  production,  decrease  costs  or  address  social  and  environmental 

commitments.

Our principal capital programs include the following:

MEXICAN PROJECTS:

Buenavista Zinc - Sonora :

This  project  is  located  within  the  Buenavista  deposit,  where  we  have  built  a  new 

concentrator  plant.  This  facility  has  a  production  capacity  of  100,000  tonnes  of 

zinc and 20,000 tonnes of copper per year. When operating, the concentrator will

CONCENTRATOR II PLANT, TOQUEPALA MINE, TACNA, PERU

double the Company’s zinc production capacity and will provide more than 2,000 

jobs on the operating front.

Project  update:  The  capital  budget  for  the  project  is  $439  million,  most  of  which 

has already been invested. Progress is 99%; we have initiated the commissioning 

process.  The  ramping  up  of  the  plant  began  in  the  first  quarter  of  2024  after 

technical adjustments to the concentrator. We expect to produce 54,500 tonnes of 

zinc and 11,900 tonnes of copper in 2024 and an average of 90,200 tonnes of zinc 

and 20,700 of copper per year in the next five years.

Pilares - Sonora: 

Located six kilometers from La Caridad, this is currently an open-pit mine operation 

with  an  annual  production  capacity  of  35,000  tonnes  of  copper  in  concentrate. 

This  project  will  significantly  improve  the  overall  mineral  ore  grade  (considering 

the 0.78% expected from Pilares with 0.29% from La Caridad).

Project  update:  The  budget  for  Pilares  is  $176  million,  of  which  $145  million  has 

been invested. Pilares is fully integrated in our operations and is delivering copper 

ore to the La Caridad concentrator according to plans. Consequently, this will be 

the last time that we report on Pilares as a project.

Annual Report 2023 
 
El Pilar - Sonora: 

This  low-capital  intensity  copper  greenfield  project  is  strategically  located  in  Sonora,  Mexico, 

approximately  45  kilometers  from  our  Buenavista  mine.  Its  copper  oxide  mineralization  contains 

estimated proven and probable reserves of 317 million tonnes of ore with an average copper grade 

of  0.249%.  We  anticipate  that  El  Pilar  will  operate  as  a  conventional  open-pit  mine  with  an  annual 

production capacity of 36,000 tonnes of copper cathodes. This operation will use highly cost efficient 

and environmentally friendly SX-EW technology. The budget for El Pilar is $310 million.

Project update: The results from experimental pads in the leaching process have confirmed adequate 

levels of copper recovery and we are evaluating different options to drive the optimization. The basic 

engineering study has been completed and the Company is engaging in project development and 

onsite environmental activities. Project engineering is being developed by an external engineering 

and technology company. Mine life is estimated at 13 years.

PERUVIAN PROJECTS

Quebrada Honda dam expansion – Tacna:

main and lateral dam; and complementary operational work had culminated.  We 

also installed two cyclone nests for the main dam, which are currently operating. 

Additionally, purchases are pending for equipment for tailings hauling. We intend 

to  build  administrative  facilities  down  the  line.  This  project  has  a  total  budget  of 

$165.0 million, of which we have invested $152.3 million as of December 31, 2023.

Tia Maria - Arequipa: 

This  greenfield  project,  located  in  Arequipa,  Peru,  will  use  state  of  the  art  SX-EW 

technology  with  the  highest  international  environmental  standards  to  produce 

120,000 tonnes of SX- EW copper cathodes per year. The estimated capital budget 

for the project is $1.4 billion. 

The  Company  has  been  consistently  working  to  promote  the  welfare  of  the 

population  of  the  Islay  province.  As  part  of  these  efforts,  we  have  implemented 

successful social programs in education, healthcare and productive development 

to improve the quality-of-life in the region. We have also promoted agricultural and 

livestock  activities  in  the  Tambo  valley  and  supported  growth  in  manufacturing, 

fishing and tourism in Islay. 

We  reiterate  our  view  that  the  initiation  of  construction  activities  at  Tia  Maria 

will  generate  significant  economic  opportunities  for  the  Islay  province  and  the 

Arequipa  region.  Given  the  current  Peruvian  economic  situation,  it  is  crucial  to 

move ahead on projects that will stimulate a sustainable growth cycle. We expect 

to begin the construction phase of the project in the near future. We will make it a 

priority to hire local labor to fill the 9,000 jobs that we expect to generate during Tia 

Maria’s construction. Additionally, from day one of our operations, we will generate 

significant contributions to revenues in the Arequipa region.

Potential projects:

We  have  a  number  of  other  projects  that  we  may  develop  in  the  future.  We 

continuously evaluate new projects based on our long-term corporate objectives, 

strategic  and  operating  fit,  expected  return  on  investment,  required  investment,

reviewed and adjusted to respond to changes in the economy and market conditions.

These projects are:

In Mexico:
El Arco - Baja California: 

This is a world-class copper deposit located in the central part of the Baja California 

peninsula with ore reserves of over 1,230 million tonnes with an average ore grade of 

0.40% and 141 million tonnes of leach material with an average ore grade of 0.27%. 

In Peru:
Los Chancas—Apurimac: 

This  greenfield  project,  located  in  Apurimac,  Peru,  is  a  copper  and  molybdenum 

porphyry  deposit.  Current  estimates  of  indicated  copper  mineral  resources  are  98 

million  tonnes  of  oxides  with  a  copper  content  of  0.45%  and  52  million  tonnes  of 

sulfides with a copper content of 0.59%. The Los Chancas project envisions an open-

pit  mine  with  a  combined  operation  of  concentrator  and  SX-EW  processes  that  will 

produce 130,000 tonnes of copper and 7,500 tonnes of molybdenum annually. The 

estimated  capital  investment  is  $2,600  million  and  the  project  is  expected  to  be  in 

operation in 2030.

Michiquillay Project—Cajamarca: 

In June 2018, Southern Copper signed a contract for the acquisition of the Michiquillay 

project in Cajamarca, Peru. Michiquillay is a world class mining project with inferred 

19

mineral resources of 2,288 million tonnes with an estimated copper grade of 0.43%. 

When developed, we expect Michiquillay to produce 225,000 tonnes of copper per 

year (along with by-products of molybdenum, gold and silver) for an initial mine life 

of more than 25 years and at a competitive cash-cost. We estimate an investment of 

approximately $2.5 billion will be required and expect production start-up by 2032.

THICKENERS OF CUAJONE CONCENTRATOR, MOQUEGUA, PERU

Letter to ShareholdersAnnual Report 2023 
 
Environmental, Social and Governance (“ESG”)

Responsible production is a fundamental axis of our sustainable development strategy, 

which is made up of specific goals and objectives in areas such as water management, 

climate  change  and  mining  waste,  human  talent,  safety  and  health  at  work,  labor 

relations,  development  community,  among  others.  The  Company  has  also  updated 

a  series  of  corporate  policies  related  to  sustainability,  which  are  publicly  disclosed  on 

Grupo  Mexico’s  website:  https://www.gmexico.com/en/Pages/Politicsds.aspx.  These 

policies  are  applicable  to  SCC  and  its  subsidiaries.  These  policies  formalize  our  vision, 

commitments and objectives to promote sustainable development and generate shared 

value for our stakeholders. For more information about our disclosure regarding Human 

Capital Resources, please see the section included in Part I, Item 1 of our Annual Report 

on Form 10-K for the year ended December 31, 2023.

In  2023,  we  continued  to  make  progress  in  our  ESG  (Environmental,  Social  and 

Governance)  performance  by  adopting  best  practices.  The  results  registered  by  S&P 

Global in its Corporate Sustainability Assessment (CSA) indicate that Southern Copper 

Corporation  had  achieved  a  place  among  the  top  10%  of  performers  in  the  mining 

sector  with  a  rating  that  exceeded  the  industry  average  by  100%.  These  results  reflect 

our ongoing commitment to improving our sustainability practices and maintaining the 

Company’s inclusion in the Dow Jones Sustainability Index (DJSI) for the Latin American 

region.  This  year  marks  our  fifth  consecutive  year  in  the  DJSI.  In  2023,  SCC  achieved 

some of the highest scores in the sector for key CSA indicators, including transparency 

and disclosure, occupational safety and health, operations closure, and human capital 

development. 

We obtained a score of 90 out of 100 on CSA’s climate governance index. This attests to 

the progress the Company has made in this area. Additionally, we achieved a score of 

100 in the Task Force on Climate-Related Disclosures (TCDF) category, which focuses 

on  management  and  disclosure  of  financial  risks  and  opportunities  related  to  climate 

21

change.  Additionally,  the  investor-led  Climate  Action  100+  initiative  recognized  our 

efforts  to  develop  an  emissions  reduction  roadmap  and  awarded  us  a  full  compliance 

rating  in  the  Task  Force  on  Climate-Related  Financial  Disclosures  (TCFD)  category. 

Furthermore, the rating agency Sustainalytics reduced the Company’s risk by two levels 

between 2020 and 2023. 

Regarding  the  Climate  Disclosure  Project  (CDP),  we  maintained  a  B  score  for  the 

“Climate change” and “Water security” questionnaires. At the behest of our investors, 

we expanded our responses to include the “Forests” questionnaire. As of the date of 

publication of this report, the score was yet to be available.

The  implementation  and  promotion  of  best  practices  has  helped  SCC  secure  and 

maintain a place on the S&P/BVL Peru General ESG Sustainability Index of the Stock 

Exchange of Lima.

Human Rights
At  SCC  we  are  committed  to  enforcing  the  United  Nations  Guiding  Principles  on 

Business and Human Rights. We have a series of policies and procedures that serve as 

a guide to all employees and suppliers: General Human Rights Policy; Policy of Respect 

for the Rights of Indigenous Peoples and Communities; Diversity, Inclusion and Non-

Discrimination, No Workplace or Sexual Harassment Policy; and the Code of Conduct 

for  Suppliers,  Contractors  and  Relevant  Business  Partners,  which  includes  several 

sections related to human rights. 

The  company  utilizes  a  due  diligence  process  to  monitor  human  rights  to  identify, 

prevent, mitigate or remediate adverse impacts on the human rights of communities. In 

the Mining and Infrastructure divisions, this process has three main components: 

1.  Participatory  Social  Diagnosis  to  allow  the  communities  to  voice  their  concerns 

regarding human rights,

2.  Social Management Plans that define actions to address those concerns, and

3.  Community Care Service (SAC), a tool that was designed with guidance from the 

United Nations High Commissioner for Human Rights (Mexico Office); communities 

can  use  this  instrument  to  immediately  communicate  their  concerns  to  the 

Company.

The Company also has a due diligence process in place to protect the human rights 

of  employees  (both  the  Company  and  contractors).  Work  environment  surveys,  the

Complaint Line and supplier due diligence are the tools the company uses to comply with the 

commitments included in the General Human Rights Policy. Currently, we are implementing a 

Diversity and Inclusion Strategic Plan, which focuses primarily on training; review of contracting 

processes; and physical changes in work areas.

Diversity, Equity and Inclusion (DEI)
Our vision of DEI is to ensure that our people always feel included, welcomed and valued for 

their personal and professional contributions. This vision is based on our core values of respect, 

honesty and responsibility.

In  keeping  with  our  Code  of  Conduct  and  Human  Rights  Policy,  our  goal  is  to  (i)  build  an 

organizational culture of total equality and well-being, focusing on diversity, inclusion and non-

discrimination, (ii) increase the sensitivity, knowledge and skills of our leaders and employees to 

build diverse and inclusive teams and promote a culture of respect, and (iii) extend this culture 

to the communities in which we operate. 

Based on the results of a DEI survey in Mexico and Peru, we aligned our diversity and inclusion 

2020-2023 Strategic Plan with five strategic initiatives:

1.  Awareness  campaigns,  training  and  communication  on  diversity,  inclusion  and  non-

discrimination. 

2. 

Incorporate  a  gender  equality  and  diversity  approach  into  our  human  resources  policies 

and procedures (focused both on hiring and retention). 

3.  Physical modifications at our operations for the inclusion of women. 

4.  Promote diversity and equal opportunities in our neighbor communities. 

5.  Define  specific  processes  on  awareness,  prevention  and  handling  potential  incidents  of 

23

sexual and/or workplace harassment. 

In 2022, we disclosed our Policy on Diversity, Inclusion, Non-Discrimination, and Zero Tolerance 

for  Workplace  or  Sexual  Harassment  for  Grupo  Mexico  and  the  Mining  Division.  The  latter 

describes the reporting mechanisms available in Mexico, Peru and the United States, and the 

protection offered to whistleblowers. In 2023, we provided training about diversity and inclusion

to  more  than  5,700  employees.  Our  goal  is  to  increase  women’s  participation  in 

the organization by 2% a year. We grew our female workforce from 1,090 to 1,221, 

which represents an increase of 12% in our female headcount year-over-year. We 

also increased the number of females who hold Leadership positions by 12%. This 

year,  34%  of  our  female  workforce  holds  a  STEM  position  (Science,  Technology, 

Engineering, Mathematics).

We  now  have  a  better  understanding  of  our  diversity  distribution,  which  helps  us 

design efforts for each group and advance towards inclusion.

Code of Ethics
We certify our employees in our Code of Ethics yearly. Every employee, including 

new hires, signs and commits to adhering to an agreement. The Code of Ethics is 

the tool we use to infom and guide employees regarding our expectations for legal, 

professional and ethical conduct in both in our business dealings and  interpersonal 

relationships.

Community Outreach
We  have  implemented  several  sustainable  development  policies  designed  to 

integrate  the  Company’s  operations  with  the  local  communities  in  our  areas  of 

influence. Some of the relevant policies include: the General Policy for Sustainable 

Development;  a  Community  Development  Policy;  a  General  Policy  of  Respect  for 

the  Rights  of  Indigenous  Peoples  and  Communities,  and  a  Human  Rights  Policy, 

which can be consulted on the Grupo Mexico website and apply in their entirety at 

the Southern Copper Corporation level.

25

These policies focus on creating permanent and positive relationships to generate 

optimal  social  conditions  and  promote  sustainable  development  in  the  areas  of 

influence. We continue to invest signficantly in community programs. For additional 

information about our community programs, refer to Corporate Social Responsibility 

in Note 13 “Commitments and contingencies” to the consolidated financial statements, 

in our 2023 Form 10-K.

In  2023,  SCC  was  recognized  by  the  state  agency  ProInversion  for  a  Drinking  Water 

and Rural Sanitation Program in Yacango town, Torata district. This project benefits 137 

families through an investment of $2.8 million. Similarly, in Mexico, we have invested in 

water distribution improvements in Nacozari and Cananea to benefit more than 53,800 

residents.

Additionally,  Youth  Orchestras  promoted  by  SCC  were  recognized  by  Mexican 

Polymetallic  Seminar.  These  orchestras  support  1,646  students  in  Mexico  and  Peru.  

SCC, with the support of the State Institute of Culture, held the first exhibition of work 

from  its  Itinerant  Documentary  Workshops  at  the  Cineteca  in  the  State  in  Sonora, 

Mexico. At this event, 17 original short films, which were produced by some of the 747 

workshop participants, were on show.

Annual Report 2023 
Community Development Model 
SCC  seeks  to  improve  the  quality  of  life  in  the  communities  around  its 

operations by engaging in responsible management. SCC has developed a 

model where people are agents of their own development.

Our Community Development Model approaches developing relationships 

with communities through three specific components:

Good
Neigbors

Ensuring that the operations coexist in a positive 
and healthy manner in the places where we 
operate.

Economic
Development

Sharing the wealth generated by the operations 
with the community by creating or regenerating 
the social fabric and strengthening the same to 
consequently increase economic value.

Human 
Development

Strengthen the capacities the members of 
the communities in which we operate; these 
individuals are the main drivers of development 
at the personal, family and environmental levels.  

Good Neigbors 

We seek to generate a positive and healthy coexistence with our neighbors, 

through  close,  open  and  constant  communication  channels  with  the 

communities.  

Economic Development 

Through  training  and  skill-building  programs,  as  well  as  investments  in 

infrastructure, we contribute to strengthening the productive and economic 

27

capacities of communities. 

Human Development 

To generate trust relationships and co-responsibility with communities, our 

Casa Grande model rolls out programs at community centers; these efforts 

focus on education, health, culture and the environment.

CUAJONE MINE, MOQUEGUA, PERU

This  model 

is  known  as  “Casa  Grande”,  and 

it  has  been 

implemented through the following tools: 

•  28 Community Development Centers (13 in Mexico and, 

15 in Peru).- Open Houses for communities that offer courses 

and  workshops  to  promote  development  through  programs 

and  projects  that  focus  on  education,  health,  culture  and 

environmental protection. 

•  Participatory  Diagnostics.  -  We  respect  the  voice  of  the 

community  and  work  with  local  populations  to  conduct 

community diagnoses to identify needs and expectations and 

prioritize work through the Casa Nuestra model. 

•  Community  Committees.-  Led  by  volunteers  from  the 

community  and  Company  employees,  who  collaborate  to 

assess proposals for sustainable projects. 

•  Seed  Capital.-  AWe  call  on  communities  to  present  their 

initiatives.  SCC’s  primary  axes  are  education  and 

the 

environment, which are complemented by initiatives relative 

to health, safety and productivity..

Annual Report 2023 
 
 
Children and young people are our priority, and we strive to ensure a better future for 

new generations. Community projects are assessed by committees that are comprised 

of both SCC employees and local personalities and the focus is on promoting dialogue 

and citizen participation. 

•  Productive  Projects.-  Projects  that  transform  community  lives  by  generating 

productive skills. 

•  Our team of experts uses this model to materialize the Company’s initiatives with the 

participation of SCC volunteers and the community. Meetings are held at ommunity 

centers to generate shared value.

•  SCC’s  social  team  and  volunteers  from  neighboring  communities,  an  important 

number  of  projects  were  developed.  In  2023,  we  conducted  4,977  activities,  258 

programs and projects with 209 community and corporate volunteers. Through our 

Seed  Capital and productive  projects, we helped create development  generators 

and promoted the participation of proactive leaders who work to enhance the well-

being of their communities.  

Education and Entrepreneurship  
Another  way  of  contributing  to  people’s  development  is  by  providing  training  and 

education  opportunities  to  children  and  young  people  in  neighboring  communities 

at the elementary, secondary, vocational or university levels. At our mining operations 

in Mexico and Peru, we contribute to community education through 11 schools that 

are sponsored by the Company and which offer scholarships to employees and their 

families for different levels of study. These company-sponsored schools are home to 

29

3,418  students  from  the  preschool  to  high  school  levels.  Most  students  are  children 

of  employees  or  community  members.  In  addition,  we  have  complemented  school 

subjects with programs for students and parents.

As part of our ongoing commitment, the company is actively expanding 

educational infrastructure in Peru to benefit the community under the 

law of Social Investments for Taxes (Obras por Impuestos). This effort 

includes  the  creation  of  five  high  performance  schools  (COAR)  for 

1,500 students, to strengthen their capacities as outstanding students 

in the public sector. Two schools are currently under construction, in 

the regions of Moquegua and Tacna. SCC is the main private investor 

in educational infrastructure in Peru.

In  Mexico,  we  renovated  two  community  centers  (called  Casa 

Grande) in Santa Barbara, Chihuahua and Charcas, San Luis Potosi. 

These  facilities  will  serve  an  additional  21,000  people,  who  will  use 

these  spaces  for  learning  and  network.  Both  centers  are  equipped 

with a library, recreational area, audiovisual room, computer centers, 

spaces  for  physical  activities,  areas  for  temporary  exhibitions  and 

green spaces.

Infrastructure and Services 
In  2023,  SCC  trained  2,087  people  from  our  communities:  833  for 

employment, 1,145 in regional vocational and productive skills, and 

109 from local companies to support small and medium-sized mining 

suppliers.  Additionally,  SCC  increased  97%  social  infrastructure  in 

year-over-year. In Mexico, $35.9 million was invested to improve water 

infrastructure  in  the  Cananea  and  Nacozari  communities.  In  Peru, 

$45.7  million  was  invested  in  social  infrastructure  via  a  wastewater 

treatment plant (WWTP) in Ilo.

environment.  We  operate  in  alignment  with  our  environmental 

management system to:

1.  Plan, design, build and operate our facilities with a preventive 

approach throughout their life cycle.

2.  Reduce the risks and damage that our activities may imply for 

the environment.

3. 

Improve  our  environmental  performance  by  going  beyond 

environmental compliance.

4.  Reduce our carbon footprint and contribute to an environment 

resilient to climate change.

5.  Conserve  water  by  using  efficient  processes  during 

production  while  contributing  to  ensuring  that  water  is 

available in the basins near our operating areas.

6.  Promote the efficient use of energy.

7.  Contribute  to  the  conservation  of  biodiversity  and  the 

environment,  which  generates  ecosystems  with  a  positive

8.  Add  value  to 

its  customers,  suppliers,  society  and  the 

environment through all of our activities. 

These lines of action, which entailed an investment of US$290.7 

million  in  2023,  were  rolled  out  within  the  framework  of  the 

Annual Report 2023 
 
 
 
international  and  local  certifications  that  our  operating  units 

have  in  the  two  countries  where  we  are  present.  In  2023,  all  of 

SCC’s  systems  were  certified  ISO  14001:2015  certification  for 

environmental  management  systems,  which  attests  to  both  our 

employees’ commitment and the effectiveness of the transversal 

application of environmental practices.

Additionally,  we  continue  to  advance  in  processes  to  certify 

responsible  mining  production.  We  received  The  Copper  Mark, 

The Zinc Mark and The Molybdenum Mark seals in the La Caridad 

mine, the Sonora Metallurgical Complex and the San Luis Potosi 

Zinc Refinery. Additionally, SCC began the process to certificate 

Buenavista del Cobre mine in Sonora and our three mining units 

in Peru (Cuajone, Toquepala and Ilo).  

Climate Change 

SCC recognizes the importance and urgency of addressing climate 

change  and  is  committed  to:  the  goals  of  the  Paris  Agreement 

on  climate  change;  conserving  the  environment;    minimizing 

environmental 

footprint  of  our  operations;  and  efficiently 

managing  risks  and  opportunities  related  climate  change.  We 

33

recognize climate change is likely to impact our strategy in several 

ways, and we aim align with global business trends that increasingly 

demand  products  with  lower  carbon  footprints.  Our  priority  is  to 

responsibly improve use of natural resources while complying with 

legal standards for prevention, mitigation, control and remediation 

of environmental impacts.

The Company is committed to continually improving its management 

of  the  aforementioned  issues,  which  is  why  it  has  initiated  a  multi-

year process to align its disclosures on climate change with TCFD 

recommendations.  As  a  result,  beginning  in  2020,  Grupo  Mexico’s 

Sustainable  Development  Report  included  sections  on  climate-

related  risks  and  opportunities,  and  more  detailed  information 

about  new  short,  medium  and  long  term  Scope  1  and  2  climate 

targets,  strategy  and  governance  mechanisms,  as  well  as  new 

emissions and energy metrics informed by SASB standards. In our 

2023  Sustainability  Development  Report,  we  will  include  Scope  3 

targets and preliminary capital allocation figures on decarbonization 

projects. The report can be accessed at https://www.gmexico.com/

en/Pages/development.aspx. 

We  are  referring  our  investors  to  Grupo  Mexico’s  internet  site  for 

details  on  the  aforementioned  initiatives  for  informative  purposes 

only. We do not intend for this internet link to be an active link or to 

otherwise  incorporate  the  contents  of  the  website  into  this  Report 

on Form 10-K.

Additionally,  since  2019,  SCC  has  been  participating  in  the  S&P 

Global CSA evaluation, where we obtained a score of 90 out of 100 

in the climate governance index. This attests to the progress that the 

Company has made in this area. Additionally, we achieved a score of 

100 in Task Force on Climate-Related Disclosure (TCDF) category,

identifying  and  treating  opportunities  related  to  climate  change. 

The  investor-led  initiative,  Climate  Action  100+,  awarded  us  a  full 

compliance rating in the TCFD category in recognition of our efforts 

to create a roadmap for emission reduction.

Since  2016,  SCC  has  participated  in  CDP’s  annual  evaluation  on 

Climate  Change  (previously  known  as  Carbon  Disclosure  Project). 

In  2023,  Grupo  Mexico’s  achieved  a  “B”  rating,  the  third  best  on 

evaluation  scale  in  both  questionnaires  on  “climate  change”  and 

“water security.” Progress in managing these issues has positioned 

SCC above the average scores registered for the mining sector and 

the North American region: 

•  Provide  products  and  services  that  support  transition  to  low 

carbon economies

•  Reduce carbon footprint of the organization 

•  Increase the resilience of our operations by addressing potential 

climate change effects in surrounding communities 

•  Align SCC with international best managing practices.

To reduce its carbon footprint, SCC is betting on energy diversification 

by  focusing  on  greater  reliance  on  clean  and  renewable  energy 

supplies. Our Mexican operations have mitigated a portion of their 

35

indirect  greenhouse  gas  emissions  by  consuming  clean  energy 

supplied by SCC subsidiaries, which generate electricity from high-

efficiency combined cycle plants and a wind farm. In Peru, 100% of 

the  electricity  we  consumed  in  2023  was  supplied  by  renewable 

energy sources through Clean Energy Certificates.

In addition to generating and consuming energy from renewable 

sources  and  cleaner  fuels,  we  also  implement  best  practices 

to  enhance  energy  efficiency  at  our  operations.  These  efforts 

entail  improvements,  redesign,  conversion  and  adaptation  of 

equipment; rational use of resources; and training for personnel 

to  bolster  operating  performance.  For  example,  in  Sonora,  we 

take  advantage  of  smelter  gases  in  the  heat  recovery  boiler  to 

feed energy cogeneration.

Climate-related transition risks: 

SCC  recognizes  that  climate  change  has  the  potential  to 

generate transition/adaptation risks for the Company associated 

with, for instance, technological and other operational changes; 

changing market trends; or credit risks. Based on its assessment, 

SCC does not believe at this time that said risks have had or will 

have  a  material  impact  on  its  business,  financial  condition  or 

results  of  operation.  The  impacts  of  climate  change  policy  and 

regulatory changes in Mexico and Peru are described below.

Mexican Operations
Several taxes are applicable to SCC’s mining operations in Mexico. 

These taxes range from $2.5/tCO2 to $12.5/tCO2 approximately. 
At the federal level, there is a tax on fuel imports, while at the state 

level, taxes for this concept apply in the States of Baja California, 

San Luis Potosi and Zacatecas. Additionally, there is an emissions 

trading scheme (ETS) that completed its pilot phase in 2022 and 

is officially operational. 

Currently, 

requirements  associated  with 

this  scheme  are 

applicable only to the Metallurgical Complex and the Lime Plant,

both located in the state of Sonora, which generate annual levels of GHG emissions 

that surpass the threshold of 100,000 tCO2 per year contemplated in scheme. These 
business units must report and verify their emissions once a year, at average costs 

less than $6,000 USD per unit.

SCC units located in Mexico that emit more than 25,000 tons of CO2 equivalent per 
year (all our units except the Guaymas Terminal and the Taxco underground mine) 

must  report  their  emissions  to  the  National  Emissions  Registry  (RENE)  each  year 

and verify emissions reported every three years. Our total annual compliance costs 

related to climate change regulations in Mexico were less than $30,000 for each of 

the three years ended December 31, 2023; this amount had no material impact on 

the Company.

Peruvian Operations 
On  April  17,  2018,  the  Peruvian  government  enacted  Law  No.  30754,  which 

establishes  a  Climate  Change  Framework.  This  law  has  declared  that  promoting 

public and private investments to manage climate change constitutes a matter of 

national interest. The law proposes creating an institutional framework to address 

climate  change  in  Peru  and  outlines  new  measures,  with  a  particular  focus  on 

climate  change  mitigation.  The  aforementioned  measures  include  provisions 

related  to  increasing  carbon  capture  and  the  use  of  carbon  sinks;  afforestation 

and  reforestation  practices;  changes  in  land  use;  and  sustainable  transportation 

systems,  solid  waste  management,  and  energy  systems.  This  is  the  first  climate 

change  framework  law  in  Latin  America  that  incorporates  obligations  of  the  Paris 

Agreement. The Regulation of this law was enacted by Supreme Decree 013-2019, 

38

which  was  published  on  December  31,  2019,  and  is  applicable  to  all  Peruvian 

institutions and organizations. Peruvian regulations are expected to be extended to 

non-governmental entities in the future; however, for the Company’s operations in 

Peru, there are no mechanisms in place for carbon pricing.

At SCC, we recognize that climate change is impacting market trends, which reflect 

a growing demand for goods with lower carbon footprints or for materials that help 

Annual Report 2023 
reduce emissions at their point of origination. Large copper consumers will more than 

likely increasingly seek to acquire low or zero-emission products to achieve their own 

GHG emission reduction targets. Adapting to this trend inadequately or with insufficient 

speed might result in reputational risks or loss of market opportunities for SCC. Based 

on these assessments, the Company does not believe that these impacts have been or 

are material at this time.

The  Company  will  continue  evaluating  how  climate-related  risks  could  affect  its 

financial  interests  and  will  define  appropriate  mitigation  and  adaptation  responses 

as  necessary.  The  Company  will  also  continue  to  assess  how  variations  in  global 

and national GHG emissions may increase the regulatory burden as well as demand 

for  low-carbon  or  carbon-free  products  from  customers,  investors,  and  stakeholders 

in  general.  Recently,  investors  have  been  asking  the  Company  to  disclose  its  GHG 

emission reduction goals, in alignment with the Paris Agreement to keep the increase 

in global to below 2 degrees Celsius. The Company is currently defining these targets 

and aims to publicly disclose the same in forthcoming reporting.

Climate - Related Opportunities 

In accordance with the goals of the Paris Agreement on climate change, global GHG 

emissions reductions must be achieved to contain global warming below 1.5 degrees 

Celsius above the pre-industrial average temperature. Copper is a critical component 

for many technologies required for transition to low-carbon economies, including wind 

and  solar  photovoltaic  power  generation,  electric  vehicles,  power  grids,  and  more. 

Consequently,  the  demand  for  copper  is  expected  to  increase  significantly,  which 

could boost copper prices and positively impact the Company’s income.

Additionally,  we  believe  that  the  cost  of  renewable  electricity  generation  will  move 

closer  to  competing  with  the  costs  of  conventional  power  plants.  This  will  offer 

opportunities to reduce both operating costs and GHG emissions.

As  one  of  the  world’s  largest  copper  producers,  we  believe  that  the  implications  of 

climate change could benefit SCC’s reputation as stakeholders increasingly recognize 

39

the  vital  role  that  copper  plays  in  helping  societies  migrate  to  low  carbon 

economies.  However,  we  realize  that  this  is  conditional  upon  the  Company’s 

commitment  to  helping  achieve  the  objectives  of  the  Paris  Agreement  and 

its  ability  to  demonstrate  clear  and  sustained  progress  in  decarbonizing  its 

operations, as required by this agreement.

With  these  actions,  and  others,  SCC  confirms  the  commitment  to  reduce 

its  carbon  footprint,  address  its  implications  and  perform  as  a  sustainable 

company, both nationally and internationally, improving its competitiveness and 

contributing to the transition towards low-carbon economies.

In 2024, we will continue to identify more financial impacts related to the climate 

risks and opportunities our company will face in the future.

Biodiversity 

Southern Copper Corporation implements actions to generate positive impacts, 

reaffirming its commitment to the environment and biodiversity. To comply with 

this  commitment,  which  is  detailed  in  the  Company’s  Environmental  Policy, 

we have developed action plans for biodiversity management that are aligned 

with  the  Good  Practices  for  Mining  guide  and  Biodiversity  published  by  the 

International  Council  of  Mining  and  Metals  (ICMM).  These  plans  improve  the 

Company’s  ability  to  implement  effective  prevention  and  mitigation  measures 

and contribute to the preservation and improvement of the environment in both 

operating areas and surrounding communities.

We are the company with the largest productive capacity of trees in the mining 

industry in Mexico. In our operating units we have 7 nurseries and greenhouses 

that  in  2023  produced  5.6  million  plants,  part  of  which  was  destined  for 

reforestation and rehabilitation of ecosystems, including protected natural areas 

near our operations.

Annual Report 2023As part of our effort to conserve biodiversity, we have a 174-hectare Environmental 

Management  Unit  (UMA),  which  has  been  conditioned  to  replicate  -through 

enclosures-  threatened  and  endangered  species  such  as  the  Mexican  Gray  Wolf 

and Gould’s Turkey among others, that are part of this important program.

SCC’s  UMA  in  Mexico  is  located  in  a  strategic  area  to  boost  Mexican  Gray  Wolf 

reproduction. Since 2013, SCC has been part of the US-Mexico Binational Program 

to  Recover  the  Mexican  Gray  Wolf.  To  date,  it  has  housed  62  specimens  of  the 

Mexican wolf and has delivered 23 cubs in its facilities. In a coordinated effort with 

Mexican  and  United  States  authorities  through  the  Binational  Mexican  Gray  Wolf 

Recovery  Program,  27  specimens  have  been  reintroduced  to  sites  where  this 

species originally lived.

In  March  2023,  the  Environmental  Management  Unit  in  Buenavista  del  Cobre 

obtained  certification  from  the  Wildlife  Habitat  Council,  for  our  contribution  to 

preventing  extinction  of  Mexican  gray  wolf.  Thanks  to  our  actions,  this  species, 

which  was  once  extinct  in  the  wild,  now  has  populations  in  its  natural  habitat  in 

Mexico.  We  will  continue  working  society  hand  and  the  authorities  for  common 

good in the regions where we operate.

Our  remediation  program  in  Ite  Bay,  in  Tacna,  with  an  area  of  1,600  hectares, 

has  resulted  in  the  largest  wetland  with  the  greatest  diversity  of  waterfowl  on 

the  country’s  coast,  and  has  also  become  a  focus  of  tourist  attraction  that  favors 

economic development.

Water care 

Water  constitutes  the  most  important  input  for  our  mining  operations,  which  is 

why  we  have  developed  projects  to  guarantee  the  sustainability  of  this  resource. 

41

 
These initiatives focus on ensuring efficient water use; promoting 

water  reuse;  and  reusing  water  discarded  by  third  parties.  At 

some  of  our  units,  such  as  San  Luis  Potosi,  we  use  specially 

treated municipal wastewater to ensure that more fresh water is 

available for the local population. Efficient wateruse and savings 

programs rely on pumping systems to recover water from tailings 

and  thickeners  and  use  closed  circuits  to  recirculate  the  total 

volume of processed water. In 2023, more than 74% of total water 

consumption at our mining operations utilized recovered water, 

which attests to our good management.

Results of 
Operations 

Years ended December 31, 2021, 2022 and 2023.

Our  net  income  attributable  to  SCC  in  2023  was  $2,425.2,  compared  to  2022  was 

$2,638.5  million  and  $3,397.1  million  in  2021.  SCC’s  net  income  attributable  to  SCC 

decreased $213.3 million (8.08%), which was partially mitigated by an uptick in sales 

volumes for copper and higher prices for by-products. 

The Company presents its operating cash costs with and without the revenues of its 

by-products (molybdenum, silver, sulfuric acid, etc.). It excludes the cost of purchases 

of third-party metal, depreciation, amortization and depletion, exploration, provisions 

for  employee  profit  sharing,  other  non-recurring  items  and  royalty  charges  from  its 

operating cash cost calculation.

The  Company’s  operating  cash  cost  per  pound  of  copper  produced,  as  previously 

defined, for the three years ended December 31, is as follows:

Annual Report 2023 
 
 
 
As seen in the table above, our per pound cash cost before by-product revenues 

in  2023  was  8.4%  higher  when  compared  with  2022.  This  result  was  mainly 

attributable to an increase in production costs. Our cash cost per pound net of 

by-product revenues for 2023 was 32.6% above the figure for the same period 

of 2022 and was mainly attributable to an increase in the production cost of 

16.2 cents per pound and a reduction of 8 cents in by-product revenue credits.

Net sales: 
2023-2022:  Net  sales  in  2023  totaled  $9,895.8  million,  which  represents  a 

slight decrease compared to 2022 net sales of $10,047.9 million. This decrease 

was  driven  by  lower  copper  (-3.8%  -  LME)  and  zinc  (-24.1%)  prices,  along 

with  a  reduction  in  the  sales  volumes  of  silver  (-4.3%)  and  zinc  (-1.4%).  This 

impact was partially offset by increased sales volumes for copper (+2.2%) and 

molybdenum (+2.3%) and by better prices for molybdenum (+27.5%) and silver 

(+7.6%).  Net sales in 2023 were adversely affected by downward adjustments 

of  $406.0  million  after  sales  were  provisionally  priced  due  to  decreases  in 

metal prices.

2022-2021: Net sales in 2022 were $10,047.9 million in 2021 were $10,934.1 

million, which represented a decrease of $886.2 million. This 8.1% reduction 

was driven primarily by a decrease in sales volume copper (-6.5%), silver (-1.9%) 

45

and  molybdenum  (-13.4%),  which  was  driven  primarily  by  lower  production 

and secondarily by a drop in prices for copper (-5.4%) and silver (-13.6%). The 

aforementioned was partially offset by an increase in the sales volume of zinc 

(+10.5%)  and  by  a  rebound  in  the  prices  of  molybdenum  (+20.0%)  and  zinc 

(+16.2%).

Prices: 
The profitability of our operations is dependent on, and our financial performance 

is  significantly  affected  by,  the  international  market  prices  for  the  products  we 

produce, and for copper, molybdenum, zinc and silver in particular. Sales prices for 

the Company’s metals are mainly pegged to the prices quoted on the London Metal 

Exchange  (LME)  and  The  New  York  Commodity  Exchange  (COMEX)  or  to  those 

published in the Platt’s Metals Week for dealer oxide mean prices for molybdenum.

Compromises and 
Contingencies 

Environmental matters 

The Company has established comprehensive environmental conservation programs 

at  its  mining  facilities  in  Peru  and  Mexico.  The  Company’s  environmental  programs 

include water recovery systems to conserve water and minimize the impact on nearby 

streams; reforestation programs to stabilize the surface of the tailings dams; and use of 

scrubbing technologies in our mines to reduce dust emissions, among others.

Environmental capital investments in years 2021, 2022 and 2023, were as follows (in

Mexican operations
The  Company’s  operations  are  subject  to  applicable  Mexican  federal,  state  and 

municipal environmental laws, to Mexican official standards, and to regulations for the 

protection  of  the  environment,  including  regulations  relating  to  water  supply,  water 

quality, air quality, noise levels and hazardous and solid waste.

Annual Report 2023 
 
 
 
The  principal  legislation  applicable  to  the  Company’s  Mexican  operations  is  the 

Federal  General  Law  of  Ecological  Balance  and  Environmental  Protection  (the 

“General Law”), which is enforced by the Federal Bureau of Environmental Protection 

(“PROFEPA”).  PROFEPA  monitors  compliance  with  environmental  legislation  and 

enforces Mexican environmental laws, regulations and official standards. It may also 

initiate  administrative  proceedings  against  companies  that  violate  environmental 

laws,  which  in  the  most  extreme  cases  may  result  in  the  temporary  or  permanent 

shutdown of non-complying facilities, the revocation of operating licenses and/or 

other sanctions or fines. 

In 2011, the General Law was amended to provide an individual or entity the ability 

to  contest  administrative  acts,  including  environmental  authorizations,  permits  or 

concessions granted, without the need to demonstrate the actual existence of harm 

to the environment, if it can be argued that harm may in fact be caused. Additionally, 

amendments to the Civil Federal Procedures Code (“CFPC”) were enacted in 2011 

and  established  three  categories  of  collective  actions  under  which  a  group  of  30 

or  more  individuals  can  be  considered  sufficient  to  prove  a  “legitimate  interest” 

to  file  civil  actions  for  injuries  arising  out  of  alleged  violations  of  environmental, 

consumer  protection,  financial  services  and  antitrust  laws.  The  group  can  seek 

restitution, economic compensation for alleged injuries or move to halt the activities 

that allegedly caused the injuries in question. Amendments to the CFPC may result 

in  more  litigation,  with  plaintiffs  seeking  remedies,  including  suspension  of  any 

activities alleged to cause harm.

In 2013, the Environmental Liability Federal Law was enacted. The law establishes 

general  guidelines  for  actions  considered  likely  to  cause  environmental  harm. 

If  a  possible  determination  regarding  harm  occurs,  environmental  clean-up  and 

remedial  actions  sufficient  to  restore  the  environment  to  a  pre-existing  condition 

49

must  be  taken.  If  restoration  is  not  possible,  compensation  measures  should  be 

provided. Criminal penalties and monetary fines can be imposed under this law.

In February 2019, the Supreme Court of Mexico confirmed the constitutionality of an 

ecological tax on extractive activities carried out in the state of Zacatecas, which taxes 

environmental remediation activities, emissions of certain gases into the atmosphere, 

emissions of substances contaminants to soil or water and the storage of waste within 

the territory of this state. The Company is evaluating the potential impact of this new 

environmental standard on its financial position.

Climate change: Several taxes are applicable to the Company’s mining operations in 

Mexico, including federal and state fossil fuel taxes, and the requirements associated 

with Mexico’s emission trading scheme. These taxes range from $US9/tCO2 to $US18/

tCO2 in 2023, approximately. These regional taxes, which are in addition to a federal tax 

on fuel imports, are applicable in the States of Baja California, Zacatecas and San Luis 

Potosi. In addition, Mexico’s emission trading (ETS) currently applies to the Company, 

but solely through two business units, the metallurgic and lime plants in Sonora, which 

both  generate  annual  GHG  emissions  levels  above  the  threshold  of  100,000  tCO2 

per  year  contemplated  by  the  scheme.  Every  year,  these  units  are  required  to  report 

and  verify  emissions  with  average  costs  of  less  than  $6,000  per  unit.  Units  that  emit 

more than 25,000 tonnes CO2 equivalent per year (all our Mexican units) are required 

to  report  their  emissions  to  the  National  Emissions  Registry  (RENE)  on  a  yearly  basis 

and  must  verify  reported  emissions  every  three  years.  The  total  expense  associated 

with ensuring annual compliance with climate change regulations in Mexico was not 

material to the Company.

On  May  09,  2023,  Mexican  Congress  approved  several  changes  to  the  Mining  Law, 

50

National  Waters  Law,  the  General  Law  of  Ecological  Balance  and  Environmental 

Protection, and the General Law for the Prevention and Integral Management of Waste, 

all of which were effective immediately. The main changes entailed reducing mining 

concession terms from 50 to 30 years; new restrictions and conditions on water use; 

requirements  to  provide  guarantees  for  closure  and  remediation  of  operations;  and 

a  requirement  to  contribute  5%  of  net  earnings  to  indigenous  communities  for  new 

projects and significant changes to exploration rules.

Annual Report 2023 
 
We are the mining company with 
the largest productive capacity 
of trees (Mexico).

These amendments to the law have been challenged and are being reviewed by the 

Supreme Court. The company is not expecting any negative impacts on its operations.

Peruvian operations
The Company’s operations are subject to applicable Peruvian environmental laws and 

regulations. The Peruvian government, through the Ministry of Environment (“MINAM”) 

conducts  annual  audits  of  the  Company’s  Peruvian  mining  and  metallurgical 

operations. Through these environmental audits, matters relating to environmental and 

legal compliance, atmospheric emissions, effluent monitoring and waste management 

are reviewed. The Company believes that it is in material compliance with applicable 

Peruvian  environmental  laws  and  regulations.  Peruvian  law  requires  that  companies 

in  the  mining  industry  provide  assurances  for  future  mine  closure  and  remediation. 

In  accordance  with  the  requirements  of  this  law,  the  Company’s  closure  plans  were 

approved by MINEM. See Note 10 “Asset retirement obligation” for further discussion 

of this matter. 

Air Quality Standards (“AQS”): In June 2017, MINAM enacted a supreme decree which 

defined  new  AQS  for  daily  sulfur  dioxide  in  the  air.  As  of  December  31,  2023,  the 

Company maintains the daily average level of µg/m3 of SO2, below the requirement 

of the AQS.

In November 2023, MINAM enacted a new AQS for Cadmium, Arsenic and Chromium 

in  particulate  matter  less  than  ten  microns  (PM10).  A  review  of  the  Company´s 

51

chemical  monitoring  results  has  determined  that  the  Company´s  operations  will  not 

be significantly impacted by the new standards and concentration values in place. Our 

results are expected to continue to fall below regulatory AQS. 

Soil  Environmental  Quality  Standards  (“SQS”):  In  2013,  the  Peruvian  government 

enacted Soil Quality Standards. In accordance with the regulatory requirements of the 

law,  the  Company  prepared  Soil  Decontamination  Plans  (“SDP”)  for  environmentally 

impacted  sites  at  each  of  its  operation  units  (Toquepala,  Cuajone  and  Ilo)  with  the 

assistance of consulting companies. The costs of these SDPs are not material, either 

individually or in aggregated form, for the financial statements of the Company.

Climate change: On April 17, 2018, the Peruvian government enacted Law N. 30754, 

which promotes public and private investments in climate change management and 

establishes a Climate Change Framework. The law proposes creating an institutional 

framework to address climate change in Peru and outlines new measures for climate 

change mitigation, such as provisions to address an increase in carbon capture and 

use  of  carbon  sinks;  afforestation  and  reforestation  practices;  land  use  changes; 

sustainable systems of transportation, solid waste management, and energy systems. 

This climate change framework law incorporates obligations from the Paris Agreement. 

Supreme  Decree  013-2019  published  on  December  31,  2019,  enacted  statutory 

regulations, which are applicable to all Peruvian institutions and agencies. It is expected 

that  additional  Peruvian  regulations  will  be  applicable  to  non-governmental  entities. 

However,  no  carbon  pricing  mechanism  is  currently  applicable  to  the  Company’s 

operations in Peru.

The Company believes that all its facilities in Peru and Mexico are in material compliance 

with environmental, mining and other applicable laws and regulations. The Company 

also  believes  that  continued  compliance  with  environmental  laws  of  Mexico  and 

Peru will have no material adverse effects on the Company’s business, properties, or 

operating results.

General 
Information 

Information related to its constitution and inscription in the Public Registry: 

Southern  Copper  Corporation  (SCC)  is  one  of  the  largest  integrated  copper 

producers  in  the  world.  We  produce  copper,  molybdenum,  zinc,  silver,  lead  and 

other by-products. All our mining, smelting and refining facilities are located in Peru 

and in Mexico and we conduct exploration activities in those countries and in Chile, 

Ecuador and Argentina. Our operations make us one of the largest mining companies 

in  both  Peru  and  Mexico.  We  are  one  of  the  largest  copper  mining  companies  in 

the world. We were incorporated in Delaware in 1952 and have conducted copper 

mining operations since 1960. Since 1996, our common stock has been listed on 

both the New York and the Lima Stock Exchanges.

Our Peruvian copper operations involve mining, milling and flotation of copper ore 

to  produce  copper  concentrates  and  molybdenum  concentrates;  the  smelting  of 

copper concentrates to produce anode copper; and the refining of anode copper to 

produce copper cathodes. As part of this production process, we produce significant 

54

amounts of molybdenum concentrate and refined silver. We also produce refined 

copper  using  SX/EW  technology.  We  operate  the  Toquepala  and  Cuajone  mines 

high  in  the  Andes  Mountains,  approximately  860  kilometers  southeast  of  the  city 

of  Lima,  Peru.  We  also  operate  a  smelter  and  refinery  west  of  the  Toquepala  and 

Cuajone mines in the coastal city of Ilo, Peru.

Annual Report 2023 
 
 
Our Mexican operations are conducted through our subsidiary, Minera Mexico S.A. 

de  C.V.  (“Minera  Mexico”),  which  we  acquired  in  2005.  Minera  Mexico  engages 

principally in the mining and processing of copper, molybdenum, zinc, silver, gold 

and lead. Minera Mexico operates through subsidiaries that are grouped into three 

separate units. Mexicana de Cobre S.A. de C.V. (together with its subsidiaries, the 

“Mexcobre  unit”)  operates  La  Caridad,  an  open-pit  copper  mine,  a  copper  ore 

concentrator, a SX/EW plant, a smelter, refinery and a rod plant.

Operadora  de  Minas  e  Instalaciones  Mineras  S.A  de  C.V.  (the  “Buenavista  unit”) 

operates  Buenavista,  formerly  named  Cananea,  an  open-pit  copper  mine,  which 

is  located  at  the  site  of  one  of  the  world’s  largest  copper  ore  deposits,  a  copper 

concentrator  and  two  SX/EW  plants.  The  Buenavista  mine  was  operated  by 

Mexicana de Cananea S.A. de C.V. and by Buenavista del Cobre S.A. de C.V. until 

December 11, 2010. From this date, Industrial Minera Mexico, S.A. de C.V. (together 

with  its  subsidiaries,  the  “IMMSA  unit”)  operated  five  underground  mines  that 

produce zinc, lead, copper, silver and gold, a coal mine and a zinc refinery until July 

2012.  Effective  February  1,  2012,  Minerales  Metalicos  del  Norte  S.A  was  merged 

with  Industrial  Minera  Mexico  S.A.  de  C.V.  (IMMSA).  IMMSA  absorbed  Minerales 

Metalicos del Norte S.A.

We utilize modern/state-of-the-art mining and processing methods, including global 

positioning  systems  and  computerized  mining  operations.  Our  operations  have 

55

a  high  level of vertical integration  that allows us to manage the entire production 

process, from ore mining to the production of refined copper and other products, 

as  well  as  most  related  transport  and  logistics  functions,  using  our  own  facilities, 

employees and equipment.

Actions following company incorporation: 

Capital increase: 

By Public Deed dated May 31, 1995, signed before notary public of Lima, Dr. Carlos 

A. Sotomayor Bernos, the Branch capital increase was formalized. Said increase was 

made through a money contribution by the Company in favor of its Peru Branch and 

by the owners of labor shares, pursuant to Legislative Decree No. 677. The capital 

contribution  made  by  the  Company  aimed  to  increase  the  capital  allotted  to  the 

Branch by Headquarters and registered in Peru. The capital contribution made by 

the owners of Labor Shares (today Investment Shares) was assigned to the Labor 

Shares account of the Branch for issuing new Labor Shares.

Part  of  the  money  contributed  by  the  Company  in  favor  of  its  Branch  and  by  the 

Labor Shares owners was applied as a capital premium to the Resident account as 

Additional Capital.

Exchange of Investment Shares (Labor Shares) for Common Shares:

Dated  September  7,  1995,  “Southern  Peru  Copper  Holding  Company”  was  also 

incorporated  pursuant  to  the  Laws  of  the  State  of  Delaware  to  act  as  the  holding 

company  that  owns  all  of  Southern  Peru  Copper  Corporation  ‘s  shares.  This  was 

executed through an exchange of shares that were formerly denominated “Labor 

Shares”  (now,  Investment  Shares),  which  were  issued  by  the  branch  in  Peru; 

through this operation, owners of labor shares were awarded a specific number of 

Common  Shares,  which  were  issued  by  SPCC  in  the  United  States.  Through  this 

share  exchange,  previous  owners  of  Labor  Shares  acquired  17.31%  of  SPCC’s 

59

Capital  and  this  company  acquired  ownership  of  80.77%  of  Labor  Shares  (now, 

Investment Shares).

SX-EW PADS, TOQUEPALA MINE, TACNA, PERU

On December 31, 1995, Southern Peru Copper Corporation changed its corporate 

name to “Southern Peru Limited”, and “Southern Peru Copper Holding Company” 

changed its corporate name to Southern Peru Copper Corporation.

After the corporate name change, the mining activities of the Company in Peru were 

performed under the name of Southern Peru Limited, Peru Branch (SPL).

On  December  31,  1998,  the  merger  between  Southern  Peru  Copper  Corporation 

and  Southern  Peru  Limited  was  agreed.  The  first  company  absorbed  the  second 

and assumed all its assets and liabilities, including the Branch in Peru. This merger 

did not imply any change to the share percentage in the corporate capital or in the 

Equity Participation Account (Investment Shares), which remained unchanged.

Following  the  merger,  the  corporation’s  mining  activities  in  Peru  were  conducted 

under  the  name  of  Southern  Peru  Copper  Corporation,  Peru  Branch,  or  the 

abbreviated name of “Southern Peru” and/or the acronym SPCC.

Change of Economic Group:

In November 1999, Grupo Mexico S.A.B. de C. V., a firm incorporated pursuant to the 

Laws  of  the  Republic  of  Mexico,  acquired,  in  the  United  States,  100%  of  ASARCO 

Annual Report 2023 
 
 
 
 
 
Incorporated,  the  main  shareholder  of  Southern  Peru  Copper  Corporation  at  that 

time. In this way, SPCC became a subsidiary of Grupo Mexico, which holds its shares 

through Americas Mining Corporation (AMC).

Acquisition of Minera Mexico (“MM”), and other corporate changes:

SCC  shareholders,  in  a  shareholder  extraordinary  meeting  dated  March  28, 

2005,  approved  the  issuance  of  Common  Shares  and  required  actions  related  to 

the  acquisition  of  MM,  a  firm  incorporated  pursuant  to  the  Laws  of  the  Republic 

of  Mexico.  This  transaction  was  approved  by  more  than  90%  of  the  stocks  and 

circulating capital of SCC. To acquire Minera Mexico, SCC issued 67,207,640 shares 

in exchange for MM shares. Once the shares related to the acquisition were issued, 

AMC increased its share in SCC from 54.2% to approximately 75.1%.

AMC Increased its Participation in SCC:

In  2008  and  2009,  Grupo  Mexico,  through  its  wholly  owned  subsidiary  Americas 

Mining Corporation, purchased 11.8 million and 4.9 million shares of the Company’s 

common Stock, respectively.

61

SCC $500 Million 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. The SCC share repurchase program has registered no activity since the 

third quarter of 2016. The NYSE closing price of SCC common shares at December 

31, 2022 was $60.39 and the maximum number of shares that the Company could 

purchase at that price was 1.4 million shares.

As  a  result  of  the  repurchase  of  shares  of  SCC’s  common  stock,  Grupo  Mexico’s 

direct and indirect ownership was 88.9% as of December 31, 2022.

Change in the Certificate of Incorporation:

On  March  28,  2005,  following  Board  of  Directors  recommendations,  SCC 

shareholders  approved,  during  an  extraordinary  meeting,  the  amendments  to  the 

Articles  of  Incorporation  Deed  that  changed  the  composition  and  obligations  of 

some Board committees.

Special Nominating Committee and Special Independent Directors:

The changes to the Certificate of Incorporation require the Board to include a certain 

number  of  special  independent  directors.  The  Special  Nominating  Committee 

functions  as  a  special  committee  to  nominate  special  independent  directors  to 

the  Board.  Pursuant  to  our  Amended  and  Restated  Certificate  of  Incorporation, 

as  amended,  a  special  independent  director  is  any  director  who  (i)  satisfies  the 

independence requirements of the New York Stock Exchange or NYSE (or any other 

exchange or association on which the Common Stock is listed) and (ii) is nominated 

by the Special Nominating Committee. The Special Nominating Committee has the 

right to nominate a given number of special independent directors; this number is 

found by multiplying the total number of directors in the Board by the percentage 

of  Common  Shares  all  the  shareholders  (that  are  not  Grupo  Mexico  and  its 

affiliates) have, rounding up to the following integer number.   Notwithstanding the 

aforementioned, the total number of individuals appointed as special independent 

directors (not belonging to Grupo Mexico) cannot be less than two or more than six.

Annual Report 2023 
 
 
 
The  Special  Nominating  Committee  consists  of  three  directors.  Two  of  these 

directors (2) are Luis Miguel Palomino and Carlos Ruiz Sacristan (each is an “Initial 

Member” and, together with their successors, “Special Designees”) and the third is 

currently Xavier Garcia de Quevedo (who is appointed by the Board of Directors or 

the “Board Designee”. The Board Designee will be selected annually by the Board 

of  Directors.  The  Special  Designees  will  be  selected  annually  by  the  members  of 

the Board who are special independent directors or Initial Members. Only Special 

Independent Directors can fill vacancies on the Special Nominating Committee. Any 

member of the Special Nominating Committee may be removed at any time by the 

Board of Directors for cause. The unanimous vote of all members of the nominating 

committee will be necessary for the adoption of any resolution or the taking of any 

action.

Notwithstanding the foregoing, the power of the Special Nominating Committee to 

nominate special independent directors is subject to the rights of the stockholders 

to make nominations in accordance with our by-laws.

The  provisions  of  the  Amended  and  Restated  Certificate  of  Incorporation,  as 

amended, relating to Special Independent Directors may only be amended by the 

affirmative vote of a majority of the holders of shares of Common Stock (calculated 

without giving effect to any super majority voting rights) other than Grupo Mexico 

and its affiliates.

Transactions with affiliates:

The Company entered into certain transactions in the ordinary course of business 

with parties that are controlling shareholders or their affiliates. These transactions 

63

include  the  lease  of  office  space,  air  and  railroad  transportation,  construction 

services,  energy  supply  and  other  products  and  services  related  to  mining  and 

refining.  The  Company  lends  and  borrows  funds  among  affiliates  for  acquisitions 

and  other  corporate  purposes.  These  financial  transactions  bear  interest  and  are 

subject  to  review  and  approval  by  senior  management,  as  all  are  related  party 

transactions.  It  is  the  Company’s  policy  that  the  Audit  Committee  of  the  Board  of 

Directors  shall  review  all  related  party  transactions.  Article  nine  of  the  amended 

and reformulated Deed of Constitution of the Company is prohibited from entering 

or continuing a material related party transaction that has not been reviewed and 

approved  or  ratified  by  a  Board  Committee  consisting  of  at  least  three  members, 

each of whom is independent, and defines a material transaction between affiliates 

as a transaction or series of related transactions between Grupo Mexico or one of 

its affiliates (other than the Company or its subsidiaries), on the one hand, and the 

Company or one of its subsidiaries, as the other party, in which there is economic 

consideration  for  an  aggregate  total  of  more  than  $10.0  million.  It  is  the  policy  of 

the  Company  (i)  that  no  material  transaction  between  affiliates  shall  be  entered 

into  or  continued  without  the  review  and  approval  of  the  Audit  Committee  or 

its  Subcommittee  on  Related  Party  Transactions  constituted  by  independent 

directors,  (ii)  that  any  transaction  process  between  potential  related  parties  with 

aggregate total consideration between $8.0 million and $10.0 million is authorized 

by  the  Company’s  General  Counsel  and  Chief  Financial  Officer,  and  (iii)  that  all 

related  party  transactions,  including  any  material  transactions  between  affiliates, 

are reported to the Audit Committee of the Board of Directors or its Related Party 

Transactions Subcommittee.  

Change of corporate name and other corporate changes:

On September 20, 2005, by written consent instead of an extraordinary shareholder 

meeting,  the  majority  shareholder  approved  renaming  Southern  Peru  Copper 

Corporation  to  Southern  Copper  Corporation  or  SCC.  The  change  was  adopted 

because  the  new  corporate  name  more  accurately  reflects  the  Company’s 

operational reach outside the Republic of Peru after its acquisition of Minera Mexico, 

and the latter’s presence in the Republic of Chile through the acquisition of some 

mining  exploration  concessions,  and  its  exploration  activities  in  the  Republics  of 

Argentina and Ecuador.

Annual Report 2023 
 
 
 
Additionally, on the same date, the majority shareholder approved an amendment to 

our Articles of Incorporation to remove others’ provisions in our Articles of Incorporation 

related to our Class A Common Shares that were formerly in circulation, which were 

converted to Common Shares on May 19, 2005, and to change the number of Corporate 

directors  from  fifteen  to  a  number  that  will  be  regularly  established  by  a  consensus 

reached by the majority of Board members and stipulating that the number of directors 

will not be less than six or more than fifteen.

The amendment of our Articles of Incorporation was submitted to the Secretary of State 

of the State of Delaware, and came into effect on October 11, 2005.

Peru Branch Name:

Generally,  any  change  in  the  corporate  name  of  headquarters  should  comprise  the 

corresponding name of the ancillary organizations linked to it, as is the case of the Peru 

Branch through which the Corporation develops its mining activities in Peru.

After  consulting  with  Peruvian  lawyers,  the  Board  of  Directors,  in  acknowledgement 

of the importance of the net worth and assets of the Branch, decided it was necessary 

to:  continue  acknowledging  the  position  of  the  Peruvian  Branch  with  its  local  and 

international copper clients; preserve its proceeds, position its good name in the copper 

market;  prevent  any  possible  client  loss;  and  guarantee  the  Branch’s  revenue  flow 

from sales, its financial and economic revenues and solvency, agreed to maintain the 

original corporate name of the Peru Branch, that is, Southern Peru Copper Corporation, 

Peru Branch, or the abbreviated name “Southern Peru” and/or the acronym SPCC.

Changes to the Articles of Incorporation and By-laws

On  January  26,  2006,  the  Board  approved  an  amendment  to  Southern  Copper 

65

Corporation’s Articles of Incorporation and by-laws: (i) to remove the provisions related 

to Class A Common Shares among other changes.(ii) add a new provision for advance 

notice to shareholders seeking to nominate directors or to propose other business at 

annual or special meetings of the Common Stockholders (as applicable) (iii) substitute 

Grupo Mexico for ASARCO Incorporated in the “Change in Control” definition in the 

Corporation’s  by-laws  (iv)  and  eliminate  the  80%  supermajority  vote  requirement 

for  certain  corporate  actions.  The  modification  of  the  Modified  Certificate  of 

Incorporation increased the capital stock from 167,207,640 shares to 320,000,000 

shares.  These  modifications  were  submitted  for  approval  of  the  shareholders  at 

the shareholders annual meeting held on April 27, 2006 which was adjourned and 

reconvened for May 4, 2006, and later on adjourned and reconvened for May 11, 

2006.

At  the  annual  meeting,  on  April  27,  2006,  the  proposal  to  amend  the  by-laws  to 

eliminate  certain  extraneous  provisions  relating  to  the  retired  series  of  Class  A 

Common Stock had an affirmative vote of 79.85% of the required votes. Given that 

the required vote for the approval of this proposal was 80% and because some votes

Relationship between the Issuer and the Government: 

On  November  20,  1996,  SCC  and  the  Peruvian  Government  (Ministry  of  Energy  and 

Mines) signed a contract that remained effective until the year 2010 and guaranteed 

the  tax  stability  and  the  availability  of  exchange  to  foreign  currency  of  the  Branch’s 

earnings  related  to  the  operation  of  the  SX/EW  plant  at  Toquepala  and  the  Solvent 

Extraction  (SX)  operation  in  Cuajone.  Additionally,  on  April  18,  1995,  SCC  and  the 

Peruvian Government (CONITE) signed a contract that remained in effect for ten years 

and guaranteed the availability of foreign currencies, free remittance of dividends to 

the exterior, among other guarantees related to the acid plant of the Ilo Smelter.

SCC  obtains  refunds  for  tax  credits  in  Peru  for  the  general  sales  tax  (IGV)  paid  in 

connection with the acquisition of capital goods and other goods and services used 

in  its  operations,  counting  these  credits  as  a  paid  expense  in  advance.  By  virtue  of 

these refunds, SCC is entitled to credit the amount of the IGV against its Peruvian tax 

obligations or to receive a refund.

Special Mining Tax: 

In September 2011, the Peruvian government enacted a new tax for the mining sector. 

This tax is based on operating profit and its rate varies from 2% to 8.4%. The Company 

provisioned  $71.7  million,  $56.4  million  and  $114.0  million  in  2023,  2022  and  2021, 

respectively, with respect to this tax. These amounts are included as “income taxes” in 

the consolidated statement of income.

Mining Royalty:

The royalty charge is based on operating income margins with graduated rates ranging 

from 1% to 12% of operating profits, with a minimum royalty charge assessed at 1% of 

net sales. The minimum royalty charge is recorded as cost of sales and those amounts 

assessed at higher rates are included in the income tax provision. The Company has 

accrued $84.7 million, $71.4 million and $140.8 million of royalty charges in 2023, 2022 

and 2021, respectively, of which $44.5, $35.8 million and $97.8 million were included 

in income taxes in 2022, 2021 and 2020, respectively.

Social Investment for Taxes: 

SCC has signed agreements with Ministry of Education, regional and local governments 

of  Tacna,  Moquegua,  and  Arequipa,  and  a  public  university  “Universidad  Nacional 

San  Agustin  de  Arequipa”  under  the  law  of  Social  Investments  for  Taxes  (Obras  por 

Impuestos).  Once the investments are completed, the municipalities benefiting from 

these investments must submit a certificate of public, local or regional investment.  SCC 

has the right to use these investment amounts as an advance payment on its income 

tax liability for up to 50% of the income tax levied for the prior year.

The  SX  EW  facility  has  an  annual  design  capacity  of  21,900  tonnes  of  copper 

cathodes.  These  cut-off  grades  need  to  be  reassessed  as  the  mineral  reserves 

stated were estimated utilizing an economic cut-off value.

La Caridad Metallurgic Complex

“La  Caridad  Smelter”  started  operations  in  July,  1986.  The  current  installed 

capacity of the smelter is 1,000,000 tonnes per year, which is sufficient to treat all 

the  concentrates  of  La  Caridad  and  almost  40.5%  of  the  total  production  of  the 

OMIMSA I and OMIMSA II concentrators from Buenavista. In 2010, the smelter also 

began processing concentrates from the IMMSA mines after we closed the San Luis 

Potosi smelter.

“La Caridad Refinery” started operations in July, 1997 with a production capacity 

of 493 tonnes of copper cathode per day, which was expanded to 822 tonnes in 

January, 1998. The installed capacity of the refinery is 300,000 tonnes per year.

“La  Caridad  Precious  Metals  Plant”  started  operations  in  May,  1999.  The 

operations at the precious metal refinery begin with the reception of anodic slimes, 

which  are  dried  in  a  steam  dryer.  After  this,  the  dried  slime  is  smelted  and  a  gold 

and  silver  alloy  is  obtained,  which  is  known  as  Dore.  The  precious  metal  refinery 

plant has a hydrometallurgical stage and a pyrometallurgical stage, in addition to 

a steam dryer, Dore casting system, Kaldo furnace, 20 electrolytic cells in the silver 

refinery,  one  induction  furnace  for  fine  silver,  one  silver  ingot  casting  system  and 

two reactors for obtaining fine gold. The process ends with the refining of the gold 

and silver alloy.  We also recover commercial selenium from the gas produced by 

the Kaldo furnace process.

69

“La  Caridad  Wire  Rod  Plant”,  a  rod  plant  at  the  La  Caridad  complex,  began 

operations in 1998 and reached its full annual operating capacity of 150,000 tonnes 

in 1999. The plant is producing eight-millimeter copper rods with a purity of 99.99%.

Effluent  and  Dust  Treatment  Plant,  in  2012,  we  began  the  operation  of  a  dust 

and effluent plant with a treatment capacity of 5,000 tons of foundry dust per year, 

which will produce 1,500 tons of copper byproducts and 2,500 tons of lead sulfates 

per  year.  This  plant  is  designed  to  reduce  dust  emissions  from  the  La  Caridad 

metallurgical complex.

Buenavista Mine

“Buenavista  Concentrator”,  the  original  concentrator  currently  has  a  nominal 

milling  capacity  of  82,000  tonnes  per  day.  The  second  concentrator  began 

operations in 2016 with a nominal milling capacity of 115,000 tonnes per day. 

“Buenavista  SX/EW  I  Plant”,  facilities  have  a  cathode  production  capacity  of 

174,470 tonnes per year.

“Buenavista  SX/EW  II  Plant”,  started  operating  in  1989  with  a  capacity  of  66 

tonnes per day, which was expanded to 120 tonnes per day in 2001.

“Buenavista SX/EW III Plant” started operating in June 2014; we completed the 

construction  of  a  new  SX-EW  plant  that  has  significantly  increased  production  of 

leachable material by approximately 120,000 tonnes per year. The SX-EW facilities 

have a cathode production capacity of 174,470 tonnes per year.

Mexican operations
69.8%  of  our  10,802  Mexican  employees  were  unionized  as  of  December  31, 

2023 and are represented by ten different unions. Under mexican law, the terms of 

employment for unionized workers are set forth in collective bargaining agreements. 

81

Mexican  companies  negotiate  the  salary  provisions  of  collective  bargaining 

agreements with the labor unions on an annual basis and negotiate other benefits 

every two years. We conduct negotiations separately at each mining complex and 

each processing plant. 

In recent years, the Mexican operations have experienced a positive 

improvement  in  their  labor  environment,  as  workers  opted  to 

change their affiliation from the “Sindicato Nacional de Trabajadores 

Mineros,  Metalurgicos  y  Similares  de  la  Republica  Mexicana”  (the 

“National Mining Union”) to other less politicized unions.

Peruvian operations
60.9% of the Company’s 4,979 Peruvian employees were unionized 

at December 31, 2022. Currently, there are six separate unions, none 

of  which  represents  the  majority  of  workers,  as  defined  by  current 

peruvian labor legislation.

Corporate Notes 

Between July 2005 and October 2015, the Company issued senior unsecured notes eight times totaling 

$6.2 billion. Interest on the notes is paid semi-annually in arrears. The notes rank pari passu with each other 

and rank pari passu in right of payment with all of the Company’s other existing and future unsecured and 

unsubordinated indebtedness.

The indentures relating to the notes contain certain restrictive covenants, including limitations on liens, 

limitations  on  sale  and  leaseback  transactions,  rights  of  the  holders  of  the  notes  upon  the  occurrence 

of  a  change  of  control  triggering  event,  limitations  on  subsidiary  indebtedness  and  limitations  on 

consolidations, mergers, sales or conveyances. Certain of these covenants cease to be applicable before 

the notes mature if the Company obtains an investment grade rating. The Company obtained investment 

grade rating in 2005.

In addition, the Company´s Mexican operations hold $51.2 million in bonds referred above as “Yankee 

bonds”,  contain  a  covenant  requiring  Minera  Mexico  to  maintain  a  ratio  of  EBITDA  to  interest  expense 

of not less than 2.5 to 1.0 as such terms are defined in the debt instrument. At December 31, 2022, the 

Company was in compliance with this covenant.

On September 26, 2019, Minera Mexico S.A. de C.V., a subsidiary of SCC, issued $1 billion Senior Notes at 

a fixed rate with a discount of $12.7 million, which will be amortized over the corresponding debt period. 

Additionally,  issuance  costs  of  $9.8  million  corresponding  to  these  notes  were  paid  and  deferred.  The 

unamortized balance of the discount and the costs of this bond are presented net of the book value of 

the debt issued and are amortized as financial expenses over the life of the loan. This debt was issued 

in  a  single  tranche,  maturing  in  2050  at  an  annual  interest  rate  of  4.5%.  Interest  on  the  notes  is  paid 

semiannually after maturity.

The Company intends to use the net proceeds from this offering (i) to finance Minera Mexico’s expansion 

program, including the Buenavista Zinc, Pilares and El Pilar projects, (ii) for other capital expenditures and 

(iii) for general corporate purposes.

85

The  notes  constitute  general  unsecured  obligations  of  Minera  Mexico.  The  notes  were  issued  in  an 

unregistered offering pursuant to Rule 144A and Regulation S under the Securities Act of 1933.

Please see Note 11 “Financing” for a discussion about the covenants’ requirements with regard to our 

long-term debt, on our 2023 Form 10-K.
