LETTER TO SHAREHOLDERS

In 2008, as a result of world’s unsettled economy metal prices were 
negatively impacted. Net sales declined 20.3%, from $6,085.7 
million in 2007 to $4,850.8 million in 2008. But, the most dramatic 
decrease occurred in fourth quarter 2008 compared with the fourth 
quarter of 2007. The LME and COMEX copper prices averaged $1.77 
and $1.75 per pound, respectively, in the fourth quarter of 2008, 
compared with $3.26 and $3.25, respectively, in the fourth quarter 
of 2007. 

The pricing system in the mining industry, in many cases, allows for 
prices to be settled after the product is already delivered, genera-
lly one or two months after the shipment, this gives customers a 
better ability to match more closely their sales prices to the cost 
of the material.   So, in a period with a sudden change in prices, 
adjustments have to be made to sales. In the fourth quarter of 
2008 copper and molybdenum prices dropped sharply, this requi-
red a large downward adjustment  in sales value of $419 million and 
a decrease in net profit of approximately $261 million. We do not 
expect these negative adjustments to be repeated in the near term. 

Partially as a result of these price adjustments, Company earnings 
in the fourth quarter of 2008, compared to the fourth quarter of 
2007, decreased to a loss of $124.7 million from net earnings of 
$310.9 million. For the year 2008, Company earnings were $1,406.6 
million a decrease of 36.5% from 2007. 

The decrease in net sales, in fourth quarter and in year 2008 was 
partially offset with gains of $74.2 and $137.0 million, respectively, 
on copper hedge transactions. 

In fourth quarter of 2008, fuel, power, and repair material cost 
decreased by 14%, 23%, and 21%, respectively, when compared with 
the third quarter in 2008.  In light of these decreases, our opera-
ting cash cost, before byproduct credits, in the fourth quarter 2008 
were 26.4% lower than the third quarter 2008.  The operating cash 
cost per pound for the year 2008, including the benefit of bypro-
duct credits was 34.1 cents per pound.

After what has happened in 2008 and what could happen in 2009 
and beyond, we believe Southern Copper Corporation has one of 
the best copper ore reserves in the industry, as well as very signifi-
cant reserves of molybdenum, silver and zinc.  We expect that these 
reserve positions will allow our Company to operate profitably into 

04 - 05 05 

SOUTHERN COPPER 2008

the foreseeable future.

Our Company’s low operating costs, strong cash position of $716.7 
million and low debt level of $1,290.0 million, with no significant 
amortizations until 2015, will permit us to continue with a profitable 
operation. At the same time, we have reduced significantly most of 
our capital investments in new as well as in expansion projects; as 
we believe this prudence and business discipline is needed during 
the current low commodity cycle. 

Copper production in 2008 was 488,929 tons, compared with 
592,182 tons in 2007, a decrease of 17.4%, and principally due to 
strike closed operations in three of our Mexican mines: Cananea, 
Taxco and San Martin, and lower ore grades at the Toquepala and 
La Caridad mines. Smelted and refined copper production in the 
fourth quarter 2008 were 29.3% and 26.3% higher than in fourth 
quarter 2007, mainly due to the full capacity production at our 
modernized Ilo smelter plant, 7.1% higher concentrates production 
at La Caridad mine and the processing of third party copper at the 
Caridad smelter. 

Molybdenum production was 16,390 tons in year 2008 compared 
with 16,207 tons in 2007. This increase of 1.1% was due to higher 
ore grade at La Caridad mine and higher recovery at Cuajone mine 
partially offset by lower ore at Toquepala mine. 

Refined zinc production for the year 2008 was 95,420 tons, 5.1% 
higher than in 2007 due to the recovery of full capacity at the San 
Luis Potosi refinery. Refined silver in year 2008 increased by 8.4% 
compared with year 2007.  Sulfuric acid production increased 5.5% 
in year 2008 compared to year 2007. 

In 2008, the Company exceeded its production objectives at the 
open pit mines of Toquepala, Cuajone and La Caridad, as well as 
in the IMMSA underground units of Charcas, Santa Eulalia, Santa 
Barbara, the coking facility at Nueva Rosita and the La Caridad 
precious metals plant.

As part of our share repurchase program approved by the Board 
in 2008, Southern Copper has purchased 29.6 million shares of its 
common stock at an average price of $13.52 per share. With these 
repurchases the outstanding shareholders have increased their 
stake in the Company by 3.5%.

As a result of world’s unsettled economy and the reduction in metal 
prices, SCC has decided to reduce dramatically or put on hold capital 
projects. In 2008 we expended $343.8 million on projects, $172.8 
million on maintenance and replacement capital expenditures and 
$37.0 million on exploration, a combined total of $553.6 million. 
For 2009 we have reduced our capital and exploration budget from 
$1,070 million to approximately $415.3 million. Of this amount, $311.2 
million would be for projects, $81.4 million for maintenance and 
replacement capital expenditures and $22.7 million for exploration.

The Company will continue with the environmental projects at its 
mining and metallurgical facilities. At La Caridad metallurgical 
complex the gas handling, and dust and effluent treatment projects 
are being completed. These projects are at 93% and 70% of comple-
tion, respectively, and have a combined budget of $9.0 million for 
2009.

The Agua Prieta lime plant modernization project, in the Mexican 
state of Sonora, is moving forward to completion. When finished, this 
project is expected to reduce the annual lime cost of our Mexican 
operations by approximately $9.0 million. Due to its capital budget 
of $14.0 million this project yields an attractive return.

In Peru, for the Cuajone expansion project we have signed a feasibi-
lity study contract and will only continue at this point with the engi-
neering and the environmental impact assessment.

Regarding our copper deposit projects at Los Chancas in Peru, El 
Arco, Pilares and the underground polymetallic mine in Angangueo 
in Mexico, we will continue to evaluate these projects, but will defer 
making a final decision until better market conditions make it more 
prudent to move forward on these projects.

SOUTHERN COPPER 2008

We believe that the measures implemented will allow us to conso-
lidate our position as one of the largest and most efficient metal 
producers in the world, which we believe will give an economic 
return to our shareholders, a contribution to the countries and loca-
lities where we operate, as well as a benefit for our workers, despite 
the world’s economic problems. 

On behalf of Southern Copper Corporation’s Board, we express our 
thanks to all our personnel for their effort, work and dedication, 
to our clients for their continued trust and loyalty, and to you, our 
shareholders, for your permanent support.

EXPANSION AND MODERNIZATION PROGRAM 

Mexican OperatiOns

The Company will continue with the environmental projects at its 
mining and metallurgical facilities.  At La Caridad metallurgical 
complex the gas handling and dust and effluent treatment projects are 
being completed. These projects are at 93% and 70% of completion, 
respectively, and have a combined budget of $9.0 million for 2009.

The Agua Prieta lime plant modernization project, in the Mexican 
state of Sonora, is moving forward to completion. When finished, this 
project is expected to reduce the annual lime cost of our Mexican 
operations by approximately $9.0 million.  The capital budget for 
this project is $14.0 million.

peruvian OperatiOns

Concerning the expansion and modernization program that has 
been taking place in recent years, we note the following:

The tailings disposal project for Toquepala and Cuajone is in progress. 
This project will increase the height of the existing Quebrada Honda 
Dam to impound future tailings from the Toquepala and Cuajone 
mills. The installation of the main equipment and construction of 
access roads for the main and lateral dams have been completed. 
The first stage of this project will be under development until 2012  
and will be completed in March 2009.

The replacement and installation work for the new primary crusher 
in the Toquepala concentrator was completed; in order to avoid loss 
of production, the primary crushing for the leaching dumps was 
used while replacing the original concentrator crusher.

In 2008, the modernized Ilo smelter plant registered a 95% average 
of sulfur capture. 

 
17 17 

Construction of the marine trestle at Ilo to offload sulfuric acid 
was restarted upon the receipt of authorization from the Peruvian 
Harbor National Authority.  The project has reached 66% progress.

The Los Chancas project, located in the department of Apurimac in 
southern Peru, is a copper and molybdenum porphyry deposit. 

As a result of the pre-feasibility studies and after the preliminary 
design of the pit, estimates show 355 million tons of mineralized 
material with a copper content of 0.62%, 0.05% of molybdenum 
and 0.039 grams of gold per ton. In the last quarter of 2008, 
additional studies were started as well as a diamond drilling program 
for additional 35,000 meters, in order to define the extent of the 
deposit.  Also a bidding process is under way for a feasibility study 
to be developed in 2009. While we will continue to evaluate Los 
Chancas we will defer making a final decision on development until 
economic conditions improve.

Tia Maria: The Tia Maria project, which includes the Tia Maria and 
the La Tapada deposits, is located in the department of Arequipa 
on the southern coast of Peru and is part of a copper porphyritic 
system. The feasibility studies in 2008 for Tia Maria show 193 million 
tons of mineralized material with 0.302% copper content. 

For La Tapada, the estimated mineralized resources show 445 
million tons of mineralized material, with 0.434% copper content. 

In 2008, the Company completed the basic engineering and started 
the detailed engineering studies for the project. The environmental 
impact assessment is expected to be completed in the second 
semester of 2009.

As of December 31, 2008, we have spent $118.0 million for the Tia 
Maria project. We are currently evaluating whether to put on hold 
or to slow down the spending in light of current market conditions 
and capital equipment cost. 

We estimate spending $112.3 million on this project during 2009, 
which includes funds necessary to complete environmental and 
engineering studies, as well as spending previously committed. 
When completed the new operating unit is expected to produce 
120,000 tons of copper cathodes per year.

Toquepala concentrator expansion: As of December 31, 2008, we 
have spent $37.7 million for the Toquepala expansion. This project 
is designed to increase annual Toquepala copper production by 
approximately 100,000 tons per year. We completed the feasibility 
study. The basic engineering is almost completed and detailed 
engineering will be started. The environmental impact assessment 
is also underway and is expected to be completed in the fourth 
quarter of 2009. We expect to spend $65.5 million in 2009 to 
complete studies and for previously committed purchase orders. 
After that, we will put on hold making any new additional capital 
spending commitments for this project.

Feasibility Study for Cuajone Expansion to 105,000 metric tons per 
day was completed. However, any further spending is being deferred 
pending improvement in economic conditions.

EXPLORATION

Mexican OperatiOns

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

el arco. The El Arco site is located in the state of Baja California in 
Mexico. Preliminary investigations of the El Arco site indicate a deposit 
of 846 million tons of mineralized material with average copper 
grades of 0.51% and 0.14 grams of gold per ton, and 170 million tons of 
leach mineralized materials with average copper grades of 0.56%. In 
2008, we have continued the process of identifying water sources for 
a leaching operation. Production wells will be tested to determine the 
water potential of this area. Also, five diamond drill holes have been 
drilled to a depth of 600 meters. The drilling indicates mineralized 
material, with 0.50%-0.70% copper mineralization extending 270 
meters below the previously known mineralization.

angangueo. The Angangueo site is located in the state of Michoacan 
in Mexico. A deposit of 13 million tons of mineralized material has been 
identified with diamond drilling. Testing indicates that the deposit 
contains mineralized material containing 0.16 grams of gold and 
262 grams of silver per ton, and is comprised of 0.79% lead, 0.97% 
copper and 3.5% zinc. During 2005, we received the approval for our 
environmental impact study and we are in the process of obtaining 
land use approval. During 2008, we have continued negotiating with 
the state of Michoacan to purchase various properties essential to the 
operation. In addition, a feasibility study was commissioned; the results 
are expected to be available by the end of first quarter 2009.

23 23 

Buenavista. The Buenavista project site is located in the state of 
Sonora in Mexico, adjacent to the Cananea ore body. Drilling and 
metallurgical studies have shown that the site contains 36 million 
tons of mineralized material containing 29 grams of silver, 0.69% 
of copper and 3.3% of zinc per ton. A new “scoping level” study 
indicates that Buenavista may be an economical deposit. During 
2007, 2,100 meters were drilled to upgrade the mineralized material 
and to acquire material for metallurgical testing. Results confirm the 
previous geologic interpretation of the mineralized areas. Due to the 
Cananea strike no work was performed in 2008.

carbon coahuila. In Coahuila, an intensive exploration program of 
diamond drilling has identified two additional areas, Esperanza with 
a potential for more than 30 million tons of “in place” mineralized 
coal and Guayacan with a potential for 15 million tons of “in place” 
mineralized coal, that could be used for a future coal-fired power plant. 
During 2007 along with 5,767 meters of drilling, 23 million tons of 
mineralized coal resources were identified at our Nueva Rosita No. 
16 concession. Due to changed priorities, no work was done on this 
project in 2008.

Los chalchihuites. The Chalchihuites project is located in the state 
of Zacatecas. It is a contact deposit with mixed oxides and sulfides of 
lead, copper, zinc and silver. A drilling program, in the late nineties, 
defined 16 million tons of mineralized material containing 95 grams of 
silver, 0.36% lead, 0.69% copper and 3.08% zinc per ton. Preliminary 
metallurgical testing indicates a leaching precipitating-flotation 
recovery process that can be applied to this ore. Due to other priorities 
only the diamond drilling for metallurgical testing was performed in 
2008.

sierra de Lobos. This project is located southwest of the city of 
Leon, Guanajuato. Our target is a copper and zinc deposit with 
grades between 0.5% and 1.0% copper and between 5% and 7% 
zinc including a small contribution of gold and silver. In 2008, 1,636 
meters were drilled. Results confirm the presence of copper and 
zinc mineralization, but an economic deposit has not yet been 
identified.

pilares. During 2008, we bought Freeport-
McMoran’s 49% interest in Minera Pilares,S.A. 
de C.V. (“Minera Pilares”), giving us 100% 
ownership. Minera Pilares is located in the 
state of Sonora, ten kilometers from the town 
of Nacozari de Garcia. The work to clear and 
prepare the access to the Porvenir tunnel 
started at the end of 2008. Calculations 
using Mine-Sight software indicated 52.9 
million tons of mineralized material, with 
0.92% copper content.

peruvian OperatiOns

In Peru, we have direct control of 194,190 
hectares of mineral rights.

Los chancas. The Los Chancas project, located 
in the department of Apurimac in southern 
Peru, is a copper and molybdenum porphyry 
deposit. As a result of the pre-feasibility 
studies and after the preliminary design of 
the pit, estimates show 355 million tons of 

mineralized material with a copper content 
of 0.62%, 0.05% of molybdenum and 0.039 
grams of gold per ton. In the last quarter of 
2008 additional studies were started as well 
as a diamond drilling program for additional 
35,000 meters, in order to define the extent 
of the deposit. Also a bidding process is under 
way for a feasibility study to be developed in 
2009.

tantahuatay. The Tantahuatay project is 
located  in  the  department  of  Cajamarca 
in  northern  Peru.  The  exploration  work 
conducted in 2008 was intended to evaluate 
the upper part of the deposit mainly for gold 
recovery. Work to date indicates 27.1 million 
tons of mineralized material, with an average 
silver content of 13.0 grams per ton and 0.89 
grams of gold per ton. In 2008 we continued 
with the feasibility study and with our efforts 
to  resolve  the  social  and  environmental 
concerns of communities near the project. 
We have a 44.25% share in this project.

COMMUNITY OUTREACH 

Mexican OperatiOns

Due to the extended strike at Cananea and its severe consequences 
for both the local residents and the Company, it was decided to 
undertake a social initiative.  The Company contracted a consulting 
group (Grupo Encuentro) who, using novel and original ideas for 
community participation, approached local groups and helped to 
improve relations between the Company and the local population.

Grupo encuentro
The project was carried out over a period of 100 days and it consisted 
of participatory diagnosis and the identification of local leaders 
who contributed to the success of the projects, as well as knowing 
community needs and helping  to develop social projects. 

The activities included 18 workshops with various participants, 2 youth 
camps, 8 in-depth interviews, 5 focus groups, 122 random interviews, 
7 tours and the “Tree of Commitments” in which the children put into 
practice skills and human values necessary to face the social and 
economic reality of the community and made personal commitments 
to the city.

Grupo Encuentro involved mothers and fathers, children, seniors, 
workers, religious, teachers, traders and other actors in society in 
the experience of the workshops and the activities at Cananea, all of 
them benefited with the lessons learned from these experiences and 
emotions. 

During 2008, operations started in the community centers of the 
mining units of Santa Eulalia, Santa Barbara and Planta de Nueva 
Rosita, Coahuila. Activities offered in each of these centers benefit 
more than 600 people, including women, men, children and older 
adults.  At present, workshops and talks are being presented on dance, 
computers, carpentry, tailoring, baking, manual works and bijouterie, 
all of which has generated a large degree of community  participation.

29 29 

IMMSA, in collaboration with the Secretariat 
of the State of Coahuila, provided training 
for  22  people  at  the  following  locations; 
Rosita, Palau and Sabinas Coahuila, to work 
in area production projects. As a result of the 
efforts of the Secretariat and the National 
Fund for Support to Solidarity Enterprises 
(Fondo Nacional de Apoyo a las Empresas de 
Solidaridad -FONAES) three of the 22 projects 
are underway: a carpentry shop, a grocery, a 
cibercoffee and pancake store. All of them 
have been successful. It is hoped that these 
type of projects can benefit more people in 
the community and could help generating 
self-employment. 

In order to promote safety and health at 
work among the personnel, their families 
and the community at large, we carried out 
a “Safety and Health Week 2008” at Planta 
de Cobre, Units Santa Barbara, Charcas and 
Taller Central.

In San Luis Potosi health fairs were conducted, 
with 6,300 participants.  These fairs focused 
on the detection, promotion and appropriate 
channeling of chronic degenerative diseases. 
Ten lectures were conducted on preventive 
medicine with the participation of over 300 
people from the neighboring community. 
Issues such as oral hygiene, breast cancer, 
diabetes and hypertension, cervical cancer, 
nutrition and sexuality were presented and 
discussed at these lectures.

peruvian OperatiOns

Southern  Copper  promotes  sustainable 
development projects in the upper Andean 
communities  of  Tacna,  Moquegua  and 
Arequipa, which are located close to our 
principal operating facilities.   This support 
is from voluntary contributions made by our 
Company to the “Asociacion Civil Ayuda del 
Cobre” (Civil Aid Copper Association) under 
an  agreement  signed  with  the  Peruvian 
government.  

The  projects  within  this  program  work 
i n   p a r tn e r sh i p   with   l o c a l   p u b li c   a n d 
nongovernmental organizations to achieve the 
benefit from legislation and the participation of 
the neighboring communities; thereby taking 
into account legislation and the historical and 
cultural characteristics of each locality.

During 2008, Southern Copper has developed 
the following programs and projects:

•  Water  resources.-  We  believe  the  most 
significant achievement is the completion of 
the construction and improvement of Marisol 
Hydraulic Splitter, a large hydraulic project 
that will benefit the Irrigation Commissions 
of  Cairani,  Candarave,  Huanuara  and 
Quilahuani,  in  the  province  of  Candarave, 
through the equitable distribution of water 
from  the  Callazas  river.    According  to  Dr. 
Julio Kuroiwa Zevallos, the director of the 
National Hydraulic Laboratory, the Marisol 
Hydraulic Splitter has an innovative design 
for the continent. The total investment for 
this project was $311,439.37.

  Minor 

irrigation 

infrastructure  work 
continued in partnership with the irrigation 
committees in Candarave, with an investment 
of $205,741.63, and the construction of the 

30 - 31 31 

SOUTHERN COPPER 2008

Tacalaya-Camilaca’s hydraulic canal ($205,058.00). Both works are 
part of the general irrigation system which relates to the Cularjahuira 
Dike  (which  geotechnical  study,  conducted  by  the  Company,  will 
make possible the construction of a new dam).

  Southern Copper and the National Engineering University signed an 
agreement  for  the  Callazas  Dam’s  feasibility  study.  This  project  is 
considered essential for the agricultural development in the region, 
and  it  is  included  in  the  Development  Plan  of  Tacna,  the  “Plan 
Basadre” sponsored by the regional government of Tacna and the 
Peruvian government. The Company will invest, through the Civil Aid 
Copper  Association,  about    $700,000.00.  The  project  will  include 
three  components:  the  design  of  the  Callazas  Dam,  the  study  for 
the  improvement  of  major  irrigation  infrastructure  and  the  study 
of environmental and social impact. This project will ensure optimal 
and rational use of water resources for agricultural activity during 
the dry season.  

  Also, with an investment of $87,658.90, a geotechnical study for the 
Cularjahuira  Dike  was  completed.    The  dike  is  expected  to  benefit 
the approximately 1,900 inhabitants of the districts of Camilaca and 
Candarave. This study determined the feasibility of building a new 
dam downstream.

•  agronomy.-  The Weeds Control Program was carried out in the 
districts of Cairani, Huanuara and Quilahuani, in Candarave, with 
the  participation  of  local  governments.  The  program  led  to  the 
formation of a control network, formed by the people benefited 
from  each  locality.  By  means  of  this  program,  there  was  a 
decrease  in  the  presence  of  “kikuyu”,  an  invading  plant,  along 
120 kilometers of channels and 30 hectares of alfalfa  cultivation. 
The total investment in the program was $42,033.15.

  A Biological Control Campaign in the Tambo’s Valley, in partnership 
with the National Service of Agrarian Health (Servicio Nacional 
de Sanidad Agraria – SENASA) and the User´s Board, eradicated 
the plague of ‘barreno’ –a type of damaging worm– in rice crops 
in  the  districts  of  Cocachacra  and  Punta  de  Bombon  (Arequipa 
Region). The eradication was done with the release of controlled 

31 31 

wasps  in  a  total  area  of  400  hectares.  According  to  SENASA 
assessments,  in  350  hectares,  the  damage  to  the  rice  crops 
by  attack  of  the  borer  was  reduced  to  less  than  5%,  thus  the 
program will continue.

  Diseases were controlled in the production of oregano, a higher 
quality product in the area. The use of guano (natural fertilizer 
from  sea  birds)  was  promoted  among  the  oregano  producer’s 
associations  of  the  province.    Additionally,  the  producers’ 
association should also benefit from the agreement Strengthening 
Competitive Capacity of the Oregano Producers, signed with the 
non-governmental organization “El Taller” and the municipalities 
of  Cairani,  Huanuara  y  Quilahuani,  in  Candarave.  The  project 
requires a total investment of $135,018.11.

In  Candarave,  the  cultivation  of  thyme,  a  product  used  as 
condiment  and  in  the  pharmaceutical  industry,  was  promoted 
as a alternative product for exportation.  A  field installation of 
canola,  a  seed  that  contains  Omega  3  and  Omega  6  and  which 
produces  vegetable  oil,  was  successfully  completed  in  alliance 
with  the  governmental  program  Exporting  Mountain  (Sierra 
Exportadora).

In  addition,  plantations  of  cereals  such  as  oats  and  corn  were 
promoted, through an agreement signed with the Foundation for 
Agrarian  Development  (Fundacion  para  el  Desarrollo  Agrario  – 
FDA)  and  the  National  Fund  for  Job  Training  and  Employment 
Promotion (FONDOEMPLEO).

•  stockbreeding.-  The Emergency Cattle Care Program was instituted 
to take care of Candarave cattle producers, affected by the drought 
period,  through  the  delivery  of  hay  and  concentrate  at  low  cost. 
This action reduced the shortage of feed for cattle and helped to 
maintain levels of cattle productivity.

   A  contingency  fund  has  been  established  to  assist  producers  in 
dealing with emergencies, which will be used to reduce risks to the 
productive  local  activity.  An  important  part  of  the  production  of 
forage  is  purchased  by  the  program  to  support  local  producers,  to 

 
 
32 - 33 33

whom it generates economic benefits. The investment is $66,455.91 
and the participants in this program are over 800 families.

   The Animal Health Program continues providing veterinary technical 
assistance to producers from 17 communities located in districts of 
Cairani,  Candarave  and  Quilahuani,  in  the  province  of  Candarave. 
Preventive  medicine  and  treatment  for  prevalent  diseases  in  the 
high Andean zone were distributed.

  Also  the  Hampshire  Sheep  Genetic  Improvement  Project  was 
continued. It took place in 5 communities in the Candarave province, 
through  the  use  of  registered  breeders  of  high  genetic  quality  in 
local sheep herds from groups of engaged producers.

  On  the  other  hand,  the  implementation  of  the  Agricultural  Fair  in 
Tacna, like the Farming Fair of Candarave (in terms of organization, 
logistics  and  awards),  event  in  which  the  exhibition  of  the  best 
specimens  of  the  various  breeds  of  cattle,  alpacas,  sheep  and 
Peruvian Paso horses took place. Also, farming fairs in Huaytire and 
Tacalaya were supported.

•  nutrition.- The Nutrition Program called “Southern Forming Healthy 
Communities” (PRONUT) was successfully launched through field 
work in communities in the Tacna Region. The program’s objective 
is to determine baseline statistics to establish or re-initiate goals of 
the program and measure the social impact on beneficiaries. 

  These  activities  included  the  registration  of  the  potential 
beneficiaries and were performed by a team of nutritionists 
and medical laboratory technicians, who, in parallel, tested the 
nutritional status in children under 5 years old, pregnant women 
and nursing mothers in Candarave. 

  The main goal of PRONUT is to significantly reduce the levels of 
chronic malnutrition and anemia in children and women, so that 
they can increase their medium and long term educational and/or 
professional potential.

33 33 

  Concrete actions of the program include the implementation of 
healthy baths, upgraded kitchens, family orchards and ecologic 
bathrooms, small animal farming and continuous training to ensure 
the sustainability of the program.

strengthening of productive capacities
The Alpaca Genetic Improvement Project continues in the community 
of Huaytire, in the province of Candarave. The project uses modern 
techniques for selection, care and breeding species for genetic 
improvement in the medium term, which will benefit the production 
chain and the potential for exportation. For this purpose, different 
activities were performed, including the registration of available 
animals, the acquisition of top quality breeders and the construction 
of infrastructure for breeding. This construction is based on the 
standardized design of the National Institute for Agrarian Innovation. 
It’s built in an area of 180 square meters with capacity to hold up to 
900 alpacas.

In addition, the Alpaca Producers Cluster continues in the community 
of Tacalaya, which, with an initial investment of $79,015.72, aims for 
a mass production of fur hats and alpaca fiber and by-products, with 
the purpose of offering them in the local market  and for export. This 
program includes the development of fur, yarn and textile  projects, 
and process improvements in the manufacture of hats and the 
packaging of oregano products.

The participation of women stands out, taking advantage of their 
craftsmanship. They will bring in to the family an extra income from 
textile workshops, like the one built with the support of the Company 
in community of Santa Cruz (specialized equipment and tools were 
bought for such activities). 

It also highlights the project of strengthening the Torata User 
Board´s capacities, which will allow for optimizing the management 
of water use among farmers of the district in Moquegua, thereby 
maximizing the potential of the sub basins of Torata and Chujulay 
rivers.

•  education.- The rehabilitation and construction of educational 
infrastructure of 56 schools was concluded. It is a process initiated in 
2007 through the construction and/or rehabilitation of classrooms, 
toilets, laboratories, perimeter fences and sport grounds. 

  During 2008, the schools from Cairani, Camilaca, Candarave, 
Huanuara and Huaytire, in Candarave, were provided with furniture, 
blackboards, libraries and computer equipment, which will benefit 
local students. Other districts of the Moquegua Region also received 
benefits.

•  health.- The construction and rehabilitation of 27 health centers 
was  concluded,  in  the  regions  of  Tacna  (Cairani,  Camilaca, 
Candarave, Huanuara and Quilahuani districts) and Moquegua 
(Mariscal Nieto and General Sanchez Cerro provinces, Carumas, 
Cuchumbaya,  Ichuña,  Samegua,  San  Cristobal  and  Torata 
districts). 

  Southern  Copper  promotes  the  sustainable  development  of 
communities located within its area of influence, through the 
Civil Aid Copper Association, which manages and invests in social 
projects for sustainable development funds of the Voluntary 
Contribution program. During 2008, the Company established a 
local fund of $3’664,490.94 and a regional fund of $14’657,963.74, 
to benefit the regions of Tacna and Moquegua.

RESULTS OF O PERATIONS
for the years ended December 31, 2008, 2007 and 2006.

SCC reported 2008 net earnings of $1,406.6 million or diluted earn-
ings  of  $1.60  per  share,  compared  with  net  earnings  of  $2,216.4 
million or diluted earnings of $2.51 per share in 2007 and $2,037.6 
million or diluted earnings of $2.31 per share in 2006.

The decrease in 2008 earnings is mainly due to the lower production 
and the fall in copper prices that began by the end of third quarter 
and continued in the fourth quarter of 2008. 

During 2008, price of copper on the London Metal Exchange (LME) 
and  the  New  York  Commodity  Exchange  (COMEX),  averaged  $3.16 
and $3.13 per pound, respectively, compared to $3.23 and $3.22 per 
pound, respectively, in 2007.

Operating cash cost: The Company presents its operating costs both 
including and excluding the revenues of its byproducts (molybdenum, 
silver, zinc, etc.).  Excluded from its calculation of operating cash cost 
are  depreciation,  amortization  and  depletion,  exploration,  workers 
participation provisions and other items of non-recurring nature.

The  Company’s  operating  cash  cost,  as  previously  defined,  for  the 
three years ended December 31, is as follows:

39 39 

As  seen  on  the  previous  chart,  our  cash  cost  per  pound  for  2008, 
when  calculated  with  by-products  revenue,  are  costs  of  34.1  cents 
per pound compared with a credit of 13.3 cents per pound in 2007. 
The  decrease  in  the  by-products  credit  in  2008  period  was  largely 
due to lower molybdenum prices, especially in the last quarter of the 
year. The effect of lower molybdenum prices reduced the byproducts 
credit by approximately 13.7 cents per pound for 2008.

Our per pound cash cost, excluding by-product revenues, was higher 
by 33.4 cents per pound in 2008 compared to 2007 due to a decrease 
of 17.4% in copper production, principally as a result of the Cananea 
mine  strike,  which  increased  cash  cost  by  18.1  cents  and  the  higher 
power and fuel cost which increased cash cost by 9.9 cents. 

Net  Sales:  Net  sales  in  2008  were  $4,850.8  million,  compared 
with  $6,085.7  million  in  2007  and  $5,460.2  million  in  2006.  Sales 
decreased  by  $1,234.9  million  in  2008,  a  20.3%  decline  from  the 
previous year. The decrease was principally attributable to a decrease 
in sales volume of 16.2% and a decline in metal prices.

Copper  sales  volume  decreased  16.2%  in  2008  due  to  a  17.4% 
decrease  in  production  principally  due  to  the  ongoing  strike  at  the 
Cananea mine and lower ore grades at the Toquepala and La Caridad 
mines. In 2007, we also lost sales volume at Cananea due to a strike 
but to a lesser extent than in 2008. In addition, zinc and silver sales 
volume  decreased  as  result  of  the  strikes  at  some  of  our  other 
Mexican operations.

The decline in metal prices began late in the third quarter of the year 
and  continued  through  the  fourth  quarter.  Copper  was  2.8%  and 
2.2%  lower  in  2008,  depending  on  whether  it  was  COMEX  or  LME 
market, the molybdenum price was 5.0% lower and zinc prices were 
42.2% lower.

Prices: Sales prices for the Company’s metals are established, mainly 
by reference to the prices quoted in the London Metal Exchange (LME) 
and The New York Commodity Exchange (COMEX), or published in the 
Platt’s Metals Week, for dealer oxide mean prices for molybdenum.

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.  Some  of  these  laws  and 
regulations are relevant to legal proceedings 
pertaining to the Company’s San Luis Potosi 
copper facilities.

The  principal  legislation  applicable  to  the 
Company’s Mexican operations is the Federal 
General  Law  of  Ecological  Balance  and 
Environmental  Protection,  which  is  enforced 
by  the  Federal  Bureau  of  Environmental 
Protection (“PROFEPA”). PROFEPA monitors 
compliance  with  environmental  legislation 
and  enforces  Mexican  environmental  laws, 
regulations and official standards. PROFEPA 
initiate  administrative  proceedings 
may 
against companies that violate environmental 
laws,  which  in  the  most  extreme  cases  may 
result in the temporary or permanent closing

regarding 

Mexican  environmental  regulations  have 
become  increasingly  stringent  over  the  last 
decade, and this trend is likely to continue and 
has  been  influenced  by  the  environmental 
treaty entered into by Mexico, United States 
and  Canada  in  connection  with  NAFTA  in 
1999. However, the Company’s management 
does  not  believe  that  continued  compliance 
with  the  federal  environmental 
law  or 
Mexican  state  environmental  laws  will  have 
a  material  adverse  effect  on  the  Company’s 
business,  properties,  results  of  operations, 
financial condition or prospects or will result 
in  material  capital  expenditures.  Although 
the Company believes that all of its facilities 
are  in  material  compliance  with  applicable 
environmental,  mining  and  other  laws  and 
regulations, the Company cannot assure that 
future  laws  and  regulations  would  not  have 
a  material  adverse  effect  on  the  Company’s 
business,  properties,  results  of  operations, 

financial  condition  or  prospects.  Due  to 
the  proximity  of  certain  facilities  of  Minera 
Mexico to urban centers, the authorities may 
implement certain measures that may impact 
or restrain the operation of such facilities.

For  the  Company’s  Mexican  operations, 
environmental  capital  expenditures  were 
$34.1  million,  $25.8  million  and  $5.3  million 
in 2008, 2007 and 2006, respectively.

The  Mexican  Geological  Services  (“MGS”) 
Royalties:  In  August  2002,  MGS  [formerly 
named  Council  of  Mineral  Resources 
(“COREMI”)]  filed  with  the  Third  Federal 
District  Judge  in  Civil  Matters  an  action 
demanding  from  Mexcobre  (La  Caridad)  the 
payment of royalties since 1997.  In December 
2005,  Mexcobre  signed  an  agreement  with 
MGS.    Under  the  terms  of  this  agreement 
the  parties  established  a  new  procedure  to 
calculate  the  royalty  payments  applicable 
for  2005  and  the  following  years,  and  the 
Company paid in January 2006, $6.9 million 
of  royalties  for  2005  and  $8.5  million  as 
payment  on  account  of  royalties  from  the 
third quarter 1997 through the last quarter of 
2004.  On January 22, 2007 the Third Federal

District  Judge  issued  a  ruling  regarding  the 
payment related to the period from the third 
quarter  of  1997  through  the  fourth  quarter 
of  2004.    This  ruling  was  appealed  by  both 
parties  in  February  2007.    The  appeal  was 
lost  by  the  Company  in  October  2007.    The 
Company  filed  a  protective  action  (Amparo) 
before  the  Ninth  collegiate  Civil  Tribunal 
which  rendered  a  negative  ruling  on  August 
27,  2008.    The  Company  is  defending  its 
economic  interest  in  the  judicial  process  to 
determine  the  final  amount  to  be  paid  to 
MGS.    On  an  ongoing  basis  the  Company  is 
required to pay a 1% royalty on La Caridad’s 
copper  production  value  after  deduction  of 
treatment  and  refining  charges  and  certain 
other carrying costs.

San Luis Potosi Facilities: The municipality of 
San Luis Potosi has granted Desarrolladora 
Intersaba, S.A. de C.V. (“Intersaba”) licenses 
for use of land and construction of housing 
and/or commercial zones in the former Ejido 
Capulines  zone,  where  some  residential 
projects  like  “Villa  Magna”  and  other  new 
residential  projects  are  being  developed 
within  an  area  designated  as  a  buffer  zone 
due  to  IMMSA’s  use  of  anhydrous  ammonia 

gas.  This designation as a buffer zone was 
granted by the risk area of SEMARNAT (the 
federal  environmental  authority)  within  its 
approval of the IMMSA’s Risk Analysis.

Regarding this situation, a number of actions 
occurred, including the following:

1) Against  the  municipality  of  San  Luis 
Potosi,  requesting  the  annulment  of 
Desarrolladora  Intersaba’s  authorizations 
and licenses granted within the zinc plant’s 
buffer zone.

In  August  2006,  the  action  regarding  the 
annulment  of  Villa  Magna 
licenses  was 
decided  by  a  federal  appeals  court,  which 
denied IMMSA’s request.  In September 2006, 
IMMSA  submitted  its  final  appeal  to  the 
Supreme  Court  of  Justice  and  in  February 
2007, the court ruled against IMMSA.

IMMSA  believes  that  even  though  the 
outcome  was  adverse  to  its  interest,  the 
construction  of  the  “Villa  Magna”  housing 
and  commercial  development  will  not 
affect the operations of IMMSA’s zinc plant 
by itself.

In November 2008, a local court ruled that 
IMMSA  had  to  pay  $0.9  million  related  to 
this matter.  IMMSA appealed such ruling.  

4) Also,  new  lawsuits  were  filed  by  IMMSA 
against the Municipality of San Luis Potosi 
challenging  other  licenses  granted  in  the 
safeguard area.

2) In  addition  to  the  foregoing,  IMMSA  has 
initiated a series of legal and administrative 
procedures  against  the  Municipality  of  San 
Luis Potosi due to its refusal to issue IMMSA’s 
use of land permit (licencia de uso de suelo) 
in respect to its zinc plant.  A federal judge 
ruled that IMMSA’s use of land permit should 
be  granted.    The  municipal  authorities 
confirmed  on  February,  2009  that  the 
applicable local regulation allows IMMSA to 
use the land for industrial purposes. 

3) Additionally, Ejido Capulines, an agricultural 
community,  filed  a  protective  action 
against  IMMSA’s  Risk  Analysis  approved 
by  SEMARNAT.    As  previously  noted,  this 
approval determines a buffer zone around 
the San Luis facilities.

  On  November  4,  2008,  a  Federal  Judge 
considered that the Ejido Capulines did not 
demonstrate any harm caused by IMMSA´s 
Risk Analysis Authorization. On December, 
2008  the  Ejido  Capulines  appealed  the 
decision on the Federal Court Jurisdiction.

5) IMMSA filed on October 7, 2008 a lawsuit 
against SEMARNAT before the Federal Tax 
and  Administrative  Justice  Court  seeking 
the  nullity  of  a  July  24,  2008  denial  of 
the  Company’s  request  for  a  safeguard

which  she  argued  the  accident  should 
trigger.

The First District Administrative Judge flatly 
dismissed the case, but this ruling was later 
revised by an appeals court.  Mrs. Martinez 
filed  a  new  protective  action  against  a  new 
ruling  issued  by  the  Ministry  of  Economy.  
The  Company  is  certain  that  an  accident 
cannot  trigger  a  procedure  of  cancellation 
of  the  coal  concessions.    Although  the 
Company  cannot  predict  the  outcome  of 
the  procedures  filed  by  Mrs.  Martinez,  the 
Company  asserts  that  the  claims  of  Mrs. 
Martinez are without merit and is vigorously 
defending against the actions.

PeruviaN OPeratiONS

The  Company’s  operations  are  subject  to 
laws 
applicable  Peruvian  environmental 
and regulations.  The Peruvian government, 
through  its  Ministry  of  Energy  and  Mines 
(“MINEM”)  conducts  annual  audits  of 
the  Company’s  Peruvian  mining  and 
metallurgical  operations.    Through  these 
environmental  audits,  matters  related  to 

legal 

environmental  commitments,  compliance 
with 
requirements,  atmospheric 
emissions,  and  effluent  monitoring  are 
reviewed.  The Company believes that it is in 
material compliance with applicable Peruvian 
environmental laws and regulations.

In  2003,  the  Peruvian  Congress  published 
a  new  law  announcing  future  closure  and 
remediation  obligations  for  the  mining 
industry.    In  August  2006,  in  accordance 
with  this  law  and  its  amendments,  the 
Company  prepared  and  submitted 
to 
MINEM a closure plan.  In March 2008, the 
Company submitted to the MINEM feasibility 
Closure Plan. The MINEM has subjected the 
Closure Plan to public consultation from late 
September until late November 2008. Also 
in November 2008, the Company submitted 
to  MINEM  a  closure  plan  of  the  Marine 
Trestle in the Ilo Smelter area to ship sulfuric 
acid, as part of a legislative requirement to 
submit  one  year  after  the  approval  of  the 
Environmental  Impact  Studies.  The  Marine 
Trestle is under construction. 

In  addition,  the  Company  has  initiated  the

activities  in  those  countries  and  Chile.    Our 
operations make us one of the largest mining 
companies in Peru and also in Mexico.  We are 
one of the largest copper mining companies 
in the world with significant copper reserves.  
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 also produce significant 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  984  kilometers  southeast 
of the city of Lima, Peru.  We also operate a 
smelter  and  refinery  west  of  the  Toquepala 
and  Cuajone  mines  in  the  coastal  city  of  Ilo, 
Peru.

Our  Mexican  operations  are  conducted 
through  our  subsidiary,  Minera  Mexico  S.A. 
de C.V. (“Minera Mexico”), which we acquired 
on  April  1,  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.  Mexicana de Cananea 
S.A.  de  C.V.  (together  with  its  subsidiaries, 
the  “Cananea  Unit”)  operates  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.  Industrial Minera Mexico, S.A. de 
C.V. and Minerales Metalicos del Norte, S.A. 
(together  with  its  subsidiaries,  the  “IMMSA 
Unit”) operate five underground mines that 
produce zinc, lead, copper, silver and gold, a 
coal  mine  and  several  industrial  processing 
facilities for zinc and copper.

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

DESCRIPTION OF OPERATIONS AND DEVELOPMENT 
REGARDING THE ISSUING ENTITY

PURPOSE
The  purpose  of  Southern  Copper  Corporation  (SCC)  is  to  engage 
in  activities  allowed  by  the  laws  of  the  State  of  Delaware.    Its  main 
activity is to extract, mill, concentrate, smelt, treat, prepare for market, 
manufacture, sell, exchange and, in general, to produce and negotiate for 
sales of copper, molybdenum, gold, silver, lead, zinc, iron and any other 
class of minerals and materials or other materials, effects and goods of 
any nature or description; as well as to explore, exploit, sample, examine, 
investigate, recognize, locate, appraise, buy, sell, exchange, etc., mining 
concessions and mining deposits. SCC belongs to the CIIU 1320 group.  

The term of duration of the Company is indefinite.

BRIEf hISTORICAL REVIEw fROM ThE CONSTITUTION

Of ThE COMPANy:

The Company was organized on December 12, 1952, according to the 
Laws of the State of Delaware of the United States of America, under 
the original denomination of Southern Peru Copper Corporation 
(“SPCC”), which was renamed on October 11, 2005, to Southern Copper 
Corporation (SCC).  

In 1954, SCC established a Branch in Peru to carry out mining activities 
in this country. The Branch was established under public instrument 
certified by Public Notary from Lima, Dr. Ricardo Fernandini Arana, on 
November 6, 1954.

The Branch is registered in the Electronic Record No. 03025091 of the 
Juridical People of the Registry Office of Lima and Callao.

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.  It  was  made  through  money  contribution  by  the  Company 

59 59 

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  was  aimed  at  increasing  the  capital 
allotted to the Branch by the headquarters and 
registered  in  Peru.  The  capital  contribution 
made  by  the  Labor  Shares  (today  Investment 
Shares)  owners  was  assigned  to  the  Labor 
Shares account of the Branch for issuing new 
Labor Shares. 

Part  of  the  money  contribution  made  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.

1995, 

Exchange  of  Labor  Shares  for  Common 
Shares:
Dated  September  7, 
“Southern 
Peru  Copper  Holding  Company”  was  also 
incorporated pursuant to the Laws of the State 
of  Delaware,  aiming  at  acting  as  a  holding 
company that owns all Southern Peru Copper 
Corporation  shares,  and  at  performing  an 
exchange of the shares that were then called 
“Labor  Shares”  (today  Investment  Shares) 
issued  by  the  branch  in  Peru,  delivering  the 
owners  of  labor  shares  a  certain  number 
of  common  shares  issued  by  SPCC  in  the 
United  States.  As  a  consequence  of  this 
share  exchange,  ex-owners  of  Labor  Shares 
acquired    17.31%  of  SPCC’s  Capital,  and  this 
company  acquired  ownership  of  80.77%  of 
Labor Shares (today Investment Shares).

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.

As  a  consequence  of  this  corporate  name 
change, the mining activities of the Company 

in  Peru  started  being  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 one 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  Net  Worth  Share 
Account (investment shares), which were kept 
the unchanged. 

As a consequence of the merger, the mining 
activities  of  the  corporation  in  Peru  were 
again carried out 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 Stated 100% of ASARCO Incorporated, 
the  main  shareholder  of  Southern  Peru 
Copper Corporation at that time. In this way, 
SPCC became a subsidiary of Grupo Mexico, 
who keeps its shareholding through Americas 
Mining Company (AMC).

Acquisition of Minera Mexico, S.A. de C.V. 
(“MM”) and other corporate changes:
S CC   s h a re h o l d e r s ,   i n   a   s h a re h o l d e r 
extraordinary meeting dated March 28, 2005, 
approved 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 for more than 90% of the stocks 
and circulating capital of SCC. To acquire MM, 
SCC issued 67,207,640 shares in exchange 
for MM shares. Once the shares related to 

60 - 61 
61 

SOUTHERN COPPER 2008

the acquisition were issued, Americas Mining 
Corporation increased its share in SCC from 
54.2% to approximately 75.1%.

SCC $500 Million Share Repurchase 
Program:
In 2008, the Company’s Board of Directors 
authorized a $500 million share repurchase 
program. During 2008 the Company purchased 
28.5 million shares of its common stock at a 
cost of $384.7 million. These shares will be 
available for general corporate purposes. The 
Company may purchase additional shares 
from time to time, based on market conditions 
and other factors. This repurchase program 
has no expiration date and may be modified 
or discontinued at any time.

Americas Mining Corporation Increased its 
Participation in SC:
I n   2 0 0 8   G r u p o   M e x i c o ,   t h r o u g h   i t s 
wholly owned subsidiary AMC, purchased 
approximately  11.8  million  shares  of  the 
Company’s common shares. As a result of 
these transactions Grupo Mexico’s ownership 
of SCC’s outstanding capital stock increased 
from  75.1%  to  79.0%1 at  December  31th, 
2008.

Change in the Certificate of Incorporation:
O n   M a rch   28 ,   20 0 5 ,   fo llowin g   B o a rd

of   I n co r p o ratio n   D e e d ,   cha n g i n g   th e 
composition and obligations of some Board 
committees.

Special Independent Director:
The changes to the Articles of Incorporation 
Deed require the Board to include a certain 
number of special independent directors. 
A special independent director is a person 
who  (i)  complies  with  the  independence 
standards of the New York Stock Exchange 
(or any other stock exchange or association 
in which Common Shares are listed) and (ii) 
is appointed by the Special Appointment 
C o m m i t t e e   o f   t h e   B o a r d .   A   s p e c i a l

its affiliates) have, rounding up to the following 
integer whole number. Notwithstanding the 
abovementioned, the total number of people 
appointed as special independent directors 
(not belonging to Grupo Mexico) cannot be less 
than two or more than six.

Special Nominating Committee:
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 number of special independent 
directors  based  on  the  percentage  of  our 
Common  Stock  owned  by  all  holders  of  our 
Common Stock, other than Grupo Mexico and 
its affiliates.

The  Special  Nominating  Committee  consists 
of  three  directors,  two  (2)  of  whom  are  Luis 

Miguel  Palomino  and  Carlos  Ruiz  Sacristan 
(each  an  “Initial  Member”  and,  together  with 
their  successors,  “Special  Designees”)  and 
such other director, currently Xavier Garcia de 
Quevedo Topete, as may be 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. 

Our  Amended  and  Restated  Certificate  of 
Incorporation, as amended, provides that the 
number  of  special  independent  directors  on 
the Board of Directors at any given time shall 
be  equal  to  (a)  the  total  number  of  directors 
on the Board of Directors multiplied by (b) the 
percentage of Common Stock owned by all of 
the  stockholders  (other  than  Grupo  Mexico 

Flotation cells in Toquepala concentrator, Peru

and its affiliates), rounded up to the next whole 
number.  Notwithstanding  the  foregoing,  the 
total number of persons nominated as special 
independent directors cannot be less than two 
or greater than six.  

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:
Amendments  to  the  Deed  also  prohibit 
the  Company  to  commit 
important 
transactions  with  the  affiliates,  except 
if  the  transaction  has  been  revised  by  a 
committee of at least three Board members, 
each one of which will comply with the New 
York  Stock  Exchange  (or  any  other  stock 
exchange  or  association  in  which  Common 
Shares are listed) independence regulations. 
An  important  transaction  of  the  affiliate 
is  defined  as  an  important  transaction, 
commercial negotiation or financial share in 
any  transaction,  any  series  of  transactions 
between Grupo Mexico or one of its affiliates 
(different  from  the  Company  or  any  of  the 
subsidiaries),  on  the  one  hand,  and  to  the 
Company or one of the subsidiaries, on the 
other hand, comprising a total consideration 
of more than $10’000,000.00.

The Company submitted the Amendment of its 
Articles of Incorporation Deed to the Secretary 
of State in the State of Delaware, and it came 
into effect as from March 31, 2005 at 11:59 P.M.

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 
the corporate name change of Southern Peru 
Copper  Corporation  to  Southern  Copper 
Corporation or SCC. The change was adopted 
because the new corporate name reflects 
more precisely the Company’s operations 
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. 

Additionally, on the same date, the majority 
shareholder approved an amendment of our 
Articles of Incorporation Deed to  remove 
others’ provisions in our Deed related with 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 
following agreement of most of Board members 
stipulating the number of directors will not be 
less than six or more than fifteen. 

The Deed amendment was submitted to the 
Secretary of State of the State of Delaware, 
and came into effect on October 11, 2005.

Peru Branch Name:
Generally, the change of headquarters corporate 
name 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, taking into consideration 
the net worth and assets importance of the 
Branch, the need to continue acknowledging 
the position of the Peruvian Branch with its 

63 63 

local and international copper clients, the 
need to preserve its proceeds and its position 
in good name in the copper market, and the 
need to prevent any possible client loss, as 
well as to guarantee the revenue flow from 
sales, its financial and economic revenues and 
its solvency, the Board of Directors agreed to 
maintain the original corporate name to the 
Peru Branch, that is, Southern Peru Copper 
Corporation, Peru Branch, or the abbreviated 
name “Southern Peru” and/or the acronym 
SPCC.

Changes in the Certificate of Articles of
Incorporation and Bylaws:
Dated January 26, 2006, the Board approved 
amendment to Southern Copper Corporation’s 
bylaws (i) aiming at removing the provisions 
related to Class A Common Shares among other 
changes.(ii) adding 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.  Because the required vote 
for the approval of this proposal was 80% 

and  because  there  were  still  votes  that 
needed to be tabulated, the annual meeting 
for this proposal was adjourned until May 
4, 2006.  On May 4, 2006, at the adjourned 
and reconvened meeting the stockholders 
approved the proposal with an affirmative 
vote of 80.61% of the required votes.

On April 27, 2006, stockholders approved (i) 
the amendment to the by-laws to introduce 
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); (ii) the amendment to the by-laws 
to  substitute  Grupo  Mexico  for  ASARCO 
Incorporated  in  the  “Change  in  Control” 
definition in the Corporation’s by-laws; (iii) the 
amendments to the Amended and Restated 
Certificate of Incorporation to increase the 
number of shares of Common Stock, which 
the Corporation is authorized to issue from 
167’207,640 shares to 320’000,000 shares; 
and (iv) the selection of the independent 
accountants.

On April 27, 2006, the proposal to amend the 
by-laws to eliminate the 80% supermajority 
vote requirement for certain corporate actions 
had received preliminary votes, representing 
an affirmative vote of 78.35% of the required 
votes.  Because the required vote for the 
approval  of  this  proposal  was  80%  and 
because there were still votes that needed 
to be tabulated, the annual meeting for this 
proposal was adjourned first until May 4, 2006, 
and subsequently until May 11, 2006.   On May 
11, 2006, at the adjourned and reconvened 
meeting stockholders did not approve the 
proposal having received an affirmative vote of 
79.61% of the required votes.

SCC is indirectly, part of Grupo Mexico S.A.B. 
de C.V. which owns 100% of Americas Mining 
Corporation (AMC) shareholding, owner of 
79.0% of SCC shares.

MExICAN OPERATIONS 

A  key  element  of  our  business  philosophy  is  “Safety  is  a  first  and 
an  essential  part  of  our  operations”.    We  are  committed  to  the 
welfare of our employees and it is the basis for the implementation 
of the Safety and Health Administration System at Work, known by its 
Spanish acronym SIASST. SIASST focuses on safe workplaces and the 
performance of work in a safe manner. 

With the implementation of the SIASST before the end of 2008, all 
our  Minera  Mexico  mines,  plants  and  refineries  signed  agreements 
to voluntarily opt to join the Labor and Social Insurance Secretariat’s 
(STPS),  Self  Safety  and  Health  Program  at  Work.  This  program 
promotes  the  establishment  of  administration  systems,  based  on 
national and international standards, to encourage the operation of 
work centers with safety and hygiene.

Through this program, the STPS gives awards at three different levels, 
and our Company’s Minera Mexico operations were entitled to the third 
recognition, “Safe Company”, as its work accident rates were below the 
national average and, in addition, had the following achievements:

66 - 67

SOUTHERN COPPER 2008

1) Compliance with regulations on safety and 
health. 
2)  Actions  of  continuous  improvement  in 
safety and health. 
3) Accomplishments in the administration of 
safety and health at work. 

Also,  once  the  implementation  phase  of 
the  SIASST  is  concluded,  which  considers 
implementing  an  administration  system  of 
safety and health, the Company will move in a 
continuous improvement process and obtain 
the OSHA 18001 certification.

Part  of  the  results  of  the  implementation 
of  the  SIASST  has  been  the  reduction  of 
accidents  at  Minera  Mexico’s  operations  in 
2008,  which  decreased  by  28.66%  in  total 
accidents and 36.89% in disabling accidents, 
when compared to 2007. In respect to safety 
indicators  in  2008,  Minera  Mexico  achieved 
a reduction of: 22.13% in the frequency rate, 
3.95%  in  the  severity  rate,  and  25.58%  in 
the  loss  rate,  all  compared  to  2007.    As  for 
fatalities,  unfortunately  the  results  were 
similar to 2007 with three recorded cases.

PERUVIAN OPERATIONS

The Safety and Health results in 2008, for 
the open pit mining operations in Toquepala 
and Cuajone mines, metallurgical operations 
in Ilo Unit, which includes a smelter and 
refinery plants, are as follows: Frequency 
I n d e x   1 .9,   S e v e r i t y   I n d e x   1 7 2 .9   a n d 
Accidentability rate 0.3. These indicators 
correspond  to  18  lost  time  accidents.  In 
2008, no fatal accidents were registered. 
The Ilo Unit received In 2008 the “John T. 
Ryan” Award from MSA, offered to the best 
security indicators in mining operations in 
Peru. The evaluators for this award were:  
the General Mining Director from Ministry 
of   En e rg y   a n d   M i n e s   (“ M I N EM ” ),   th e

La Caridad Metallurgic Compound
Copper  concentrates  from  Cananea  and  La 
Caridad  are  transported  by  rail  and  truck, 
respectively, to the La Caridad smelter where 
they are processed and cast into copper anodes 
of  99.2%  purity.    Sulfur  dioxide  off-gases 
collected  from  the  flash  furnace,  Teniente 
converter  and  conventional  converters  are 
processed into sulfuric acid, at two sulfuric acid 
plants.  Approximately 2% to 3% of this acid is 
used by our SX/EW plants and the balance is 
sold to third parties.

Almost  all  of  the  anodes  produced  in  the 
smelter  are  sent  to  the  La  Caridad  copper 
refinery.  The actual installed capacity of the 
smelter is 1’000,000 tons per year, a capacity 
that is sufficient to treat all the concentrates 
of  the  La  Caridad  and  Cananea  mining 
complexes.    The  smelter  includes  a  flash 
type concentrates drier, a steam drier, a flash 
furnace,  one  El  Teniente  modified  converted 
furnace,  two  electric  slag-cleaning  furnaces, 
three Pierce-Smith converters, three rafinnate 
furnaces and two casting wheels.  The anode 
production capacity is 300,000 tons per year.

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

The  operations  of  the  precious  metal 
refinery  are  divided  into  two  stages:  (i) 
the  antimony  is  eliminated  from  the  slime, 
and  (ii)  the  slime  is  dried  in  a  steam  dryer.  
After  this  the  dried  slime  is  smelted  and  a 
gold  and  silver  alloy  is  obtained,  which  is 
known as dore.  The precious metal refinery 
plant  has  a  hydrometallurgical  stage  and  a 
pyrometallurgical  stage,  besides  a  steam 
dryer,  dore  casting  system,  Kaldo  furnace, 
20  electrolytic  cells  in  the  silver  refinery, 
one  induction  furnace  for  fine  silver,  one 
silver ingot casting system, two reactors for 
obtaining  fine  gold.    The  process  ends  with 
the refining of the gold and silver alloy.

Rod Plant
A  rod  plant  at  the  La  Caridad  complex  was 
completed in 1998 and reached its full annual 
operating capacity of 150,000 tons in 1999.  
The  plant  is  producing  eight  millimeter 
copper  rods  with  a  purity  of  99.99%.    The 
rod  plant  includes  a  vertical  furnace,  one 
retention furnace, one molding machine, one 
laminating machine, one coiling machine and 
one coil compacter.

circuits.  The concentrator plant has a milling 
capacity of 1,450 tons of ore per day.

Taxco
The  Taxco  mining  complex  is  located  on  the 
outskirts of the city of Taxco in the northern 
part of Guerrero State, Mexico, approximately 
71  kilometers  from  the  city  of  Cuernavaca, 
Morelos, where access through the highway to 
the complex is possible.  The complex includes 
several  underground  mines  (San  Antonio, 
Guerrero and Remedios) and a flotation plant 
and produces lead and zinc concentrates, with 
some amounts of gold and silver.  The mining 
district  in  which  the  Taxco  mines  are  located 
was discovered in 1519.  Mining activities in the 
20th century commenced in 1918.  The Taxco 
district lies in the northern part of the Balsas-

The Nueva Rosita coal and coke complex
The  Nueva  Rosita  coal  and  coke  complex, 
which began operations in 1924, is located in 
the state of Coahuila, Mexico on the outskirts 
of  the  city  of  Nueva  Rosita  near  the  Texas 
border.    It  includes  a)  an  underground  coal 
mine,  which  has  been  closed  as  a  result  of  a 
gas explosion in February 2006; b) an open pit 
mine with a yearly capacity of approximately 
350,000 tons of coal; c) a coal washing plant 
completed in 1998 with a capacity of 900,000 
tons  per  year  that  produces  clean  coal  of  a 
higher  quality;  and  d)  a  re-engineered  and 
modernized  21  coke  oven  facility  capable  of 

producing 105,000 tons of coke (metallurgical, 
nut  and  fine)  per  year  of  which  95,000  tons 
are  metallurgical  coke.    There  is  also  a  by-
product  plant  to  clean  the  coke  gas  oven  in 
which  tar,  ammonium  sulfate  and  light  crude 
oil  are  recovered.    There  are  also  boilers  to 
produce 80,000 steam pounds that are used 
in the by-products plant.  The re-engineering 
and modernization of 21 ovens was completed 
in April, 2006 and it is presently operating with 
no problems to report.

At present, the coke oven installation supplies 
the San Luis Potosi copper smelter with low-
cost coke, resulting in significant cost savings 
to the smelter.  The surplus production is sold 
to  Peñoles  and  other  Mexican  consumers  in 
northern  Mexico.    We  expect  to  sell  37,438 
tons of metallurgical coke in 2009.

Zinc Refinery
The San Luis Potosi electrolytic zinc refinery 
was built in 1982.  It was designed to produce 
105,000 tons of refined zinc per year by treating 
up to 200,000 tons of zinc concentrate from 
our own mines, principally Charcas, located only 
113 kilometers from the refinery.  The refinery 
produces  special  high  grade  zinc  (99.995%

zinc),  high  grade  zinc  (over  99.9%  zinc)  and 
zinc-based alloys with aluminum, lead, copper 
or magnesium in varying quantities and sizes 
depending on market demand.

The electrolytic zinc refinery’s major equipment 
includes  a  roaster  with  a  capacity  of  85  m2 
of roasting area, a steam recovery boiler and 
an  acid  plant.    There  is  a  calcine  processing 
area  with  five  leaching  stages:  neutral,  hot 
acid,  intermediate  acid,  acid,  purified  fourth 
and jarosite, as well as two stages for solution 
purifying.  Additionally, the equipment includes 
a  cell  house  with  two  electrowinning  circuits 
to  finally  obtain  metallic  zinc;  an  alloy  and 
molding area with two induction furnaces and 
four molding systems, two of them with chains 
to produce 25 kilogram ingots; and two casting 
wheels to manufacture one ton Jumbo pieces.  
This  refinery  has  a  production  capacity  of 
105,000 tons of refined zinc per year.

Smelter
The San Luis Potosi copper smelter has been 
in operation since 1925 and has gone through 
several  phases  of  modernization,  principally 
over the last ten years.  The smelter presently 
has the capacity to process 230,000 tons of 
copper concentrate per year.

The  plant  operates  one  blast  furnace  (with 
a  second  on  stand-by)  that  smelts  incoming 
materials,  mainly  copper  concentrates  and 
copper by-products from lead plants, to produce 
a copper matte.  The copper matte is then treated 
in  one  of  the  two  Pierce  Smith  converters, 
producing  copper  blister  (95.7%  copper), 
which  in  2008  contained  approximately  2.1 
ounces  of  gold  and  360  ounces  of  silver  per 
ton  of  copper  blister  produced.    Of  a  total 
copper  concentrate  intake  of  40,878  tons  in 
2008, approximately 29% was supplied by the 

IMMSA unit’s mines and the remaining amount 
was purchased from third parties.  25% of the 
blister  production  is  sold  to  the  La  Caridad 
copper smelter and the remaining 75% is sold 
to third party refineries throughout the world.

The  San  Luis  Potosi  copper  smelter’s 
equipment 
locomotives, 
include  two  yard 
two  drag-shovels,  twenty  dump  cars  and  six 
mechanic front loaders for the furnace charge 
mixing.  Smelting  and  conversion  equipment 
include three blast furnaces, two Pierce Smith 
converter furnaces, two molding furnaces, six 
electric  front  loaders,  six  towing  units,  three 
narrow  way  locomotives,  two  bridge  cranes, 
two  7-ton  cranes  and  three  hoists.    Venting 
system  equipment  includes  nine  fans  with 
different  capacities  and  two  filtering  bag 
houses.  This plant has a smelting capacity of 
24,000 tons of blister copper per year.

SCC filed a Registration Statement on Form

Corporate Bonds
On May 9, 2006, SCC issued $400 million 
7.5% Notes due 2035. On July 27, 2005, SCC

On January 3, 2006 the Company completed 
an exchange offer for $200 million, 6.375% 
Notes  due  2015  and  $600  million,  7.5% 
Notes due 2035. In the exchange offer, $197.4 
million of the 6.375% old notes due 2015 
were tendered in exchange for an equivalent 
amount of new notes and an aggregate of 
$590.5 million of the 7.5% old notes due 
2035  were  tendered  in  exchange  for  an 
equivalent amount of new notes. The new 
notes have been registered under the U.S. 
securities law. The indentures relating to the 
notes contain certain 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. 
All of these limitations and restrictions are 
subject to a number of significant exceptions, 
and some of these covenants will cease to 
be applicable before the notes mature if the 
notes attain an investment grade rating. At 
December 31, 2008, we are in compliance with 
these covenants.

In January 2005, the Company signed a $200 
million credit facility with a group of banks 
led by Citibank, N.A. Proceeds of this credit 
facility were used to prepay $199 million the 
outstanding bonds of the Company’s Peruvian 
bond program. On July 28, 2005, a portion of 
the proceeds from the financing, noted above, 
were used to repay this facility.

In 1998, Minera Mexico issued $500 million of 
unsecured debt, which we refer to as its Yankee 
bonds. The Yankee bonds were offered in two 
series: Series A for $375 million, with an interest 
rate of 8.25% and a 2008 matu-rity date, and 

Series B for $125 million, with an interest rate 
of 9.25% and a 2028 maturity date. During 
2006 and 2005, the Company repurchased 
$23.3 million and $143.0 million of the Series 
A bonds, respectively. The 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 
by the bonds. At December 31, 2008, Minera 
Mexico is in compliance with this covenant.

In 1999, the Company established a $100 
million credit facility with Mitsui & Co. The 
facility has a 15-year term with an interest 
rate of Japanese LIBO plus 1.25% (Japanese 
LIBO for this loan was 2.32% at December 
31, 2008). The facility is collateralized by the 
assignment of copper sales receivables of 
31,000 tons of copper per year and requires an 
escrow account to fund scheduled payments. 
The  facility  requires  that  we  maintain  a 
minimum stockholders’ equity of $750 million 
and a ratio of debt to equity no greater than 
0.5 to 1.0, all as such terms are defined by the 
facility. Reduction of Grupo Mexico’s direct or 
indirect voting interest in our Company to less

than a majority would constitute an event of default under the facility. 
At December 31, 2008, we are in compliance with these covenants.

On October 29, 2004, Minera Mexico borrowed $600 million pursuant 
to a facility with a final maturity date in 2009. The credit facility bore 
interest at LIBOR plus 200 basis points. The proceeds from the credit 
facility were used to repay in full the amounts outstanding under a 
common agreement with holders of Minera Mexico’s secured export 
notes and other financial institutions. The loan was secured by a 
pledge of Minera Mexico’s principal properties and was guaranteed 
by its principal subsidiaries. In 2005, the Company prepaid the total 
amount of this financing, using in part proceeds from the July 27, 
2005 Note issuance.

We expect that we will meet our cash requirements for 2009 and 
beyond from internally generated funds, cash on hand and from 
additional external financing if required.

Messrs. German Larrea  Mota-Velasco,  Chairman  of  the Board 
of  the  Company  and  Genaro  Larrea  Mota-Velasco,  a  Director 
of  the  Company  are  brothers  or  kindred  in  second  degree  of 
consanguinity. 

A company of which more than 50% of the voting power is held by 
a single entity, a “controlled company”, need not comply with the 
requirements of the New York Stock Exchange (“NYSE”) corporate 
governance rules requiring a majority of independent Directors and 
independent compensation and nomination/corporate governance 
committees.  SCC is a controlled company as defined by the rules 
of the NYSE. Grupo Mexico owns indirectly 78.97% of the stock of 
the Company.   The Company has taken advantage of the exceptions 
to comply with the corporate governance rules of the NYSE.  The 
Board of Directors of the Company determined that Messrs. Luis 
Miguel Palomino Bonilla, Gilberto Perezalonso, and Emilio Carrillo, 
the  three  members  of  the  Company’s  Audit  Committee,  are 
independent of management and financially literate in accordance 
with the qualifications of the NYSE and the Securities and Exchange 
Commission (“SEC”), as such qualifications are interpreted by the 
Company’s Board of Directors in its business judgment.  In 2008 
we had four special independent directors nominated by the Special 
Nominating Committee, Messrs. Harold S. Handelsman, Luis Miguel 
Palomino  Bonilla,  Gilberto  Perezalonso  Cifuentes,  and  Carlos 
Ruiz Sacristan.  In 2008, Mr. Emilio Carrillo Gamboa was our fifth 
independent director. At its meeting on January 24, 2008, the Board 
of Directors determined that Messrs. Harold S. Handelsman, Luis 
Miguel Palomino Bonilla, Gilberto Perezalonso Cifuentes, Carlos 
Ruiz Sacristan and Emilio Carrillo Gamboa were independent of 
management in accordance with the requirements of the NYSE as 
such requirements are interpreted by our Board of Directors in its 
business judgment.

To the best of the Company’s knowledge, no other relationship of 
affinity and/or consanguinity exists among the other members of 
the Board, and between them and the Executive Officers of Southern 
Copper Corporation.
