SOUTHERN COPPER CORPORATION
2005 has been an extraordinary year for Southern Copper Corporation
(SCC) (formerly named Southern Peru Copper Corporation). On April 1,
2005, we completed the acquisition of Minera Mexico with the issuance of
an additional 67.2 million shares of common stock to our principal share-
holder, Grupo Mexico. With this acquisition we have almost doubled the
size of our Company and more then doubled our mineral reserves. Our
sales reached $4.1billion and net earnings were $1.4 billion, an increase
of 32.8% and 42.5% respectively as compared with 2004.
These record results are mainly due to the higher metal prices as well as a
reduction in operating costs, and reflect our commitment to be a more ef-
ficient mining operation and a more integrated company.
We would like to highlight the strength of our balance sheet, as evidenced
by an increase of US$512.5 million, or 18.2%, in stockholder’s equity, a
decrease of US$158.2 million in long-term debt and an increase in
US$120.0 million in cash and marketable securities.
In 2005, average market prices for our main products increased signifi-
cantly over 2004. The COMEX average copper price was $1.68 per pound
in 2005, compared to $1.29 in 2004, an increase of 30.4%. The zinc aver-
age price was $0.63 per pound, 31.9% higher than the $0.48 per pound,
from the previous year. The silver average price was US$7.32 per pound,
9.6% higher than the $6.68 recorded in the previous year. The gold aver-
age price was $444.88 per ounce, an 8.7% increase compared with
$409.21 in 2004. The molybdenum average price was US$31.05 per
pound, 94.7% higher than the $15.95 recorded in 2004.
Given the price strength of our main product, copper, we have not acquired
copper hedges for 2006 or future years. Based on copper consumption
growth, the improvements in metal prices, our estimates, general market
and independent analysts expectations, we have taken this position as we
believe this will permit SCC to retain the entire benefits from copper prices.
The Ilo Peru smelter modernization project is moving ahead on schedule
with detailed engineering completed and construction work in process in

order to finish by the end of 2006. The anode casting wheel part of this project was successfully hot tested in the first
quarter of 2006 replacing Ilo blister production with anodes. We now directly feed the refinery and have eliminated
the re-melting of blister into anode form. We estimate that this will save the Company two cents per pound in our
smelting and refining cost at the Ilo operations. At December 31, 2005, the smelter project has reached 64% comple-
tion. Additionally, the Company’s leaching dumps, crushing and conveying project at the Toquepala mine is in pro-
duction. The primary crusher was placed in operation in August. The overland conveyors 1, 2 and 3, and the grass-
hoppers 30 and 31 were put on the production line. The conveying system reached its rated capacity of 6,500 ton/hr
at the end of September 2005. The construction of the ramp will continue until completion in August 2006.
Regarding exploration activities in Peru, the drilling program at our promising Los Chancas project was concluded.
The process for the pre-feasibility study has been started and should be completed by July 2006. The drilling pro-
gram at Tia Maria was completed in March 2006 and we have begun the economic evaluation of the project.
The Cananea mine’s new SX/EW plant project is currently underway. In its first stage, it is expected to produce
10,500 tons of additional copper by the end of 2007. Studies for a 22,900 ton subsequent expansion of the SX/EW
plant are also being underway As the Cananea min has the largest quantity of our copper reserves, we are studying
several possibilities for expanding it to a scale that fully maximizes its potential.
We continue to integrate aspects of our Peruvian and Mexican facilities to achieve operational synergies. We are
working to achieve additional economic benefits as we further integrate our operations utilizing best practices
throughout our Peruvian and Mexican operations. In December 2005, a team from our Peruvian and Mexican opera-
tions and an independent consulting group was formed to review the support operations of the two locations. The
team is responsible for completing this review in 2006, recommending best practice and implementing such recom-
mendation prior to 2007.
Currently, SCC has mining operations in Peru and Mexico and exploration operations in both countries as well as
Chile. The exploration and development of these properties will permit the Company to increase its reserves, as well
as its future prospects.
The projects Southern Copper is executing will consolidate even more our position among the principal metal produc-
ers in the world, which we believe indicates a more satisfactory economic return for shareholders and a greater con-
tribution for the countries and localities where we operate, as well as appropriate benefit for our workers.
On behalf of Southern Copper Corporation’s Board, we express our thanks to all the personnel for their effort, work
and dedication and to our clients for their continued trust and loyalty, and to you, our shareholders, for your perma-
nent support.

Expansion and
Modernization
Program
Operations in Peru
Ilo Unit, casting wheel in smelter, Peru.
Concerning the expansion and modernization programs that have been
taking place in recent years, we can announce the following:
In Toquepala, the Leaching Dumps, crushing and conveying Project
reached 94% progress in December 2005. The new primary crusher was
placed in operations and the overland conveyors 1, 2 and 3, bridge equip-
ment, spreader and first stretch of belt 15 with 3.7 kilometers in length,
started operating. This equipment is being used to make the ramp that will
provide access to leacheable deposit formations at level 2875. At the end
of the year, 4.5 million tons of waste material were deposited and the ramp
construction is estimated to be completed in the third quarter of 2006.
The New PLS Dams Construction Project is being developed. This project
complements the Leaching Dumps Project, since these new deposits will
require new collection dams because the ones existing will be covered by
leachable materials to be deposited in the area. At December 2005, the
project had reached 47% progress. The sedimentation and landslide con-
tention dams were finished. The PLS dam reached 68% progress. In an-
other area of the project, the new power sub-station was completed and is
now under operation. Equipment and materials are currently being sought
for the following stage referring to PLS and raffinate driving lines. This in-
volved essentially pipes and pumps, as well as the acquisition of material
and equipment for a power distribution system at 13.8 Kv.
Studies on possible sites for Tailings Disposal were finished. Analysis of
alternatives were completed and we decided to expand the current Que-
brada Honda dam, using the conventional cycloning method. Engineering
started in December and at the same time the existing auxiliary dikes were
raised two meters to make sure decanted water does not flow towards
Quebrada Santallana.
Regarding the new copper press filter in Toquepala, the installation was
completed and it is in operation since June 2005.
The Ilo Smelter Modernization Project, the new Smelter will use an Isa-
smelt furnace and two rotating furnaces at the copper concentrate fusion
stage to separate matt from slag. The conversion stage will be realized in
four 15 feet diameter and 35 feet long Pierce Smith converters. Out of
these, three will be re-furbished and one will be new. A new Anode Plant,
a new Sulfuric Acid Plant and a new Oxigen Plant will be installed, as well
as the other necessary auxiliary facilities.

ANNUAL REPORT
page 13
SOUTHERN COPPER CORPORATION
Processing capacity will be 1.2 million
tons of copper concentrate per year.
Sulfur capture will be 95%, above cur-
rent environmental legislation require-
ments. The final product of the new
Smelter will be copper anodes instead
of the blister bars that were produced
before.
In 2005, construction works contin-
ued, reaching 64% progress to Decem-
ber 2005. The Acid Plant construction
works reached 46% progress with the
completion of civil works. Current
work is assembly of main equipment.
Oxygen Plant construction works have
progressed by 56%, mechanic assem-
bly is practically finished and electric
and instrumentation assembly was
started. The Anode Plant is almost
finished and cold tests have been per-
formed. Hot tests with refined copper
in the new furnaces were made in
January 2006.
HDPE underground piping and electric duct installation works were fin-
ished; installations for reception of GLP were completed, and are now the
most modern in Peru. The civil works of the new seawater intake are con-
cluded. The civil works for the rest of the project show a 93% progress.
The contract to manufacture and install tanks is 58% completed, pending
still is the installation of 22,500 tons tanks for receiving and storing sulfu-
ric acid produced by the new and existing Acid Plants.
The Isasmelt fusion furnace and the rotating furnaces to separate matte
from slag are already placed on their pedestal shoes and we have been
working on mounting the smelter building structures. Likewise, we have
been installing metallic structures in the feeding hoppers that feed the
Isasmelt furnace and in the electrostatic precipitator area. On the other
hand, we have been working and installing all kinds of ducts for the sys-
tem to manage the collection of gasses of the converters and installing the
other project’s main equipment, such as electric transformers, desalting
plants, among others.
We started obtaining permits to install a maritime terminal to embark the
sulfuric acid that will be produced due to the modernization. The terminal
consists of a pier on the Pacific ocean in the sector called Bahia Tablones
west of the coastal Ilo-Matarani road and the coast, 15 km north of the
city of Ilo and south of the Smelter.
The call for tenders started for the Los Chancas project pre-feasibility
study. We expect to complete such studies on the third quarter of 2006.
Operations in Mexico
Sulfuric Acid Plant Optimization Project at La Caridad Metallurgic
Complex
Optimization of the Sulfuric Acid Plant at La Caridad Metallurgic Complex
was commenced. This will permit us to increase gas management capacity
and ensure fusion content of the Smeltering Plant at 1 million tons of con-
centrate per year.
Acid Plant No. 1 will increase its 223,421 capacity to 240,000 m³ of gases
(dry base) and the increase in Acid Plant No. 2 will be from 190,139 to
220,000 m³ of gases (dry base). Optimization works in both plants were

legislation requirements.
absorption and final absorption tower distributors, as well as the renewal
of fog removers. These optimization works will continue in March 2006.
Power Generation Plant Construction
The Mexico division will invest more than
$600 million to build a new power gen-
eration plant for its own consumption.
The plant will have a generation capacity
of 450 MW per year, using the coal that
comes from its own reserves located in
the state of Coahuila.
The plant will use circulating fluidized
bed technology ensuring clean power
generation, which will comply with every
domestic and international environmen-
tal requirement.
The project will represent considerable
savings in the cost of kw/hr consumed by
mining and metallurgic units in Mexico,
permitting them to have competitive
power and long-term cost certainty. This
will be added to an increase of SCC’s coal
operations in Mexico, which will bring
about more jobs and revenues.
Santa Barbara Unit Expansion
The project consists on expanding the mineral extraction capacity from
inside the mine to the surface with a 1,354 meters conveyor belt. With this
project we will have access to the San Diego mine reserve, which metal
contents are the greatest in all the unit. In 2005, the first 900 meters were
finished. The 454 remaining meters plus the infrastructure needed for ore
transportation will be completed in 2006.
San Martin Unit Shaft Deepening
The two phase project to deepen the unit’s shaft will permit to improve the
extraction of the ore reserves at the least possible cost.
The First phase contemplates sinking 220 meters of shaft and the neces-
sary works for the crusher equipment. All the mining works are completed
and the last days of August 2006 have been fixed as the testing and
startup date.
It will be necessary to deepen interior II shaft in 2007-2008, as well as
building new load installations. 330 shaft meters will be sunk at this
stage, giving the unit’s operation continuity and permitting it to reach the
highest mineral potential level.
Coal Extraction Expansion
SCC Mexican Division has 67 million tons of coal in reserve. In 2005, the
first project stage to increase coal production to 2 million tons per year
was started, this first stage means preparation and exploitation of the
eastern zone with long wall mining system and an estimated production of
900,000 tons.
The second stage contemplates preparing and exploiting the reserves lo-
cated in the Western Zone to reach an additional production of 1.1 million
annual tons.
In 2006, construction works at the new mine will be started to be able to
extract the coal.

Exploration
We are committed with an intense exploration program to locate new miner-
alized bodies in Peru, Mexico and Chile. We spent $24.4 million in explora-
tion programs in 2005, $15.6 million in 2004 and $17.9 million in 2003, and
we have budgeted $33.4 million for 2006.
We currently control 99,537 hectares of mining rights in Peru. In Mexico we
control 505,127 hectares in exploration and exploitation concessions. We
also hold 38,200 hectares of exploration concessions in Chile.
PERU
Los Chancas. The Los Chancas project, located in the department of Apuri-
mac in the south, is a copper and molybdenum porphyry deposit. In 2004,
we completed the final phase of the diamond drilling program and the second
and the final phase of metallurgic testing. In 2005, several companies have
been invited to present proposals for execution of pre-feasibility studies
that will begin in 2006. Once completed, we will be able to make a determi-
nation if more exploration is needed or if the project contains commercially
mineable reserves, which would warrant future development after compres-
sive economic, technical and legal feasibility studies are completed. Testing
to date indicated a mineral deposit of 200 million tons with a copper grade
of 1.0%, 0.07% of molybdenum and 0.12 grams of gold per ton.
Tantahuatay. The Tantahuatay project is located in the department of Caja-
marca, in the north. We have performed exploration work in the upper part of
the deposit, principally for gold recovery. Work to date indicates mineraliza-
tion of 27.1 million tons, with an average gold contents of 0.89 grams per ton
and 13.0 grams of silver per ton. This project, in which we we have a 44.25%
share, continues in the exploratory stage. In 2004 and 2005, we concen-
trated our efforts on dealing with the social and environmental concerns of
communities near the project.
Tia Maria. The Tia Maria project, located in the department of Arequipa, in
the south, is a copper porphyritic system. In 2005, a total of 29,000 meters
of diamond-drilling was completed out of the 15,000 meters initially pro-
jected. The drilling is continuing into 2006 to complete the program. This
project is in the exploratory stage but we expect to commence the feasibility
study in the second quarter of 2006.

Other prospects in Peru. As part of the 2005 exploration and development
program, we programed drilling at the Gloria Cristina prospect, located
in the north of Peru, in the departments of La Libertad and the El Fiscal
prospect, in the south, in the department of Arequipa. The El Fiscal project
shows evidence of copper-gold mineralization and we are scheduling addi-
tional drilling as part of the 2006 exploration and development program.
MEXICO
Drilling programs of 40,500 and 19,000 meters were developed in the Cana-
nea and La Caridad mines, respectively. These projects aim at defining re-
serves and carrying out metallurgic tests to improve recovery at the plants.
The El Arco project, containing measured resource of 846 million tons of a
0.51% sulphide copper grade and 170 million tons of an oxide copper grade
of 0.56%, technical studies were completed to locate 150 liters per second
of fresh water for the SX/EW process. We are currently waiting for the cor-
responding permits to test results with direct drilling.

In the Coahuila state, we continued the exploration activities to identify
additional reserves to the current 67 million tons. In the Guayacan zone
11,714 meters were drilled, showing an important additional potential.
The Environment Secretariat and Natural Resources (SEMARNAT) and Gua-
najuato Ecology Institute permits were obtained to explore for gold, silver,
copper, zinc and lead, in the claim Reduccion Leon located in Sierra de Lo-
bos, Guanajuato.
Likewise, 5,284 meters were drilled at the Morelos Sur project located in
the Guerrero state. Studies show it is still interesting due to its amounts of
gold and silver.
The Company controls 770 claims in exploration totaling 296,227 hectares
with exploration and exploitation rights. However, with the changes in min-
ing legislation as from January 2006, they will only be called mining conces-
sion rights.
Generally, at all these claims, we are carrying out geology, geophysics, in-
spection, exploration, conservation and necessary infrastructure works.
CHILE
In 2003, we bought several explora-
tion properties in Chile with more than
35,000 hectares in mining rights. In
2004, we started exploration works
with diamond drilling in the El Salado
prospect.
El Salado. It is located in the Atacama
region, and occupies a 2,700 hectares
area. It is being explored for copper and
gold mineralization. 11,079 meters of di-
amond drilling were performed in 2005.
Other prospects in Chile. Catanave and
Esperanza, located in the Tarapaca and
Atacama regions, respectively, in the
north of Chile, are programd for explo-
ration in the near future.

Community
Outreach
Operations in Peru
Open pit, Toquepala mine, Peru
Southern Copper substantially stimulates the economy in the south of the
country and is particularly identified with the sustainable development and
wellbeing of the Tacna and Moquegua population, promoting and carrying
out Social Investment actions in the neighboring communities. This is un-
dertaken by co-management with different public entities and the popula-
tion. SCC directs its community outreach to the geographic environment as
a facilitator for social-economic development. Southern Copper is a good
corporate social neighbor and is environmentally responsible. It evidences
this approach through co-participatory projects.
In 2005, SCC developed, among others, the following projects:
• Water resource management: In the Torata valley (Moquegua), the 7th
Stage of the Chilligua canal construction is being completed. At the same
time, we are promoting water use optimization through training and prac-
tical courses to users and the installation of 60 gates, as well as the repair
of the main water intakes. We continued supporting the Torata User Board
logistically and technically so they can participate in local participatory
budgeting. In Candarave (Tacna), the Marisol Water Divide was built. This
will benefit the district of Cairani, Huanuara, Candarave and Quilahuani.
We are also building and rehabilitating minor irrigation infrastructure in
ten Irrigation Committees. In Higuerani, we are exploring the possibility of
drilling a well to draw underground water.
• Agriculture: In Candarave, potato and oregano seed areas were strength-
ened. We also fostered sowing of oat seeds. We continued renewing
alfalfa plantations, by improving water consumption and fostering feed
oat sowing. At the same time we started researching biological greenfly
control. In Torata, we are training producers to grow more profitable crops
for their families. In the Locumba and Ite valleys we are working on irriga-
tion infrastructure.
• Cattle raising: In Candarave, we continued supporting genetic improve-
ment of sheep, promoting cattle raising and dairy industry, as well as the
artificial insemination and cattle stalling programs. In Torata, we provide
technical and animal health assistance. We created the Torata Alta Farm-
ing Producer Association and, together with them, we started a family
farm program for guinea pig raising. In Suches-Huaytire-Tacalaya, we are
starting a genetic research program with South American camelids. At the
same time, we continue working in controlling sarcosistiosis and promot-
ing sale of camelid meat. To do so, we are completing the construction of
a slaughter area in Huaytire. In Higuerani, (Ilabaya-Tacna), the reproduc-

ing guinea pig raising project was
strengthened and we provide perma-
nent technical assistance on animal
health and cattle management to the
different communities devoted to this
field. In Arondaya (Cuajone), we are
continuing a program to develop the
existing subsistance cattle raising so
as to improve raising of camelids,
sheep and goats, by training area
youths in veterinary management.
• Commercial development: In Canda-
rave, we are strengthening the sale of
meat through the Farming Producer
Association made up by the same
cattle raisers who are trained and ad-
vised by SCC technicians. Currently,
their organization
they manage
successfully and have refrigerated
trucks and two equipped stores, one
in Toquepala and one in Cuajone. In
Higuerani, we strengthen a guinea
pig sale channel directly from the
farm to the Toquepala soup kitchens
and concessionaires.
• Basic infrastructure: We channeled
the Locumba river from Ilabaya to
the Locumba bridge. In the Huaytire
alpaca producing zone, we continued
building shelters, reproduction mod-

ules (for controlled population) and fences around paddocks, to facilitate
rational use of pasture.
• Capacity improvement: In Candarave we organized Christmas choir con-
tests. We promoted the organization of youth through Interquorum Net-
work at provincial level.
• Additional activities: We sponsored agricultural fairs in Candarave and
Torata.
In 2005, the results reached by the Company’s Social Program were highly
satisfactory, due, among other things, to daily and permanent sharing of our
technicians with the neighboring communities. This permitted to leverage
their strengths, prioritize their needs, identify their deficiencies and try to
minimize them and, by doing so, we contributed to improve their living condi-
tions and efficiently manage the relationship between our company and the
neighboring areas.

eral athletism events.
IMMSA participates with the San Luis Potosi municipality monthly providing
them more than 50,000 m3 of water by the interconnection of the municipal
network. Besides, it participates in paving streets and sidewalks, as well as in
city landscaping.
CANANEA AND LA CARIDAD UNITS
Cananea and La Caridad participate in promoting the environmental culture
and they are present in different forums on this matter, as well as in commu-
nity non-governmental organizations.
La Caridad Unit has a nursery where trees of different regional species are
grown. They are gratuitously distributed to institutions and individuals, who
simply commit to take care of the trees’ development.
The Cananea Unit contributes with maintaining the Cananea city nursery, with
the same aims as the La Caridad Unit nursery.
Additionally, these Units support the Hermosillo City Ecologic Center, located
in the state of Sonora, and contribute to the conservation of the Mexican Gray
Wolf. This is a wolf species that lives is the region and is endangered.
The emergency brigades of both Units support laboring communities in case
of fire, natural disasters or environmental contingencies. Besides, the Cana-
nea Unit cooperates with the Volunteer Firefighter Body by making preventive
maintenance of their 4 firefighting equipment.
The La Caridad Unit organizes different socio-cultural activities such as
manual workshop, baking, pottery, guitar playing and carpentry. It also orga-
nizes exhibits and talks on pre-school education, children development, and
personal achievement, among others.
On January 6, the La Caridad Unit distributed toys among low income popula-
tion of Esqueda, in the state of Sonora.
The Cananea Unit is totally charged with maintaining the Cananea city public
library, which is classified as the sixth in the state of Sonora. This library

Results of operations for the years ended
December 31, 2005, 2004 and 2003.
SCC reported 2005 net earnings of $1,400.1 million or diluted earnings of
$9.51 per share, compared with net earnings of $982.4 million or diluted
earnings of $6.67 per share in 2004 and $83.5 million or diluted earnings
of $0.57 per share in 2003.
The increase in the Company´ s results for 2005 is due mainly to an increase
in metal prices of our products, which was partially compensated with a re-
duction in the copper sales and silver.
Price of copper during 2005 in the London Metal Exchange (LME) and the
New York Commodity Exchange (COMEX) was of $1.67 and $1.68 per pound
of copper respectively, compared to $1.30 and $1.29 in 2004.
The recent surge in price of molybdenum, principal by-product of SCC, has
had a significant effect on the Company´s traditional calculation of cash
cost and its comparability with prior periods. Accordingly, the Company is
presenting cash costs with and without the inclusion of all by-products reve-
nues. SCC excludes from its calculation of operating cash cost, depreciation,
amortization and depletion, exploration, workers´ participation provisions
and items of a non-recurring nature.
The Company´s operating cash cost, as defined, for the three years ended
December 31, is as follows:

million in 2004 and $1,576.6 million in 2003. Sales increased in 2005 by
$1,015.9 million, a 32.8% increase over the previous year, mainly due to
higher copper, molybdenum, silver and zinc and higher sales of molybde-
num and zinc.
Prices: Sales prices for the Company´ s metals are established principally
by reference to prices quoted in the London Metal Exchange (LME), the New
York Commodity Exchange (COMEX) or published in Platt´s Metals Week, for
dealer oxide mean prices for molybdenum.

Affairs
Peruvian Operations
View of tailings dam, La Caridad Unit, Mexico
Some of the Company’s operations are subject to applicable Peruvian en-
vironmental laws and regulations. The Peruvian government, through its
Ministerio de Energia y Minas (the Ministry of Energy and Mines, or MEM)
conducts certain annual audits of the Company’s Peruvian mining and
metallurgical operations. Through these environmental audits, matters re-
lated to environmental commitments, compliance with legal requirements,
atmospheric emissions and effluent monitoring are reviewed. The Company
believes that it is in material compliance with applicable Peruvian environ-
mental laws and regulations.
In accordance with Peruvian regulations, in 1996 the Company submit-
ted its Programa de Adecuacion y Manejo Ambiental (the Environmental
Compliance and Management Program, known by its Spanish acronym,
PA M A) to the MEM. A third-party environmental audit was conducted in
order to elaborate the PAMA. The PA M A applied to all current operations
that did not have an approved environmental impact study at the time.
SCC’s PA M A was approved in January 1997 and contains 34 mitigation
measures and projects necessary to (1) bring the existing operations
into compliance with the environmental standards established by the
MEM and (2) identify areas impacted by operations that are no longer
active and need to be reclaimed or remediated.
By the end of 2004, 31 of these projects were completed, including all PAMA
commitments related to the Company’s operations in Cuajone and Toque-
pala. The three pending PAMA projects all relate to the Ilo smelter operations.
The primary areas of environmental concern are the smelter reverberatory
slag eroded from slag deposits up until 1994, and atmospheric emissions
from the Ilo smelter.
The slag remediation program is progressing as scheduled and is expected
to be completed by 2007. With respect to the smelter emissions, the third
phase of the Ilo smelter modernization has started and is scheduled to
be completed by 2007. In July 2003, the Company awarded the contract
to provide the technology and basic engineering for the modernization of
the Ilo smelter to Fluor Chile S.A. and Xstrata Plc (formerly M.I.M. Holdings
Limited). The Company believes that the selected technology complies with
the current environmental regulations. This project is the Company’s largest
and most important short-term capital investment project and is estimated
at $500 million, including $389 million expended through December 31st,
2005. Beginning in 1995 and continuing while this project is under construc-
tion, the Company has established an emissions curtailment program that
has allowed the Company to comply with the annual sulfur dioxide air quality
standard (established by the MEM in 1996) in the city of Ilo.

On October 14, 2003, the Peruvian Con-
gress published a new law announcing
future closure and remediation obliga-
tions for the mining industry. The law
was amended on May 28, 2004 and
again on May 8, 2005. The current
modification establishes that mining
companies must submit their mine
closure plans within one year of publi-
cation of final regulations. On August
16, 2005 final regulations were pub-
lished and the Company has initiated
the preparation of the required mine
closure plan. As part of the law and the
qualifying regulations the Company is
also required to engage an indepen-
dent consulting entity to prepare the
mine closure plan. The final plan, which
is required by August 2006, is subject
to approval by MEM and open to public
discussion and comment in the area
of Company operations. Additionally,
the law requires companies to provide
financial guarantees to
insure that
remediation programs are completed.
The Company anticipates that this
law will increase its asset retirement
obligations and require future expen-
ditures and amortizations over the life
of the mine to satisfy requirements. The
The Company’s operations, close to the Mexican-American
border, are also subjected to the Cooperation Agreement
for the Protection and Improvement of the Environment in
the Border Zone
Company believes the liability for these asset retirement obligations can-
not currently be measured, or reasonably estimated, until the Company has
substantially completed its mine closure plan and is reasonably confident
that it will be approved by MEM in its most material respects. However, the
Company has made a preliminary estimate of this liability and has recorded
such amount in its 2005 financial results. The Company foresees significant
environmental capital expenditures in 2006 and continuing into 2007. Dur-
ing 2005, $234.6 million of environmental capital expenditures were made
on the smelter project.
Operations in Mexico
Some Company’s operation activities are subject to federal, state and mu-
nicipal environmental laws, official Mexican standards and regulations for
protecting the environment, including regulations concerning water supply,
water pollution, sound pollution, and solid waste and hazardous waste dis-
posal. Some of these laws and regulations are relevant on matters related to
Company’s facilities in San Luis Potosi.
The main legislation applicable to the Company’s Mexican operations is the
General Law for Ecologic Balance and Environmental Protection. This is a fed-
eral law and is controlled by the Federal Environmental Protection Attorney’s
Office (PROFEPA). PROFEPA monitors compliance with environmental legis-
lation and enforces Mexican environmental laws, regulations and official
standards. If necessary, PROFEPA can file administrative procedures against
companies that violate environmental legislation, which in extreme cases
can result in temporary or permanent close of facilities that do not comply
with provisions, revocation of operation licenses and/or other sanctions and
fines. According to the Federal Criminal Code, PROFEPA must also inform the
corresponding authorities about environmental crimes.
The Company’s operations, close to the Mexican-American border, are
also subject to the Cooperation Agreement for the Protection and Improve-
ment of the Environment in the Border Zone, or La Paz Agreement, signed
in 1983 by the United States and Mexico, aiming at improving air quality
along the border. The La Paz Agreement establishes standards for sulfur
dioxide emissions and requires installing and maintaining emissions moni-
toring systems and information recording in our smelters in the northwest
of Mexico. To comply with sulfur dioxide emission standards, enacted by
the Environment Law and the La Paz Agreement, Minera Mexico closed in
December 1999 the Cananea smelter and the Monterrey operations. The
Mexican environmental regulations has become more strict in the last de-

state of Zacatecas, started the certi-
fication process as a Clean Industry.
• In the Copper Plant located in the
state of San Luis Potosi, as follow-up
to a volunteer proposal of improving
the environment, the Environmental
and Natural Resources Secretariat
authorized the activities to remediate
soils and improve the control of emis-
sions submitted by the Company. The
Company has uninterruptedly worked
to follow up the Actions Detailed Plan
derived from said authorization.
• In the state of San Luis Potosi, there
is a tree nursery, thanks to which
41,371 trees were distributed as
follows: 6,680 for IMMSA division’s
properties; 2,009 for the division
employees and laborers; 11,210 for
community support; 7,149 to sup-

developing trees.
cade and we expect this trend to go on and to be influenced by the environ-
mental agreement signed by Mexico, the United States and Canada related
to the NAFTA, in February 1999. However, the Company’s management does
not consider that continuing compliance with the Mexican Federal or State
Environmental Laws will have a material adverse effect on the Company’s
business, facilities, operation results, financial situation or that it would
result in material capital expenses. Even though the Company considers
that all its facilities comply with environmental, mining and other laws and
regulations, the Company cannot ensure that stricter provisions or that the
current laws and regulations or adoption of new laws and regulations will
not have a material adverse effect on the businesses, properties, operation
results, financial condition or prospects of the Company.
Due to the proximity of some of the facilities of our Mexican operations
subsidiaries to urban areas, the authorities may implement some measures
that could impact or restrict the operation of said facilities. Any use of force
to close any facility may have an adverse effect in the relevant subsidiary’s
operational results.
The Company has established broad environmental conservation programs
at its mining facilities of Peru and Mexico. The Company’s environmental
programs include water recovery systems to preserve the resource and mini-
mize pollution of nearby water sources, reforestation programs to stabilize
surfaces of tailings dams and implementing clean technology at the mines to
reduce dust emissions.
IMMSA Division
• At the Zinc Refinery located in the San Luis Potosi state, we requested the
Environmental and Natural Resources Secretariat (SEMARNAT), to start a
procedure to declare the areas around the refinery as Safeguard Interme-
diate Zone (ZIS). The ZIS is defined as a safety area located within a land
stretch that is a buffer between some establishments and nearby popula-
tion centers.
• As for the Angangeo Project, the Environmental Natural Resources Secre-
tariat granted the Environmental Impact Authorization.
• The Santa Barbara Unit, located in the state of Chihuahaua, is in the pro-
cess of obtaining the Clean Industry certificate under the Federal Environ-
ment Protection Attorney’s Office (PROFEPA).

• Aiming at preserving fauna that,
eventually, approaches our facili-
ties, the Zinc Plant in San Luis Potosi
installed a new and modern system
called Fire Fly, which, through its
high technology, helps to prevent mi-
grating birds to approach final waste
disposal sites.
CANANEA AND LA CARIDAD
• In 2005, we started the Clean In-
dustry certification process for the
Cananea mine and La Caridad mine
Concentrator Plants, as well as for
the molybdenum plant in La Caridad.
We also registered the Action Plan
before the Federal Environmental
Protection Attorney’s Office after
having performed the corresponding
environmental audits. Additionally,
we started a Voluntary Environmental
Audit process at the Cananea Con-
centration Plant.
• We concluded Cananea’s unit internal reforestation by planting 2,500
trees. This is the company that contributes more trees in the country
to the program that the National Forestry Commission (CONAFOR) cur-
rently promotes.
• As for reforestation, we continued with the activity of linking every mu-
nicipality within the mining units’ and plants’ area of influence. During
2005, 13 municipalities of Sierra de Sonora were reforested with a total of
1,410,000 produced and planted trees. To achieve this, we were aided by
the National Defense Secretariat and the National Forestry Commission.
Currently, 1,100,000 trees are developing in the nursery and we have
scheduled to increase production to 1,550,000 trees for year 2006.
• We got the Clean Industry certification from the Natural Gas Transpor-
tation System (Gasoducto Douglas – Nacozari) facilities, within the
Environmental Audit Program of the Federal Environmental Protection
Attorney’s Office. Likewise, audits are being carried out at our facilities at
La Caridad (Hydrometalurgy Plant, Wire Rod Plant, Precious Metals Plant,
Concentrator Plant, Molybdenum Plant and Lime Plant) all of these in the
state of Sonora.
• We coordinated the Clean Community program by participating in talks
given at elementary and secondary schools and by handing out garbage
collecting containers. These activities took place in 6 cities of the state of
Sonora.

GENERAL MEXICAN DIVISION ENVIRONMENTAL ISSUES
• The Mexican division has a Qualifications System aimed at improving our
human resources performance. In 2005, we supported the Human Re-
sources Directorate by giving the Qualification Systems courses to all the
personnel of the Mexican offices, at IMMSA division managerial level em-
ployees and to employees of the Cananea and La Caridad units. Courses
which dealt with Ecologic Awareness.
• Taking into account the importance of developing an environmental
culture, together with the Information Technology Directorate, we repro-
duced the intranet page capture and design protocol on Environmental
Affairs for the Mexican SCC division.

General Information, Description of
Operations and Development
Information related to
its constitution and its
registration in the Public
Registry:
Smelter operations in Ilo Metalurgical
Complex, Peru
See: Brief historical review from the constitution of the Company on page
37.
Brief Description: Southern Copper Corporation (SCC) is a copper, molyb-
denum, zinc and silver integrated producer. All our mining, smelting and
refining facilities are located in Peru and Mexico, and we carry out explora-
tion in said countries and in Chile. Our activities make us the largest min-
ing company in Peru and Mexico. We are the largest publicly traded copper
mining company in the world based on reserves and the fifth largest cop-
per mining company in the world based on 2004 sales. Our operations in
Peru comprise mining, milling and flotation of minerals to produce copper
and molybdenum concentrates. The smelting of copper concentrates pro-
duces blister copper and blister raffinate for producing cathodes. We also
produce copper cathodes by using the SX/EW technology. We operate the
Cuajone and Toquepala mines in the heights of the Andes, approximately
984 kilometers southeast of the city of Lima, Peru. We also operate a
smelter and refinery west of the mines in Toquepala and Cuajone, in the
city of Ilo, Peru.
Our operations in Mexico are carried out by Minera Mexico S.A. de C.V., a
subsidiary we bought on April 1, 2005. Minera Mexico mainly develops ac-
tivities of mining and processing of copper, zinc, silver, gold, lead and mo-
lybdenum. Minera Mexico operates through subsidiaries that are grouped
in three separate units. Mexicana de Cobre S.A. de C.V. (together with its
subsidiaries, Mexcobre Unit), it operates an open pit mine, a copper con-
centrator, a SX/EW plant, a smelter, two refineries and a wire rod plant.
Mexicana de Cananea S.A. de C.V. (together with its subsidiaries, Cananea
Unit) operates an open pit mine located in one of the areas with more cop-
per reserves in the world, a copper concentrator and two SX/EW plants.
Industrial Minera Mexico S.A. de C.V. (Immsa) and Minerales Metalicos del
Norte S.A. (together with Immsa and its subsidiaries, Immsa Unit) operate
five underground mines producing zinc, lead, copper, silver and gold, and
a coal and coke mine and several industrial processing facilities for zinc
and copper.
We use advanced mining and processing methods, including global po-
sitioning systems (GPS). Our operations are highly integrated vertically,
which permits us to manage the whole production process, from mining to
refined copper and other products, as well as transportation and logistics,
by 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 activi-
ties 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 cop-
per, gold, silver, lead, zinc, iron and any other class of minerals and ma-
terials 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 min-
ing deposits. SCC belongs to the CIUU 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, 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. 3025091 of the Ju-
ridical Entities Registry Office of Lima and Callao (before: Entry N° 384 of
the Record N° 2447 of the Mining Registry of Natural and Juridical Entities
of the Public Mining Registry).
Actions following company incorporation:
Capital increase:
By Public Deed dated May 31, 1995, signed before the notary public of
Lima, Dr. Carlos A. Sotomayor Bernos, registered in Card 2447 of the Pub-
lic Mining Registry, the Branch capital increase was formalized. It was
made through money contribution by the Company in favor of its Peru
Branch and by the owners of labor shares, pursuant to Legislative De-
cree 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 contri-
bution made by the Labor Shares (to-
day 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 Capi-
tal.
Exchange of Labor Shares for Common
Shares:
Dated September 7, 1995, Southern
Copper Holding Company was also
incorporated pursuant to the Laws of
the State of Delaware, for the purpose
of acting as a holding company that
owner of all Southern Peru Copper Cor-
poration shares, and of performing an
exchange of the shares that were then
called Labor Shares (today Investment
Shares) issued by the branch in Peru,
and delivering to 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 In-
vestment Shares).

page 41
SOUTHERN COPPER CORPORATION
On December 31, 1995, Southern Peru
Copper Corporation changed its corpo-
rate name for Southern Peru Limited,
and Southern 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 Cor-
poration and Southern Peru Limited
was agreed. The first company ab-
sorbed 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 per-
centage in the corporate capital or in
the Patrimonial Participation Account
(investment shares), which were kept
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 Corpo-
ration, Peru Branch, or the abbreviated
name of Southern Peru and or the acro-
nym SPCC.
Change of Economic Group:
In November 1999, Grupo Mexico S. A. de C. V., a company incorporated
pursuant to the Laws of the Republic of Mexico, acquired in the United Stated
100% of ASARCO, Inc. shares, the main shareholder of Southern Peru Cop-
per Corporation at that time. In this way, SPCC became a subsidiary of Grupo
Mexico, which keeps its shareholding through American Mining Company
(AMC).
Acquisition of Minera Mexico, S.A. de C.V. (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 company incorporated pursuant to the
Laws of the Republic of Mexico. This transaction was approved by more than
90% of the issued shares of the capital of SCC. To acquire MM, SCC issued
67,207,640 shares in exchange for MM shares. Once the shares related to
the acquisition were issued, Americas Mining Corporation increased its
share in SCC from 54.3% to approximately 75.1%.
Change in the Articles of Incorporation Deed:
On March 28, 2005, following Board of Directors recommendations, SCC
shareholders approved in an extraordinary meeting the amendments to the
Certificate of Incorporation, changing the composition and obligations of
some Board committees.
Special Independent Director:
The changes to the Certificate of Incorporation 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 Nomi-
nation Committee of the Board. A special independent director may only be
removed from the Board upon a justified cause.
The number of special independent directors on tha Board at any time shall
equal (a) the total number of directors on the Board multiplied by (b) the per-
centage of Common Shares all the shareholders (that are not Grupo Mexico
and its affiliates) have, rounding up to the following whole number. Notwith-
page 40
ANNUAL REPORT
page 41
SOUTHERN COPPER CORPORATION
standing the above mentioned, the total number of persons appointed as
special independent directors (not belonging to Grupo Mexico) cannot be
less than two or more than six.
Special Nominating Committee:
To appoint persons as candidates for the election of special independent
directors and cover special independent directors vacancies, the amendment
to the Certificate of Incorporation requires the Company to appoint a Special
Nominating Committee. The Special Nominating Committee must be made up
by three SCC directors, two (2) of which are currently Mr. Luis Miguel Palomino
and Mr. Carlos Ruiz Sacristan (each one an Initial Director and, together with
their successors, the Special Designees) and any other director, who was
initially Mr. Oscar Gonzalez Rocha and is now Mr Armando Ortega Gomez, as
appointed by the Board or the Board Designee. The Board Designees will be
annually selected by the Board. The Special Designees will be annually se-
lected by the member of the Board who are special independent directors or
Initial Directors. Only the special independent directors can cover vacancies
in the Special Nominating Committee. Any member of the Special Nominating
Committee can be removed at any time by the Board with a justified cause.
The unanimous vote of all the members in the Special Committee will be nec-
essary to adopt any agreement or to take any action.
Notwithstanding the above mentioned, the Special Nominating Committe’s
power to name special independent Directors Designees is subjected to the
shareholders’ right to appoint directors pursuant to the by-laws.
The amendment provisions referring to the special independent directors
may be modified only with the favorable vote of the majority of the Common
Shares owners (calculated without applying qualified majority voting right)
that are not Grupo Mexico and its affiliates.
Transactions with affiliates:
The amendments to the Certificate also prohibit the Company to undertake
important transactions with affiliates, except if the transaction has been
reviewed 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

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 Cop-
per Corporation to Southern Copper
Corporation or SCC. The change was
adopted because the new corporate
the
name
reflects more precisely
Company’s operations outside
the
Republic of Peru after its acquisition
of Minera Mexico and SCC’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 Certificate of Incor-

poration to remove other provisions
in our Certificate 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 follow-
ing agreement of the majority Board
members, provided that the number
of directors will not be less than six or
more than fifteen.
The Certificate amendment was sub-
mitted 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 corporate
name of the parent should comprise the
corresponding change of name of the
ancillary organizations linked to it, as
is the case of the Peru Branch through
which the Corporation develops its min-
ing activities in Peru.
After consulting with Peruvian lawyers,
the Board of Directors, taking into con-
sideration the net worth and assets
importance of the Branch, the need to
continue acknowledging the position of the Peruvian Branch with its local and
international copper clients, the need to preserve its prestige and its position
and good name in the copper market, and the need to prevent any possible cli-
ent 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 of 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 By-laws:
Dated January 26, 2006, the Board approved amendment to Southern Cop-
per Corporation’s by-laws aiming at removing the provisions related to Class
A Common Shares, among other changes. These changes will be submitted
to approval by the shareholders at the annual shareholder meeting to take
place in April 2006.
SCC is, indirectly, part of Grupo Mexico S.A. de C.V. who owns 100% of

Relationship between the Issuer and the Government
On November 20, 1996, SCC and the Peruvian Government (Ministry of En-
ergy and Mines) signed a contract that will remain effective until the year
2010 which guarantees 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 at the Solvent Extraction (SX) operation in Cua-
jone. Also, on April 18th, 1995, SCC and the Peruvian Government (CONITE)
signed a contract that guarantees the availability of foreign currencies, free
remittance of dividends outside Peru, among other guarantees related to the
acid plant of the Ilo Smelter.
SCC obtains revenues 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 this refund, SCC is entitled to credit the amount of the
IGV against its Peruvian tax obligations or to receive a refund.

Mining Safety:
Peruvian Operations
In 2005, the open pit operations at the mines of Toquepala and Cuajone,
as well as operations performed at the Ilo metallurgical complex which in-
cludes our Smelter and refinery, were awarded a prize by the Mining Safety
Institute - Instituto de Seguridad Minera (ISEM), in recognition for our
excellent statistical results in obtaining a reduction of personal accidents
and consequently in the Indexes of Frequency Safety, Severity and Acci-
dents.
Mexican Operations
The Mexican Mining Chamber (CAMIMEX), which recognizes those en-
terprises with a low accident level, in 2005, granted our metallurgical
complex of La Caridad the highest award for safety in the mining industry,
which is the Silver Helmet. Likewise, as during the past three years, the
concentrator mine of La Caridad obtained the Silver Helmet, this prize was
awarded in definitive manner. The mining units Santa Eulalia and Cananea
were awarded a diploma for safety for reducing accidents to at least 25%.

million outstanding) credit facilities, respectively, and the balance will be
used for general corporate purposes. SCC filed a Registration Statement
on Form S-4 with respect to these Notes on October 28, 2005. On Janu-
ary 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 ag-
gregate 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, limita-
tions 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, 2005, we are in compliance with these cov-
enants.
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 Pe-
ruvian bond program. On July 28, 2005, a portion of the proceeds from the
July 27, 2005 financing, noted above, were used to repay this facility.
In 1998, Minera México 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 2005, the Company repurchased $143.0 mil-
lion of the Series A bonds. 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, 2005,
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 4.67% at December 31, 2005).
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 México’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, 2005, 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 princi-
pal properties and was guaranteed by its principal subsidiaries. In 2005,
the Company prepaid the total amount of this financing, using in part pro-
ceeds from the July 27, 2005 Note issuance.
While we recently prepaid all amounts outstanding under our Peruvian
bond program, we are authorized by Peru’s Comisión Nacional Supervisora
de Empresas y Valores (CONASEV) to issue additional bonds.
We expect that we will meet our cash requirements for 2006 and beyond
from internally generated funds, cash on hand and from additional exter-
nal financing if required.

Messrs. German Larrea Mota-Velasco, Chairman of the Board ofthe 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 75.1% of
the stock of the Company. The Company has taken advantage of the excep-
tions 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 financial-
ly literate in accordance with the qualifications of the NYSE and the Securi-
ties and Exchange Commission (SEC), as such qualifications are interpreted
by the Company’s 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
