NOTE REGARDING FORWARD-LOOKING STATEMENTS
This offering memorandum contains forward-looking statements. We may from time to time make
forward-looking statements in our annual report, in prospectuses, press releases and other written materials and in
oral statements made by our officers, directors or employees to analysts, institutional investors, representatives of
the media and others. Examples of these forward-looking statements include:
· projections of revenues, net income (loss), capital expenditures, dividends, capital structure or other financial
items or ratios;
· statements of our plans, objectives or goals, including those relating to anticipated trends, competition,
regulation and rates;
· statements about our future economic performance or that of Chile or other countries in which we have
investments; and
· statements of assumptions underlying these statements.
Words such as "believe," "could," "may," "will," "anticipate," "plan," "expect," "intend," "target,"
"estimate," "project," "potential," "predict," "forecast," "guideline," "should" and similar expressions are intended
to identify forward-looking statements, but are not the exclusive means of identifying these statements.
Forward-looking statements involve inherent risks and uncertainties. We caution you that a number of
important factors could cause actual results to differ materially from the plans, objectives, expectations, estimates
and intentions expressed in these forward-looking statements. These factors, some of which are discussed under
"Risk Factors," include economic and political conditions and government policies in Chile or elsewhere, inflation
rates, exchange rates, regulatory developments and changes in Chilean law, customer demand, competition,
unanticipated mining and production problems, commodity prices, relations with employees and contractors,
variances in ore grade, adverse weather conditions and natural disasters. We caution you that the foregoing list of
factors is not exclusive and that other risks and uncertainties may cause actual results to differ materially from those
in forward-looking statements.
You are cautioned not to place undue reliance on these forward-looking statements which reflect our views
only as of the date they are made, and we do not undertake any obligation to update them or publicly to release the
result of any revisions to these forward-looking statements in light of new information or future developments after
the date of this offering memorandum.

ENFORCEABILITY OF CIVIL LIABILITIES
Corporación Nacional del Cobre de Chile (together with its consolidated subsidiaries, "CODELCO" or the
"Company") is a state-owned enterprise organized under the laws of Chile. All of its directors and executive
officers and certain experts named in this offering memorandum reside outside the United States (principally in
Chile) and all or a substantial portion of the assets of CODELCO and of such persons are located outside the United
States. As a result, it may not be possible for investors to effect service of process within the United States on, or
bring actions or enforce foreign judgments against, CODELCO or such persons in U.S. courts. In addition,
CODELCO has been advised by its Chilean counsel, Carey y Cía. Ltda., that no treaty exists between the United
States and Chile for the reciprocal enforcement of foreign judgments. There is also doubt as to the enforceability in
Chilean courts of judgments of U.S. courts obtained in actions predicated upon the civil liability provisions of the
U.S. federal securities laws. Chilean courts, however, have enforced judgments rendered in the United States by
virtue of the legal principles of reciprocity and comity, subject to the review in Chile of the U.S. judgment in order
to ascertain whether certain basic principles of due process and public policy have been respected, without
reviewing the merits of the subject matter of the case. Lastly, CODELCO has been advised by Carey y Cía. Ltda.
that there is doubt as to the enforceability in original actions in Chilean courts of liabilities predicated solely upon
U.S. federal securities laws.
The notes, the Fiscal and Paying Agency Agreement and the Purchase Agreement will provide that
CODELCO will appoint the Chilean consul in New York City as its agent upon whom process may be served in any
action arising out of or based upon, respectively, the notes, the Fiscal and Paying Agency Agreement, the Purchase
Agreement or the transactions contemplated thereby, which may be instituted in any federal or state court having
"subject matter" jurisdiction. See "Description of Notes."
Pursuant to the Chilean Mining Code, mining concessions as well as certain raw materials and other
property or assets permanently dedicated to the exploration or extraction of minerals cannot be subject to an order of
attachment, except with respect to mortgages or in the case that the debtor consents to the attachment in the same
enforcement proceeding. In addition, pursuant to the Chilean Constitution, mining concessions corresponding to
mining deposits exploited by CODELCO upon its creation in 1976 cannot be subject to attachment nor to any act of
disposition by CODELCO. As a result, the rights of holders to attach property of CODELCO in the event of a
default under the notes would be limited by such provisions. See "Regulatory Framework--Mining Regulations."

v





PRESENTATION OF FINANCIAL AND STATISTICAL INFORMATION
In this offering memorandum, references to "U.S.$," "$," "U.S. dollars" and "dollars" are to United States
dollars, references to "cents" are to United States cents (U.S.$0.01), references to "pesos" or "Ch$" are to Chilean
pesos and references to "UF" are to "Unidades de Fomento." The UF is an inflation-indexed Chilean monetary unit
which is linked to, and which is adjusted daily to reflect changes in, the Chilean consumer price index during the
preceding 30 days.
Pursuant to Oficio Circular 368 of October 2006, as amended, of the Superintendencia de Valores y
Seguros ("SVS"), or the Chilean Superintendency of Securities and Insurance, beginning in 2010, all companies
with publicly traded securities in Chile are required to prepare and report consolidated financial statements in
accordance with International Financial Reporting Standards ("IFRS") as adopted by the International Accounting
Standards Board (IASB). As of January 1, 2010, CODELCO no longer prepares financial statements in accordance
with generally accepted accounting principles in Chile ("Chilean GAAP"). CODELCO's first results reported under
IFRS were the unaudited interim financial statements as of and for the three-month period ended March 31, 2010.
Financial results for the fiscal year ended December 31, 2009 have been reconstructed according to IFRS in order to
make them comparable to our 2010 and 2011 financial statements.
The audited consolidated statements of financial position as of December 31, 2009, 2010 and 2011 and the
opening consolidated statement of financial position as of January 1, 2009 and the consolidated statements of
comprehensive income for the years ended December 31, 2009, 2010 and 2011 included herein (the "Year-end
Consolidated Financial Statements"), are presented in accordance with IFRS. The consolidated financial statements
for the year ended December 31, 2011 are referred to as the "2011 Year-end Consolidated Financial Statements."
The unaudited interim consolidated statements of financial position as of March 31, 2012 and the unaudited
consolidated statements of comprehensive income, changes in equity and cash flows for the three month periods
ended March 31, 2011 and 2012 (the "Unaudited Interim Consolidated Financial Statements") included in this
offering memorandum are presented in accordance with IFRS. The Unaudited Interim Consolidated Financial
Statements and the Year-end Consolidated Financial Statements are referred to together as the "Consolidated
Financial Statements."
Unless otherwise indicated, the Consolidated Financial Statements and other financial information
concerning CODELCO included herein are presented in U.S. dollars in conformity with Decree Law 1.350 of 1976,
as amended by Law 20.392 published in the Official Gazette on November 14, 2009, and for periods after January,
1, 2009, in accordance with IFRS. Decree Law 1.350 is the Chilean law pursuant to which CODELCO was created
and which provides for its governance.
Because the notes offered hereby have not been and will not be registered with the SEC, the Consolidated
Financial Statements do not and are not required to comply with the applicable requirements of the Securities Act,
and the related rules and regulations adopted by the SEC, which would apply if the notes offered hereby were being
registered with the SEC.
The U.S. dollar is the currency used in the primary economic environment in which CODELCO operates.
Nevertheless, as an international company operating primarily in Chile as well as in several other Latin American
countries, a portion of CODELCO's business is transacted in Chilean pesos and other non-dollar currencies.
Adjusted EBITDA data is included in this offering memorandum because such data is used by certain
investors to measure a company's ability to service debt and fund capital expenditures, and it is included herein for
convenience only. CODELCO calculates Adjusted EBITDA by adding interest expense, taxes (including income
and export taxes), depreciation and amortization to net income, in accordance with IFRS. Adjusted EBITDA is not
a measure of financial performance or liquidity under IFRS and should not be considered in isolation or as a
substitute for net income as a measure of operating performance, or as an alternative to cash flows as a measure of
liquidity. Additionally, the Company's calculation of Adjusted EBITDA may be different than the calculation used
by other companies, and therefore comparability may be affected.

vi





Under IFRS, gross profit is calculated before provision for the 10% special export tax payable by
CODELCO under Law 13.196, as well as the 5.7% mining tax that became effective in January 2006 pursuant to a
modification of Chilean Income Tax Law 824 (Decreto Ley 824). See also "Risk Factors--Risks Relating to
CODELCO's Relationship with the Chilean Government--CODELCO is subject to special taxes and distributions"
for information related to the mining tax rate effective in 2012.
Certain figures included in this offering memorandum and in the Consolidated Financial Statements have
been rounded for ease of presentation. Percentage figures included in this offering memorandum have in some cases
been calculated on the basis of such figures prior to rounding. For this reason, certain percentage amounts in this
offering memorandum may vary from those obtained by performing the same calculations using the figures in the
Consolidated Financial Statements. Certain other amounts that appear in this offering memorandum may not sum
due to rounding.
The Observed Exchange Rate (as defined herein under "Exchange Rates") reported by the Central Bank of
Chile as of December 30, 2011 was Ch$521.46 = U.S.$1.00, as of March 30, 2012 was Ch$489.76 = U.S.$1.00 and
as of July 9, 2012 was Ch$499.26 = U.S.$1.00. The Federal Reserve Bank of New York does not report a noon
buying rate for Chilean pesos. See "Exchange Rates."
All tonnage information in this offering memorandum is expressed in metric tons and all references to
ounces are to troy ounces, in each case, unless otherwise specified. Tonnage information in this offering
memorandum does not include CODELCO's share of the El Abra deposit, which is mined by Sociedad Contractual
Minera El Abra, owned 49% by CODELCO and 51% by Cyprus El Abra Corporation (a subsidiary of Freeport
McMoRan Copper & Gold, Inc. ("Freeport McMoRan")), unless otherwise specified. Certain terms relating to the
copper mining business are defined in "Glossary of Certain Mining Terms."
Market information regarding CODELCO's share of copper production, reserves and relative cost position
has been derived by CODELCO from third-party sources, including reports of Brook Hunt & Associates, and from
CODELCO's own industry research. Brook Hunt & Associates publishes periodic reports containing global copper
production data and cost analysis by mine site. While CODELCO believes that its estimates are reliable, such
estimates have not been confirmed by independent sources. The Consolidated Financial Statements do not reflect
the value of CODELCO's mining concessions or its resources and reserves.
As used in this offering memorandum, "cash cost" is calculated in accordance with the methodology
specified by Brook Hunt & Associates for determination of C1 cost (cash cost) and includes all direct cash costs of
mining, including costs associated with extraction, leaching, smelting and further processing of copper ores into
refined metal, as well as labor, transportation and physical plant costs associated with those processes, net of income
from sales of by-products. Cash cost figures are given as nominal dollar amounts, usually expressed as cents per
pound, and exclude provisions, amortization, depreciation and central office costs. Cash cost is presented because it
is a widely used measure of costs, although it is not an IFRS or U.S. GAAP-based measure of cost. The Company
believes that cash cost, while providing useful information, should not be considered in isolation or as a substitute
for costs of sales, costs of selling and administrative expenses, or as an indicator of costs.
As used in this offering memorandum, "Chuquicamata," "Radomiro Tomic," "El Teniente," "Andina,"
"Salvador" and "Mina Ministro Hales" refer to the divisions of CODELCO, not the mines having those names,
unless otherwise required by context.
As used in this offering memorandum, the term "billion" means one thousand million (1,000,000,000).

vii





SUMMARY
This summary must be read as an introduction to this offering memorandum and any decision to invest in
the notes should be based on a consideration of the offering memorandum as a whole, including the documents
incorporated by reference.
The following summary is qualified in its entirety by the more detailed information and financial statements
appearing elsewhere in this offering memorandum. Unless otherwise indicated, financial information with respect
to CODELCO provided in this offering memorandum has been presented in U.S. dollars and prepared in
accordance with IFRS.
CODELCO is the world's largest copper producer and the largest company in Chile in terms of sales
(U.S.$17.51 billion in 2011). As of December 31, 2011, CODELCO's total assets and equity amounted to
U.S.$20.83 billion and U.S.$6.06 billion, respectively, without including the value of CODELCO's mining
concessions and ore deposits (as of March 31, 2012, such amounts were U.S.$21.30 billion and U.S.$6.53 billion,
respectively).
CODELCO engages primarily in the exploration, development and extraction of ores bearing copper and
by-products, the processing of ore into refined copper and the international sale of refined copper and by-products.
CODELCO is 100% owned by the Republic of Chile and controls approximately 9% of the world's proven and
probable copper reserves, as such term is defined by the U.S. Geological Survey.
In 2011, CODELCO had an estimated 11% share of total world copper production, with production of
approximately 1.80 million metric tons (including CODELCO's share of the El Abra deposit, which is mined by
Sociedad Contractual Minera El Abra, owned 49% by CODELCO and 51% by Cyprus El Abra Corporation, a
subsidiary of Freeport McMoRan) and an estimated 9% share of the world's molybdenum production, with
production of approximately 23,098 metric tons.
CODELCO's main commercial product is Grade A cathode copper. In 2011, CODELCO derived 90% of
its total sales from copper and 10% of its total sales from by-products of its copper production. For the three-month
period ended March 31, 2012, CODELCO derived 91% of its total sales from copper and 9% of its total sales from
by-products of its copper production.
CODELCO's sales of copper in 2011 were geographically diversified, with approximately 58% of sales
made to Asia, including 36% to China, 21% to Europe, 21% to North America and South America, and the
remainder to Oceania. CODELCO's top ten customers purchased approximately 31% of its total copper sales
volume in 2011.
CODELCO's copper operations are divided into seven divisions and, separately, CODELCO operates the
Gabriela Mistral Mine, which is referred to as Gabriela Mistral. In December 2010, CODELCO divided the former
CODELCO Norte Division into the Chuquicamata and Radomiro Tomic Divisions.
· The Chuquicamata Division operates the Chuquicamata mine, one of the largest copper producing mines in the
world, which began its operations in 1915 and currently includes smelting and refining capacities. In 2011, this
division produced 443,381 metric tons of copper cathodes, or 24.7% of CODELCO's total copper output
(including CODELCO's share of the El Abra deposit), with a cash cost of 110.8 cents per pound and a total
cash cost of U.S.$1,078 million.
· The Radomiro Tomic Division operates the Radomiro Tomic mine, which began its first full year of production
in 1998 and is the world's largest producer of copper using the SX-EW technology. In 2011, this division
produced 470,096 metric tons of copper cathodes, or 26.2% of CODELCO's total copper output (including
CODELCO's share of the El Abra deposit), with a cash cost of 100.3 cents per pound and a total cash cost of
U.S.$1,028 million.

1





· The El Teniente Division is the operator of El Teniente mine, which is the world's largest underground copper
mine and has been in operation for more than 100 years. The El Teniente Division includes the Caletones
smelter. In 2011, this division produced 400,294 metric tons of copper, or 22.3% of CODELCO's total copper
output (including CODELCO's share of the El Abra deposit), with a cash cost of 92.4 cents per pound and a
total cash cost of U.S.$810 million.
· The Andina Division operates the Andina and Sur-Sur mines with production split among open-pit and
underground mines. It does not have independent smelting capacity. Andina has been in operation since 1970
and produced 234,348 metric tons of copper in 2011, or 13.0% of CODELCO's total copper output (including
CODELCO's share of the El Abra deposit), with a cash cost of 127.9 cents per pound and a total cash cost of
U.S.$639 million.
· The Salvador Division includes the Salvador mine and concentrator and the smelter/refinery complex at
Potrerillos, which has a capacity to treat 671,000 metric tons of concentrate. Salvador produced 69,044 metric
tons of copper cathodes in 2011 from its own mine production, or 3.8% of CODELCO's total copper output
(not including CODELCO's share of the El Abra deposit), with a cash cost of 175.2 cents per pound and a total
cash cost of U.S.$267 million. CODELCO's Board of Directors has decided to phase out mining operations at
the Salvador mine by 2016, or by 2021 if warranted by market and operational conditions. The Potrerillos
smelter and refinery will continue to operate upon any cessation of the mining operations at Salvador.
· The Ventanas Division was created in connection with the acquisition of the Ventanas smelter/refinery complex
from the Republic of Chile's state-owned mining company Empresa Nacional de Minería ("ENAMI") in May
2005. The Ventanas smelter has a capacity to treat 400,000 metric tons of concentrate. Ventanas refined
401,509 metric tons of copper in 2011. Pursuant to the terms of the acquisition, CODELCO is required to
provide on market terms the necessary smelting and refining capacity for the treatment of copper concentrate
delivered by the small- and medium-sized mining industry that ENAMI serves.
· The Mina Ministro Hales Division was created in September 2010 for the operation of the Mina Ministro Hales
ore body, which is expected to begin operations starting at the end of 2013 and expected to produce an average
of 170,000 tons of copper per year and 287 tons of silver per year when in full operation in 2014.
CODELCO also operates Gabriela Mistral, which uses SX-EW technology. Gabriela Mistral produced its first
copper cathodes in May 2008 after a 26-month construction period at a cost of U.S.$1.03 billion. In 2011, this mine
produced 118,078 metric tons of copper, or 6.6% of CODELCO's total copper output (including CODELCO's share
of the El Abra deposit) with a cash cost of 163.5 cents per pound and a total cash cost of U.S.$432 million. The ore
body is located in Chile's Second Region and contains proven and probable reserves of 542 million metric tons of
oxidized mineral with a grade of 0.4% of total copper.

Competitive Strengths
CODELCO believes it has certain distinguishing competitive strengths:
· Copper Reserves. CODELCO controls approximately 9% of the world's proven and probable copper reserves.
In 2011, CODELCO's proven and probable reserves represented at least 34 years of future production at current
levels. According to the U.S. Geological Survey, CODELCO's proven and probable reserves increased from
57.1 million tons in 2010 to 60.5 million tons in 2011.
· Market Presence. CODELCO is the largest copper producer in the world, with an estimated 11% share of the
total world copper production, with 1.80 million metric tons (including CODELCO's share of the El Abra
deposit) of production in 2011. CODELCO is also one of the largest producers of molybdenum in the world,
with an estimated 9% share of total world molybdenum production, with 23,098 metric tons in 2011.
