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"). IFRS differs in significant respects from
Chilean GAAP. See "Annex A--Significant Differences Between Chilean GAAP and IFRS" contained elsewhere
in this offering memorandum for a description of the principal differences between Chilean GAAP and IFRS as they
relate to CODELCO. 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.
The audited consolidated statements of financial position as of December 31, 2009 and 2010 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 and 2010 included herein (the "Year-end
Consolidated Financial Statements"), are presented in accordance with IFRS. We have also included audited
consolidated balance sheets of CODELCO as of December 31, 2008 and 2009 and the consolidated statement of
income for each of the years ended December 31, 2008 and 2009, presented in conformity with Chilean GAAP.
The unaudited interim consolidated statements of financial position as of June 30, 2011 and the unaudited
consolidated statements of income, comprehensive income, changes in equity and cash flows for the three and six-
month periods ended June 30, 2011 and 2010 (the "Unaudited Interim Consolidated Financial Statements") included
in this offering memorandum are presented in accordance with IFRS. The Unaudited Interim Consolidated
Financial Statements, the Year-end Consolidated Financial Statements and the consolidated financial statements
presented for each of the years ended December 31, 2008 and 2009 in accordance with Chilean GAAP in this
offering memorandum are sometimes 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 each case determined in accordance with Chilean
GAAP or IFRS, as the case may be. Adjusted EBITDA is not a measure of financial performance or liquidity under
Chilean GAAP or IFRS and should not be considered in isolation or as a substitute for net income as a measure of

vi

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.
Under IFRS and Chilean GAAP, gross profit is calculated before provision for the 10% special export tax
payable by CODELCO under Law 13.196, as well as the 5% 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 31, 2010 was Ch$468.37 = U.S.$1.00, as of June 30, 2011 was Ch$471.13 = U.S.$1.00 and as
of October 27, 2011 was Ch$501.12 = 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, U.S. or Chilean 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).

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 for periods prior to January 1, 2009 has been prepared in
accordance with Chilean GAAP, and financial information for periods subsequent to January 1, 2009 has been
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.$16.07 billion in 2010). As of December 31, 2010, CODELCO's total assets and equity amounted to
U.S.$20.28 billion and U.S.$4.53 billion, respectively, without including the value of CODELCO's mining
concessions and ore deposits (as of June 30, 2011, such amounts were U.S.$20.01 billion and U.S.$5.63 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 2010, CODELCO had an estimated 11% share of total world copper production, with production of
approximately 1.76 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 21,677 metric tons.
CODELCO's main commercial product is Grade A cathode copper. In 2010, CODELCO derived 92% of
its total sales from copper and 8% of its total sales from by-products of its copper production (and for the six-month
period ended June 30, 2011, 90% and 10%, respectively).
CODELCO's sales of copper in 2010 were geographically diversified, with approximately 59% of sales
made to Asia, including 43% to China, 20% to Europe, 20% to North America and South America, and the
remainder to Oceania. CODELCO's top ten customers purchased approximately 26% of its total copper sales
volume in 2010.
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
2010, this division produced 528,377 metric tons of copper cathodes, or 31.3% of CODELCO's total copper
output (including CODELCO's share of the El Abra deposit), with a cash cost of 106.6 cents per pound.
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 2010, this
division produced 375,344 metric tons of copper cathodes, or 22.2% of CODELCO's total copper output
(including CODELCO's share of the El Abra deposit), with a cash cost of 96.7 cents per pound.
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 2010, this division produced 403,616 metric tons of copper, or 23.9% of
