We may redeem the notes at our option, in whole or in part, at any time and from time to time prior to the date that is
six months prior to the maturity date, at a redemption price equal to the greater of 100% of the outstanding principal
amount of the notes to be redeemed and a redemption price based on a "make-whole" premium, plus accrued and
unpaid interest to the date of redemption. In addition, we may redeem the notes at our option, in whole or in part, at
any time and from time to time, beginning on the date that is six months prior to the maturity date, at a redemption

interest to the date of redemption. Upon the occurrence of specified events relating to Chilean tax law, we may
redeem the notes in whole, but not in part, at 100% of their principal amount, plus accrued and unpaid interest to the
date of redemption. See "Description of Notes--Tax Redemption" and "--Optional Redemption".
The notes constitute direct, general, unconditional, unsecured and unsubordinated obligations of Corporación

themselves and equally with all other unsubordinated and unsecured obligations of CODELCO, other than certain

construed so as to require CODELCO to make payments under the notes ratably with payments being made under
any other obligations. See "Description of Notes--Ranking."
Application has been made to list the notes on the Official List of the Luxembourg Stock Exchange and for trading
on the Euro MTF market of the Luxembourg Stock Exchange. This Offering Memorandum constitutes a

This offering memorandum is for distribution only to persons who (i) have professional experience in
matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000
(Financial Promotion) Order 2005 (the "Order"), (ii) are persons falling within Article 49(2)(a) to (d) ("high net
worth companies, unincorporated associations etc.") of the Order, (iii) are outside the United Kingdom (the "UK"),
or (iv) are persons to whom an invitation or inducement to engage in investment activity (within the meaning of
section 21 of the Financial Services and Markets Act 2000) in connection with the issue or sale of any securities
may otherwise lawfully be communicated (all such persons together being referred to as "relevant persons"). This
offering memorandum is directed only at relevant persons and must not be acted on or relied on by persons who are
not relevant persons. Any investment or investment activity to which this offering memorandum relates is available
only to and will be engaged in only with relevant persons. Any person who is not a relevant person should not act or

The notes are not intended to be offered, sold, or otherwise made available to and should not be offered,
sold or otherwise made available to any retail investor in the European Economic Area ("EEA") or in the UK. For
these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of
Article 4(1) of Directive 2014/65/EU (as amended, "MiFID II"); or (ii) a customer within the meaning of Directive
(EU) 2016/97 (as amended, the "Insurance Distribution Directive"), where the customer would not qualify as a
professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document
required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the notes
or otherwise making them available to retail investors in the EEA or in the UK, has been prepared and therefore the
offering or selling of the notes or otherwise making them available to any retail investor in the EEA or in the UK
may be unlawful under the PRIIPs Regulation.

investing in the notes.

NOTE REGARDING FORWARD-LOOKING STATEMENTS
This offering memorandum contains forward-looking statements. We may from time to time make
forward-looking statements in (i) our annual report; (ii) prospectuses, press releases and other written materials; or
(iii) 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, profit (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," "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, natural disasters and the duration and severity of the recent
outbreak of coronavirus ("COVID-19") and its potential impact on our business. 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.


iv






ENFORCEABILITY OF CIVIL LIABILITIES
CODELCO 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 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 indenture 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 indenture, 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, in the case that the debtor consents to the attachment in the same
enforcement proceeding or when the debtor is a stock corporation. In addition, pursuant to the Chilean constitution
(the "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."

PRESENTATION OF FINANCIAL AND STATISTICAL INFORMATION
In this offering memorandum, references to "U.S.$," "$," "U.S. dollars" and "dollars" are to United States
dollars and 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." References to "AUD" are to Australian
dollars. References to "HKD" are to Hong Kong dollars. The UF is an inflation-indexed Chilean monetary unit that
is linked to, and adjusted daily to reflect changes in, the Chilean consumer price index during the preceding 30 days.
References to "euro" or "" are to the legal currency of the European Economic and Monetary Union.
Pursuant to Circular N° 368 (Oficio Circular N° 368) of October 2006, as amended, of the Comisión para
el Mercado Financiero (the Chilean securities authority, or "CMF"), since 2010, all companies with publicly traded
securities in Chile have been required to prepare and report consolidated financial statements in accordance with
International Financial Reporting Standards ("IFRS") issued by the International Accounting Standards Board
("IASB").
The audited consolidated financial statements as of and for the years ended December 31, 2017 and 2018
and the audited consolidated financial statements as of and for the years ended December 31, 2018 and 2019
included herein are referred to as the "2017-2018 Consolidated Financial Statements" and the "2018-2019
Consolidated Financial Statements," respectively. The 2017-2018 Consolidated Financial Statements and the
2018-2019 Consolidated Financial Statements (together, the "Audited Annual Consolidated Financial Statements")
are presented in accordance with IFRS issued by the IASB.
The unaudited interim consolidated financial statements as of September 30, 2020 and for the nine-month
periods ended September 30, 2019 and 2020 included herein (the "Unaudited Interim Consolidated Financial
Statements") are presented in accordance with IAS 34 "Interim Financial Reporting." The Unaudited Interim
Consolidated Financial Statements and the Audited Annual Consolidated Financial Statements are referred to
together as the "Consolidated Financial Statements."

The accounting policies adopted in the preparation of the Unaudited Interim Consolidated Financial
Statements are consistent with those applied in the preparation of the 2018-2019 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 Diario Oficial de la República de Chile (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, this offering
memorandum does not and is 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, several European countries and China, a portion of CODELCO's business is transacted in Chilean pesos
and other non-dollar currencies.
The body of generally accepted accounting principles is commonly referred to as "GAAP." A non-GAAP
financial measure is generally defined by the SEC as one that purports to measure historical or future financial
performance, financial position or cash flows but: (i) excludes amounts, or is subject to adjustments that have the
effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in
accordance with GAAP in the issuer's statement of income, balance sheet or statement of cash flows (or equivalent
statements); or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are
excluded from the most directly comparable measure so calculated and presented.

vi


#93837554v8




In this offering memorandum, CODELCO discloses several non-GAAP financial measures, including
"Adjusted EBIT," "Adjusted EBITDA," "cash cost," "total costs and expenses" and "financial debt." Adjusted EBIT
is calculated by adding finance cost, impairment charges and income tax expense to profit (loss) for the period.
Adjusted EBITDA is calculated by adding finance cost, income tax expense, depreciation and amortization of assets
plus export taxes and impairment charges to profit (loss) for the period. Impairments include charges and reversals
related to charges of investment projects, research projects and investment in associates and joint ventures and
exclude impairment charges related to definitely-lived tangible assets which show indicators of impairment under
International Accounting Standard N° 36. Cash cost is calculated in accordance with the methodology specified by
Brook Hunt & Associates for the 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, electricity, diesel, finance costs, third-party services, other costs, transportation and physical
plant costs associated with those processes, net of income from sales of byproducts. Cash cost is presented as a
nominal dollar amount, usually expressed as cents per pound, and excludes provisions, amortization, depreciation
and central office costs. Financial debt is calculated as loans from financial institutions plus bonds issued. Total debt
to capitalization includes total financial debt divided by total financial debt plus total equity.
Adjusted EBIT and Adjusted EBITDA data are included in this offering memorandum because such data
are used by investors to assess: (i) the operating trends and financial performance of the Company and (ii) the ability
of the Company to (a) service its existing debt, (b) incur new debt and (c) fund its capital expenditures.
CODELCO believes that Adjusted EBIT and Adjusted EBITDA, while providing useful information,
should not be considered in isolation or as a substitute for profit for the period as an indicator of operating
performance or as an alternative to cash flow as a measure of liquidity. Adjusted EBIT and Adjusted EBITDA are
not measures of financial performance in accordance with IFRS. Additionally, CODELCO's calculation of Adjusted
EBIT and Adjusted EBITDA may differ from the calculation used by other companies and, therefore, comparability
may be affected.
Cash cost is disclosed in this offering memorandum because it is a widely used measure of costs in the
mining industry. CODELCO believes that cash cost, while providing useful information, should not be considered in
isolation or as a substitute for cost of sales, cost of selling and administrative expenses or as an indicator of costs.
Cash cost is not a measure of financial performance in accordance with IFRS.
CODELCO also presents certain ratios and margins that are derived using Adjusted EBITDA, including the
ratio of debt to Adjusted EBITDA, the Adjusted EBITDA coverage ratio and earnings to fixed charges (adjusted).
CODELCO believes that these ratios are widely used by investors to measure our performance. In the section titled
"Summary Consolidated Financial Data," CODELCO provides a reconciliation of Adjusted EBIT and Adjusted
EBITDA to profit, along with the ratio of debt to Adjusted EBITDA, Adjusted EBITDA coverage ratios and ratio of
earnings to fixed charges (adjusted), for the relevant periods.
Under the accounting policies adopted by CODELCO, gross profit is calculated before the provision for a
10% special export tax. Under Law N° 13,196 (the "Copper Reserve Law"), CODELCO is required to pay a special
export tax on the sales revenues that CODELCO derives from the export of copper sourced and related byproducts
produced by CODELCO. In addition, CODELCO is subject to a mining tax at progressive rates of between 5% and
14% in accordance with Law N° 20,026. These taxes are included in "other expenses" by function. See "Risk
Factors--Risks Relating to CODELCO's Relationship with the Government of Chile--CODELCO is subject to
special taxes" for additional information on these special taxes, including the mining tax rate effective for 2017,
2018 and 2019.
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 (i) as of January 2, 2018 was Ch$614.75 = U.S.$1.00; (ii) as of January 2, 2019 was Ch$694.77 = U.S.$1.00;
(iii) as of September 30, 2019 was Ch$725.68 = U.S.$1.00; (iv) as of January 2, 2020 was Ch$748.74 = U.S.$1.00
and (v) as of September 30, 2020 was Ch$784.46 = U.S.$1.00. The Federal Reserve Bank of New York does not
report a noon buying rate for Chilean pesos. See "Exchange Rates."
In this offering memorandum, all tonnage information is expressed in metric tons and all references to
ounces are to troy ounces, in each case, unless otherwise specified. Except where otherwise noted, tonnage
information in this offering memorandum does not include: (i) CODELCO's 49% direct share of the El Abra
deposit, which is mined by Sociedad Contractual Minera El Abra and 51% owned by Cyprus El Abra Corporation, a
subsidiary of Freeport-McMoRan Inc., or (ii) CODELCO's 20% share of Anglo American Sur S.A. ("Anglo
American Sur"), unless otherwise specified. See "Business and Properties--Copper Production--Associations, Joint
Ventures and Partnerships--SCM El Abra" and "--Anglo American Sur" for a description of these interests.
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 from 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
necessarily reflect the value of CODELCO's mining concessions or its resources and reserves. Fair value of mining
properties acquired through business combinations is reflected in the Consolidated Financial Statements when
acquired.

"El Teniente," "Andina," "Salvador," "Mina Ministro Hales" and "Ventanas" refer to divisions of CODELCO, not
the mines having those names, unless otherwise required by context.
