                                 PROXY STATEMENT

      This proxy statement is furnished as part of the solicitation by the Board
of Directors of Southern Peru Copper Corporation, 180 Maiden Lane, New York,
N.Y. 10038 and Avenida Caminos del Inca No. 171, Chacarilla del Estanque,
Santiago de Surco, Lima 33, Peru, of the proxies of all holders of common stock,
par value $0.01 per share (the "Common Stock") entitled to vote at the annual
meeting to be held on May 9, 2000 and at any adjournment thereof. This proxy
statement is not soliciting proxies from holders of Class A Common Stock whose
proxies are being solicited separately. This proxy statement and the enclosed
form of proxy are being mailed commencing on or about March 30, 2000, to holders
of Common Stock of record on March 10, 2000. Additional copies will be available
at the Company's offices in Lima and other locations in Peru.

      Southern Peru Copper Corporation was reorganized into a holding company
structure effective January 2, 1996, upon completion of a public offer to
exchange newly-issued Common Stock for outstanding labor shares (now referred to
as "investment shares") of the Company's Peruvian Branch. Effective December 31,
1998, the Company's predecessor and wholly-owned operating subsidiary, Southern
Peru Limited, was merged into the Company. Throughout this proxy statement,
unless the context otherwise requires, the terms "Southern Peru", "SPCC" and the
"Company" refer to the present corporation as well as its predecessor.

      Any proxy in the enclosed form given pursuant to this solicitation and
received in time for the annual meeting will be voted with respect to all shares
represented by it and in accordance with the instructions, if any, given in such
proxy. If the Company receives a signed proxy with no voting instructions given,
such shares will be voted for the election of directors and approval of
accountants proposals. Any proxy may be revoked at any time prior to the
exercise thereof by notice from the stockholder, received in writing by the
Secretary, or by written ballot voted at the meeting.

      The outstanding shares of the Company consist of Common Stock and Class A
Common Stock, par value $0.01 per share (the "Class A Common Stock"). At the
close of business on March 10, 2000, the record date for the annual meeting, the
Company had outstanding 14,095,792 shares of Common Stock and 65,900,833 shares
of Class A Common Stock. Each such share of Common Stock is entitled to one vote
at the meeting, and each such share of Class A Common Stock is entitled to five
votes, except with respect to the election of directors, as described below
under "Voting Securities" or as required by law.

                                Voting Securities

      The Company's Restated Certificate of Incorporation (the "Certificate")
provides for a Board of Directors composed of fifteen directors. Two directors
are elected by the holders of Common Stock (the "Common Stockholders") voting as
a separate class, with each share of Common Stock outstanding at the March 10,
2000 record date entitled to one vote at the annual meeting. Thirteen directors,
one of whom is the President, are nominated and elected by the holders of Class
A Common Stock, voting as a separate class and in accordance with the terms of
an agreement (the "Stockholders' Agreement") among ASARCO Incorporated
("Asarco"), Cerro Trading Company, Inc. ("Cerro") and Phelps Dodge Overseas
Capital Corporation ("Phelps Dodge"). Asarco, Cerro and Phelps Dodge are
hereinafter referred to collectively as the "Class A Common Stockholders." On
November 15, 1999, Asarco transferred all of its holdings of SPCC to Southern
Peru Holdings Corporation ("SPHC"), a wholly-owned subsidiary of Asarco. On
November 17, 1999, Grupo Mexico, S.A. de C.V. ("Grupo Mexico") acquired all the
holdings of Asarco following a tender offer and purchase of all outstanding
common stock of Asarco. Accordingly, SPHC became the holder of all Class A
Common Stock previously held by Asarco and pursuant to the Stockholders'
Agreement, SPHC and Asarco are entitled to nominate and elect directors to serve
on the SPCC Board.


                                       2
<PAGE>

      In accordance with the Company's Certificate, except with respect to the
election of directors or as required by law, the Common Stockholders and Class A
Common Stockholders vote together as a single class. Each share of Common Stock
is entitled to one vote per share and each share of Class A Common Stock is
entitled to five votes per share on matters submitted to the vote of
stockholders voting as one class.

      The Company's By-Laws provide that the presence in person or by proxy of
the Common Stockholders of record of a majority of the shares of Common Stock
entitled to vote at the meeting shall constitute a quorum for the purpose of
electing two directors to represent the holders of Common Stock. Abstentions,
votes withheld and broker non-votes are counted for quorum purposes but are not
counted either as votes cast "For" or "Against". A plurality of the votes cast
by Common Stockholders is required for the election of the two Common Stock
directors. The presence in person or by proxy of the holders of record of a
majority of the combined outstanding shares of Common Stock and Class A Common
Stock entitled to vote at the meeting shall constitute a quorum for purposes of
voting on proposals other than the election of directors. The affirmative vote
of a majority of the votes cast at the meeting by the holders of shares of
Common Stock and holders of shares of Class A Common Stock entitled to vote
thereon, voting as a single class, is required to approve the independent
accountant proposal described in this proxy statement.

      When a Common Stockholder participates in the Dividend Reinvestment Plan
applicable to the Company's Common Stock, his proxy to vote shares of Common
Stock will include the number of shares held for him by The Bank of New York,
the agent under the plan. If the Common Stockholder does not send any proxy, the
shares held for his account in the Dividend Reinvestment Plan will not be voted.
Shares of Common Stock owned under the Company's Savings Plan will be voted by
the trustee under the plan in accordance with the instructions contained in the
proxy submitted by the beneficial Common Stockholder. Any shares held by the
trustee for which no voting instructions are received will be voted by the
trustee in the same proportion as the shares for which voting instructions have
been received.

                              Election of Directors

      Pursuant to a resolution of the Board of Directors adopted on February 25,
2000 two nominees are proposed for election by the Common Stockholders at the
annual meeting. Ambassador Everett E. Briggs and John F. McGillicuddy are the
nominees designated to be voted on by the Common Stockholders. The nominees to
be voted on by the Class A Common Stockholders are Manuel Calderon Cardenas,
Hector Calva Ruiz, Jaime Claro, Alberto de la Parra Zavala, Hector Garcia de
Quevedo Topete, Xavier Garcia de Quevedo Topete, Oscar Gonzalez Rocha, Manuel J.

Pritzker, Daniel Tellechea Salido and J. Steven Whisler. Charles B. Smith and
Douglas C. Yearley will not stand for re-election.

      All of the nominees, except for Messrs. Hector Garcia de Quevedo Topete
and Manuel J. Iraola, are currently serving as directors.

      Proxies in the enclosed form will be voted, unless authority is withheld,
for the election of the two nominees named below. If any person should be
unavailable for election, proxies will be voted for another individual chosen by
the Board of Directors as a substitute for the unavailable nominee.

(a)   The Company's Certificate provides that, except with respect to the
      election of directors or as required by law, the Common Stock and the
      Class A Common Stock vote together as a single class, with each share of
      Common Stock entitled to one vote and each share of Class A Common Stock
      entitled to five votes.

(b)   A subsidiary of ASARCO Incorporated, a wholly-owned subsidiary of Grupo
      Mexico, S.A. de C.V. On November 17, 1999 Grupo Mexico acquired the
      outstanding common stock of Asarco following a tender offer. The stock of
      Southern Peru Holdings Corporation was pledged by Asarco to a syndicate of
      banks in connection with the financing of the tender offer.

(c)   A subsidiary of The Marmon Corporation.

(d)   A subsidiary of Phelps Dodge Corporation.

      The Class A Common Stockholders have entered into the Stockholders'
Agreement, which contemplates, among other things, a Board of Directors composed
of 15 members, one of whom is the President of the Company.

      Under the terms of the Stockholders' Agreement, each Class A Common
Stockholder has the right to nominate that number of 12 directors which is in
proportion to the percentage of Class A Common Stock owned by it (or its
affiliates) out of the aggregate Class A Common Stock then owned by all holders
of Class A Common Stock (without any minimum required number of shares), rounded
to the nearest whole director, with 0.5 being rounded up. If this would result
in the Class A Common Stockholders, as a group, being entitled to elect a number
other than 12 directors, the Stockholders' Agreement contains a formula for
rounding up or rounding down as necessary to apportion the 12 directors among
the Class A Common Stockholders. The Class A Common Stockholders have also
agreed to nominate and vote for the President as a director.

   The Stockholders' Agreement terminates, and each share of Class A Common
Stock automatically converts into one share of Common Stock (voting share for
share as a single class on all matters including election of directors), if at
any time the number of shares of Class A Common Stock owned by the Class A
Common Stockholders (or affiliates of the Class A Common Stockholders) is less
than 35% of the outstanding shares of Class A Common Stock and Common Stock of
the Company. In addition, the rights

and obligations of each Class A Common Stockholder under the Stockholders'
Agreement terminate in the event such Class A Common Stockholder (or its
affiliates) ceases to own shares of Class A Common Stock.

Committee Reports on Executive Compensation

   Compensation Committee

      The Compensation Committee of the Board of Directors of the Company
furnished the following report on compensation of executive officers in 1999.
Since December 17, 1999, this Committee is composed of the entire Board of
Directors. From January 1999 to December 17, 1999, the members of the
Compensation Committee were Messrs. Kevin R. Morano, Richard de J. Osborne,
Robert A. Pritzker and Douglas C. Yearley. The Committee met three times in
1999.


                                       9
<PAGE>

      During 1999, the Compensation Committee considered and made
recommendations to the Board of Directors with respect to the base salaries of
the Company's executive officers, other than those executive officers who are
also officers of, and compensated by, Asarco.

      The 1999 target levels for the base salaries of the executive officers
were determined with the assistance of an independent compensation consulting
organization which established target compensation levels for each position
based on competitive data and the responsibilities and value of each executive
position. The Compensation Committee considered compensation information from
other companies in the mining and metals industry and comparably sized and both
larger and smaller companies in other industries. The Compensation Committee
then considered individual and corporate performance in establishing salary
levels within a competitive range.

      The Compensation Committee set base salaries at levels intended to be
competitive with the Company's industry peers. The Committee also considered the
Company's performance relative to its industry peers. In this regard, the
Company's success in meeting transactional, operational and financial objectives
was taken into consideration. In 1999, for executive officers other than Mr.
Smith, base salaries were increased by an average of approximately 3.5%. In
1999, Mr. Smith was awarded a promotional salary adjustment of 15.8%, and a
salary increase of 5.5% in recognition of his performance, which exceeded
expectations. In late 1999, there was a reorganization in the SPCC management
structure with the replacement of, among others, Mr. Charles B. Smith by Mr.
Oscar Gonzalez Rocha as President. All the Grupo Mexico officers, including Mr.
Gonzalez Rocha, serving as executive officers of SPCC received no compensation
from the Company for 1999 for services other than as directors. Mr. Gonzalez
Rocha is expected to participate in the Company's compensation program beginning
March 2000.

      The Compensation Committee did not award cash incentive compensation to be
paid to each of the Company's executive officers with respect to 1999
performance. Annual cash incentive payments to key salaried employees of the
Company are determined by the Compensation Committee under the Southern Peru
Copper Corporation Incentive Compensation Plan. A target level of annual
incentive compensation is established for each eligible employee based on the
level of responsibility attached to such employee's position. For executive
officers these targets are set at competitive median levels. The officers'
levels of responsibility are determined by the Compensation Committee after
review of substantially equivalent positions among the Company's peers.

      Under the Incentive Compensation Plan, awards to employees are increased
or decreased from a predetermined target level, based upon performance measured
in the areas of production, safety and environmental at two levels: individual
and Company-wide.

      Under Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Internal Revenue Code"), the Company may not deduct, with certain exceptions,
compensation in excess of $1 million to the Chief Executive Officer and the four
other highest paid executive officers as required to be reported in the
Company's proxy statement. The Compensation Committee does not believe that
Section 162(m) will have any immediate material impact on the Company because,
among other things, the principal taxing jurisdiction is Peru. The Compensation
Committee will, however, continue to monitor the Company's executive
compensation programs to ensure their effectiveness and efficiency in light of
the Company's needs, including Section 162(m).

Stock Incentive Plan Committee

      The Stock Incentive Plan Committee of the Board of Directors of the
Company administers the Company's Stock Incentive Plan. The members of the
Committee are Amb. Everett E. Briggs and Mr. John F. McGillicuddy. The Committee
met twice in 1999.

      The Committee selects officers and other employees for participation and
decides upon the timing, pricing and amount of awards and benefits granted under
the Stock Incentive Plan. The members of the Stock Incentive Plan Committee are
non-employee directors who satisfy the requirements of Rule 16b-3 under the
Securities Exchange Act of 1934, as amended.

      Long-term incentive compensation awarded in 1999 consisted of awards of
restricted stock and/or stock options and was designed to link the interests of
executive officers and selected employees with those of stockholders by
providing an incentive to manage the business of the Company as an owner with an
equity stake. Awards in 1999 were to selected officers and employees, and were
made within long-term incentive targets based upon analyses by the Company's
compensation consultant and consideration of each executive's and employee's
performance. In the case of the Chief Executive Officer, the Committee also
considered his performance and responsibility in directing the Company's
performance.

(a)   Other Annual Compensation consists mainly of Company-sponsored programs
      that relate to the geographic distance of the Company's operations from
      countries from which employees are recruited, and address the Company's
      need to recruit and retain certain qualified employees in those employment
      positions in Peru in which their services are needed by the Company. The
      Company also sponsors programs to recruit and retain qualified Peruvian
      employees. During 1999, the expatriates' programs included: a foreign
      service premium, a program reimbursing travel costs for the employee and
      his family to travel back to their home country, an educational assistance
      program, a vacation payment program, and a program awarding a housing
      allowance to employees residing in Lima. Compensation amounts exceeding
      25% of a named officer's total Other Annual Compensation in 1999 were as
      follows: Charles G. Preble, a $31,595 foreign service premium and a
      $80,098 vacation payment; Charles B. Smith, a $87,537 foreign service
      premium and a $111,121 vacation payment; David J. Thomas, a $73,873
      foreign service premium and a $42,000 educational assistance; and Eduardo
      Santistevan, a $41,556 foreign service premium and a $35,000 housing
      allowance. Mr. Santistevan is the brother-in-law of Mr. Preble.

(b)   Dollar values of restricted stock awards are shown as of the date of
      grant. Restricted Common Stock awarded under the Company's Stock Incentive
      Plan was forfeited by the Company's executive officers following the
      management restructure in late 1999.

(c)   Amounts shown for 1999 for all named officers include matching
      contributions by the Company under the Company's Savings Plan and its
      Compensation Deferral Plan. The Savings Plan is a 401(k) plan available
      generally to United States and expatriate salaried employees. The
      Compensation Deferral Plan is a non-qualified deferred compensation plan
      that allows eligible employees to defer that portion of their salary that
      could have been deferred under the Savings Plan but for limitations
      imposed by the Internal Revenue Code, and to defer all or part of their
      eligible incentive compensation, as provided in the Plan. Salary deferrals
      are eligible for a Company matching contribution under the Plan.
      Compensation deferred and amounts contributed by the Company may be
      withdrawn subject to certain restrictions and penalties. Deferrals of
      incentive compensation are not eligible for a Company matching
      contribution. Additional components of All Other Compensation are as
      follows. Peruvian law mandates each of these programs.

            Private Pension System (AFP). Pursuant to the requirements of the
      Peruvian private pension fund system (AFP), funds were paid to Messrs.
      Preble, Smith, and Santistevan in amounts of $16,921, $34,035 and $21,251,
      respectively, in 1999.

            Severance Benefit. Peruvian law requires one month of regular income
      each year to be accrued for severance benefits for each employee (whether
      Peruvian or expatriate) working in Peru. Peruvian law requires a deposit
      of one-twelfth of an employee's annual salary, vacation return and service
      award bonus, as applicable, in a bank account of the employee's choosing
      each year. The money accrues interest until the employee terminates
      employment, at which time the employee is eligible to receive the funds.
      Under this program, severance benefits were deposited on behalf of Messrs.
      Smith, Thomas and Santistevan in amounts of $39,086, $21,587 and $24,647,
      respectively, in 1999. Mr. Preble retired in April 1999, and the
      employment of Messrs. Smith, Santistevan and Thomas was terminated
      following the management restructure in late 1999.

            Severance Payments for Termination of Employment Agreement. Pursuant
      to Peruvian laws concerning expatriate employees, Messrs. Smith,
      Santistevan and Thomas received severance benefits upon termination of the
      employment agreements in December 1999 as follows: Mr. Smith, $514,515;
      Mr. Santistevan, $336,210; and Mr. Thomas $262,053.

(d)   Mr. Smith held this position with the Company until December 1999.

(e)   Mr. Preble retired from the Company on April 29, 1999.

(f)   Mr. Thomas commenced service with the Company in July 1997, after having
      previously been employed by the Company from 1977 to 1987.

(1)   Following the management restructure of the Company in December 1999, Mr.
      German Larrea Mota-Velasco became Chairman of the Board and Mr. Oscar
      Gonzalez Rocha became President of the Company. No options were granted to
      either Mr. Larrea or Mr. Gonzalez by the Company in 1999. Mr. Charles G.
      Preble retired on April 29, 1999 and was granted no options in 1999.

(2)   The options were awarded under the Company's Stock Incentive Plan. The
      option price per share equals the fair market value of the Company's
      Common Stock on the date of grant. The options provide for limited rights
      exercisable upon the occurrence of specified events that may materially
      affect the value of the Company's Common Stock and are designated as such
      by the Committee that administers the Plan, including a tender or exchange
      offer for shares of the Company's Common Stock, the replacement of a
      majority of the Board as a result of a proxy contest, a merger or
      reorganization of the Company, or a liquidation or dissolution of the
      Company. If an exercise event occurs, the holder is entitled to receive
      the cash value of the options at the highest market value that the shares
      traded over a period of sixty days preceding the event or, in the event of
      the consummation of a tender offer, the tender offer price, in each case,
      less the exercise price.

(3)   Based on the Black-Scholes option pricing model, a widely recognized
      method of valuing options. The following assumptions were used in
      determining the value of the options using the model: historical
      volatility of 39.6% based on the volatility of the Common Stock as traded
      on the New York Stock Exchange from the start of trading on January 5,
      1996 to April 29, 1999; an annual dividend rate of $0.32


                                       13
<PAGE>

      per share based upon the ten year average dividend rate paid per share; a
      risk free rate of return of 4.7% based on the yield of the five year U.S.
      treasury notes as of the grant date; and exercise of the option five years
      after the grant date. The actual value, if any, an executive may realize
      will depend on the excess of the stock price over the exercise price on
      the date the option is exercised, so that there is no assurance the value
      realized by an executive will be at or near the value estimated by the
      Black-Scholes model. The model is used for valuing market traded options
      and is not directly applicable to valuing stock options granted under the
      Company's Stock Incentive Plan which cannot be sold.

      All outstanding options were exercisable at December 31, 1999, and as of
that date, unexercised options were held as follows: Mr. Preble, 42,000; Mr.
Smith, 31,300; and Mr. Santistevan 8,300.

Option Exercises and Fiscal Year-End Values

      Set forth below is information concerning stock option exercises by named
executive officers during 1999, including the aggregate value of gains on the
date of exercise, the number of shares covered by exercisable options and the

Retirement Plans

      The following table shows the estimated amount of annual retirement income
payable to employees for life, commencing at normal retirement at age 65 in 1999
under the Company's qualified noncontributory defined benefit Retirement
Benefits Plan (the "Retirement Plan"), covering substantially all salaried
employees in the United States and all expatriate employees in Peru, together
with certain employees of subsidiaries, and a supplemental retirement plan (the
"Supplemental Plan"). Benefits are calculated using an average of the highest
consecutive 60 months of the last 120 months of compensation received, minus a
Social Security offset. The Company's funding policy is to contribute amounts to
the Retirement Plan sufficient to meet the minimum funding requirements set
forth in the Employee Retirement Income Security Act of 1974, as amended

      As of December 31, 1999, the following officers had completed the number
of years of service indicated: Charles B. Smith, 7 years; Eduardo Santistevan,
16 years and David J. Thomas, 12 years. The amounts of


                                       15
<PAGE>

covered compensation of such persons for calendar year 1999 were: Charles B.
Smith, $438,650; David J. Thomas, $225,300; Eduardo Santistevan, $218,829, and
consisted of basic salary and bonuses in the year received. Mr. Charles G.
Preble retired as President and Chief Executive Officer on April 29, 1999. Mr.
Santistevan's benefits are offset by 13 years of accrued vested benefits of
$31,724 (reflecting a straight life annuity benefit assuming normal retirement
at age 65) payable to him under the Company's nonqualified noncontributory
defined benefit Retirement Plan and Trust for Selected Employees (the "Offshore
Pension Plan"). Under the Offshore Pension Plan, selected non-U.S.-citizen
expatriate salaried employees in Peru accrued benefits calculated as 1.5% of the
employee's final salary rate multiplied by the number of years of the employee's
credited service. The benefits are not subject to any offset for Peruvian
governmental benefits. Effective January 1, 1997, covered employees under the
Offshore Pension Plan ceased to accrue benefits under the Offshore Pension Plan
and began to participate in and accrue benefits under the Retirement Plan.

Severance Benefit

      As described in Note (c) to the Summary Compensation Table above, the
Company provides severance benefits as required by Peruvian law.

Employment Agreements

      Pursuant to Peruvian laws concerning expatriate employees, Messrs. Smith,
Santistevan and Thomas had entered into employment agreements. These contracts
generally are for terms of three years and may be extended for additional
periods. Pursuant to Peruvian law, those expatriate employees whose spouses
and/or children are Peruvian citizens have agreements for unlimited terms. Of
the three such named executive officers, Mr. Santistevan has an agreement with
unlimited terms. In accordance with the terms of the contracts, the Company
agrees to provide expatriate employees with benefits as required by Peruvian
Law. The contracts provide that the Company may dismiss expatriate employees for
certain serious offenses. In other instances of termination, the Company is
required to provide 90 days' notice of termination. Terminated employees are
also entitled to receive severance benefits as required by Peruvian law. Under
the contracts, employees may resign at any time by providing the Company with 30
days' notice. Following the reorganization of the management structure of the
Company, the employment agreements for Messrs. Smith, Santistevan and Thomas
were terminated.

Certain Transactions

      Asarco provides various support services to the Company. In 1999, these
activities were principally related to accounting, legal, tax, treasury, price
risk assessment and hedging and administrative support services. Asarco is
reimbursed for these support services. The total amount paid by the Company to
Asarco for such services in 1999 was $800,000.

      During 1999, the Company contracted an aggregate of approximately $8.3
million for shipping services to and from Peru by Cia. Sud Americana de Vapores,
S.A. ("CSAV"), and a subsidiary company. CSAV is a company indirectly controlled
by Quemchi, S.A. Mr. Jaime Claro is Vice Chairman of Electro and Quemchi,


                                       17
<PAGE>

S.A., and his direct and indirect family interests in both companies exceed 10%.
Mr. Claro is also Chairman of Chilean Line Inc., which is the agent for and is
owned by CSAV.

      The Company believes that the foregoing transactions were entered into on
arm's-length bases on terms as favorable as could be obtained from other third
parties. It is anticipated that in the future the Company will enter into
similar transactions with the same parties.

Additional Information

      The functions of the Compensation Committee, include making
recommendations to the Board with respect to election of and title changes for
all corporate executive officers and is composed of members of the entire Board.

      The Nominating Committee, composed of Messrs. German Larrea Mota-Velasco,
Genaro Larrea Mota-Velasco, Xavier Garcia de Quevedo Topete, Amb. Everett E.
Briggs and John F. McGillicuddy, did not meet in 1999. The Nominating Committee
considers and makes recommendations to the Board of Directors with respect to
the nominations, tenure policy and committee assignments for directors
representing the Common Stockholders. The Committee considers recommendations
for nominees to the Board of Directors from all sources. Recommendations for
nominees to represent the Common Stockholders should be sent in writing to the
Secretary of the Company. Common Stockholders are entitled to elect two
directors, voting as a separate class. The Company's By-Laws define notice
procedures to be followed by Common Stockholders seeking to nominate directors
for election. Under the By-Laws, a Common Stockholder seeking to nominate a
director for election by Common Stockholders must give written notice to the
Secretary of the Company at least 90 days in advance of the anniversary date of
the immediately preceding annual meeting, or within 10 days of the giving of
notice of a special meeting. The notice must provide specific biographical data
with respect to each nominee, including such information as is required to be
included in the Company's proxy statement, and a representation by the Common
Stockholder that he or she is a holder of record entitled to vote at the meeting
and that he or she intends to appear in person or by proxy to make the
nomination. Nominations for the Company's 2001 annual meeting of stockholders
must be received by January 29, 2001.

      The Board of Directors met five times in 1999, with 100% attendance by
Messrs. Briggs and McGillicuddy, the two directors representing holders of
Common Stock. Of the 13 directors representing Class A Common Stock, all of the
directors standing for reelection by the holders of Class A Common Stock
attended at least 60% of the aggregate number of meetings of the Board and of
the committees on which they served, with the exception of Mr. Pritzker, who
attended 20% of such meetings. There was one meeting of the Executive Committee
during 1999, with 100% attendance by all members.

Compensation of Directors

      During 1999 directors who were not compensated as employees of the Company
were paid a basic fee of $15,000 plus $1,000 for attendance at each meeting of
the Company's Board or of any Committee of the Board. The Company has a
Directors' Stock Award Plan pursuant to which directors who are not compensated
as employees of the Company are entitled to an award of 200 shares of Common
Stock upon election to the Board and 200 additional shares of Common Stock
following each annual meeting of stockholders thereafter.

      Under the Deferred Fee Plan for Directors, a director may elect to defer
payment of 50% or 100% of the compensation payable to such director for Board
and Committee service for the calendar year for which deferral is elected.
Deferred amounts will be credited to a cash subaccount, a company common stock
subaccount or a combination thereof. Compensation deferred to the cash
subaccount will earn interest based on U.S. Treasury debt obligations with a
10-year maturity. Compensation deferred to the stock subaccount will be credited
as whole shares of Common Stock based on the stock's fair market value on the
date of such credit. Dividends and fractional share amounts will be aggregated
until at least one share of Common Stock may be credited at the then fair market
value. Payments will be made in cash in a lump sum upon retirement


                                       18
<PAGE>

as a director on January 15 of the calendar year following normal retirement, or
promptly following the date of termination if the termination of service occurs
at a date prior to his normal retirement date. The Plan permits early withdrawal
or further deferral of participant accounts, subject to financial hardship,
prior notice or penalty requirements.

Compensation Committee Interlocks and Insider Participation

      During 1999, Jaime Claro attended meetings of the Compensation Committee
as an alternate in the absence of Robert A. Pritzker. Mr. Claro received no
compensation from the Company during 1999 for services other than as a director.
See "Certain Transactions" above for information regarding related transactions
concerning this director.

Section 16(a) Beneficial Ownership Reporting Compliance

      Based on Company records and other information, the Company believes that
all filing requirements of the Securities and Exchange Commission applicable to
its executive officers and Directors were complied with for 1999, except for Mr.
Eduardo Santistevan, a former Vice President, who filed a late report covering
one transaction when no longer in the Company's employment.

                Proposal to Approve the Selection of Accountants

      The Board of Directors has selected Arthur Andersen L.L.P. to serve as
independent accountants for the Company for the calendar year 2000, subject to
approval of the stockholders. The Board of Directors recommends that the
stockholders approve the selection of Arthur Andersen L.L.P. at the annual
meeting. Arthur Andersen L.L.P. replaces PricewaterhouseCoopers L.L.P.
PricewaterhouseCoopers L.L.P. and its predecessors had served as the Company's
accountants continuously since 1962. Arthur Andersen L.L.P. has had more than 25
years of experience with Grupo Mexico, providing outstanding professional
services. Arthur Andersen L.L.P. is a world-class global auditing and consulting
firm with excellent mining industry credentials in the primary mineral producing
countries of the world. Arthur Andersen L.L.P. has advised the Company that
neither the firm nor any of its members have any direct or material indirect
financial interest in the Company or its subsidiaries. A representative from
PricewaterhouseCoopers L.L.P., the Company's former independent accountants,
will not be present at the stockholders' meeting. There were no disagreements
with PricewaterhouseCoopers L.L.P. on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure.

      The Audit Committee consists of Amb. Everett E. Briggs and Mr. John F.
McGillicuddy. Three meetings were held in 1999. The functions of the Committee
include recommending the engagement of independent accountants, reviewing the
fees, scope and timing of their other services, and reviewing the audit plan and
results of the audit. The Committee also reviews the Company's policies and
procedures on internal auditing, accounting and financial controls. The
implementation and maintenance of internal controls are understood to be
primarily the responsibility of management.

      A representative of Arthur Andersen L.L.P. will be present at the
stockholders' meeting. The representative will have an opportunity to make a
statement and will be available to respond to appropriate questions.

To the Common Stockholders of
  Southern Peru Copper Corporation

                                   A REMINDER

      We have previously sent to you proxy soliciting material relating to the
annual meeting of stockholders to be held on May 9, 2000.

      According to our latest records, we have not as yet received your Proxy.
The time before the meeting is short and many of our shares are held in small
amounts. Your signed Proxy will be helpful, whether your holding is large or
small, and will aid us in avoiding further expense and delay.

      A Proxy and return envelope are enclosed for your use. You may also return
your Proxy to the Company's Lima office.

      Thank you for your cooperation.

                                                      Very truly yours,


                                                      Robert Ferri
