Item 1. Business

                                   THE COMPANY

The Company, an integrated producer of copper, operates mining, smelting and
refining facilities in the southern part of 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 of the Company's Peruvian Branch ("Labor Shares")
called "Investment Shares" as of December 31, 1998. Effective December 31, 1998,
the Company's predecessor and wholly owned operating subsidiary, Southern Peru
Limited, was merged into the Company.

The Company, incorporated in 1952 was reorganized in 1955 and has conducted
copper mining operations since 1960. Pursuant to Peruvian law, the Company
conducts its operations in Peru through a registered branch (the "Branch"). The
Branch is not a corporation separate from the Company. It is, however, an
establishment, registered pursuant to Peruvian law, through which the Company
holds assets, incurs liabilities and conducts operations in Peru. Although it
has neither its own capital nor liability separate from that of the Company, it
is deemed to have an equity capital for purposes of determining the economic
interest of holders of investment shares. Investment shares are non-voting
ownership interests distributed to workers in accordance with former Peruvian
laws. The Branch comprises substantially all the assets and liabilities of the
Company associated with its copper operations in Peru.

Throughout this report, unless the context otherwise requires, the terms
"Southern Peru", "SPCC" and "the Company" refer to the present corporation and
its consolidated subsidiaries as well as its predecessor. In addition,
throughout this report, unless otherwise noted, all tonnages are in metric tons.
To convert to short tons, multiply by 1.102. All distances are in kilometers. To
convert to miles, multiply by 0.62137. All ounces are troy ounces.

On November 15, 1999, ASARCO Incorporated (ASARCO) transferred all of its
holdings of SPCC to Southern Peru Holdings Corporation, 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.

At December 31, 1999 the stockholders in the Company were Southern Peru Holdings
Corporation, a subsidiary of ASARCO (54.2%), a subsidiary of Cerro Trading
Company, Inc.(14.2%), Phelps Dodge Overseas Capital Corporation (14.0%) and
common stockholders (17.6%).

COPPER BUSINESS

The copper operations of the Company involve the mining, milling and flotation
of copper ore to produce copper concentrates, the smelting of copper
concentrates to produce blister copper and the refining of blister copper to
produce copper cathode.

The Company also produces refined copper using solvent extraction/electrowinning
("SX/EW") technology. Silver, molybdenum and small amounts of other metals are
contained in copper ore as by-products. Silver sold is recovered in the refining
process or as an element of blister copper. Molybdenum is recovered from copper
concentrate in a molybdenum by-product plant. The Company has not reported
information by industry segments because substantially all of its revenues are
generated from its copper production.

                              REVIEW OF OPERATIONS

SPCC operates the Toquepala and Cuajone mines, high in the Andes, approximately
984 kilometers southeast of Lima. It also operates a smelter and refinery west
of the mines at the Pacific Ocean coast City of Ilo, Peru. SPCC is one of Peru's
leading companies and one of the 10 largest private-sector copper mining
companies in the world.

Mine copper production at SPCC increased in 1999 due principally to higher
throughput at the Cuajone mine, following completion of the mine expansion. The
rainy conditions in the first quarter of the year and metallurgical difficulties
with the ore reduced copper production by an estimated 80 million pounds during
the twelve months of 1999. Improved operations at the Ilo copper refinery and
completion of the Toquepala SX/EW facility, increased 1999 refined copper
production.

The Cuajone mine expansion completed earlier this year reached target ore
throughput rate during the second quarter 1999. The expansion of the Toquepala
SX/EW facility, which will increase annual production to 56,250 tons, was
completed in the third quarter of this year. The Company's investment program
includes continuing expansion of the Toquepala mining unit, expansion of the
concentrator and adding equipment in the pit. Likewise, modernization of the
mining equipment at Cuajone will continue and a possible expansion of the
leaching section of such unit and the construction of a SX/EW plant is being
analyzed. Special emphasis will be given to the modernization of the Ilo
smelter, in order to improve its efficiency, its production volume and
significantly increase the capture of sulfur dioxide, to comply with
environmental agreements and requirements.

MINING OPERATIONS

Total mined copper production at SPCC increased 11.9% in 1999, compared with
1998, due to higher production at Cuajone and the beginning of operations in the
fourth quarter of the SX/EW plant expansion.

Cuajone production increased 20.4% in 1999 to 380 million pounds of copper
due principally to higher throughput at the Cuajone mine, following
completion of the mine expansion. Concentrator throughput for the year was
28.6 million tons of ore producing 690,000 tons of copper concentrates. The
rainy conditions in the first quarter of the year and metallurgical
difficulties with the ore reduced copper production by an estimated 80
million pounds from planned levels during the twelve months of 1999.

Toquepala mine production increased 3.9% in 1999 to 256 million pounds of copper
due to an increase in ore grade. The Toquepala concentrator milled 16.2 million
tons of ore. Together, the two mines produced 3.4 million ounces of silver and
12.1 million pounds of molybdenum as by-products.

SX/EW OPERATIONS

The SX/EW facility at Toquepala produces refined copper from solutions obtained
by leaching low-grade ore stored at the Toquepala and Cuajone mines. An
expansion of the facility was completed in the third quarter of 1999 increasing
annual production to 56,250 tons. The facility produced 49,500 tons in 1999
compared to 47,000 tons in 1998. This represents 5.2 million pounds more copper
over 1998 production.

ORE RESERVES

SPCC has identified substantial geologic resources. In October 1999, the Company
reported a substantial increase in proven and probable ore reserves at the
Toquepala mine. At year-end 1999, probable sulfide reserves totaled 692 million
tons with an average copper grade of 0.74% at Toquepala and 1,242 million tons
with an average copper grade of 0.64% at Cuajone. In addition, the Company has
leachable ore, Toquepala with 1,732 million tons with ore grade of 0.20% and
Cuajone with 62 million tons with ore grade of 0.49%.

SMELTING AND REFINING OPERATIONS

The Ilo smelter increased concentrate processed by 4.3% in 1999 as compared to
the prior year. Smelting of SPCC concentrates increased by 17.8%, replacing
higher-grade copper concentrate from third parties. As a result, blister
production decreased by 1.5% in 1999 as compared to 1998.

SPCC's total refined copper production, including the 109.2 million pounds from
the SX/EW plant, increased 2.2% to 662.0 million pounds in 1999 from 647.4
million pounds in 1998. Refined production from the Ilo refinery reached 552.7
million pounds in 1999, an increase of 1.7% from 1998 due to efficiency gains at
the plant.

The SX/EW expansion was completed during the third quarter of 1999 increasing
this facility's production by 5.0% when compared to the prior year.

SPCC's Ilo smelter provides feed for the refinery. Blister copper produced by
the smelter exceeds the refinery's capacity and the excess is sold to other
refineries around the world.

EXPANSION AND MODERNIZATION PROGRAM

Expansion and modernization programs announced in prior years are underway.
Expansion of the Cuajone mine was finished in 1999 with an investment of $245
million. During 1999 the following major equipment was received for the Cuajone
mine: one 4100 model P&H shovel with a capacity of 56 cubic yards, eight 793C
model Caterpillar 240-short ton capacity trucks, one 100XP model P&H rotary
drill, one 844 model Caterpillar wheel tractor and one LT1800 model Letorneau
front-end loader with a capacity of 33 cubic yards. This equipment is already
operating in the mine, with the exception of the P&H shovel, which will start
operations in March 2000. The expansion of the SX/EW plant in Toquepala was
finished in 1999 and is producing at its design capacity of 56,250 tons per
year.

The project to expand and protect the Cuajone mine from maximum flooding of the
Torata river is under construction and reached 40% completion at the end of
1999, with an investment of $36.0 million out of the $75.5 million budget. The
Torata river will be diverted in June 2000 to allow the beginning of the Cuajone
pit expansion.

Engineering studies for the Ilo smelter modernization and expansion project were
continued introducing the most efficient technology, proven in other
metallurgical facilities, looking not only to comply with Peruvian environmental
standards, but also to provide economic returns.

Feasibility studies for expansion of the Toquepala concentrator, its mine, the
leaching section and a SX-EW plant at Cuajone are currently underway.
Construction of these projects may begin in the year 2000 improving SPCC
production capacity to over 900 million pounds of copper per year.

EXPLORATION

SPCC continues with its aggressive exploration program in Peru aimed at finding
economically attractive copper-gold deposits. Currently, the Company owns
330,000 hectares of mining rights and has access to another 108,000 hectares
through joint ventures and purchase options.

7,700 meters have been drilled at Los Chancas project. Preliminary results
indicate up to 200 million tons of ore with a copper content superior to 1%;
0.08% molybdenum; and 0.12 gr./ton of gold. The expected stripping ratio is low.
The first metallurgical tests indicate a ductile metal. More testing is underway
to determine the best way to treat this material. The Tantahuatay project, in
which SPCC has a 44% interest, has leacheable oxides containing a potential of 4
million gold ounces. Studies are currently underway to treat the arsenic content
of the deposit and make feasible the exploitation of the important copper
sulfides deposit located under the gold. Encouraging results have been found in
other gold/copper exploration projects. Work on these prospects will continue
during 2000.

ENVIRONMENT

With the operation of the sulfuric acid plant at the smelter in Ilo, which was
expanded to 317,500 tons per year and the Supplementary Control Program (SCP) to
control sulfur dioxide emissions by curtailing production during periods of
adverse weather, there has been an improvement of air quality in the Ilo area.
Part of the acid produced is used by the company to leach ore at its SX/EW
operation; the balance is sold in regional markets.

                                                                              A5


                         PRINCIPAL PRODUCTS AND MARKETS

The principal uses of copper are in the building and construction industry,
electrical and electronic products and, to a lesser extent, industrial machinery
and equipment, consumer products and the automotive and transportation
industries. Silver is used for photographic, electrical and electronic products
and, to a lesser extent, brazing alloys and solder, jewelry, coinage, silverware
and catalysts. Molybdenum is used to toughen alloy steels and soften tungsten
alloy and is also used in fertilizers, dyes, enamels and reagents.

During 1999, 1998 and 1997, substantially all of the Company's copper production
was exported from Peru and sold to customers in Europe, the Far East, the United
States and elsewhere in Latin America. A substantial portion of SPCC's copper
sales is made under annual contracts to industrial users. Silver is sold under
annual contracts or in spot sales and molybdenum is sold in concentrate form to
merchants and other refiners under annual contracts. Most customers receive
shipments on a monthly basis at a constant volume throughout the year. As a
result there is little seasonality in SPCC sales volumes.

                                BACKLOG OF ORDERS

Substantially all of the Company's metal production is sold under annual
contracts. To the extent not sold under annual contracts, production can be sold
on commodity exchanges or in spot sales. Final sales values are determined based
on prevailing commodity prices for the quotation period, generally being the
month of, the month prior to or the month following the actual or contractual
month of shipment or delivery according to the terms of the contract.

                             COMPETITIVE CONDITIONS

Competition in the copper market is principally on a price and service basis,
with price being the most important consideration when supplies of copper are
ample. The Company's products compete with other materials, including aluminum
and plastics.

                                    EMPLOYEES

At December 31, 1999 the Company employed 3,844 persons, about fifty-eight
percent of whom were covered by labor agreements with nine labor unions. There
were no labor strikes in 1999.

                       ENERGY MATTERS AND WATER RESOURCES

Electric power for the Company's operating facilities is generated by a thermal
electric plant owned and operated by Enersur S.A. and located adjacent to the
Ilo smelter. Power generation capacity is currently 150 megawatts. In addition,
the Company has 30 megawatts of power generation capacity from waste heat
boilers in the smelter and two small hydro-generating installations at Cuajone.
Power is distributed over a 224-kilometer closed loop transmission circuit.

In 1997, the Company sold its Ilo power plant to Enersur S.A. and entered into a
20-year power purchase agreement. The power purchase agreement contains
provisions obligating Enersur S.A. to construct additional capacity upon notice
to meet the Company's increased electricity requirements from the planned
expansion and modernization. The parties also entered into an agreement for the
sharing of certain services between the power plant and the Company's smelter at
Ilo. Under this agreement, the Company's cost of power has increased somewhat
from its 1996 level, while the Company has benefited by avoiding significant
capital expenditures required to meet the needs of the expanded operations.

SPCC has water concessions for well fields at Huaitire and Titijones and surface
water rights from Lake Suches.

                              ENVIRONMENTAL MATTERS

The Company anticipates spending $50 million for environmental control capital
expenditures in 2000. Capital expenditures in connection with environmental
projects were approximately $41.6 million in 1999, $25.3 million in 1998 and
$47.8 million in 1997. See "Management's Discussion and Analysis of Financial
Condition and Results of Operation - Environmental Matters" which is herein
incorporated by reference.

                                   CONCESSIONS

The Company has concessions from the Peruvian government for its exploration,
exploitation, extraction and/or production operations (collectively, the
"Concessions"). The Concessions are in full force and effect under applicable
Peruvian laws, and the Company believes it is in compliance with all material
terms and requirements applicable to the Concessions. The Concessions have
indefinite terms, subject to payment by SPCC of concession fees of up to $2 per
hectare annually for the mining concessions and a fee based on nominal capacity
for the processing concessions. Fees paid during 1999 were approximately $1.2
million.

                                REPUBLIC OF PERU

Substantially all of the Company's revenues are derived from the Toquepala mine,
the Cuajone mine, the SX/EW facility and the smelter and refinery at Ilo, all of
which are located within a 48-kilometer radius in the southern part of Peru.
Risks attendant to the Company's operations in Peru include those associated
with economic and political conditions, effects of currency fluctuations and
inflation, effects of government regulations and the geographic concentration of
the Company's operations.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

OVERVIEW

The Company's business is affected by the factors outlined below which should be
considered in reviewing the financial position, results of operations and cash
flows of the Company for the periods described herein.

Inflation and Devaluation of the Peruvian New Sol: A portion of the Company's
operating costs are denominated in Peruvian New Soles. Since the revenues of the
Company are primarily denominated in U.S. dollars, when inflation in Peru is not
offset by a corresponding devaluation of the New Sol, the financial position,
results of operations and cash flows of the Company could be adversely affected.
The value of the net assets of the Company denominated in new soles can be
affected by devaluation of the new sol. The recent inflation and devaluation
rates are as follows:

Years ended December 31,                          1999        1998        1997
                                                  ----        ----        ----

Peruvian Inflation Rate                            3.7%        6.0%       6.5%
New Sol/Dollar Devaluation Rate                   11.2%       15.7%       4.9%

Peruvian Branch: The consolidated financial statements included herein are
prepared in U.S. dollars and in accordance with generally accepted accounting
principles in the United States (US GAAP). The Peruvian Branch (the Branch)
consists of substantially all the assets and liabilities of Southern Peru Copper
Corporation (SPCC) associated with its copper operations in the Republic of
Peru. The Branch is registered with the Peruvian government as a branch of a
foreign mining company. The results of the Branch are consolidated in the
financial statements of the Company.

The Branch maintains its books of account in new soles and prepares financial
information in accordance with generally accepted accounting principles in Peru
(Peruvian GAAP). Peruvian GAAP requires the inclusion in the financial
statements of the Branch of the Resultado por Exposicion a la Inflacion (Result
of Exposure to Inflation), which seeks to account for the effects of inflation
by adjusting the value of non-monetary assets and liabilities and equity by a
factor corresponding to wholesale price inflation rates during the period
covered by the financial statements. Monetary assets and liabilities are not so
adjusted.

Expansion and Modernization Project: Expansion and modernization programs
announced in prior years are underway. Expansion of the Cuajone mine was
finished in 1999 with an investment of $245 million. During 1999 the
following major equipment was received for the Cuajone mine: one 4100 model
P&H shovel with a 56 cubic yard capacity, eight 793C model Caterpillar 240
short ton capacity trucks, one 100XP model P&H rotary drill, one 844 model
Caterpillar wheel tractor and one LT1800 model Letorneau front end loader
with a 33 cubic yard capacity. This equipment is already operating at the
mine, with the exception of the P&H shovel, which will start operations by
March 2000. The expansion of the SX/EW plant in Toquepala was finished in
1999 and is producing at its design capacity of 56,250 tons per year.

The project to expand and protect the Cuajone mine from maximum flooding of the
Torata River is under construction and reached 40% completion at the end of
1999, with an investment of $36.0 million out of the $75.5 million budget. The
Torata River will be diverted in June 2000 to allow the beginning of the Cuajone
pit expansion.

Engineering studies for the Ilo smelter modernization and expansion project were
pursued until November 1999, at which time management decided to revisit the
available technologies in order to both fulfill the Peruvian environmental
standards, as established in the PAMA, and to better conform the project to
SPCC's

<PAGE>
                                                                             A16


financial capabilities. The alternatives under analysis may consider ways to
speed up the investment commitments as long as they do not compromise SPCC's
economic performance, and offer reasonable returns on the investment. This
review is expected to be completed in the second quarter of 2000 at which time
the best alternative will be selected.

Feasibility studies for expansion of the Toquepala concentrator and a new SX-EW
plant at Cuajone are currently under way. If attractive, construction of these
projects may begin in the year 2000 improving SPCC production capacity to over
900 million pounds per year.

RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

SPCC reported 1999 net earnings of $29.4 million, or diluted earnings per share
of 37 cents, compared with net earnings of $54.6 million, or diluted earnings
per share of 68 cents, in 1998 and net earnings of $185.7 million, or diluted
earnings per share of $2.32, in 1997.

The decline in net earnings in 1999 compared with 1998 is primarily a result of
lower copper prices and higher depreciation charges. The average price of copper
in 1999 on the London Metal Exchange declined 4 cents per pound from 1998 to 71
cents per pound. The earnings decrease was partially offset by savings realized
from the cost reduction program instituted by the Company in 1998.

In April 1998, SPCC initiated cost-reduction and production enhancement
programs, including reductions in operating expenses, purchased services and
general and administrative expenses, designed to reduce annual expense by $30
million when fully implemented. The programs are estimated to have increased
pre-tax earnings by $29.2 million in 1999, improving net after-tax earnings by
$18.8 million, or 24 cents per share. In the year 2000 the programs are expected
to improve net earnings by approximately $40.0 million, or 50 cents per share.

Results for 1999 include a non-recurring after-tax charge of $5.4 million ($8.4
million pre-tax), or 6 cents per share, for the severance cost of foreign
contract employees' early termination. In addition, the 1999 results also
include a non-recurring after-tax charge of $3.6 million ($5.6 million pre-tax),
or 5 cents per share, for severance costs associated with the Company's cost
reduction program.

In connection with the cost reduction program the Company recorded a $10 million
pre-tax charge in the first quarter of 1998 for severance costs. In addition, in
the fourth quarter of 1998 the Company transferred title to a major portion of
the Ilo townsite to its worker occupants and the City of Ilo. Titles to 1,344
individual homesites were transferred. The Company recorded a pre-tax charge of
$10.9 million in 1998 to write-off the remaining book value of the transferred
property and to provide for other costs associated with the divestiture. The
Company expects future savings as a result of the transfer of the townsite
through reduced maintenance costs.

The decline in net earnings in 1998 compared with 1997 is primarily a result of
lower copper prices. The average price of copper in 1998 on the London Metal
Exchange declined 28 cents per pound from 1997 to 75 cents per pound, and at
year-end 1998 was 66 cents per pound. In addition to lower metal prices, results
for 1998 also reflect an increase in the effective income tax rate compared to
1997. The earnings decrease was partially offset by savings realized from the
cost reduction program instituted by the Company in 1998.

In 1997, the Government of Peru approved a reinvestment allowance for the
Company's program to expand the Cuajone mine. Pursuant to the reinvestment
allowance, the Company receives certain tax incentives in Peru. As a result,
U.S. tax credit carryforwards for which no benefit had previously been recorded
were utilized. Principally because of the reinvestment program, the Company's
effective tax rate was lower in 1997.

As a result of the expansion program, electric power requirements will increase
significantly requiring the construction of additional generating capacity. In
the second quarter of 1997, the Company sold its existing power plant to an
independent power company for $33.6 million. In connection with the sale, a
power purchase agreement was also completed, under which the Company agreed to
purchase its power needs for twenty years. Under the agreement, the cost of
power has increased somewhat from its 1996 level; however, the Company will
avoid the significant capital expenditures that would be required to meet the
needs of expanded operations.

Net Sales: Net sales in 1999 were $584.5 million, compared with $627.9 million
in 1998 and $814.2 million in 1997. Sales decreased in 1999 by $43.4 million,
largely as a result of lower copper prices. Copper sales volume was 2.2 million
pounds lower in 1999 compared with 1998.

Sales decreased in 1998 by $186.3 million from 1997, largely as a result of
lower copper prices, offset somewhat by an increase in copper and molybdenum
volume. Copper sales volume was 8.1 million pounds higher in 1998 compared with
1997. Sales of copper produced at Company mines, however, decreased by 6.5
million pounds in 1998 as compared with 1997.

At December 31, 1999, there were no copper sales recorded at provisional prices.

Prices: Sales prices for the Company's metals are established principally by
reference to prices quoted on the London Metal Exchange (LME), the New York
Commodity Exchange (COMEX) or published in Platt's Metals Week for dealer oxide
mean prices for molybdenum products.

(1)   The Company's molybdenum production is sold in concentrate form. Volume
      represents pounds of molybdenum contained in concentrates.

Financial Instruments: The Company may use derivative instruments to manage its
exposure to market risk from changes in commodity prices. Derivative instruments
which are designated as hedges must be deemed effective at reducing the risk
associated with the exposure being hedged and must be designated as a hedge at
the inception of the contract.

Copper: Depending on the market fundamentals and other conditions, the Company
may purchase put options to reduce or eliminate the risk of price declines below
the option strike price on a portion of its anticipated future production. Put
options purchased by the Company establish a minimum sales price for the
production covered by such put options and permit the Company to participate in
price increases above the option price. The cost of options is amortized on a
straight-line basis during the period in which the options are exercisable.
Depending upon market conditions, the Company may either sell options it holds
or exercise the options at maturity. Gains or losses from the sale or exercise
of options, net of unamortized acquisition costs, are recognized in the period
in which the underlying production is sold and are reported as a component of
the underlying transaction.

Earnings include pre-tax gains from option sales and exercises of $7.2 million
in 1998 and $10.2 million in 1997. At December 31, 1999, the Company held no
copper put options.

Fuel Swaps: The Company may enter into fuel swap agreements to limit the effect
of increases in fuel prices on its production costs. A fuel swap establishes a
fixed price for the quantity of fuel covered by the agreement. The difference
between the published price for fuel and the price established in the contract
for the month covered by the swap is recognized in production costs. As of
December 31, 1999 and 1998, the Company had the following fuel swap agreements:

                                                           Weighted

1999
Residual Oil               1/00-12/00       1,468,800       $12.80
Diesel Fuel                1/00-12/00         504,000       $19.36

1998
Residual Oil               1/99-9/99        1,095,000       $ 9.84
Diesel Fuel                1/99-9/99          432,000       $15.80

The unrealized gain in the Company's fuel swap positions at December 31, 1999
was $8.7 million. The effect of a hypothetical 10 percent decrease from December
31, 1999 fuel prices would be to reduce the unrealized gain on fuel swaps by
$3.7 million.

In 1999, the Company's production costs would have been $10.7 million higher if
this exposure had not been hedged.

Foreign currency: The Company selectively uses foreign currency swaps to limit
the effects of exchange rate changes on future cash flow obligations denominated
in foreign currencies. A currency swap establishes a fixed dollar cost for a
fixed amount of foreign currency required at a future date. The Company has
entered into currency swap agreements on a portion of its capital cost
contracted in Euros.

The unrealized loss in the Company's currency swap position at December 31, 1999
was $3.3 million. A hypothetical 10 percent decrease from December 31, 1999
rates, would increase the unrealized loss on currency swaps by $2.9 million. The
full cost of the currency swap amounts as acquired will, when exercised, be
included in the cost of the capital asset for which these swaps were obtained.

Cost of Sales: Cost of sales was $410.1 million in 1999, $446.5 million in 1998
and $474.4 million in 1997. The decrease of $36.4 million in 1999 includes the
lower cost of copper processed and sold from purchased concentrates, the lower
unit cost of company mined copper as a result of decreases in power and fuel
costs, and benefits from the Company's cost reduction program. These decreases
were offset in part by a $14.8 million charge for severance costs, which were
part of the Company's earnings enhancement program.

The decrease of $27.9 million in 1998 was principally due to the lower sales
volume of copper produced from third parties' concentrates and lower power and
fuel costs, partially offset by a $10.0 million charge for severance cost and a
$10.9 million charge for Ilo townsite divestiture cost, which were part of the
Company's earnings enhancement program

Other Expenses: Depreciation and depletion expense was $74.2 million in 1999,
compared with $60.9 million in 1998 and $46.7 million in 1997. The increase in
1999 includes depreciation of the new ball mills of the Cuajone concentrator as
well as mining equipment of the Cuajone mine expansion and the expansion of the
SX/EW plant in Toquepala. The increase in 1998 includes depreciation of the
tailings dam facility completed in late 1997, the acid plant expansion completed
in 1998 and the addition of haul trucks in 1998 and 1997.

Exploration expenses were $7.2 million, $5.2 million and $7.4 million in 1999,
1998 and 1997, respectively. The increase in 1999 reflects the increase of
drilling programs at the Company's exploration properties.

Non-Operating Items: Interest income was $7.8 million in 1999 compared with
$15.8 million in 1998 and $20.9 million in 1997. The decreases in 1999 and 1998
reflects the lower invested balances as funds were utilized in the Company's
expansion program. Interest income is expected to continue to decrease as
available cash is used to fund the Company's expansion and modernization
program.

Other income was $3.6 million in 1999 compared with $9.4 million in 1998 and
$7.1 million in 1997. Other income in 1998 includes a $5.3 million insurance
settlement related to flood damage, which occurred in 1997.

Total interest expense was $25.2 million in 1999, compared with $25.6 million in
1998 and $21.9 million in 1997. In 1999, 1998 and 1997, the Company capitalized
$7.3 million, $10.6 million and $2.3 million of interest, respectively,
principally related to expenditures on the expansion program.

Taxes on Income: Taxes on income were $9.7 million, $25.6 million and $55.6
million for 1999, 1998 and 1997, respectively, and includes $11.6 million, $22.9
million and $45.0 million of Peruvian income taxes and $(1.9) million, $2.7
million and $10.6 million, for U.S. federal and state taxes for 1999, 1998 and
1997, respectively. U.S. income taxes are primarily attributable to investment
income as well as limitations on use of foreign tax credits in determining the
alternative minimum tax.

In 1997, the Government of Peru approved a reinvestment allowance for the
Company's program to expand the Cuajone mine. The reinvestment allowance
provides the Company with tax incentives in Peru and, as a result, certain U.S.
tax credit carryforwards, for which no benefit had previously been recorded,
were realized. The reduction in the Company's effective tax rate, as a result of
the reinvestment allowance, lowered tax expense by approximately $14.7 million
in 1997. Pursuant to the reinvestment allowance the Company has received tax
deductions in Peru in amounts equal to the cost of the qualifying property
(approximately $245 million). The financial statement carrying value of the
qualifying property was reduced to reflect the tax benefit associated with the
reinvestment allowance (approximately $73 million). As a result, financial
statement depreciation expense related to the qualifying property will be
reduced over its useful life (approximately 15 years).

The Company obtains income tax credits in Peru for value-added taxes paid in
connection with the purchase of capital equipment and other goods and services
employed in its operations and records these credits as a prepaid expense. Under
current Peruvian law, the Company is entitled to use the credits against its
Peruvian income tax liability or to receive a refund.

Minority Interest of Investment Shares (previously known as Labor Shares): There
was no minority interest of investment shares in 1999, compared to $0.5 million
in 1998 and $4.4 million in 1997. The provision for minority interest of
investment shares represents an accrual of 1.7%, 2.0% and 2.4% for 1999, 1998
and 1997, respectively, of the Branch's after-tax earnings. The reductions in
the percentage of minority interest of investment shares in 1999 and 1998 is a
result of purchases of investment shares by the Company.

Cash Flows - Operating Activities: Net cash provided from operating activities
were $90.3 million in 1999, compared with $186.6 million in 1998 and $277.6
million in 1997. The decrease in 1999 was primarily attributable to an $81.1
million higher use of cash for operating assets and liabilities, which includes
$25.8 million for an increase in accounts receivable because of the higher
copper prices late in 1999 and $41.0 million increase in inventories of
purchased concentrates, refined copper and supplies. Additionally, $25.2 million
of lower earnings partially offset by $13.3 million of higher depreciation and
depletion contributed to the decrease in operating cash flow. The decrease in
1998 was primarily attributable to lower copper prices. The decrease in 1998
reflects lower earnings of $131.1 million partially offset by higher
depreciation and deferred tax provisions of $14.1 million and $21.7 million,
respectively.

Cash Flows - Investing Activities: Net cash used for investing activities was
$227.5 million in 1999 compared with $75.9 million in 1998 and $337.6 million in
1997. Capital expenditures in 1999 were $250.3 million, compared with $258.7
million in 1998 and $184.0 million in 1997.

Capital expenditures in 1999, 1998 and 1997 reflect the Company's expansion and
modernization program and capitalization of mine stripping. Other investment
activities in 1999 and 1998 include net proceeds of $22.2 million and $182.4
million, respectively, from held-to-maturity investments. These investments were
utilized in the Company's expansion programs.

The Company's planned capital expenditures in 2000 are estimated to be
approximately $269 million, which includes expenditures related to the
modernization and expansion of the Ilo smelter, feasibility studies for the
expansion of the Toquepala concentrator and a SX/EW plant in Cuajone and the
Torata River Flood Control project.

Cash Flows - Financing Activities: Financing activities used cash of $27.3
million and $59.5 million in 1999 and 1998, respectively, compared to a source
of cash of $11.8 million in 1997. In 1999 activity included dividend payments of
$12.2 million, net debt repayment of $11.7 million and purchases of investment
shares of $3.4 million.

Included in 1998 uses of cash are debt repayments of $13.7 million, purchases of
investment shares of $3.8 million and net treasury stock transactions of $2.7
million.

LIQUIDITY AND CAPITAL RESOURCES

Financing: In March 1999, the Company concluded a $100 million, 15-year loan
agreement with Mitsui and Co., Ltd. The applicable interest for this loan is the
LIBO rate plus 1.25%. This facility provides additional committed financing for
SPCC's modernization and expansion program. A commitment fee of 0.5% per annum
is payable on the undrawn portion of this loan through December 31, 2001. As of
December 31, 1999 $2.0 million had been drawn from this loan facility.

In 1997, the Company entered into a $600 million, seven year loan facility with
a group of international financial institutions. The facility consists of a $400
million term loan and a $200 million revolving credit line. The interest rate
during the first three years of the agreement on any loans outstanding is LIBOR
plus 1.75% per annum for term loans and LIBOR plus 2.0% for revolving credit
loans. A commitment fee of 0.5% per annum is payable on the undrawn portion of
the facility. No amounts had been drawn under this agreement as of December 31,
1999.

Also in 1997, the Company privately placed $150 million secured export (SENS) in
the United States and international markets. These notes, which have been
registered with the Securities and Exchange Commission, begin amortizing in 2000
and mature in 2007 and were priced at par with a coupon rate of 7.9%. In
addition, in 1997 the Company sold $50 million of bonds, due June 2004, to
investors in Peru. The bonds have a fixed interest rate of 8.25%. The Company
expects that it will meet its cash requirements for 2000 and beyond from
internally generated funds, cash on hand, borrowings under the current
facilities and from additional external financing.

The Company also has a loan outstanding with Corporacion Andina de Fomento (CAF)
of $11.8 million with interest based on LIBOR, and an outstanding loan from the
United States Export-Import Bank (EXIM)of $8.8 million, with interest at a 6.43%
fixed rate. Both loans are payable in semi-annual installments through 2001. At
December 31, 1999, the Company had outstanding borrowings of $222.5 million,
compared with $234.2 million at December 31, 1998.

Certain financing agreements contain covenants which limit the payment of
dividends to stockholders. Under the most restrictive covenant, the Company may
pay dividends to stockholders equal to 50% of the net income of the Company for
any fiscal quarter as long as such dividends are paid by June 30 of the
following year. Net assets of the Company unavailable for the payment of
dividends totaled $1.1 billion at December 31, 1999. In accordance with the most
restrictive covenant of the Company's loan agreements, additional indebtedness
of $903.4 million would have been permitted at December 31, 1999.

The Mitsui and Co., Ltd. credit agreement is collateralized by pledges of
receivables of 24,000 tons of copper per year. The EXIM Bank credit agreement is
collateralized by pledges of receivables from 7,000 tons of copper per year. The
CAF loan is collateralized by liens on the SX/EW facility. The SENS and the
seven year loan facility require that most of the collections of export copper
sales be deposited into a trust account in the United States. Twenty percent of
these collections are used as collateral for the outstanding SENS with the
balance of the collections remitted directly to the Company. The excess funds in
the collateral account are remitted to the Company, if all financial
requirements are

met. As part of these agreements, the Company must maintain three-month and
six-month collection ratios, as defined (aggregate collections as a specified
multiple of debt service). Both facilities require escrow deposits of three
months debt service. In addition, certain of the agreements require the Company
to maintain a minimum stockholders' equity of $750 million, specified ratios of
debt to equity, current assets to current liabilities and an interest coverage
test. Reduction of ASARCO Incorporated's (Asarco) voting interest in the Company
to less than a majority would constitute an event of default under two of the
financing agreements. The Company was in compliance with the various loan
covenants at December 31, 1999. Included in Other assets are $10.7 million held
in escrow accounts as required by the Company's loan agreements. The funds will
be released from escrow as scheduled loan repayments are made.

At December 31, 1999, the Company's debt as a percentage of total capitalization
(the total of debt, minority interest of investment shares and stockholders'
equity) was 16.3% as compared with 17.2% at December 31, 1998. At December 31,
1999, the Company's cash and marketable securities amounted to $10.6 million
compared with $198.1 million at December 31, 1998.

DIVIDENDS AND CAPITAL STOCK

The Company paid dividends to stockholders of $12.2 million, or $0.152 per
share, in 1999, $40.7 million, or $0.51 per share, in 1998 and $101.1 million,
or $1.26 per share in 1997. Distributions to the investment share minority
interest were $0.2 million, $0.9 million and $2.5 million in 1999, 1998 and
1997, respectively.

On February 25, 2000 a dividend of $0.06 a share, totaling $4.8 million was
declared, payable March 27, 2000. The Company's dividend policy will be reviewed
at the next Board of Directors meeting taking into consideration the current
intensive capital investment program, such as the expansion of mines,
concentrator/leach plant, smelter and future cash flow generated from
operations.

At the end of 1999 and 1998, the authorized and outstanding capital stock of the
Company consisted of 65,900,833 shares of Class A common stock, par value $0.01
per share; and 34,099,167 authorized shares of common stock, par value $0.01 per
share, of which 14,118,862 common shares were outstanding at December 31, 1999
and 13,949,812 shares were outstanding at December 31, 1998.

ENVIRONMENTAL MATTERS

The exploration, mining, milling, smelting and refining activities of the
Company are subject to Peruvian legislation and regulations. According to the
law, active mining companies submitted to the Ministry of Energy and Mines an
Environmental Compliance and Management Program (PAMA) that describes the
investments that the Company will make to comply with the maximum permissible
levels established for its operations by this Authority. The implementation of
the PAMA requires that the Company commit an annual minimum investment of 1% of
its sales. The Company's PAMA was approved in January 1997.

Under current Peruvian law and regulations, compliance with the PAMA will
satisfy environmental requirements pertaining to the Company's operations during
the applicable five-or-ten year implementation period. The Company remains,
however, subject to other environmental requirements applicable to its
operations.

The project with the PAMA that will demand the largest investment is the
modernization of the Ilo smelter. In a first phase the capture of sulfur dioxide
(SO2) will be increased from a current level of in excess of 30% to 67%. The
second phase of the project will further increase the capture of SO2 to in
excess of 92%, complying with current Peruvian environmental regulations.

<PAGE>
                                                                             A23


During the implementation of the project, Southern Peru continues to operate the
Supplementary Control Program (SCP), a voluntary effort, by which the smelter
production is restricted during periods of adverse meteorological conditions.
This program, in conjunction with the operation of the smelter's sulfuric acid
plant that was expanded to 317,500 tons per year, has contributed to effectively
improved air quality in Ilo.

In addition to the environmental programs for the Ilo smelter and the refinery,
the Company continues to have good results with the reclamation programs in both
Ite Bay and the beaches to the north of the smelter. Environmental capital
expenditures were $41.6 million in 1999, $25.3 million in 1998 and $47.8 million
in 1997. In addition, the Company estimates spending $50.0 million for
environmental control capital expenditures in 2000.

YEAR 2000

The Company completed a three phase program to identify and resolve Year 2000
(Y2K) issues related to the integrity and reliability of its computerized
information systems as well as computer systems embedded in its production
processes. As of December 31, 1999, the Company had spent approximately $1.3
million in addition to its normal internal information technology costs in
connection with its Y2K program. Through January 2000, the Company noted no loss
of production or disruptive events related to the Y2K issue.

IMPACT OF NEW ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS No.
133 "Accounting for Derivative Instruments and Hedging Activities". This
statement establishes accounting and reporting standards for derivative
instruments and hedging activities. Initially, the statement was to be effective
in fiscal years beginning after June 15, 1999. In June 1999, the FASB issued
SFAS No. 137 which defers the effective date of SFAS No. 133 one year until June
15, 2000. The Company is currently assessing the impact of SFAS No. 133.

CAUTIONARY STATEMENT

Forward-looking statements in this report and in other Company statements
include statements regarding expected commencement dates of mining or metal
production operations, projected quantities of future metal production,
anticipated production rates, operating efficiencies, costs and expenditures as
well as projected demand or supply for the Company's products. Actual results
could differ materially depending upon factors including the availability of
materials, equipment, required permits or approvals and financing, the
occurrence of unusual weather or operating conditions, lower than expected ore
grades, the failure of equipment or processes to operate in accordance with
specifications, labor relations, environmental risks as well as political and
economic risk associated with foreign operations. Results of operations are
directly affected by metals prices on commodity exchanges which can be volatile.

                        SOUTHERN PERU COPPER CORPORATION
                                and SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Principles of consolidation:

The consolidated financial statements of Southern Peru Copper Corporation and
Subsidiaries (the Company) include the accounts of significant subsidiaries in
which the Company has voting control, and are prepared in accordance with
generally accepted accounting principles in the United States (U.S. GAAP).
Certain prior year amounts have been reclassified to conform to the current year
presentation.

Use of estimates:

The preparation of financial statements in conformity with U.S. GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Revenue recognition:

Substantially all of the Company's copper is sold under annual contracts.
Revenue is recognized primarily in the month product is shipped to customers
based on prices as provided in sales contracts. When the price is not
determinable at the time of shipment to customers, revenue is recognized based
on prices prevailing at the time of shipment with final pricing generally
occurring within three months of shipment. Revenues with respect to these sales
are adjusted in the period of settlement to reflect final pricing and in periods
prior to settlement to reflect any decline in market prices, which may occur
between shipment and settlement. The Company sells copper in blister and refined
form at industry standard commercial terms. Net sales include the invoiced value
of copper, silver, molybdenum, acid, and gains from the sale or settlement of
copper put options.

Cash equivalents and marketable securities:

Cash equivalents include all highly liquid investments with a maturity of three
months or less, when purchased. Marketable securities include short-term liquid
investments with a maturity of more than three months, when purchased, and are
carried at cost, which approximates market.

Inventories:

Metal inventories are carried at the lower of average cost or market. Costs
incurred in the production of metal inventories exclude general and
administrative costs. Supplies inventories are carried at average cost less a
reserve for obsolescence.

Property:

Assets are valued at the lower of cost or net realizable value. In accordance
with SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of", the Company reviews long-lived assets and
certain identifiable intangibles related to those assets for impairment whenever
events or changes in circumstances indicate that the carrying amount of the
assets may not be recoverable. Any impairment loss on such assets, as well as
long-lived assets and certain identifiable intangibles to be disposed of, is
measured as the amount by which the carrying value of the assets exceeds the
fair value of the assets (less disposal costs, if applicable).

<PAGE>
                                                                             A29


The Company evaluates the carrying value of assets based on undiscounted future
cash flows considering expected metal prices based on historical metal prices
and price trends.

Betterments, renewals, costs of bringing new mineral properties into production,
and the cost of major development programs at existing mines are capitalized as
mineral land. Maintenance, repairs, normal development costs at existing mines,
and gains or losses on assets retired or sold are reflected in earnings as
incurred. Buildings and equipment are depreciated on the straight-line method
over estimated lives from 5 to 40 years or the estimated life of the mine if
shorter. Depletion of mineral land is computed by the units-of-production method
using proven and probable ore reserves.

Exploration:

Tangible and intangible costs incurred in the search for mineral properties are
charged against earnings when incurred.

Hedging Activities:

Derivative instruments may be used to manage exposure to market risk from
changes in commodity prices, interest rates or the value of the Company's assets
and liabilities. Derivative instruments, which are designated as hedges, must be
deemed effective at reducing the risk associated with the exposure being hedged
and must be designated as a hedge at the inception of the contract.

The Company may purchase put options or create synthetic put options to reduce
or eliminate the risk of metal price declines below the option strike price on a
portion of its anticipated future production. The cost of options is amortized
on a straight-line basis during the period in which the options are exercisable.
Gains or losses from the sale or exercise of options, net of unamortized
acquisition costs, are recognized in the period in which the underlying hedged
production is sold.

Swap Agreements:

Fuel swap agreements limit the effect of changes in the price of fuel. The
differential to be paid or received as fuel prices change is recorded as a
component of cost of sales in the period the swap covers.

Stock-Based Compensation:

The Company applies the disclosure only provisions of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation."

Impact of New Accounting Standards:

In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS No.
133 "Accounting for Derivative Instruments and Hedging Activities". This
statement establishes accounting and reporting standards for derivative
instruments and hedging activities. Initially, the statement was to be effective
in fiscal years beginning after June 15, 1999. In June 1999, the FASB issued
SFAS No. 137, which defers the effective date of SFAS No.133 one year until June
15, 2000. The Company is currently assessing the impact of SFAS No. 133.

2. Merger of Subsidiary Company

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 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.

3. Foreign Exchange

The functional currency of the Company is the U.S. dollar. The Company's sales,
cash, trade receivables, fixed asset additions, trade payables and debt are
primarily dollar-denominated. A portion of the operating costs of the Company is
denominated in Peruvian soles.

Gains and (losses) resulting from foreign currency transactions are included in
"Cost of sales" and amounted to ($2.5) million,($3.0) million, and $2.0 million
in 1999, 1998, and 1997, respectively.

4. Restructuring Charges

The Company's 1999 results include a $5.6 million pre-tax charge ($3.6 million
after-tax and workers' participation) for severance costs associated with the
Company's ongoing cost reduction program. The severance costs accrued are for
337 employees at the Company's locations in Peru and Miami, Florida.
Approximately $3.8 million of the provision is included as a cost of sales
deduction on the Company's statement of earnings, and $1.8 million is included
in administrative expense as it relates to non-operating personnel. This accrual
was paid in full as of December 31, 1999.

5. Administrative Reorganization

The Company's full year results include an $8.4 million pre-tax charge ($5.4
million after-tax and workers' participation) associated with the severance cost
of foreign contract employees' early termination. The severance costs accrued
are for 55 employees at the Company's locations in Peru. Approximately $5.8
million of the provision is included as cost of sales deduction on the Company's
statement of earnings, and $2.6 million is included in administrative expense as
it relates to non-operating personnel. Payments in the amount of $2.9 million
were made against this accrual in the year 1999.

6. Taxes on Income

The components of the provision for taxes on income are as follows:

At December 31, 1999, the foreign tax credit carryforward available to reduce
possible future U.S. income tax amounted to approximately $29.6 million expiring
as follows: $26.1 million in 2000, $3.1 million in 2003 and $0.4 million in
2004.

In 1997, the Government of Peru approved a reinvestment allowance for the
Company's program to expand the Cuajone mine. The reinvestment allowance
provides SPCC with tax incentives in Peru, and as a result, certain U.S. tax
credit carryforwards, for which no benefit had previously been recorded, were
realized. The reduction in the effective tax rate, as a result of the
reinvestment allowance for the twelve months ended December 31, 1997, lowered
tax expense approximately $14.7 million. Pursuant to the reinvestment allowance
SPCC has received tax deductions in Peru in amounts equal to the cost of the
qualifying property (approximately $245 million). The financial statement
carrying value of the qualifying property was reduced to reflect the tax benefit
associated with the reinvestment allowance (approximately $73 million). As a
result, financial statement depreciation expense related to the qualifying
property will be reduced over its useful life (approximately 15 years).

The Company has not recorded the benefit of foreign tax credit carryforwards
because of both the expiration dates and the rules governing the order in which
such credits are utilized. The Company also has not recorded a benefit

<PAGE>
                                                                             A32


for the AMT credits, which are not available to reduce AMT. Because of
limitations on both percentage depletion and foreign tax credits under the AMT,
the Company expects an AMT liability for the foreseeable future. Thus, while
such credits do not expire, it is unlikely they will be utilized. Accordingly, a
valuation allowance has been established for the full amount of the foreign tax
credit carryforward and the AMT credit carryforward.

The Company obtains income tax credits in Peru for value-added taxes paid in
connection with the purchase of capital equipment and other goods and services
employed in its operations and records these credits as a prepaid expense. Under
current Peruvian law, the Company is entitled to use the credits against its
Peruvian income tax liability or to receive a refund. The carrying value of
these Peruvian tax credits approximates their market value.

At December 31, 1999, the Company had no copper sales recorded at provisional
prices.

Under the terms of a sales contract with Union Miniere as amended through
December 31, 1999, the Company is required to supply Union Miniere, through its
agent, S.A. Sogem N.V., with 16,300 tons of blister copper annually for a ten
year period from January 1, 2000 through December 31, 2009. The price of the
copper, contained in blister, supplied under the contract is determined based on
the LME monthly average settlement price, less a refining allowance, which is
negotiated annually.

Under the terms of a sales contract with Mitsui & Co. Ltd. (Mitsui), the Company
is required to supply Mitsui with 48,000 tons of copper cathodes annually for a
fifteen-year period through December 31, 2013. Pricing of the cathodes is based
upon the LME monthly average settlement price plus a producer premium, which is
agreed upon annually based on world market terms. 90,000 tons related to a prior
contract (period 1994-2000) will be supplied as follows: 48,000 in 2014 and
42,000 in 2015.

8. Financial Instruments

Hedging Activities: The Company uses derivative instruments to manage its
exposure to market risk from changes in commodity prices. Derivative instruments
which are designated as hedges must be deemed effective at reducing the risk
associated with the exposure being hedged and must be designated as a hedge at
the inception of the contract.

Copper: Depending on the market fundamentals and other conditions, the Company
may purchase put options to reduce or eliminate the risk of price declines below
the option strike price on a portion of its anticipated future production. Put
options purchased by the Company establish a minimum sales price for the
production covered by such put options and permit the Company to participate in
price increases above the option price. The cost of options is

<PAGE>
                                                                             A33


amortized on a straight-line basis during the period in which the options are
exercisable. Depending upon market conditions, the Company may either sell
options it holds or exercise the options at maturity. Gains or losses from the
sale or exercise of options, net of unamortized acquisition costs, are
recognized in the period in which the underlying production is sold and are
reported as a component of the underlying transaction. Earnings include pre-tax
gains from option sales and exercises of $7.2 million in 1998 and $10.2 million
in 1997. At December 31, 1999, the Company held no copper put options.

Fuel Swaps: The Company may enter into fuel swap agreements to limit the effect
of increases in fuel prices on its production costs. A fuel swap establishes a
fixed price for the quantity of fuel covered by the agreement. The difference
between the published price for fuel and the price established in the contract
for the month covered by the swap is recognized in production costs. As of
December 31, 1999 and 1998, the Company has entered into the following fuel swap
agreements:

The unrealized gain in the Company's fuel swap positions at December 31, 1999
was $8.7 million. The effect of a hypothetical 10 percent decrease from December
31, 1999 fuel prices would be to reduce the unrealized gain on fuel swaps by
$3.7 million.

In 1999, the Company's production cost would have been $10.7 million higher if
this exposure had not been hedged.

Foreign currency: The Company selectively uses foreign currency swaps to limit
the effects of exchange rate changes on future cash flow obligations denominated
in foreign currencies. A currency swap establishes a fixed dollar cost for a
fixed amount of foreign currency required at a future date. The Company has
entered into currency swap agreements on a portion of its capital cost
contracted in Euros.

As of December 31, 1999 the Company had the following currency swap agreements:

The unrealized loss in the Company's currency swap position at December 31, 1999
was $3.3 million. A hypothetical 10 percent decrease from December 31, 1999
rates, would increase the unrealized loss of currency swaps by $2.9 million. The
full cost of the currency swap amounts as acquired will, when exercised, be
included in the cost of the capital asset for which these swaps were obtained.

For certain of the Company's financial instruments, including cash and cash
equivalents, marketable securities, accounts receivables and accounts payable
the carrying amounts approximate fair value due to their short maturities.
Consequently, such financial instruments are not included in the following table
that provides information about the carrying amounts and estimated fair values
of other financial instruments:

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate that
value:

Fuel swap agreements - Fair value is based on quoted market prices.

Currency swap agreements: Fair value is based on quoted market prices.

Long-term debt - Fair value is based on the quoted market prices for the same or
similar issues.

9. Workers' Participation

Provisions for workers' participation are calculated at 8% of pre-tax earnings
and are included in "Cost of sales" on the earnings statement. The current
portion of this participation, which is accrued during the year, is based on
Branch taxable income and is distributed to workers following determination of
final results for the year.

10. Minority Interest of Investment Shares (Previously known as "Labor Shares")

The minority interest of the Investment Shares is based on the earnings of the
Company's Peruvian Branch.

The Company acquired 0.8 million, 1.0 million and 2.0 million investment shares
at a cost of $3.4 million, $3.8 million and $8.9 million in the years 1999, 1998
and 1997, respectively. The carrying value of the minority interest purchased
was reduced by $2.1 million, $2.5 million and $5.1 million in 1999, 1998 and
1997, respectively, and the excess paid over the carrying value was assigned
primarily to proven and probable sulfide and leachable ore reserves and
mineralized material and is being amortized based on production. As a result of
these acquisitions, the remaining investment shareholders hold a 1.7% interest
in the Branch at December 31, 1999, and are entitled to a pro rata participation
in the cash distributions made by the Branch. The investment shares are recorded
as a minority interest in the Company's financial statements.

In March 1999, the Company concluded a $100 million 15-year loan agreement with
Mitsui and Co., Ltd. The applicable interest for this loan is the LIBO rate plus
1.25%. This facility provides additional committed financing for SPCC's
modernization and expansion program. A commitment fee of 0.5% per annum is
payable on the undrawn portion of this loan through December 31, 2001. As of
December 31, 1999, $2.0 million had been drawn from this loan facility.

In 1997, the Company entered into a $600 million seven-year credit agreement
with a group of international financial institutions. The agreement consists of
a $400 million term loan facility and a $200 million revolving credit facility.
The interest rate during the first three years of the agreement on any loans
outstanding is LIBOR plus 1.75% per annum for term loans and LIBOR plus 2.0% for
revolving credit loans. A commitment fee of 0.5% per annum is payable on the
undrawn portion of the facility. No amounts have been drawn under this agreement
as of December 31, 1999.

Also in 1997, the Company privately placed $150 million of SENS in the United
States and international markets. These notes, which have been registered with
the Securities and Exchange Commission, begin amortizing in 2000 and mature in
2007 and were priced at par with a coupon rate of 7.9%. In addition, in June
1997 the Company sold $50 million of 8.25% bonds due June 2004 to investors in
Peru.

Some financing agreements contain covenants, which limit the payment of
dividends to stockholders. Under the most restrictive covenant, the Company may
pay dividends to stockholders equal to 50% of its net income for any fiscal
quarter as long as such dividends are paid by June 30 of the following year. As
a result, net assets of the Company unavailable for the payment of dividends
totaled $1.1 billion at December 31, 1999. In accordance with the most
restrictive covenant of the Company's loan agreements, additional indebtedness
of $903.4 million would have been permitted at December 31, 1999.

The Mitsui and Co., Ltd. credit agreement is collateralized by pledges of
receivables of 24,000 tons of copper per year. The EXIM Bank credit agreement is
collateralized by pledges of receivables from sales of 7,000 tons of copper per
year. The CAF loan is collateralized by liens on the SX/EW facility. The SENS
and the seven-year loan facility require that most of the collections of export
copper sales be deposited into a trust account in the United States. Twenty
percent of these collections are used as collateral for the outstanding SENS
with the balance of the collections remitted directly to the Company.

The excess funds in the collateral account are remitted to the Company, if all
financial requirements are met. As part of these agreements, the Company must
maintain three-month and six month collection ratios, as defined (aggregate
collections as a specified multiple of debt service). Both facilities require
escrow deposits of three months debt service. In addition, certain of the
agreements require the Company to maintain a minimum stockholders' equity of
$750 million, specified ratios of debt to equity, current assets to current
liabilities and an interest coverage test. Reduction of ASARCO Incorporated's
(Asarco) voting interest in the Company to less than a majority would

constitute an event of default under two of the financing agreements. The
Company was in compliance with the various loan covenants at December 31, 1999.
Included in Other assets are $10.7 million held in escrow accounts as required
by the Company's loan agreements. The funds will be released from escrow as
scheduled loan repayments are made.

15. Benefit Plans

The Company has a noncontributory, defined benefit pension plan covering
salaried employees in the United States and certain employees in Peru. Benefits
are based on salary and years of service. The Company's funding policy is to
contribute amounts to the plans sufficient to meet the minimum funding
requirements set forth in the Employee Retirement Income Security Act of 1974,
plus such additional amounts as the Company may determine to be appropriate.
Plan assets are invested in commingled stock and bond funds.

The components of net periodic benefit costs are as follows:

Post-retirement Benefits:

The post-retirement health care plan for retired salaried employees eligible for
Medicare was adopted by the Company on May 1, 1996. Secondary coverage under the
Company's plan is available for all retired salaried employees who permanently
reside in the United States and who contribute amounts as defined by the plan.
The plan is unfunded.

The components of net periodic benefit costs are as follows:

The annual assumed rate of increase in the per capita cost of covered benefits
(i.e., health care cost trend rate) is assumed to be 5%. The health care cost
trend rate assumption has a significant effect on the amounts reported. For
example, increasing the assumed health care cost trend rates by one percentage
point would increase the accumulated postretirement benefit obligation costs

periodic postretirement benefit would have an insignificant change. Decreasing
the assumed health care cost trend rates by one percentage point in each year
would decrease the accumulated postretirement benefit obligation for 1999 by
$0.1 million and the service and interest cost components of net periodic
postretirement benefit costs would have an insignificant change.

Employee Savings Plan:

The Company maintains an employee savings plan for employees working in the
United States and expatriate employees in Peru which permits employees to make
contributions by payroll deduction pursuant to section 401(k) of the Internal
Revenue Code. The plan provides for a Company matching contribution equal to 50%
of the first 6% of employee contributions. In connection with the required
match, the Company's contributions charged against earnings were $0.1 million,
$0.2 million and $0.2 million in the years 1999, 1998 and 1997, respectively.

Class A common shares are entitled to five votes per share. Common shares are

Stock Options:

The Company has two stockholder approved plans, a Stock Incentive Plan and a
Directors' Stock Award Plan. The Stock Incentive Plan provides for the granting
of nonqualified or incentive stock options, as defined under the Internal
Revenue Code of 1986, as amended, as well as for the award of restricted stock
and bonuses payable in stock. The price at which options may be granted under
the Stock Incentive Plan shall not be less than 100% of the fair market value of
the common stock on the date of grant in the case of incentive stock options, or
50% in the case of other options. In general, options are not exercisable for
six months and expire after 10 years from the date of grant.

Options granted may provide for Stock Appreciation Rights (SAR). An SAR permits
an optionee, in lieu of exercising the option, to receive from the Company
payment of an amount equal to the difference between the market value of the
stock on the date of election of the SAR and the purchase price of the stock
under the terms of the option.

The authorized number of shares under the Stock Incentive Plan is 1,000,000 of
which 300,000 may be awarded as restricted stock. At December 31, 1999, 645,060
shares are available for future grants under this plan (737,610 shares at
December 31, 1998). The weighted average remaining contractual life of stock
option's outstanding as of December 31, 1999 was 7.1 years.

The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation". Accordingly, no compensation cost has
been recognized for awards under the stock incentive plan. If compensation cost
for the Company's Stock Incentive Plan had been determined based on the fair
value at the grant date for awards in 1999, 1998 and 1997, consistent with the
provisions of SFAS No. 123, the Company's net earnings and earnings per share
would have been reduced to the proforma amounts indicated below:

The fair value of each option grant was estimated on the date of grant using the
Black-Scholes option-pricing model with the following assumptions used for
grants in 1999: dividend yield of 7.9%(4.8%-1998, 4.05%-1997); expected
volatility of 48.0% (40.4%-1998, 29.2%-1997); risk-free interest rate of 4.8%
(5.6%-1998, 6.3%-1997); and expected life of 7.1 years (7.1 years-1998, 7.0
years-1997).

The Company purchases shipping services from a company indirectly controlled by
Quemchi S.A. of which the Vice Chairman is also director of SPCC. The total cost
of these services amounted to $8.3 million, $11.5 million and $13.3 million in
1999, 1998 and 1997, respectively.

18. Concentration of Risk

The Company operates two copper mines, a smelter and two refineries in Peru and
substantially all of its assets are located there. There can be no assurances
that the Company's operations and assets that are subject to the jurisdiction of
the Government of Peru may not be adversely affected by future actions of such
government. Substantially all of the Company's products are exported from Peru
to customers principally in Europe, Asia, South America and the United States.

Financial instruments, which potentially subject the Company to a concentration
of credit risk, consist primarily of cash and cash equivalents, marketable
securities and trade accounts receivable.

The Company invests or maintains available cash with various high-quality banks,
principally in the U.S., Canada and Peru, or in commercial paper of highly rated
companies. As part of its cash management process, the Company regularly
monitors the relative credit standing of these institutions, and by policy,
limits the amount of credit exposure to any one institution. At December 31,
1999, the Company had no investments of its cash equivalents and marketable
securities with Peruvian banks.

During the normal course of business, the Company provides credit to its
customers. Although the receivables resulting from these transactions are not
collateralized, the Company has not experienced significant problems with the
collection of receivables.

The largest ten trade receivable balances accounted for 68.3% of the trade
accounts receivable at December 31, 1999, of which one customer represented
18.6%.

19. Commitments and Contingencies

In September 1996, the Company announced a two-stage project which includes an
expansion of the Cuajone mine and an expansion and modernization of the copper
smelter at Ilo.

The Cuajone mine expansion, which consists of an expansion in annual copper
production by 130 million pounds at an estimated capital investment of $245
million, was completed at December 31, 1999. Additional mining equipment will be
received next year.

The second stage of the program, the expansion and modernization of the Ilo
smelter is expected to be completed by the year 2006. Early in January 2000 the
Company announced that technologies currently being evaluated would allow
achievement of the smelter improvements at significantly less than the $875
million budgeted for the project. If such modifications to the original plan are
made, the smelter will still meet government standards when the modernization
program is completed, despite the capital savings. This evaluation should be
completed in the second quarter of 2000.

In 1998, the Company commenced a $48 million project to expand annual SX/EW
copper production by 26 million pounds. The project was completed in the third
quarter of 1999.

As a result of the expansion program, electric power requirements will increase
significantly, requiring the construction of substantial additional generating
capacity. In 1997, the Company sold its existing power plant to an independent
power company for $33.6 million. In connection with the sale, a power purchase
agreement was also completed, under which the Company agreed to purchase its
power needs for the next twenty years.

Environmental:

The exploration, mining, milling, smelting and refining activities of the
Company are subject to Peruvian legislation and regulations. According to the
law, active mining companies submitted to the Ministry of Energy and Mines an
Environmental Compliance and Management Program (PAMA) that describes the
investments that Company will make to comply with the maximum permissible levels
established for its operations by this Authority. The implementation of the PAMA
requires that the Company commit an annual minimum investment of 1% of its
sales. The Company's PAMA was approved in January 1997.

Under current Peruvian law and regulations, compliance with the PAMA will
satisfy environmental requirements pertaining to the Company's operations during
the applicable five-or-ten year implementation period. The Company remains,
however, subject to other environmental requirements applicable to its
operations.

The project with the PAMA that will demand the largest investment is the
modernization of the Ilo smelter. In the first phase, the capture of sulfur
dioxide (SO2) will be increased from a current level of in excess of 30% to 67%.
The second phase of the project will further increase the capture of SO2 to in
excess of 92%, complying with current Peruvian environmental regulations.

During the implementation of the project, Southern Peru continues to operate the
Supplementary Control Program (SCP), a voluntary effort, by which the smelter
production is restricted during periods of adverse meteorological conditions.
This program, in conjunction with the operation of the smelter's sulfuric acid
plant that was expanded to 317,500 tons per year, has contributed to improve air
quality in Ilo.

In addition to the environmental programs for the Ilo smelter and the refinery,
the Company continues to have good results with the reclamation programs in both
Ite Bay and the beaches to the north of the smelter. Environmental capital
expenditures were $41.6 million in 1999, $25.3 million in 1998 and $43.8 million
in 1997. In addition, the Company estimates spending $50.0 million for
environmental control capital expenditures in 2000.

Litigation:

In April 1996, the Company was served with a complaint filed in Peru by
approximately 800 former employees seeking the delivery of a substantial number
of investment shares (formerly called "labor shares") of its Peruvian Branch
plus dividends. In October 1997, the Superior Court of Lima nullified a decision
of a court of first instance, which had been adverse to the Company. The
Superior Court remanded the case for a new trial. Plaintiff filed an
extraordinary appeal before the Peruvian Supreme Court. The Supreme Court may
grant discretionary review in limited cases. In March 1999, the Company received
official notification that the Superior Court had denied plaintiff's
extraordinary appeal and affirmed the decision of the Supreme Court of Lima
which remanded the case to the lower court for further proceedings. In December
1999, the lower court decided against the Company, ordering the delivery of the
investment shares and dividends to the plaintiffs. The Company appealed this
decision in January 2000. There is also pending against the Company a similar
lawsuit filed by 127 additional former employees. In the third quarter of 1997,
the court of first instance dismissed their complaint. Upon appeal filed by the
plaintiffs, the Superior Court of Lima, in the third quarter of 1998, nullified
the lower court's decision on technical ground and remanded the case to the
lower court for further proceedings. In December 1999, the lower court dismissed
the complaint against the Company. Plaintiffs appealed this decision in January
2000.

It is the opinion of management that the outcome of the legal proceedings
mentioned, as well as other miscellaneous litigation and proceedings now
pending, will not materially adversely affect the financial position of the
Company and its consolidated subsidiaries. However, it is possible that
litigation matters could have a material effect on quarterly or annual operating
results, when they are resolved in future periods.

                        Report of Independent Accountants

To the Board of Directors and Stockholders
of Southern Peru Copper Corporation

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of earnings, cash flows and changes in stockholders'
equity present fairly, in all material respects, the financial position of
Southern Peru Copper Corporation and its subsidiaries (the "Company") at
December 31, 1999 and 1998, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1999, in
conformity with accounting principles generally accepted in the United States.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

Metal Price Sensitivity

Assuming that expected metal production and sales are achieved, that tax rates
are unchanged, that the number of shares outstanding is unchanged, and giving no
effect to hedging programs or changes in the costs of production, metal price
sensitivity factors would indicate the following estimated change in earnings
per share resulting from metal price changes in 2000. Estimates are based on
80.0 million shares outstanding.

Item 9. Changes In and Disagreements with Accountants on Accounting and
Financial Disclosure

On February 25, 2000, the Board of Directors of the Company selected Arthur
Andersen L.L.P. to serve as independent accountants for the Company for the
calendar year 2000, and resolved to submit this selection to the approval of the

Eligible Employee's elections, but will not be required to do so. Regardless of
whether the Eligible Employee's elections are followed, the Deferral Amount
shall be credited with deemed earnings, gains, losses, expenses, and changes in
the fair market value of such Deferral Amount as if SPCC had followed such
investment designations. All elections and amendments to elections shall be in
accordance with rules, if any, as shall be established by the Committee.

(b) The election of a deemed investment option is the sole responsibility of
each Eligible Employee. Neither SPCC, nor the Committee that administers the
Plan, nor any trustee of any trust that may be established in connection with
the Plan are authorized or permitted to advise (or shall have any liability with
respect to) an Eligible Employee as to the election of any option or the manner
in which his Deferral Amount shall be deemed to be invested.

SECTION 8.    VALUE OF BENEFITS.

The amount of the lump sum referred to in Section 5(a) shall be the present
value of the Benefit amount determined under Section 4 (after taking into
account, if applicable, any reductions as set forth in the Pension Plan to
reflect the commencement of payments prior to age 65) by assuming that the
Eligible Employee has elected a single life annuity under the Pension Plan and
by using the following actuarial assumptions:

(a) DISCOUNT RATE. The discount rate used in computing the present value of
benefits payable under the Plan is the yield on 10-year treasury notes on the
Eligible Employee's Benefit Commencement Date, or if a legal holiday, the first
business day immediately following the Benefit Commencement Date. At any time
during a thirteen month period ending with the Benefit Commencement Date, an
Eligible Employee may designate an alternative date for fixing the interest rate
(the Alternative Date) used to calculate the value of the lump sum distribution.
The designation must be in writing, and the Alternative Date must be within 7
calendar days of the date the designation is received by the Company. The
designation of the Alternative Date for fixing the interest rate, once made, may
not be changed for any reason. Notwithstanding the foregoing, if an Eligible
Employee designates an Alternative Date under this subsection in contemplation
of commencing benefits under the Pension Plan, such designation will survive a
subsequent postponement of the commencement of benefits under the Pension Plan
by such Eligible Employee, except that, if the yield on 10-year treasury notes
on the Benefit Commencement Date is higher than on the Alternative Date, the
yield on the Benefit Commencement Date will be used.


<PAGE>


(b) MORTALITY TABLE. The Mortality Table used will be that contained in U.S.
Internal Revenue Service Revenue Ruling 95-6 or any succeeding Revenue Ruling
issued by the Internal Revenue Service for use in applying the provisions of
Sections 415 and 417(e) of the Internal Revenue Code.

SECTION 9.    EMPLOYEE'S RIGHTS UNSECURED.

The right of any Eligible Employee to receive benefits under the provisions of
the Plan shall be contractual in nature only; however, the amounts of such
benefits may be held in a trust, the assets of which shall be subject to the
claims of the Company's general creditors in the event of bankruptcy or
insolvency only. Any amounts paid from such trust shall reduce the amount of
benefits owed by the Company.

SECTION 10.   SEVERABILITY.

The provisions of this Plan shall be severable, and if any one or more
provisions shall be considered or held to be invalid or unenforceable, or shall
result in a portion of the Plan being treated as a pension plan under Title I of
ERISA, the remaining provisions shall continue to be valid and enforceable.

SECTION 11.   PARTICIPATION IN OTHER PLANS.

Nothing in this Plan will affect any right which an Eligible Employee may
otherwise have to participate in any other retirement plan, or agreement, which
the Company may have now or hereafter.

SECTION 12.   DISCRETION OF COMPANY AND BOARD.

Any decision made or action taken by the Company or by the Board arising out of
or in connection with the construction, administration, interpretation, and
effect of the Plan shall lie within the absolute discretion of the Company or
the Board, as the case may be, and shall be final, conclusive and binding upon
all persons.

SECTION 13.   ASSIGNMENT.

No right or interest of the Eligible Employee under this Plan shall be subject
to voluntary or involuntary alienation, assignment or transfer of any kind.

SECTION 14.   COST TO BE BORNE BY SUBSIDIARY.

If any payment under this Plan is to be made to an Eligible Employee on account
of any employee's service for a subsidiary of the Company, the cost of such
payment shall be borne in such proportions as the Company and such subsidiary
shall determine.

SECTION 15.   AMENDMENT.

This Plan may at any time or from time to time be amended, modified,
discontinued or terminated by the Board if, in its sole discretion, such a
change is deemed necessary and desirable.


<PAGE>


SECTION 16.   GOVERNING LAW.

This Agreement shall be governed by and construed in accordance with the laws of
the State of New York.

         IN WITNESS WHEREOF, the Company has caused this Amendment to its
Supplemental Retirement Plan to be duly adopted and executed by its duly
authorized officers and its corporate seal affixed hereto as of November 4,
1999.

written election to defer either 50 percent or 100 percent of cash compensation
payable by reason of service on the Board. An amount equal to the compensation
deferred will be credited to the Participant's Participant Account as soon as
practicable after the date such compensation is otherwise payable.

         An election to participate must be received by the Company prior to
January 1 of the calendar year during which the election is to be effective and
shall be irrevocable for the entire year. Notwithstanding the foregoing, a
Director may elect to become a Participant in the Plan for the calendar year in
which he first becomes eligible by filing a written election to participate
within 30 days of becoming eligible. The election will be effective on a
prospective basis and only as to remuneration not yet earned.

         An election shall remain in effect for subsequent years unless amended
or terminated in writing prior to January 1 of any subsequent year. An election
can be revoked or withdrawn at any time with respect to amounts to be earned in
years subsequent to the date of revocation or withdrawal.

SECTION 5.    DEEMED INVESTMENT PROVISIONS.  The Company will establish a
Participant Account for each Participant. Each Participant Account will have an
SPCC Stock Subaccount and/or an Investment Subaccount. A Participant must
allocate his Deferral Amounts, in increments of 25 percent, to one or both of
the Subaccounts.

(a)      DEFERRAL AMOUNTS ALLOCATED TO SPCC STOCK SUBACCOUNTS

         1)   A Participant's SPCC Stock Subaccount shall be deemed invested in
              accordance with the Participant's election in whole shares of
              Company common stock which could be purchased at Fair Market Value
              with the Deferral Amounts credited to a Participant's SPCC Stock
              Subaccount on the last business day of each calendar quarter.

         2)   The Stock Subaccount also shall be credited with a bookkeeping
              entry indicating the number of additional whole shares which could
              be purchased at Fair Market Value with any dividends payable on
              the deemed shares held in the SPCC Stock Subaccount on the day
              such dividends are payable to shareholders of Company common
              stock.

         3)   Any amounts that are insufficient to permit the crediting of a
              whole share of Company common stock shall be carried as a cash
              balance bookkeeping entry in such Stock Subaccount. On any date on
              which new funds are available for deemed investment in Company
              stock (either due to an additional deferral or the availability of
              deemed dividends), the cash amount will be added to any such other
              funds, and the maximum number of whole shares that could be
              purchased at Fair Market Value will be deemed invested. The
              remaining amount, if any, will be held as cash. No interest shall
              be credited on any such Stock Subaccount cash balance.


<PAGE>


         4)   The SPCC Stock Subaccount shall be adjusted to reflect any stock
              split, stock dividend, recapitalization, merger, consolidation,
              reorganization or other similar change in the Company's common
              stock.

(b)      DEFERRAL AMOUNTS ALLOCATED TO INVESTMENT SUBACCOUNTS

         A Participant's Deferral Amounts will be credited to his Investment
         Subaccount except to the extent he has elected in writing to credit his
         Deferral Amounts to his Stock Subaccount. Each Investment Subaccount
         will be credited with interest from the date on which deferred
         compensation would normally have been paid, until payment, at a rate
         equal to the yield rate for U.S. Treasury debt obligations with a
         10-year maturity effective for the last business day in each quarter,
         on the first day of each calendar quarter in which such interest is
         credited to the Participant's Investment Subaccount. Interest will be
         compounded quarterly.

SECTION 6.    TRANSFERS. No election may be made to have amounts previously
credited to a Participant's Investment Subaccount transferred to his Stock
Subaccount. Amounts previously credited to a Participant's Stock Subaccount may
not be transferred to his Investment Subaccount, except on or after the earlier
in time of (a) one year prior to Normal Retirement Date, or (b) the date of
termination.

SECTION 7.    PAYMENT OF DEFERRED COMPENSATION.
(a)      RETIREMENT AT NORMAL RETIREMENT DATE
         A Participant who retires at or following his Normal Retirement Date
         will receive the entire value of his Participant Account in cash on
         January 15 of the year following the year of retirement.

(b)      TERMINATION AT OTHER THAN NORMAL RETIREMENT DATE
         A Participant who terminates service as a Director at a date prior to
         his Normal Retirement Date will receive the entire value of his
         Participant Account in cash promptly following the date of termination.

(c)      FURTHER DEFERRAL
         Notwithstanding (a) and (b)of this section, a Participant may elect to
         further defer receipt of all or a portion of his Participant Account
         for a period of up to 10 years from the earlier in time of the Deemed
         Retirement Date or the date of termination. In order to defer a payment
         of benefits under the Plan, a Participant must file a written election
         at least one year in advance of the date that a payment of benefits
         under the Plan would otherwise be made. The Participant may elect to
         receive the amount deferred in a single cash payment or in annual cash
         installments. Any further elections to defer the receipt of benefits
         under the Plan must also be filed at least one year prior to the
         scheduled payment date. Acceleration of any benefits deferred pursuant
         to this paragraph can only be made by filing a request for payment at
         least one year in advance of the requested accelerated payment date.


<PAGE>


(d)      FINANCIAL HARDSHIP OF PARTICIPANTS
         At any time a Participant may request a payment of all or a portion of
         the value of his Participant Account. Such a request shall be approved
         by the Company only upon a finding that the Participant has suffered a
         severe financial hardship which has resulted from events beyond the
         Participant's control ("Hardship Event"), and only in the amount
         reasonably needed to satisfy such Hardship Event. Whether a Hardship
         Event has occurred shall be determined in accordance with Treasury
         Regulation Sections 1.457- 2(h)(4) and (5). In the event such a payment
         is approved, payment of all or a portion of the value of the
         Participant Account shall be made as soon as practicable to the
         Participant.

(e)      OTHER WITHDRAWALS

         Absent a Hardship Event or adequate prior notice (in accordance with
         paragraph (c) above), a request for a payment of all or a portion of
         the value of a Participant Account may be made by a Participant subject
         to a 6% penalty of the amount of the requested payment, which penalty
         shall be deducted from the requested payment. The requested payment,
         less such penalty, shall be paid in cash in a single lump sum as soon
         as practicable after the requested payment date.

SECTION 8.    DESIGNATION OF BENEFICIARY.

(a)      A Participant may designate a beneficiary by giving written notice to
         the Company. If no beneficiary is designated, the beneficiary will be
         the Participant's estate. If more than one beneficiary statement has
         been filed, the beneficiary or beneficiaries designated in the
         statement bearing the most recent date will be deemed the valid
         beneficiary.

(b)      In the event of a Participant's death before he has received all of the
         benefits to which he is entitled hereunder, the value of the
         Participant's Participant Account shall be paid to the estate or
         designated beneficiary of the deceased Participant in one cash lump sum
         as soon as practicable after the first January 15 or July 15 following
         such date of death, unless the Participant has elected to continue
         without change the schedule for payment of benefits, in which case the
         beneficiary shall have the right to transfer amounts previously
         credited to a Participant's Stock Subaccount to his Investment
         Subaccount.

(c)      If a distribution is to be made to a beneficiary and such beneficiary
         dies before such distribution has been made, the amount of the
         distribution will be paid to the estate of the beneficiary in one lump
         sum.

SECTION 9.    PARTICIPANT'S RIGHTS UNSECURED. The right of any Participant to
receive benefits under the provisions of the Plan shall be contractual in nature
only; however, the amounts of such benefits may be held in a trust, the assets
of which shall be subject to the claims of the Company's general creditors only
in the event of bankruptcy or insolvency. Any amounts paid to a Participant from
such trust shall reduce the amount of benefits owed by the Company.


<PAGE>


SECTION 10.   ASSIGNABILITY. No right to receive payments hereunder shall be
transferable or assignable by a Participant or beneficiary.

SECTION 11.   PARTICIPATION IN OTHER PLANS. Nothing in this Plan will affect any
right which a Participant may otherwise have to participate in any other
retirement plan or agreement which the Company may have now or hereafter.

SECTION 12.   DISCRETION OF COMPANY AND BOARD. Any decision made or action taken
by the Company or by the Board arising out of or in connection with the
construction, administration, interpretation and effect of the Plan shall lie
within the absolute discretion of the Company or the Board, as the case may be,
and shall be final, conclusive and binding upon all persons.

SECTION 13.   AMENDMENT. This Plan may at any time or from time to time be
amended, modified or terminated by the Board. No amendment, modification or
termination shall, without the consent of a Participant, adversely affect such
Participant's accruals in his Participant Account.

SECTION 14.   GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.

    Employee".

SECTION 4 - PARTICIPATION.
a)  ELECTION TO DEFER

1)  SALARY DEFERRAL. To become a Participant in the salary deferral component of
    the Plan for a particular calendar year, an Eligible Employee must elect,
    prior to the beginning of such calendar year, to defer receipt of a
    percentage of his base annual salary to be earned during the succeeding
    calendar year. Such an election shall be in writing on forms prescribed by
    the Committee, and shall include the percentage of base annual salary to be
    deferred. A Participant's election to defer with respect to a calendar year
    under this subsection (a)(1) shall continue in effect for all subsequent
    calendar years until changed in accordance with subsection (d). An employee
    of the Company who becomes an Eligible Employee during a calendar year may

    for such calendar year by electing to defer a percentage of his base annual
    salary (in accordance with Section 4(b)) within 30 days of becoming an

<PAGE>


b)  DEFERRAL AMOUNT

1)  SALARY DEFERRAL. A Participant who meets the requirements of Section 4(a)(1)
    for a calendar year may elect to have the following amounts (the "Salary
    Deferral Amount") credited to his account for such calendar year or portion
    thereof during which an election is effective (the "Deferral Period"):

         a)  the product of (i) the Participant's elected salary deferral
    contribution percentage under this Plan (not to exceed the maximum
    contribution percentage permitted under the Savings Plan) and (ii) the
    lesser of the Participant's base annual salary for such year or the
    Compensation Limit (as defined below); reduced by the maximum contribution
    permitted for highly compensated employees under the Savings Plan due to
    the limitations imposed by Code Section 401(k)(3) or by the plan
    administrator for the Savings Plan for such calendar year; and

         b)  the Participant's elected salary deferral contribution percentage
    under the Savings Plan as in effect on January 1 of such year, multiplied
    by the Participant's base annual salary in excess of the Code
    Section 401(a)(17) limit, as adjusted from time to time ($160,000 in 1999)
    (the "Compensation Limit"); provided, however, that the total amount of
    Salary Deferrals under this subsection cannot exceed the maximum
    contribution percentage as may then be permitted under the Savings Plan).

2)  INCENTIVE COMPENSATION DEFERRAL. The amount of a Participant's incentive
    compensation deferral for a Deferral Period shall be any whole dollar amount
    or whole percent of his Incentive Compensation Award payable during the
    calendar year as elected by the Participant (the "Incentive Compensation
    Deferral Amount"). In the event the award payable is less than the dollar
    amount specified in the Participant's election, the full amount of the award
    shall be deferred (subject to Section 15).

3)  EMPLOYER PROVIDED BENEFIT. With respect to each Deferral Period, the Company
    shall make a deemed matching contribution equal to 50% of each Participant's
    Salary Deferral Amount (each such deemed matching contribution, an "Employer
    Provided Benefit); provided, however, that no Participant's Employer
    Provided Benefit with respect to a particular year may exceed the amount by
    which 3% of such Participant's base salary for such year exceeds the
    matching contribution made by the Company on the Participant's behalf under
    the Savings Plan for such year.

4)  SPECIAL INCENTIVE AWARDS. Notwithstanding anything to the contrary herein,
    the Committee, in its discretion, may provide for any amounts awarded to a
    Participant by the Board or the Committee as a special incentive award under
    the Incentive Compensation Plan to be deferred pursuant to the terms of this
    Plan and credited to a Participant's Account, subject to the terms and
    limitations of the award ("Special Incentive Awards").

c)  IRREVOCABILITY OF ELECTION


<PAGE>


    Subject to the provisions of subsection (d) of this Section 4, a deferral
election hereunder shall be irrevocable.

a)  At the time of the election to participate in the Plan, the Participant must
    elect in writing to have his Deferral Amounts deemed invested, in increments
    of no less than 5%, in one or more of the investment funds as are provided
    under the Savings Plan, except; however, that the SPCC Common Stock Fund
    shall not be available as a deemed investment. Said election must total one
    hundred percent (100%) of his Deferral Amounts.

b)  The Participant Accounts shall be credited with deemed earnings, gains,
    losses, expenses and changes in the fair market value of such Participant
    Accounts as if the Company had followed such investment designations.

c)  Each Participant may elect in writing that his future Deferral Amounts be
    deemed invested in a proportion different from that previously elected, but
    the new election shall be prospective only and shall be made in accordance
    with paragraph (b) of this Section 5. Any changes in such deemed investments
    must be in accordance with rules, if any, as are established by the
    Committee.

d)  The election of a deemed investment option is the sole responsibility of
    each Participant. Neither the Company, nor the Committee, nor any trustee of
    any trust that may be established in connection with the Plan are authorized
    or permitted to advise (or shall have any liability with respect to) a
    Participant as to the election of any option or the manner in which his
    Deferral Amounts shall be deemed to be invested.

e)   Consistent with this Section 5, each Participant may elect in writing, that
     a whole percentage (no less than 5%) or specific dollar amount of his
     deemed investment in any fund may be transferred to any other fund
     available under the Plan. Such election will be prospective only and will
     be permitted in accordance with rules, if any, as are established by the
     Committee.

SECTION 6  -  PAYMENT OF BENEFITS.

Each Participant shall receive the value of his Participant Account in cash
promptly following the Participant's Retirement or other termination from the
Company. In the event of the death of a Participant before receiving the value
of his Participant Account, such distribution shall be paid to his beneficiary
or beneficiaries designated pursuant to Section 7 as soon as practicable under
the Plan.

SECTION 7  -  DESIGNATION OF BENEFICIARY.

A Participant may designate one or more beneficiaries by giving written notice
to the Committee. If no beneficiary is so designated, the Participant's
beneficiary will be the Participant's estate. If more than one beneficiary
statement has been filed the beneficiary or beneficiaries designated in the
statement bearing the most recent date will be deemed the valid beneficiary.

SECTION 8  -  PARTICIPANT'S RIGHTS UNSECURED.

The right of any Participant to receive benefits under the provisions of the
Plan shall be contractual in nature only; however, the amounts of such benefits
may be held in a trust, the assets of which shall be subject to the claims of
the Company's general creditors only in the event of bankruptcy or insolvency.
Any amounts paid to a Participant from such trust shall reduce the amount of
benefits owed by the Company.

SECTION 9  -  PARTICIPATION IN OTHER PLANS.

Nothing in this Plan will affect any right which a Participant may otherwise
have to participate in any other retirement plan or agreement which the Company
may have now or hereafter.

SECTION 10  - NON-ALIENATION OF BENEFITS.

No right to receive payments hereunder shall be transferable or assignable by a
Participant or beneficiary.

SECTION 11  - ADMINISTRATION OF THE PLAN.

The Plan shall be administered by the Committee. The Committee shall construe
and interpret the Plan and may adopt rules and regulations governing the
administration of the Plan, as well as exercise any duties and powers conferred
on it by the terms of the Plan. The Committee shall act by vote or written
consent of a majority of its members or otherwise as in accordance with its
general procedures as in effect from time to time.

SECTION 12  - AMENDMENT OR TERMINATION OF THE PLAN.

This Plan may at any time or from time to time be amended, modified or
terminated by the Board. No amendment, modification or termination shall,
without the consent of a Participant, adversely affect such Participant's
accruals in his Participant Account.


<PAGE>


SECTION 13  - NO ENTITLEMENT TO AWARDS OR RIGHT OF CONTINUED EMPLOYMENT.

Neither the establishment of the Plan nor the payment of any benefits hereunder
nor any action of the Company, a subsidiary of the Company, or the Committee
shall be held or construed to confer upon any person any legal right to be
awarded any amounts under the Incentive Plan or the Incentive Compensation Plan
or to continue in the employ of the Company or a subsidiary of the Company. The
Company and its subsidiaries expressly reserve the right to discharge any
Participant whenever the interest of any such company in its sole discretion may
so require without liability to such company or the Committee except as to any
rights which may be expressly conferred upon such Participant under the Plan.

SECTION 14  - DISCRETION OF COMPANY, COMMITTEE, AND BOARD.

Any decision made or action taken by the Company or by the Committee or by the
Board arising out of or in connection with the construction, administration,
interpretation and effect of the Plan shall lie within the absolute discretion
of the Company, the Committee or the Board, as the case may be, and shall be
final, conclusive and binding upon all persons.

SECTION 15  - TAX WITHHOLDING.

There shall be deducted from all deferrals or payments made under this Plan the
amount of any taxes required to be withheld by any Federal, state, local or
foreign government, including any employment taxes required to be withheld under
Code Section 3121(v). The Participants and their beneficiaries, distributees,
and personal representatives will bear any and all Federal, foreign, state,
local or other income or other taxes imposed on amounts paid under the Plan, and
the Company may take whatever actions are necessary and proper to satisfy all
obligations of such persons for payment of all such taxes.

SECTION 17  - SEVERABILITY.

In the event any provision of this Plan would serve to invalidate the Plan, that
provision shall be deemed to be null and void, and the Plan shall be construed
as if it did not contain the particular provision that would make it invalid.

SECTION 18  - GOVERNING LAW; BINDING EFFECT; MISCELLANEOUS.

The Plan shall be governed and construed and enforceable in accordance with the
laws of the State of New York, except as superseded by applicable Federal law.

Where appearing in the Plan, the masculine gender shall include the feminine
gender.

         IN WITNESS WHEREOF, the Company has caused the Southern Peru Copper
Corporation Compensation Deferral Plan to be duly adopted and executed by its
duly authorized officers and its corporate seal affixed hereon as of November 4,
1999.
