NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

A. In the opinion of Southern Peru Copper Corporation (the “Company” or “SPCC”), the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the Company’s financial position as of September 30, 2002 and the results of operations and cash flows for the three and nine months ended September 30, 2002 and 2001. Certain reclassifications have been made in the financial statements from amounts previously reported. The results of operations for the three and nine-month periods are not necessarily indicative of the results to be expected for the full year. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2001 annual report on Form 10-K.

B. Inventories were as follows:

(In millions)

	September 30, 2002		December 31, 2001
Metals at lower of average cost or market:
Finished goods	$	3.3	$	1.8
Work-in-process	42.7		45.9
Supplies at average cost, net of reserves	48.0		53.3
Total inventories	$	94.0	$	101.0

C. At September 30, 2002, the Company has recorded sales of 9.4 million pounds of copper, at an average provisional price of $0.65 per pound. Also the Company has recorded sales of 1.3 million pounds of molybdenum at an average provisional price of $4.36 per pound. These sales are subject to final pricing based on the average monthly LME and COMEX copper prices and dealer oxide molybdenum prices in the month of settlement, which will occur in the fourth quarter of 2002.

D. In the first quarter 2002, the Company changed the estimated lives of certain machinery and equipment. This change was accounted for prospectively and resulted in a reduction to depreciation expense of approximately $9.4 million in the first nine months of 2002.

E. Related Party Transactions:

As of September 30, 2002, the Company had overdue receivables of $2.2 million from Minera Mexico International Inc. (“MMI”) and $4.9 million from Americas Sales Corp. (“ASC”), related to sales of copper, at market prices and with customary terms to MMI and ASC, $2.2 million in 2001 and $4.9 million in 2002, respectively. MMI and ASC are subsidiaries of Grupo Mexico, the majority (54.2%) indirect stockholders of the Company. As of October 17, 2002, the Company collected $0.7 million from MMI reducing the balance to $1.5 million. The Company believes ASC and MMI intend and have the ability to pay the amounts due.

F. Purchase of Investment Shares:

In July 2002, the Company acquired 2.1 million investment shares for $8.2 million in cash. The acquisition of the investment shares has been accounted for as the purchase of a minority interest. The excess purchase price over the cost of the share of $6.2 million has been allocated to proven and probable copper resources. As a result of the transaction, the interest of investment shareholders in the Branch was reduced from 1.4% to 0.8%.

G. Commitments and Contingencies:

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 December 1999, the civil court of first instance of Lima decided against the Company, ordering the delivery of the investment shares and dividends to the plaintiffs. The Company appealed this decision in January 2000. On October 10, 2000, the Superior Court of Lima affirmed the lower court’s decision, which had been adverse to the Company. On appeal by the Company, the Peruvian Supreme Court annulled the proceeding noting that the civil courts lacked jurisdiction and that the matter had to be decided by a labor court. The case is now pending before a labor court of first instance in Lima.

There was also pending against the Company a similar lawsuit filed by 127 additional former employees. In December 1999, the civil court of first instance of Lima dismissed the complaint against the Company. Plaintiffs appealed this decision in January 2000 before the Superior Court. By the end of 2000, the Superior Court rejected the appeal. Plaintiffs filed an extraordinary appeal before the Supreme Court. In July 2002, the Company was notified that the Supreme Court of Peru had affirmed the decision of the lower court dismissing the case. Therefore, the case has been resolved favorably for the Company.

In February 2002, the Company received notice that approximately 3,000 additional former employees intended to file a similar lawsuit, for unspecified amounts, seeking the delivery of a substantial number of investment shares. The conciliation hearing took place and was concluded when no agreement was reached. In August 2002, the Company was notified that these former workers had filed a lawsuit before the labor court in Lima. The labor court rejected the complaint due to procedural defects. The plaintiffs appealed this decision before the Superior Court of Lima.

On December 28, 2000, a lawsuit styled Flores v Southern Peru Copper Corporation was filed against the Company in federal court in New York City. The Flores lawsuit sought unspecified compensatory and punitive damages for alleged personal injuries to eight persons resident in Peru arising from alleged releases into the environment from the Company’s operations in Peru. The lawsuit invoked the jurisdiction of the court under the federal Alien Tort Claims Act, claiming violations of customary international law. The Flores lawsuit is similar to a suit filed in 1995 in Texas, for unspecified amounts, which was dismissed in 1996 by a U. S. district judge. That ruling was affirmed unanimously by a three-judge federal appeals court. The court made it clear that the claims of Peruvian residents should be tried in the courts of Peru, not in the United States. On July 16, 2002, the United States District Court for the Southern District of New York dismissed the complaint in the Flores lawsuit. In its decision, the district court ruled that it lacked jurisdiction under the Alien Tort Claims Act because the Peruvian plaintiffs had failed to allege a cognizable claim that international law had been violated. In the alternative, the district court stated that, even if it had jurisdiction, it nonetheless would dismiss the Flores lawsuit on the basis of the doctrine of forum non convenient, because the dispute should be litigated in the courts of Peru, not in the United States. On August 28, 2002, the Flores plaintiffs filed a notice of appeal to seek review of the district court decision by the United States Court of Appeals for the Second Judicial Circuit. No briefing schedule has yet been established for the appeal.

Income Taxes - United States:

The Internal Revenue Service (“IRS”) has completed the fieldwork phase of their audit of the Company for the years 1994 through 1996. In September 2002, the IRS issued a Notice of Proposed Adjustment, which among other things challenged the Company’s method of valuation of leach dumps. The Company will file a protest with the Appeals Office of the IRS and will vigorously defend its position. The Company believes that in all material respects the positions taken in reporting to the IRS are correct and appropriate.

Income Taxes - Peru:

The Company received assessments from SUNAT (the Peruvian tax department) for years 1996 to 1999, in which several deductions taken were disallowed. SUNAT has challenged the Company’s depreciation methods, the deduction of certain interest expense and other expenses related to charges incurred outside of Peru. The Company has appealed these assessments. The assessments for years 1996 and 1997 are currently being contested in the Peruvian Tax Court. The assessment for years 1998 and 1999 are presently being contested by the Company before SUNAT. The Company believes that in all material respects the positions taken in reporting to SUNAT are correct and appropriate.

It is the opinion of management that the outcome of the legal proceedings and tax contingencies above 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 the tax contingencies and litigation matters could have a material effect on quarterly or annual operating results, when they are resolved in future periods.

H. Impact of New Accounting Standards:

In August 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 143 “Accounting for Asset Retirement Obligations”, which will be required to be adopted effective January 1, 2003. SFAS No. 143 establishes standards for accounting for an obligation associated with the retirement of long-lived tangible assets. Management is assessing the impact of this statement on the results of operations and financial condition.

In April 2002, the FASB issued SFAS No. 145 to rescind FASB Statement No. 4, “Reporting Gains and Losses from Extinguishment of Debt”, and an amendment of that Statement, FASB Statement No. 64, “Extinguishments of Debt Made to Satisfy Sinking-Fund Requirements”. This statement also rescinds FASB Statement No. 44, “Accounting for Intangible Assets of Motor Carriers”. This statement, which shall be applied in fiscal years beginning after May 15, 2002, amends FASB Statement No. 13, “Accounting for Leases”, to eliminate an inconsistency between the required accounting for sale-leaseback transactions and the required accounting for certain lease modifications that have economic effects that are similar to sale-leaseback transactions. This statement also amends other existing authoritative pronouncements to make various technical corrections, clarify meanings, or describe their applicability under changed conditions. Management is assessing the impact of this statement on the results of operations and financial condition.

In June 2002, the FASB issued SFAS No. 146 Accounting for Costs Associated with “Exit or Disposal Activities”, which will be required to be effective for exit or disposal activities that are initiated after December 31, 2002. This statement addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)”. Management is assessing the impact of this statement on the results of operations and financial condition.

Part I

Items 2 and 3.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

AND QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company reported net earnings of $14.4 million, or 18 cents per basic and diluted share, for the third quarter ended September 30, 2002, compared with net earnings of $11.6 million, or 15 cents per basic and diluted share, for the third quarter of 2001. For the first nine months of 2002, net earnings were $45.8 million or 57 cents per basic and diluted share, compared to $34.7 million or 43 cents per basic and diluted share, for the same period of 2001. Sales of products were $169.9 million in the third quarter of 2002, compared with $171.5 million in the third quarter of 2001. Sales of products for the first nine months of 2002, totaled $499.4 million, compared with $496.8 million for the same period of the previous year.

The increase in earnings in the third quarter of 2002 is primarily due to higher molybdenum prices and decreased financing expenses, as debt levels were significantly lower in the third quarter of 2002, offset somewhat, by lower copper sales. The average price for copper on the London Metal Exchange (LME) and the New York Commodity Exchange (COMEX), was 69 cents per pound for the third quarter of 2002 compared with 67 cents per pound in the third quarter of 2001. The average price for copper in the nine month period ended September 30, 2002 was three cents lower than the comparable 2001 period. The average price for molybdenum, one of SPCC’s principal by-products, was higher in the third quarter of 2002 at $4.71 per pound, compared with $2.41 for the same period of 2001. In the first nine months of 2002 the average price for molybdenum was $3.94 per pound, compared with $2.37 for the same period of 2001.

Mine copper production increased 0.4% to 192.2 million pounds in the third quarter of 2002, compared with the third quarter of last year. This increase of 0.7 million pounds included a decrease of 5.2 million pounds from the Toquepala mine, an increase of 6.8 million pounds from the Cuajone mine, and a decrease of 0.9 million pounds in solvent extraction/electrowinning (SX/EW) production. The Toquepala mine decrease in production was due to lower ore grades. The increase in production at the Cuajone mine was due to higher ore grades mined and better copper recovery at the concentrator. The main reason for the 0.9 million pounds decrease in SX/EW production was lower grades of PLS (Pregnant Leaching Solution).

The Toquepala concentrator expansion and modernization project was completed at the end of August 2002, with a total investment of $69.5 million. With the completion of this project, the Toquepala concentrator milling capacity has increased from 45,000 to 60,000 metric tons per day. The increase in production represents a significant step towards reducing unit costs and optimizing the break-even point of SPCC’s copper production. The Cuajone leaching facilities expansion project was developed to expand the leaching facilities pads and the crushing plant. This will allow the plant to increase the production of copper in PLS from 13.5 tons to 18 tons per day of copper contained in solution for treatment at the solvent extraction plant in Toquepala.

The Company announced on October 30, 2002, that union workers at the Company’s Toquepala mine in Tacna, Peru, began a strike principally as a result of a dispute over work day schedules at the mine. Workers were seeking to alter the current duration of work day shifts and the current number of days worked consecutively.

On November 10, 2002, the strike ended as Company management and the union reached an accord. Agreement was reached on matters related to arbitrary retirement issues. Work schedules questions will continue to be discussed by Company and union representatives.

The Company estimates that lost production due to this strike is 7,800 metric tons of copper concentrates, 100 metric tons of molybdenum concentrates, 23,400 ounces of silver and 50 ounces of gold.

Inflation and Devaluation of Peruvian Nuevo Sol: The functional currency of the Peruvian Branch is the US Dollar. A portion of the Company’s operating costs is denominated in Peruvian nuevos 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 Peruvian nuevo sol, the financial position, results of operations and cash flows of the Company could be adversely affected.

For the three months ended September 30, 2002, the inflation and devaluation rates were 0.61% and 3.79%, respectively, compared with 0.00% and (0.85%) in the comparable 2001 period. For the nine months ended September 30, 2002, the inflation and devaluation rates were 1.23% and 5.75%, respectively, and for the nine months periods ended September 30, 2001 the inflation and devaluation rates were 0.42% and (1.22%), respectively.

Net Sales: Net sales in the third quarter of 2002 decreased $1.6 million to $169.9 million from the comparable period in 2001. Net sales for the first nine months of 2002 totaled $499.4 million, compared with $496.8 million for the same period of 2001. The decrease in net sales in the three-month period ended September 30, 2002 was principally a result of the decrease in copper sales volume of 20 million pounds, offset by significantly higher molybdenum prices and a slightly higher copper price. Net sales in the nine month period ended September 30, 2002 increased slightly from the year earlier period due to higher molybdenum prices in 2002, offset somewhat by the impact of lower copper prices in the period.

At September 30, 2002, the Company has recorded sales of 9.4 million pounds of copper, at an average provisional price of $0.65 per pound. Also the Company has recorded sales of 1.3 million pounds of molybdenum at an average provisional price of $4.36 per pound. These sales are subject to final pricing based on the average monthly LME and COMEX copper prices and dealer oxide molybdenum prices in the month of settlement, which will occur in the fourth quarter of 2002.

Prices: Sales prices for the Company’s metals are established principally by reference to prices quoted on the LME, the COMEX or as published in Platt’s Metals Week for dealer oxide mean prices for molybdenum products.

Metal Price Sensitivity: There is market risk arising from the volatility of copper prices. Assuming that expected metal production and sales are achieved, that tax rates are unchanged, that the number of shares outstanding is unchanged, and disregarding the effects of hedging programs or changes in past production, metal price sensitivity factors would indicate the following estimated change in earnings per share resulting from metal price changes in 2002. Estimates are based on 80.0 million shares outstanding.

Operating Costs and Expenses: Operating costs and expenses were $144.0 million in the third quarter of 2002, compared with $151.6 million in the third quarter of 2001. In the nine months ended September 30, 2002 operating costs and expenses were $409.8 million, compared with $428.5 million in the comparable 2001 period.

Cost of sales for the three months ended September 30, 2002 was $117.6 million compared with $125.4 million in the comparable 2001 period. The decrease in the third quarter was principally a result of lower copper sales volume. In the nine months ended September 30, 2002 cost of sales was $332.6 million, compared with $343.7 million in the comparable 2001 period, the decrease of $11.1 in the nine months of 2002, includes a lower cost of Company mined copper, this decrease was partially offset by the higher cost of copper processed and sold from purchased concentrates.

Administrative and other expenses were $6.6 million in the three months ended September 30, 2002 and $7.1 million in the comparable 2001 period. In the nine months ended September 30, 2002, administrative and other expenses were $21.5 million compared with $22.9 million in the nine months ended September 30, 2001. The decrease in the third quarter 2002 and the nine months ended September 30, 2002, compared with the same periods of 2001, is mainly due to a decrease in legal and consulting services and other expenses.

Depreciation and depletion expense for the three months ended September 30, 2002 was $16.8 million, compared with $16.6 million in the comparable 2001 period. In the nine months ended September 30, 2002 depreciation and depletion expense was $49.3 million, compared with $56.2 million in the comparable 2001 period. The decrease in the first nine months of 2002 is principally due to a change related to longer estimated service lives of assets implemented during the first quarter of 2002.

Non-Operating Items: Interest income was $0.7 million in the third quarter of 2002, compared with $4.9 million in the comparable 2001 period. In the nine months ended September 30, 2002 interest income was $2.0 million, compared with $14.1 million for the same period of 2001. The decrease reflects lower amounts of excess cash invested in 2002.

Interest expense was $2.9 million in the third quarter of 2002, compared with $11.4 million in the third quarter of 2001. In the nine months ended September 30, 2002, interest expense was $10.2 million, compared with $31.8 million in the first nine months of 2001. The decrease reflects the lower level of long-term debt of the Company during 2002, as compared to the same periods during 2001, and lower interest rates.

Taxes on Income: Tax on income for the three months ended September 30, 2002 were $9.2 million, compared with $4.1 million for the same period of 2001. Taxes on income for the nine months ended September 30, 2002 were $24.0 million (net of a $3.9 million benefit, which was recorded as part of the extraordinary loss), compared with $16.6 million for the same period of 2001. The increase in the third quarter and the nine months ended September 30, 2002, was principally due to higher earnings in 2002.

Cash Flows:

Third Quarter: Net cash provided by operating activities was $51.3 million in the third quarter of 2002, compared with $19.6 million in the comparable 2001 period. The increase was principally attributable to increased contributions from operating assets and liabilities.

Net cash used in investing activities was $27.0 million related to capital expenditures. In the third quarter of 2001, net cash used in investing activities was $44.3 million related to capital expenditures.

Net cash used for financing activities in the third quarter of 2002 was $18.6 million, compared with $38.5 million for the third quarter of 2001. The third quarter of 2002 includes a dividend distribution of $10.2 million, while the third quarter of 2001 included a dividend distribution of $3.7 million. In the third quarter of 2001 the Company had debt payments of $37.7 million and received $3.0 million from released escrow deposits. In the third quarter of 2002 the Company acquired a significant block of outstanding investment shares at a cost of $8.3 million, reducing the investment shareholders’ interest in the Branch from 1.4% to 0.8%.

Nine Months: Net cash provided by operating activities was $141.9 million for the nine-month period ended September 30, 2002, compared with $160.6 million in the comparable 2001 period. The decrease was attributable primarily to reimbursements of Peruvian value added taxes of $45.5 million in 2001.

Net cash used in investing activities was $105.6 million in the nine-month period ended September 30, 2002, as compared with $112.0 in the comparable 2001 period. These funds in both periods were used primarily in the Company’s expansion and modernization projects.

Cash used for financing activities for the nine months ended September 30, 2002 was $124.7 million, compared with net cash inflows of $261.8 million in the comparable 2001 period. The nine months ended September 30, 2002, include proceeds of $25.9 million from bonds issued in the first quarter and 6.9 million released from escrow deposits. In addition, the Company prepaid the outstanding balance of its secured Exports Notes of $134.3 million, including a premium of $11.4 million; the Company also paid cash dividends to stockholders of $14.4 million and acquired investment shares at a cost of $8.6 million. The nine months ended September 30, 2001, include proceeds of $400.0 million under a credit line contracted with a group of international financial institutions, which was prepaid in December 2001. In addition, debt repayment of $85.0 million, an escrow deposit of $29.1 million and dividend distributions of $23.0 million were made in the nine months ended September 30, 2001.

Liquidity and Capital Resources: In the third quarter of 2002, the Company declared a dividend to shareholders of $12.5 million or 15.6 cents per share, compared with $3.7 million or 4.7 cents per share in the same period of 2001. On October 22, 2002, the Company declared a quarterly dividend of 8.9 cents per share payable November 27, 2002, to stockholders of record at the close of business on November 12, 2002.

Certain financing agreements contain covenants that limit the payment of dividends to stockholders. Under the most restrictive covenant, the Company may pay dividends to stockholders up to 50% of the net income of the Company, on an annual basis.

The Company expects to meet its liquidity and capital expenditure requirements, from internally generated funds, cash on hand and from additional external financing.

Critical Accounting Policies and Estimates:

Southern Peru Copper Corporation’s discussion and analysis of its financial condition and results of operations, as well as quantitative and qualitative disclosures about market risks, are based upon its consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States of America (“US GAAP”). Preparation of these financial statements requires Southern Peru’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the reported amounts of revenues and expenses, for the reported period. The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates and units-of-production for mine depletion determination; environmental, reclamation and closure obligations; asset impairments (including estimates of future cash flow); and litigation and contingencies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Southern Peru, at least annually, estimates its ore reserves at active properties and properties currently on care-and-maintenance status. Ore reserve estimates are based upon engineering evaluations of assay values derived from samplings of drill holes and other openings. Additionally, declines in the market price of a particular metal may render certain reserves containing relatively lower grades of mineralization economically unfeasible to mine. Further, availability of permits, changes in operating and capital costs, and other factors could materially and adversely affect ore reserves. Southern Peru uses its ore reserve estimates in determining the unit basis for mine depreciation, as well as in evaluating mine assets impairments. Changes in ore reserve estimates could significantly affect these items. Please also refer to “Cautionary Statement”.

During the first quarter of 2002, the Company changed the estimated useful lives of certain machinery and equipment. This change was accounted for prospectively and resulted in a reduction to depreciation expense of approximately $9.4 million in the first nine months of 2002. Estimated useful lives of the Company’s fixed assets are based on periodic evaluation by the Company’s management and engineers. Changes in such estimates could significantly affect, among other things, the Company’s operating costs and net income.

Impact of New Accounting Standards:

In August 2001, the FASB issued SFAS No. 143 “Accounting for Asset Retirement Obligation”, which will be required to be adopted effective January 1, 2003. SFAS No. 143 establishes standards for accounting for an obligation associated with the retirement of long-lived tangible assets. Management is assessing the impact of this statement on the results of operations and financial condition.

In June 2002, the FASB issued SFAS No. 146 “Accounting for Costs Associated with Exit or Disposal Activities”, which will be required to be effective for exit or disposal activities that are initiated after December 31, 2002. This statement addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)”. Management is assessing the impact of this statement on the results of operations and financial condition.

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 metal prices on commodity exchanges, which can be volatile.

Item 4. Controls and Procedures

As of September 30, 2002, the Company carried out an evaluation, under the supervision and with the participation of the Company’s Disclosure Committee and the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Company (including its consolidated subsidiaries) required to be included in the Company’s periodic SEC filings. Subsequent to the date of that evaluation, there have been no significant changes in the Company’s internal controls or in other factors that could significantly affect internal controls, nor were any corrective actions required with regard to significant deficiencies and material weaknesses.
