B43 Report of Independent Accountants ------------------- To the Participants and Administrative Committee of the Savings Plan of Southern Peru Copper Corporation and Participating Subsidiaries In our opinion, the accompanying statements of net assets available for benefits, with fund information and the related statements of changes in net assets available for benefits, with fund information present fairly, in all material respects, the net assets available for benefits of Savings Plan of Southern Peru Copper Corporation and Participating Subsidiaries (the "Plan") at December 31, 1998 and December 31, 1997 and the changes in net assets available for benefits for the year ended December 31, 1998 and the seven months ended December 31, 1997 in conformity with generally accepted accounting principles. These financial statements are the responsibility of the Plan'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 generally accepted auditing standards 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. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of Assets Held for Investment Purposes and Reportable Transactions are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The fund information in the statements of net assets available for benefits and the statement of changes in net assets available for benefits is presented for purposes of additional analysis rather than to present the net assets available for plan benefits and changes in net assets available for benefits of each fund. These supplemental schedules and fund information are the responsibility of the Plan's management. The supplemental schedules and fund information have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

B48 Savings Plan of Southern Peru Copper Corporation And Participating Subsidiaries Notes to Financial Statements 1. Plan Description The following description of the Savings Plan of Southern Peru Copper Corporation and Participating Subsidiaries (the "Plan") provides only general information. Reference should be made to the Plan document for a complete description of the Plan and Plan amendments, including eligibility requirements and vesting provisions. General: Effective June 1, 1985, Southern Peru Copper Corporation (the "Company") established the Plan, which has been amended thereafter. The Plan is a defined contribution plan and is administered by the Administrative Committee in accordance with authority delegated by the Board of Directors. The Plan is designed to provide a method of savings by eligible employees for their retirement and other needs. Contributions: An employee becomes eligible to participate in the Plan after the completion of 30 days service. Each eligible employee wishing to participate in the Plan must elect to authorize pre-tax and/or post-tax contributions (the "contributions") by payroll deduction. Contributions are stated in whole percentages of 1% to 12% of the participant's earnings, as defined, or a specified dollar amount. A participant may elect to increase, decrease or suspend the contributions on the first day of any month. The Internal Revenue Code of 1986 (the "Code"), as amended, limited the maximum amount an employee may contribute on a pre-tax basis to $10,000 and $9,500 in 1998 and 1997, respectively. Participants are 100% vested in their contributions and earnings therein. Matching Company Contribution - Effective January 1, 1998, the Company matches the first 6% of a participant's monthly contribution at a rate of 50%. The matching contribution may be made in cash or Company common stock. Company contributions for the year ended December 31, 1998 consisted of cash in the amount of $167,144. The Company is not obligated to make a contribution during any period in which it has no accumulated retained earnings. The Company's contributions are subject to all legal restrictions, which may apply, including Sections 401 and 415 of the Code, which limit the annual contributions to an employee's account. Loans: The Plan provides for loans to participants who have participated in the Plan for at least one year, subject to certain limitations. The maximum loan allowed to each participant is limited to the lesser of 50% of the total value of the participant's account or $50,000 reduced by the highest outstanding plan loan balance to such participant during the prior twelve-month period ending on the day before the date the loan is made. B49 Notes to Financial Statements - Continued A participant's loan is repayable within a maximum of five years or immediately upon termination of employment, if sooner. Interest is currently accrued at the prime rate, which was in existence on the first day of the month in which the loan was issued. Loans are collateralized by a lien on the participant's interest in the Plan. Loan repayments are made through payroll withholdings from the participant's earnings. A participant may pre-pay a loan at any time without penalty. 2. Significant Plan Amendments On May 1, 1997, the Plan was amended, effective January 1, 1998, to appoint the Vanguard Fiduciary Trust Company (Vanguard) as the Trustee, Investment Manager and Recordkeeper of the Plan, modify the Plan year end to be December 31, permit employees to contribute on an after-tax basis, include non-U.S. expatriates as eligible employees, require the Company matching contribution to be invested in the newly created Southern Peru Copper Corporation Common Stock Fund and change the definition of compensation used for purposes of contributions to include only base salary. On November 4, 1997, the Plan was further amended, effective January 1, 1998, to change the eligibility waiting period from six months of service to 30 days of service and permit plan entry on the first day of any month, permit only one loan at a time, include a one year participation eligibility requirement for purposes of initiating a loan, provide for the transferability of the Company matching contributions for participants who attain age 64, remove existing hardship withdrawal provisions and permit in-service withdrawals subject to certain suspension penalties, revise the provisions relating to distribution upon termination of employment to grandfather the Joint and Survivor Annuity Option and frequency of installment payments for participants with account balances as of December 31, 1997, require the immediate distribution of account balances under $5,000, permit participants with account balances in excess of $5,000 to elect a distribution at any time prior to age 65 and provide for the payment of administrative expenses by the Company with the exception of expenses pertaining to loan administration, which shall be charged to participants with outstanding loan balances. The Plan was also amended to be in accordance with the Small Business Job Protection Act of 1996. In addition, effective January 1, 1998, the Plan name was amended from the Southern Peru Copper Corporation 401(k) Savings Plan to the Savings Plan of Southern Peru Copper Corporation and Participating Subsidiaries. 3. Summary of Significant Accounting Policies Investment Valuation: The Plan's investments are stated at fair value. Units of registered investment companies are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. The Southern Peru Common Stock Fund is valued at its year-end closing price (comprised of year-end market price plus uninvested cash position). Participant loans are valued at cost which approximates fair value. Basis of Accounting: The financial statements of the Plan are prepared under the accrual method of accounting. B50 Notes to Financial Statements - Continued Investment Transactions and Investment Income: Transactions are accounted for on a trade-date basis. Average cost is the basis used in the determination of gains or losses on sales of securities. Dividend income is recorded on the ex-dividend (stockholder date of record) date. Interest income from participant loans is recorded as earned. Capital gain distributions are included in dividend income. Net appreciation (depreciation) in the fair value of the Plan's investments, as shown in the Statement of Changes in Net Assets Available for Benefits, consists of realized gains or losses and the change in unrealized appreciation (depreciation) on those investments. Investment funds with balances less than five percent of the total net assets of the Plan, as of December 31, 1998 and 1997 and similar investment objectives have been aggregated on the Statements of Net Assets Available for Benefits and the Statement of Changes in Net Assets Available for Benefits. Payment of Benefits: Benefits are recorded when paid. Plan Expenses: The Company pays all administrative expenses of the Plan. The Company also pays the fees of consultants, auditors and counsel, and transfer taxes on shares of Southern Peru Copper Corporation Common Stock distributed to Plan participants or their beneficiaries, with the exception of loan administrative fees, which are charged to participants. Investment fees related to Vanguard funds and all other taxes, brokerage commissions and any other expenses directly relating to the investment of the Trust Fund are paid from assets of the plan. Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of investment income and deductions during the reporting period. Actual results could differ from those estimates. Risks and Uncertainties: The Plan provides for investment options in various mutual funds. Investment securities are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the Statement of Net Assets Available for Benefits and the Statement of Changes in Net Assets Available for Benefits. Participants are advised to read a Vanguard prospectus or the Plan's summary plan description before investing in any fund. B51 Notes to Financial Statements - Continued 4.

B54 Notes to Financial Statements - Continued 5. Related Party Transactions The Plan invests in shares of mutual funds managed by an affiliate of Vanguard. Vanguard acts as trustee for only those investments as defined by the Plan. Transactions in such investments qualify as party-in-interest transactions, which are exempt from the prohibited transaction rules. 6. Tax Status The Plan, as amended through August 13, 1990, received a favorable determination letter from the Internal Revenue Service ("IRS") that it is a qualified plan and trust under Section 401(a) of the Code and, thus, exempt from federal income taxes under provisions of Section 501(a) of the Code. The Plan has been amended since receiving the determination letter. However, the Plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the code. 7. Termination Priorities Although it has not expressed any intent to do so, the Company reserves the right to amend or discontinue the Plan by action of the Board at any time. In the event of termination or partial termination of the Plan, participants will receive the fair value of their account as of the date of such termination or partial termination.
