Information reported in the Original Filing remains in effect except to the extent that it is amended, restated or superseded by information contained in this Amendment No. 1. Capitalized terms used and not defined in this Amendment No. 1 have the meanings set forth in the Original Filing. ITEM 1. SECURITY AND ISSUER Item 1 of the Original Filing is hereby amended and restated in its entirety as follows: The statement relates to the Common Stock, par value $0.01 per share (the "Common Stock") of Southern Peru Copper Corporation, a Delaware corporation ("the Company"). The Company's principal executive offices are at 2575 East Camelback Rd., Phoenix, AZ 85016. ITEM 2. IDENTITY AND BACKGROUND. Item 2 of the Original Filing is hereby amended and restated in its entirety as follows: This statement is being filed on behalf of Phelps Dodge Overseas Capital Corporation, a Delaware corporation ("Phelps Dodge Overseas"), Climax Molybdenum B.V., a Dutch corporation ("Climax"), and Phelps Dodge Corporation, a New York corporation ("PDC"). Phelps Dodge Overseas and Climax are wholly-owned subsidiaries of PDC. The principal business of Phelps Dodge Overseas is to hold stock in SPCC. The principal business of Climax is to process molybdenum. The principal business of PDC is mining and manufacturing. The address of the principal business and office of Phelps Dodge Overseas and PDC is One North Central Avenue, Phoenix, Arizona 85004. The address of the principal business and office of Climax is P.O. Box 1130, 3180 AC Rozenburg, Theemsweg 20, 3197 KM Botlek, Rotterdam, The Netherlands. The name, business address, present principal occupation or employment, and citizenship of each director and executive officer of Phelps Dodge Overseas is set forth on Schedule A attached hereto. The name, business address, present principal occupation or employment, and citizenship of each director and managing director of Climax is set forth on Schedule B attached hereto. The name, business address, present principal occupation or employment, and citizenship of each director and executive officer of PDC is set forth on Schedule C attached hereto. During the past five years, neither Phelps Dodge Overseas, Climax nor PDC nor any other person controlling either Phelps Dodge Overseas, Climax or PDC, nor, to the best knowledge of Phelps Dodge Overseas, Climax or PDC, any of the persons listed on Schedules A, B and C attached hereto, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to any civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violations with respect to such laws. 6 ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION Item 3 of the Original Filing is hereby amended and supplemented by adding the following: On December 17, 2004, Phelps Dodge Overseas transferred 2,210,000 shares of Class A Common Stock of the Company to PDC as a dividend. Through a series of capital contributions and an inter-company purchase in exchange for a note, the 2,210,000 shares of Class A Common Stock of the Company were subsequently transferred to Climax on December 22, 2004. As a result of these transactions, Phelps Dodge Overseas currently holds 8,963,796 Shares of the Class A Common Stock of the Company, and Climax holds 2,210,000 Shares of the Class A Common Stock of the Company. ITEM 4. PURPOSE OF TRANSACTION Item 4 of the Original Filing is hereby amended and restated in its entirety as follows: The Exchange Offer was conducted to (i) provide holders of Labor Shares with an opportunity to receive securities of the Company which are listed on both the New York Stock Exchange and the Lima Stock Exchange, (ii) establish public trading markets in the United States and Peru for the Company's Common Stock, (iii) simplify the Company's consolidated capital structure, and (iv) provide the Company with improved access to capital markets. The Founding Stockholder Exchange was conducted to achieve the goal of providing holders of Labor Shares with representation on the Board of Directors of the Company while maintaining ultimate stockholder direction in the hands of the Founding Stockholders. The transfer of 2,210,000 shares of Class A Common Stock of the Company to Climax Molybdenum Company was conducted to implement an inter-company restructuring. On December 22, 2004, PDC entered into a Letter Agreement (the "Letter Agreement") with Americas Mining Corporation ("AMC") under which AMC agreed to use its reasonable best efforts to cause the Company to enter into a registration rights agreement (the "Registration Rights Agreement") with PDC as soon as possible. The Registration Rights Agreement is anticipated to include the terms set forth in Annex A to the Letter Agreement, as well as terms that are customary for registration rights agreements. The Letter Agreement contemplates that the Registration Rights Agreement will require the Company, as promptly as practicable after the closing of the Transaction described below, to file a shelf registration covering the sale of all of the Common Stock of the Company owned by PDC, which sales may only be effected through underwritten offerings sponsored by the Company during the first six months following the effectiveness of the shelf registration (the "Initial Six Month Period"). Under the Letter Agreement, PDC agreed not to sell its Common Stock in the Company, other than through a secondary offering effected pursuant to the Registration Rights Agreement, from the closing of the Transaction, until the earlier of (i) the end of the Initial Six Month Period and (ii) eight months after the closing of the Transaction. 7 Also under the Letter Agreement, at the request of AMC, PDC expressed its current intent to (i) submit its proxy to vote in favor of the Transaction and (ii) to take all action reasonably necessary to effect simultaneously with the closing of the Transaction the conversion of PDC's Class A Common Stock of the Company into Common Stock. The Transaction involves Minera Mexico, S.A. de C.V. ("MM") becoming a subsidiary of the Company in consideration for the issuance of Common Stock by the Company to AMC for its approximately 99% MM ownership. The foregoing is qualified in its entirety by reference to the Letter Agreement which is filed as Exhibit 1 hereto and incorporated herein by reference. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER Item 5 of the Original Filing is hereby amended and restated in its entirety as follows: (a) Through its right to convert its Class A Common Stock into Common Stock, Phelps Dodge Overseas may be deemed to be the beneficial owner of 8,963,796 shares of Common Stock, representing 11.20% of the equity capital of the Company. Through its right to convert its Class A Common Stock into Common Stock, Climax may be deemed to be the beneficial owner of 2,210,000 shares of Common Stock, representing 2.76% of the equity capital of the Company. As the parent company of Phelps Dodge Overseas and Climax, PDC may be deemed to be the beneficial owner of 11,173,796 shares of Common Stock, representing 13.96% of the equity capital of the Company. To the best knowledge of Phelps Dodge Overseas, Climax and PDC, none of the persons listed on Schedules A, B or C attached hereto is the beneficial owner of any shares of Common Stock, other than J. Steven Whisler, who owns 800 shares of Common Stock, and Ramiro G. Peru, who owns 600 shares of Common Stock. (b) In the event that its Class A Common Stock were converted into Common Stock, Phelps Dodge Overseas, Climax and PDC would have the shared power to vote or to direct the vote, and shared power to dispose or direct the disposition, of such Common Stock. (c) On January 2, 1996, the Exchange Offer and the Founding Stockholder Exchange were completed, resulting in the acquisition by Phelps Dodge Overseas of 11,173,796 shares of Class A Common Stock of the Company. On December 17, 2004, Phelps Dodge Overseas transferred 2,210,000 shares of Class A Common Stock of the Company to PDC as a dividend. Through a series of capital contributions and an inter-company purchase, the 2,210,000 shares of Class A Common Stock of the Company were subsequently transferred to Climax on December 22, 2004. ITEM 6. CONTRACTS ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. Item 6 of the Original Filing is hereby amended and supplemented by adding the following: 8 On December 22, 2004, PDC entered into a Letter Agreement with AMC under which AMC agreed to use its reasonable best efforts to cause the Company to enter into the Registration Rights Agreement with PDC as soon as possible. The description of the Letter Agreement under Item 4 is incorporated herein by reference in its entirety. ITEM 7. MATERIALS TO BE FILED AS EXHIBITS.
