	Grupo México, S.A. de C.V. (“Grupo México”), Grupo Minero México Internacional, S.A. de C.V. (“GMMI”), Americas Mining Corporation (“AMC”), and SPHC II Incorporated (“SPHC II”), (collectively, Grupo México, GMMI, AMC, and SPHC II, the “Reporting Persons”) hereby amend the report on Schedule 13D regarding shares of Southern Peru Copper Corporation (the “Company”), originally filed on January 12, 1996, as further amended on March 6, 1996, on November 19, 1999, on October 13, 2000, on May 17, 2001, on July 16, 2001, on February 11, 2003, on March 31, 2003, October 25, 2004 and on November 1, 2004 (collectively with this Amendment No. 10, the “Schedule 13D”). Unless otherwise indicated, capitalized terms used but not defined herein shall have the same meanings assigned to them in Schedule 13D.
Item 1.	Security and Issuer
	This Schedule 13D relates to Common Stock of the Company (the “Common Stock”), $0.01 par value per share and Class A Common Stock (the “Class A Common Stock”) of the Company, $0.01 par value per share (collectively, the “Company Common Stock”).

Item 4.	Purpose of Transaction
	Item 4 is hereby amended and supplemented by adding the following:
	On December 22, 2004, AMC and Phelps Dodge Corporation, a New York Corporation (“PD”) entered into a Letter Agreement (the “Letter Agreement”) whereby AMC agreed to use its reasonable best efforts to cause the Company to enter into a registration rights agreement (the “Registration Rights Agreement”) with PD 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 merger, announced on October 21, 2004 (the “Transaction”), to file a shelf registration covering the sale of all of PD’s Company Common Stock, 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, PD agreed not to sell its Company Common Stock, 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. Also under the Letter Agreement, at the request of AMC, PD 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 PD’s Class A Common Stock into Common Stock. 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
