What is the primary purpose of this 10-Q/A filing?

This filing is an amendment (10-Q/A) to Southern Peru Copper Corporation's previously filed Form 10-Q for the fiscal quarter ended March 31, 2004. Its purpose is to amend and clarify specific portions of Item 1 (Financial Statements) and Items 2 and 3 (Management's Discussion and Analysis of Financial Condition and Results of Operations) of the original report.

Does this amended filing provide updated financial information beyond March 31, 2004?

No, this amendment does not update the disclosure to reflect any events that have occurred since March 31, 2004. All financial information and discussions pertain to the period ending on that date.

What types of financial statements are included in this report?

The filing includes unaudited condensed consolidated financial statements, specifically the Statement of Earnings, Balance Sheet, and Statement of Cash Flows for the three months ended March 31, 2004, along with comparative data for prior periods where applicable.

Why was this amendment filed nearly a year after the original report?

The original 10-Q was filed on May 7, 2004, and this amendment was filed on February 24, 2005. The delay suggests that SCCO identified specific areas in their Q1 2004 filing that required clarification or correction, which they are now addressing through this amended filing.
