TABLE OF CONTENTS

Item 4.02.           Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

Apex Silver Mines Limited (the “Company”) has concluded that it did not properly determine the fair value of certain of its metals derivative positions for the quarter ended March 31, 2008.  The correction will result in a reduction of the fair value of the derivative liability at March 31, 2008 and a decrease to the non-cash loss on commodity derivatives included in the operating results for the first quarter 2008.

Pursuant to the covenants of the $225 million project finance facility for the San Cristobal mine (the “Facility”), the Company was required to provide price protection for a portion of the planned production of metals from the mine.  The Company entered into certain metal derivative positions utilizing primarily forward sales but also puts and calls to comply with the Facility covenants.  Pursuant to Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities”, the Company records the derivative positions at their fair value on its balance sheet and records the change in fair value to current earnings at the end of each reporting period.

In the first quarter of 2008, the Company adopted Financial Accounting Standards No. 157 (“FAS No. 157”), “Fair Value Measurements”, which requires that, in the measurement of certain liabilities, consideration be given to the risk of non-performance.  In adopting FAS No. 157 with respect to its open metals derivative liability positions at March 31, 2008 the Company failed to consider non-performance risk, including its own credit risk.  Consideration of non-performance risk will reduce the fair value of the derivative liability at March 31, 2008 and decrease the non-cash loss on commodity derivatives included in operating results for the first quarter 2008. The Company is in the process of evaluating the amount of the correction but expects it will be more than $40 million. The reduction in the fair value of the liability results from discounting the cash flows relating to the commodity derivative contracts using higher interest rates reflective of the Company’s increased credit risk. As the correction relates solely to fair value measurements, it does not affect the company’s historical or future cash flow or the timing or amount of actual payments required to settle the applicable liabilities.

After discussions with management, the Audit Committee determined on July 30, 2008 that the Company’s previously issued financial statements for the quarter ended March 31, 2008 should no longer be relied upon and should be restated. The Company and the Audit Committee have also discussed the matters disclosed in this filing with PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm. The Company intends to file a Form 10-Q/A which includes restated interim financial statement as of and for the three months ended March 31, 2008, as soon as practical.
