Item 1.01      Entry into a Material Definitive Agreement.

        On March 28, 2006, CDE Australia Pty Ltd. (“CDEA”), a wholly-owned subsidiary of Coeur d’Alene Mines Corporation (the “Company”), entered into an amendment (the “Amendment”) to the Silver Sale and Purchase Agreement, dated April 7, 2005, (the “Agreement”) between CDEA and Cobar Operations Pty Limited (“Cobar”), a wholly-owned subsidiary of CBH Resources Ltd (“CBH”), an Australian mining company. Entry into the original Agreement was reported by the Company in its Form 8-K dated April 7, 2005. Cobar owns and operates the Endeavor Mine in Australia. Pursuant to the Agreement, CDEA agreed to buy, and Cobar agreed to sell, the silver contained in ore to be mined at the Endeavor Mine for a total of approximately US$38.5 million.

        The modifications to the original Agreement effected by the Amendment are as follows:

  CDE Australia Pty Ltd (“CDEA”) will receive a maximum of 20.0 million ounces of payable silver from the Endeavor Mine, an increase from 17.7 million ounces.

  The 50/50 sharing in silver prices above US$5.23 per ounce beginning in June 2007 will be amended as follows:

  The silver price sharing will be altered so that it will commence when a total of 2,073,000 ounces of payable silver has been delivered to CDEA or June 2007, whichever occurs later; and

  The threshold silver price for price participation will be increased to US$7.00 per ounce from US$5.23 per ounce.

In return, CDEA will make available a loan facility of A$15 million to Cobar on the basis of a parent company guarantee from CBH. The loan will bear interest at the fixed rate of 7.75% and is repayable out of the remaining A$30 million still to be paid by CDEA under the terms of the original Agreement.

Cobar will not be entitled to draw down the loan facility unless (a) it has received unconditional commitments from underwriters or purchasers for subscriptions for CBH common shares aggregating A$19.5 million; (b) an independent report to be prepared on Cobar’s operating plan confirms its technical feasibility; and (c) CDEA is satisfied that the Endeavor Mine is operating substantially in accordance with Cobar’s operating plan.

Finally, the payment by CDEA of the remaining A$15 million from the original transaction will be made once (a) the pastefill plant at the Endeavor Mine operates to pre-agreed criteria for 30 consecutive days; and (b) the mill operates in the ordinary course for three consecutive months at an average rate equivalent to 1.2 million tonnes per annum and the recovered silver from operations is equal to or exceeds the projected number of ounces.
