U.S.–based silver miner Coeur d'Alene Mines Corp. plans to issue $350 million of unsecured notes and enter into a $100 million secured revolving credit facility. We are assigning our 'B+' corporate credit rating to the company and 'BB-' issue-level rating to the proposed unsecured notes, with a recovery rating of '2'. The stable rating outlook reflects our view that the company's operating performance will be able to support the rating despite price volatility and high operating costs.
