Rock Creek Project Continuing Efforts To Obtain Permits

SPOKANE VALLEY, WA - Revett Mining Company, Inc. reported that it is continuing its efforts to obtain permits and approvals for its Rock Creek project. The U.S. Forest Service is expected to issue a Draft Supplemental Environmental Impact Statement for public comment in mid-2015. An orderly shutdown of mining and milling operations at the Troy mine and the transition to care and maintenance were completed during February 2015.

As previously reported, the Company has entered into an agreement and plan of merger with Hecla Mining Company and Hecla's wholly-owned merger subsidiary, RHL Holdings, Inc. pursuant to which, and subject to Revett stockholder approval, a subsidiary of Hecla will be merged with and into Revett (with Revett surviving the merger as a wholly-owned subsidiary of Hecla) and each outstanding share of common stock of Revett will be exchanged.
