Revett Provides Update on Troy Mine Development and Rock Creek Permitting

Troy Mine I Bed Development

The Company continues to advance the I Bed development having completed development through the dominant splay off the B Fault and the main B Fault on the east decline. As of June 30th 2014, the Company has completed approximately 4,700 feet against the 7,500 feet required for planned development of the North C Bed. The project remains on schedule and within budget for development of the North C Beds in the third quarter of this year with a return to limited commercial production in the fourth quarter of 2014. Access to the I Beds requires an additional 5,900 feet of single decline. If development continues as planned, it is estimated full production may resume by mid-2015.

A concrete batch plant was recently acquired to facilitate more-efficient, on-demand “shotcrete” for ongoing development and future production needs. The plant will ensure that shotcrete is available when needed for day and evening shifts.

Rock Creek Permitting

The U.S. Forest Service (USFS), as lead agency, has made considerable progress towards the completion of a Supplemental Environmental Impact Statement (SEIS). The Company meets on a regular basis with the USFS, its third-party contractor, and cooperating agencies. When issued, the SEIS, together with the Biological Opinion that was upheld by the Ninth Circuit Court of Appeals in November 2011, will form the basis of a reissued Record of Decision (ROD). Once a draft SEIS has been compiled, input from co-operating agencies will be sought and included, and an SEIS will be issued for public comment.

In parallel, the Company is working to obtain necessary permits from the State of Montana Department of Environmental Quality (MDEQ). On April 11, 2014 the MDEQ issued a draft permit to the Company for the discharge of stormwater during Phase I construction activities with the public comment period ending on May 15, 2014. The Company has also been working with a contracted technical consultant and MDEQ on the finalization of an Air Quality Permit.

John Shanahan, Revett’s President and CEO stated, “We remain fully focused on returning the Troy Mine to producing capability and completing the SEIS and ancillary state permits for Rock Creek as quickly as practicable. We understand that each project must be completed to the highest standards possible and we remain committed to meeting this objective.”
