Revett Advancing Its I Bed Development

SPOKANE VALLEY, WA - Revett Mining Company, Inc. reported on development at its Troy Mine in northwest Montana. The financial results are based on US GAAP and all currencies are in United States dollars unless otherwise indicated.

The Company continues to advance its I Bed development on budget, taking into account slower advancement rates in April and May as the Company has advanced approximately 3,955 feet in total, including the east and west headings and sumps and cross-cuts. Revett has also successfully stood steel reinforced concrete arched sets through the dominant splay off the B Fault in the east decline. Also in the east decline, we are currently grouting the main B Fault. Steel reinforced concrete arched sets are now being stood in the west decline at the above mentioned splay of the B Fault. The project remains on track 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. The Company has completed the boring of the first raise, which will serve as secondary egress and ventilation for development and production of the C and I Beds. The ten foot diameter raise is currently being equipped with a 4 foot diameter lined manway for secondary egress.

The planned total development to the North C Bed is approximately 7,500 feet (including muck bays and cross-overs). Continued development to access 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.

John Shanahan, Revett's President and CEO stated "We continue to advance redevelopment at Troy on plan and remain focused on returning to limited commercial production in the fourth quarter of 2014. Being back in operation at Troy is a key component in our near and long term plans and we remain fully committed to returning to being a safe and efficient operator at Troy and to finalizing permitting and developing and operating Rock Creek".
