Revett Minerals Updates Progress at Troy Mine

Revett Minerals Inc. ("Revett" or the "Company") provides an update on progress towards recommencement of operations at its Troy Mine in northwest Montana.

Crews continue to perform preparatory work necessary to gain access to the A and C Bed mining areas; however, progress has been slower than expected due mainly to the time required to receive regulatory approvals. This preparatory work includes scaling, bolting, shotcrete application, and the installation of arched reinforced concrete sets in the Lower Main Haulage travel-way. The Company recently received approval from the Mine Safety and Health Administration ("MSHA") to initiate access through the B Fault and has now commenced this operation which includes additional ground support at the B Fault and other related development tasks.

Monitoring of both the Middle Quartzite and Lower Quartzite areas continues via the underground geophone system that was installed at the beginning of 2013. Interpretation of microseismic activity recorded by the geophones has shown encouraging results over the past few months. Ongoing recordings suggest no significant detrimental effects to the Lower Quartzite workings. Additional inspections are required in the Lower Quartzite haulage route to confirm that there is no further structural damage; but, we remain encouraged with our observations to date.

Once dewatering is completed, mine ventilation re-established, and underground utilities re-routed, we will need to submit a final plan of operation to MSHA for approval before recommencing production. We believe production will begin before the end of the second quarter, but it is not possible to provide an exact date until the critical tasks outlined above are completed and final MSHA approvals have been obtained.

John Shanahan, Revett's President and CEO stated "Even though the review and approval process has taken longer than expected, we are encouraged with continuing underground progress and data supporting our objective to return to operations safely. Development work and planning now being done will ultimately support and strengthen our short and long term goals for Troy Mine's current 8 year life-of-mine as well as future development of the I Bed and JF resources."
