Revett Minerals Inc. officials attribute heavy rains in November to the falling rock that caused the company to first scale back operations and then shut down the Troy Mine.
Revett communications director Monique Hayes tells the Missoulian (http://bit.ly/14XSF6q ) the company recently completed underground inspections with the Mining Safety and Health Administration.
Workers are removing loose rock along the main haul route, draining flooded areas and solidifying walls, but a portion of the mine corridor remains blocked.
The company is tentatively planning to have the mine open again by the first week of April.
