The Spokesman Review reports that federal officials have joined Idaho fire investigators to probe a pair of fires at the Lucky Friday Mine in Idaho's panhandle.
The most recent fire, reported on July 26, led to an evacuation after an employee said he smelled smoke. The cause of the fire, which was extinguished on July 27, is still unknown. A previous fire broke out at the mine on July 5.
The Lucky Friday Mine was the scene of an accident in April, where a miner was killed following a roof collapse more than a mile beneath the surface. Hecla mining, which operates the Lucky Friday operations, employs about 275 men and women.
