The temporary closure of operations at the Troy mine on Wednesday, December 5th, was the result of a magnitude 2.9 earthquake 22 miles southwest of Libby, according to the U. S. Geological Survey (USGS). The depth of the quake was at .6 miles, says the USGS. Troy operations were stopped when rock and dirt started falling in the mine. Miners have not yet returned back to work.
