June 24 (Bloomberg) -- Cloud Peak Energy Inc., a U.S. producer of coal used for power generation, said one person died in an accident at its Spring Creek mine in Montana.
The cause of yesterday’s incident, which involved a single- haul truck, is being investigated, the Gillette, Wyoming-based company said today in a statement. There were no other injuries, it said. The local sheriff and the Mine Safety and Health Administration are on site.
Cloud Peak produced 3.6 million tons of coal from Spring Creek in the first quarter of this year and 17.7 million tons in 2013, according to MSHA data. Cloud Peak shipped 86 million tons last year, according to a company statement in February.
Cloud Peak was spun out from London-based Rio Tinto Group in 2009. Since then, there have been five non-fatal incidents at Spring Creek, according to MSHA data. The last fatality at the mine was in 2006.
