Why Core Natural Resources Stock Topped the Market Today

Core provided an update on its longwall operations at the Leer South mine in West Virginia. For those unfamiliar, longwall mining is a modern extraction method in which a long face of coal is mined in one single, large slice by a specialty machine called a shearer. Earlier this month, Core officials reentered the sealed area of the facility, finding that the longwall equipment was "largely unaffected" by the event.
