Another coal company has entered a potential bankruptcy deal that could allow two idle Wyoming coal mines to reopen. Bristol, Tennessee-based Contura Energy has announced it has reached a tentative deal to pay Jasper, Alabama-based FM Coal $90 million to take the Eagle Butte and Belle Ayr mines. A bankruptcy court in August approved the mines’ purchase by Contura but the deal has been held up while the U.S. government seeks payment of federal mineral royalties.
