U.S. subsidiaries of Australian coal mining company Allegiance Coal Ltd. filed for chapter 11 protection on Tuesday, WSJ Pro Bankruptcy reported. The chapter 11 filing includes the New Elk and Black Warrior coal mines located in Colorado and Alabama, respectively, according to papers filed in the U.S. Bankruptcy Court in Wilmington, Del., by Allegiance Coal USA Ltd. The Australian parent company said last week that it is switching away from the production of thermal coal because of a decline in prices for thermal coal delivered to Europe. Instead the company said it is ramping up production of metallurgical coal.
