Castle Valley Mining Complex:
In August 2010, we completed the acquisition of certain mining assets of C.W. Mining Company. The assets acquired are located in Emery and Carbon Counties, Utah and include coal reserves and non-reserve coal deposits, underground mining equipment and infrastructure, an overland belt conveyor system, a loading facility and support facilities. In January 2011, we began production at one underground mine at this complex and for the year ended December 31, 2013, we produced approximately 0.9 million tons of steam coal from this complex. As of December 31, 2013, the Castle Valley mining complex included an estimated 23.3 million tons of proven and probable coal reserves.
