For the year ended December 31, 2016, we operated two mining complexes located in Central Appalachia consisting of one active underground mine and three surface mines. For the year ended December 31, 2016, the mines at our Tug River and Rob Fork mining complexes produced an aggregate of approximately 0.4 million tons of steam coal and an estimated 0.3 million tons of metallurgical coal. As of December 31, 2016, we controlled an estimated 70.7 million tons of proven and probable coal reserves and an estimated 46.8 million tons of non-reserve coal deposits in Central Appalachia.
Tug River Mining Complex:
Our Tug River mining complex consists of property in Kentucky and West Virginia that borders the Tug River. As of December 31, 2016, the Tug River mining complex included an estimated 21.4 million tons of proven and probable coal reserves. Our Tug River mining complex produces coal from two company-operated surface mines, which includes one high-wall mining unit. Coal production from these operations is delivered to the Tug Fork preparation plant for processing and then transported by truck to the Jamboree rail loadout for blending and shipping. The Jamboree loadout is located on the Norfolk Southern Railroad and is a modern unit train loadout with batch weighing equipment.
Rob Fork Mining Complex:
Our Rob Fork mining complex is located in eastern Kentucky and, as of December 31, 2016, included an estimated 7.2 million tons of proven and probable coal reserves. Our Rob Fork mining complex produces coal from one company-operated surface mine and one company-operated underground mine. The Rob Fork mining complex is located on the CSX Railroad and consists of a modern preparation plant utilizing heavy media circuitry that is capable of cleaning coarse and fine coal size fractions and a unit train loadout with batch weighing equipment. The mining complex has significant blending capabilities allowing the blending of raw coals with washed coals to meet a wide variety of customers’ needs.
