For the year ended December 31, 2015, 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, 2015, 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. In addition, for the year ended December 31, 2015, lessees of our Elk Horn properties produced approximately 1.7 million tons of coal. As of December 31, 2015, we controlled an estimated 171.5 million tons of proven and probable coal reserves and an estimated 288.8 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, 2015, the Tug River mining complex included an estimated 21.8 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, 2015, included an estimated 7.5 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.
Elk Horn Coal Leasing:
In June 2011, we completed the acquisition of 100% of the ownership interests in Elk Horn and, as of December 31, 2015, included an estimated 100.1 million tons of proven and probable coal reserves. Elk Horn is a coal leasing company located in eastern Kentucky that provides us with coal royalty revenues.
Deane Mining Complex:
Our Deane mining complex was located in eastern Kentucky and included one underground steam coal mine that was idle during the year ended December 31, 2015. The infrastructure consisted of a preparation plant utilizing heavy media circuitry capable of cleaning coarse and fine coal size fractions, as well as a unit train loadout facility with batch weighing equipment capable of loading in excess of 10,000 tons into railcars in approximately four hours. The Deane complex was sold to a third party in December 2015.
Rhino Eastern Mining Complex:
Our Rhino Eastern mining complex was previously owned through a joint venture where we had a 51% membership interest in, and serve as manager for, the mining complex located in Raleigh and Wyoming Counties, West Virginia. The joint venture was dissolved in January 2015 and an affiliate of Patriot, our previous joint venture partner, assumed ownership and operation of the mining complex.
