We operate two mining complexes located in Northern Appalachia consisting of one company-operated underground mine and two company-operated surface mines. For the year ended December 31, 2016, these mines produced an aggregate of approximately 0.4 million tons of steam coal. As of December 31, 2016, we controlled an estimated 21.3 million tons of proven and probable coal reserves and an estimated 85.6 million tons of non-reserve coal deposits in Northern Appalachia.
Hopedale Mining Complex:
The Hopedale mining complex includes an underground mine located in Hopedale, Ohio approximately five miles northeast of Cadiz, Ohio. As of December 31, 2016, the Hopedale mining complex included an estimated 21.3 million tons of proven and probable coal reserves. Coal produced from the Hopedale mine is first cleaned at our Nelms preparation plant located on the Ohio Central Railroad and the Wheeling & Lake Erie Railroad in Cadiz, Ohio and then shipped by train or truck to the customer. The infrastructure includes a full-service loadout facility.
Sands Hill Mining Complex:
We currently operate one surface mine at our Sands Hill mining complex, located near Hamden, Ohio. The infrastructure includes a preparation plant along with a river-front barge and dock facility on the Ohio River. Coal mining at our Sands Hill complex is expected to cease during the second quarter of 2017 due to weak market demand for coal from this complex. We will continue our limestone aggregate business at the Sands Hill complex for the next twelve to eighteen months.
