In May 2012, we completed the purchase of certain rights to coal leases and surface property that is contiguous to the Green River and located in Daviess and McLean counties in western Kentucky where we constructed a new underground mining complex.
Pennyrile Mining Complex:
In mid-2014, we completed the initial construction of a new underground mining operation, referred to as our Pennyrile mining complex, which includes one underground mine, a preparation plant and river loadout facility. Production from this new underground mine began in mid-2014 and we produced approximately 0.8 million tons for the year ended December 31, 2015. We believe the possibility exists to expand production up to 2.0 million tons per year with further development of the mine at the Pennyrile complex. Our Pennyrile complex contains approximately 31.2 million tons of proven and probable steam coal reserves as of December 31, 2015.
Our Taylorville property is located in central Illinois and contains approximately 111.1 million tons of proven and probable steam coal reserves. The property is undeveloped, but fully permitted and has potential access to the Norfolk Southern railroad.
