Mines & Facilities

We currently operate seven mining complexes in two operating regions: Illinois Basin and Appalachia.

At December 31, 2019, we had approximately 1.693 billion tons of coal reserves in Illinois, Indiana, Kentucky, Maryland, Pennsylvania and West Virginia. We produce a diverse range of thermal and metallurgical coal with varying sulfur and heat contents, which enables us to satisfy the broad range of specifications required by our customers. In 2019, we sold 39.3 million tons of coal and produced 40.0 million tons. The coal we sold in 2019 was approximately 26.2% low-sulfur coal, 65.2% medium-sulfur coal and 8.6% high-sulfur coal. In 2019, approximately 78.8% of our tons sold were purchased by United States electric utilities and 17.9% were sold into the international markets through brokered transactions. The balance of our tons sold were to third-party resellers and industrial consumers. For tons sold to United States electric utilities, 100% were sold to utility plants with installed pollution control devices. The Btu content of our coal ranges from 11,400 to 13,200.
