Created in January 2025 through the merger of Arch Resources and CONSOL Energy, Core Natural Resources mines and exports metallurgical and high-calorific-value thermal coal from a large U.S. operation serving steel, infrastructure, and energy markets worldwide. Based in Canonsburg, Pennsylvania, the company operates 11 mines—including eight longwalls—and supports its global reach with ownership positions in two East Coast marine export terminals. Through its CONSOL Innovations subsidiary, Core is also developing advanced carbon-based materials, including coal-derived aerospace tooling and composite decking made with coal waste.
