Core Natural Resources, Inc. (NYSE: CNR) Takes Action at Leer South Mine – Combustion-Related Activity Addressed

Core Natural Resources, Inc., a prominent producer and exporter of high-quality, low-cost coals, disclosed an incident at its Leer South mine through a recent press release. The company confirmed that it was implementing measures to extinguish isolated combustion-related activity at the active longwall panel within the Leer South mine.

In a press release issued on January 16, 2025, Core Natural Resources stated that it plans to temporarily seal the active longwall panel to address the combustion-related activity. Based on ongoing discussions with regulatory bodies, Core anticipates that Leer South mine could resume development work utilizing continuous miners within the next three months and is expected to recommence longwall mining by mid-year.

Paul A. Lang, the Chief Executive Officer of Core, expressed appreciation for the efforts of the Leer South personnel in managing the situation effectively, emphasizing the collaborative support received from regulatory agencies. Lang acknowledged the potential production impact, estimating a temporary loss of around two quarters of longwall production. However, he reassured stakeholders that the company is taking necessary precautions to safeguard the mine’s integrity, equipment, and infrastructure.

The company highlighted that the re-entry process at Leer South will be executed in multiple phases, starting with constructing ventilation controls followed by the resumption of continuous miner development. This phased approach is expected to facilitate the advancement of work on future longwall panels, enhancing operational efficiency in the second half of the year.

George J. Schuller Jr., the Chief Operating Officer of Core, mentioned proactive steps underway to prevent similar incidents in the future. This includes initiatives focusing on monitoring, degassing, and deploying mitigation systems, aiming to avert potential operational disruptions.
