Core Natural Resources, Inc. (NYSE: CNR) provided an update on its ongoing efforts to resume longwall operations at its Leer South mine following a combustion-related event at the mine in mid-January. The company re-entered the mine on June 10th and re-established ventilation, conducted a full inspection, and restored hydraulic pressure along the longwall face. The company confirmed that key longwall components are in good condition. However, on June 26th, the company had to temporarily reseal the affected area of the mine due to elevated carbon monoxide levels.
Despite the delayed restart, Core is reiterating its 2025 coking coal sales volume guidance for the metallurgical segment. The company expects Leer South-related insurance recoveries in excess of $100 million. Core also anticipates providing a more detailed update on ongoing efforts at Leer South in its second-quarter earnings release in early August.
