Item 1.04 Mine Safety - Reporting of Shutdowns and Patterns of Violations.
On July 21, 2010, the Dodd-Frank Wall Street and Consumer Protection Act (the “Act”) was enacted. Section 1503 of the Act requires a Current Report on Form 8-K if a company is issued an imminent danger order under Section 107(a) of the Federal Mine Safety and Health Act of 1977 (the “Mine Act”) by the federal Mine Safety and Health Administration (“MSHA”).
On March 25, 2026, Sunrise Coal, LLC, a subsidiary of Hallador Energy Company, received an imminent danger order under Section 107(a) of the Mine Act at Oaktown Fuels, Mine No. 1 ("Oaktown"), located in Knox County, Indiana (MSHA ID# 12-02394). On that date, an MSHA representative alleged that an electrician was performing electrical work on a piece of equipment that was not de-energized. The order required the electrician to cease working until the equipment was de-energized. Oaktown personnel immediately de-energized the equipment. No injuries resulted from the condition and production at the mine was not interrupted. The Company disagrees that the condition constitutes an imminent danger under the Mine Act and intends to contest the 107(a) order.
