The Company is self-insured for certain risks, including physical damage and operational liability, related to our non-leased underground mining equipment allocated among four mining units dispersed over seven miles. The Company records a liability for self-insured risks when a loss is both probable and reasonably estimable. The Company had no accrual for self-insurance liabilities as of June 30, 2025 or December 31, 2024. The Company also self-insures for workers’ compensation claims under a guaranteed cost program. Under this program, the Company is responsible for the first $1.0 million per claim up to an aggregate of $4.0 million annually. The Company has restricted cash of $23.1 million and $3.4 million as of June 30, 2025, and December 31, 2024, respectively, which represents cash held and controlled by third parties and is restricted primarily for future workers’ compensation claim payments and the $19.0 million compensating balance on our Term Loan (as discussed in “Note 5 – Bank Debt” above). The Company had $5.3 million and $4.3 million of workers’ compensation reserve as of June 30, 2025 and December 31, 2024, respectively, in “accounts payable and accrued liabilities” on the condensed consolidated balance sheets.
