The legal action, brought by Levi & Korsinsky, LLP, targets the period between October 14, 2024, and May 4, 2026. Investors allege that CEO James C. Grech, CFO Mark A. Spurbeck, and former global operations president Marc E. Hathhorn touted the mine’s progress as "on time and on budget" while deploying repurposed, untested equipment that had been sitting idle for eight years. By the time the full extent of the electrical and mechanical breakdowns surfaced in May 2026, the stock had plummeted from a high of $39.50 to $25.00.

Internal records cited in the complaint suggest that warning signs were evident long before the market was notified. The company allegedly ignored issues such as roof deterioration, floor softening, and equipment misalignment while continuing to project confidence in its production targets. The lawsuit seeks to recover losses for shareholders who purchased stock based on these allegedly misleading assurances. The deadline for investors to apply for lead plaintiff status is August 24, 2026.
