Potential Value Extraction From Tails

Tailings as of December 2025:

  • 10.4 million DST of tailings consisting of

    • 50 Moz of Silver (5 oz/ton or 165 grams/tonne ("gpt"))

    • 567 Koz of Gold (~2 gpt)

    • 309 Mlbs of Zinc

    • 203 Mlbs of Lead

    • 27 Mlbs of Copper

    • 1.3 Mlbs of Nickel

      Metals in tailings represent ~$6.8B in gross value

    • Includes other critical minerals - Arsenic, Barium, Bismuth, Cadmium, Chromium, Gallium, Germanium, Manganese, Vanadium

  • Opportunity for reprocessing includes marketing, participation in

    DoD/DoE CM initiatives

  • Reprocessing tailings could reduce storage costs and reclamation obligations

  • Next step: Phase 4 metallurgical test work to be completed mid-2026

Underhand Closed Bench (UCB) Method



Large-scale blasting proactively helps manage seismic risk and increases throughput

More innovative: uses advanced drilling and blasting techniques to fragment the mineralized ore zone

Safer: miners work below engineered backfill and above a de-stressed zone

More productive:

larger and less handheld equipment, more task-based mining

More controlled: Allows for greater control of the release of seismic energy, resulting in improved safety

Lucky Friday Major Projects & Business Improvement Initiatives

Pond 5 tailings project

Lucky Friday Projects

  • Surface Cooling Project on track for mid-2026 completion

  • Pond 5 tailings project advancing, expanding tailings capacity projected to 2044

  • Further (medium to long-term) operational upside potential from:

    • Switching to owner operated production drilling

    • Business Improvement Initiatives geared towards mine and mill tonnage optimization. Work continues to evaluate opportunities identified in 2025
