Mineral Resource Increase

HYCROFT MINING HOLDING CORP · 2026-04-28 · Importance 72 · Surprise 100

The 2026 Hycroft TRS filed February 18, 2026 reports an approximate 55% increase in measured and indicated mineral resources, updating gold to 16.4 million ounces and silver to 562.6 million ounces at the Hycroft Mine in Nevada. The report supports disclosure of material mineral resources and underpins planned processing strategies that separate sulfide and oxide mineralization. The TRS outlines mill + pressure oxidation (POX) for sulfides and heap leach for oxide/transition material, which will materially influence future capital and operating plans and royalty calculations tied to mine output.
