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

The Company filed the 2026 Hycroft TRS on February 18, 2026, which supports disclosure of measured and indicated mineral resources of approximately 16.4 million ounces of gold and 562.6 million ounces of silver, a roughly 55% increase in measured and indicated resources. The Company continued the 2025–2026 Exploration Drill Program, completing approximately 9,255 meters across 26 exploration holes in the high‑grade Brimstone and Vortex silver systems since August 3, 2025. Metallurgical test work in Q1 2026 progressed crushing, grinding, flotation, pressure oxidation and leaching tests to improve gold and silver recoveries and to inform a sulfide milling and POX processing plan; trade‑off studies on possible roasting are planned. The Company plans to add two core rigs (for four total) to accelerate drilling and is assessing underground high‑grade mining scenarios and restart potential for leachable oxide/transition material in 2026.
