Hycroft Mining Holding Corporation has intersected 82.7 meters at 87.52 g/t silver and 0.77 g/t gold at the Brimstone high-grade system, moving mineralization closer to surface at the Hycroft Mine in Nevada.

Assays from hole H26D-6169 included a 19.4-meter interval grading 108.19 g/t silver and 2.10 g/t gold, alongside a 0.7-meter section returning 14.35 g/t gold. In addition, step-out drilling at the Vortex high-grade silver system extended mineralization approximately 150 meters to the west. Hole H26D-6088 intersected 12.5 meters at 375.41 g/t silver, including a 4.2-meter interval of 748.02 g/t silver.

The ongoing 2025-2026 Exploration Drill Program has completed approximately 15,585 meters of core drilling out of a planned 26,000-meter program. For the remainder of the schedule, Hycroft plans to drill approximately 7,200 meters of core at Brimstone and 3,000 meters of core at Vortex, targeting northern, southern, and eastern extensions as well as the western zone.

Diane Garrett, Executive Chairman and CEO, commented: “Our drilling continues to confirm the size, continuity, and growth potential of the high-grade silver systems at Brimstone and Vortex. At Brimstone, we're expanding high-grade silver mineralization closer to surface while increasing confidence in the potential for a feeder system at depth. At Vortex, we've extended the high-grade zone an additional 150 meters to the west. Together, these results reinforce the case for a high-grade underground mine. With a strong, debt-free balance sheet, our operational focus this year is to determine the optimal path forward for the mine and drive shareholder value.”

The Hycroft Mine is supported by an updated S-K 1300 Technical Report Summary published in June 2026, which outlined a 51-year mine life with average annual production of 204,000 ounces of gold and 6.8 million ounces of silver. The asset has a long operating history of heap leach activities and is advancing technical studies to process sulfide mineralization using pressure oxidation technology.

In the wider district, Blossom Gold Inc. reported drill results at the Rosebud Open-Pit Heap-Leach Project, including an interval of 28.0 meters at 1.682 g/t gold.

Hycroft shares fell 8.09% to close at $24.19 on August 18, 2026.
