Hycroft Mining Holding Corporation has intersected 30.5 meters grading 780.53 g/t silver and 0.49 g/t gold from hole H26D-6090 at the Vortex system within the Hycroft Mine in Nevada.

The interval included a higher-grade zone of 11.2 meters at 1,664.80 g/t silver and 0.85 g/t gold, with a core section returning 5.5 meters at 2,249.39 g/t silver and 1.01 g/t gold. Additional drilling at Vortex, including hole H26D-6166, returned 20.0 meters at 460.82 g/t silver and 0.32 g/t gold. Meanwhile, step-out drilling at the Brimstone system extended mineralization to the north, where hole H26D-6167A intersected 5.5 meters at 1,345.27 g/t silver and 0.56 g/t gold, including 1.8 meters at 4,074.00 g/t silver.

Hole H26D-6172 also tested the northern flank of Vortex and intersected a high-grade gold interval higher in the known system, returning 6.1 meters at 21.12 g/t gold, including 1.5 meters at 43.00 g/t gold.

The ongoing 2025-2026 Exploration Drill Program follows up on previous exploration successes at Brimstone and Vortex established during earlier drilling campaigns. Hycroft maintained a strong balance sheet with $220.5 million in unrestricted cash and no debt as of its Q2 2026 financial report to support ongoing activities.

“These are some of the strongest results we've seen from the Drill Program. We're not just confirming the high-grade silver system, we're extending it and are consistently intersecting thick, continuous, high-grade mineralization. We have also intersected a high-grade gold interval higher in the known system that we intend to follow up on as we are seeing an increasing number of higher-grade gold intercepts in this area of Vortex. These results continue to confirm our exploration strategy and underpin the potential for a high-grade underground mine. With the system open in all directions and at depth, we see a clear opportunity for continued expansion and growth of these high-grade mineralized systems.” — Diane Garrett, Executive Chairman and CEO

Hycroft is planning follow-up drilling at Vortex to determine the orientation and extent of the high-grade gold mineralization intersected in hole H26D-6172. The remaining schedule of the drill program includes approximately 7,200 meters of core drilling at Brimstone and 3,000 meters at Vortex.
