Hycroft Expands High-Grade Silver Systems at Brimstone and Vortex — Hycroft Mining Holding Corporation

Event summary

Hycroft extended the Vortex high-grade silver system by ~150 meters west, with drill hole H26D-6088 intersecting 12.5 meters at 375.41 g/t silver, including 4.2 meters at 748.02 g/t silver.
Brimstone high-grade silver continuity confirmed up-dip, with hole H26D-6169 intersecting 82.7 meters at 87.52 g/t silver and 0.77 g/t gold, including 19.4 meters at 108.19 g/t silver and 2.10 g/t gold.
Potential feeder target below Brimstone advanced with newly confirmed stockwork veining across a wider zone.
Since August 2025, Hycroft has completed ~15,585 meters of core drilling out of a planned 26,000-meter program.

The big picture

Hycroft's latest drill results reinforce the potential for high-grade underground silver mining at its Nevada-based Hycroft Mine. The continued expansion of the Brimstone and Vortex systems aligns with the company's strategy to transition from heap leach operations to processing sulfide mineralization. The discoveries represent a significant value driver for Hycroft, positioning it to capitalize on favorable precious metals market dynamics.
