Hycroft Silver Intercepts 748 g/t at Vortex, Extends Both Zones

Hycroft Mining published new drill results from its Nevada mine on Wednesday, and the numbers widen both the Brimstone and Vortex high-grade silver systems. The assays come from the company's 2025-2026 exploration program and include the widest intercept yet at Brimstone and a 150-meter extension to the west at Vortex.

At Brimstone, hole H26D-6169 cut 82.7 meters grading 87.52 grams per tonne silver and 0.77 g/t gold. Within that, a 19.4-meter interval ran 108.19 g/t silver and 2.10 g/t gold, and a separate 0.7-meter section assayed 14.35 g/t gold. The company said grades at this level could support either an open pit or underground mine design, giving the deposit development optionality. The Brimstone footprint now measures approximately 300 meters north-south by 500 meters east-west down-dip. It stays open in all directions and at depth.

Drilling also tested the potential feeder zone below Brimstone, targeting a geophysics anomaly from 2025. Holes H26D-6089 and H26D-6089X stepped out roughly 90 meters down-dip from late-2025 intercepts. They returned alteration and geochemistry consistent with the Brimstone fluid pathway, Hycroft said. Hole H26D-6089X contained an 18-meter zone of stockwork veining, including 1.5 meters at 120.00 g/t silver. The company said the results support the feeder interpretation but noted that drilling remains high in the system and will advance toward the target. Another 7,200 meters of core are planned at Brimstone for the rest of the program.

At Vortex, the strike length now exceeds one kilometer and the width passes 500 meters. Hole H26D-6088 extended high-grade silver about 150 meters to the west. It returned 12.5 meters at 375.41 g/t silver, including 4.2 meters at 748.02 g/t silver. That hole offsets an earlier intercept from H25D-6072 and fits the company's structural targeting model. Hycroft plans roughly 3,000 meters of core at Vortex, targeting extensions to the north, south, east, and west.

Hycroft is a US-based gold and silver company operating the Hycroft Mine in northern Nevada, one of the world's larger precious metals deposits. The company has a history of heap-leach operations and is working toward processing sulfide mineralization. Alex Davidson, vice president of exploration, reviewed and approved the technical information in the release.

The drill program's next phase will focus on expanding the known zones and testing the feeder target at depth. For a company like Hycroft, the Brimstone and Vortex discoveries represent a potential shift in the asset's profile. The current resource base at Hycroft is dominated by lower-grade, bulk-tonnage material; high-grade silver zones could improve project economics and attract partner interest. The 7,200 meters of core at Brimstone and 3,000 meters at Vortex will keep the exploration pipeline active through 2026. Investors tracking the gold and silver space will watch for step-out holes that extend the systems further and for deeper intercepts that confirm the feeder model.
