Hycroft Continues to Intersect High-Grade Silver at Brimstone
Hycroft Mining announces significant drill results from its 2024 exploration program at the Brimstone site. Key highlights include an exceptional intersection of 18.2 meters of 1,987.35 g/t silver and 0.35 g/t gold in hole H24D-6010. The drilling confirms continuity of the high-grade silver dominant trend, with multiple intervals exceeding 1,000 g/t silver. Notable results include sections containing up to 20,280 g/t silver. The Brimstone trend remains open both up and down-dip, with additional drill results pending. Petrography and geochemistry studies indicate at least three different overlapping high-grade mineralizing events likely derived from a magmatic source.

Insights
The latest drill results from Hycroft's Brimstone zone represent a significant discovery with exceptional high-grade silver intersections. The standout result of 18.2 meters at 1,987.35 g/t silver including sections with up to 20,280 g/t silver indicates a potentially transformative high-grade zone. The mineralization shows strong continuity and remains open in multiple directions, suggesting further upside potential.
These grades are substantially higher than typical silver deposits, with the highest-grade intercepts being among the richest reported in North America. The multiple high-grade intervals and significant widths could materially improve the project's economics through higher-grade feed in early mine years. The identification of multiple mineralizing events and magmatic source suggests a robust system with potential for additional discoveries.
The structural and geological findings are particularly noteworthy. The identification of three distinct mineralizing events from a magmatic source indicates a complex, multi-phase system typical of major precious metal deposits. The discovery of a previously unknown intrusive with higher gold-to-silver ratios opens new exploration potential and suggests the system may be more extensive than previously understood.
The continuity demonstrated by hole H24D-6010, positioned 45 meters from previous high-grade intersections, significantly de-risks the geological model. The combination of well-defined veins and broad mineralized intervals suggests both high-grade selective mining potential and bulk mining opportunities, offering flexible mining approaches that could optimize project economics.

Alex Davidson, Vice President, Exploration commented: "The objective of the 2024 drill program in Brimstone is to improve continuity within the high-grade and define the structural framework to drive down-dip targeting of the un-drilled Brimstone trend. Geochemistry, structural, assay, and geological data collected from this year's drill program has greatly refined the understanding and targeting strategy to extend the Brimstone trend. Information from drilling in conjunction with petrography work completed earlier in 2024 indicates at least three different overlapping high-grade mineralizing events within this trend that are likely derived from a magmatic source. Targeting for 2024 has shown success by stepping out from defined zones of mineralization while continually defining the geometry of the high-grade trend. The spectacular results in core hole H24D-6010 (18 meters of 1,987.35 g/t Ag) establishes continuity of the high-grade silver dominant trend as it was drilled approximately 45 meters from high-grade mineralization intersected in recent drill holes. Holes 6003 and 6009 extends Brimstone down-dip. Core hole H24D-6004 crossed a previously unrecognized intrusive, which the results from this hole contain a higher gold to silver ratio opening yet another target."
Diane Garrett, President and CEO commented: "We continue to be extremely pleased with the results from the 2024 drill program. The results from Brimstone continue to deliver extremely high grades of silver in well-defined veins with continuity. Vortex is similarly delivering high-grade silver, and we are beginning to see higher gold values as we drill deeper. As we work to complete the engineering and economic studies, the objective of the 2024 drill program is to add high-grade mining opportunities in the early years of the project that could potentially be accessed in an open-pit or underground or combination open-pit and underground operation. I want to personally thank the technical team for their outstanding work in identifying these two new high-grade trends that are adding significant value to an already world class asset."
