Hycroft Mine Drill Program To Expand-Advance High-Grade At Brimstone & Vortex

WINNEMUCCA, NV – Hycroft Mining Holding Corporation (HYMC) is initiating its 2025-2026 Exploration Drill Program at the Hycroft Mine, located in Nevada. The Exploration Drill Program comprises approximately 14,500 meters of core drilling utilizing two drill rigs. The Program is designed to expand and advance the high-grade opportunities at Brimstone and Vortex while also supporting geophysics, geochemistry, and other step out exploration in newly identified target areas east of Brimstone, including the Manganese target.  The Program aims to extend these systems along dip and along strike as both systems remain open in all directions and at depth. Crews are mobilized, and drilling is scheduled to commence in early August.
The 2025-2026 Exploration Drill Program builds on the successes of the 2023 and 2024 Drill Programs which led to the discovery of the two high-grade silver systems at Brimstone and Vortex.  That drill program delivered two of the best holes ever drilled in Hycroft’s more than 40-plus year operating history. Drill results demonstrated significant high-grade silver mineralization grading several hundred grams/tonne silver including intervals in the several thousand grams/tonne silver (>11,000 g/t Ag). Following the 2024 Drill Program, the exploration team analyzed the results, conducted additional geophysics work, and further refined the mineralization and structural controls of the high-grade systems.  This work became the foundation for selecting targets for the 2025-2026 Exploration Program.
Alex Davidson, Vice President, Exploration, said, “Data from the 2023 and 2024 Drill Programs has provided multiple target horizons in both Brimstone and Vortex. The multiple overlapping mineralizing events at both Brimstone and Vortex bringing significant metal into these deposits, is what has shaped our 2025-2026 drill program.  From the data we learned that the high-grade silver at Brimstone is the result of an intermediate sulfidation system which is uniquely different from the rest of the Hycroft mineralization.  In Vortex, the high-grade silver is related to pre-mineral low-angle structural preparation.  This new understanding of structure and intrusive trends defined by geochemical associations, geophysics and field mapping has been integrated into a new cohesive geologic model that is also being applied to our exploration efforts, not just in the Brimstone and Vortex area but east of Brimstone and throughout the rest of the Hycroft district.  The targets for the 2025-2026 Exploration Drill Program have been developed through extensive review of our data within the new model.”
Diane Garrett, President and CEO, said, “Our first-principles approach at Hycroft has led us to understand the controls driving the Hycroft system in a new way, resulting in the spectacular results we achieved in 2023 and 2024 and opening up new prospective targets previously not identified.  Now, in 2025, we will continue to build on these findings to explore, define, and aggressively pursue the growth potential of the high-grade Brimstone and Vortex systems.  We believe the significance and importance of silver at Hycroft was previously overlooked, as silver represents a substantial and previously underappreciated source of potential future revenue at the Hycroft Mine.  Our team’s ongoing work is unlocking significant value for shareholders as we continue to uncover the full potential of this world-class asset. I also want to recognize our team for their incredible commitment to ensuring the health and safety of our employees and anyone who comes to the mine site. In addition to our exploration and development activities, we maintain a full mine site with heavy machinery, numerous on-site contractors as well as daily monitoring and maintenance activities. Safety is the number one priority at every stage of a mining project,  and I commend the Hycroft team for always leading with this commitment. As of mid-2025, I am proud to announce that we concluded more than two and a half consecutive years with a Total Reportable Injury Frequency Rate of 0.00. With drilling ramping up on our high-grade silver targets and engineering studies in full swing, safety remains front and center for the entire Hycroft team. This strict adherence to safety discipline and culture within Hycroft will serve us well as we transition to the next phase of operations.”
