8-K: Hycroft Mining Launches Major 2025-2026 Exploration Drill Program Targeting High-Grade Silver

Hycroft Mining Holding Corporation announces the imminent start of its 2025-2026 exploration drill program at the Hycroft Mine in Nevada, focusing on expanding high-grade silver systems.

Summary

• Hycroft Mining Holding Corporation is initiating its 2025-2026 Exploration Drill Program at the Hycroft Mine, located in Nevada, USA, a Tier-1 mining jurisdiction.
• The program will comprise approximately 14,500 meters of core drilling utilizing two drill rigs.
• Drilling is scheduled to commence in early August.
• The program is designed to expand and advance high-grade opportunities at Brimstone and Vortex, and to support geophysics, geochemistry, and other step-out exploration in newly identified target areas east of Brimstone, including the Manganese target.
• This program builds on the successes of the 2023 and 2024 Drill Programs, which led to the discovery of two high-grade silver systems at Brimstone and Vortex.
• Previous 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).

• Commercial success of, and risks related to, exploration and development activities.
• Uncertainties and risks related to reliance on contractors and consultants.
• Availability and cost of equipment, supplies, energy, or reagents.
• The exploration target is conceptual and does not represent a mineral resource or reserve; further exploration may not result in the estimation of a mineral resource.
• Actual results, performance, or achievements may differ materially from forward-looking statements.

Future Outlook

The company plans to continue building on previous findings to explore, define, and aggressively pursue the growth potential of the high-grade Brimstone and Vortex systems. Management believes silver represents a substantial and previously underappreciated source of potential future revenue at the Hycroft Mine, with ongoing work aimed at unlocking significant value for shareholders and uncovering the full potential of this world-class asset.

Management Comments

• Alex Davidson, Vice President, Exploration: "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: "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 teams ongoing work is unlocking significant value for shareholders as we continue to uncover the full potential of this world-class asset."
• Diane Garrett, President and CEO: "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."

Industry Context

This announcement reflects a common strategy in the mining industry where companies with large land packages conduct exploration programs to expand known resources and discover new deposits, especially after successful initial drilling. The focus on high-grade silver is notable given the increasing demand for precious metals. Operating in a Tier-1 jurisdiction like Nevada reduces geopolitical risk compared to other mining regions, enhancing project stability and attractiveness.

Comparison to Industry Standards

• The discovery of high-grade silver mineralization grading several hundred grams/tonne silver, including intervals in the several thousand grams/tonne silver (>11,000 g/t Ag), is exceptionally high-grade for silver deposits globally. Many primary silver mines consider grades of 100-300 g/t Ag to be good, while grades over 1,000 g/t Ag are considered bonanza grades.
• The company's achievement of a Total Reportable Injury Frequency Rate of 0.00 for over two and a half consecutive years as of mid-2025 represents a strong safety performance, often exceeding industry averages for active mine sites.
• The 14,500 meters of core drilling with two rigs is a substantial program for an exploration-focused company, indicating a significant commitment to resource expansion and development.

Stakeholder Impact

• Shareholders: Potential for increased share value due to the discovery and expansion of high-grade resources, leading to future revenue and unlocking significant value.
• Employees: Continued employment and a strong emphasis on health and safety, as evidenced by the company's excellent safety record.
• Contractors (Timberline Drilling, Alford Drilling, ALS Geochemical): Continued business and engagement for drilling and assay services.

Next Steps

• Commencement of the 2025-2026 Exploration Drill Program in early August.
• Continued exploration, definition, and aggressive pursuit of growth potential at the high-grade Brimstone and Vortex systems.
• Ongoing analysis of drill results and refinement of geological models.
• Completion of technical studies to transition the Hycroft Mine into a large-scale milling operation for processing sulfide ore.

Key Dates

Recommendation

The announcement of a substantial exploration program targeting high-grade silver, building on previous bonanza-grade discoveries, signals significant potential for resource expansion and future value creation. The company's new geological understanding and focus on silver as a key value driver, combined with a strong safety record in a Tier-1 jurisdiction, make this a compelling investment opportunity for long-term growth. The explicit mention by management of unlocking "significant value for shareholders" further reinforces a positive outlook.
