Risks

• Risks related to changes in operations at the Hycroft Mine, including uncertainties associated with the cessation of mining operations.
• Uncertainties concerning estimates of mineral resources.
• Risks related to the lack of a completed feasibility study for the mine.
• Risks related to metallurgical test work and process development.
• Risks related to the company's ability to re-establish commercially feasible mining and processing operations.
• Fluctuations in the price of gold and silver.
• Risks associated with the commercial success of exploration and development activities.
• Uncertainties and risks related to reliance on contractors and consultants.
• Availability and cost of equipment, supplies, energy, or reagents.
• Exploration targets are conceptual in nature and do not represent mineral resources or reserves; further exploration may not result in the estimation of a mineral resource.

Future Outlook

The company's 2025-2026 exploration strategy is focused on unlocking the full scale of the Vortex and Brimstone high-grade silver systems through both lateral and depth expansion. Management anticipates many more results to come, indicating the company is at the very beginning of a pivotal growth phase. Additionally, the company is focused on completing technical studies to transition the Hycroft Mine into a large-scale milling operation for processing sulfide ore.

Management Comments

• "H25D-6072 was designed to offset H25D-6070 by approximately 65 meters to the northwest. Hole 6072 extends Vortex mineralization an additional 35 meters to the west of the intercept in Hole 6070. Hole 6072 combined with the recently disclosed Vortex hole 6070 clearly demonstrate that Vortex is returning longer intercepts of very high grades and the system remains open in all directions and at depth." Alex Davidson, Vice President, Exploration.
• "Our 2025-2026 exploration strategy is focused on unlocking the full scale of the Vortex and Brimstone high-grade silver systems through both lateral and depth expansion these latest impressive results clearly demonstrate there is much more potential to both systems." Diane Garrett, President and CEO.
• "Step-out drilling 75 meters west (Hole 6070 announced on Dec. 15, 2025), followed by a further step-out of 35 meters northwest (Hole 6072), represents a meaningful advance in scale and confirms not only exceptional silver grades but increasing continuity within this system." Diane Garrett, President and CEO.
• "Vortex and Brimstone are emerging as two high-grade silver systems of significant size and consistency – an evolution that is fundamentally reshaping Hycroft’s value proposition." Diane Garrett, President and CEO.
• "With these results and many more expected to come, we are at the very beginning of a pivotal growth phase." Diane Garrett, President and CEO.
• "While we don’t typically issue results on single drill holes – these recent two holes in Vortex, when viewed together, represent something extremely significant occurring." Diane Garrett, President and CEO.

Industry Context

The Hycroft Mine is situated in Nevada, a recognized Tier-1 mining jurisdiction, which offers a stable and favorable environment for mineral exploration and development. The reported high-grade silver and gold discoveries, coupled with the expansion of the Vortex system, are significant for the precious metals industry. Such high-grade results can enhance a company's resource base, improve project economics, and attract investor interest, especially as companies globally seek to secure and expand their precious metal reserves amidst market fluctuations.

Comparison to Industry Standards

• The filing highlights the 'highest grades to date identified in Vortex,' which serves as a strong internal benchmark for the company's exploration success within its own project.
• While no specific comparable companies or projects are named, high-grade silver intercepts of 960 g/t to 1545 g/t Ag are considered exceptional within the global silver mining industry, often exceeding average grades of many producing silver mines.

Stakeholder Impact

• Shareholders: Highly positive impact due to significant high-grade discoveries and expansion, potentially increasing the company's intrinsic value and future share price.
• Employees: Positive outlook with continued and potentially expanded exploration and development activities, ensuring job security and growth opportunities.
• Customers: Not directly impacted at this exploration stage, but successful development could lead to future precious metal supply.
• Suppliers/Creditors: Increased demand for drilling contractors, assay labs, and other mining-related services. Creditors may view the company as a stronger investment due to enhanced asset potential and future cash flow prospects.

Next Steps

• Compilation of newly identified mineralization into the database and creation of new images.
• Continuation of the 2025-2026 Exploration Drill Program, with an initial 14,500 meters of core drilling.
• Planned addition of two core rigs in 2026 to further accelerate the exploration program.
• Completion of technical studies to transition the Hycroft Mine into a large-scale milling operation for processing sulfide ore.
• Further exploration drilling to unlock the full potential of the expansive +64,000-acre land package, of which less than 10% has been explored.

Key Dates

Recommendation

The drill results indicate exceptionally high-grade silver and gold intercepts, with significant expansion of the Vortex system, which remains open in all directions and at depth. This suggests substantial untapped potential and could fundamentally reshape the company's value proposition. Such discoveries in a Tier-1 jurisdiction like Nevada are highly attractive to investors, signaling a pivotal growth phase and strong future prospects for resource definition and potential development, warranting a strong buy recommendation.
