Hycroft Mining Holding Corp. Delivers More High-Grade - Expands New Silver System at Brimstone

Highlights from the drilling include:

• Confirmation of well-developed veins with very high-grade silver.
• The new Brimstone silver system is strong in continuity, extending more than 800 meters in strike and remains open.
• Evaluation of results from the Drill Program reveals two new trends with continuous high-grade silver greater than 137 g/t (see Figure 2):
  • A northwest trend extending from Vortex to Camel (> 600 meters strike).
  • A northeast trend extending from Vortex to Brimstone (> 800 meters strike).
  • Both trends are open along strike and additional drilling is expected to demonstrate that these trends intersect.

Brimstone drill highlights:

• H23C-5790: 20 meters of 869.9 g/t Ag and 0.40 g/t Au
  • Including 7 meters of 2,427.03 g/t Ag and 0.39 g/t Au
• H23R-5782: 52 meters of 74.49 g/t Ag and 0.40 g/t Au
  • Including 13 meters of 211.60 g/t Ag and 0.59 g/t Au
• H23C-5795: 85 meters of 75.23 g/t Ag and 0.25 g/t Au
  • Including 10 meters of 373.86 g/t Ag and 0.31 g/t Au
• H23R-5761: 6.1 meters of 451.85 g/t Ag and 0.18 g/t Au
  
  
• H23R-5775: 64 meters of 24.84 g/t Ag and 0.45 g/t Au
  • Including 9 meters of 107.72 g/t Ag and 0.57 g/t Au

Alex Davidson, Vice President, Exploration commented: "These recent silver assay results are very exciting as they continue to define and expand the recently discovered high-grade silver trend in Brimstone. Evaluation of high-grade silver results from 2023 in both Brimstone and Vortex in conjunction with existing drilling and geophysics has defined two significant silver trends; the Vortex-Brimstone and Vortex-Camel trends, striking northeast and northwest, respectively, as shown in Figure 2. Both trends have continuous high-grade silver greater than 137 g/t with areas of very high-grade silver (> 2000 g/t) in well-defined veins. The new concepts developed during the 2023 drilling, supported by reported results from H23C-5790 and H23C-5795, will be used to better vector targeting in 2024 as we continue to develop these high value areas."

The Company is hosting a webinar to discuss the Drill Program results in greater detail on Thursday, January 11, 2024, at 12:00PM ET/9:00AM PT. For event details and to register visit: https://events.6ix.com/preview/developing-the-hycroft-mine.

Corporate Update

The Company's unrestricted cash balance was $106.1 million at December 31, 2023. On January 5, 2024, the Company reduced its senior secured debt with Sprott Resource Lending ("Sprott") by $38 million, leaving an unrestricted cash balance of approximately $66 million. The remaining principal balance of that facility totals $15 million and the associated interest rate was reduced by 100 basis points.

Diane R. Garrett, President & CEO, commented: "The drill program executed over the last two years has delivered results confirming our theory that there is much more to Hycroft than the historically perceived low-grade disseminated orebody. Hycroft boasts one of the largest gold and silver deposits in the world. With these results we are starting to understand that silver is a huge value driver for the Hycroft Mine and our plans for re-starting operations. We are very encouraged by these results and plan to accelerate the next phase of drilling to further home in on the potential of these new high-grade silver discoveries and their impact on the economics of the project."

Ms. Garrett continued: "Our primary objective is to deliver exceptional value to our shareholders. From the start, we set out to do so by building a solid foundation for the next phase of operations and maintaining a strong balance sheet. As part of this commitment, we recently reduced our debt with Sprott, and the team's exceptional efforts are yielding strong results not only in exploration but also with the engineering studies that are of critical importance. We have a lot in store for the year ahead and look forward to sharing those results with the market as we uncover Hycroft's true potential."

About the 2022-2023 exploration drill program

The drill program is designed to improve the understanding of the higher-grade intercepts, better understand the mineralization controls, and test exploration targets outside the currently known resource. Through this work the Company hopes to develop opportunities to mine higher-grade ore early in the mine plan, thereby enhancing the project's economics. In Phase 2 of the Drill Program, a total of 11,100 meters of RC drilling and 6,00 meters of core drilling were completed. The RC drilling for Phase 2 was conducted by Boart Longyear of West Valley City, UT, and Alford Drilling of Elko, NV, and core drilling for Phase 2 is being conducted by Timberline Drilling Incorporated of Elko, NV. Assays are being completed by Paragon Geochemical of Reno, NV. The Company's Qualified Person is Alex Davidson, Vice President, Exploration.
