WINNEMUCCA, Nev., Nov. 16, 2023 /PRNewswire/ -- Hycroft Mining Holding Corporation (Nasdaq: HYMC) ("Hycroft" or "the Company") is pleased to announce the latest drill results from its ongoing 2022-2023 exploration drill program (the "Drill Program") at the Hycroft Mine, located in Nevada, a Tier-1 mining jurisdiction. Drilling focused on the existing Brimstone pit, which has long been known as only a disseminated gold deposit. The new drill results identified a new system of significant quartz veining containing very high-grade silver mineralization spanning 300 meters in strike length and remains open along strike. Additional assays are pending from follow-up core drilling in this area.

Results were received for three of the holes drilled comprising reverse circulation ("RC") and core holes: H23R-5753, H23R-5760, and H23R-5771. Key highlights include:

Discovery of a new silver system at Brimstone as a result of applying a fresh perspective and following up on targets not previously tested.
H23R-5753 is Hycroft's best hole ever drilled in its more than 30-year history and is confirmed with additional follow-up core drilling.
Results, when compiled with the rest of the Drill Program, indicate the presence of more significant silver mineralization than previously understood at the Hycroft Mine.

Brimstone drill highlights:

RC hole H23R-5753 returned 85.3 meters of 534 g/t Ag and 0.23 g/t Au
- Including 39.6 meters of 1,019 g/t Ag and 0.26 g/t Au
- Including 4.6 meters of 4,974 g/t Ag and 0.56 g/t Au
RC hole H23R-5760 returned 131.1 meters of 213 g/t Ag and 0.34 g/t Au
- Including 41.1 meters of 636 g/t Ag and 0.47 g/t Au
- Including 12.2 meters of 1,554 g/t Ag and 0.48 g/t Au
Core hole H23R-5771 returned 152.9 meters of 143 g/t Ag and 0.32 g/t Au
- Including 57.7 meters of 357 g/t Ag and 0.29 g/t Au
- Including 4.2 meters of 3,807 g/t Ag and 0.58 g/t Au

Diane Garrett, President and CEO commented: "Our team has taken a fresh view of Hycroft, leveraging our history of successfully studying data, reinterpreting geology, and looking for new opportunities in under-explored areas. With our knowledge of the drivers for high-grade mineralization, we identified a new high-grade silver system within Hycroft that we will continue to follow along strike with additional drilling. These results confirm our belief that there is so much more to Hycroft. Even after its long history, we believe Hycroft remains an untold story."

Commenting on the results, Alex Davidson, VP of Exploration for Hycroft, stated: "These results represent a significant milestone of a new high-grade silver system being discovered at Brimstone. Drilling to date confirms a 300-meter strike length of high-grade silver in banded veining and the association of silver-bearing minerals. The drilling at Brimstone supports our understanding that silver mineralization is vein-controlled and not disseminated. In addition, this system is much shallower than the high-grade silver system at Vortex. These drill results also confirm the northern extension of a previously identified geophysics anomaly at Vortex, indicating possible continuity between the two zones."

Observations made during logging of RC holes H23R-5753 and H23R-5760 show an association between quartz veining and silver-bearing sulfides. To provide better definition, the remaining holes were drilled as core holes. Detailed logging of core hole H23R-5771 confirm vein width, density, orientation, and the association of these silver-bearing minerals. Assay results from these holes also confirm the logged geology. Full results received to date are reflected in Table 1.

These holes, combined with additional drilling in the Brimstone area, are defining a trend of silver mineralization associated with northeast-trending high-angle quartz veins not previously recognized. Additional drilling is underway to continue defining this system.

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. The 2022-2023 exploration drill program at the Hycroft Mine comprises approximately 30,000 m of RC drilling and approximately 7,500 m of core drilling. 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.
