Hycroft Mining Finds Elevated Silver Across the Hycroft System in Phase 2 Drilling

WINNEMUCCA, Nev., Oct. 23, 2023 /PRNewswire/ -- Hycroft Mining Holding Corporation (Nasdaq: HYMC) ("Hycroft" or "the Company") announces interim drill results for the Camel and Vortex zones from Phase 2 of its 2022-2023 exploration drill program (the "Drill Program") at the Hycroft Mine. Drilling is ongoing and additional results are pending. Results to date are achieving the objectives of the Drill Program designed to improve continuity of the higher-grade intercepts, fine tune the sequencing of the mine plan, and for the first time in more than a decade, test exploration targets outside the currently known resource.

Highlights from the drilling include:

• The Hycroft system continues to expand with mineralization extending the Camel and Vortex zones.
• Vortex continues to deliver very high-grade silver at depth extending mineralization 300 meters to the west.
• More silver in the Camel zone than anticipated and higher silver grades near surface.
• Drill results from Vortex are 15 times higher than the average silver resource grade¹.

Vortex Drill Highlights (see Figure 1):

• H23C-5770: 51 m of 0.50 g/t Au and 139.87 g/t Ag
  • Including 18 m of 0.31 g/t Au and 288.83 g/t Ag
  • Including 11 m of 1.29 g/t Au and 138.48 g/t Ag
• H23C-5769: 60 m of 0.36 g/t Au and 75.91 g/t Ag
  • Including 18 m of 0.55 g/t Au and 211.89 g/t Ag

Camel Drill Highlights (see Figure 2 and Figure 3):

• H23R-5759: 204 m of 0.53 g/t Au and Ag
  • Including 41 m of 0.49 g/t Au and 75.81 g/t Ag
• H23R-5785: 49 m of 0.50 g/t Au and 43.60 g/t Ag
  • Including 12 m of 0.59 g/t Au and 161.16 g/t Ag
• H23R-5786: 75 m of 0.36 g/t Au and 41.20 g/t Ag
  • Including 30 m of 0.29 g/t Au and 106.01 g/t Ag
• H23R-5786: 52 m of 0.43 g/t Au and 44.99 g/t Ag
  • Including 8 m of 0.49 g/t Au and 266.72 g/t Ag

Alex Davidson, Vice President, Exploration, commented: "The Phase 2 program included two core holes following up on the success of previous drilling at Vortex and returned intervals 15 times greater than the average silver grade in the 2023 resource estimate¹. Both holes show continuity of high-grade silver connecting to the high-grade silver intercepts drilled in 2022 and extend this mineralization 300 meters west. Results from these holes indicate the high-grade silver mineralization will likely continue extending west towards Camel, potentially bridging the two zones."

In Figure 1 below, holes H23C-5770 and H23C-5769 were both core holes, of which H23C-5769 was drilled to confirm reverse circulation ("RC") drill hole H22R-5700 drilled in 2022. Through additional review of the data, the intercept at H22R-5700 now stands at 21 m of 685 g/t Ag versus the previously reported 55 m of 396 g/t Ag. The data demonstrates continuity of high-grade silver mineralization extending west. 

RC drilling in the Camel zone intercepted mineralization well outside the known resource cone (see Figure 2) as well as visible silver (see Figure 3). Silver mineralization was encountered in areas with limited silver assay data. These results are expected to have a positive impact on the resource model.

Mr. Davidson continued: "The Phase 2 drilling campaign in the Camel zone focused on converting inferred resources to measured or indicated and areas with limited drilling predominantly to the indicated category. We are very pleased with the results, which are higher grade than reflected in the current model. Particularly exciting are the significantly elevated silver grades near surface seen in the Camel zone, as well as grades that are higher than anticipated as these areas previously had limited assays for silver. These initial results will significantly help to enhance the economics for the 2024 pre-feasibility study. The drilling has extended mineralization to the south and indicates additional exploration potential exists south of the known resource." 

Commenting on the drill results, Diane Garrett, President & CEO, stated: "The increased amount of silver mineralization and higher grades observed at both Vortex and Camel are incredibly encouraging. While we know we already have a substantial silver resource at Hycroft, these findings provide further validation that Hycroft has a meaningful leverage to strong tailwinds we expect to see in the silver market fueled by the shift towards greener energy such as solar panels, and lower carbon technologies. It is clear that silver will play a pivotal role here, making our exploration efforts all the more promising."

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 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.
