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

In This Article:

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.
