[{"type":"text","content":" Highest grades to date identified in Vortex Multiple intercepts grading 960 g/t to 1545 g/t New target areas for expansion WINNEMUCCA, Nev., Dec. 22, 2025 /PRNewswire/ -- Hycroft Mining Holding Corporation (Nasdaq: HYMC) (\"Hycroft\" or \"the Company\") announces drill results from the 2025-2026 Exploration Drill Program (the \"Exploration Program\") at the Hycroft Mine, located in Nevada, USA a Tier-1 mining jurisdiction. Highlights from the drilling include: Highest grades to date identified in Vortex Vortex expands approximately 70 meters to the northwest and approximately 90 meters down-dip to the west based on results from H25D-6070 and H25D-6072 Results confirm continuity of high-grade silver Vortex remains open in all directions and at depth Vortex drill highlights: H25D-6072: 26.4 meters at 565.31 g/t Ag and 0.46 g/t Au (604.92 g/t AgEq and 7.02 g/t AuEq)Including: 6.9 meters at 802.96 g/t Ag and 0.62 g/t Au (856.35 g/t AgEq and 9.94 g/t AuEq) Multiple intercepts grading 960 g/t Ag to 1545 g/t Ag Announced Dec. 15, 2025: H25D-6070: 30.8 meters at 438.58 g/t Ag and 0.41 g/t Au (473.88 g/t AgEq and 5.50 g/t AuEq)Including: 6.1 meters at 739.58 g/t Ag and 0.21 g/t Au (757.66 g/t Ag Eq and 8.79 g/t AuEq) Alex Davidson, Vice President, Exploration commented: \"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. Figure 1 demonstrates the direction of this newly identified mineralization which is being compiled into the database and new images are forthcoming. Both Brimstone and Vortex high-grade silver systems are structurally controlled, and mineralization extends across these structural faults. Additional opportunities for expansion are open along and within these structures.\" Hole ID FROM TO INTERVAL GRADE (meters) (meters) (meters) Ag (g/t) Au (g/t) AgEQ(g/t) AuEQ (g/t) Vortex H25D-6072 408.6 435.0 26.4 565.31 0.46 618.96 7.02 Including 426.5 433.4 6.9 802.96 0.62 856.35 9.94 Diane Garrett, Presi...
