[{"type":"text","content":" Highest grades to date identified in Vortex New target areas for expansion Corporate Update WINNEMUCCA, Nev., Dec. 15, 2025 /PRNewswire/ -- Hycroft Mining Holding Corporation (Nasdaq: HYMC) (\"Hycroft\" or \"the Company\") announces initial 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.   A corporate update on technical studies and new resource are also announced. Highlights from the drilling include: Highest grades to date identified in Vortex Vortex expands over 75 meters to the west and opens targets to the north and south Results confirm continuity of high-grade Vortex remains open both down dip and along dip Vortex drill highlights: H25D-6070: 30.8 meters at 438.58 g/t Ag and 0.41 g/t Au (5.48 g/t AuEq) Including: 6.1 meters at 739.58 g/t Ag and 0.21 g/t Au (8.79 g/t AuEq) Alex Davidson, Vice President, Exploration commented: \"I am very excited to announce the first results of the 2025-2026 Exploration Drill Program designed to follow up on the successes of the 2024 drill program at both Brimstone and Vortex.  The intercepts in Hole H25D-6070 are very significant as this represents the highest silver grades with the longest continuous intercept we have seen in Vortex thus far.  This intercept extends high-grade mineralization down dip to the west approximately 75 meters from the farthest hole drilled in the 2024 program and opened up areas of opportunity to the north and south that currently have no drilling.  The first hole completed this year was H25D-6068 and was drilled 200 meters east of H25D-6070.  It was designed to test the footwall of the Albert fault intersection of the high-grade silver trend. While the results did not return the grade of mineralization we typically see in Vortex, there is strong mineralization over 169 meters that indicates we are still within a very remarkable mineralized zone, requiring further exploration in this part of the deposit.  See additional details below. Drilling at Brimstone and Vortex Drilling is well underway on the high-grade silver systems at both Brimstone and Vortex. The current drill program began at Vortex while the Company was completing geophysics at Brimstone to refine drill targets.&nb...
