Vortex Highlight:
| ● | Hole H26D-6175A: |
| ○ | 19.6 meters at 30.49 g/t gold and 1,726.72 g/t silver |
| ○ | Including 1.7 meters at 347.07 g/t gold and 9,526.36 g/t silver |
| ● | Visible gold present in the intercept |
| ● | Represents the best hole ever drilled in Hycroft’s more than 40-year history and the highest gold grades ever reported at Hycroft |
| ● | Highest silver grades ever drilled at Vortex |
| ● | This intercept extends farther to the west and south of previously reported high-grade gold and silver intercepts |
| ● | The style of alteration and mineralization could indicate proximity to a potential source of the Vortex system |
Diane Garrett, Executive Chairman and CEO, commented: “Hole H26D-6175A is an exceptional result and the best hole in our history. The silver-equivalent grade is more than 50% higher than that of our previous best hole, and this intercept contained the highest gold grades ever reported at Hycroft, with visible gold observed in the intercept. The combination of higher grades and longer intercepts suggests we may be getting close to a potential source of the Vortex system. Follow-up drilling is already underway and we look forward to accelerating the work at the Vortex and Brimstone systems.”

In addition to the high-grade gold and silver intercepts noted above, H26D-6175A also intersected significant intervals of gold and silver mineralization throughout the length of the hole, further enhancing the mineralization within the resource.
