Multiple zones of higher-grade silver encountered
Higher gold and silver grades than resource average grade
Higher grade zones more continuous than previously interpreted

WINNEMUCCA, NV, September 13, 2022 - Hycroft Mining Holding Corporation (Nasdaq: HYMC) (“Hycroft” or the “Company”), a gold and silver development company which owns the Hycroft Mine in the prolific mining region of Northern Nevada, is pleased to announce initial drill results from its 2022-2023 exploration program.

Highlights of the initial results from our reverse circulation (“RC”) drilling are noted below (grams / metric ton “g/t”). Full results received to date are reflected in Table 1 below.

• Hole 22R-5650 returned 82 meters of 1.03 g/t gold and 30.38 g/t silver
  • Including 3 meters of 1.20 g/t gold and 163.51 g/t silver
• Hole 22R-5647 returned 58 meters of 0.58 g/t gold and 24.07 g/t silver
  • Including 5 meters of 0.65 g/t gold and 171.02 g/t silver
• Hole 22R – 5644 returned 50 meters of 0.79 g/t gold and 38.74 g/t silver
  • including 5 meters of 2.23 g/t gold and 84.69 g/t silver
• Hole 22R-5645 returned 20 meters of 0.10 g/t gold and 90.86 g/t silver
  • and 34 meters of 3.77 g/t gold and 16.77 g/t silver

Alex Davidson, Vice President, Exploration commented, “These initial drill results confirm the higher-grade opportunities identified in the 2021 drill program. While we have only just begun investigating the planned targets of our 2022-23 drill program, these results are very encouraging and further confirm the importance of additional drilling to explore the untapped potential of the Hycroft deposit. Importantly, we are observing the high-grade zones are more continuous than previously interpreted in addition to seeing silver and gold grades significantly higher than the average grade at the Hycroft deposit.”

In addition to the two RC rigs drilling in the Brimstone and Central areas, the core rig is currently drilling the deeper areas of the Hycroft system, primarily at the high-grade silver Vortex area. In our first core hole we are seeing silicification, banded silica veining, sulfide stockwork along with white clays among other key indicators in the core.

We are currently following up on high grade intercepts within the resource area and plan to begin targeted step-out drilling in the fourth quarter within the more than 60,000 acres that has not previously been explored.

We recently completed a hyperspectral flyover of the entire Hycroft property (70,000 acres). This imaging technology has important applications in our type of deposit. Hyperspectral imaging helps identify potential minerals or deposits of minerals and allows companies to hone-in on specific areas for drilling. The geophysical studies indicate near vertical strong silicification. This information will help guide our upcoming surface mapping and soil sampling program to further define our large unexplored land package.

Higher grade zones more continuous than previously interpreted

While the initial drill locations have been focused on improving our understanding and ability to project high-grade zones, additional drill targets are designed to test:

• prospective target areas near the current resource;
• expansion of the current resource along strike and at depth;
• targets identified through our recent geophysical work within our 60,000 acres that have never been explored; and
• targets in areas with limited historical drilling.

The results of this exploration program, together with the 2021 metallurgical drill program results will be used for the geologic modelling, updated resource models and mine planning activities associated with the technical studies underway for the sulfide mill operation.

Diane R. Garrett, President & CEO commented “We are very excited about these initial drill results and still have so many targets yet to drill. This supports our belief that there remains untapped potential at Hycroft. With the largest exploration program in nearly a decade, we are the first company to systematically explore this world-class system to understand the genesis of this deposit, including potential feeder systems. Hycroft is one of the largest gold and silver deposits in the world located in the Tier-One mining jurisdiction of Nevada, USA and permitted for both heap leach and milling operations. “

About the 2022-2023 exploration program

The 2022 – 2023 exploration program at the Hycroft Mine comprises approximately 100,000 feet of reverse circulation drilling and approximately 25,000 feet of core drilling. The RC drilling is being conducted by National EWP Inc. of Elko, NV and the core drilling is being conducted by First Drilling LLC of Montrose, CO. Assays are being completed by Bureau Veritas and Paragon Geochemical of Reno, NV. The Company’s Qualified Person is Mr. Alex Davidson, Vice President, Exploration.
