NEWS RELEASE
Vortex and Brimstone Continue to Expand With Higher Grades
Vortex returns 30.5 meters at 780.53 g/t silver and 6.1 meters at 21.12 g/t gold
Brimstone extends north with 5.5 meters at 1,345.27 g/t silver
WINNEMUCCA, NV, September 9, 2026 – Hycroft Mining Holding Corporation (Nasdaq:
HYMC) (“Hycroft” or “the Company”) announces additional drill results from the 2025-2026
Exploration Drill Program (the “Drill Program”) at the Hycroft Mine, located in Nevada, USA, a
Tier-1 mining jurisdiction.
Vortex Drill Highlights:
• H26D-6090: 30.5 meters at 780.53 g/t silver and 0.49 g/t gold
o Including 11.2 meters at 1,664.80 g/t silver and 0.85 g/t gold
o Also including 5.5 meters at 2,249.39 g/t silver and 1.01 g/t gold
• H26D-6166: 20.0 meters at 460.82 g/t silver and 0.32 g/t gold
o Including 6.1 meters at 952.37 g/t silver and 0.54 g/t gold
o Also including 1.6 meters at 2,650.00 g/t silver and 0.91 g/t gold
• H26D-6172: 6.1 meters at 28.65 g/t silver and 21.12 g/t gold
o Including 1.5 meters at 49.40 g/t silver and 43.00 g/t gold
Brimstone Drill Highlights:
• H26D-6167A: 5.5 meters at 1,345.27 g/t silver and 0.56 g/t gold
o Including 1.8 meters at 4,074.00 g/t silver and 1.43 g/t gold
Diane Garrett, Executive Chairman and CEO, commented: “These are some of the strongest
results we’ve seen from the Drill Program. We’re not just confirming the high-grade silver system,
we’re extending it and are consistently intersecting thick, continuous, high-grade mineralization.
We have also intersected a high-grade gold interval higher in the known system that we intend to
follow up on as we are seeing an increasing number of higher-grade gold intercepts in this area of
Vortex. These results continue to confirm our exploration strategy and underpin the potential for
a high-grade underground mine. With the system open in all directions and at depth, we see a
clear opportunity for continued expansion and growth of these high-grade mineralized systems.”

Vortex Results
Hole H26D-6090 and H26D-6166 returned 30.5 meters at 780.53 g/t silver and 20.0 meters at
460.82 g/t silver, respectively. Both were drilled offsetting H25D-6070 and H25D-6072 and
connect that 2025 step-out drilling to the main Vortex trend. Mineralization remains open to the
west, down dip along the Central and Albert faults, currently interpreted as two of the more
productive feeder structures at Vortex, and to the north and south.
Holes H26D-6172 tested the northern flank of Vortex and hit four separate silver intervals down
hole in the footwall of the Break fault: 23.0 meters at 137.23 g/t silver and 0.69 g/t gold, 12.3
meters at 112.91 g/t silver and 0.25 g/t gold, 21.7 meters at 121.94 g/t silver and 0.89 g/t gold,
and 11.1 meters at 177.97 g/t silver and 0.62 g/t gold, demonstrating the vertical continuity and
extent of Vortex in this area.
H26D-6173, drilled down dip to the west of H26D-6172, returned 7.4 meters at 134.13 g/t silver,
including 2.7 meters at 284.05 g/t silver, and 6.1 meters at 33.99 g/t silver and 2.63 g/t gold.
These results further extend the high-grade continuity along the northern flank of the system.
Hole H26D-6172 also returned a high-grade gold interval higher in the hole, 6.1 meters at 21.12
g/t gold, including 1.5 meters at 43.00 g/t gold. This intercept lies higher in the Vortex high-grade
silver system. With an increasing number of higher-grade gold intercepts in this area, the
Company is planning follow-up drilling to determine the orientation and extent of this
mineralization and whether it represents a separate high-grade gold system.

Brimstone Results
At Brimstone, the strategy is to develop the high-grade stockwork vein zone, test the controls on
mineralization to the north, south and down dip, and identify and develop high-grade
opportunities. Hole H26D-6167A was designed to test and extend high-grade mineralization to
the north. The hole encountered a 30-meter silicified breccia that hosted high-grade silver,
intersecting 5.5 meters at 1,345.27 g/t silver, including an impressive 1.8 meters at 4,074.00 g/t
silver. This intercept opens up additional target opportunities and follow-up drilling is being
planned.

This press release contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of
1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities
Litigation Reform Act of 1995. All statements, other than statements of historical fact, included in this press release
and in public statements by our officers or representatives that address activities, events or developments that we
expect or anticipate will or may occur in the future are forward-looking statements. These include, but are not limited
to, statements regarding future business strategy, plans and goals, competitive strengths, the advancement and
development of the Hycroft Mine, the results and implications of metallurgical analysis and test work, and the
expansion and growth of our business.
Forward-looking statements are often identified by future or conditional words such as "estimate," "plan," "anticipate,"
"expect," "intend," "believe," "target," "budget," "may," "can," "will," "would," "could," "should," "seeks," "scheduled
to" and similar words or expressions but the absence of these words does not mean that a statement is not forward-
looking. Forward-looking statements are based on current expectations, estimates and projections that involve a
number of risks and uncertainties, which could cause actual results to differ materially from those reflected in the
statements. The risks include, but are not limited to: (i) risks related to changes in our operations at the Hycroft Mine,
including risks associated with the cessation of mining operations at the Hycroft Mine; uncertainties concerning
estimates of mineral resources; risks related to the lack of a completed feasibility study; risks related to metallurgical
test work and process development; and risks related to our ability to re-establish commercially feasible mining and
processing operations; and (ii) industry-related risks, including fluctuations in the price of gold and silver; the
commercial success of, and risks related to, our exploration and development activities; uncertainties and risks
related to our reliance on contractors and consultants; and the availability and cost of equipment, supplies, energy or
reagents.
Any exploration target described in this press release does not represent, and should not be construed to be, an
estimate of a mineral resource or mineral reserve. Ranges of potential tonnage and grade (or quality) of an exploration
target are conceptual in nature; there has been insufficient exploration of the relevant property or properties to
estimate a mineral resource; and it is uncertain if further exploration will result in the estimation of a mineral resource.
These and other risks may cause actual results to differ materially from those expressed or implied by the forward-
looking statements, and the occurrence of one or more of these events or circumstances, alone or in combination with
others, may have a material adverse effect on our business, cash flows, financial condition and results of operations.

as anticipated, estimated or intended. Although these forward-looking statements are based on assumptions that we
believe are reasonable when made, forward-looking statements are not guarantees of future performance and actual
results, performance or achievements may differ materially from those made in or suggested by the forward-looking
statements in this press release.
Any forward-looking statements made in this press release speak only as of the date of this press release. We
