Hycroft
Delivers $10 Billion NPV from Technical Report at Spot Prices

While
Advancing High-Grade Brimstone and Vortex Silver Discoveries

WINNEMUCCA,
NV, June 2, 2026 - Hycroft Mining Holding Corporation (Nasdaq: HYMC) (“Hycroft” or “the Company”),
is pleased to announce the results from its S-K 1300 Technical Report Summary and Initial Assessment (the “TRS”), which outlines
the economics and mine plan for a milling operation utilizing conventional pressure oxidation (“POX”) and heap leach processing
at the Hycroft Mine in Nevada, USA. All amounts are in US dollars, and all figures are presented in US customary units.

The
TRS demonstrates that Hycroft hosts a large-scale, long-life precious metals project with compelling economics and strong leverage to
rising gold and silver prices, reinforcing its position as a multi-generational, world-class asset in a Tier-1 jurisdiction. The TRS
is being filed concurrently with the SEC on EDGAR and is available on the Company’s website .

test work is pending as an alternative processing option which could potentially enhance
project economics including potentially adding a meaningful third revenue stream from the
by-product production and sale of sulfuric acid, a strategically important industrial chemical

Diane
R. Garrett, Executive Chairman and Chief Executive Officer, commented: “This Technical Study confirms the scale, quality, and long-term
potential of the Hycroft Mine. The project delivers strong economics and significant leverage to rising gold and silver prices, reinforcing
Hycroft’s position as one of the sector’s most compelling large-scale development opportunities, located in a Tier 1 jurisdiction.

(3)
Cash costs consist of mining costs, processing costs, mine-level G&A, and refining charges and royalties

(4)
All-in sustaining costs includes cash costs plus sustaining capital and closure costs

Cautionary
Statements Regarding the Initial Assessment and Mineral Resources

The
Initial Assessment is a preliminary technical and economic study that indicates the economic potential of the mineralization to support
the disclosure of mineral resources at the Hycroft Mine. The Initial Assessment, however, does not represent a feasibility study or a
pre-feasibility and does not demonstrate economic viability nor does it support a development decision, for which additional project
planning and design are needed. As a result, Hycroft plans to continue to estimate its resources at the Hycroft Mine and further develop
the project economics.

As
used in this news release, the terms “pre-feasibility study,” “feasibility study,” “initial assessment,”
“mineral reserve,” “mineral resource,” “measured mineral resource,” “indicated mineral resource”
and “inferred mineral resource”, as applicable, and other terms used herein are defined and used in accordance with S-K 1300.

The
Initial Assessment also does not include the conversion of mineral resources to mineral reserves. Under subpart 1300 of Regulation S-K,
mineral resources may not be classified as “mineral reserves” unless the determination has been made by a QP that the mineral
resources can be the basis of an economically viable project. Investors are specifically cautioned not to assume that any part or all
of the mineral deposits (including any mineral resources) in these categories will ever be converted into mineral reserves, as defined
by the SEC.

In
addition, estimates of inferred mineral resources have too high of a degree of uncertainty as to their existence and may not be converted
to a mineral reserve. Therefore, investors are cautioned not to assume that all or any part of an inferred mineral resource exists, that
it can be the basis of an economically viable project, or that it will ever be upgraded to a higher category. Likewise, investors are
cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted to mineral reserves.

Cautionary
Note Regarding Non-GAAP Financial Measures

Alternative
performance measures in this news release such as “cash cost”, “AISC”, and Free Cash Flow are furnished to provide
additional information. These non-GAAP performance measures are included in this news release because these statistics are used as key
performance measures that management uses to monitor and assess performance of the Hycroft Mine, and to plan and assess the overall effectiveness
and efficiency of mining operations. These performance measures do not have a standardized meaning within the accounting principles generally
accepted in the Unites States of America (“GAAP”) and, therefore, amounts presented may not be comparable to similar data
presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of
performance in accordance with GAAP.

Cash
Costs

Cash
costs include site operating costs (mining, processing, site G&A), refining charges and royalties (excludes corporate office G&A
and exploration expenses). While there is no standardized meaning of the measure across the industry, the Company believes that this
measure is useful to external users in assessing operating performance.

All-In
Sustaining Cost

Site
level AISC includes cash costs plus sustaining capital and closure costs. The Company believes that this measure is useful to external
users in assessing operating performance and the Company’s ability to generate free cash flow from potential operations.

Free
Cash Flow

Free
cash flows are revenues net of operating costs, royalties, capital expenditures, and cash taxes. The Company believes that this measure
is useful to the external users in assessing the Company’s ability to generate cash flows.

The
Hycroft Mine

The
Hycroft mine is among the world’s largest precious metals deposits. It is situated on the western flank of the Kamma Mountains
on the eastern edge of the Black Rock Desert approximately 54 miles west of Winnemucca in Humboldt and Pershing Counties, Nevada, a Tier-1
mining jurisdiction.

The
Technical Study is based on the 2026 Mineral Resource Estimate of 16.4 million ounces of gold and 562.5 million ounces of silver (measured
and indicated). An additional 5.0 million ounces of gold and 132.8 million ounces of silver exist in the inferred mineral resource category
which was not included in this study.

In
2023, Hycroft announced the discovery of two new high-grade silver systems within the known resource area and the Company is engaged
in a significant exploration drill program (2025-2026 drill program) designed to expand these two systems in addition to targeting newly
identified high-grade opportunities. These discoveries represent a significant value driver for the Hycroft Mine.

The
mine has existing facilities on site including administration buildings, mobile maintenance and light vehicle maintenance shops, warehouse,
leach pads, primary, secondary and tertiary crushing systems, assay lab, Merrill-Crowe process plants, refinery and components for a
larger second refinery.

Mining
Methods

Hycroft
is planned as a conventional hard rock open pit operation. The mine plan is based on measured and indicated mineralization that was estimated
in the mineral resource block model. Independent Mining Consultants developed a mine plan that produces the required process feed and
moves sufficient mine waste to assure continued release of the mineralization.

The
mine will feed two processing facilities:

1.

A
flotation mill followed by pressure oxidation and leaching of the concentrate, and

2.

A
Run-of-Mine (“ROM”) heap leach for mineralization that is amenable to direct
cyanide leaching.

The
cutoff grade for the schedule is based on income net of process:

●

Income
net of process = Net Return after Refining - Process Costs

Total
mined material begins with 11.3 million tons per annum in preproduction and increases to 71.2 million tons per annum in Years 1 through
3. Additional equipment is acquired later in the mine life with total material movement increasing to 82.0 million tons per annum from
Years 5 to 27. From Year 28 until the end of the mine life (Year 51) the total material mined reduces to 70 million tons per annum.

The
material planned for milling and leaching on the production schedule is potentially minable material. They do not constitute mineral
reserves at this time.

Low-grade
mill feed material is stockpiled throughout the mine life. This material is not fed to the mill and is not part of the economic analysis
in this report. Further trade-off studies will analyze the opportunity to feed this additional material through the process plant.

Processing
and Recovery Methods

A
significant portion of the gold and silver in the material going to the process plant is refractory due to its association with pyrite,
marcasite, and other sulfide minerals. Oxide and some transition material will be processed on a heap leach pad. A process flowsheet
was developed to treat sulfide and certain transition mineralization. These materials are ground and floated to produce a concentrate.
The concentrate is then oxidized in the POX plant and subsequently cyanide leached to extract gold and silver.

The
key process plant design criteria are:

●

Major
equipment is designed for a nominal throughput of 57,100 tons/day

●

process recovery of 82.8% gold and 77.5% silver, given the LOM average grades

●

Existing
crushing circuit consists of primary, secondary, and tertiary crushing, supported by a coarse
ore stockpile and a crushed ore stockpile with dedicated feeders to provide continuous feed
to the downstream process plant

●

Process
flowsheets include three stages of crushing followed by two stages of ball milling, flotation,
POX, a cyanide leaching circuit for oxidized flotation concentrate, Merrill-Crowe circuit,
and Tailings Management Facilities (“TMF”), with an overall availability of 92%

Pregnant
solution from the cyanide leach circuit will be processed in the existing Merrill-Crowe zinc cementation facilities.

Infrastructure

The
Hycroft Mine benefits from substantial existing infrastructure constructed and operated over decades of prior production. Key existing
facilities include:

●

Crushing
facility

●

Heap
leach pads

●

North
Merrill-Crowe facility

●

Onsite
access, haul roads and a major east-west railway pass adjacent to the Hycroft property

●

Truck
shop

●

Maintenance
building

●

Laboratory
and administrative buildings

●

Power
is supplied to the site from nearby power lines

●

Potable
water is sourced from a well

New
infrastructure to be constructed includes the Northeast TMF, a Waste Rock Storage Facility, the Process Plant Site and associated infrastructure,
a Limestone Plant, and a new rail spur.

The
proposed processing facility is designed to be inclusive with (or “of”) the existing crushing circuit and North Merrill-Crowe
facility. The proposed scope of work includes electrical distribution upgrades, new substations, process control systems, reagent handling
facilities (including oxygen and limestone systems), and selective expansion or repurposing of existing maintenance and administrative
buildings.

The
site currently has access to grid power. Additional transmission capacity is required to support the new plant. The total estimated load
factoring for load growth, including power for the oxygen plant, is 160 MW. Tie-ins to existing utilities will include water, compressed
air, and potable and sewer systems. The development of a freshwater production well field is also planned to support freshwater needs
throughout the LOM.

A
rail spur extension from the Union Pacific line is planned to support delivery of reagents, consumables, and fuel. Additionally, the
existing fuel island is to be replaced with a higher-efficiency system during the LOM.

Ancillary
structures including a covered crushed ore stockpile, new laboratory and maintenance facilities, fuel station upgrades, and technical
services expansion are proposed to support operations over the LOM. In addition to this, selected existing buildings will be relocated,
expanded, rehabilitated, or repurposed.

Contracts

Hycroft
Mine is subject to a royalty agreement (Sprott Royalty Agreement) with SPRL II which was initiated on May 29, 2020. The royalty is accounted
for by Hycroft as a deferred gain liability in which Hycroft received a cash consideration of US$30.0 million in exchange for a perpetual
royalty equal to 1.5% (2.14% including withholding tax gross up) of Net Smelter Returns (NSR) from Hycroft Mine.

Environmental,
Permitting and Social Considerations

The
Mine is located on public land administered by the Bureau of Land Management (“BLM”) and private land controlled by Hycroft
Resources and Development, LLC, a wholly owned subsidiary of Hycroft Mining Holding Company.

Hycroft
is currently authorized to operate under a plan of operations (“POO”) for ore extraction and processing, water management,
engineering, environmental studies, and exploration. In 2012, the BLM issued a Record of Decision (“ROD”) for an EIS conducted
for the Mine to expand heap leach operations, open pits, and waste rock facilities. In 2014, the BLM issued a Decision Record with an
Environmental Assessment authorizing Hycroft’s POO for construction and operations of a rail spur, open pit expansion, and construction
of a processing complex, including the TMF located northeast of the Mine.

The
TRS outlines development of additional infrastructure to support the modified Project including construction of a new TMF, waste rock
storage facilities, rail spur, and a new process plant area. Review and approval of proposed revisions to the POO by the BLM constitutes
a federal action under the National Environmental Policy Act and applicable BLM regulations. Accordingly, BLM review of the Plan Application
will require preparation of either an Environmental Assessment or an Environmental Impact Statement.
