HYCROFT MINING HOLDING CORP

About the Company

Hycroft Mining Holding Corporation (formerly known as Mudrick Capital Acquisition Corporation) was incorporated under the laws of the state of Delaware on August 28, 2017. In this 2024 Form 10-K, “we,” “us,” “our,” “Company,” “Hycroft,” and “HYMC” refer to Hycroft Mining Holding Corporation and its subsidiaries. We are a U.S.-based gold and silver exploration and development company that owns the Hycroft Mine in the prolific mining region of Northern Nevada. The following discussion should be read in conjunction with the Company’s Consolidated Financial Statements (“Financial Statements”) and Notes to the Financial Statements included in Part II– Item 8. Financial Statements and Supplementary Data of this 2024 Form 10-K.

On May 29, 2020, we consummated a business combination transaction (the “Recapitalization Transaction”) that resulted in our wholly owned subsidiary Autar Gold Corporation (formerly known as MUDS Acquisition Sub, Inc. (“Acquisition Sub”)) acquiring all of the issued and outstanding equity interests of the direct subsidiaries of Hycroft Mining Corporation (“HMC”) and substantially all of the other assets of HMC and assuming substantially all of HMC’s liabilities. In conjunction with the Recapitalization Transaction, HMC’s indebtedness existing prior to the Recapitalization Transaction was either repaid, exchanged for indebtedness of the Company, exchanged for shares of common stock or converted into shares of HMC common stock, and our post-Recapitalization Transaction indebtedness included amounts drawn under the Sprott Credit Agreement (as defined below) among Hycroft, AuxAg Mining Corporation (formerly known as MUDS Holdco Inc.), Allied VGH LLC, Hycroft Resources and Development, LLC, Sprott Private Resource Lending II (Collector) Inc., and Sprott Resources Lending Corp. (“Sprott Credit Agreement”) and the assumption of the newly issued 10% Senior Secured Notes (“Subordinated Notes”).

Our property, the Hycroft Mine, historically operated as an open-pit oxide mining and heap leach processing operation. It is located approximately 54 miles northwest of Winnemucca, Nevada. Mining operations at the Hycroft Mine were restarted in 2019 on a pre-commercial scale and discontinued in November 2021 as a result of the then-current and expected ongoing cost pressures for many of the reagents and consumables used at the Hycroft Mine and to further determine the most effective processing method for the sulfide ore. Processing of gold and silver ore previously placed on leach pads was completed as of December 31, 2022. In March 2023, Hycroft, along with its third-party consultants, completed and filed the Hycroft Property Initial Assessment Technical Report Summary Humboldt and Pershing Counties, Nevada with an effective date of March 27, 2023 (the “2023 Hycroft TRS”) and prepared in accordance with the SEC’s Modernization of Property Disclosures for Mining Registrants as set forth in subpart 1300 of Regulation S-K (“Modernization Rules”). The 2023 Hycroft TRS provides an initial assessment of the mineral resource estimate utilizing a milling and pressure oxidation (“POX”) process for sulfide and transition mineralization and a heap leaching process for oxide mineralization and some transition mineralization. The 2023 Hycroft TRS included: (i) additional exploration drilling results from 2021 and 2022; (ii) additional assay information associated with historical drilling that was previously missing; (iii) other updates after additional review of historical assay certificates; and (iv) other adjustments. The 2023 Hycroft TRS superseded and replaced the Initial Assessment Technical Report Summary for the Hycroft Mine, prepared in accordance with the requirements of the Modernization Rules, with an effective date of February 18, 2022 (“2022 Hycroft TRS”), and the 2022 Hycroft TRS should no longer be relied upon. Our ongoing disclosures and many of management’s estimates and judgments as of and for the periods ended December 31, 2024 and 2023, are based on the 2023 Hycroft TRS. The Company will continue to build on the work to date, incorporate exploration data as it becomes available, and investigate opportunities identified through progressing the technical and data analyses leading up to the 2023 Hycroft TRS and subsequent studies and analyses, and we will provide an updated technical report currently targeted for the fourth quarter of 2025.

We do not expect to generate revenues from gold and silver sales until after further developing the Hycroft Mine and recommencing mining and processing operations. To achieve this, we will require additional funding. As of December 31, 2024, the Hycroft Mine had measured and indicated mineral resources of 10.6 million ounces of gold and 360.7 million ounces of silver and inferred mineral resources of 3.4 million ounces of gold and 96.1 million ounces of silver, which are contained in oxide, transitional, and sulfide ores.

Segment Information

The Hycroft Mine is our only operating segment and includes the mine site, exploration, and development activities. Direct support costs account for 100% of the segment’s Operating expenses. Corporate and Other includes corporate General and administrative costs. See Note 20 – Segment Informationto the Notes to the Consolidated Financial Statements for additional information on our segments.

Principal Products, Revenues, and Market Overview

During the years ended December 31, 2024 and 2023, the Company generated no revenues due to the cessation of active mining operations in November 2021.

Product Revenues and Customers

As the Company ceased active mining operations in November 2021 and completed the processing of gold and silver ounces from the leach pads by the end of 2022, we do not expect revenues from gold and silver sales until restarting mining operations.

Gold and Silver Uses

Gold and silver have two main categories of use: fabrication and investment. Fabricated gold has a variety of end uses, including jewelry, electronics, dentistry, industrial and decorative applications, medals, medallions, and coins. Fabricated silver also has a variety of end uses, including jewelry, mirrors, cameras, electronics, energy production, engines, novelty explosives, and coins. Gold and silver investors buy gold and silver bullion, coins, and jewelry.

Gold and Silver Supply and Demand

The supply of gold consists of a combination of current production from mining and metal recycling and the draw-down of existing stocks of gold held by governments, financial institutions, industrial organizations, and private individuals. Based on publicly available information published by the World Gold Council, gold from mine production increased 0.5% in 2024 compared with 2023 totaling approximately 3,661 metric tons (or 117.7 million troy ounces) and represented approximately 73.6% of the 2024 global gold supply of 4,975 metric tons. According to the World Gold Council, gold demand in 2024 was approximately 4,554 metric tons (or 146.4 million troy ounces) and totaled approximately $382 billion in value. In 2024, gold demand by sector was comprised of jewelry (40%), investments including bar and coin and ETFs (24%), central bank purchases (21%), and technology (7%).

The supply of silver consists of a combination of current production from mining (approximately 82%) and metal recycling and other (approximately 18%). Based on publicly available information, estimated silver from mine production decreased approximately 1% in 2024 compared with 2023, totaling approximately 824 million troy ounces, and represented approximately 82% of the 2024 global silver supply of 1,004 million troy ounces. Silver demand in 2024 was approximately 1,219 million troy ounces and totaled approximately $34.5 billion in value. In 2024, silver demand by sector was comprised of electrical and electronics (40%), investments (17%), jewelry (17%), other industrial (14%), silverware (5%), and photography (2%).

Gold and Silver Prices

The price of gold and silver is volatile and is affected by many factors beyond our control, including geopolitical events, such as conflicts or trade tensions, the sale or purchase of gold by central banks and financial institutions, inflation or deflation and monetary policies, fluctuation in the value of the U.S. dollar and foreign currencies, global and regional demand, and the political and economic conditions of major gold and silver producing countries throughout the world. The following table presents the annual high, low, and average afternoon fix prices for gold and silver since January 1, 2022 on the London Bullion Market (in U.S. dollars per ounce).

On March 4, 2025, the afternoon fix price for gold and silver on the London Bullion Market was $2,881 per ounce and $31.53 per ounce, respectively.

Competition

The top ten producers of gold comprise approximately one-quarter of total worldwide mined gold production. We are a gold and silver exploration and development company with a single property, the Hycroft Mine. The Hycroft Mine has a large gold and silver mineral resource as noted in the 2023 Hycroft TRS. We have not completed our engineering studies, and we have not fully developed our sulfide ore milling and processing studies and, therefore, have not established our long-term production and cost structure. The metals markets are cyclical, and our ability to compete in that market over the long term will be based on our ability to develop and cost-effectively operate the Hycroft Mine in a safe and environmentally responsible manner.

We compete with other mining companies to hire and retain qualified employees. There is substantial competition for qualified employees in the mining industry, some of which are with larger companies having greater financial resources than us and a more stable history. As a result, we may have difficulty hiring and retaining qualified employees.

See Item 1A. Risk Factors — Industry-Related Risks — The Company faces intense competition in the recruitment and retention of qualified employees and contractors, for additional discussion related to our current and potential competition.

Human Capital

At December 31, 2024, we had 56 employees, of which 48 were employed at the Hycroft Mine. None of our employees are represented by unions.

We believe safety is a core value and support that belief through our philosophy of safe work performance. Our mandatory mine safety and health programs include employee engagement and ownership of safety performance, accountability, employee and contractor training, risk management, workplace inspection, emergency response, accident investigation, anti-harassment, and program auditing. This integrated approach is essential to ensure that our employees, contractors, and visitors operate safely.

We reported no lost time incidents during the year ended December 31, 2024, and achieved one million work hours without a lost time incident in the second quarter of 2024. The Hycroft Mine’s total recordable injury frequency rate (“TRIFR”) for the trailing 12 months, which includes other reportable incidents, is one of the metrics we use to assess safety performance, and it is well below industry averages and significantly below pre-2021 historical levels experienced at the Hycroft Mine. During the year ended December 31, 2024, the Company continued its critical focus on safety, including allocating additional personnel, resources, workforce time, and communications to operate safely. These actions contributed to maintaining our TRIFR of 0.00 at both December 31, 2024 and December 31, 2023. The Company remains committed to adapting safety initiatives as necessary to ensure the well-being of our workforce, contractors, and visitors.

Government Regulation of Mining-Related Activities

Government Regulation

Mining operations and exploration activities are subject to various federal, state and local laws and regulations in the United States, which govern prospecting, exploration, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, mine safety, hazardous substances and other matters. We have obtained or have pending applications or pending application renewals for those licenses, permits, or other authorizations currently required to conduct our current operations, exploration and other programs. We believe we are in compliance in all material respects with applicable mining, health, safety and environmental statutes and the regulations passed thereunder in Nevada and at the federal level in the United States. Although we are not aware of any current claims, orders or directions relating to our business with respect to the foregoing laws and regulations, changes to, or more stringent application, interpretation, or enforcement of, such laws and regulations in Nevada, or in jurisdictions where we may operate in the future, could require additional capital expenditures and increased operating and/or reclamation costs, which could adversely impact the profitability levels of our projects.

Environmental Regulation

Our projects are subject to various federal and state laws and regulations governing protection of the environment. These laws and regulations are continually changing and, in general, are becoming more restrictive. The federal laws and regulations, among other things:

•impose strict, joint and several liability on current and former owners and operators of sites and on persons who disposed of or arranged for the disposal of hazardous substances found at such sites (the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”));

•govern the generation, treatment, storage and disposal of solid waste and hazardous waste (the Resource Conservation and Recovery Act of 1976, as amended (“RCRA”));

•restrict the emission of air pollutants from many sources, including mining and processing activities (the Clean Air Act of 1970, as amended (the “Clean Air Act”));

•require federal agencies to integrate environmental considerations into their decision-making processes by evaluating the environmental impacts of their proposed actions, including the issuance of permits to mining facilities and assessing alternatives to these actions (the National Environmental Policy Act of 1970, as amended (“NEPA”));

•regulate the use of federal public lands to prevent undue and unnecessary degradation of the public lands (the Federal Land Policy and Management Act of 1976, as amended (the “FLPMA”));

•restrict and control the discharge of pollutants and dredged and fill materials into waters of the United States (the Clean Water Act of 1972, as amended (the “Clean Water Act”)); and

•regulate the drilling of subsurface injection wells (the Safe Drinking Water Act of 1974, as amended (the “Safe Drinking Water Act”) and the Underground Injection Control Program promulgated thereunder).

We cannot predict at this time what changes, if any, to federal laws or regulations may be adopted or imposed by the current federal governmental administration. At the state level, mining operations in Nevada are regulated by the Nevada Department of Conservation and Natural Resources, Division of Environmental Protection, which has the authority to implement and enforce many of the federal regulatory programs described above, as well as state environmental laws and regulations. Compliance with these, and other federal and state laws and regulations, could result in delays in obtaining, or failure to obtain, government permits and approvals, delays in beginning or expanding operations, limitations on production levels, incurring additional costs for investigation or cleanup of hazardous substances, payment of fines, penalties or remediation costs for non-compliance, and post-mining closure, reclamation and bonding.

It is our policy to conduct business in a way that safeguards our employees, public health and the environment. Our operations are, and are planned to be, conducted in material compliance with applicable laws and regulations. However, our past and future activities may cause us to be subject to liability under such laws and regulations. For information about the risks to our business related to environmental regulation, see the following risk factors in Item 1A. Risk Factors – Industry-Related Risks:

•The Company relies upon numerous governmental permits that are difficult to obtain, and the Company may not be able to obtain or renew all of the required permits, or such permits may not be timely obtained or renewed;

•Environmental regulations could require the Company to make significant expenditures or expose the Company to potential liability;

•Failure to comply with environmental regulations could result in penalties and costs; and

•Compliance with current and future government regulations may cause the Company to incur significant costs.

During the year ended December 31, 2024, the Company received correspondence from regulatory agencies regarding various environmental and reclamation matters, including permit renewals and site compliance, with no material impact on operations. During 2024 and 2023, there were no known material environmental incidents. We did not incur material expenditures for environmental control facilities during 2024 and 2023, and we do not expect to incur any material expenditures for environmental control facilities in 2025.

Reclamation

We are required to mitigate long-term environmental impacts by amending, backfilling, stabilizing, contouring, re-sloping, and re-vegetating various portions of a site after mining and mineral processing are completed, mitigating potential impacts to surface water and groundwater resources. These reclamation efforts will be conducted in accordance with detailed plans, which must be reviewed and approved by the appropriate regulatory agencies. Our reclamation obligations at the Hycroft Mine are secured by surface management surety bonds that meet the financial assurance requirements of the State of Nevada, U.S. Department of the Interior, and the Bureau of Land Management (“BLM”). Our most recent reclamation cost estimate was approved by the BLM and the State of Nevada in July 2020. As of December 31, 2024, our surface management surety bonds totaled $58.7 million, of which $58.3 million secures the financial assurance requirements for the Hycroft Mine, and $0.4 million secures the financial assurance requirements for the adjacent water supply well field and exploration within the project boundary. The Company began performing reclamation activities on its Crofoot leach pad beginning in 2023 and continued Crofoot reclamation activities in 2024. We currently plan to conduct additional reclamation activities on the Crofoot leach pad in 2027, and we also expect to treat and manage solutions in certain ponds continuing through 2026. No additional material reclamation expenditures are expected to be incurred until after mining and mineral processing are substantially completed. If we incur additional long-term environmental impacts from future mining activities, we will likely have additional reclamation obligations, as well as additional financial assurance requirements. For our existing obligations, as well as any future obligations we may incur, we may choose to engage in reclamation activities before mining and mineral processing are completed, but these expenses are not anticipated to be material to the overall reclamation obligation. When we perform reclamation work in the future, the work will be planned to conform to our mining operations and will be required to be documented when completed under our governing permits. The reclamation obligation would be adjusted accordingly as allowed under current regulations, and the financial assurance requirements would be adjusted to account for the completed reclamation work. If we are required to comply with material unanticipated financial assurance requirements in the future, our financial position could be adversely affected, or our posted financial assurance may be insufficient. For financial information about our estimated future reclamation costs, see Note 10 – Asset Retirement Obligation to the Notes to the Consolidated Financial Statements.

Mine Safety and Health Administration Regulations

Safety and health are core values, which is why we have mandatory mine safety and health programs that include employee and contractor training, risk management, workplace inspection, emergency response, accident investigation, and program auditing. We consider these programs to be essential at all levels within Hycroft to ensure that our employees, contractors, and visitors operate in a safe and healthy workplace.

Our operations and exploration properties are subject to regulation by the Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977, as amended (the “Mine Act”). Pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as amended (the “Dodd-Frank Act”), issuers are required to disclose specified health and safety violations, orders and citations, related assessments and legal actions, and mining-related fatalities in periodic reports. MSHA inspects our mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. The number of citations and orders charged against mining operations in the U.S., and the dollar penalties assessed for such citations, have generally increased in recent years. The Dodd-Frank Act requires us to provide certain mine safety disclosure that are provided in Part I – Item 4. Mine Safety Disclosures of this 2024 Form 10-K.

Property Interests and Mining Claims

Our exploration and development activities are conducted at the Hycroft Mine in the State of Nevada. Mineral interests in Nevada may be owned by the United States, the State of Nevada, or private parties. Where prospective mineral properties are held by the United States, mineral rights may be acquired through the location of unpatented mineral claims upon unappropriated federal land. Where prospective mineral properties are owned by the State of Nevada or private parties, some type of property acquisition agreement or access agreement is necessary for us to explore or develop such property. Mining claims are subject to the same risk of defective title that is common to all real property interests. Additionally, mining claims are self-initiated and self-maintained and, therefore, possess some unique vulnerabilities not associated with other types of property interests. It is impossible to ascertain the validity of unpatented mining claims solely from an examination of the public real estate records, and, therefore, it can be difficult or impossible to confirm that all of the requisite steps have been followed for location and maintenance of a claim. For general information about our mineral properties and mining claims, see Item 2. Properties. For information about the risks to our business related to our property interests and mining claims, see the following risk factors in Item 1A. Risk Factors– Industry-Related Risks:

•There are uncertainties as to title matters in the mining industry. Any defects in such title could cause the Company to lose its rights in mineral properties and jeopardize our business operations; and

•Legislation has been proposed periodically that could, if enacted, significantly affect the cost of mine development on the Company’s unpatented mining claims.

Technical Report Summaries (“TRS”) and Qualified Persons

The scientific and technical information concerning our mineral projects in the 2024 Form 10-K have been reviewed and approved by third-party “qualified persons” under the Modernization Rules, including Ausenco Engineering South USA, Inc. (“Ausenco”), Independent Mining Consultants, Inc, (“IMC”), and WestLand Engineering & Environmental Services, Inc. (“WestLand”). For a description of the key assumptions, parameters and methods used to estimate mineral resources included in the 2024 Form 10-K, as well as data verification procedures and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, sociopolitical, marketing or other relevant factors, please review the 2023 Hycroft TRS incorporated by reference herein.
