Hycroft Mining Holding Corporation (Nasdaq: HYMC) is pleased to release outcomes from its S-K 1300 technical report summary and initial assessment describing project economics and a mine plan centered on conventional pressure oxidation milling combined with heap leaching at the Hycroft mine located in Nevada USA. All figures appear in US units.

The report confirms that Hycroft hosts a large long-life precious metals project offering attractive economics and meaningful leverage to higher gold and silver prices while reinforcing its status as a world-class multi-generational asset in a top-tier jurisdiction. The full technical report is being filed concurrently with the SEC on EDGAR and is available on the company website.

Technical Report Basis

Base case commodity prices set at 3600 dollars per ounce gold and 48 dollars per ounce silver
Spot price case using 4569 dollars per ounce gold and 77.94 dollars per ounce silver
Mine plan derived from the 2026 mineral resource estimate containing 16.4 million ounces gold and 562.6 million ounces silver in measured and indicated categories
Inferred resources of 5.0 million ounces gold and 132.8 million ounces silver excluded from the mine plan provide additional upside
2025-2026 exploration drilling results also excluded from the plan indicating further potential

Key Highlights

Strong economic metrics underscore project scale and value:
- Base case NPV at 5 percent equals 5.4 billion dollars pre-tax and 4.3 billion dollars after tax
- Internal rate of return reaches 18.9 percent pre-tax and 16.9 percent after tax
- Spot price NPV at 5 percent totals 10.0 billion dollars with after-tax IRR of 30.1 percent
- Payback period after tax is 4.7 years at base prices and 2.9 years at spot prices
- Gross revenue projected at 54.2 billion dollars under base case assumptions
Significant commodity price leverage:
- Each 100 dollar per ounce rise in gold price increases after-tax NPV5 by 300 million dollars
- Each 5 dollar per ounce increase in silver price lifts after-tax NPV5 by 460 million dollars
Multi-decade large-scale production profile:
- Mine life of 51 years
- Average annual output of 204000 ounces gold 6.8 million ounces silver and 295000 ounces gold equivalent
- First ten years average more than 330000 ounces gold equivalent annually
- Life-of-mine totals reach 10.4 million ounces gold 347.5 million ounces silver and 15.1 million ounces gold equivalent
Conventional plant design and processing:
- Proven pressure oxidation technology
- Existing site infrastructure supports lower capital intensity
- Plant sized for 57100 tonnes per day throughput
- Life-of-mine average cash costs of 1924 dollars per ounce gold equivalent and all-in sustaining costs of 2147 dollars per ounce gold equivalent
- Initial capital 2.4 billion dollars with life-of-mine capital totaling 3.1 billion dollars

Substantial Upside and Remaining Options

Opportunities to enhance the mine plan include further drilling to upgrade waste and inferred resources into measured and indicated categories for future inclusion conversion of high-grade Brimstone and Vortex zones to earlier production through targeted sequencing underground mining combined with open pit methods to access high-grade ounces sooner new oxide targets identified for early heap leach processing and treatment of low-grade mill feed stockpiled under the current plan but excluded from economics
The current mineral resource covers less than 15 percent of the 64000-acre land package with the Hycroft system remaining open in all directions and at depth
New exploration targets identified including high-grade and oxide opportunities with an active drilling campaign using two core rigs at Brimstone and Vortex expanding to four rigs next quarter
Pending roasting test work represents an alternative processing route that could improve project economics and generate a third revenue stream from sulfuric acid byproduct sales

Diane R. Garrett Executive Chairman and Chief Executive Officer stated that the technical study validates the size quality and long-term potential of the Hycroft mine. The project delivers robust economics and strong leverage to rising metal prices positioning Hycroft among the most compelling large-scale development opportunities in the sector within a tier-one jurisdiction. She added that the greatest value-creation opportunity lies ahead through advancement of the high-grade silver systems at Brimstone and Vortex which offer a clear path to further enhance project economics while the extensive land package continues to demonstrate significant exploration upside.

Cautionary Statement Regarding Initial Assessment and Mineral Resources

The initial assessment is a preliminary technical and economic study that outlines the economic potential of mineralization to support mineral resource disclosure at Hycroft but does not constitute a feasibility or pre-feasibility study and should not be relied upon to demonstrate economic viability or support a development decision. Hycroft intends to continue refining resource estimates and project economics. Mineral resources are not mineral reserves and have not demonstrated economic viability. Inferred resources carry high uncertainty and investors are cautioned not to assume that any portion of resources will eventually convert to reserves.
