Independent Preliminary Economic Assessment Report from Fluor Corporation Confirms Commercial and Technical Feasibility of Ramaco's Brook Mine Rare Earth Deposit

LEXINGTON, Ky., July 1, 2025 /PRNewswire/ -- Ramaco Resources, Inc. (NASDAQ: METC, METCB) ("Ramaco Resources" or the "Company") is pleased to announce that the Fluor Corporation ("Fluor") will deliver its full Preliminary Economic Assessment ("PEA") of Ramaco's Brook Mine on or before July 8, 2025. Today, Fluor has provided Ramaco with the summary results of that report which the Company is disclosing in a separate letter to Shareholders from Ramaco's Chairman and Chief Executive Randall Atkins.

The Fluor PEA states that the project is both commercially and technologically feasible. This report marks a significant step forward and builds on Fluor's earlier interim preliminary techno-economic analysis. The Brook Mine holds what is believed to be the nation's largest unconventional deposit of rare earth elements and critical minerals sourced from coal and carbonaceous ore.

Key Highlights:

• Shareholder Letter: In conjunction with today's press release, the Company is releasing a shareholder letter from Randall Atkins, Ramaco's Chairman and Chief Executive describing the economics and the Company's vision for the Brook Mine rare earth element and critical mineral project. The shareholder letter can be found on the Company's website.
  
  
• NPV & IRR: The results of the Brook Mine PEA outline NPV8 (net present value using an 8% discount rate) of $1.197 billion and NPV10 (net present value using a 10% discount rate) of $898 million (pre-tax) and an IRR (internal rate of return) of 38% with a total initial capital cost estimate of $473 million (excluding a 22% capital expenditure contingency).
  
  
• Annual Economics and Production: The results of the Brook Mine PEA outline that based upon the current mine plan of a 2 million ton per annum production of coal that the adjusted EBITDA (see footnote for definition) from the rare earth and critical mineral operation would be $134 million by 2028. Steady state adjusted EBITDA of $143 million would be reached by 2029 on $378 million of annual revenue. At steady state, 1,242 annual short tons of oxide are projected to be produced, which include 456 tons of gallium, germanium, scandium, terbium, dysprosium, neodymium, and praseodymium. Given the size of the Brook Mine deposit, this level of both mining and processed oxide production is scalable.
  
  
• Full PEA: The full Preliminary Economic Assessment from Fluor will be available on or before July 8^th on the Company's website. The Company's recently updated Exploration Target from Weir International Inc. remains unchanged and is on the Company's website. As a reminder, it shows a total rare earth oxide of up to 1.7 million tons from the currently permitted 4,500-acre area of the Brook Mine. An additional approximately 11,500 acres remain for future exploration and development.

We believe that the updated Preliminary Economic Assessment conducted by Fluor offers compelling new confirmation of the Brook Mine project's viability. This independent evaluation not only validates Ramaco's current development strategy but also provides strong momentum to advance the project's next phases.

Unlike traditional rare earth element (REE) deposits, which often involve complex, high-cost processing and the management of radioactive elements contained in the ore, the Brook Mine deposit is composed of soft, friable, clay and rock associated with coal and negligible radioactive elements. This unique geological profile significantly reduces the cost and requirement for energy-intensive processing typically required in hard rock mining.

As a result, the project is expected to benefit from a more efficient separation and extraction process with lower capital intensity than with hard rock deposits. Additionally, the simplified mineralogy supports a streamlined flow sheet, which could reduce operational complexity and lead to lower overall capital and operating costs.

Specifically, a flowsheet for the Brook Mine project comprises a conventional comminution circuit, a multi-stage liberation process, followed by purification, separation, and calcination to produce separated critical mineral oxides. Aspects of this flowsheet contain proprietary intellectual property.

In terms of the details, the capital cost estimate was completed by Fluor to an AACE Class 5 estimate including a 22% contingency and escalation. This is shown below.

Specifically, a successful bench-scale test work program managed by Fluor, supports flowsheet development and confirms exceptional light and heavy rare earth element leach extractions averaging 90%, and overall leach extractions including critical minerals achieving mid-80's %.

On the production front, the chart below shows projected annual production levels.

The project cost estimates are shown below.

On the revenue front, long term rare earth and critical mineral pricing forecasts for domestic sourced materials were obtained from industry sources. The chart below shows the prices for our most valuable products together with their projected revenue and production metrics.

The chart below shows that Adjusted EBITDA of $143 million is anticipated by 2029 at steady state production on the back of $378 million of annual revenue.

An initial mine life of 42 years is assumed in the PEA. However, the initial mine life consumes less than 4% of the estimated total mineral inventory at the Brook Mine deposit. This highlights the large-scale long-term potential of this mine to be a major domestic producer of rare earths and critical minerals.

Initial mining activities have commenced at the Brook Mine to procure representative ore for the upcoming pilot scale metallurgical testing. These efforts will support the construction and commissioning of an onsite pilot plant, targeted to begin in the fourth quarter of 2025. The on-site pilot plant will support commercial design and product development and is anticipated to be fully operational by mid-2026 to ship product to potential customers for testing.

"This report marks an important milestone in Ramaco's transition to become both a rare earth and critical mineral, as well as metallurgical coal producer. The development of our Brook Mine deposit is important not only to Ramaco but also to our country," said Randall Atkins, Chairman and CEO of Ramaco Resources. "Importantly, this analysis from Fluor, an internationally recognized independent engineering firm, validates our continued pursuit of the development of this potentially valuable and nationally strategic deposit.

"When we are in production, the Brook Mine will be one of only two domestic sources of rare earth elements. However, it will be the only domestic source of both heavy rare earth elements and critical minerals that are vital to our nation's defense industry. Based on just the magnet rare earth oxides projected to be produced at current levels, we believe the Brook Mine would support 3-5% of total United States permanent magnet demand or more than 30% of the demand for U.S. defense applications estimated at 10% of total U.S. magnet metal demand.

"Today is an exciting day for Ramaco's transition, but also for a new supply line for the country's critical need for rare earth elements. China may now be dominating these critical materials. But this will be America's rare earth mine.

"We will continue to keep our shareholders apprised of important developments along our path to full-scale commercialization. I would encourage you to read my shareholder letter that outlines our vision for the Brook Mine."
