Negatives

• All reported mineral resources (CMO and coal) are classified as Inferred, representing the lowest level of geological confidence, and are not yet Mineral Reserves.
• Deep core drilling results did not reveal any substantial high-grade ore zones at depths below the Lower 7 Seam; critical mineral levels were generally lower there.
• Recruiting suitable personnel to operate the mine and processing facility may be a challenge due to the rural location near Sheridan, Wyoming (population ~20,000).
• Market conditions for Critical Mineral Oxides (CMOs) are likely to be volatile, and no material supply contracts have been established yet for either CMOs or thermal coal.
• Tailings ponds are anticipated for CMO processing, with designs currently in progress, indicating potential environmental management complexities.
• Bulk sampling through under-reaming proved ineffective for coal seam samples due to excessive dilution, and samples were not representative.

Risks

• Implied spatial continuity extents of Inferred Resources, which are by definition too uncertain to assume continuity or mineability with confidence.
• Ongoing need for seam and lithology correlation and structural definition.
• Identification and mapping of faulting throughout the deposit.
• Areas of low ICP-MS sampling coverage, particularly below the Masters Seam, leading to higher geological uncertainty.
• Geotechnical evaluations of surface mining feasibility and mineral recovery at significant depths are required.
• Volatility of CMO and mineral sales prices, as no material supply contracts are currently in place.
• Significant variations in operating cost, processing recoveries, capital expenditures, and productivity could preclude economic mineability.
• Unforeseen changes in legislation and new industry developments could positively or negatively alter performance by impacting demand, regulations, permitting, and taxes.
• Challenges in acquiring suitable personnel to operate the mine and processing facility.
• Refuse disposal requirements for CMO processing are still under study.
• Potential for spontaneous combustion in coal seams, though mitigable through stockpile management.
• The timeline to production and expanded production is subject to obtaining all required federal, state, and local permits and licenses without unforeseen or undue delays.

Future Outlook

Ramaco Resources plans to significantly expand its Brook Mine permit to cover its entire 16,000 acres of control, aiming to increase base coal production to 5 million tons per year and critical mineral oxide production to 3,400 tons per year, extending the mine life to over 60 years. The company expects its pilot plant to begin operation later this year, with commercial oxide plant construction potentially starting in late 2026. A Pre-Feasibility Study is anticipated in Q1 2026, and a fall drilling program is underway to further define and expand the resource. The company also anticipates finalizing an expanded revolving credit facility in Q4 2025, providing additional funding for project development.

Management Comments

• "Since our groundbreaking of the Brook Mine in July we have rapidly moved to build on the momentum of being the first new rare earth mine in the United States in 70 years."
• "We have now begun the transition into the nations first dual platform critical minerals company."
• "It has been called the largest unconventional rare earth deposit in North America by the Department of Energy's National Energy Technology Laboratory."
• "We hope that an acceleration to this schedule will enable the Company to have a first mover advantage in terms of initiating new United States production, but also as the dominant domestic producer in providing the country with our specific REEs and CMs for decades to come."
• "The more than doubling of the production will enable the Company to better serve key domestic industries in defense, semiconductors, energy, electronics and aerospace while reducing their reliance on foreign sources of REE and CM."
• "We have known Joe for many years and regard him as one of the most talented young financial figures in the energy space."

• "I have worked closely with and known Joe for years and we are looking forward to what he can bring to our financial bench at Ramaco."

Industry Context

The announcement comes amidst a broader industry trend emphasizing domestic critical mineral production, driven by national security and economic resilience concerns. The market for Rare Earth Elements (REEs) and Critical Minerals (CMs) is increasingly bifurcated, with unstable supply lines from China contrasting with a growing demand for reliable Western sources. Ramaco's Brook Mine project is positioned to become a dominant domestic producer, addressing this supply gap. The company highlights significant Western price premiums for certain REEs like Terbium and Gadolinium compared to Chinese prices, reflecting the market's valuation of secure supply. The growing demand for Scandium oxide, particularly from the aerospace industry, further underscores the strategic importance of new domestic sources.

Comparison to Industry Standards

• Brook Mine's Critical Mineral Oxide (CMO) concentrations are estimated to rank "among the highest concentrations of REEs found in any deposits on a world-wide basis, including Chinese deposits," according to analysis by the U.S. Department of Energy's National Energy Technology Laboratory (NETL).
• The coal quality at Brook Mine (high BTU, low sulfur, low ash thermal coal) is typical of Powder River Basin (PRB) coal, a well-established coal-producing region in the United States.
• The global market for Scandium currently lacks large-scale reliable Western supply, with most scandium oxide originating from China. Ramaco believes a reliable Western index for scandium would show similar premiums to Chinese pricing as observed for other REEs.
• Western REE indices show Terbium trading close to $4 million per tonne as of mid-September 2025, significantly higher than Chinese price indices of over $1 million per tonne.
• Western indices for Gadolinium are approximately 5.5 times higher than those in China, illustrating the bifurcated pricing market.
