September 6, 2025 - Ramaco Resources, Inc. (NASDAQ: METC, METCB, "Ramaco" or the "Company") Ramaco is pleased to announce that Hatch Ltd. ("Hatch") has been formally retained to lead the next critical analytical phase of the Brook Mine rare earth elements and critical minerals (REE/CM) project. Hatch will spearhead the development of the project's Pre-Feasibility Study (PFS), including test-work support, pilot plant design, and process flowsheet optimization.

This milestone follows a rigorous evaluation of proposals from leading engineering firms. Hatch's submission stood out for its technical depth, lean execution model, and proven expertise in hydrometallurgical unit operations—particularly in rare earth processing. Their team comprises seasoned subject matter experts and discipline engineers based in both the United States and Canada.

"Hatch brings a strong world-class process team and rare earth experience that is essential for the next development phase of this unique project," said Randall Atkins, Chairman and Chief Executive Officer for Ramaco. "This decision aligns with Ramaco's broader strategy to rapidly advance the Brook Mine project and capitalize on growing interest from government and commercial stakeholders. The PFS will serve as a foundational planning document for future permitting, investment, and offtake discussions."

"We're proud to be teaming with Ramaco on this important next phase of the Brook Mine project. Our team is excited to apply Hatch's deep expertise in rare earth processing and hydrometallurgy to help unlock the full potential of this resource," shared John Bianchini, Hatch's Chairman and CEO. "The Pre-Feasibility Study will be a critical step in shaping a technically robust and commercially viable path forward, and we're committed to delivering innovative, practical solutions that support sustainable development and long-term value."

The scope of Hatch's engagement includes:

• Developing and management of the full test-work program and coordinating with other third party national and private labs.
   
• Developing a pilot plant design package to hand over to a design/build contractor including integration with downstream purification strategies to final products.

Preparing the commercial PFS including capital and operating cost estimates to accepted industry standards, Ramaco looks forward to working closely with Hatch to deliver a comprehensive and technically sound study that supports the long-term development of the Brook Mine REE/CM project.

Ramaco acknowledges the exceptional work performed by Weir International Inc. and Fluor Corporation in advancing the Brook Mine rare earth and critical minerals initiative. Weir's updated geological assessments have reaffirmed the scale and quality of the deposit, now estimated at 1.7 million tons of total rare earth oxide (TREO) and Fluor's preliminary economic assessment (PEA) confirming the project is both commercially and technologically feasible. Both studies have validated Ramaco's development strategy and paved the way for development of the first new rare earth mine and refining project in the United States since 1952.
