Ramaco Resources METC Ree Critical Minerals — Revenue

The Rare Earths and Critical Minerals segment encompasses the Brook Mine complex located in Sheridan, Wyoming, where the Company is evaluating a rare earth and other critical mineral project in addition to performing initiatives related to coal-to-carbon based products and materials. The Brook Mine, which is an exploration stage property, has provided representative mineralized material for short-term pilot-scale testing of the feedstock with the goal of supporting more advanced mining studies ultimately establishing rare earth element and other critical mineral reserves for processing into rare earth element and other critical mineral products. There is no assurance that we will be able to successfully develop the Brook Mine into a commercial scale mine, and there is no certainty that any part of the inferred mineral resources estimated will be converted into higher confidence mineral resources and eventually mineral reserves in the future. No revenues have been recognized from the Rare Earths and Critical Minerals segment.
