Ramaco Resources, Inc.
A maker of metallurgical coal in Central Appalachia, Ramaco supplies the steelmaking ingredient to mills in North America and overseas from mines at Elk Creek, Berwind, Knox Creek, and Maben. Founded in 2015 in Lexington, Kentucky, the company also runs its Brook Mine in Wyoming, where the coal-bearing rock holds concentrations of rare earths like neodymium and dysprosium — the same elements that power the strong magnets inside electric motors and electronics.
