The hidden gemRamaco Resources, Inc. Class ABATS:METCAllAboutMoneyI’ve been following this company for several months, and I believe it could be the next mining stock to take off. We saw it happen with SSRM and HYMC, both delivering gains of more than 300%. Why is METC an interesting opportunity? The company produces metallurgical coal, which is used to manufacture steel for construction, automobiles, and other industries. But what makes the story even more interesting is its exposure to rare earth minerals. This sector could experience explosive growth in the United States, as the rising production of chips, electric motors, and other advanced technologies makes it increasingly important for the U.S. to have domestic companies like this one.
