Alliance Resource Partners LP
A coal producer and natural resource company from Tulsa, Oklahoma, Alliance Resource Partners runs several underground mines across the Illinois Basin and holds oil-and-gas royalty acres in the Permian, Anadarko, and Williston basins. Its roots date to 1971, when MAPCO Inc. began buying coal mines; management bought them out in 1996 and went public in 1999 as the first master limited partnership in coal. It also mines bitcoin via its Bitiki subsidiary, using surplus power at a Kentucky coal mine.
