Sheep Creek is also unnecessary
By Guest Post,
2026-09-09Why develop a new mine at Sheep Creek when there are economically retrievable, easily accessible concentrations of Rare Earth Elements ready for the taking in Butte?. A recent study by West Virginia University (WVU) estimated that the Berkeley Pit in Butte could produce as much as 50 tons per year of rare-earth element (REE) oxides, plus roughly 18 tons per year of cobalt. In fact, REE-bearing sludge from the Berkeley Pit at Butte is already being shipped to West Virginia for concentration into usable rare earth minerals—a technology developed by WVU, based on assessments/assays by the Montana Bureau of Mines and Geology (MBMG). Further, a WV company, Mission Critical Minerals has been formed to commercialize the technology.
