According to the source statement: The U.S. District Court for the District of Arizona denied a preliminary injunction motion to stop construction of the Hermosa Critical Minerals Project. This project aims to create a domestic source of manganese and significantly increase zinc production, both essential for steel in military vehicles and naval ships. Manganese is also critical in battery-grade form for advanced lithium-ion batteries used in unmanned aerial vehicles, radios, and other defense equipment. The U.S. is almost entirely reliant on imports for manganese and zinc, with China supplying about 95% of global refining capacity for manganese used in advanced batteries.
