Arizona Federal Court Denies Request to Halt Hermosa Critical Minerals Project

The U.S. District Court for the District of Arizona last week denied a motion for a preliminary injunction to halt construction of the Hermosa Critical Minerals Project in southeastern Arizona. The project will establish a domestic source of manganese and substantially increase domestic production of zinc, which are essential to the steel used in military vehicles and naval vessels. In battery-grade form, manganese is also essential to the advanced lithium-ion batteries that power unmanned aerial vehicles, radios, and other defense equipment. The United States relies entirely on imports of manganese and almost entirely on imports of zinc, with China providing about 95% of global refining capacity for manganese used in advanced batteries.
