The U.S. Army, along with the Idaho National Laboratory and a locally headquartered mining company, has commissioned a new mineral processing plant in Idaho Falls, Idaho, that will produce a homegrown supply of antimony trisulfide, a mineral that's said to be critical to national security. The Army, along with Perpetua Resources Corp. and the Idaho National Laboratory, celebrated the opening of the pilot processing plant with a ribbon-cutting ceremony last week. The modular plant is being brought online to develop and secure a domestic supply of antimony, instead of the federal government having to source it overseas.
