Hermosa Critical Minerals Mining Project

under construction

The Hermosa Critical Minerals Project in Southern Arizona's Patagonia Mountains is a mining project that could produce up to five federally designated critical minerals including zinc, silver, and manganese. The project includes a broader land package with potential for additional polymetallic and copper mineralization. It involves building ancillary infrastructure such as a primary access road, a secondary dry-stack tailings facility, and a 138-kV power line on Coronado National Forest land. Construction is already halfway complete on private land.
