Specialist, Process Control - Metallurgy

About the Project

Hermosa, located approximately 75 miles south‑east of Tucson, Arizona, is the only advanced mining project in the United States that could produce two federally designated critical minerals—manganese and zinc—as well as silver and lead. The project has the potential to help power the nation’s clean‑energy future, strengthen the domestic supply chain of critical minerals, grow the local economy, and improve lives in Santa Cruz County and the surrounding community for generations to come.
