ABOUT Hermosa

Hermosa, located approximately 75 miles south-east of Tucson, Arizona, is the only advanced mining project in the United States as of 2023 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.

ACERCA de Hermosa

Hermosa, ubicado a aproximadamente 75 millas al sur este de Tucson, Arizona, es el único proyecto de minería avanzada en los Estados Unidos hasta la fecha que puede producir dos minerales designados como críticos por el gobierno federal: manganeso y zinc, así como también plata y plomo. El proyecto tiene el potencial de ayudar a impulsar el futuro energético limpio del país, reforzar la cadena de suministro nacional de minerales esenciales, hacer crecer la economía local y mejorar la calidad de vida en el condado de Santa Cruz y en las comunidades aledañas para las generaciones venideras.
