South32 Hermosa

Why Hermosa?

Helping to power America’s energy future

The US has set bold goals to compete in the global critical mineral economy and secure its national security. But achieving these goals will require major investments in the nation’s infrastructure and domestic supply chain.

Located in an historic mining district in the Patagonia Mountains of Southern Arizona, South32’s Hermosa project is the only advanced mine development project in the United States to date that could produce two federally designated critical minerals—manganese and zinc—both of which are essential minerals for powering the nation’s energy future.

The 750-acres of private land where Hermosa is located also includes silver and lead. It is a part of the larger Hermosa critical minerals district, 45,000 acres of private land that includes opportunities to potentially develop copper as well as additional zinc deposits.

These mineral resources also are essential for harnessing everything from renewable energy to lithium-ion batteries and pipes and plumbing materials.

Our aspiration for the Hermosa project is to:

• Set a new standard for sustainable mining​.
• Strengthen the domestic supply chain of critical minerals​.
• Grow the local economy. ​
• Improve lives in Santa Cruz County and the surrounding community.
