Our Work

From Apprentice to Mentor: Powering the Future

At Resolution Copper, we’re not just building a mine. We’re investing in people and lifelong careers. Carlos’ mining journey started just a few miles from where he works today. A 2006 graduate of Superior High School, he grew up watching the legacy of mining shape his hometown. He didn’t wait long to jump in by 2007, he was underground, working on Shaft #9 with Cementation.

Mother. Daughter. Miners. A Legacy Built in Superior.

At Resolution Copper, mining isn’t just about the rock we move, it’s about the people who move it. And this Mother’s Day, we’re proud to spotlight two of those people: Jessica and Sabrina Castillo. A mother-daughter duo with deep roots in Superior, Arizona, these two powerhouse women are proving that mining, family, and community can go hand in hand - hard hats and all.

The People Behind the Project

At Resolution Copper, mining isn’t just about extracting a resource—it’s about people. It’s about hometown pride, career growth, environmental stewardship, and creating opportunities right here in the Copper Triangle.
