Our Work

One Shift, One Team: A Big Win at 10 Shaft

At Resolution Copper, success isn’t just measured in tons moved or hours logged. It’s in how we show up for each other, work together, and take pride in doing things the right way.

Celebrating Indigenous Youth at NABI 2025

Resolution Copper was proud to return as Presenting Sponsor of the 2025 Native American Basketball Invitational (NABI) — and this year was the biggest one yet. With 204 Native American basketball teams representing over 160 Tribal Nations and competing in more than 500 games, NABI 2025 brought together young Indigenous athletes from across the U.S. for a week of competition, connection, and community.

Cultural Commitments: Preserving What Matters Most

At Resolution Copper, we believe cultural stewardship begins with listening. For more than a decade, we’ve built relationships with Native American Tribes and local communities whose deep ties to the land shape how we move forward. This work isn’t finished, it’s ongoing. And it’s built on respect, collaboration, and trust.

Smarter Stewardship: Setting a New Standard for Land and Water Use

At Resolution Copper, mining is only part of the story. We are equally committed to protecting the land and water that sustain our operations and our communities.

Local Support for Resolution Copper: How Mining Is Building Opportunities

Mining is deeply rooted in Arizona’s Copper Triangle—and it’s driving the region’s next chapter. Local leaders across Superior, Miami, and Kearny are voicing their strong support for the Resolution Copper project.

Powering Economic Growth in Arizona

When people talk about Arizona’s economic future, Resolution Copper is part of that conversation. This project isn’t just about mining. It’s about building opportunities. It’s about putting Arizona’s people, resources, and innovation to work in a way that delivers real, lasting impact.

Resolution Copper welcomes the republication of the Final Environmental Impact Statement (FEIS)

Resolution Copper welcomes today’s republication of the Final Environmental Impact Statement (FEIS) by the U.S. Forest Service (USFS)—a positive step forward for the project. This republication allows the USFS to advance the congressionally mandated land exchange, enabling future underground mine development and placing thousands of acres of land into permanent conservation.

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.

Statement attributable to Vicky Peacey, General Manager, Resolution Copper

We are pleased that the Ninth Circuit’s decision will stand. The Resolution Copper mine is vital to securing America’s energy future, infrastructure needs, and national defense with a domestic supply of copper and other critical minerals.
