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.
In Arizona, mining isn’t just part of the past. It’s the backbone of the present and the promise of the future. For more than 100 years, copper has helped shape this state. Since 1910, Arizona has led the nation in copper production. From the red rock cliffs of the Copper Triangle to the machinery that hums deep underground, the industry has powered homes, built cities, and sparked innovation across generations.
This Economic Development Week, we’re celebrating the partnerships, investments, and milestones that are helping the Copper Triangle thrive. Since 2019, we’ve invested more than $8.9 million into projects that drive long-term growth — from workforce programs and school upgrades to trail revitalization, tourism boosts, and business development.
At Resolution Copper, we’ve reached a major milestone: over $2 billion invested in developing and permitting one of the most important copper projects in the United States. This number tells a bigger story — one of progress, partnerships, and purpose.
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.
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.
