Current Status

Current Status of Federal Permitting

The Resolution Copper project has reached a major federal milestone.
On March 16, 2026, the congressionally mandated land exchange was recorded, and the U.S. government issued the final Record of Decision (RoD). This action completes the federal land exchange process and authorizes future special use permits for pipelines, powerlines, and roads across National Forest System lands.

What this means

  • The land exchange directed by Congress in 2014 is now complete.
  • Federal environmental review under the National Environmental Policy Act (NEPA) is finished.
  • The U.S. Forest Service (USFS), as the lead federal agency, has concluded its review and issued its final decision.
  • The project now moves from federal land exchange review into enabling work, additional studies, and state-level permitting.

What Comes Next

With the land exchange completed, the project moves into its next phase.

The next steps planned include:

  • Approximately $500 million in committed investment for enabling work for the next two years.
  • Surface drilling to collect additional resource information.
  • Upgrades to existing site infrastructure to prepare for potential underground development.
  • Continued collaboration with local communities and Native American Tribes.
  • Ongoing state-level permitting in advance of a future investment decision.

No decision has been made to begin mining. Future phases will be subject to additional review, permits, and community engagement.

Resolution Copper recognizes the significance of this project to local communities, Tribal Nations, and Arizona. We remain committed to transparency, regulatory compliance, and ongoing dialogue as the project progresses.

For official federal documents and updates, the U.S. Forest Service maintains the authoritative public record.

Our Work

Teamwork Powers 46 Level Upgrade

Deep underground at Resolution Copper, crews recently completed a major upgrade to the 46 Level pump station, modernizing a critical system that helps manage water in the mine's underground workings.

A Decade of Showing Up

Since 2016, Resolution Copper has invested more than $20 million through more than 900 partnerships supporting rural Arizona communities.Those partnerships span education, health and wellbeing, culture and heritage, environmental stewardship, business development, recreation and community economic development.

More Than a Game: How Baseball Became a Classroom

Since 2012, Resolution Copper and the Arizona Diamondbacks have worked together to create opportunities for Arizona youth, educators and communities.

Stewardship Starts Here | Stephen’s Story

Stephen learned early in life that taking care of the environment matters. His father spent his career working in renewable energy and taught him the importance of respecting the earth and preserving it for future generations. Those lessons stuck.

From Trails to Roadsides: Stewardship in Action

There are plenty of things you might expect to see during a day at Resolution Copper. Engineers solving problems. Teams working underground. People in meetings. Hard hats, high-vis and plenty of equipment.

A Superior native reflects on leaving home, coming back and building a career close to the place that shaped him. Growing up in Superior, Arizona, Mike spent his afternoons coming home from school, jumping on his dirt bike and heading straight into the desert.

The Descent: What It’s Like Traveling Nearly 7,000 Ft. Underground

From the surface, 7,000 ft. is hard to picture. It is just a number until you walk toward the shaft, pass beneath the headframe and reach the collar, where the scale starts to come into focus. The opening drops below, surrounded by steel, hoisting equipment and the systems that move people safely between the surface and the underground workings.

Testing What Matters Most: How One Team Helped Make Underground Refuge Chambers Even Safer

When people think about mine safety, they often picture hard hats, reflective clothing and safety inspections. Those are all important, but some of the most important safety work happens long before an emergency occurs, through planning, testing and preparation.

8 Billion Gallons Recycled: Our Commitment to Responsible Water Management

Since 2009, Resolution Copper has treated and provided more than 8 billion gallons of water for agricultural use in Arizona. It is a major milestone for a program that starts nearly 7,000 feet underground and ends in local farm fields.
