Our Work

From Geology Roots to Modern Mining: Ginger’s Journey

For Ginger, mining isn’t just a career. It is a way to honor her father’s passion for geology and the Arizona landscape he loved. More than 30 years ago, her dad, a hydrogeologist, moved the family to Arizona drawn to the region’s geology, water systems, and the potential beneath the surface. He passed away 20 years ago, but his curiosity stayed with her. “Working at the Resolution Copper project would have been a dream job for him,” she says. “Every time I go underground, I think of him. It feels like I’m walking the path he never got to take.”

Building Stronger Communities Together: December 2025

At Resolution Copper, our mission is to responsibly develop one of the world’s largest copper resources while creating lasting benefits for the communities around us. That means investing in education, supporting local economies, and partnering on initiatives that improve quality of life. Community engagement is not an add-on to our work. It is central to who we are and how we operate.

Volunteering: Making Every Hour Count

126 employees. 1,650 hours. One community. That’s what impact looks like in the Copper Triangle. This year, our team showed up for food banks, flood cleanups, classrooms, and local events. They gave time, care, and heart. And it mattered.

2025 Year-End Review: Progress, Partnership, and Purpose

As 2025 comes to a close, Resolution Copper reflects on a year defined by progress, collaboration, and a shared commitment to doing things the right way. From major operational milestones underground to meaningful investments in local communities, this year marked another important step forward in responsibly advancing one of the most significant copper projects in the United States.

Breaking Ground for WMAT Youth Courts

On November 14, we joined the White Mountain Apache Tribe to celebrate the start of a project that came straight from community voices. WMAT leaders asked for more spaces where kids could safely play outside. We listened. Together we built a plan to rehabilitate three basketball courts. One in East Fork and two in Cibecue.

2025 Supplier Awards: The Partners Behind Every Shift

Once a year, we bring those stories into one room. Our Supplier Award Lunch is where we say thank you. Since 2019, this event has celebrated suppliers and community partners who live our values of care, courage, and curiosity. In 2025, we recognized six partners who quietly make a big difference for our teams, our project, and the Copper Triangle.

Building Community Through Sports

In November, Resolution Copper partnered with the Arizona Diamondbacks Baseball Academy to host a free baseball clinic in Whiteriver. Held at Alchesay High School, the event brought together more than 65 young athletes from the White Mountain Apache Little League. Players ages 6–14 spent the day learning from official D-backs coaches through drills, skills stations, and on-field instruction.
