Copper is the gateway to strategic and critical minerals

While Resolution Copper will be one of the largest copper mines in the United States, the mine will also be a tremendous source of other strategic and critical minerals that are essential to helping the United States enable the energy transition domestically.

State of critical minerals

Domestically mined and refined strategic and critical minerals are needed for the United States to reach its clean energy goals, bolster supply chain resiliency, and boost national security. However, the United States is currently heavily reliant on imported critical minerals at a time when the world is transitioning to a clean energy economy. Although global demand for critical minerals is set to skyrocket by 400-600 percent over the next several decades,1 the United States is increasingly dependent on foreign supplies for many of the processed versions of these minerals.

Resolution Copper is part of the solution.

Overseas development and dominance of the critical mineral industry places the United States at a strategic disadvantage, and projects like Resolution Copper are needed to meet current needs and future demands.

In addition to copper, Resolution Copper will also be a tremendous source of other strategic and critical minerals. Resolution Copper can be a domestic source of at least seven other strategic and critical minerals that are found in the mine’s deposit. These minerals can be used in a variety of materials and technologies ranging from semiconductors to solar panels to electric vehicles; all of which are essential to the clean energy transition and national security.

Superior’s role in the energy transition

Resolution Copper is more than a mine. It’s a team of dedicated people working toward the common goal of providing the strategic minerals and metals needed to power everyday life.

Resolution Copper is made up of people who live and work in the Copper Triangle, Copper Corridor, and nearby tribal communities. We are proud that the town of Superior, Arizona is playing such an important role in supplying the critical materials needed for United States national security and the energy transition.

Inside the Never Sweat Tunnel

Completed in 1973 by the Magma Copper Company, the Never Sweat Tunnel stretches 8,600 feet (1.6 miles) long and sits at a depth of 1,100 feet. At the time, it came with a hefty price tag of $74 million, but what it delivered was priceless. It created a direct underground connection between the East and West Plant sites.
