Beyond defense, copper’s conductivity and corrosion resistance make it indispensable to public infrastructure, healthcare, and industrial systems. These are sectors with no viable large-scale substitutes. As global supply pressures and geopolitical risks intensify, strengthening domestic copper production remains critical to sustaining operational readiness, economic resilience, and industrial autonomy. 

4. Resolution Copper output and future growth 

The Resolution Copper project in Arizona is projected to supply up to 25% of future U.S. copper demand once operational. Located near Superior, Arizona, it represents one of the largest undeveloped copper deposits in the world and is strategically positioned to strengthen domestic supply while reducing reliance on imports. 

By 2030, Resolution Copper is expected to become a cornerstone of America’s critical minerals strategy, supporting the transition toward cleaner energy and advanced manufacturing. Its development, however, remains subject to rigorous environmental permitting, broad stakeholder engagement, and alignment with evolving EPA and GISTM compliance standards to ensure safe and sustainable operations.
