Resolution Copper awarded approximately $110 million [1] in contracts for exploration and underground development at its proposed Arizona mine on Aug. 7, 2026.
The investment signals a push to advance the technical viability of the site, which is located in the Copper Triangle near Superior, Arizona. This region sits roughly 60 miles east of Phoenix [2].
The contracts were awarded to Major Drilling America Inc. and Redpath USA Corporation [1]. These firms will handle the essential underground work required to further explore the copper deposits, and develop the infrastructure for the proposed operation [3].
Development of the mine is focused on advancing exploration efforts to better understand the scale and accessibility of the ore body. The project aims to secure a domestic source of copper, a critical metal for electronics and green energy infrastructure, within the U.S. [3].
The $110 million [1] allocation covers a range of specialized mining services. Redpath USA and Major Drilling America are tasked with executing the complex drilling and excavation work necessary to move the project toward full-scale production [3].
Resolution Copper continues to navigate the development of the site in the Copper Triangle. The current phase of underground work is a prerequisite for establishing the mine's long-term operational footprint [2].
“Resolution Copper awarded approximately $110 million in contracts for exploration and underground development.”
The allocation of significant capital for underground development indicates that Resolution Copper is moving from theoretical planning into active physical preparation. By engaging specialized firms like Redpath and Major Drilling, the company is addressing the technical challenges of deep-earth extraction, which is necessary to prove the mine's economic feasibility amid fluctuating global copper demand.
