Resolution Copper awards $110 million contract for underground engineering and drilling

Resolution Copper has allocated approximately $110 million in service contracts to Major Drilling America and Redpath USA as part of a $500 million investment program in Arizona. The contracts cover deep-drilling exploration and subterranean shaft conversions, laying foundational infrastructure for one of North America's largest prospective copper deposits.

Underground pre-feasibility operations at the proposed Resolution Copper project in Arizona are accelerating following the commitment of approximately $110 million in contract awards to specialized engineering firms Major Drilling America Inc. and Redpath USA Corporation, according to official disclosures. The agreements represent a key operational milestone within an ongoing $500 million capital expenditure program aimed at completing deep exploration, shaft conversions, and subterranean facility development. Resolution Copper is a joint venture owned by mining groups Rio Tinto and BHP, created to develop one of the largest undeveloped copper deposits in North America near Superior, Arizona, with potential capacity to meet roughly a quarter of domestic US copper demand over a multi-decade operational lifespan.

Under the scope of the contracts, Major Drilling America will deploy high-capacity directional surface and subterranean diamond core drilling equipment, including advanced remote-controlled rigs equipped with automated rod handling systems designed to mitigate workplace hazards in deep hard-rock conditions. Concurrently, Redpath USA will initiate structural retrofitting across two existing 7,000-foot vertical shafts, transitioning them from sinking operations to active development configurations. This infrastructure phase entails installing structural steel framing, auxiliary maintenance bays, heavy machinery including Caterpillar loading units and production drills, and approximately 1,500 feet of underground tunneling at a depth of 6,800 feet below ground.

The expansion of technical field operations underscores a broader strategic effort to secure critical mineral supply chains in North America amidst rising demand for electrification materials, industrial energy infrastructure, and energy storage technologies. By advancing subterranean characterization and underground facility buildouts, the project partners aim to generate essential geotechnical and resource viability data required for final capital allocation decisions. Furthermore, the contract deployments are projected to create approximately 100 full-time direct positions alongside contractor roles, providing an economic stimulus to the local Arizona mining corridor while municipal, state, and environmental permitting evaluations remain underway.

Despite ongoing capital deployment, the project's ultimate commercialization remains contingent upon navigating complex regulatory approvals, environmental compliance assessments, state permitting frameworks, and consultations with Native American tribal communities. For mining investors and industrial equipment vendors, the project highlights both the growing capital intensity required to access deep-seated hard-rock reserves and the stringent safety and automation standards governing modern extraction initiatives. As global copper markets anticipate long-term structural supply deficits driven by the energy transition, the progress of large-scale greenfield assets in tier-one jurisdictions serves as a critical barometer for institutional investment in domestic critical mineral infrastructure.
