As stakeholders navigate competing priorities, the project's future remains uncertain amid ongoing legal challenges and passionate advocacy from various groups.
What is the Resolution Copper Project?
Overview of the Proposed Mine
The Resolution Copper project represents one of America's largest untapped copper resources, located at Oak Flat in Arizona. This massive mining venture is structured as a joint venture between Rio Tinto, which holds a 55% ownership stake, and BHP, which maintains the remaining 45% ownership. According to industry reports, the project is projected to produce approximately 20 million tonnes of copper over a 40-year operational lifespan.
Development plans have been in motion for more than a decade, with substantial investments already made in exploration, environmental studies, and community engagement. The project would employ block cave mining techniques, a method that allows for extraction of ore bodies at greater depths than traditional open-pit mining.
BHP CEO Mike Henry has described Resolution as "one of the largest untapped, high-grade copper resources in the U.S., with the potential for thousands of high-value local jobs and billions in economic activity," highlighting the economic significance of the project to both the companies and the region.
Strategic Importance in the Global Copper Market
Resolution Copper is positioned as a critical domestic source of copper amid growing global demand for this essential mineral. The United States currently imports approximately 35% of its copper needs, making the development of major domestic sources a matter of economic and strategic importance.
The copper from this project would support numerous industries critical to American manufacturing, including:
- Electric vehicle production
- Renewable energy infrastructure
- Electronics manufacturing
- Construction
- National defense applications
Rio Tinto has emphasized its "150-year history in the US" as "a significant producer of copper, as well as lithium, tellurium, gold, silver, molybdenum, borates, and recycled aluminium," underscoring the company's role in domestic mineral production.
With copper price predictions showing significant increases in coming decades due to electrification and renewable energy transitions, the Resolution project's potential to significantly strengthen U.S. copper production capabilities becomes increasingly relevant in discussions about mineral security and supply chain resilience.
Why is the Resolution Mine Facing Opposition?
Sacred Land Controversy
At the heart of opposition to the Resolution Copper project is the sacred nature of Oak Flat (Chi'chil Biłdagoteel) to the San Carlos Apache and other Native American tribes. This site holds profound cultural and religious significance for indigenous communities who have utilized the area for ceremonial purposes for countless generations.
Tribal representatives have consistently maintained that the mine would permanently destroy irreplaceable cultural heritage sites, including:
- Ancient burial grounds
- Traditional ceremony locations
- Sacred springs and water sources
- Historically significant gathering places
- Areas central to oral traditions and tribal identity
Opposition centered on protection of ancestral lands and religious practices has united multiple tribes in their resistance to the project. Many tribal members view the potential destruction of Oak Flat as not merely an environmental issue, but an existential threat to their cultural continuity and religious freedom.
Environmental Concerns
Beyond cultural preservation, environmental groups have joined indigenous opposition citing potential ecological impacts that could extend far beyond the mine's operational footprint. Chief among these concerns is groundwater contamination and depletion in an already water-stressed region.
Environmental advocates point to several specific risks:
- The creation of a substantial subsidence crater that could be up to 1,000 feet deep and nearly 2 miles wide
- Potential contamination of groundwater with heavy metals and processing chemicals
- Disruption of wildlife corridors and habitat fragmentation
- Permanent alterations to the landscape and ecosystem
- Air quality impacts from mining operations and increased traffic
Questions about long-term mine reclamation innovations have further fueled opposition, with critics arguing that the projected economic benefits don't outweigh the permanent environmental costs that would persist long after the mine's operational lifespan concludes.
What Legal Challenges is the Project Facing?
Recent Court Decision Impact
A significant setback for the Resolution Copper project came with a recent U.S. court ruling that delayed a crucial land exchange necessary for project advancement. This land swap would transfer 2,422 acres of federally protected land to the mining companies in exchange for other parcels.
The court decision represents a significant impediment to the project timeline, as without the land exchange, the project cannot proceed as designed. While mining advocates view this as a temporary obstacle, opponents have celebrated it as a victory in their fight to permanently protect Oak Flat.
A Resolution spokesman characterized the ruling as "merely a temporary pause," adding that "We are confident the court will ultimately affirm the district court's well-reasoned orders." This statement reflects the company's determination to pursue legal remedies and continue advancing the project despite current obstacles.
Legislative and Regulatory Hurdles
Beyond the immediate court challenge, the copper controversy in resolution mine faces a complex web of legislative and regulatory requirements. The project requires approval from multiple federal agencies, including the U.S. Forest Service, Bureau of Land Management, Army Corps of Engineers, and Environmental Protection Agency.
The environmental impact assessment process has faced repeated challenges, with critics arguing that:
- Tribal consultation was inadequate and failed to properly consider cultural impacts
- Water usage projections were underestimated
- Wildlife protection measures were insufficient
- Long-term environmental monitoring plans lacked specificity
- Reclamation plans did not adequately address permanent landscape changes
Land exchange legislation has been contested through various legal channels, and ongoing litigation from tribal and environmental groups creates significant uncertainty for the project's timeline and ultimate viability.
How Are Key Stakeholders Responding to the Controversy?
Mining Companies' Position
Rio Tinto and BHP have maintained a steadfast commitment to advancing the Resolution Copper project, emphasizing its economic and strategic benefits while pledging to operate responsibly. In a significant demonstration of the project's importance, executives from both companies, including Rio CEO Simon Trott, outgoing boss Jakob Stausholm, and BHP's Mike Henry, met with President Trump to discuss obstacles facing the project.
