WASHINGTON, D.C. – U.S. President Donald Trump hosted Rio Tinto CEO Jakob Stausholm, incoming CEO Simon Trott, and BHP CEO Mike Henry at the Oval Office on Tuesday to discuss the future of Resolution Copper, a joint venture between the two mining majors that promises to be one of North America’s largest copper mines.
The meeting came just hours after the U.S. Ninth Circuit Court of Appeals issued a temporary injunction blocking the transfer of federal land in Arizona to the miners, following appeals by the San Carlos Apache tribe and environmental groups.
Resolution Copper has long been promoted as a $1 billion-per-year economic engine for Arizona, with the potential to supply up to 25% of projected U.S. copper demand once in full production. Yet two decades after its discovery, the project remains locked in a tug-of-war between Washington’s mineral security ambitions and tribal, cultural, and environmental opposition.
Copper Security Meets Cultural Rights
President Trump framed the injunction as a setback to U.S. mineral security, calling opponents “radical left activists” and accusing them of representing “other copper competitive countries.” He argued the project would create “thousands of jobs” and bolster U.S. control over a metal central to the energy transition, power grid modernization, and defense technology.
For BHP and Rio Tinto, the stakes extend beyond Arizona. Copper demand is forecast by the International Energy Agency (IEA) to nearly double by 2040 under net-zero scenarios, with electrification and renewables driving consumption. Western miners, already facing supply constraints in Chile and permitting delays elsewhere in North America, view Resolution Copper as a cornerstone asset in reshaping global supply chains.
But Oak Flat, the 2,400-acre tract east of Phoenix where the mine is planned, holds deep religious and cultural significance for the San Carlos Apache and other tribes. For generations, the site has hosted ceremonies, prayers, and the collection of medicinal plants.
Legal and Regulatory Stalemate
The injunction underscores a broader conflict over how U.S. agencies manage mineral projects on federal land. Plaintiffs argued the Forest Service’s review failed to assess risks such as potential dam breaches, pipeline failures, or tailings storage failures. They also contested the land appraisal, claiming it excluded the economic value of copper reserves buried 5,000 feet underground.
Resolution Copper counters that the mine has undergone two decades of federal review, including consultation with tribes, which led to modifications in the mining plan to reduce impacts. The Forest Service maintains that Congress mandated the land exchange in the 2014 National Defense Authorization Act, leaving the agency with little discretion.
The Ninth Circuit has yet to set a date for full arguments. Until then, the project remains paused—adding further uncertainty for investors already weighing U.S. political and permitting risks against long-term copper fundamentals.
Industry and Investor Implications
Mike Henry of BHP described the mine as “billions in economic activity across America” and reiterated the company’s confidence in the courts upholding the land exchange. Rio Tinto, which owns a 55% stake, echoed the sentiment, stressing the injunction is “merely a temporary pause.”
Analysts point out that for U.S. copper supply, the pause collides with wider market pressures. Recent tariffs on semi-finished copper imports have already reshaped North American supply chains. With U.S. grid expansion and EV demand accelerating, any delay at Resolution amplifies reliance on imports from Latin America and Africa, regions where geopolitical and environmental risks remain elevated.
Skillings Analysis
- Strategic Gap: “Resolution Copper is emblematic of the U.S. mineral paradox—demand for critical minerals rising fast, but projects face decades-long opposition.”
- Investor Lens: “While Rio Tinto and BHP can absorb delays, mid-tier U.S. copper developers face tougher investor scrutiny on permitting risks.”
- Policy Signal: “This case may set a precedent: if a congressionally mandated land swap can be stalled in courts, no U.S. copper developer can take land certainty for granted.”
Looking Ahead
The appeals court’s decision later this year will be pivotal. A ruling in favor of Resolution could restart land transfer and push the project toward permitting. A ruling against could embolden opponents of other U.S. mineral projects.
For mining investors and analysts, the outcome ties directly to copper’s forward curve. As utilities scramble to contract supply and U.S. policy seeks domestic mineral security, Resolution Copper sits at the intersection of politics, economics, and environmental stewardship.
As winter demand and the U.S. election cycle converge, Resolution Copper will remain a litmus test for how Washington balances energy transition priorities with Indigenous and environmental rights.
