First, in Arizona, the U.S. Forest Service and Resolution Copper have finalized a long-awaited federal land exchange. The joint venture between Rio Tinto and BHP now moves closer to development after a favorable ruling from the Ninth Circuit Court of Appeal. The deal transfers more than 5,000 acres of environmentally and culturally sensitive land into federal protection, while granting Resolution Copper access to over 2,400 acres near the historic Magma mine. Company leaders say the project could generate thousands of jobs and contribute roughly $1 billion annually to Arizona’s economy. The company also plans to invest an additional $500 million in early-stage work, signaling momentum as the project enters its next phase.
Next, the U.S. Department of Energy has announced up to $500 million in new funding aimed at expanding domestic processing, recycling and manufacturing of critical battery materials. The initiative, led by the U.S. Department of Energy, targets key minerals such as lithium, graphite, nickel and copper. Officials say the funding will support both demonstration and commercial-scale facilities, with a focus on strengthening supply chains that have long depended on foreign sources. The announcement comes as U.S. energy leaders engage with international partners, including meetings in Japan focused on Indo-Pacific energy security. The program marks the third round of federal investment in battery materials and reflects a broader strategy to boost domestic production capacity.
Finally, the U.S. is in ongoing discussions with Brazil to secure access to critical mineral supply chains, even as diplomatic tensions complicate negotiations. U.S. officials have directed hundreds of millions of dollars in financing toward mining projects in the country. However, recent friction between the two nations has slowed progress on a federal-level agreement. In the meantime, the U.S. has moved ahead with a separate deal with the state of Goiás to boost mineral development and expand processing capabilities. The region holds key assets, including rare earth operations backed by international investment Despite the political hurdles, both sides continue to signal interest in deeper cooperation as demand for critical minerals accelerates worldwide.
