Overview

  • A Ninth Circuit panel issued a temporary injunction late Monday, stopping a transfer that had been scheduled for Tuesday.
  • The order responds to late challenges from the San Carlos Apache Tribe and environmental groups alleging religious, cultural, environmental, and safety harms under incomplete reviews.
  • Resolution Copper, a Rio TintoBHP venture, called the ruling a temporary pause and said an 11-year Forest Service process meets all legal requirements.
  • President Trump denounced the decision on Truth Social after meeting the chiefs of Rio Tinto and BHP with Interior Secretary Doug Burgum at the White House.
  • Plaintiffs seek a comprehensive assessment covering tailings storage, dam‑breach contingencies, pipelines, and other infrastructure before any transfer proceeds.
