ioneer/Rhyolite Ridge

A federal judge in Nevada granted summary judgment to the Interior Department and the Bureau of Land Management, rejecting environmental groups' challenge to the mine approval. The court found the agencies had reasonably concluded the project would not jeopardise the endangered Tiehm's buckwheat.

• Judge Cristina D. Silva, US District Court.
• Claims under the Endangered Species Act, NEPA and the federal land-management law were all rejected.
• Opponents appealed to the Ninth Circuit on 9 April 2026; ioneer expects a ruling in mid-2027.
