Should mining projects be permitted within protected national preserves?

Judge Christina Snyder ordered a temporary halt to the Colosseum Mining Project within the Mojave National Preserve. The ruling pauses development while the federal government pursues an appeal in the Ninth Circuit.

Why it matters

The court raised concerns regarding whether the project record sufficiently justifies claims that the mine is necessary for national-security interests. This decision directly impacts the future of industrial activity within protected federal lands.

The ruling affects mining operations located specifically within the Mojave National Preserve in California. The legal challenge stems from a lawsuit filed in April 2026 regarding oversight of the site.
