Environmentalists filed an appeal Wednesday of a district court ruling that paves the way for a lithium mine in Nevada that they say will destroy the habitat of an endangered desert wildflower.

The Center for Biological Diversity and several other groups appealed U.S. District Judge Cristina Silva’s finding that the federal government had complied with the law in approving Ioneer’s planned open-pit lithium and boron mine and processing plant in Esmeralda County.

The groups appealed the ruling to the 9th U.S. Circuit Court of Appeals.

Silva, a former federal prosecutor and a Biden appointee, found that the Bureau of Land Management complied with the Endangered Species Act and National Environmental Policy Act when approving the project.
