Biden administration over a Nevada lithium mine, environmentalists are poised to return to court with a new approach accusing US wildlife officials of dragging their feet on a year-old petition seeking endangered species status for a tiny snail that lives nearby.
The Western Watersheds Project said in its formal notice of intent to sue that the government's failure to list the Kings River pyrg as a threatened or endangered species could push it to the brink of extinction.
It says the only place the snail is known to exist is in 13 shallow springs near where Lithium Americas is building its Thacker Pass Mine near the Oregon line.
US President Joe Biden has made ramped-up domestic production of lithium a key part of his blueprint for a greener future.
