The Timbisha Shoshone Tribe and a coalition of conservation groups have hauled the federal government into court, filing a lawsuit Wednesday to stop exploratory drilling for a zeolite deposit near Ash Meadows National Wildlife Refuge. They argue the Bureau of Land Management signed off on a plan to sink boreholes near springs and wetlands that feed the refuge’s delicate groundwater system, putting rare plants and culturally important sites in the crosshairs.
What the lawsuit says
In a complaint outlined by the Center for Biological Diversity, plaintiffs say the U.S. Bureau of Land Management illegally approved St. Cloud Mining’s exploration plan without following the Endangered Species Act. The lawsuit, brought by the Timbisha Shoshone Tribe, the Center, and the Amargosa Conservancy, asks a federal judge to toss out the BLM authorization and halt any drilling until the agency completes required environmental reviews and formal consultations.
Drilling plan and groundwater risks
Federal approvals allow St. Cloud to drill 43 exploratory holes, each up to 200 feet deep, on public land near the refuge. Agency documents note the water table in the area sits at roughly 100 feet, which means some of those holes are likely to intersect groundwater, according to reporting by the Nevada Current. Hydrologists cited in the dispute say there is major uncertainty about how the aquifer connects to Ash Meadows’ springs, and the complaint warns that hitting pressurized zones could drain or disrupt wetlands that support species found nowhere else on Earth.
Species and cultural stakes
The lawsuit singles out three federally protected plants that depend on groundwater-fed springs around Ash Meadows: the Amargosa niterwort, the Ash Meadows gumplant and the spring-loving centaury. All could be threatened if aquifer levels drop, according to the Las Vegas Review-Journal. The Timbisha also argue that BLM failed to adequately consult the tribe under the National Historic Preservation Act, turning the fight into one about cultural and religious survival as much as biology.
What they want to mine and why it matters
St. Cloud is after clinoptilolite, a natural zeolite used in everything from animal feed additives and odor-control cat litter to water filtration and some cleanup work. Universities and extension services have documented the mineral’s cation-exchange and adsorption abilities, which make it useful in agriculture and industry; see the University of Arizona Cooperative Extension for a summary. Environmental groups counter that the local water and species at stake are far more valuable than a relatively low-value mineral play, and Patrick Donnelly of the Center for Biological Diversity warned in a statement that “Ash Meadows is too special to drill.”
Mineral withdrawal and what's next
Federal land managers have already moved to rein in new mining across the broader Amargosa Basin. The Bureau of Land Management has started a mineral-withdrawal process that would pause new claims while the agency studies potential impacts, although the St. Cloud project site sits just over the California state line and may fall outside that proposed withdrawal area, according to The Nature Conservancy. Plaintiffs are asking the court to set aside the current BLM approval and block any new authorization until Endangered Species Act consultations are complete, and the case will decide whether the agency’s review passes legal muster or whether drilling has to stay on ice, the Las Vegas Review-Journal reported.
Local reaction and next moves
As the lawsuit advances, conservation advocates and county officials say they will keep pressing for tougher, long-term protections for the basin. “A broad and powerful coalition rose up once to save Ash Meadows, and now we’re mobilizing again,” Mason Voehl, executive director of the Amargosa Conservancy, said in a statement from the Amargosa Conservancy.
