The U.S. army is hungry for a home provide of tungsten, a vital mineral used to make weapons—however a NASA facility successfully blocks mining of an enormous deposit of the heavy metallic in Nevada, based on a Monetary Instances report.
The deposit is situated in an space of the Nice Basin Desert in jap Nevada and will include nearly two million metric tons of tungsten. Mining firm 3 Proton Lithium (3PL) needs to develop the location, however round a 3rd of it’s situated in lands reserved for NASA to make use of for calibrating Earth-observing satellites. The pristine wilderness permits the area company to fine-tune devices onboard these spacecraft to make sure they make correct measurements.
NASA has used the realm, referred to as Railroad Valley, for this goal for a minimum of 33 years. And in 2023 the Bureau of Land Administration formally granted NASA unique use of the about 92 sq. kilometers (22,634 acres)—blocking every other public or non-public use.

On the time NASA described Railroad Valley as “uniquely suited” for its functions due to a dry lake mattress that was “giant, flat, freed from vegetation, of a constant floor coloration, undisturbed, simple to entry, and with good visibility from area.”

The largely featureless panorama is essential as a result of NASA technicians know precisely how a lot mirrored mild satellites’ optical devices ought to see within the space. Among the many missions that use the land are Landsat, which screens Earth’s land and water assets; Suomi NPP, a climate and local weather statement platform; and the Earth Floor Mineral Mud Supply Investigation (EMIT), which maps the composition of arid mud that blows across the planet.
This isn’t the primary time 3PL has tried to use this land: a beforehand discovered lithium deposit arrange a doable battle with the area company in 2023—and NASA received. In a assertion concerning the new deposit that was launched on Monday, 3PL mentioned it has estimated that its declare comprises 31 million tons of lithium carbonate equal; if confirmed, that might make it among the many largest lithium assets in North America. The location additionally consists of giant quantities of boron and potash, 3PL mentioned. The latter is a salt that’s typically used to make fertilizer, which the U.S. nearly solely imports.
“We now have a measured, world-class deposit of a number of vital minerals in a single basin, and the one discovery that shocked even us is tungsten,” mentioned 3PL chairman and chief monetary officer Kevin Moore within the assertion. “This can be a metallic america stopped mining a decade in the past and now imports whereas China controls and manipulates the worldwide market. To seek out extra of it right here than wherever, alongside giant, measured lithium, potash, and boron at world-class grade, will not be a mining story. It’s a nationwide safety story.”
Tungsten’s usefulness stems from its resilience to warmth: it has the best melting and boiling level beneath typical situations of any component, which made it good to be used in older generations of mild bulbs. It additionally has the best tensile power of any metallic and is denser than lead; these qualities make it preferrred a really perfect materials for making weapons. The necessity for tungsten has grow to be much more urgent due to the continuing conflict with Iran, which has seen the U.S. hearth off giant quantities of munitions that include the metallic, akin to Tomahawk missiles.
Regardless of its significance to the army, the U.S. has lengthy lagged in manufacturing of the fabric. A February report from the U.S. Geological Survey confirmed that the nation produced a negligible quantity of the fabric in 2024 and 2025. In contrast, China’s mines produced 67,000 metric tons of tungsten in every of these years, accounting for nearly 80 p.c of worldwide manufacturing.

I’ve been a Scientific American subscriber since I used to be 12 years outdated, and it helped form the best way I have a look at the world. SciAm all the time educates and delights me, and evokes a way of awe for our huge, lovely universe. I hope it does that for you, too.
In case you subscribe to Scientific American, you assist make sure that our protection is centered on significant analysis and discovery; that now we have the assets to report on the selections that threaten labs throughout the U.S.; and that we assist each budding and dealing scientists at a time when the worth of science itself too typically goes unrecognized.
In return, you get important information, fascinating podcasts, good infographics, can’t-miss newsletters, must-watch movies, difficult video games, and the science world’s finest writing and reporting. You possibly can even reward somebody a subscription.
There has by no means been a extra vital time for us to face up and present why science issues. I hope you’ll assist us in that mission.
