NASA's Nevada Site Blocks Access to Critical Tungsten Deposit for US Defense Industry
A satellite calibration area stands in the way of a vital tungsten reserve needed for military applications.
1Strategic importance of tungsten
Tungsten plays a critical role in defense industries due to its high melting point and durability. Used in munitions like Tomahawk missiles, the metal has gained special significance during the ongoing conflict with Iran. While China controls 80% of global tungsten production, US output remains negligible. This makes the newly discovered Nevada deposit a national security issue.
2Railroad Valley's significance for NASA
NASA has used Railroad Valley for satellite calibration for 33 years. The 92-square-kilometer area's flat, vegetation-free terrain makes it ideal for space-based measurements. Missions like Landsat and EMIT monitor Earth's resources using this site. In 2023, BLM granted NASA exclusive rights, blocking mining activities in the area.
33 Proton Lithium's discovery
3PL discovered 2 million metric tons of tungsten alongside 31 million tons of lithium carbonate equivalent in the region. This could become one of North America's largest lithium resources. The company also reported significant boron and potash deposits. Potash, nearly entirely imported by the US, is crucial for fertilizer production.
4Previous conflict and NASA's victory
In 2023, 3PL's lithium discovery led to a similar dispute with NASA. The space agency successfully blocked mining to preserve scientific work. The new tungsten find raises the possibility of renewed conflict. NASA hasn't yet commented on recent developments regarding the mineral deposit.
5Global tungsten market dynamics
According to USGS reports, China produced 67,000 metric tons of tungsten annually in 2024-2025, while US production remained minimal. China's market control causes price fluctuations. Nevada's deposit could reduce US dependence on Chinese tungsten, strengthening defense supply chains.
6Environmental and scientific concerns
Railroad Valley's pristine conditions are vital for satellite calibration. Mining could alter reflectance properties, disrupting climate and land monitoring. NASA officials call the site the 'gold standard' for Earth observation systems. 3PL claims mining can be conducted with minimal environmental impact.
7National security implications
3PL CFO Kevin Moore calls the discovery a 'national security story.' Resuming tungsten mining, halted a decade ago, could strengthen defense supply chains. Dependence on China for missile components poses strategic risks. The deposit's size offers the US a chance to achieve self-sufficiency in this critical material.
8The dilemma and potential solutions
The US faces a tough choice between scientific progress and defense needs. Experts suggest controlled mining in parts of the area or finding alternative calibration sites. The decision will reflect budget priorities between defense and science. Congressional action is expected to address this complex issue.
