U.S. Hits New Obstacle on Critical Mineral Security Course

The article says the U.S. faces a setback in its push to secure critical minerals domestically after NASA objected to further development of a major tungsten discovery in Nevada. NASA argues mining could interfere with satellite signal tracking in the remote Great Basin area, even though the deposit may be the largest tungsten find in the U.S. The issue underscores the tension between national security goals, resource development, and infrastructure/spectrum constraints. Tungsten is strategically important for electronics, defense, and aviation, and the discovery is estimated at 1.78 million tons and $152 billion in value. The conflict comes as China controls about 80% of global tungsten supply and export limits have helped drive prices up sharply, highlighting why Washington wants to reduce reliance on China. Near-term market impact is mainly on the tungsten/critical minerals theme rather than broad markets, but it reinforces bullish supply-side pressure for strategic metals.
