US 3 Proton Lithium announced the discovery of the largest tungsten deposit in the US. The deposit has reserves of about 1.78 million tons, far exceeding the current second-largest tungsten ore reserves in the US. 3PL believes its value is about 152 billion US dollars. However, NASA applied to the US Federal Bureau of Land Management (BLM) for a ban on mining and exploration in the region on the grounds that the region involved space missions, and prevented 3PL from carrying out large-scale mining here. According to reports, the 3PL has raised nearly 50 million US dollars to lobby the Trump administration and Congress to overturn the ban.
