China views rare earths as a national treasure, says American Elements CEO Michael Silver

Geopolitical & Supply Chain Concerns - China's restriction on rare earth mineral exports is viewed as a threat to the global supply chain [1] - China restricted seven rare earth materials initially, and added five more recently [3][4] - These restricted rare earths, critical for commercial and military tech, constitute only about 1% of a rare earth deposit [4] - The move may indicate China's intention to retain these materials long-term, potentially impacting the US [5] - China may be using rare earth restrictions as leverage in trade disputes [6] Market & Economic Impact - China's potential reduction of serium, lanthanum, neodymium, and praodmium prices (the bulk of rare earth deposits) could negatively impact the profitability of new and existing rare earth mines [8] - This could necessitate US government subsidies to maintain operations like the Mountain Pass mine [8][9] - Restrictions will impact electric car production due to the use of dysprosium in neodymium boron magnets [16] - China has historically manipulated rare earth pricing to achieve strategic goals, including attracting foreign investment [16] US Response & Strategic Considerations - The US government may need to subsidize the Mountain Pass mine to secure turbium, dysprosium, scandium, and yttrium, essential for military technologies [10] - The US possesses sufficient heavy rare earth deposits to support military applications, particularly from Mountain Pass and Lionus' Mount Weld mine in Australia [13] - Government involvement and subsidies are likely needed to develop domestic rare earth resources in Wyoming, Alaska (UKORB site), and potentially Greenland [19] - There's a trend towards sovereign control over these materials [19]
