For decades, the mine and refinery at Mountain Pass dominated the rare earth industry. But then mining, processing, and magnet-making began moving to China. The mine shuttered at the turn of the millennium. A decade later, a new company tried to revive the business, but failed and filed for bankruptcy in 2015. James Litinsky was running a hedge fund when he saw an opportunity and set out to restore the mine. #rareearth #hedgefund #supplychain #criticalminerals
