Alaska remains a potential source for critical rare earth elements as trade dispute with China escalates
https://www.adn.com/business-economy/2018/08/03/alaska-remains-a-potential-source-for-critical-rare-earth-elements-as-trade-dispute-with-china-escalates/Rare earth elements really aren't that rare; they're just rarely mined.
Many in Washington, D.C., particularly those in the Defense Department, see this as a major looming issue....
...As seems to be the case with most mineral commodities, Alaska holds its own rare earth resources.
The most notable deposit is the Bokan Mountain prospect that Nova Scotia-based Ucore Rare Metals Inc. explored until 2015. The prospect on southern Prince of Wales Island is approximately 40 percent heavy rare earths, according to Ucore, which are the hardest to come by. Overall, it holds roughly 5 million tons of ore with rare earth concentrations of 0.65 percent, according to the company.
Kreiner said rare earths occur across the state but the viability of mining them other places is largely unknown simply because they haven't been explored.
"Bokan Mountain is the only quote-unquote deposit in Alaska. So whether it's a deposit or an occurrence is really an economic definition. Basically, it becomes a deposit when it's concentrated to the point that it can be extracted," he said....

Alaska's rare earth deposits and resource potential
https://pubs.er.usgs.gov/publication/70044949Alaska’s known mineral endowment includes some of the largest and highest grade deposits of various metals, including gold, copper and zinc. Recently, Alaska has also been active in the worldwide search for sources of rare earth elements (REE) to replace exports now being limited by China. Driven by limited supply of the rare earths, combined with their increasing use in new ‘green’ energy, lighting, transportation, and many other technological applications, the rare earth metals neodymium, europium and, in particular, the heavy rare earth elements terbium, dysprosium and yttrium are forecast to soon be in critical short supply (U.S. Department of Energy, 2010).....
