Yeah interesting, it sounds like a group I heard about via newswire recently about Phoenix Tailings and their funding from Yamaha and BMW, an excerpt from the first article and some links below.

""The company will use the funding to build a $13 million facility in Exeter, New Hampshire, that can produce 200 metric tons of rare earths annually and should open by June 2025, Myers said.

The remaining funding will be used for research, engineering and business development.

The Massachusetts-based company, which has 33 employees, says it has signed supply contracts worth more than $100 million, although it declined to say with whom. If the Exeter facility is successful, Phoenix plans to build larger processing facilities elsewhere in the U.S.""
