Check my understanding here: It’s not that they’re scarce, but there’s no geological process that concentrates them like copper or gold. There aren’t any neodymium seams the way there are gold seams, there’s a very little amount everywhere. So you might as well sift the entire Mojave.

Yeah there’s a reason people were saber rattling over those offshore deposits Japan claimed, and it’s not because undersea mining is cheap and efficient or “they’re on every continent what’s the big deal”
