It still feels so disingenuous, too, that this keeps coming up for Cobalt, specifically. Cobalt had centuries of being "the useless junk that makes a pretty blue paint from our tin mines". These mines are certainly not mining just for Cobalt any more now that rechargeable batteries are an important thing to some cars. They are still mining tin, lead, diamonds, gold, etc and getting some amount of Cobalt out as a side hustle or "waste product".
