No Mine Produces It. Every Gram Is Born in a Reactor.
Promethium is the only radioactive rare earth. The world produces under 100 grams per year. Now it is on-chain.
Promethium is the only rare earth with zero stable isotopes. It cannot be mined. It decays from the moment it is created. Supply is governed by physics, not economics.
