I don’t want to say this happens ‘a lot’ but it’s not uncommon. I have a site on my roster where they re-mined their tailings for beryllium… in the 80s. That said, while remining does happen, we need to be careful of buying into greenwashing and the argument that since a couple mines have had success with remining, that it is sufficient reason not to conduct progressive reclamation or advance closure efforts. A lot of mines have not planned for closure, and 70% of mines do not complete their mine plan (in that they sell to someone else or go bankrupt, resulting in an abandoned mine).
