Very bad idea. I support their measures to remove the preferential treatment and immunity their miners and extractors have enjoyed, but outlawry is moronic. I suspect this is nationalization through the back-door:

Morena and its coalition partners have approved a key exception to the proposed rules meaning that open-pit mining and fracking can be authorised “in rare cases determined by the federal Executive… due to their strategic importance for national development.”

So yeah, force sale of everything and then reissue permits. I'm sure DF will sink in their fangs as part of the deal.
