The deal comes as manufacturers of wind turbines using direct-drive permanent-magnet generators (PMGs) scramble to lock-down supplies of the rare-earth metal neodymium needed for the machines.

Lynas owns the mining rights at Western Australia’s Mount Weld, which holds one of the world’s richest deposits of rare-earth metals.
