Could be that they produce sulphate 50:50 which is then 100% purchased by RBW for further processing to metal in the USA.
There maybe 3 more mines which are follow on projects. This first one was chosen as proof of concept, its almost identical to Phalaborwa, if significantly bigger . The RE content varies significantly on the others, it's in the link I posted earlier.
And there are still more potential targets around the world.
