Hi Fergus,
I think it has been announced that it works!!! A bit subtle but still finally confirmation. This from page 6 of the Annual Report.
"At the time of writing, the Demonstration Plant is producing high grade synrutile and iron pellets".
So all the technologies are now proved to be working at a commercial scale. They just need to make sure it's consistent before they report but I've had my "YES" moment.
Cheers
Seik
