Ann: Clarke - Rare Earth Identified Above Gold Mineralisation, page-32

What also is important here (and we don't know yet) is what rare earths are there. REEs is a catchall term for lots of rare earth elements. Some rare earths are completely useless, others are highly important and lucrative.
In about a years time everyone will start to get some idea of widths and grades and impurities and which rare earths are present, etc, etc , etc.
There will undoubtedly be areas of REE concentration in the Poochera district as well. Maybe Mt Hope? Whereever there is kaolin there is a chance of REE concentration. With huge swathes of ground you would expect some half significant zones of that concentration somewhere. You would also expect ADN to simply come across it almost by chance while defining it's numerous H-k orebodies.
