Can someone please explain why GXY would be interested in A40. Extension of Mt Cattlin production from Bald Hill ore? I get that but......

The current A40 Li2O grades are pretty low (0.76-0.81).
Is there higher grade ore hiding in those hills than what A40 has been digging up at a huge expense?

A40 mined 2Mt of dirt to produce 38kt of spod with a strip ratio of 10-15!!!!
GXY mined half that material (1.2Mt) with a strip ratio of 2.5 to produce 50kt!!!

There is IMHO no point using Bald Hill ore (<1%Li2O)  for processing at Mt Cattlin. Mt Cattlin Q3 grades reduced from 1.40 (Q2) to 1.18 and that seemed to have increased production costs by US$50 (+15%). How much will production costs go up with lower grades...and also negatively affect recovery?

Or is GXY interested in the tantalum processing?

I just don't get it. I must have missed some A40 drilling results of high grade Li2O.
