Ann: Trading Halt-PIO.AX, page-112

I think we should not get ahead of ourselves and wait for the results to come through before speculating on the the SP. I am hoping that the results will be beyond what they expected and we have a very good SP rise.

I just don't want to count my chickens before they are hatched. I did with DKO and look where that has ended up, even though I did make a profit, luckily.
I'm no geologist or miner but I am hoping that someone that is or has good knowledge of the said fields can inform me of a questions.

1: If they have great results what would make it too expensive to mine.
2: What depth's would the lithium be viable to extract. IE do they have a cut off depth in which it is reasonable to extract or doesn't it matter
