I'm a long term speculative holder (yer, that's worked out well for me so far!). Does anyone have any comments about the likely profitability of this co? How much is it likely going to cost to mine per oz? How much can it be sold for presently - I'm told there is over supply?

It's great to have a a valuable resource but if costs to extract and get it to a flooded market are too high compared to the going buy price, what's it really worth (at the moment)?

I have some knowledge (through pain) about the IO sector but none for REEs.
