POET can also call in the warrant money, post big news; there's $18M CAD to be un-locked.

I admit I haven't been looking at the warrants.   Can you expand on the $18M CAD to be unlocked?   What do you mean "call in"?

The warrants issued in the last PO had an expiry date of 5 years.   From that PO there are 35 million outstanding, at a price of .52c, so they are not "in the money".    On the one hand, not looking forward to the share dilution with another 35 million new shares trading, but on the other hand, it would be an improvement in the share price.
