What I can see:

2013 POET issued 14.400.000 of these 0,75 CAD warrants which will be due next week.
End of 9/2014 there were 10.168.000 left, so since then until next week POET should have collected about 7,5 Mio CAD - assuming that all the warrants will be exercised. Since 9/2014 the total issued shares went up by 7,8 Mio (makes about 6 Mio CAD cash if they were the 0,75 warrants).
We do not know how much POET spent since then. So we just have to wat for their annual report. The last statement of POET: 8 Jan 2015:

“Although we spent on outsourcing and capital equipment through 2014, we start the new year with a cash balance of approximately $12.5 million"

So it is obvious that today their cash is significantly higher.
