Back in Oct 2013

I don't necessarily like to harp back to the old days, but this was published 2nd October 2013, and has always stuck in my mind. http://www.asx.com.au/asxpdf/20131002/pdf/42jrtxfq6380jz.pdf

It states

"Cash Flow of $48M after Capital Repayment at US$110, (IRR 114%.) [3]
[3] = Undiscounted at US$110 based on sliding range starting at USD$1 : 90c AUD, to 0.82AUD."

So currently IO is around US$80 and exchange rate at 0.73c.  80/0.73 = A$110.

Surely its got to be worth some sort of current feasibility?

AGO seems to be back from the dead, surely there should at least be some sort of high level cursory glance with an update to market to at least say, it was looked at and a) doesnt stack up (yet) or b) has further potential.
