Good points Orewealth. Any trend in the AUS dollar back towards parity (or lower) while still maintaining higher ore prices (the 'ol stagflation chestnut) would put the NPV to the sky! Excellent point on the additional tonnage too - in the past the market has been ambivalent about tonnage upgrades, but your post makes it pretty clear that even 19mil tonnes is over a (potentially) year more of production = 1.5billion+ in pre-cost and pre-tax cash at 100/tonne price guess.
Also good link highlighting the media attention IOH is starting to get again. Still a lot of hurdles to overcome but I think the company will be seen as a must have before the end of the year... :)
