Just a scenario of reverse engineering the AGO monthly chart from a die hard chartist perspective.
The full long term Monthly Chart of price and volume is the best I have seen in while, with nice long term resistance at 64c.
The volume is the driver to the 64c target.

This equates to about $7.68Bill mcap, so the only way that can happen is if IO increases and more production. So the chart is forecasting a production of 20mtpa with Mcphee creek.  
\Reversing. Assume p/e of 5 for no tax calculations, shares is 12billion as not all options get converted. mcap is 6.78bill. then earnings/share is 64/5=12.8c. and total earnings is  12bill*12.8c=1.536Bill
1536mill/20mtpa=$76.8mill per mtpa or 76.8 margin a tonne.
if costs are 55, then IO price in A$ is 131.
this can happen if IO price is $US100 and ex rate is 70c.

So going forwards to check. 20mtpa at 76.8 margin from costs 55 and sales 131, is 1.536 bill $ income.
p/e of 5 is 7.68 bill mcap on 12bill shares. is price of 7.68/12 =64c.

This means the Monthly chart approves of the development of McPhee Creek.
