Base Case

If you model the cashflow, using 8% hurdle from 8 years of production, using $1350 as the cost per oz and;

$2350 gold price for the first 135koz, then
$2650 for the next 45koz, then
$2600 for the remaining 6 years

years 1,2 and 8 contributing 90koz
years 3,4,5,6,7 contributing 130koz (40koz a year from Blue Spec)

take $100m off the total 788m profit for debt repay (yes, i know i havent modeled all this exactly, but it suffices the exercise), you get $688m over ~410m shares, which is 1.68 per share.

This base case assumes successful turn on, ongoing prod targets hit and no lithium or exploration success.
Pretty decent return on where we are today! Cant wait.

(oh, and it doesnt allow for tax!)
