I have had a looked through the FS and can see that forecast C3 is US$.50 at full production.
they mentioned that that are already at about the 8mt rate of stage 1. Zinc in concentrate should be approx 140mt/year at current rate. If close to that C3 now then 65 -70 cent/lb margin (zinc at $1.15-1.20lb) is operating profit of A$280 -$300m.
any problems with the above? any ideas out there of current operating cost.
