From the same table in the Jan presso, i have no idea how they calculated their 3.5 year AISC. If you compare it to the H2FY18



Was that a typo??

If we use Nihlism's calculator for both

H2FY18 - (1/(1.4*0.925))*4.5 = 3.47 = AISC ~1350-1400
3.5 year target - (1/(1.5*0.9))*7 = 5.18 = AISC ~ 1550-1600 -

(Apologies corrected figures posted above to calc mined grade not processed, but the point and questions still stand)
