Mine Schedule Optimization Shell Selection & Phasing Whittle pit optimization used to determine maximum net discounted cash flow Selection methods incorporate phasing into the ultimate pit shell selection to ensure maximum value – This technique is a departure from what was previously applied at RGM A dilution factor of 8% in soft, 10% in trans and 10% in rock was applied to select the optimized pit shells – Resulted in smaller pit shells due to diminished value of the blocks used to determine the optimized pit shell Apex of Worst case line selected – Practically feasible but least optimized pit shell 45

Mine Schedule Optimization (Contd) Shell Selection & Phasing Apex of best case line selected – Not practically feasible but most optimized pit shell Apex of Phased case – Compromise of optimization and practicality 46
