 · If open pit mining continued to include pushback 14 this would destroy total value since the cost of accessing pushback 14 exceeds the revenue that would be obtained from processing and selling the copper contained within its ore. The undiscounted breakeven pit limit will therefore occur at pushback 13 for the truck haulage scenario. After taking into account the total CAPEX requirement of ...
