Haulage costsThe term haulage cost of ore blocks can be divided into two separate parts. The first part includes the trucking cost from the block to the primary crusher and the second part is the conveying cost of the block from the primary crusher to the secondary crusher or processing plant. For waste materials, the haulage cost just includes the trucking cost. It is worth noting that, in this research, the conveying cost from the primary crusher to the secondary crusher is considered a part of mining cost not processing cost. Equation SM.1 shows how one can calculate the haulage cost (HCbj ) to any destination. bj bj j HC THC CHC  (SM.1)Where THCbj is the trucking cost of material ($/tonne) from block b to destination j and CHCj is the conveying cost ($/tonne) from destination j to the secondary crusher. For waste blocks, the term CHC is equal to zero. The truck operating cost can be calculated by using Equation SM.2.
