Mining Methods and Equipment

The majority of open pit mines in Australia currently operate using discontinuous shovel/truck systems These systems are favoured as they enable (i) mining capacity to be progressively scaled up over the life of a mine (ii) the use of narrow benches that defer the high costs of stripping and (iii) flexibility to rapidly adapt mine plans in
