Société Le Nickel (SLN) operates five major mining hubs spread across the East and West coasts of New Caledonia. SLN produce high-grade ferronickel from the Doniambo smelter in Noumea. The project requires complex planning and logistics across all mine sites to maintain a consistent and chemically balanced feed to the smelter. However, there are over 300 individual pit phases to schedule and integrate into a single holistic business plan that must also be tactically achievable by production teams at each site. The complexity of the problem is increased by social, environmental and political influences on the timing and sequencing of operations that are often outside the control of the company.
