Case Study: Copper‑gold miner achieves 20% NPV uplift and a shorter life-of-mine with RPMGlobal SOT

Copper-gold miner boosts strategic planning value and maximises productivity with SOT

Copper-Gold Miner faced the challenge of maximising the net present value (NPV) of an open pit operation with two processing plants and complex ore-type and slope constraints; their existing software identified high-margin areas but failed to deliver an NPV-optimised long-term schedule. They engaged RPMGlobal to apply its SOT strategic optimisation tool (with integration to RPMGlobal’s OPMS) to overcome the combinatorial scheduling complexity and improve planning outcomes.

RPMGlobal deployed SOT to evaluate over 6,800 schedules across more than 15,000 blocks, producing an optimised plan that increased NPV by 20% while shortening the life of mine and front-loading higher-value material, all while enforcing slope and ore-type constraints. The RPMGlobal solution enabled visualization in OPMS, rapid sensitivity analysis and re-optimisation for changing costs, fleet or metal prices, delivering stronger strategic planning, higher productivity and measurable value uplift.
