US$73m of improvement ideas implemented through operational improvement for an open-cut gold mine

Business challenge

Our client needed to improve productivity and overall operations while factoring in tough mining conditions, high turnover of the management team, and high operational downtime.

Context

An open-pit gold miner had just completed a transition to owner-mining, and faced many operational challenges including old mining equipment and a high-maintenance processing plant.

Unit costs were under severe pressure: fixed costs increased by 100% following the transition; rising fuel and power costs; main pit getting deeper and haul distances longer.
