The South Deep gold mine achieved several milestones in 2016 as interventions implemented over the past two years started yielding results and dual-listed Gold Fields will now embark on a new R2.3-billion rebase plan at the mine to create a defensive asset in a spiralling industry. Equipped with a new long-term build-up plan for the underperforming South Deep, the next five years will see the ramp-up to steady-state production of 500 000 oz/y at an all-in costs (AIC) of below $900/oz, with a 70-year lifespan.
