17.1 13.7 14.9 12.0 PERFORMANCE AND TARGETS Petra’s ore tonnage throughput increased by 9% to 14.9 Mt. ROM tonnes treated increased 10% to 13.3 Mt driven by an 11% increase in underground ROM tonnes mined from the South African operations and a 9% increase in tonnages mined from the Williamson open pit of 5.1 Mt whilst the contribution from surface overburden ROM material at Finsch remained flat at 0.6 Mt. RISK MANAGEMENT Realistic operational targets, based on detailed mine production planning, with production performance monitored closely.
