I would really have hoped they could go to 4mtpa straight away for the very small investment ($37m) especially if they can improve on 41mt @ 0.86% Cu used in the PFS which I’m sure they can... but it seems we are restricted in expanding until grid power is connected in 2022 (initial diesel generators have just 14MW capacity so probably can only sustain the infrastructure for a 2.5mtpa throughput plant).
