Ann: Pilbara Board Approves Ngungaju Plant Restart, page-51

I think the market is a bit concerned about the increase in unit cash costs but a fair bit of that is shipping costs and they have flagged costs will drop.
"costs are expected to trend lower with the realisation of expected synergies and improved economies of scale from the combined operations following the ramp up of the Ngungaju Operation, as well as strip ratios and freight costs returning to more normal levels".

I also think the market may be confused about the 2021/22 production forecast of 560,000-580,000 dmt pa as this appears lower than the 680,000 dmt Pa that was quoted in a previous presentation.
The 580,000dmt however clearly states that its Pilgan plant stage 1 improvements plus Ngungaju and doesn't include Pilgan stage 2 expansion (phase1) (which was the 680,000 dmt).

So in summary its all good.....
