Based on 8Mtpa if KML had a pellet plant and we received $US50 extra KML would make $400m in revenue, but unsure of the cost.
We know that GRR sold 2.37m of magnetite pellets at $AUD149.76 per tonne with a C1 cost of $AUD98.10 per tonne.
After tax profit of $AUD112.9m on 2.37m tonnes or $47.64 per tonne.
