Whoo Hooo GBG made $US1.50 per tonne margin on sales during June quarter!
Costs were up $US5 per tonne. Otherwise they would have made $US6.50 per tonne.
But wait there's more, the selling price excludes:
"depreciation and amortisation, corporate administration, sale, royalties, ocean freight, interest and financing costs
I would guess $US20 per tonne for all this lot.
