As said - it was just a slide with costs for Aussie producers. Most other companies had considerably lower costs.
At todays $130 extra 20% makes $156. Makes about $50/t profit.
Dont forget GBG only get 50% of profit. Probably 48% now and still have somewhere in the vicinity of 1 billion in debt. Certainly going to chew into any profit.
