Ports conference, July 9, 2015.
It's not so much as a cost price, just a graph showing the indexed price. It shows that it's just below the $50 mark.
The abc reported yesterday that Karara is losing about $200 million per year. At 8 million tons per year, the price of IO would need to increase by $25 just to break even.
That's the only thing I've seen in regards to cost price released by gbg.
