I got the figures from listening to Jospeth Gutnick. He gave transport costs in Australian dollars wich I loosely translated to US$. He seemed to suggest that initially they would transport rock by road to the port and in time would use the rail ooption. I didn't get use of both from what he said, but perhaps I misunderstood him. He was very clear on the current price of Phosphate though and his figures are a long way from yours.

The main thing is that they are profitable even at this low price and are sitting on an unbelievable 1 billion tons of the stuff.
