AMN's scoping study suggests the all in sustaining cash cost FOB is $370.00
RWD's AISC is $394.
Rwd have carefully detailed their transport including wharfage and handling in Newman. AMN have yet to describe handling at rail head and in Darwin or separated the road element from rail. 3x is probably not reasonable, I accept that. But at $190.00 it is much higher than RWD. ($123)
After deducting transport from both coys, AMN are claiming to be able to deliver potash to the mine gate $179/tonne cheaper. Do you believe that or perhaps AMN have a little more work to do such as water provision for a start.
