Straight From The Horses Mouth, page-6

Includes usual talk of advantages. Mentions railhead when DFS clearly outlines trucking option. I am yet to see any WA SOP company with potential access to rail (AMN, SO4, APC) make a serious case for rail yet they all, at some stage, have talked it up. They are all, without exception, planning on 800km plus road trips.
Good presentation with usual caveat that all of these CEO's push the message that suits their agenda and the limitations as well as the advantages that their respective projects have.
Sounds like things are coming together.
