oakajee project faces fresh hurdle, page-11

Padbury's Rail IP should mean they they are the best entity to build the rail - to wherever they need it.
Not only does it provide a link to the port, but excess capacity can be sold to nearby mines.

Of course the company is not in a position today to be building this, but they are not producing today. Be it whitehorse or someoen else, if its going to happen, it would be in the company's best interests to own it, or have significant input into its construction via the IP card.
