That the China Railway group has the ability to take 15 % equity stake is another brick in the wall.

Perspective.

At Roy Hill the US Ex-Im Bank supplied $ 700 m finance out of $ 10 b project ---- this = 7 % so that Caterpillar equipment is used.
For IRD CEIP China Railway will put in $ 4 bn x 15 % = $ 600m
This 15 % exceeds cost of railway to Port Hardy 144 km x $ 3m per km = $ 432m
IMHO this is a bigger vote of confidence and the normal business conduit.

A consortium of like minded investors should galvanised this project into commencement.
