Fortesue Metals has released the environmental review of its planned Chichester Ranges mining operations and its connecting east-west rail spur for public comment.
The company released the first part of its environmental review, covering its planned port facilities at Anderson Point in Port Hedland and the main north-south rail line from the mine site to the port.
Fortescue said it has already acted on public submissions on the port and rail proposals.
The latest review will end in early March, and Fortescue chief executive Andrew Forrest said the company will act promptly on relevant proposals.
The two environmental reviews are crucial to the prompt completion of the feasibility study and a ministerial go-ahead for the $1.85bn iron ore export project.
