Fortescue Metals Group has put proposed port facilities at South West Creek in Port Hedland front and centre as its main interest in Atlas Iron. The Andrew Forrest-controlled company has called on Atlas to clarify what rights it holds to develop the so-called Stanley Point Berths 3 and 4, opposite Fortescue's existing port facilities. "In common with other Atlas shareholders, Fortescue believes that further clarity is needed on the position of Atlas in relation to these assets and we continue to assess our strategic options regarding our shareholding in Atlas," the iron ore miner said in a statement this afternoon. Atlas was thought to hold a priority right to develop South West Creek via its 63 per cent holding in the North West Infrastructure joint venture with Brockman Mining.
