Fortescue Metals Group is considering the sale of a minority share in its port and rail infrastructure.
The company says there has been investor interest in FMG's wholly-owned subsidiary The Pilbara Infrastructure (TPI), which owns and operates the miner's port and rail assets.
Aside from transporting Fortescue's iron ore production, TPI also provides transport for other miners operating in the area.
Fortescue's chief executive Nev Power says there are a number of companies that have expressed interest in investing in TPI.
"These investors recognise the world class infrastructure assets which Fortescue has developed," he noted in a statement.
"They are also attracted by the fact that TPI is the only provider of third party infrastructure in the Pilbara and the logistics chain is fully operational." Fortescue says discussions around a sale are being conducted with a small group of selected investors.
It says any sale will only occur at what FMG considers a full and fair market value, and will not effect the efficiency of the infrastructure.
Lazard and Macquarie Capital are acting as Fortescue's financial advisers on the potential transaction.
Fortescue shares were up 3.25 per cent to $4.45 by 10:37am (AEDT).
