Mid-tier iron ore miner, Atlas Iron says it is in discussions with BHP Billiton about gaining access to its rail network in Western Australia's Pilbara region.
The two miners are discussing the possibility of the using BHP's Goldsworthy line to and from the junction of the company's Newman line.
The move may be a positive development for other junior iron ore miners who have been seeking access to BHP's infrastructure in the region.
Last month BHP and its rival Rio Tinto called off a $120 billion plan to merge their iron ore operations in the Pilbara.
The miners had hoped the move would achieve significant cost savings.
But regulatory opposition from a number of countries, most notably the members of the European Union, crippled the deal.
