Talison Lithium will lead a study into reopening the Greenbushes rail line in a move that would take trucks off the South West Highway but may create new disruption for motorists.
A big expansion of lithium production at the Greenbushes mine is a step closer after Talison Lithium was given environmental approval for its plans to lift output to 2.8 million tonnes per annum.
An $800 million expansion of Talison Lithium's Greenbushes site will go ahead after Talison and Global Advanced Metals resolved a legal dispute over the plans.
Talison Lithium has confirmed it will build a third concentrator at the Greenbushes lithium mine to boost output to 1.95 million tonnes per annum, but the owner of tantalum rights at the project has again warned the expansion will be subject to an ongoing legal battle.
