The contractor/miner has a market capitalisation of more than A$11 billion, up nearly 30% over the past year due to the resilient iron ore price and rising lithium price.
The ASX 200 will gain two more lithium miners.
Developers Lake Resources and Core Lithium will be added to the index, joining fellow lithium companies MinRes, Pilbara Minerals, Allkem, Liontown Resources and AVZ Minerals.
Coal producer New Hope Corporation will also re-join the ASX 200, buoyed by the recent strength in coal prices.
The changes take effect prior to the market opening on June 20.
