SYDNEY--Rio Tinto PLC (RIO.LN) said it will spend US$146 million on initial work for its planned Koodaideri iron ore mine in Western Australia ahead of a final decision on the project later this year.

The mining company said the cash would be used for detailed engineering work, development of a rail construction camp and the first stage of a workers' camp for the mine.

Construction on the project, if approved by directors, will start in 2019. The mine would be operational in 2021.
