Sky News Business Editor Edward Boyd has travelled to Rio Tinto’s GudaiDarri mine in Western Australia to see the mining corporation's newest and most technologically advanced mine.

This is the first largescale media trip Rio Tinto has hosted since the Juukan Gorge scandal – which saw 46,000yearold aboriginal shelters blown up by the company.

The $3.1 billion GudaiDarri mine began its production in 2021 and reached its capacity of 43 million tonnes in less than four months.

Rio Tinto plans to invest a further $130 million – expanding the mine's output to 50 million tonnes.

GudaiDarri uses autonomous trucks, drills, water carts and trains – as well as remote control robots that inspect conveyor belts for bearing failures and damage.

The driverless trucks only stop to be refuelled or serviced.
