Inside Rio Tinto’s most advanced mine

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

This is the first large-scale media trip Rio Tinto has hosted since the Juukan Gorge scandal – which saw 46,000-year-old aboriginal shelters blown up by the company.

The $3.1 billion Gudai-Darri 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.

Gudai-Darri 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.
