Where you’ll be working

The Argyle diamond mine is located on the traditional country of the Miriwoong, Gija, Malgnin and Wularr people in Western Australia. We acknowledge the Dawang / Daam groups who are the Traditional Owners of the Barramundi Dreaming – the Tiltuwam, Mandangala, Yunurr / Yalangga, Neminuwarlin, Balaburr, Bilbildjing and Upper Jimbila people.

Argyle was one of the world’s largest producers of diamonds and the largest supplier of natural coloured diamonds – including white, yellow, brown, blue, violet and the rare and the highly-coveted Argyle pink and red diamonds.

Mining ceased at Argyle in November 2020, after 37 years of operation. 

We are committed to respectfully closing and rehabilitating the mine and returning the land to its traditional custodians.

Applications close on 18th of September 2026 (Rio Tinto reserves the right to remove advertised roles prior to this date).
