Supporting the Argyle Diamond Mine Closure

The Argyle Diamond Mine was once one of the largest producers of diamonds and supplier of natural coloured diamonds in the world, producing more than 865 million carats of rough diamonds since 1985.

Located in the East Kimberley region of Western Australia, the mine has now come to the end of its life, with operator Rio Tinto ceasing operations on 3 November 2020.

Extensive closure planning has been undertaken and closure execution is currently in progress. Cardno, now Stantec (Cardno) is proud to play a key role in this iconic closure project.

Working with Rio Tinto as an integrated team, Cardno has helped support the advanced phases of closure planning, providing environmental engineering expertise to develop technical assessments and designs required for the Mine Closure Plan and Feasibility Study. These assessments ensure closure will be in line with regulatory requirements as well as supporting post-closure outcomes.

Cardno's key specialists David James, Riccardo Divita and James Rayner and the wider Mine Closure team will continue to support the closure of Rio Tinto’s Argyle Diamond mine during the project execution phase following successful completion of closure planning.

As part of the mines closure execution phase, we are supporting the remediation of the site to achieve post-closure outcomes, environmental monitoring, hazardous materials and waste management.

This important and considered phase will ensure the legacy of the mine is one which is positive and provides benefits for the Traditional Owners and custodians of the Country through a re-established natural ecosystem which will support the post-closure land uses identified via consultations with Traditional Owners.

Cardno wishes to acknowledge the Miriwoong, Gija, Malgnin and Woolah people, the Traditional Owners of the land which the Argyle Diamond Mine sits upon.
