SnapshotThe last day of mining at Argyle was 3 November 2020. This marked the beginning of the transition to the lengthy and detailed closure process. Argyle has a mine closure plan, that outlines approach to decommission the mine, reshape and rehabilitate the land, preserve ecological and cultural heritage values, support future land uses by Traditional Owners and ensure a smooth transition for the local community.

Rio Tinto expect it will take 3 to 5 years to dismantle the operational infrastructure, reshape the land and undertake revegetation activities to enable the re-establishment of a natural ecosystem.

In 2023, completed removal of the processing plant above ground infrastructure, continued reprofiling of the alluvial mining and waste rock landforms and capping of the tailings storage facility.
