Member Disclosures on Progress Towards Conformance with the Global Industry Standard on Tailings Management

5 August 2025

When it was published in August 2020, ICMM members committed to conform with the Global Industry Standard on Tailings Management for all tailings facilities classified as ‘extreme’ or ‘very high’ consequences by August 2023, and all other facilities by August 2025.

This commitment galvanised immediate and sustained action by ICMM members, representing one third of the global mining industry. We are pleased to share the progress that companies have made so far.

We are developing a Tailings Progress Report which we will publish in Q4 providing our analysis of collective member conformance. In the meantime, you can view members' individual disclosures towards their progress towards conformance with the GISTM for all of their applicable tailings facilities using the links below.
