Tailings & waste

It is AngloGold Ashanti’s obligation to ensure our mine tailings are stable, non-polluting and contained.

Ensuring that tailings storage facilities are responsibly maintained is crucial to maintaining our licence to operate. Our tailings storage facilities are designed and built to a rigorous set of standards and carefully managed and monitored through a team of internal specialists and independent external experts.

As of 5 August 2020, all ICMM members, which we are, committed to implementing the Global Industry Standard on Tailings Management. This standard, which is available at www.icmm.com, has been welcomed by AngloGold Ashanti.

At our Brazil operations, work is currently underway for accelerated decommissioning of existing TSFs and conversion thereof into dry stack facilities, to meet that country’s requirements.

Following the sale of our South African and Mali operations, AngloGold Ashanti manages 22 tailings facilities, with 15 active TSFs and 7 inactive (dormant).

Global industry standard on tailings management

Strengthening current practices in the mining industry by integrating social, environmental and technical considerations, the Standard covers the entire tailings facility lifecycle – from site selection, design and construction, through management and monitoring, to closure and post-closure.

With the ultimate goal of zero harm to people and the environment, the Standard sets a global benchmark for achieving strong social, environmental and technical outcomes. It elevates accountability to the highest organisational levels and adds new requirements for independent oversight. The Standard also establishes clear expectations around transparency and public disclosure, helping to improve understanding by interested stakeholders.

Comprising six Topic areas, 15 Principles and 77 auditable Requirements, the Standard provides a framework for safe tailings facility management while affording Operators flexibility as to how best to achieve this goal.
