ICMM releases updated guidance to strengthen approaches to the closure of tailings storage facilities

The closure of tailings storage facilities is one of the most complex, longest and resource-intensive phases within a mine’s lifecycle.

ICMM has published new editions of key resources, with updates designed to improve how mining companies plan and manage the closure of tailings storage facilities.

The Tailings Management Good Practice Guide (2nd edition) and Integrated Mine Closure Good Practice Guide (3rd edition) introduce enhanced strategies for integrating tailings management and mine closure processes. These updates reflect the latest industry knowledge and guide companies to strengthen the governance and long-term stability of closed facilities.

 Closure of tailings 

The closure of tailings storage facilities is one of the most complex, longest and resource-intensive phases within a mine’s lifecycle. It requires extensive environmental assessments, long-term monitoring, rehabilitation and maintenance strategies to manage safety, environmental and social risks. ICMM’s approach emphasises early planning, strong governance and progressive closure activities to support delivery of positive outcomes for both ecosystems and local communities.

Closure is a critical phase of every mining or metals processing operation and presents an opportunity to strengthen environmental, social and economic resilience far beyond the mine’s life cycle. Achieving these positive outcomes hinges on early planning and progressive closure approaches – especially for tailings storage facilities, where risks can extend long after operations cease.

“ICMM’s updated tailings management and integrated mine closure guidance will help companies to continually learn and improve, raising the bar on safety and environmental stewardship across the sector for decades to come." The Dr Emma Gagen, Director, ICMM, stated. 

The updates support companies in the following areas:

• Developing meaningful success criteria for the closure of a tailings storage facility
• Setting clearer governance structures during closure and post-closure stages
• Improving integration of closure considerations into tailings storage facility design and operation
