ICMM releases updated tailings management and mine closure guidance

The International Council on Mining and Metals (ICMM) announced Wednesday it has published new editions of resources with updates designed to improve how mining companies plan and manage the closure of tailings storage facilities.

The closure of tailings storage facilities is one of the most complex 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.

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

ICMM said its approach emphasizes 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,” ICMM managing director Emma Gagen said in a news release.

Gagen said 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.

The updates support companies in developing criteria for the closure of a tailings storage facility, setting clearer governance structures during closure and post-closure stages and improving integration of closure considerations into tailings storage facility design and operation.
