A Guide to the Management of Tailings Facilities (the Tailings Guide) is designed to be applied by MAC members and non-MAC members alike, anywhere in the world. The Tailings Guide provides guidance on responsible tailings management, helps companies develop and implement site-specific tailings management systems, and improves consistency of application of engineering and management principles to tailings management.
In 2021, MAC released its Version 3.2 of the Tailings Guide which can be downloaded here:
For new tailings facilities and for facilities undergoing mine life extensions, the Tailings Guide recommends using a rigorous approach to selection of the most appropriate tailings management technology and facility location. This should be done very early in the life cycle, at the conceptual planning phase of the facility, using the decision-making approach described in Appendix 3 of the Tailings Guide. Further information is available in the following documents:

- A Multiple Accounts Analysis for Tailings Site Selection (Andy Robertson and Shannon Shaw, 1999)
