This website links to the ICMM Member Companies and their disclosures related to a Church of England request. From the page: The Church of England Pensions Board and the Council on Ethics of the Swedish National Pension Funds wrote to 683 extractive companies, including ICMMÂ’s company members, asking them to disclose details of their tailings storage facilities. ICMM is supportive of greater transparency on this important issue. Members have responded to this request and have published details of the tailings storage facilities that they own or operate on their websites. Links are provided for each participating company, where site- and company-specific information can be found
Tailings production is inherent to mining and metals processing and will remain so for the foreseeable future. ICMM believes that the application of appropriate design and management standards and practices can make tailings facilities safe. ICMM members commit to the prevention of catastrophic failures of tailings facilities and to the continual improvement in the design, construction and operation of tailings facilities.
