This urgent engagement is being led by the Church of England Pensions Board and Swedish Council on Ethics for the AP Funds and backed by the UN-supported Principles for Responsible Investment (PRI)... As institutional investors in the mining industry and in the absence of common public reporting standards on tailings storage facilities we respectfully request that you provide specific disclosures of all the tailings facilities of your company.

Given the urgency and magnitude of this issue, we request that the public disclosure of this information, certified by either the Chairperson of the Board of Directors and/or the Chief Executive Officer*, be placed on your company website within 45 days of the date of this letter. We are in the process of developing a public investor register of those companies that make the disclosures requested... This disclosure is urgent and essential for investors to be able to understand how your company manages tailings facilities and any associated risks. If you are unable to answer a question, or do not have the requested information, please explain why this is the case and what action the company is taking to address this. We strongly recommend that your disclosure is accompanied by plans to communicate directly with communities that may be affected by your tailings footprint.
