Following last month’s tailings dam disaster at Vale’s (NYSE: VALE) Córrego do Feijão mining complex, which left at least 140 dead, Amsterdam-based Responsible Mining Foundation issued a statement highlighting the findings of its 2018 Responsible Mining Index report related to miners’ tailing dams.
According to the report, many of the world’s largest mining companies are not able to ‘know and show’ how effectively they are addressing the risks of tailings dam failure and seepage.
“The 30 mining companies assessed in RMI 2018 scored an average of only 22% on tracking, reviewing and acting to improve their tailings risk management, with Vale scoring slightly above average. Fifteen of the 30 companies showed no evidence of keeping track of how effectively they are addressing these risks.
And while 17 companies showed some sign of reviewing the effectiveness of their tailings risk management measures, no evidence was found of any of these companies publicly disclosing the extent to which they have taken systematic action on the basis of these reviews, to improve how they address tailings-related risks,” the document reads.
The RMF states that the deficiencies many miners show when it comes to sharing information is not limited to their tailings dams.
