Glencore auditing 140 slimes dams – by Martin Creamer ( – February 20, 2019)

JOHANNESBURG ( – Diversified mining and marketing company Glencore is auditing 140 slimes dams, 65 of them active and 75 of them closed.

The company has been undertaking detailed assessments and audits of all material tailings storage facilities (TSFs) over the past three years, after accumulating a TSF significant asset footprint through mergers and acquisitions and organic growth.

Glencore CEO Ivan Glasenberg made these revelations at a media briefing on Wednesday against the background of last month’s tragic loss of 170 people at Vale’s Córrego do Feijão iron-ore mine in Brazil, which has prompted renewed industry action to ensure that TSFs are not vulnerable to collapse.

“This is an issue for the mining industry and we support a TSF classification system and requirements for external review, with transparent disclosure to stakeholders and communities,” he told Mining Weekly Online.

Its own internal team to review all its tailings dams in 2014 and a year later, following the death of 19 people in the Vale-BHP Samarco incident in Brazil, independent consultant Klohn Crippen Berger (KCB) of the Canada, was commissioned to review all its dams continually.
