āTHE MOVE IS JUST A PREVENTIVE MEASURE UNTIL A TECHNICAL ANALYSIS OF THE STRUCTURES IS COMPLETEDā ValeIt did not expect any impact on its 2020 production plan, which has been forecast at between 310 and 330 million tonnes of iron ore. That projection, revised in April, considers as much as 15 million lost tonnes from eventual covid-19 impacts. The announcement is the latest in aĀ series of emergency level protocols being activatedĀ for Vale dams, with the minerās facilities under increased scrutiny since the Brumadinho tailings dam collapse in January 2019, whichĀ killed at least 270 people and caused widespread damage. The mining giant faces legal action over the incident, the deadliest in Brazilās mining history, including allegations that Vale wasĀ aware of the damās unstable conditionĀ years before the accident happened. In January, state prosecutors charged Fabio Schvartsman, the chief executive at the time of the burst, andĀ 15 other peopleĀ with homicide. Schvartsman left his position at the company in March 2019. They also charged Vale and its German contractor, TUV SUD, with environmental crimes, as the burst dam unleashed an avalanche of muddy mining waste that polluted the nearby town of Brumadinho, water streams, and agricultural land.
Mounting pressure
In May, a Brazilian judge ordered the company to set aside 7.9 billion reais (about $1.5 billion)Ā to pay potential fines relatedĀ to last yearās disaster. The figure added to the 1 billion reaisĀ ($260m at the time) in frozen fundsĀ a federal court ordered Vale to pay affected communitiesĀ shortly after the deadly incident.
Tailings in the spotlight
The tragic 2019 incident has triggered over the past year several criminal investigations,Ā including aĀ global inquiry into the status of 726 tailing dams. It has also put the safety of those structures under the microscope.
The International Council on Mining and MetalsĀ (ICMM), a London-based industry group representing 27 major mining companies, formedĀ an independent panel of expertsĀ in charge of developing global standards for tailings facilities.
The Church of England, which invests in mining companies through its pensions for retired clergy, along with its partners,Ā launched a global inquiryĀ in April 2019 into the mining waste storage systems of more than 700 resources companies.

It now asks companies to disclose data on tailings dams on a regular basis.
Switzerland-basedĀ Responsible Mining FoundationĀ (RMF)Ā published a study in early AprilĀ this year, showing that investor-led action had resulted in improved transparency regarding the state of such facilities.
The vast majority of miners, however, have yet to demonstrate they are reviewing how they effectively manage tailings-related risks.
The non-profit, funded by the Dutch and Swiss governments and some small philanthropic organizations, saidĀ that while a global standard on tailings management is a welcome initiative, it could be strengthened to become significant in terms of tailings safety.
