Translation 12:12:24PM May 27, 2019 Source:SMM

SMM5, 27 March: recently, Vale announced that the northern slope of the Soco mine in the Congo is moving at a rate of 15.5cm (6.1in) a day, which has been paralyzed since 2016. Some of the remote locations of the idle mine even move 20 centimeters a day. With a daily displacement speed of more than 10 centimeters per year since 2012, the slope is at risk of collapse at any time. Vale is currently assessing the potential impact of vibration caused by this displacement on the Sul Superior dam, about 1.5km from the slope.

It is reported that the, Sul Superior dam was classified as level 3 on March 22 and that a preventive evacuation was carried out in the self-rescue area (ZAS,Zona de Autossalvamento) on February 8. All preventive measures have been taken in response to this situation including emergency training with residents of secondary school safety zones. Also in March, Civil Defence and Vale equipped ZSS with escape route signs. It is reported that according to the definition of the emergency mining dam response plan, the self-rescue area is 10 kilometers or 30 minutes from the dam rupture point.
