Vale informs that it has temporarily and on a preventive basis suspended the operation of the Alegria mine, in the Mariana complex, despite the stability of its structures. Under stress conditions, the results from preliminary analysis of its structures were inconclusive, not being possible to guarantee their stability under such conditions.
 
The studies will continue and, as soon as they are completed with assurance of stability under stress conditions, the operations will be resumed.
 
Vale estimates a maximum potential impact on production of approximately 10 Mtpy.
