Vale corrected report and did not “tamper” with it, as reported by the press

6/7/2016 11:00 AM

Vale corrected data provided in their Mining Report (RALs) on production at the Alegria Mine, part of whose tailings were deposited in the Fundão dam owned by Samarco. The initiative took place due to disagreements about the technical criteria adopted in some of the 3000 fields in the document. Contrary to what has been published in newspaper reports, the company did not tamper with any information.

Last year on 18 December an alignment meeting about the reports took place between Vale and the National Department of Mineral Production (DNPM). At this meeting it was found that Vale had used different criteria to that of the agency when filling out the RALs documents relating to the 2010 to 2014 tax years. As a result of this alignment meeting Vale corrected information on 50 of the more than 3,400 fields in the document, this corresponds to less than 1% of the information contained in it. The new information was sent to the DNPM via the electronic RALWeb system on 22 December 2015. The system acknowledged receipt of the corrections.

The data corrected was in relation to liquid effluents which had previously been calculated by taking into account the sandy waste and mud with the effect of recirculation. After the hearing it was understood that the volume of water should be calculated without taking into account the effect of recirculation. The unit of measurement was also changed from tons to cubic meters. Vale's lawyer David Rechulski points out, however, that there was no change in information related to the concentration of iron ore in the dam. "An important fact is that the concentration of iron ore in the Alegria dam was kept unchanged ", he stressed.

Vale's actions clearly demonstrate the company's intention of acting in a clear and transparent manner. As the supervisory body was aware of the changes to the data and its causes the rectification cannot be classified as tampering as reported in the press.
