The Brazilian Institute of Social and Economic Analyses (IBASE) and the organisation Publish What You Pay launched the report "In Search of Transparency: Ending Opacity in Brazil's Extractive Sector - An action-research case study of the Minas-Rio iron ore mine". The document provides an overview of environmental impacts and human rights violations that are allegedly occurring due to the activities of the Minas-Rio iron ore mine, owned by Anglo American, in Minas Gerais, such as water shortages and physical and mental health problems identified in low-income Afro-descendant communities. These communities also demonstrate a constant fear that a tragedy will occur, since there is a dangerous failure in the mine's tailing dam.

IBASE and PWYP further reveal an alleged lack of transparency and accountability of the federal government regarding tax and royalty revenues from mining. The report provides data about the social costs represented by the mine, which, according to the publication, is not reporting to the communities where this revenue is spent.

The BHRRC invited Anglo American to comment on the report and the company did so.
