Study finds that one in ten Brazilian mines could be abandoned

According to a study conducted by the think tank Instituto Escolhas in Brazil, there are 3,943 abandoned mining sites, which represents 11% of all authorized operations. This highlights social and environmental risks posed when miners ignore regulations.

The study, based on data provided by the National Mining Agency, points out threats like deforested land that has not been restored, soil and water contamination, and physical instability caused by abandoned mines.

The study cites an internal ANM document that acknowledges ANM's lack data and oversight over areas where mine operators should be restoring.

The ANM document, dated November 20,24, signed by the leader of the task force for updating regulations, stated that "there is a total lack of control" over the number and size of abandoned mines.

The ANM has not responded to a comment request.

The Brazilian Mining Association IBRAM declined to comment until it had reviewed the study.

Brazil is the world's largest producer of iron ore. It also mines nickel and gold.

Instituto Escolhas has noted that Brazilian law holds companies responsible for restoring the areas damaged by mining activities. The study did, however, highlight gaps in enforcement including the lack of ANM Inspectors.

Larissa Rodrigues is the director of research at the Institute. She believes that miners must provide guarantees to their financial ability to restore an area before they are granted a permit.

The study did not include the names of the companies. Reporting by Ricardo Brito, Brasilia; writing by Marcela Ayres and Rod Nickel; editing by Brad Haynes and Rod Nickel
