Miner ‘aware of dam issues’

– Brazilian iron-ore miner Vale SA was aware of problems with sensors designed to monitor the structure of a dam two days before it burst, killing an estimated 300 people, Globo TV has reported.

E-mails between Vale executives, auditing firm TÜV SÜD and a third inspection firm discussed discrepancies in data obtained from automated instruments in the dam which appeared not to be working,” the report said. – Reuters
