US SEC opens preliminary probe of Vale over dam tragedy

The US Securities and Exchange Commission has opened a preliminary investigation of iron ore miner Vale over the collapse of a Brazilian mining waste dam that killed more than 250 people in January, Brazil’s O Globo newspaper reported on Tuesday.

The US regulator decided to proceed with the probe of the Brazilian company last week after a meeting with Brazilian prosecutors and the CVM, the country’s own market watchdog, the paper reported, without citing sources.
