The governor of Madang, Peter Yama, says a slurry spillage from the Ramu nickel mine is the worst environmental disaster in Papua New Guinea.
This came after a spill into a creek turned the sea red which is a threat to marine life as well as local villagers.
The Post Courier reported Mr Yama has called on the government to immediately close down the Chinese government-owned and operated Ramu nickel project because of its poor environmental record.
