Over the past several years, a number of reports claimed that…illnesses suffered by villagers in the area were the result of PT Newmont Minahasa Raya…releasing their mining tailings into Buyat Bay. But a new study…found that no contamination threatening to human health or the environment was found in the bay…Environmental activists, however, are wary of the study’s claims… David Sompie, site manager for Newmont, said the latest research had been entirely independent and the miner was providing $30 million over the next ten years to continue to monitor the impact of the tailings.
