Papua New Guinea's Acting Prime Minister Sir Moi Avei says Cabinet has voted to shut down the operations of the Ok Tedi Copper mine in 2010.
Sir Moi Avei, whose also the Minister for Petroleum, told stakeholders that the Cabinet's decision was made after Ok Tedi failed to come up with practical solutions to its environment management plan.
The Post Courier reports the government's decision to shut down the mine that contributed 25-percent to the national economy was not an easy one.
He said the Government was now speeding up the process of getting the PNG to Queensland gas pipeline project off the ground before Ok Tedi shuts down.
Sir Moi pointed out that the revenue that the Queensland to PNG gas project will bring into the country will be more than the Ok Tedi mine.
Pollution of the environment by the mine has been a major issue for environmental campaigners, landowners and the Fly River Provincial Government.
