Bougainville Copper is considering re-opening its copper in Papua New Guinea.
The mine was originally forced to close due to civil war on Bougainville Island, which left thousands dead, according to the ABC.
This forced the miner to shut down operations in 1989.
However, land owners have called for the mothballed mine to be re-opened, to provide funds for Bougainville’s independence movement.
Peter Taylor, chairman of Bougainville Copper, welcomed the move by the islanders, adding that the election of a new president last year was a crucial factor in the re-negotiation of the mine’s re-opening.
Initial estimates put the re-commencement of the mine at around $3 billion.
