Bougainvilleans living around the huge Panguna mine site remain strongly opposed to a resumption of large scale mining.
And the Pangunans remain bitter about the role of the Australian multi national Rio Tinto in the civil war in the autonomous Papua New Guinea province.
These are among the findings in a report called Voices of Bougainville, a record of the views of villagers around the mine, compiled by Jubilee Australia.
The Panguna mine, run by a subsidiary of Rio Tinto, Bougainville Copper Ltd, was shut down by the landowners in 1989.
The chief executive of Jubilee Australia, Brynnie Goodwill, says people remain stressed and traumatised because of the subsequent civil war and these issues must be addressed.
"I think that what has been loudly said by the Pangunan communities is that other opportunities need to be explored that are alternatives to mining, or potentially other ways of doing mining - smaller scale mining. All these issues are the concerns of people that have not been investigated."
That is the chief executive of the NGO, Jubilee Australia, Brynnie Goodwill.
