A report published by Jubilee Australia says people living in villages around Panguna remain stressed and traumatised after years of civil war and are concerned a resumption of mining could lead to more violence.
The Voices of Bougainville report, was published by the Sydney-based non-government organisation in collaboration with partners the International State Crime Initiative and the Bismarck Ramu Group.
Chief executive, Brynnie Goodwill told Radio New Zealand International: "I think that what has been loudly said by the Panguna 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 of these issues are concerns by people that have not been investigated, that the promises of large scale mining, certainly historically, have not been delivered," she said.
"I don't think there's enough knowledge and understanding about what actually this mining operation would involve.
"This is what has been picked up in the report. There is grave concern that it could only lead to more disruption for the community and more violence.
"So I think what the Pangunan communities are saying is that many more issues need to be addressed first and foremost and many more discussions have to be had so that there's not the feeling that is pervading that again the appropriate discussions have not been had about the real issues."
