Attaining broad-based economic and social developments associated with mining activities are complex to achieve since mining companies take ownership of social responsibility while all layers of government become complacent and social inclusion entices direct involvement of landowners in decisionmaking. To reduce community boycott and social crisis, mining companies and the Government of Papua New Guinea (GoPNG) adopted a preferential mode of social inclusion to redistribute the benefit streams associated with a mining operation. However, the preferential treatment of landowner communities inhibits achieving the social sustainability goals. There is no clear framework within which the social preferential mode of benefit redistribution could work in mobilizing the cultural and land-based endowments. In recognising the issue, employing a bottom-up approach to planning of physical infrastructure and social institutions and integrating them into government's existing service delivery mechanisms could achieve broad-based sustainable livelihoods in the post-mine era. The qualitative data were collected from interviews of selected stakeholders from the Tipini and Porgera special mining lease (SML) communities to predict the scenarios that could emerge in the post-mine period. The strategies discussed could guide the stakeholders to achieve social sustainability to occur during the remaining life of the Porgera mine.
