Numa Numa Resources Inc., a mining and infrastructure development company headquartered in the Autonomous Region of Bougainville, is positioning itself to revive the historic Panguna Mine with a modern approach centered on cooperation, community engagement, and responsible governance. The Panguna Mine, once among the world’s largest copper and gold mines, generated substantial export revenue for Papua New Guinea before disputes over environmental impacts, land ownership, and benefit distribution contributed to the decade-long Bougainville conflict, known as “the Crisis.” Now, as Bougainville undergoes political and economic evolution, Numa Numa Resources aims to transform the mine’s legacy from conflict into a model for sustainable development and regional stability.
Developed by Rio Tinto, the Panguna Mine operated from 1972 to 1989 as the largest open-cut copper and gold mine globally. It was shuttered due to the civil war between Bougainville and its parent government, Papua New Guinea. The 2001 Bougainville Peace Agreement ended the war and granted Bougainville limited autonomy, including its own constitution, under which ownership of the mine reverted to its customary landowners. A majority of the Panguna Mine’s copper, gold, and silver ore resources remain within its walls, making it one of the largest ore bodies in the world, today worth approximately $100 billion. Most geologists who have studied Bougainville believe that other nearby locations, such as Mainoki and Karato, are highly prospective and may contain ore deposits similar in size and scale to those of the Panguna Mine.
Numa Numa Resources is working to build partnerships with customary landowners and local stakeholders while aligning with Bougainville’s legal framework, emphasizing consultation, consent, and shared long-term benefits. The company’s management has lived and worked in Bougainville for 10 years, underscoring its commitment to the region. As modern mining projects increasingly adopt more inclusive, environmentally conscious, and community-centered approaches, Numa Numa Resources aims to help set a new standard for responsible resource development.
The implications of this announcement are significant for Bougainville’s economy and the broader mining industry. Successfully reopening the Panguna Mine could provide substantial economic benefits to the region, including jobs, infrastructure development, and revenue sharing with local communities. It could also serve as a precedent for how large-scale mining projects can be developed in post-conflict regions, balancing economic growth with social and environmental responsibility. For industry leaders, the project highlights the growing importance of community engagement and governance alignment in securing social license to operate.
