BCL has overseen the successful demolition and removal of three unsafe masonry walls that were identified as imminent severe risks through the Panguna Mine Legacy Impact Assessment (PMLIA) process.
These structures were assessed as posing a threat to public safety, and their removal represents an important step in reducing hazards within the former Panguna mine area.
Commitment to Addressing Legacy Impacts
BCL, the Autonomous Bougainville Government (ABG), and Rio Tinto have acknowledged the findings of the PMLIA and remain committed to addressing legacy impacts in a responsible, transparent, and collaborative manner. The removal of these walls forms part of BCL’s broader commitment to oversee remedial works associated with the most urgent risks identified through the PMLIA.
In 2025, the parties established a roundtable forum as a platform for coordination and engagement with Bougainvillean community leaders. Its immediate role is addressing high to very high risks from the PMLIA report. The demolition of the walls demonstrates early action and progress in addressing identified hazards.
Ongoing Planned Works to Address Remaining ISRs
Further planned works are also underway to address remaining sites identified during PMLIA fieldwork including the removal of hazardous chemicals from Loloho Port, addressing flooding at Kuneka Creek, and the demolition of other unsafe structures in the mine area. These activities are being progressively advanced, with safety and stakeholder engagement guiding all works.
Looking Ahead
BCL recognises the importance of addressing historical impacts as part of the broader pathway toward responsible management of the Panguna mine legacy. The company remains committed to working through established processes to ensure that risks are managed appropriately with public safety prioritised. BCL will continue to provide updates as works progress.
