Panguna Copper Mine Moves Closer to Potential Redevelopment as Lloyds Metals Receives Preparatory Works Approval

According to foreign media reports, Lloyds Metals & Energy has been authorized to undertake preparatory works and feasibility activities aimed at assessing the potential redevelopment of the Panguna copper-gold mine in Bougainville, Papua New Guinea, nearly four decades after the operation was shut down.

The Autonomous Bougainville Government granted the authorization on August 7, allowing Lloyds to carry out an approved programme of preparatory and feasibility work required to assess and plan the future redevelopment of the mine. Lloyds is acting as the approved development partner of government-owned Bougainville Minerals, which holds the mining lease covering Panguna.

The project represents a potentially significant source of long-term copper supply. Panguna's remaining reserves are estimated at approximately 5.3 million tonnes of copper and 19.3 million oz of gold, while Lloyds plans to revalidate the project's resource base as part of the redevelopment process. The mine has remained closed since 1989.

The latest authorization follows the granting of a 25-year mining lease to Bougainville Minerals in June, providing a framework for further evaluation of the dormant asset. However, the current approval does not permit construction or copper production to begin. Any progression into those stages will require additional approvals, meaning a potential restart remains subject to further technical, regulatory and development work.

The renewed progress at Panguna is notable given the scale of the historical deposit and growing efforts globally to develop additional copper supply. The immediate impact on mine supply remains limited, but successful feasibility work and resource revalidation could provide greater clarity on whether one of the world's largest dormant copper assets can eventually return to production.
