Bougainville Copper Limited (ASX:BOC) is an independently managed Papua New Guinean mining company focused on the exploration and redevelopment of the Panguna copper-gold-silver mine in central Bougainville; it holds the EL01 exploration licence for the project area, which encompasses one of the world's largest known copper deposits previously producing copper concentrate with significant gold and silver byproducts from an open-pit operation and processing facility until suspension in 1989. The company generates revenue primarily from interest and dividend income while pursuing sustainable mining resumption through advanced pre-feasibility activities, including landowner consultations, social mapping, and technical assessments. Headquartered in Port Moresby with offices in Bougainville, it was founded in 1967 and operates principally in the Autonomous Region of Bougainville, Papua New Guinea, targeting local stakeholders such as landowners, veterans, government entities, women, youth, church groups, and communities.
The Autonomous Bougainville Government (ABG) holds a majority 72.9% stake following the Papua New Guinea government's transfer of its 36.4% share in June 2025, with the remaining 27.1% owned by public and institutional investors; this structure followed Rio Tinto's full exit in 2016. In February 2024, the ABG granted BCL a five-year extension of its EL01 exploration licence, enabling intensified activities under the Bougainville Mining Act 2015 after resolving prior disputes and securing landowner approvals by November 2024. BCL engages Grant Samuel as financial advisor for a strategic partnering process to attract tier-one international mining partners for equity, technical expertise, and redevelopment funding of the multi-billion-dollar project, though no agreements are finalized; recently, the ABG signed a non-binding MOU with Lloyds Metals and Energy Limited for collaboration on Bougainville projects including Panguna, impacting BCL's share price.
