Bougainville Copper Limited is a publicly listed mineral exploration and development company headquartered in Port Moresby, Papua New Guinea. Its primary function is to advance exploration activities and redevelop the Panguna mine, historically recognized as one of the world's largest copper deposits. The company holds extensive mining leases and exploration licenses on Bougainville Island, with strategic interests in copper, gold, and silver resources. After the cessation of mining operations in 1989 and the departure of Rio Tinto in 2016, Bougainville Copper has focused on building strong local governance and stakeholder relations, resulting in significant shareholding by both the Autonomous Bougainville Government and the Government of Papua New Guinea. The company emphasizes sustainable mining practices and economic self-reliance for Bougainville, positioning itself as a key driver in the region’s development and in the broader materials sector, with a dedicated local management team and a commitment to constructive community engagement.
