  • M&A

    In 2015, Zijin Mining acquired a 50% interest and 50% debt in Barrick (Niugini) Limited(BNL), securing a 50% stake in the Porgera Gold Mine. In April 2020, the mine was put on care and maintenance due to the expiration of its mining license. After negotiations, in October 2023, the project received a special mining lease from the Papua New Guinea government. It resumed production on December 22, 2023. Zijin Mining indirectly holds a 24.5% interest in the mine.


Since its commissioning in 1990, the project has contributed around 10% of Papua New Guinea’s annual exports. Committed to growing together with its host communities and other stakeholders, it pays taxes and royalties to the landowners and the provincial government in accordance with the law, and signs contracts with local companies. Additionally, the project supports local schools, medical facilities, and various public projects, such as water and electricity infrastructure, and roads.
