The Porgera Gold Mine ranks among the world’s ten largest gold mines and is the second-largest gold operation in Papua New Guinea.

Production at Porgera resumed in December 2023. Under BNL’s updated plan, the operation is projected to achieve an average annual gold output of 21 tonnes. In 2025, Zijin Mining’s attributable gold production was approximately 2.75 tonnes.

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 mine received a special mining lease from the Papua New Guinea government. It resumed production on December 22, 2023. Zijin Mining now indirectly holds a 20.83% interest in the mine.
