SnapshotThe operational area of the Martabe mine includes three open pit mines, Ramba Joring Pit, Barani Pit, and Purnama Pit, and a conventional carbon-in-leach gold ore processing plant and utilizes a ReCyn Plant for cyanide recovery and detoxification, ensuring environmental compliance.

Martabe Phase 2 involves ongoing resource exploration, studies on sulphide minerals, assessments of underground mining potential, and the construction of new tailings management facilities.

In 2024, a significant milestone of the Martabe Phase 2 project was achieved with the successful completion of the Filtration Plant.

Agincourt has reportedly suspended operations at the Martabe gold mine effective December 6, 2025.

On January 20, 2026, the Forest Area Regulation Task Force revoked the Martabe gold mining business permit, belonging to Agincourt. Agincourt, along with five other non-forestry companies, has been accused of causing forest damage that led to flooding in North Sumatra in 2025.
