Wetar Copper Mine is the only mine in Indonesia that directly produces copper cathodes. The mine is operated by PT Batutua Kharisma Permai (BKP), the holder of the mining business license, and PT Batutua Tembaga Raya (BTR), which holds the industrial business license to process ore into copper cathodes. Both companies operate on Wetar Island, Southwest Maluku Regency, Maluku Province.

Since its acquisition by PT Merdeka Copper Gold Tbk in 2018, the Wetar Copper Mine has been continuously optimized to improve operational efficiency and maximize resource utilization. Ongoing improvement programs include the development of ore processing technologies that support the mine’s long-term operational sustainability.

As part of these efforts, Merdeka Group is developing the Acid, Iron, Metal (AIM) Plant at the Indonesia Morowali Industrial Park (IMIP) in Central Sulawesi. Operated by PT Merdeka Tsingshan Indonesia, the facility processes high-grade pyrite from Wetar into a range of value-added products, including sulfuric acid, iron ore pellets, copper sponge, copper cathodes, lead-zinc hydroxide, gold doré, and silver. Transporting pyrite from Wetar to the AIM Plant forms part of Merdeka’s mineral conservation strategy, maximizing resource utilization while reducing waste.
