PT Amman Mineral Internasional Tbk functions as a major copper and gold producer across Indonesia, overseeing a comprehensive range of activities from exploration to refining. The company maintains significant interests in the operational Batu Hijau mine and the developing Elang project, both situated on Sumbawa Island. Beyond its core mining ventures, it offers skilled personnel and administrative support for mining and related operations. A key strategic focus involves the construction and operation of advanced facilities for copper concentrate smelting and precious metals refining, which achieved 95.5% completion by mid-2024, with commissioning initiated shortly thereafter and full operations expected in late 2024 or early 2025. These facilities are designed to produce copper cathodes, gold and silver bullion, and sulfuric acid, transforming the company into a fully integrated producer and adding substantial value to its output. The company also manages liquefied natural gas infrastructure and power generation, including a substantial solar power plant, alongside investments in real estate, hospitality, and aviation services.
