An AMI Subsidiary
Amman Mineral Industri

Amman Mineral Industri (AMIN), one of AMI’s subsidiaries, is a company that develops the copper smelter and precious metals refinery (PMR) project for AMNT, located near the Batu Hijau mine in Sumbawa, Indonesia. In addition to strengthening the Amman Group portfolio, AMIN was established in support of Indonesia’s objectives in developing the mineral downstream industry. AMIN’s smelter and PMR projects are included as one of the National Strategic Projects under the Coordinating Ministry of Economic Affairs coordination. These projects will also support West Nusa Tenggara (NTB)’s provincial government to position itself as a region with advanced mining technologies within the global map. AMIN’s projects will also be one of the two major Strategic Industrial Project Areas targeted by the provincial government of NTB for the period of 2020-2024.
Our Productivity
Achieving milestones for efficiency and sustainability
In 2020, the development of smelter and refinery facilities has progressed up to 25.55%, consistently exceeding the minimum limit set by the government at each semester.
This shows AMIN’s perseverance to comply with government regulations, despite the challenges faced with the onset of the COVID-19 pandemic. AMIN has already been able to secure all required permits for development and advanced technology for effective operations of the facilities. Currently, the company is also working on securing cooperation with several key groups in Indonesia, such as working with Medco Energi on green and renewable energy for use in the development and operations of the smelter and refinery facilities.
