Jakarta — PT Amman Mineral Nusa Tenggara (AMMAN), one of Indonesia’s largest copper and gold producers, has been awarded the Best Practices in Processing title at the 4th ASEAN Mineral Awards (AMA) 2025. The recognition was presented during the ASEAN Ministerial Meeting on Minerals in Vientiane, Laos, underscoring AMMAN’s leadership in innovation, operational efficiency, and sustainability.
The company achieved a 5.6% increase in mineral recovery rates through the integration of Artificial Intelligence (AI), equipment upgrades, and process optimization in grinding, milling, and flotation. This technological leap not only boosted efficiency but also set new benchmarks for the region’s mining sector.
AMMAN’s environmental stewardship was also highlighted. The company has:
- Reduced CO₂ emissions through a 26.8 MW solar power plant.
- Improved water efficiency by 40% since 2016.
- Reclaimed nearly 800 hectares of land, planting 1.8 million trees across 99 native species.
Beyond operations, AMMAN’s social empowerment programs have delivered measurable impact in West Sumbawa. Initiatives include reducing local stunting rates by 30%, reviving traditional weaving through women’s cooperatives, and developing surfing infrastructure that supports sustainable tourism.
According to Kartika Octaviana, Vice President of Corporate Communications, the award reflects AMMAN’s commitment to world-class mining practices:
“This recognition is proof that innovation and sustainability are embedded in every aspect of our operations. Excellence in mining is not only about business success but also about responsibility to the environment and communities.”
The ASEAN Mineral Awards, held biennially, serve as a regional benchmark for best practices in mineral resource management. AMMAN’s achievement positions Indonesia as a leader in sustainable mining within Southeast Asia, while reinforcing the company’s role in advancing global competitiveness.
