Jakarta, 18 September 2025 — PT Amman Mineral Internasional Tbk (AMMAN), one of Indonesia's largest copper and gold mining companies, has again achieved a major international milestone. For the second consecutive year, AMMAN has been named one of the 'World’s Most Trustworthy Companies 2025' by the prominent international news magazine Newsweek in collaboration with data research firm Statista.
In the 'Materials and Chemicals' category, AMMAN ranked 4th out of 63 companies worldwide, a significant jump from its 15th position the previous year. This achievement underscores AMMAN's commitment to strong corporate governance standards and operational excellence.
The 'World’s Most Trustworthy Companies' ranking is based on an in-depth survey of over 70,000 participants across 20 countries. The assessment measures the level of trust from investors, customers, and employees. Social listening analysis further strengthens the results by monitoring public sentiment on social media and digital platforms.
“This recognition is a reflection of the hard work of the entire AMMAN team to innovate and operate continuously with the highest standards of integrity,” said Kartika Octaviana, Vice President of Corporate Communications at AMMAN. “Amid the major transformation we are undergoing, public trust is a crucial asset for us to continue growing as a modern, transparent, and sustainable mining company,” she added.
Building Trust Through Operational Excellence and Digital Transformation
In the first half of 2025, AMMAN's copper cathode production reached 19,805 tons (equivalent to 44 million pounds), a significant jump from just 635 tons in Q1 to 19,170 tons in Q2, as the smelter's performance improved post-initial commissioning. Additionally, in mid-July 2025, AMMAN successfully produced its first pure gold from the Precious Metal Refinery (PMR) facility, marking a key milestone in its expansion project.
Along with the progress of the Batu Hijau Phase 8 overburden mining activities, our mine operations continue to demonstrate high efficiency. In Q2 2025, the volume of fresh ore mining increased significantly from 1 million tons to 5 million tons. Mining activities must stay on track to achieve the annual production target.
In line with our vision to become the most thoughtful and progressive technology company in natural resources, we are actively implementing digital transformation across all company operations. This includes the development of a Minimum Viable Product (MVP) focused on optimizing copper recovery and predictive maintenance for haul trucks and heavy equipment. These efforts are tangible proof that AMMAN continues to adapt and innovate to achieve operational excellence.
