PT Amman Mineral Internasional (AMMAN), through its subsidiary PT Amman Mineral Nusa Tenggara, which operates gold and copper mining in West Sumbawa Regency, West Nusa Tenggara, has announced plans to commence its first copper cathode production soon.

"The first copper cathode is expected to be produced by the end of March 2025," said AMMAN President Director Alexander Ramlie in a statement from Mataram on Thursday.

Ramlie stated that the expansion project continues to progress under strict safety standards to ensure the long-term reliability of the facility.

According to him, the smelter's operational component testing is still ongoing, with the successful production of the first copper anode on February 12, 2025.

"As we transform from a concentrate producer to a copper cathode and gold bullion producer, the company faces technical challenges, including optimizing processes and equipment performance, which are crucial for a smooth transition to full-scale operations," Ramlie added.

Throughout 2024, AMMN recorded a significant increase in mining productivity and the production of copper, gold, and concentrate—each exceeding performance guidance by 6%, 7%, and 6%, respectively.

This year also marks a historic milestone for gold production at Batu Hijau, West Sumbawa, primarily driven by high-grade ore from Phase 7.

Furthermore, Ramlie highlighted that ongoing efficiency efforts have maintained the company’s position as one of the world’s lowest-cost copper producers.

"By integrating operations, fostering a renewed corporate culture, and leveraging advanced digital capabilities, we are strengthening the foundation for sustainable growth and long-term value creation," he concluded.
