State-owned diversified miner PT Aneka Tambang (Antam) has announced that its Avere precious metals manufacturing plant, which is located within the Java Integrated Industrial and Ports Estate (JIIPE) in Gresik, East Java, will enter the commissioning phase in Q4 2027, aimed at boosting the company’s gold coin and bullion production.
“Commissioning is expected to begin in the fourth quarter of 2027,” Antam President Director, Achmad Ardianto, told a hearing with Commission XI of the House of Representatives (DPR) on Wednesday, July 16, 2025.
Commissioning refers to the testing phase where all equipment and systems are checked to ensure proper operation before full-scale production begins. It comes after construction is completed, but before commercial production starts.
Achmad said the Gresik plant is intended to increase Antam’s gold bar production, using domestic gold mines as raw material sources. He cited that Antam has partnered with PT Freeport Indonesia (PTFI) to process Freeport’s gold output at the new facility.
The Gresik plant is projected to process up to 30 tons of gold annually, resulting in the production of around 5 million gold coins and bullion bars. The estimated investment for the project is US$70 million (Rp1.13 trillion). Currently, the plant is still in the pre-production stage, with construction acceleration targeted for Q4 2025.
Antam signed a land purchase agreement with JIIPE for this plant on December 27, 2024. Antam’s Business Development Director, I Dewa Wirantaya, emphasized JIIPE’s designation as a National Vital Object, which provides enhanced security for operations from processing to distribution − a key reason for selecting the location.
He also noted the strategic advantage of being near PTFI’s copper smelter, which gives Antam direct access to high-purity gold (99.99 percent).
“This facility will help reduce imports and boost domestic product use, contributing to foreign exchange savings,” Dewa said on January 14, 2025
