Extending Life of Mine

In 2020, additional drilling and resource modeling efforts supported an increase in Phase 8 reserves to 460 million metric tons, extending the Batu Hijau mine life to around 2030.

AMNT also conducted comprehensive geological mapping, core drilling, and resource modeling and estimation across the 25,000-hectare area covered by the AMNT Production Operation Special Mining Business Permit (IUPK-OP).

The Elang deposit, discovered in 1991, is recognized as one of the world’s largest undeveloped copper-and-gold resources, classified as a Super Giant Cu-Au Porphyry deposit by the United States Geological Survey (USGS). Ongoing drilling efforts are focused on expanding the ore body and optimizing the deposit, with a definitive feasibility study expected to be completed in 2024.

Looking ahead, our exploration plans include future drilling programs at the Ladam Deposit, a predominantly epithermal gold vein deposit located southeast of the Elang Deposit. Extensive drilling has been conducted since 2020, and a detailed feasibility study, including metallurgical test work, is underway for the Ladam Deposit.

Location of The Batu Hijau Mine and Elang Deposit

The Batu Hijau Mine and the Elang Deposit are located on the island of Sumbawa, West Nusa Tenggara. Elang is located about 60 kilometers east of Batu Hijau.
