EXTENDING MINE LIFE
Geological surveys indicate that the mineral reserves at Batu Hijau are sufficient to extend the life of the mine through Phase 8 until at least 2030. AMNT assesses that excavation of these reserves will remain economically viable during this period.
AMNT also conducted geological mapping, core drilling, and resource modeling and estimation in the Elang and other blocks included in the AMNT Production Operation Special Mining Business Permit (IUPK-OP) area of 25,000 hectares. The Elang deposit, discovered in 1991, is 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). In the immediate post-acquisition period from 2017 to 2021, AMNT drilled 753 holes along 150 kilometers. A definitive feasibility study for the Elang project is scheduled for completion in late 2023.
LOCATION OF THE BATU HIJAU MINE AND ELANG PROJECT
The Batu Hijau Mine and the Elang project are located on the island of Sumbawa, West Nusa Tenggara. Elang is located 56 kilometers east of Batu Hijau, accessible by road along the south coast south coast route towards Lunyuk or the northern route via Sumbawa Besar.
