SnapshotTogether, Batu Hijau mine and the Elang development project, form the fifth-largest copper-gold mining complex in the world in terms of copper-equivalent reserves.

From 2000 to 2016, Phases 1 through 6 were mined at Batu Hijau. Currently, Batu Hijau is in Phase 7 of its ore mining plan.

In 2021, AMNT initiated the Phase 8 pit cutback, which involves stripping activities expected to continue until 2026. Phase 8 ore production is projected to commence in 2025 and extend the mine's life after Phase 7 ore is depleted, continuing until 2030.

Concurrently, AMNT is advancing the Elang development project. AMNT began a definitive feasibility study for Elang in 2023, with the study anticipated to be completed in 2024. The study will inform the development of a mining operation at Elang, designed to begin production in 2031. The expansion projects, particularly the processing plant, are designed to accommodate the ore from Elang, which is expected to remain active until near 2050.
