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.

AMMAN continues to work on the commissioning of the smelter. The Flash Smelting Furnace, Flash Converting Furnace, and anode furnaces are commissioned and under operations. The FSF feeding has started in January 2025.
