Abstract
Antam is developing mine in Pakal Site, that supply feed ore in FeNi Plant and the export targets. The challenge is how to do ore blending as part of mine scheduling. The mining concept are, ore that is mined from pit will be stored in five different ore stockpile. Products will be produced from ore blendi ng in stockpiles. As run scheduling simulation, best scenario elected show 12.91 MWMT total material movement in first five years. The Pit will produce 10.35 MWMT product (62% for FeNi Plant and 38% for Export), 1.14 MWMT as ore inventories in stockpiles, and 1.42 WMWT Waste that will be backfilled on the mined out area. Simulation results show 80% of the material became products, 9% as an ore inventories in stockpile, and 11% is waste as backfilling material. Regarding this circumstances, Antam has figure out the mineral reserve conservation as the corporate's added value.
