Iron Ore Reserve Calculation: More Than Just Tonnage A geological resource does not automatically become a mineable reserve. For iron ore, reserve estimation depends on the integration of: • Geological interpretation & domain modelling • Block model and grade estimation • Density and cut-off grade • Mining recovery & dilution • Pit optimization and slope constraints • Economic and processing parameters • Reconciliation between model and actual production A small change in one parameter can significantly affect the final reserve. The key is not simply to calculate more tonnes — but to define tonnes that are realistically mineable, economically viable, and supported by geological confidence. Better Geology → Better Model → Better Reserve → Better Mine. #IronOre #ReserveCalculation #ResourceEstimation #GeologicalModelling #Mining #Geology #Geostatistics #MinePlanning #MineralResources #MiningEngineering
