A » In mining, the cut-off grade is the minimum concentration of a mineral in ore that must be present for the ore to be economically viable for extraction. It determines the point at which material is considered ore and can significantly impact the profitability of a mining operation. Adjusting the cut-off grade can influence both the size and the value of the mineral reserve.
