Determining the different cut-off grades in a mine

2017-9-25 · In mine planning process, the cut-off grade is determined prior to producing the reserve physicals. The different cut-off grades are the break-even cut-off grade (BECOG), incremental cut-off grade (ICOG), mill cut-off grade (MCOG), and resource cut-off grade (RCOG). The BECOG is the one used for producing the reserve stope shapes and reserve
