Many of the openpit mines suffer from the lack of reconciliation between estimated and actual grades. in a mining operation, grade reconciliation is the comparison between the values of the estimated grade calculated in exploration stage and the actual grade obtained from more reliable data such as blast holes samples. many different factors affect the degree of reconciliation in a mining.
