Grade Uncertainty and its Impact on Ore Grade Reconciliation between the Resource Model and the Mine

Major differences between estimated grade and actual grade are a usual problem in many open pit mines. The estimated grade is predicted in exploration stage from data obtained from boreholes, whereas the actual grade would be determined only after the mining operation. The poor reconciliation betwee...
