Resource estimation and evaluation.
Remember that declustered data statistics are not perfect: Applying declustering is a good idea for many drillhole data sets, but recognise that it’s not a perfect process. During optimisation of the declustering process, it should be apparent that parameter selection varies the outcome to some degree. Recall this imprecision when comparing whole-of-domain grade statistics after block grade estimation – differences may be within the precision of the declustering process and therefore not necessarily worthy of follow-up action.
