to enhance the certainty of the grade block model, it is necessary to increase the number of exploratory drillholes and collect more data from the deposit. the inputs of the process of locating these additional drillholes include the variogram model parameters, locations of the samples taken from the initial drillholes, and the geological block model. the uncertainties of these inputs will lead...
