Abstract

The aim of this paper is to develop a methodology for predicting the potential of future drilling, not merely on average but more specifically as a function of the grades obtained in the drilling in Chadormalu Ir on ore deposit. In most cases additional samples are collected to reduce the overall unc ertainty on the estimation. To do this, the GET function method is used to find the bore hole locations that are more sensitive in reducing the local and global uncertainty than others. This function considers the Grade of each ore block, Estimation Error and or e Thickness. Using this method, several locations for additional drill-holes are selected
