Abstract

Kriging prediction on gold grade with the contamination of outliers, which are grouped into two zones i.e. rich and poor zones, performed with classical and robust semivariogram comparison. Both are based on ordinary least squared fitting of spherical model. The ordinary kriging method based on robust semivariogram is used in both Original and Outlier-free data. The first scenario conducted on the Original, while the second performed on the Outlier free. Both are fitted based on the classical method and the assumption of omnidirectional.
