Abstract

The comparison of OLS fitting based on exponential semivariogram models, where the range is 811.76 meters, sill is 37.23 (g/t)2 and the spherical model base, which the sill is 38.44 (g/t)2 and range is 921.87 meters, used as a basis for OK prediction. Based on these two parameters, sill and range, obtained that result of kriging variances are almost the same, namely 4.96 g/t for the exponential models, and 4.90 g/t for the spherical models. Keywords: Semivariogram, OLS and WLS fitting, Ordinary Kriging
