Abstract
One of the basic tools in the geostatistics is the semivariogram which explains the variability of data at a specific distance and direction. The purpose of this study was to obtain a theoretical semivariogram models based on a robust experimental semivariogram by using LP, OLS and WLS methods. In data processing and fitting semivariogram using Microsoft Visual Basic and the Program R. From the results of a case study using the LP method, OLS and WLS method, the spherical semivariogram model is obtained with the sill as follows: 40.62 (g/t)2 ; 38.44 (g/t)2 ; 47.80 (g/t)2 and range as follows: 884.29 m ; 921.87 m ; 1139.96 m. As for the exponential semivariogram models sill obtained as follows: 78.60 (g/t)2 ; 37.23 (g/t)2 ; 50.72 (g/t)2 and range as follows: 216.91 m ; 811.76 m ; 1608.82 m
