Abstract
This paper presents the calculation of reserves gold distribution using ordinary kriging with regional partition on the clustering of distribution zone base. The calculations of resources or reserves in mining industry depend, among other things on sample point accuracy prediction. As a part of geostatistics,kriging is a good and unbiased predictor which is based on robust semivariogram, and fitting here using ordinary least squares (OLS). However, this need foresight in determining method or pattern of sorts which is more appropriate to be used. Based on the partitioning method, it found that gold grade average is higher than the original base as shown in each of the mean value. Keywords: Semivariogram, OLS fitting, partitioning, kriging.
