     volume-variance relationship is one of the most important methods to show reserve estimation results, that is so suitable in short time mine programming, especially in quarters which faced with high grade gradient such as porphyry deposits. main target of this paper is to calculate optimization extraction blocks to achieve to desired grade deviation for mineral processing plant using geostatistical methods in five activated benchmarks in sarcheshmeh copper mine. utilized data include blasting boreholes drilled in first six month of 1386 and exploration boreholes which have the same blasted borehole coordinate in five active bench mark of sarcheshmeh copper mine. they were combined with each other after approved that these two groups’ data haven’t had any systematic error. for achieving to high accuracy estimation variography was applied to study spatial regression between samples and spherical models were fitted to each theoretical variograms. the sill of variograms in all benches was standstill but the effective radius shifted in various directions. variogram maps were used to show appropriate anisotropy and residual analysis to study variogram accuracy of fitted model's parameter to each variogram. at last, by calculating the optimized parameters of variogram, loaded tonnage in one shift (30000 tone per shift), volume-variance and selective mining unit variance relationship, the number of optimized extraction blocks for achieving to desired variance (%0.08) was estimated between 80 to 100 blocks.
