摘要：Geostatistics was applied for the parameters optimization in the estimation process for the Shambesai gold deposit in Kyrghyzstan. Surpac and Supervisor were used as the main geostatistics analysis and block model estimation software. Refereeing to the characteristics of the mineralization type of the Carlin gold deposit, parameter optimization methods were used at different stages of estimation: the sampling spacing, top-cut, proportional effect and mixed distribution were researched for creating robust experimental variogram; logarithmic model was used for model fitting and zonal nesting method was applied to calculate the best fitting variogram fitting curves; parameters of slope of regression, Kriging efficiency and block variance were used for the optimization of block model estimation parameters, and finally the resource was completed with reasonable setting and best accuracy.
