【 摘 要 】

Core sampling analysis from vertical exploration wells was conducted by the statistical methods. Assayable gold samples were analyzed by the atomic absorption method, while trace elements- emission-spectral semi-quantitative method. It was determined that the grade distribution of gold and trace elements within the deposit itself does not match one of the partition laws. Applied complex mode of processing of geochemical data provided the interpretation of anomaly geochemical field structure. The analysis of geochemical association distribution showed that their structure is concentric-zonal within bulk-metasomatic halo. The geochemical association distribution, in general, is related to hydrothermal minerogenesis stages in a deposit. Based on the mining-geological Datamine studio 3 program 3-D geochemical deposit model was plotted.
