Currently, the effective use of geochemical research results is hampered by the lack of software and computer support. In this study an attempt was made to process geochemical data on multimetal mineralization of the Lower-Taiga ore cluster (NTRU) on the basis of Matlab mathematical simulation software. The analysis was carried out on more than 5000 samples taken from channel and chip sampling of mine workings, spectral, spectrographic aurometric, assay-activation, atomic absorption and chemical analyses of NTRU.
