Abstract
During conducting of exploration numerous samples from ores, altered rocks and metal metric samples from soil-vegetation layers have been collected. All of them have been analyzed by spectral - gold-metric method on gold; have been sent on semiquantative spectral analyses on 20 elements; some of them have been analyzed by fire assay method on gold and silver and by chemical method on copper, zinc and lead. Besides, from the pan-concentrates of crushed ore samples and loose sediments have been obtained electromagnetic fractions which in case of sufficient amount of the material (more than 1 g) have also been analyzed by spectral analyses. From mineralized samples mono-mineral fractions of major sulfides and iron hydroxides have been obtained, which have been submitted for complete spectral semiquantative analysis and atomic-absorption analysis on gold and silver. All this material became the basis for geochemical interpretations. Precious metals in gold-copper-polymetallic occurrences of Gujareti-Khachkov ore field have the closest links with copper mineralization. Statistically calculated correlation ratios of quantities data (fire assay and chemical analyses) for adit10 couples Au-Ag; Au-Cu and Ag-Cu are significantly positive, accordingly – 0.90; 0.68; 0.72.
