Abstract

As a result of work using the ratio of different bands and combinations of Landsat 7 and Landsat 8 multispectral satellite images, a new combination was created, which made it possible to map mineralization zones for known deposits and identified new potentially promising mineralized zones as continuations of ore zones. The results of remote studies are provided as contours of predictive positions, which are identified by spectral anomalies in the SWIR ranges. These anomalies are confirmed by traditional methods of geological research in the field. The samples obtained along the exploration routes showed a high content of gold and associated minerals. By pro-cessing the iron index of multispectral space images, we obtained correspondence to the zones of hydrothermal changes. The ratio of increase in mineralization content is related to the distribution density of spectral halos. With remote sensing methods, field verification work and structural studies were carried out in parallel, as a result of which the impact of Quaternary tectogenesis was established, which led to a change in ore bodies to a lenticular shape
