This article presents the results of an interpretation of the territory of the Olon-Ovoot ore cluster using medium and high spatial resolution satellite images. The interpretation is based on the Sentinel-2 image, which has been orthorectified and reduced to a common spatial resolution (10 m). Indices of iron hydroxide and iron silicate in Sentinel-2 images are used for selecting areas. The subpixel structure is analyzed using high spatial resolution satellite images from the Google Earth computer program in order to identify the areas of concentration of quartz-carbonate veins in Sentinel-2 images. The structural and morphological interpretation with lineament extraction has not required spectral domain analysis in high-resolution images. Remote sensing data interpretation have made it possible to significantly clarify the geological structure of the territory and improve from the mapping scale from 1 : 200 000 to 1 : 20 000 for key areas. The fusion of satellite images of different functional scales has led to an order of magnitude increase in mapped geological features (e.g., dikes). Detailed mapping of the territory makes it possible to come close to geo-information modeling of geological structural elements, i.e., leading indicators.
