Relevance of the work is in the fact that the studies of the last decade confirm good prospects of the Mankhambovsky block in relation to mineral resources. These include the research in connection with the work of the Northern Scientific-Research Geological Expedition (SNGEE) under the State Program “Reproduction and Use of Mineral Resources for 2012–2020”. The territory considered in the paper is related to the mountainous, exposed part of the Northern and Nether-Polar Urals from the waterhead of the Pechora river in the south to the Manyi river-basin in the north and stretches in the meridional direction by almost 300 km including the Khanty-Mansiysk Autonomous Region – Yugra and partly – the Republic of Komi. The prospects of the Mankhambovsky block in relation to ore minerals are confirmed by studies of the last decade including some works of the Northern Scientific-Research Geological Expedition (SNGEE). More than 50 ore occurrences and about 200 mineralization points for ferrous, nonferrous, noble, radioactive and rare metal ores have been identified within the area under consideration. Iron-ore features are developed limitedly and accomplished by two ore formations – banded iron formations and skarn iron-ore one. Only copper is widely used among nonferrous metals although no significant concentrations are found, and other metals are practically not shown, with the exception of poor polymetallic mineralization in the beresitized sediments of the Laptopayskaya suite. A number of rare metals, including niobium, tantalum, beryllium, zirconium, and also rare-earth elements in complex with uranium and thorium are widely developed within the Mankhambovsky structure, with uranium and thorium leading in the ores. Radioactive elements in association with thorium, rare and rare earth metals are the leading minerals of the Mankhambovsky block. To date, there are about 20 objects of various sizes. Purpose of this work is to determine the prospects of the Mankhambovsky block for rare-metal-uranium-thorium ...
