A metamorphogenetic-metasomatic garnet ore occurrence, known as Vysota-181, is located in the Louhi District, Russian Karelia, which is part of the Arctic zone of the Russian Federation. The study of the ore occurrence has revealed many productive rock varieties. Various types of garnet ore have been identified, based on their distribution, mineral composition and industrial properties. Garnet is considered as a promising complex non-radioactive source of critical strategic rare-earth metals (TR = Y+La+Ce++Lu) and scandium. The micro-component chemical composition of the garnet from its concentrates derived from various ore types was analyzed. It has been shown that pyralspitic garnet from sialic ore varieties contains economic concentrations of scandium (Sc203 177.3196.8 g/t), a major useful component, and that yttrium-group elements (YTR = Y+Sm++Lu) predominate in the composition of associated TR (TR203 130.2139.2 g/t, the percentage of YTR203 is 91.697.2 %). The rare-metals concentration (R) in garnet from apobasic ores (Sc203 72.2 g/t, TR203 163.3 g/t) is below the minimum economic concentration. The predicted resources of garnet and R in the various ore types composing the rock massif which could be quarried by the open-pit method were estimated. Garnet resources in mafic ores are 5.582 t, R resources in the garnet are (t): Sc203 403, TR203 911, including Y203 557, YTR203 871. The total garnet resources with economic scandium concentrations in the sialic ores of various types are 5.633 t, R resources in the garnet (t) are: Sc203 1099, TR203 776, including YTR203 714, Y203 468. Vysota-181 is a medium-sized ore occurrence, based on predicted scandium resources in garnet from sialic ores.
