The article presents the results of research conducted on several rare metal deposits and ore occurrences within the North-Western Kalba region (Eastern Kazakhstan). The high demand for rare metals such as Li, Ta, Cs, Be, Sn, and the limited study of this region, are the driving factors behind the interest in this area. The article provides data on the geological structure of several ore occurrences, as well as the results of mineralogical and geochemical studies of granites, pegmatites, and greisen. Based on the analysis of the obtained results, it is concluded that all the rare metal deposits in North-Western Kalba formed through a unified process of differentiation of the parental magmas of the Kalba granite complex. It is suggested that the North-Western Kalba region could be considered promising for the discovery of new rare metal deposits.
