Establishment of geophysical criteria for forecasting promising areas for rare metal manifestations within the Akmay-Katpar ore zone. To achieve this goal, the mineralogical composition of the ore-containing medium of the Akmaya deposit was studied, and their changes due to the functioning of hydrothermal solutions, leading to changes in the petro physical characteristics of the ore deposition medium. At the same time, three-dimensional models of the deposit built in the MicroMine program were used and analyzed, as well as geophysical cartographic and geological materials for this deposit. We considered the mineralogical composition of hydrothermally altered and unchanged rocks of the deposit in question (hornfels, skarns), as well as their density and magnetic properties. The mineralogical composition and their petrophysical characteristics formed the basis for the analysis of geophysical anomalies associated with hydrothermally altered rocks of the Akmaya deposit. The results obtained allowed: 1) explain the nature of the geophysical anomalies created by zones of hydrothermally altered rocks based on the analysis of their mineralogical composition with petrophysical characteristics; 2) outline the ore stock and the area of distribution of the main orebearing veins and veins based on the analysis of magnetic exploration data. The practical significance lies in the use of geophysical criteria for predicting the areas of hydrothermally altered cities as a prospecting sign of the discovery of ore deposits.
