The paper focuses on the identification of iron oxides in oxide ores using remote sensing methods, with the Kyzylkiya copper deposit in Abay Province, Kazakhstan, serving as a case study. Remote sensing accelerates the process of identifying and mapping minerals, reducing the need for costly and time-consuming fieldwork. The study utilizes data from Landsat 8 OLI/TIRS, ASTER satellites, and UAVs equipped with advanced cameras. These tools provide detailed, high-resolution images critical for identifying iron oxide-containing minerals. Spectral ratios, such as Landsat 8’s B4/B2 and ASTER’s B2/B1, are employed to establish thresholds that enable precise mineral identification. These thresholds facilitate the delineation of zones rich in copper and iron minerals. Modern software solutions like ArcGIS Pro, ENVI, and Agisoft Photoscan are used to process the data, allowing for the creation of accurate mineral distribution maps. Aerial photographs, emphasizing the brown rust-like appearance typical of iron oxides, are instrumental in confirming the surface presence of these minerals. Field surveys and laboratory tests support the reliability of these remote sensing methods, demonstrating the effective integration of ground-based techniques with satellite data. This integration enhances the accuracy of mineral zone mapping, potentially reducing exploration costs and improving the efficiency of geological studies.
