Abstract |
Gold mining in Egypt's Central Eastern Desert has a rich history dating back to the Old Kingdom period. Recent years have seen renewed interest from international mining companies, with several potential areas for gold mining having been identified. The deposition and occurrence of gold in the region have been extensively studied, with over 100 areas of deposition identified. Aeromagnetic and radioactive surveys have been instrumental in locating gold occurrences in the study area, utilizing data from these techniques to identify potential gold deposits. This study utilized geophysical data, including total aeromagnetic intensity (TM) and radiometric data, to identify hydrothermal zones and locate potential areas of gold occurrence. The radiometric ternary map was used to refine the search for gold deposits. Magnetic data were analyzed to determine the structural framework of the area, facilitating the identification of regions with a high potential for gold occurrence. By integrating these geophysical data sets, the study provided a comprehensive understanding of the geological features and potential for gold mineralization in the study area. The study area underwent a detailed analysis using edge detecting and radiometric techniques to determine its structural and geological characteristics. The area is divided into four sections by three shear zones, with high magnetic anomalies observed in the southeastern part. The radiometric data revealed that gold occurrence is associated with hydrothermal alternative zones, identified using the K/Th ratio and radiometric ternary map. However, not all of these zones contain gold, and the area's structure and magnetic suitability must be considered when selecting suitable locations for gold extraction. The study area presents a promising opportunity for gold exploration, with the integration of edge detecting and radiometric analysis being crucial in identifying suitable locations for exploration. |
