Old gold mines in the Barramiya district, Eastern Desert of Egypt, are associated with NE–SW-trending ophiolitic ultramafic belts and their alteration zones (listvenitization). This paper integrates geophysical aeromagnetic and geological studies, including remote sensing technologies, to explore the potential for planning future development of gold mining in Barramiya, Central Eastern Desert (CED), Egypt. Utilizing remote sensing techniques and processed Landsat-8 images is valuable and successful in delineating the distribution of ophiolitic ultramafic belts with their associated alteration zones. Moreover, aeromagnetic data analyses were carried out to reveal the subsurface geologic setting, the extent with depth and the possible association with gold mineralization. The total intensity map was examined numerically for remanent magnetization content using the normalized source strength transformation (NSS) for proper delineation of the mineralization with depth. The reduced-to-pole map was subjected to a variety of digital filters and tomographic inversions. The results reveal the association of three previously productive gold mines with clear low magnetic anomalies and consequently low magnetic susceptibility in the Barramiya mine area and Um Slim. However, numerous new similar anomalies were recognized and need to be explored for possible gold mineralization. The estimated depths to magnetic sources using the 3D Euler technique range between 143 and 1125 m, while 506.7 m was the estimated average depth to sources. Such results suggest other possible locations and deep gold mineralization in the areas corresponding to low magnetic susceptibilities. These results agree well with the constructed geologic map, and the spatial distributions of different rock units were classified according to distinctive mineral assemblies of serpentinites and their spectral characteristics to improve their identifications.

埃及东部沙漠的Barramiya地区的旧金矿与NE-SW趋势的石质超镁铁质岩带及其蚀变带有关（利斯特化作用）。本文整合了包括遥感技术在内的地球物理航空磁学和地质学研究，以探索规划埃及中东部沙漠（CED）的Barramiya未来金矿开采计划的潜力。利用遥感技术和经过处理的Landsat-8影像非常有价值，并且成功地描绘了脂滑性超镁铁质带的分布及其相关的蚀变带。此外，进行了航磁数据分析，揭示了地下地质环境，深度范围以及与金矿化的可能联系。使用归一化的源强度转换（NSS）数值检查了总强度图的剩余磁化含量，以正确地描述矿化的深度。极点缩小图经过了各种数字滤波器和层析成像反演。结果表明，三个原先生产的金矿与明显的低磁异常有关，因此在Barramiya矿区和Um Slim的磁化率较低。但是，已经认识到许多新的类似异常，因此有可能需要进行金矿化研究。使用3D欧拉技术估算的到磁源的深度范围在143和1125 m之间，而506.7 m是估算的到磁源的平均深度。这样的结果表明在与低磁化率相对应的区域中还有其他可能的位置和深金矿化。这些结果与构造的地质图非常吻合，并根据蛇纹岩的独特矿物组合及其光谱特征对不同岩石单元的空间分布进行了分类，以提高识别度。
