Using Airborne Geophysical and Geochemical Methods to Map Structures and Their Related Gold Mineralization

Egypt’s mineral resources are an effective means of raising the country’s income. Consequently, searching for deep subsurface ore deposits is essential. In this study, we map structure and occurrence related gold-ore mineralization in ophiolitic-assemblage rocks around Wadi El-Saqia area Central Eastern Desert Egypt. Our approach combines airborne geophysical data (aeromagnetic mapping) geochemical analyses. We enhanced aeromagnetic interpreted them using edge-detection methods, such as first-order vertical derivative (FVD), analytic signal (AS), total horizontal (THD), tilt (TD), angle (TA), theta map, both grid porphyry analyses from Centre Exploration Targeting (CET), Euler deconvolution (ED) techniques. Utilizing these located main structural lineaments/contacts that control distribution hydrothermal alteration zones. addition, our use chemistry pyroxene plagioclase to describe their tectonic magmatic evolution. The results revealed NW–SE, NE–SW, N–S, E–W orientations prevalent studied area, with depths ranging less than 50 m about 600 m. To validate findings, carried out sampling, which indicates pyrite, galena, pyrrhotite, electrum contain good percentages gold (ranging 0.01–0.09 wt%, 0.03–0.1 0.12–0.14 53.55–55.01 respectively). were thus able find preferred locations mineralization, highlights value combining exploration.
