The eastern region of Cameroon, rich in gold resources, remains underexplored due to the geological complexity of the Pan–African basement and the scarcity of outcrops. This study aims to identify the structures controlling gold mineralization in the Batouri district by integrating gravity analyses, field observations, structural mapping, and petrographic studies. Terrestrial gravity data and the global EGM2008 model were used to detect density contrasts at different scales, allowing the identification of faults, shear zones, and intrusive bodies potentially controlling mineralization. Field investigations revealed biotite granite outcrops that are cut by fractured and altered quartz veins, together with swampy areas conducive to the accumulation of alluvial gold. Petrographic analyses show a predominance of quartz and feldspars, consistent with the occurrence of primary gold mineralization. The synthetic structural map highlighted three main lineament trends (N77–90°E, N30–60°E, and N105–120°E), providing a precise framework for designing targeted exploration grids. The integration of gravity, structural, and petrographic data reduces uncertainties in deposit localization, optimizes exploration campaigns, and guides prospecting towards the most favorable areas. These findings provide a solid basis for future detailed investigations, contributing to a better understanding of lithostructural controls on gold in a complex geodynamic context and supporting economically viable gold exploration projects.
