Potential iron ore zones in the northern Congo Craton

Mining mapping in Cameroon is an important concern of public and private authorities in the evaluation of the potential of Cameroon’s subsoil for useful mineral substances. In order to increase the knowledge of Cameroon’s metalliferous resources, we undertook the mapping of potential iron mineralization zones of the northern edge of the Congo Craton (2°30’0'N - 3°30’0'N and 12°0’0'E - 13°0’0'E) by processing aeromagnetic data. These data were processed with several operators (reduction at the equator, polynomial method, frequency filtering and upward extension) using Geosoft and Surfer software. The analysis and interpretation of the regional and residual magnetic anomaly maps obtained, allowed the definition, in addition to Nkout (known deposit), of five other zones with iron mineralization of varying importance: Dindan on pyroxene orthogneiss; Meulok on pyroxene orthogneiss, greenstones, granites and granitoids; Oding on pyroxene orthogneiss, granites and granodiorites; Djoum on pyroxene orthogneiss, greenstones, granites and granodiorites and at Ngom on granites and granodiorite.
