Contribution of Induced Polarization to the Identification of Mineralization in the Agnibilékrou Department (Eastern Côte d’Ivoire)

The chargeability maps of the Siakakro, N’Guessankro, and Mossikro sites (Agnibilékrou Department, in the east of Côte d’Ivoire) are established from induced polarization (IP) measurements. These maps reveal both polarizable and weakly polarizable structures, with anomalies primarily oriented NE-SW. These orientations, influenced by geological faults, facilitate the migration of hydrothermal fluids and the potential formation of mineral deposits. The zones with high chargeability are mainly located in the center and east of the sites, suggesting the presence of sulfides and representing promising targets for mining exploration. The weakly polarizable areas are associated with sandy-clay formations and non-conductive materials, limiting their mining potential. However, their proximity to faults, especially at N’Guessankro, justifies further investigations to identify potential hidden mineralization. In summary, the zones with high chargeability, particularly at Siakakro, should be prioritized for exploratory drilling. Further exploration, particularly around geological contact zones, is necessary to assess the economic potential of these anomalies.
