Mise En Evidence De Nouvelles Cibles De Forages A Partir De L’analyse De La Fracturation Du Prospect Aurifère De Dougbafla-OUME (Centre-Ouest De La Côte d’Ivoire)
AbstractThe mining research license of Oume (PR105) is located in the Centerwest forestry of Côte d’Ivoire on Fettekro greenstone belt. This furrow belongs to the Proterozoic Birimian series of West Africa. This concession which is our study area, is sheltered by the Bonikro gold deposit, which was discovered by sampling the geochemical gold soil anomaly. All around the latter within a radius of about 15 km, ten prospects or targets were highlighted by the method of soil geochemistry. These targets or potential anomalies are currently undergoing intensive drilling to identify potential resources that could feed into Bonikro mine processing unit. It is in this perspective that the aim of this work is to locate new targets likely to contain gold indices from the use of synthetic opening radar satellite imagery. The fracturing map was obtained by applying directional filters from Sobel on the radar images (N-S, E-W, NESW and NW-SE) and Yesou gradient filter. The enhanced lineaments were extracted manually. The report of the lineament direction on the specific tools called “Rosace” showed five (5) preferential direction classes [N00 - N10], [N20 - N30], [N40 - N80], [N90 - N100] and [N120 - N140]. The analysis of the relationship between the lineaments map and geochemical signature map of the study area shows that the area is intensely fractured and describes an anomaly that overlap with coarsely elongated gold content along the Birimian formations direction. The study permitted to identify four (4) potential targets within Oume license.
