ABSTRACT: The Yanfolila study area is located in the province of gold, south of Mali. Gold is the main mineral resource of Mali. No enough reserve deposit, so there is a need to assess gold deposit. To evaluate the gold deposit, the appropriate method is as follows. The first task is the geological interpretation of study area, which has been one of the major works. The second task is to interpret geochemical soil data. The processing of geochemical data requires the most commonly used methods of spatial analysis. We tried to delineate new target areas for finding undiscovered gold deposits. Finally, the integrated interpretation maps coming from the combination of the different map, referring to the fault information which is verified during fieldwork. Some faults are relatively small scale, widely distributed, and configured for various levels of influence on gold mineralization. In this case, the Banifing fault system is the factor controlling the mineralization process in the region. The findings show two targets delineated in the study area. Solona (target 1), the contours of this zone coincides with igneous rock, which has been encountered as a highly altered material. Target 2 is located in the center of Yanfolila area, and it is less important than target 1.
