Modeling of KUNSU ORE Body in the Kumasi Basin Northwest of Kumasi, Ghana

Abstract

Available data consisting of geochemical assay dataset soil, trenches and drill holes assays from previous exploration works was used to model and determine the orientation of the gold prospect at Kunsu. The main aim of this study was to use available data from previous exploration works on Kunsu property to model and determine the orientation of the gold deposit and also compare previous trench assay results with re-trenching assays. To accomplish the aims of this study, the preferred fast and reliable Interpolation Kriging techniques related to Leapfrog Geo and Arcmap softwares in the mining and exploration industries were used to generate two and three-dimensional geological models of Kunsu gold prospect. Interpolation kriging technique aided a better understanding of the dataset used to model Kunsu gold prospect and its attributes in a form of model images and maps (prediction). Interpretation of the model shows that Kunsu ore body trends in line with the regional geological structural direction of Ghana, which is northeast-southwest along strike. Re-trenching assay values also did confirm previous trench assay results and did indicate extension of gold mineralization across strike. The study area has delineated promising areas for further exploration works that could enhance the mine potential of the concession.
