Existing drilling data was used to map the thickness of the fractured horizon beneath the alteration profile in order to optimize drilling locations in the Bounkani region. The useful fractured horizon, rich in fractures, was determined in four (4) areas, the most productive of which is estimated to be at a depth of 35 m below the base of the altered zone, with an estimated flow rate and linear flow rate of approximately 8.15 m³/h and 0.23 m³/h/m, respectively. Validation of the conceptual model allowed the method used to locate the thickness of the bedrock to be drilled to be judged relevant and satisfactory for improving drilling productivity.
