Project 5

Ground Magnetic Investigation to evaluate a gold asset Kedougou Region, Senegal

Country: Senegal
Region: West Africa
Period: 2021
Commodity: Gold
The geo-prospecting services was undertaken for evaluating a prospecting permit spanning 56 sq. km. area located in eastern part of Senegal.
Objective of the investigation was to assess structural framework in permit area in a bid to target zones of possible mineralization related to hydrothermal regime that has evolved due to orogenic deformation experienced in region, particularly in the permit area The service entailed the following scope of work,
High Resolution Ground Magnetic Survey across entire prospect in a regular pattern of 200 m line spacing in northwest-southeast orientation followed with infilling of line in 100 m spacing in selective portions in the permit.
Process, analyse & interpret the structural & lithological regime experienced in the prospect & identify potential mineralization zones for further assessment.
Recommend future prospecting schemes in target areas for detailed mapping & exploration.
A total of 374.70 LKM of on-ground survey was conducted to cover the area using GEM systems GSM19TW Proton Precision Magnetometer (PPM) equipment. Data acquired in the field has been processed to produce anomaly maps and several derivative information pertinent to interpretation of the structural features.
Interpretation drawn from several magnetic datasets led to delineation of structural framework and characterising the interpreted features in Major & Secondary categories. Major structures are aligned in northeast-southwest orientation in tandem to the regional structural trends. Secondary structures orthogonal to the major structures. Based on this interpretation 07 Zones have been recommended for further geophysical prospecting covering about 28.0 sq km (50% of the permit area). Taking reference from these 07 zones, a future prospecting program was conceived to cover target areas in 04 blocks. The future prospecting program would cover 2D Electrical Imaging (Resistivity & IP) followed with core drilling in target locations.
