Integrated Geophysical Prospecting for Gold Mineralization in 02 concessions, Mandiana Region, Guinea

Country: Guinea
Region: West Africa
Period: 2022
Commodity: Gold
The geophysical prospecting program was undertaken to evaluate two prospecting permit spanning 30-hectare & 95 hectares in eastern part of Guinea, bordering Mali. Objective of the investigation was to assess structural framework in the concession to target zones of possible mineralization evolved due to orogenic deformation in the sedimentary formation. The services entailed following scope of work,
High Resolution Ground Magnetic Survey covering the areas at 50 m line spacing in continuous data acquisition mode
2D Electrical Imaging (Resistivity & IP) covering the anomaly areas identified in magnetic results, generating 2D sections to a target depth of 80 m.
Interpretation of structural features & chargeability zones in sub-surface based on above studies.
Comprehensive analysis of geophysical data & geological attributes to demarcate zones of potential mineralization.
In this program a total of 25 LKM of Magnetic survey was conducted (cumulative of both the concessions) with 2D Electrical Imaging in cumulative 8 LKM of survey length. The results indicated presence of North-South trending structures; a few of such structures appear to be associated with high chargeability zones (potential gold mineralization signatures) bounded within the sedimentary strata. The results hold importance in identifying the zones for drilling & defining the mineralized body underneath. This study also put forth the groundwater condition for exploitative purposes.
