[Mali] Ashanti Gold announces first results for Gourbassi West project
Gold exploration company Ashanti Gold Corp. has announced first results for Gourbassi West from the recently completed 105 hole Reverse Circulation and Diamond Drill, 12,283 metre drill program that tested mineralization on the Kossanto East Project in western Mali.
Results presented fill-in gaps in previous drilling and test new step-out areas at Gourbassi West. The results support and expand on previously interpreted mineralized zones dipping moderately to the west.
In addition, drilling has revealed that the silicified breccia host rock is part of a “damage zone” associated with a thrust fault system.
Tim McCutcheon, CEO, said "These results come after much thought and analysis concerning the nature of mineralization at Gourbassi West. Paul Klipfel, our COO, planned important step out holes on width at Gourbassi West. Drill hole GWRC305 shows the significance of this decision. These results add important widths to the mineralized zone and support the contention that there are multiple zones of mineralization along stacked thrust faults at Gourbassi West."
Gourbassi West is the second of two principal areas of mineralization being investigated by the company at Kossanto East. The target consists of gold mineralization associated with silicified, brecciated felsic volcanic rocks along a northwest trending structural zone for over 1200m of strike length.
2018 diamond drilling revealed that the silicified brecciated volcanic rocks that host most of the gold mineralization are associated with shallow to moderately west dipping thrust faults.
Sedimentary rocks that are younger than the host volcanic rocks and occur to the east of mineralization are in fault contact with, and are overlain by older volcanic rocks.
This is a classic ‘older over younger’ thrust fault structural relation. Repetition of this pattern reveals that mineralization is associated with cross-cutting and stacked thrust surfaces.
