Ashanti Gold Corp. (TSX-V: AGZ) is pleased to announce results from an additional fifteen Gourbassi West drill holes from the recently completed 53 Reverse Circulation drill hole, 6073 metre drill program that tested gold mineralization on the Kossanto East Project in western Mali (see August 2, 10, 21 2017 press releases). Drill highlights include:
The results reported here and in previous press releases, significantly expand the area of known mineralization and reveal high-grade mineralization within several new locations (Table 1 and Figure 1). In particular, this batch of results confirms high grade mineralization within a newly identified northeast trending zone (GWRC131; Figures 1, 2 and 3). Mineralization interpreted from this phase of drilling and from historic drilling aligns along a ~1.3 km northwest-trending 30-70 metre-wide zone parallel to the important Mali-Senegal Shear Zone to the east (Figure 4). The presence of an additional northeast zone and its intersection with the known northwest zone presents new opportunities for expanding the gold mineralization at Gourbassi West, where shallow historic RAB holes indicate the presence of mineralization over an area >150m wide. Further drilling is warranted to test continuity and depth extensions of gold mineralization as well as parallel structures that could significantly increase any future gold resource.
Tim McCutcheon, CEO, said “these results are very exciting, as they show the size of the Gourbassi West target is much larger in both strike and width than was previously understood. Now we are discovering new mineralized structures that we will test further in our next drilling campaign.”
The Gourbassi West target now shows gold mineralization along a 1.3 km north-northwest trend that has been expanded by Ashanti drilling to 100m wide. In addition, Ashanti drill results support the interpretation of a new northeast-trending mineralized zone that intersects with the main Gourbassi West mineralized zone and continues on to the northeast an unknown distance (Figure 1). The host volcanic breccia is part of an extensive felsic volcanic complex inferred to be near the top of the local greenstone belt sequence, the most common position for large gold deposits to occur in felsic rocks of greenstone belts. Key structural controls appear to parallel the Senegal-Mali and Main Transcurrent Shear Zones (Figure 4) as evidenced by the alignment of mineralization parallel to both features.
Table 1: Highlights of Gold Intercepts GWRC131 to GWRC145
|Hole #||From (m)||To (m)||Interval (m)*||Au (g/t)|
|GWRC137||no significant intercepts|
|GWRC143||no significant intercepts|
|GWRC145||no significant intercepts|
*Intervals are intercept widths in drill hole and not true widths. There is insufficient geologic information to determine true widths at this stage of the project. Drill holes are oriented to provide the best intercept for the interpreted dip direction of mineralization.
**One sample interval missing

Note northeast and northwest trends parallel the Main Transcurrent and Senegal-Mali Shear Zones, respectively. The locations of cross sections reported here are shown.
Figure 2. Cross section 5950 showing results from historic drilling (GRC46 and 47) and three holes reported here and previously (GWRC129, GWRC130, and GWRC131). The mineralized zone to the left corresponds with the newly identified, northeast-trending mineralized zone and hosts high grade mineralization.

Figure 4: Regional geologic map of the Kedougou-Kenieba Inlier, the most northwesterly exposure of Birimian rocks in the West African craton. The Kossanto East property lies between two regional structures, the Senegal-Mali Shear Zone and the Main Transcurrent Shear Zone both of which feature prominently in localizing mineralization for numerous gold deposits. Structural relationships on the property suggest that structures parallel to these shear zones pass through the property and control mineralization.
About Kossanto East Project
The Kossanto East Project is a 66.41 km2 concession in the prolific Kedougou – Kenieba Inlier, the northwestern most exposure of Birimian rocks in West Africa and host to the Loulo and Sadiola group of world class gold deposits (Figure 4). The Property hosts two principle historically drill-tested targets, Gourbassi East and Gourbassi West (Figure 1) and several surface anomalies identified in historic surface samples and Rotary Airblast (RAB) drill holes. Geochemical anomalies identified by previous explorers and Alecto Minerals PLC led to drill testing and successful intersection of gold mineralization.
