Ferkessedougou North is located in northern Cote D’Ivoire directly adjacent to Burkina Faso’s southern border. A new style of gold mineralisation was discovered in sheared granitic dykes and their contacts with metasediments resulting in a 17km long gold-in-soil anomaly identified on the permit in FY16/17. The greenstone belt found on the licence is the same as the Ferkessedougou permit and abuts the border with Burkina Faso. Rock types in the permit are mapped as “schists”, granite and granodiorite. There are extensive artisanal workings in the permit.
Drilling to date has tested only a very small portion of gold-in-soil geochemical anomalies which extend over 17km of strike and a width of 2-3km.
Previous Exploration Activity
A PARTNER FUNDED RC drill program (Figure 1) was completed totalling 80 holes and 4,989m with encouraging results including:
- FNRC016: 25m at 3.06g/t Au from 64m, including 13m at 5.35g/t Au (stopped in mineralisation, last 4m averaged 13.78g/t Au)
- FNRC003: 4m at 1.20g/t Au from 25m
- FNRC068: 9m at 1.47g/t Au from 39m
- FNRC047: 2m at 5.44g/t Au from 45m
- FNRC001: 13m at 0.97g/t Au from 4m
Better results showing large cumulative widths are shown on the following cross section:
Potential to make a large gold discovery here is significant as the gold is associated with granodiorite dykes, many of which may be located within the gold anomalous zone. The geological interpretation (above) shows interpreted granodiorite dykes from a recent aerial magnetic survey over the area, most of which have not yet been trenched or drilled.
