Nielle Gold Project
The Nielle project consists of one licence of 300km2 located in an underexplored region, but within the Tongon-Banfora greenstone belt that is host to multi-million ounce gold resources at the Tongon Gold mine (operated by Randgold) and the Banfora gold deposit (owned by Teranga Gold).
The Nielle concession has a gold anomalous trend extending for over 4.5km and remains open along strike. This significant trend has already confirmed high-grade gold mineralisation with RC drilling and this work is demonstrating the potential for additional high-grade primary gold mineralisation.
Kodal completed a reconnaissance aircore drilling campaign with a total of 152 drill holes for a total of 5,084m completed during the 2021 field season. The drilling was planned to target the strike extensions of the defined gold mineralised zone that has been confirmed by initial RC drilling as well as target new parallel targets that were indicated in surface geochemical anomalism including the recently discovered N’Golope target area.
Gold mineralised intersections are associated with strong alteration, sulphide mineralisation and quartz-carbonate veining. The results of the RC drilling programme confirm a gold mineralised system that remains open along strike and at depth. The presence of shallow gold mineralisation is reflected in the surface geochemical anomaly, and a review of the surface geochemical anomaly highlights additional targets for drill testing.
Aircore drilling was conducted in Q2 2021 and averaged 33m depth and intersected a weathered geological profile with the intersected gold anomalism associated with quartz veining and evidence of alteration. The bottom-of-hole gold anomalism further confirms that the surface gold geochemical anomalism relates to primary gold mineralisation and is a reliable exploration tool. Kodal’s review of the historic exploration has identified further targets requiring reconnaissance drilling and this completed wide-spaced aircore drilling requires infill definition to target initial RC drilling. Follow-up and extension drilling is planned to continue to test the defined gold mineralised zone as well as continue to fully evaluate the geochemical anomaly.
