Predictive Discovery Ltd’s (ASX:PDI) soil sampling has extended the gold anomalous zone to more than 14-kilometres in length at the Boundiali North project in Côte D’Ivoire.
The infill sampling program on a 400 by 100-metre grid was carried out by Predictive’s joint venture partner Toro Gold Limited.
Two higher-grade anomalies
Within the zone, there are several large coherent higher-grade anomalies including a Northern Zone, which is 1.5-kilometres-long and 900-metres-wide with peak values of 707ppb and 579ppb gold.
There is also a Central zone, which is 2.7-kilometres long with peak values of 317 and 414 ppb.

Predictive’s managing director Paul Roberts said: “These soil results have exceeded our expectations with the zone of gold anomalies now over 14-kilometres in length, substantially larger than the soil anomaly over the Nyangboue prospect to the south.
“Importantly, even with the current broad sample spacing, we are seeing a series of coherent, multi-line anomalies which offer clear focus for anticipated drilling in 2019.”

Toro’s soil sampling program builds on a previously completed soil program which identified a 13-kilometre-long zone of gold anomalies with higher gold values including 1,185, 806 and 626 ppb.
There were 2,157 additional samples collected in the infill program, which add to the initial results from 1,356 samples.
The anomalies are clustered around the inferred north-south Nyangboue structure which passes through the Nyangboue gold mineralised zone, which was discovered in 2016.
A series of coherent multi-line gold anomalies have been identified.

Roberts said: “The joint venture has been following a methodical strategy of exploration across the permit and plans to undertake further infill sampling to help refine the anomalies.
“We are excited by this large new anomalous zone which complements the known Nyangboue mineralisation on the adjacent permit to the south.
“Between the two zones, we see good potential for the discovery of large tonnages of gold mineralisation on what appears to be an important gold mineralised structure.”

The Northern and Central zones are likely candidates for reverse circulation (RC) drilling in 2019.
Toro will this quarter complete further infill sampling to a 200 by 50-metre grid on areas of interest.
Follow-up exploration in the first half of 2019 is expected to include trenching, airborne magnetics and RC drilling.
Predictive is focused on 12 projects across West Africa’s Mali, Côte D’Ivoire and Burkina Faso, a proven and prolific gold region.
