Overview:
-Nyong Series: mesothermal/orogenic gold signatures
confirmed through alluvial gold microchemistry and IP
geophysics. -Target IP chargeability volume: ~996.7 × 10⁶ m³ -06 oriented diamond drillholes (2,015 m) covering 0,85% of anomaly. Goal: Log, model and quantify visible gold, lithology, alteration and pyrite.

Key data & findings:
i) Drilling Summary Table:

ii) Pyrite Volume:

Pyrite-bearing rock volume~8.44×10⁶ m³ → ~25.5 Mt. (~0.85% of the total anomaly→largeunexplored potential).

iii) Predicted Pyrite-Bearing Volumes and Tonnages:

Recommendations:

Geochemical results before extending oriented drilling.
