Overview
– BIF mineralization in structurally complex terrain. – Ground-magnetic anomaly ~500 Mt to assess. -14 oriented drillholes (~2,000 m) covering 14 % of anomaly. Goal: Validate BIF tonnage, assess band continuity, and
structural control.

Key Data & Findings
i) Drilling Summary Table

AMPG= Amphibolites; BRE=Breccia; IFG=Magnetite
AMPG+Gneiss;Myl=Mylonites; Sap=Saprolite

ii) Tonnage Estimates

iii) Comparison with other Cameroonian deposits:

Recommendations:

Assays and infill orienteddrillingtoconfirm. Petrophysical calibration (mag pen &density).
