Africa Exploration and Minerals Group Advances Resource Definition in Ghana's Oti Region

Strategic Insights -

The Africa Exploration and Minerals Group (AEMG) has been working in collaboration with the Ghana Integrated Iron and Steel Development Corporation (GIISDEC) to undertake resource definition within the Gyamonome Bloc B of the Buem Formation in the Oti Region. This process involves delineating the size, shape, grade, and location of mineral deposits to support mine planning and economic evaluation. The drilling campaign began on July 30, 2024, and has reached a total of 1,426.70 meters of diamond drilling, collecting solid rock and other rock samples from underground and below the surface.

Key Takeaways:

  • AEMG has completed 1,426.70 meters of diamond drilling in the Gyamonome Iron Ore project, collecting solid rock and other rock samples from underground and below the surface.
  • The drilling campaign began on July 30, 2024, and has confirmed the potential for a significant iron ore deposit.
  • 12 additional drill pads were prepared to provide broader coverage for resource estimation and data verification.
  • Access routes and drill platforms were constructed with minimal environmental disturbance, incorporating drainage control and site rehabilitation measures.
  • Core cutting and sampling commenced in March 2025, marking a transition to the analytical phase.
  • Rock samples have been sent to Intertek Genalysis Laboratory in Australia for assay using Inductively Coupled Plasma (ICP)-Optical Emission Spectrometry (OES) and Inductively Coupled Plasma (ICP)-Mass Spectrometry (MS) techniques.
  • QA/QC protocols include the insertion of Certified Reference Materials (CRMs), blanks, and field duplicates.
  • Preliminary X-Ray Fluorescence (XRF) analysis has yielded elevated levels of base metals such as nickel, and detection of secondary minerals such as manganese, chromium, and titanium.
  • Several geological and operational challenges have affected drilling efficiency, including frequent bit wear and replacement.
  • The team has successfully navigated complex subsurface conditions through strategic drilling adjustments, safety-conscious decision-making, and strong field collaboration.
  • Progress made so far has affirmed the Gyamonome Bloc B's strong potential for iron ore and associated base metal mineralization.
