Methodology
- 1
Reinterpretation of airborne geophysical surveys (U, Th, K spectrometry) and selection of priority anomalies.
- 2
Tight-spaced ground radiometric grids using high-precision RadEye scintillometers with GPS georeferencing.
- 3
Background control, anomaly threshold calculation and delineation of radiometric halos.
- 4
Correlation of anomalies with lithological structures: mafic dykes, granodiorites, intrusive granites.
Deliverables
Georeferenced radiometric contour maps
Exportable field measurement database (GIS)
Ranked targets for trenching and drilling
Interpretation report with recommendations
Field case
In the Tiferchai area, follow-up of the G North and G South airborne anomalies led to trenches and inclined RC holes that returned mineralised intersections from surface.
