The prospect is defined by a discontinuous 1.2km long gold in termite soil anomaly along the flanks of a ferricrete caped ridge and is also coincident with a VTEM geophysical anomaly.
For instance, the international literature records terms such as laterite, petroferric contact, ferricrete, cuirasse, duricrusts, iron crusts, ironstones, ironpans, pisoliths, pisoplinthite, iron concretions and nodules.

The soil cover units consist in numerous zones of ferricrete interspersed with deep nonhydromorphic soils.
In addition to the planned RC drill programs mentioned above, an aircore drill program of approximately 3,600 metres will be used to further define gold geochemistry targets over an area of 1km2 between the Kouglaga and Konkera North Prospects where deep ferricrete horizons have limited previous conventional auger and soil geochemistry programs.

The deposit contains bedded fines, gossan material and paleosoil, comprising the waste, and the ore materials of ferricrete, mudflow, mudflow clay and mudflow clay pyrite.
Gamma spectroscopy, another potential technique, is limited to defining soil characteristics within the top 0.30-0.45 m (Grasty 1976) because gamma emissions travelling through dry soil will attenuate by about half for each 0.10 m depth travelled, masking the distinctive gamma-ray emissions of both ferricrete gravels and non-ferruginous clayey B horizons (Verboom and Pate 2003).
