Due to the dense vegetation and remoteness of the area an airborne geophysical survey was opted as the most efficient method of conducting the survey. The aerial survey would supply best results possible in the shortest time frame. A VTEM geophysical survey were planned to cover EL 1025 and 1173 and the total line kilometres planned amounted to 1078km.
The VTEM geophysical survey were conducted by Geotech Ltd. and commenced 1 May 2016 and was completed by 20 May 2016. The survey totalled 1078 km of geophysical lines (245km within EL1173 and 833km within EL1025).
The preliminary data and results of the VTEM survey indicated numerous anomalies and conductive units within the project area. The results of the survey are currently still being processed but on completion, will assist in the demarcation of potential trenching and drilling targets.
As a result of the geophysical survey a large anomaly can be seen in the north eastern and south eastern portions of the project area Figure 2 above.
The pink and red regions of the geophysical map, indicates stronger underlying conductors that correlate with the graphite occurrences obtained through the past geological surface mapping, trenching, and drilling programmes (Figure 3 below). This would suggest that there is potentially a high probability for lateral continuation of the conductive units throughout the license area.
Consolidated Africa Limited are planning to investigate the anomalies, mid-July, by means of conventional trenching in order to:
1) investigate the subsurface graphite occurrences;
2) investigate the lateral extensions and continuity of the ore body; and
3) obtain a bulk sample to perform metallurgical test work on to determine the quality and grade distribution across the license area.
