Soil sampling undertaken by previous explorers defines several gold-in-soil targets but appears to be limited to the areas of in-situ stage 1 laterite or areas of erosion. Thus, whilst surface geochemistry may be used for targeting, the lack of geochemical anomalism cannot be used to discount areas of interest.
The Kalaka Project interest is held by our associated Company, Moydow Holdings Limited (Moydow). Moydow is earning an 80% interest in Kalaka the Project. Panthera holds a 45.8% equity interest in Moydow.
IP Survey
Induced Polarisation (IP) is a geophysical technique that consists of transmitting an electric current into the ground and measuring the electric potential field between two electrodes. This provides a direct measure of the resistivity of the substrate. In the particular application used, which is time-domain IP, the measurements of this induced electric field are continued after the current is switched off, providing a measure of the decay in voltage over time which measures the chargeability of the substrate.
It is known that disseminated sulphides create a high chargeability response and thus the technique can act as a direct measure of the amount of disseminated sulphides in the substrate. It should be noted that other factors can also create a chargeability high, such as saline groundwater and some clays, but these generally have a lower response than disseminated sulphides.
Some rocks such as quartz veins, silica alteration and some highly siliceous felsic units tend to be highly resistive and hence will show up as resistivity highs. Conversely, some units tend to be very conductive (for example graphitic shists and shales) and these will thus return a very low resistivity response. The inverse of resistivity is often shown as a conductivity plot to highlight these very conductive lithologies.
The IP method can thus be used to examine and map out bedrock units, some structure and alteration/mineralisation, even beneath the transported cover, albeit gold association with such mineralisation can only be proven with follow-up drill testing.
A total of 168.3 line kilometres of IP (gradient array) survey has been completed at the Kalaka Project, covering the majority of the known targets in the southern part of the tenement. This part of the tenement was chosen as it was interpreted that soil sampling is largely ineffective here, there are two areas of extensive artisanal mining activity in the south of the licence, and previous work, by previous explorers, has highlighted considerable areas with low order gold mineralisation in RAB and Aircore drill holes.
Results of the survey are very encouraging, with eight main chargeability anomalies identified along with several other anomalies on the edge of the survey area that require additional surveying to accurately define their extents. Importantly, the IP anomalies incorporate the K1A prospect which close
