Kavango Resources plc will extend its drill programme after identifying an electro-magnetic (EM) anomaly in target area B in the Hukuntsi (northern) section of the Kalahari Suture Zone (KSZ) project, Botswana.
The company holds 14 prospecting licences for copper-nickel-PGM rich sulphide ore bodies covering 7,573.1km2 of ground.
These also include 12 licences over a significant portion of the 450km long KSZ magnetic anomaly in the southwest of the country.
Last week, the company designated the EM anomaly as target B1 which is 475m by 550m with a conductance of approximately 8,200 Siemens. The decay constant is estimated to be in excess of 350ms.
Target area B is some 12km from target C1 but lies in a separate, distinct geological setting to the A-C corridor.
DRILLING EXTENSION
Equity Drilling & Mindea Exploration and Drilling Services (Pty) will extend the current drill contract to include drilling a 550m borehole into B1.
Spectral Geophysics Ltd will perform immediate down hole electromagnetic (EM) surveys on each borehole on completion.
This aims to retrieve core from the bottom of the ‘Norilsk-style keel’ underneath.
TDEM SURVEYS
Kavango has also engaged its strategic partner Spectral Geophysics to conduct two more time domain electromagnetic (TDEM) surveys in target area B.
Six target areas have been surveyed by Spectral with drill targets identified in target areas A2, C1 and B1.
Kavango said that there were no targets in target areas A1 and D.
Data is being analysed for target area B2 and two further TDEM surveys are planned in target area B, with one targeting B1.
Chief executive Ben Turney said that exploration results for all the company’s projects this year had consistently surpassed expectations.
“While the conductance of targets A2, C1 and B1 appears to suggest they fall within the range of massive sulphides, we take a high degree of comfort from the ‘negative’ results of A1 and D1.
“The fact that the TDEM surveys have selectively identified EM conductors gives us confidence we are using the right remote sensing technology to define specific drill targets.
“While we must remain measured in our response to these upbeat developments, we must also make sure we are prepared for one or more positive drill results.”
Kavango is this year pursuing its objective of proof of concept in the KSZ.
