London-listed Kavango Resources says three clusters of conductors at its Kalahari Suture Zone (KSZ) North project, in Botswana, are drill-ready and, if fruitful, can validate the entire KSZ North exploration programme.
One of the conductors in particular, B1, is considered by nickel/copper geophysicists to be typical of massive sulphides with pyrrhotite, which, in turn, is associated with nickel mineralisation.
“Conductance is one of the most powerful discrimination factors in nickel/copper exploration. Most exploration companies exploring for nickel and copper would want a target with a conductance as high as the B1 conductor,” says executive director Jeremy Brett.
He adds that there are more critical targets to the entire KSZ project, including the B3 and B4 clusters of conductors, and historically intersected coaly sediments. Drilling of these targets could confirm the presence of not only massive sulphides but also the ore deposit model proposed by Kavango and its senior advisers.
This would open up the rest of the project for intense exploration using more time domain electromagnetics. Brett says the only remaining step is to drill and determine the cause of these conductors.
Kavango intends to drill-test the B conductors and the KSZ North geology host environment simultaneously, along with conducting geochemistry of the gabbro intrusions near the conductors.
Kavago’s 100%-owned subsidiary in Botswana, Kavango Minerals, holds 16 prospecting licences in the country, covering more than 8 800 km2 of ground, including 14 licences over a significant portion of the 450-km-long KSZ magnetic anomaly in the southwest of Botswana.
