#KAV Kavango Resources – KCB – target definition on Mamuno Licences

Botswana focussed metals exploration company Kavango Resources plc (LSE:KAV) (“Kavango”) has identified a large drill target, prospective for copper, on its Kalahari Copper Belt (KCB) Mamuno licences PL049/2020 & 052/2020.



–    The Mamuno Project Area extends to the Botswana-Namibia border, beyond which Rio Tinto and Sandfire Resources hold licences directly adjacent to the west and north

–    Completion of large-scale, high-resolution soil sampling program (Mamuno 1,319 samples, 9,677 program total)

–    Identification of large drill target (the “Target”):

–    5km long x 3.5km wide area of anomalous values (+30ppm Cu)

–    Peak value of 73ppm Cu (pXRF values)

–    Geochemical anomalies conform with the mapped underlying geology

–    Follow up geophysics planned to sharpen target definition, ahead of drilling

Kavango has provided a map showing the Target on the Company’s website, via the link below:


Ben Turney, Chief Executive Officer of Kavango Resources, commented:

“This work represents the culmination of a 2022 program of 9,677 soil samples, which has already identified multiple targets elsewhere on our PLs 082/2018 and 036/2020 (26 August 2022 and 3 August 2022).

The presence at Mamuno of anomalous values to 73ppm copper, over a large area, means that this is a robust anomaly. The western KCB area has historically been unexplored due to depth of sand cover, but is now seeing an intensification of exploration activity. Kavango has managed to carry out geological mapping in the area despite the cover, and considers that the anomaly aligns with an underlying Ngwako Pan/D’kar Formation contact, which is a key control on copper/silver mineralisation in the KCB.

Kavango now plans follow-up geophysical work to sharpen the definition of this large anomaly, followed by drilling.”


Target Detail

A large geochemical feature has been identified, of up to 73ppm copper which given the soil cover is of a high tenor.

Main Zone (Cu: >30ppm, Max 73ppm)

–    Dimensions 5km x 3.5km

–    Follows the geological trend of the Ngwako Pan-D’kar Formation geological contact mapped nearby by Kavango

–    Also associated with NW-SE trending lineaments, which cross cutting structures are known to be linked to high grade copper mineralisation elsewhere on the KCB

–    Area features Kalahari sand cover, which is known to attenuate soil geochemistry values. Even with this, Kavango has identified a high-tenor anomaly relative to anomalies identified elsewhere on the KCB by other companies

–    Area has been field checked by Kavango geologists

–    The Target also has widespread elevated zinc values (>18ppm, Max 37ppm).

Planned follow-up for Mamuno Licences PL049/2020 & 052/2020


Next steps, ahead of a drill program on the Target to include:

–    Limited infill soil sampling (reducing 800m to 200m line spacing) in selected areas to refine specific drill target locations

–    Static seismic surveys (Tromino) using Kavango-owned equipment, to evaluate overburden thickness

–    Reinterpretation of regional aeromagnetic data to provide additional resolution on geological contacts around anomaly

–    Airborne or ground Magnetic/Electromagnetic (“AEM”) and Controlled Source Audiomagnetotelluric (“CSAMT”) surveys

–    A drill program is planned to follow.


Kavango Sampling Methodology

–    Excavation to 30-40cm below the surface

–    Sample is collected from bottom of hole and sieved to approximately 200g of -180um fraction

–    Sample is analysed using the company’s in-house Vanta XRF Analyser in geochemistry mode with three beams switched on for a total analytical time of 120 seconds per sample. Analyses are done using a desk-top docking station to ensure a consistent presentation distance between the sample and analyser window

–    Reference materials (of known values) are inserted after every 25 samples and at the end and beginning of each batch

–    Resultant data is then used to generate user factors for normalising the analytical results prior to interpretation

–    Selected samples are also sent to an independent laboratory in South Africa for multi-element analyses by conventional means
