Botswana focussed metals exploration company Kavango Resources plc (LSE:KAV) (“Kavango”) provides an update on drill targeting at its Kalahari Copper Belt (KCB) licence PL082/2018.
– Large-scale, high-resolution soil sampling program completed ( 3,178 samples)
– Confirmation of two major drill targets (the “Targets”):
– Northern Zone, 8km strike length
– Central Zone, 27km strike length
– Peak value of 118.8ppm Cu (pXRF values)
– Geochemical anomalies conform with the underlying geology previously mapped by Kavango
– Strong indication of in-situ mineralisation
– PL082/2018 is a potential analogue to Khoemacau’s Banana Zone deposit, immediately to the south of Ghanzi Ridge (total high-grade resource of 55.8Mt @ 1.1% Cu & 16.4g/t Ag)
– Kavango has provided a series of maps showing the Targets via the link below:
Ben Turney, Chief Executive Officer of Kavango Resources, commented:
“Leading on from the work completed on PL036/2020, as reported on 03 August 2022, our team has worked rapidly to complete a further substantial soil sampling program on licence PL082/2018, under the Kavango earn-in agreement with LVR Geoexplorers.
The presence of anomalous values to 118ppm copper is significant in terms of this project’s prospectivity. These results, combined with the mapped geology and the existing Kavango AEM data, has enabled us to identify two targets of considerable strike length (8km and 27km) to test with drilling. Our targets have notable similarities with other recently drilled targets in this area.
I am presently in Botswana with Hillary Gumbo and Brett Grist. While we are here, we are meeting with drill contractors and look forward to our maiden KCB drill campaign.”
Two linear geochemical features anomalous for copper have been identified:
a) Central Zone (Cu: >30ppm, Max 118.8ppm)
– Follows the geological trend of a sub outcropping anticline. This anticline forms the dome that hosts the Zeta and Plutus Deposits to the North East. The elevated copper values are postulated to represent a possible leakage zone from a redox contact underneath
– This unit has been mapped to extend over the entire length of the Prospecting Licence (PL), extending over some 27km, and is also characterised by a zone of elevated magnetic response
b) The Northern Zone (Cu: >30ppm, Max 39.7ppm)
– A robust anomaly extending over 8 km of geological strike length has been identified
– This occurs in an area with no outcrop (under Kalahari cover)
– This is located on the edge of a magnetic high, which bears similarities to the Ourea and Quirinus deposits identified by Discovery Metals in 2009. These deposits are interpreted to be on the limbs of tight anticlines
– Previous work by Kavango identified an AEM conductor in this area extending over approximately 8km and 400m at its widest. This coincides with the geochemical northern zone identified in this latest work
Both targets also have widespread elevated zinc values (>60ppm, Max 87.2ppm) levels.
Planned follow-up for PL082/2018
Next steps, ahead of a drill program on these targets, to include:
– Review and integration of existing Kavango AEM data
– Limited infill soil sampling (reducing 800m to 200m line spacing) in selected areas to enable final definition of drill targets
– Static Seismic surveys (Tromino) using Kavango-owned equipment, to evaluate overburden thickness
– CSAMT aimed at providing resolution of targeted anticline structure and ensure optimal drill direction is selected
A reverse circulation (‘RC’) drill program will then follow.
Elsewhere, the KCB Targeting Program remains ongoing on the Mamuno licence package. Results are expected shortly.
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
