#KAV Kavango Resources PLC – KCB – Airborne geophysical survey commences
29th November 2023 / Leave a comment
Kavango Resources plc (LSE:KAV), the Southern Africa focussed metals exploration company, is pleased to announce the commencement of an airborne geophysical survey on its Kalahari Copper Belt (“KCB”) project in Botswana.
The Company has signed a contract with South Africa-based New Resolution Geophysics (“NRG”) for Time Domain Electromagnetic (“TDEM”), Magnetic, and Gravity surveys combined on one helicopter platform (“the NRG Survey”).
The NRG Survey will consist of 2,374-line kms at a line spacing of 500m x 5,000m across Kavango’s Block 1A and Block 1B Prospecting Licences (“PLs”)
The work expands on airborne geophysical surveying already completed by ENRG Elements (ASX:ENRG) (“ENRG”) on PL203/2016 and PL127/2017, two adjacent PLs recently acquired by Kavango (announced >>> 16 November 2023).

Ben Turney, Chief Executive Officer of Kavango Resources, commented:
“Kavango is targeting the discovery of large-scale copper/silver targets in the Kalahari Copper Belt (KCB) in Botswana.
We recently acquired additional exploration licences from ENRG Elements to complete a large contiguous land package from the town of Ghanzi to the Namibian border. Our interpretation of ENRG’s existing survey data for Prospecting Licences 203/2016 and 127/2017 supports our working theory that this area is prospective for copper/silver. We believe this potential could extend to Kavango’s other licence holdings, which have designated as Blocks 1A and 1B.
As part of our “levelling up” strategy in the KCB, we are compiling a consistent data set for all the ground we control. NRG’s airborne geophysical survey will provide us with some of the final exploration data we need ahead of defining drill targets for next year’s drill campaign.
Our recent work has confirmed physical indicators of a copper mineralising system within our ground, combined with encouraging geophysical anomalies.
Our goal in reprocessing ENRG’s existing data and combining it with the data from the airborne surveys we will fly over Blocks 1A and 1B will be to increase our understanding of the region’s mineralised potential. We will also investigate the interpreted sub-basin that could be a significant control for copper/silver deposits.“
Further details
The NRG Survey will be conducted over five PLs that make up Kavango’s Block 1A (PL046/2020, PL049/2020, PL052/2020, PL053/2020) and Block 1B (PL205/2016) licence areas. The licences are located southwest of the town of Ghanzi and adjacent to PL203/2016 and PL127/2017, two of the KCB PLs Kavango recently acquired from ENRG.
NRG is expected to commence its airborne geophysics survey on 4 December 2023. The survey is expected to take two weeks to complete, with the final data processing and delivery of products anticipated for Q1 2024.
Program objectives
Kavango is currently re-processing data from airborne geophysical surveys already completed by ENRG on PL203/2016 and PL127/2017.
The Company will combine this re-processed data with data from the new NRG surveys to test its working theory that the copper/silver prospective geological and geophysical features, which it interpreted from ENRG’s existing airborne geophysics survey data, extend onto Kavango’s Block 1A and Block 1B licences. Kavango’s geologists and geophysicists believe this could be indicative of a regional copper mineralizing system.
Kavango’s geologists wish to examine whether the stratigraphy and lithology they have begun to map on the former ENRG PLs extend on to these Blocks. They believe that ENRG’s existing data conforms to sequences in the lower D’Kar Formation seen across other parts of the KCB.
The models in Figures 2 and 3 below depict the type of fold geometry and structural trap-sites Kavango believes to underlie areas of Block 1A and 1B.
Figure 2 is a modified version of the fold geometry, showing a “preserved” as opposed to “un-roofed” dome, as well as associated mineralisation present in the fold closure at Khoemacau’s North East Fold (“NEF”) deposit on the nearby Banana Zone. Figure 3 is a schematic cross-section showing both the shear-hosted mineralisation and dilational vein-hosted mineralisation present in Sandfire Resources’ (ASX:SFR) A4 deposit.
Kavango believes there may be scope for either or both models to be present and is optimistic the NRG survey will identify these for further ground geophysics and future drill targeting.

The magnetic component of the NRG Survey will map the structure and lithology of Block 1A and Block 1B. It is anticipated that the EM component of the NRG Survey will highlight prospective subtle conductors within the D’Kar Formation and help identify structural trap sites linked to folds, faults, and shears within Block 1A and Block 1B.
The gravity component of the NRG Survey will seek to identify whether the sub-basin identified in ENRG’s data extends into Kavango’s Block 1A. Kavango believes the margins of this sub-basin could provide priority targets for trap site development and deposit formation.
Kavango will interpret these airborne geophysical data with the goal of identifying target areas for ground geophysical follow-up, which will then lead to drill target identification.

#KAV Kavango Resources PLC – KCB – Acquisition of six new PLs completes
16th November 2023 / Leave a comment
Kavango Resources plc (LSE:KAV), the Southern Africa-focused metals exploration company, is pleased to confirm completion of its acquisition of a 90% working interest in six Prospecting Licences (“PLs”) located in Botswana’s Kalahari Copper Belt (“KCB”) (the “Acquisition”)
The Acquisition provides the Company with an extensive single contiguous project area in the KCB covering 7,629km2. Kavango is now one of the KCB’s largest individual mineral rights holders.
Kavango believes its expanded project area is underlain by similar stratigraphy to that along strike of Sandfire Resources’ (ASX:SFR) A4 deposit and Motheo Mine. Analysis of existing exploration data by the Company suggests this could incorporate a regional system that contains domal structures with folded and sheared trap sites. These are key exploration targets in the search for large-scale copper/silver mineralisation.
Kavango plans to commence follow-up work in the KCB later this month, and an update on this programme will follow.

Ben Turney, Chief Executive Officer of Kavango Resources, commented:
“These new licences grant us complete control of a contiguous, prospective system in an underexplored section of the KCB, a proven copper/silver region that hosts numerous mines and deposits.
I’d like to thank ENRG Elements for its support during our due diligence process. The mapping, soil geochemistry and drilling data it has provided has been highly valuable.
Kavango has strengthened its geological understanding of its new licences by mapping their lithological sequences and stratigraphy. Meanwhile, the presence of galena and sphalerite – two important pathfinder minerals for copper mineralisation – is also encouraging.
We will now continue to advance our understanding of the new licences’ mineral potential by investigating the potential sub-basin we have identified and interpreting their structure with satellite imagery.
Both of these workflows will help us to develop priority drill targets over the coming months.“
Further details
Kavango’s six new PLs cover ground adjacent to its existing Karakubis Block next to the Namibian border. This is currently the priority focus area for the Company’s KCB copper/silver exploration programme. The new PLs are also adjacent to the Company’s South Ghanzi licence block.
In preparation for the completion of the Acquisition, Kavango carried out a detailed review of ENRG’s previous exploration work, including mapping, soil geochemistry and drilling together with historical exploration work.
As a result of this review, Kavango believes the lower D’Kar Formation it mapped across PL049/2020 & PL052/2020 (two of its Karakubis PLs) extends into PL203/2016, PL127/2017 & PL205/2016 (three of its six new PLs).
During the review, Kavango received drill samples and logs from 5,566m of historical drilling completed by Icon and Ashmead.
Kavango’s geologists have begun to interpret the lithological sequences on its new PLs by completing geological work on these drill logs in combination with systematic magnetic susceptibility measurements. The sequences comprise siltstones, carbonates and sandstones.
The Company’s geologists have also begun to compile a stratigraphy for the new PLs that they believe to match existing field mapping and conform to sequences in the lower D’Kar Formation present across other parts of the KCB.
During its review, Kavango identified visible galena and sphalerite hosted in quartz-carbonate veins in the drill core and chips taken from this area. These are two important pathfinder minerals for copper mineralisation.
Additionally, systematic pXRF analysis along the cores and drill chips has confirmed the presence of elevated copper, lead and zinc at correlatable intervals.
Finally, Kavango’s geologists and geophysicists believe they may have identified a gravity low likely related to a deeper sub-basin during a review of ENRG’s previously acquired Airborne Electromagnetic (“AEM”), Gravity and Magnetic data over the Kara Antiform. The margins of this sub-basin could provide priority targets for trap site development and deposit formation. They can be further prioritised when cross-referenced with ENRG’s historic magnetic, AEM, and soil geochemical datasets.
Background to the agreement
Kavango entered an agreement to acquire a 90% interest in the six new PLs earlier this year (announced >>> 25 September 2023) with Global Exploration Technologies (Pty) Limited (“GET”), a wholly-owned subsidiary of ENRG Elements (ASX:ENRG) (“ENRG”).
Under the terms of the agreement, Kavango has now paid a total of AUD$1.5 million in cash to acquire 90% of the issued shares of Icon Trading (Pty) Ltd (“Icon”) and Ashmead Holdings (Pty) Ltd (“Ashmead”), two of GET’s subsidiary companies. Kavango will pay GET two further instalments of AUD$500,000 within 90 days and 180 days of the acquisition’s completion.
