BOTS - Karakubis multiple trap sites identified

Kavango Resources plc (LSE: KAV), the Southern Africa focussed metals
exploration Company, is pleased to announce that ongoing processing and
interpretation of Inversions from Airborne Electromagnetic ("AEM") data have
so far identified over 90 interpreted trap-site features believed to be
associated with doubly plunging anticlinal fold and fault structures at the
6,200km(2) Karakubis Copper Project in Botswana's Kalahari Copper Belt
("KCB").

An ongoing Induced Polarization ("IP") survey programme over a diverse
selection of these features is helping to discriminate faults, folds and
possible lithologies using differences in resistivity and chargeability.

The successful completion of the first two stratigraphic holes in the 5,000m
Phase 1 diamond drill campaign at Karakubis (the "Drill Campaign"), has
validated the exploration model with three distinct achievements; firstly,
identification of lower D'Kar Formation stratigraphy, secondly the detection
of a wide zone of hydrothermal alteration, and thirdly the discovery of copper
sulphides and pathfinder minerals in the siltstones within the sequence.

The Company plans to assess as many of these as possible over the remainder of
its 5,000m and is already planning further phases of drilling.

Overview

·    Processing of the AEM, Magnetic and Gravity data was completed during
the second quarter of 2024.

·    Inversion of the AEM data was done by EMergo (Aarhus Geofisica), and
supervised by Jeremy S. Brett International Consulting Ltd., This work is
ongoing with data interpreted as it becomes available.

·    Previously processed Conductivity Depth Images (CDI) have been
integrated into the interpretation.

·    Gradient Array IP surveys and Stacked Schlumberger Sections are
underway.

·    Interpretation of the combined database has to-date identified over
90 targets with 10 priority targets selected for the Phase 1 drill programme.

·    The first 2 holes of the 5,000m Phase 1 drill programme (announced
>>> 22 July 2024) have achieved:

·    Identification of what the Company believes to be lower D'Kar
Formation stratigraphy.

·    The detection of a wide zone of hydrothermal alteration.

·    The discovery of copper sulphides and pathfinder minerals in the
siltstones within the sequence.

·    Given the extent of the opportunity the Company is looking at the
potential to expand into further phases of drilling.

·    Kavango will systematically compile all the data from its drilling
programme and use the data to vector towards a possible discovery.

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

"We are extremely pleased with how exploration of our 6,200km(2) Karakubis
Copper Project is progressing. This is an extremely large project that appears
increasingly prospective for large-scale copper deposits.

Our first drill results last week confirmed that a copper mineralising system
runs through our ground and mineralisation traps are present. This was a
highly significant event for Kavango because these are the two primary
elements for the formation of commercial copper deposits in the Kalahari
Copper Belt.

We can now reveal the scale of the opportunity in front of us.

So far, we have only processed Airborne Electromagnetic Data over about one
quarter of Karakubis. From this data we have identified 90 probable trap
sites, in the correct structural setting for possible accumulation of copper
mineralisation. Each of these potential trap sites represents a drill target
and we are now using Induced Polarization Surveys to further prioritise these.

In response to what we have learned, our team has reprioritised the order in
which we will drill the next 10 targets. Beyond that and we are putting plans
in place for further phases of additional drilling. Our goal is to vector in
on a major copper discovery.

This is a very exciting time to be involved in Kavango."

Results and interpretation

Processing, modelling and interpretation of the AEM, Magnetic and Gravity
survey data with follow-up ground IP geophysical surveys is ongoing and
systematic, with the classification and ranking of over 90 inferred trap sites
believed to be associated with doubly plunging anticlinal fold and fault
structures within the lower D'Kar Formation, which hosts all the
mineralisation, deposits and mines found to date in the KCB.

The extent of data processed to date is shown in Figure 1.

Figure 1: Kavango KCB AEM survey areas Blocks 1A & 1B with Digital Terrain
images overlaid on re-processed regional magnetic Tilt Derivative Image. The
map shows the extent to which AEM data from the survey has been processed and
modelled, with data for the central portion of Block 1A (green outline)
inverted, modelled and interpreted, while the area outlined in red is
currently being Inverted and Modelled. CDI data previously processed is being
incorporated into the interpretation (hatched area).

Kavango initiated IP Surveys consisting of IP Gradient Array surveys to detect
sulfide hot spots in the context of the AEM inversions.  We then conducted a
series of Stacked Schlumberger Sections designed to discern alteration and
sulfide mineralization signatures at depth.  These were then compared
directly with the AEM inversions to develop priority targets. Ten section
lines were initially planned over the highest priority areas identified from
the AEM, totalling over 33-line kilometres with seven section lines completed
for 25-line kilometres.

Interpretations based upon the IP Inversions appear to be comparable with
those from the AEM Inversions and are supported by the logged drill data. We
feel this combined method is developing into a powerful targeting tool.

Variations in the chemical and physical characteristics of the lithological
units, type, continuity, and connectivity of structural features and extent of
hydrothermal activity are considered to be reflected in IP response, making
this an effective tool in modelling potential trap sites, and of hydrothermal
alteration from fluid flow linked with mineralisation, Figure 2.

The successful completion of the first two stratigraphic holes in the 5,000m
Phase 1 diamond drill campaign at Karakubis has validated the exploration
model with three distinct achievements: firstly identification of lower D'Kar
Formation stratigraphy, secondly the detection of a wide zone of hydrothermal
alteration, and thirdly the discovery of copper sulphides and pathfinder
minerals in the siltstones within the sequence.

Figure 2: Cross section looking NE and showing the borehole traces for
KCBDD002 and KCBDD003. The boreholes intersected stacked sequences of units
comprising arkose, sub-arkose, sandstone, siltstone and marl, displayed by
grain size and colour coded (Arkose-orange brown, sub-arkose-light brown,
sandstone-grey, siltstone-green & marl-blue). A fault, interpreted from
the resistivity, was logged in KCBDD002 and appears to separate the different
lithologies intersected in the holes. Copper sulphides and pathfinder minerals
were observed in both holes, with pXRF spot readings returning values up to
1.8% copper (green left) and 0.36% lead (blue right).

The presence of copper sulphides overprinting pyrite, together with pathfinder
minerals along parting planes, in the structural fabric and within more porous
lithologies, is considered by Kavango to be evidence of a mineralised fluid
moving through what is interpreted to be a larger mineralised system.

Kavango plans to work through as many of these targets as it can with the
remainder of the current 5,000m Phase 1 diamond drill program.

Kavango will systematically compile all the data from its drilling programme
and use the data to vector towards a possible discovery.
