ZIM -- Assays confirm Nara gold mineralised system

Kavango Resources plc (LSE: KAV), the Southern Africa focussed metals
exploration company is pleased to announce the receipt of assay results for
its recent diamond drilling programme at the Nara Gold Exploration Project
("Nara") in Matabeleland, southern Zimbabwe.

The assay results confirm the presence of a gold mineralising system at Nara,
highlighting anomalous gold zones underneath and directly associated with
surface artisanal gold-producing structures. Kavango will now develop its
understanding of these new zones before testing them with follow-up drilling.

Kavango holds an option to acquire Nara until June 2025 (announced
>>> 26 June 2023
(https://polaris.brighterir.com/public/kavango_resources_plc/news/rns/story/x5zmj9x)
).

Highlights

·    Kavango has now received assay results for six initial scoping holes
recently drilled for a total of 1,364.4 meters ("m") at Nara.

o The assay results confirm five out of six holes succeeded in intersecting
the quartz vein shear structures worked by artisanal miners.

·    Higher gold grades of >5 grams per tonne ("g/t") were returned
from interpreted narrow pinched zones within these structures.

·    The assay results provide confirmation of a gold mineralised system
at Nara and support the potential for a large system of gold-bearing shears at
the project.

·    Higher-grade assays at depth offer compelling evidence for
continuation of structures, along with shallow structures under thick cover
not yet found or worked by artisanal miners.

·    Kavango will now integrate its completed Induced Polarisation ("IP")
surveys and modelled inversions over Nara with its drill data.

o The Company expects the work to identify further drill targets aimed at both
expanding the footprint of existing deposits at the project and testing new
structures.

Ben Turney, Chief Executive of Kavango Resources, commented:

"Our work in Zimbabwe is progressing at such a pace that Kavango's exploration
team is increasingly focussed on exploration for mining.

Our first phase of exploration at the Nara Project confirms the potential for
a large-scale gold-bearing system here. We believe this is shaping up to
become an underground opportunity for Kavango Mining to pursue. We are
encouraged both by the grades we have encountered and widespread gold
mineralisation.

We will now complete our analysis of the data we have gathered to design the
next phase of drilling. We will provide an update on this in the coming weeks
and plan to mobilise a second rig a little later this year."

Progress Overview

The Company's objective was to intersect quartz vein shears underlying
gold-producing artisanal workings and historic underground mine workings.
Artisanal gold production at Nara takes place in narrow surface workings
<0.5m wide along successive structural shear zones hosting anastomosing
quartz veins. Individually worked quartz vein shears characteristically pinch
and swell at depth, with arsenopyrite observed within gold-bearing quartz
veins and altered wall-rock. The artisanal miners often use the presence of
arsenopyrite to guide their development.

The assay results confirm five out of six holes succeeded in intersecting the
quartz vein shear structures worked by artisanal miners. Higher gold grades of
>5 grams per tonne ("g/t") were returned from narrow pinched zones within
these structures. Evidence from the artisanal surface workings suggest there
are, as yet untested, wider zones where the mineralised structures widen.

The assay results provide confirmation of a gold mineralised system at Nara
and support the potential for a large system of gold-bearing shears at the
project. Higher-grade assays at depth offer compelling evidence for
continuation of structures, along with shallow structures under thick cover
not yet found or worked by artisanal miners. Concurrently collected ground
Induced Polarisation ("IP") gradient array surveys in conjunction with stacked
Schlumberger Sections over Nara provides further context for the interpreted
lateral and depth extensions of the gold producing artisanal structures.

Kavango will now integrate its completed IP surveys and modelled inversions
over Nara with its drill data. The Company expects the work to identify
further drill targets associated both with expanding the footprint of existing
deposits at the project and testing new structures.

Results and Interpretation

The Nara Project extends for 3km along the western sheared margin of the
greenstone belt across 2.5km to the eastern boundary (1.1km), with a core
comprised of metavolcanics bordered by banded iron formations, cross-cut by
basic dykes occupying dilational structures.

Kavango's initial drilling focused on old mine workings and abundant artisanal
workings along parallel structural features consisting of anastomosing quartz
veins in shears with sulphides and arsenopyrite.

Six scoping holes were completed, totalling 1,364.4m, to test the gold bearing
potential underneath the old mine workings and artisanal surface workings. All
six holes have been logged, cut and sampled, and sample assays have now been
received. Analysis for gold was by 25g fire assay with AAS finish and carried
out at Performance Laboratories (Pty) Ltd, Harare.

Table 1, below, provides significant results of >0.5g/t Au. All holes were
assayed over their full cored length.

Table 2: List of boreholes

Kavango's initial scope drilling focused on historic mine workings and
abundant artisanal surface workings along parallel structural features
consisting of anastomosing quartz veins shears with sulphides and
arsenopyrite.

Six scoping holes were completed, totalling 1,364.4m to test the gold bearing
potential underneath the old mine workings and artisanal surface workings.

The Kavango technical team interprets these results as significant when
considering the following qualifying factors:

·         The drill intersections appear to reflect the narrower
(<0.5m) portions of the anastomosing quartz vein shears that host the
artisanal gold production with their characteristic pinch and swell
morphology.

·         The sampling of half NQ drill core (47.6mm diameter) is
thought to be indicative rather than representative of the gold bearing
structures given the anastomosing nature of the veins, and the probable nugget
effect.

·         The assay values may under-represent the quartz vein shear
structures as compared with grades reported by artisanal miners from their
production at depth on the same and similar structures, and past production at
the historic mines.

·         The Nara Claims area contains 5 historical gold mines that
were mined between 1904 to the 1960's, with production from 4 of the mines
totalling over 93,000 Oz gold, Table 3.

Figure 1 below, shows the regional geological setting of the Nara Claims
occupying the sheared western and eastern margins of the greenstone belt
bordered by banded iron formations ("BIF"), which form distinct magnetic
features in Figure 2.

blue), backdrop is the geology of the greenstone belt with structural
features, historic mine locations and artisanal surface workings. Kavango's
drill hole collar positions are marked.

The historic mine workings and gold producing artisanal workings can be seen
to overlie mapped structural features or faults and shears interpreted from
both regional and local ground magnetics in conjunction with air photo and
satellite images.

Concurrently collected ground Induced Polarisation ("IP") gradient array
surveys in conjunction with stacked Schlumberger Sections (Figure 3) over Nara
provide context for possible extensions of the gold producing artisanal
structures at depth and along strike. These also provide indications for
further exploration possibilities on other shallow structures that may be
under thicker cover and not found or worked by the artisanal miners.

Next Steps

The completed gradient array IP and modelled inversions will be integrated
with the existing drill data. The combined interpretation is expected to
identify further drill targets targeted at both expanding the footprint of
existing deposits and testing new structures.

A sampling exercise in currently underway to collect a bulk sample from one of
the historic mine workings as well as representative samples from as many of
the gold producing artisanal workings as possible.

In order to assess the wider prospectivity of the area and compare current
artisanal gold production with historic underground mine production, the
assays from this sampling programme will be compared with assays from the
drill programme.

Kavango intends to recommence drilling at Nara, once it has completed this
analysis. The Company will provide a further update in due course.
