KAVANGO RESOURCES PLC
("Kavango" or "the Company")
PHASE 2 AIRBORNE ELECTROMAGNETIC SURVEY COMPLETED
Kavango Resources plc (LSE: KAV), the exploration group listed
on the Standard List segment of the main market of the London Stock
Exchange and targeting the discovery of world class mineral
deposits in Botswana, is pleased to announce that Phase 2 of its
airborne electromagnetic (AEM) survey carried out by SkyTEM over
the northern section of the Company's Prospecting Licences that
cover much of the Kalahari Suture Zone (KSZ) structure in southwest
Botswana, has been completed.
HIGHLIGHTS:
AEM Survey
-- The SkyTEM AEM survey covered approximately 2,100 line-kms to
the north of Hukuntsi in southwest Botswana, over Prospecting
Licences PL163/2012, PL365/2018, part of PL364/2018 and single
lines in PL509/2014 and PL510/2014;
-- The SkyTEM AEM survey helicopter and crew have recently demobilized;
-- Preliminary results indicate that SkyTEM's innovative new
generation 312 HP (High Power) technology has achieved exceptional
depth of investigation beneath the Kalahari sand cover and Karoo
sediments due to the high moment (HM) mode with high current and
low base frequency of 12.5 Hz. This system has been on the market
since 2017 and therefore represents a major advance in AEM
systems;
-- The SkyTEM AEM data is currently being interpreted and
modelled by our duly appointed external Consultants, Aarhus
Geophysics in Denmark, in conjunction with SkyTEM;
-- Results of the interpretation, with priority targets for
ground follow-up and drilling, will be announced when they become
available.
Michael Foster, Chief Executive Officer of Kavango Resources,
commented:
"We are pleased to announce the successful conclusion of
SkyTEM's AEM survey covering the northern part of KSZ project area.
The KSZ project covers over 9,000 km(2) of prospective ground for
the discovery of base metal deposits in southwest Botswana. The
Company has now covered approximately 50% of the KSZ licence area
with airborne geophysics. The key now is for a thorough ground
follow up plus of course drilling of further priority targets over
the coming months".

Notes for Editors:
Kavango's 100% subsidiary in Botswana, Kavango Minerals (Pty)
Ltd, is the holder of 15 prospecting licences covering 9,231 km(2)
of ground, including most of the 450km long KSZ magnetic anomaly in
the southwest of the country along which Kavango is exploring for
Cu-Ni-PGE rich sulphide orebodies. This large area, which is
entirely covered by Cretaceous and post-Cretaceous Kalahari
sediments, has not previously been explored using modern
techniques.
The area covered by Kavango's KSZ licences displays a geological
setting with distinct similarities to that hosting the World Class
Norilsk Ni-Cu-PGE orebodies in Siberia.
Exploration Model:
Kavango's exploration model is based upon the search for
magmatic massive sulphide orebodies buried beneath up to 200m of
overburden. The identification of drill targets follows a carefully
constructed exploration program specifically developed by the
Company for exploration in areas covered by Kalahari and Karoo
sediments and sands.
The exploration program is initiated by identifying the location
of magmatic intrusive rocks from an analysis of the regional
magnetic surveys published by the Botswana Government. This is
followed by an airborne electro-magnetic survey (AEM) carried out
over the magnetic anomalies that have signatures indicating the
presence of intrusive rocks at depth. By using the latest
generation of low frequency helicopter-borne EM, conductors lying
below the Kalahari/Karoo cover can be identified for further
investigation. These conductors can be tested on surface by very
high sensitivity soil sampling*, which can detect metal ions
transported from buried, metal rich massive sulphide deposits
associated with the emplacement of magmatic intrusive rocks.
Kavango uses a ground based geophysical technique known as
Controlled Source Audio frequency Magneto Tellurics (CSAMT)** to
identify the exact location of the conductors. The shape,
orientation and depth of the conductors will determine if the
conductor should be drilled. The presence of a metal in soil
anomaly is also used to prioritise the conductors.
The next phase of the exploration involves the drilling of the
conductor to determine the presence of sulphide mineralisation and
its metal component (discovery). This is followed by the evaluation
of the discovery, which will determine whether the deposit is large
enough and rich enough to make an economically viable mine
(feasibility).
*Kavango geologists have pioneered a high resolution soil
sampling technique to detect ultra-fine metal particles which have
been transported in solution from considerable depths of burial to
the surface by capillary action and transpiration. Evaporation
leaves the metal ions as accumulations within a surface "duricrust"
which is then sampled and analysed. Zinc, which is the most mobile
of the base metal elements (i.e. goes into solution easily) acts as
a pathfinder to mineralization at depth.
**Massive sulphide (base metal) deposits can be detected by
CSAMT because they conduct electricity easily (conductors) as
opposed to silicate wall rocks (resistive).
