KAVANGO RESOURCES PLC
("Kavango" or "the Company")
Ditau i10 update
Kavango confirm the completion of the first diamond drill hole at the Ditau Camp Project, Botswana, hole DITDD003 (the "Borehole").
The hole was completed to a total depth of 300.14m, which the Company's technical team believes has tested the geophysical target at this specific location.
The Borehole intersected units including a breccia of 20.44m from 83.90m, and a dolomitic carbonate rock from 154.89m. This latter may contain stromatolitic features. Kavango's technical team is now assessing the provenance of the breccia unit, which it believes may represent either a weathered carbonatitic ash flow or a weathered Dwyka tillite.
In addition, a 7.16m intrusive, considered to be a dolerite, was intersected from 247.73m.
While the provenance of the breccia unit is uncertain the Company has performed some initial portable X-Ray Fluorescence ("pXRF") readings on the matrix and larger clasts, with a view to comparing these with both carbonatitic ash flow and also unweathered Dwyka tillite. The Company has access to recently drilled Dwyka tillite in the region and will use this data to as a comparison against readings from the breccia in the pXRF checks. Subsequent to this core from DITDD003 will be cut and sent to an accredited laboratory for whole rock analysis with petrological work also carried out on selected samples.
Hole DITDD003 is one of six planned boreholes in the current programme. The drill rig is currently being moved to the pad for the next hole in the campaign, DITDD004.
The POW/KAV Joint Venture at Ditau
Ditau is held in a 50/50 Joint Venture ("Kanye Resources") with Power Metal Resources plc (LSE:POW) ("Power Metal"). Kavango is the operator. Mindea Exploration and Drilling Services (Pty) ("Mindea") is conducting the drilling.

NOTES TO EDITORS
THE DITAU CAMP PROJECT
The Ditau Camp Project comprises two Prospecting Licences ("PLs") (PL169/2012 & PL010/2019) that cover an area of 1,386km2. Geophysical and geochemical analyses by Kavango in the two PLs have identified 12 "geophysical structures" of which 9 have clear indications of being "ring structures".
The "ring structures" have the potential to host carbonatite and other intrusive rocks.
Carbonatites are the principal source of rare earth elements ("REEs") including the much sought-after elements Neodymium (Nd) and Praseodymium (Pr), which are used in the manufacture of the new generation of electric vehicles (EVs), magnets and other high-tech applications. Other elements/minerals associated with carbonatites include Niobium, Phosphates, Monazite, Strontium, Magnetite and Copper.
Meanwhile, mafic intrusives have potential to host base and precious metals, as seen in the Molopo Farms Project, Selebi Phikwe and Tati Nickel deposits in Botswana.
DITAU REGIONAL GEOLOGICAL SETTING
Carbonatites often occur in "swarms" or clusters, oriented along favourable and clearly defined deep continental scale geological, structural trends. The 12 Ditau geophysical structures occur along a southwest-northeast regional corridor, along the south-eastern edge of trend that hosts the Mabuasehube and Kokong kimberlite groups. Desktop analysis of regional data by Kavango's geologists suggests this trend is parallel to other corridors that host other kimberlite groups in Botswana and northwest Angola. In the latter these trends are known to host both kimberlite and carbonatite intrusives, so they are really indicators of each other.
In addition to the known presence of kimberlites within the "Ditau trend" (in numerous published reports and maps), and supporting the possible presence of carbonatites, are an as yet small cluster of carbonatite intrusives (KW2, definite, and KS12 & KS36 possible bodies) in the vicinity of the project (the "Falconbridge Carbonatites"). The Falconbridge Carbonatites were drilled by Falconbridge Exploration Botswana (Pty) Ltd in the late 1970's-early 1980's, to the immediate north and 30km along strike to the northeast of the Ditau project.
GLOSSARY
Breccia: Breccia is a rock composed of rock fragments held together by cement or a fine-grained matrix. The fragments are angular/rubbly in appearance.
Dwyka tillite: Tillite is formed from the consolidation of glacial sediments into a rock unit. The Dwyka tillite is a stratigraphic unit of such a rock, found in southern Africa.
Stromatolite/stromatolitic: Stromatolites are layered sedimentary units that are the result of microbial organisms forming organo-sedimentary carbonate accumulations. These may occur as mats or as masses.
