Highlights
Portable x-ray fluorescence 'pXRF' analysis of 335 previously collected soil samples completed: Encouraging concentrations of zinc identified.
Zinc is a recognised pathfinder element for the less mobile copper ions in the soil.
Elevated levels of zinc in soil samples can be associated with shallow strata-bound copper mineralisation. 127 new soil samples collected, dried and sieved: Soil samples taken in areas of particular interest.
pXRF analysis ongoing.
Interpretation of regional aeromagnetic surveys has identified favourable stratigraphy in anticlines and synclines within the licences:
Anticlines and synclines are types of rock strata fold that respectively form crests and troughs. Where anticlinal folds also vary in slope along the fold axis-strike they can also create stratigraphic 'domes' which can be favourable sites for the formation of orebodies.
Anticlinal 'domes' can bring the mineralisation close to surface and within reach of open pit mining.
Higher concentrations of soil zinc anomalies identified near several anticlines Soil samples have been submitted for TerraLeach assay testing, an analytical method designed to remove the mobile ion component from soil samples with a view to detecting metal dispersion from a buried orebody.
Assay results expected in the New Year.

Of note, both Power Metal and Kavango have a strong working capital position meaning we have the financial means, alongside the operational determination, to push on with proactive exploration through the Strategic Joint Venture.'
Progress at South Ghanzi
Portable XRF analysis ('pXRF') was completed on the 335 soil samples previously collected at South Ghanzi (4 December 2020).
Results from the XRF analysis revealed elevated concentrations of zinc in several key areas.
In parallel to this, Kavango's geophysicists completed reinterpretation work on data gathered from government sponsored regional aeromagnetic surveys. Magnetic data collected by previous exploration companies is also available on 'open source'.
Thanks to the reinterpretation of this data, Kavango's exploration team has identified a number of significant anticlines and synclines that occur close to geochemical reduction-oxidation ('redox') boundaries across the
Anticlinal 'domes' often act as trap sites for high-grade copper/silver deposits across the KCB. Their proximity to surface makes them extremely attractive exploration targets.
Because zinc in soil anomalies occur close to several anticlines, Kavango's exploration team collected an additional 127 new soil samples in those areas.
A selection of these samples has been sent to a laboratory in

STRATEGIC JOINT VENTURE INTERESTS IN THE KALAHARI COPPER BELT
THE SOUTH GHANZI PROJECT GEOLOGICAL SETTING
The redox boundaries were formed several hundred million years ago in active sedimentary basins flooded by shallow seas. Organic matter accumulating on the sea floor created anoxic conditions, which formed a chemical barrier to metal ions rising upwards through the sediments as the basin subsided. The change in chemistry caused the precipitation of metal species (carbonates, sulphides etc.) including copper and silver on or just below the redox boundary.
Subsequent tectonic activity folded the sedimentary layers, which was often accompanied by the concentration of metals into the fold hinges.
Several large-scale copper/silver ore deposits have been discovered on the KCB in association with fold hinges in areas now held under licence by
Accumulations of sulphide metals can be traced along the strike of redox boundaries (sometimes for many kilometres), since they often have a higher magnetic signature than the surrounding rock.
