London-listed Kavango Resources has announced preliminary interpretation results for geophysical survey data on its property in Botswana’s Kalahari Copper Belt (KCB) from South Africa-based New Resolution Geophysics, with basin margins along the KCB considered prospective sites for copper and silver mineralisation.
Preliminary interpretation of magnetic data from this survey combined with re-processed regional magnetic data and satellite images, clearly define fold hinge targets in the D'Kar Formation (DKF) that correlate with preliminary AEM targets.
Fold hinges are associated with mineralisation elsewhere on the KCB, such as at ASX-listed Sandfire Resources’ Motheo mine, Kavango points out.
The updated geological interpretation is supported by recent regional mapping traverses that identified subcropping units within the lower DKF, the target stratigraphic unit for mineralisation, Kavango notes.
Historic drilling by ENRG, from whom Kavango in 2023 acquired a 90% interest in six licences, confirms the existence of lower DKF in the fold structures recently mapped and noted pathfinder minerals pyrite, sphalerite and galena.
“Based on its analysis of regional copper/silver deposits in the KCB, Kavango believes the configuration of basin and sub-basin structures, including basin margins and intra-basinal highs, plays a pivotal role in many sedimentary copper models.
“We’re quietly confident our KCB exploration programme is going to deliver,” CEO Ben Turney says.
“The different exploration data sets we’ve gathered appear to point in the same direction, namely that our ground covers the style of large-scale system that could host significant copper/silver deposits.
“We are now defining final target areas to test with ground geophysics and then drilling a little later this quarter,” he adds.
