Kavango Resources PLC (LSE:KAV, OTC:KVGOF) has completed the relogging of drillhole DITDD004 at the Ditau project in Botswana.
The hole was relogged on the recommendations of Dr Hamid Mumin who recently suggested the presence of a possible banded iron formation-hosted lode gold system at Ditau.
Hole DITDD004 was drilled to test the i10 Target.
The relogging highlights that the previously reported gold assays occur with the presence of fine pyrite in the BIF.
The association of pyrite with the gold, typical in gold deposits, is useful confirmation of some of the characteristics of the Ditau mineralisation. These characteristics will then be targeted in the next stage of exploration.
Kavango is developing a working hypothesis that some of the sediments above the BIF may be of Proterozoic age, rather than of the much younger Karoo age sediments.
If this is the case, then mineralising fluid flow could also have taken place through these.
Proterozoic age BIFs, such as at Ditau, can be associated with lode gold systems.
"Dr Hamid Mumin's report has highlighted the gold potential at Ditau and proposed a new deposit model,” said Brett Grist, chief operations officer of Kavango.
“Relogging of the core by Kavango has identified a number of features that could be consistent with this. We look forward to logging the additional drillholes we've identified over the I10 Target at the end of this month and using the results to expand our exploration program."
Additional core samples have been taken and will be sent to a laboratory in Canada for additional assays.
Up to 24 samples are also being sampled for petrological work under the supervision of Dr Mumin, with the aimed of further enhancing Kavango's understanding of the mineralisation style prior to future drilling.
Kavango is now preparing a geophysical survey program at Ditau, which is likely to include induced polarisation surveys targeting pyrite as a proxy for gold.
This will initially be run over already identified mineralisation, to trace the wider extension over the i10 Target area.
Kavango has also been given permission to relog two additional diamond drill holes located over the i10 Target area, which were drilled by another company.
