Botswana is one of Africa’s richly mineral endowed countries and its borders are uniquely positioned over the continent allowing explorers access to a diverse range of mineral domains and mineralisation systems. These include systems such as iron-oxide copper gold (IOCG) deposits from the Lufilian Arc in the northwest; granite related gold and mafic related nickel-copper-PGE deposits in the Rhodesian Craton and Limpopo Mobile Belt to the east; Bushveld style mineralisation from large igneous provinces in the south; stratiform copper in the Damaran Mobile Belt to the north; and younger kimberlite intrusives which host diamonds in central Botswana.
Botswana is considered relatively underexplored compared with some African countries and other continents around the world. With sound governance and permitting systems, along with encouragement towards activities by junior / small explorers, Botswana holds a lot of potential for mineral exploration success.
The excellent availability of digital geological, geochemical and geophysical data makes Botswana an ideal region for GIS-based prospectivity modelling. Prospectivity modelling over Botswana, Namibia and Zambia for IOCG mineralisation was completed by Kenex in 2011 to upgrade our existing model over Namibia and Zambia and to include newly available digital data over Botswana. At the same time we completed models for sediment-hosted Cu mineralisation over all three countries. This modelling was undertaken on a continental scale and will be ideal for explorers who are looking at areas for prospecting IOCG and sediment-hosted Cu mineralisation.
Kenex has completed prospectivity models for these mineralisation styles for Discovery Metals Ltd.
Opportunities exist to complete detailed prospectivity models over the east of Botswana. This could include models for orogenic gold mineralisation within the greenstone belts of the Zimbabwe Craton and for mafic associated nickel-copper-PGE mineralisation in the Limpopo Mobile Belt. Kenex would utilise newly acquired digital geology and detailed geophysical and geochemical data to create models which identify the best exploration targets in North-East Botswana.
Galane Gold who is operating the Mupane Gold Mine in the Tati Greestone Belt in North-East Botswana and hold an extensive exploration tenement package in the area is one such company making use of Kenex prospectivity modelling.
