Uranium mineralization is largely constrained within Karoo palaeochannels that are up to 60mt deep from surface. These two prospects are about 120km to the south west of, and along strike from, the Karoo rocks that host the uranium resource at the large Letlhakane deposit (owned by A-Cap Resources) and Impact’s first uranium discovery in Botswana at Lekobolo.
The Mosolotsane Prospect is located about 50km north west of the town of Mahalapye. Here the RC drill program comprised 35 holes for a total of 830mt drilled on six sections that are from 200mt to 400mt apart, with holes at 100mt intervals along the sections.
The drill holes have defined an east-west striking Karoo mineralized palaeochannel that extends for about 1,800mt of strike and is up to 600mt wide, and that is open to the east and west.
The Karoo sedimentary rocks lie on a granitic basement which is strongly altered by haematite and clays, and in most of the holes which penetrated this granite basement there are thick intercepts of modest uranium grade, such as 51mt at 60ppm eU3O8 from 1mt depth. The exploration significance of these results is being assessed.
The Morolane Prospect (formerly the Kodibeleng North Prospect) is about 12km west south west of the Mosolotsane Prospect. Here the maiden drill program comprised 71 RC holes for a total of 3,604mt at a broad drill hole spacing of between 500mt by 500mt and 500mt by 200mt in some places. All the holes have been surveyed by down-hole gamma probe and the data for the first 49 holes has been processed.
