Deep Yellow Limited has reported encouraging exploration results from its newly identified Tinkas prospect in the Erongo Region, where drilling has revealed uranium mineralisation extending up to 11 metres in thickness.
According to the company, the prospect lies within Exclusive Prospecting Licence 3496, adjacent to Deep Yellow’s flagship Tumas Project on Mining Licence 237.
The area was tested through a 105-hole reverse circulation (RC) drilling programme totalling 1,137 metres, targeting a radiometric anomaly linked to palaeochannels identified through airborne surveys.
In a report released by the company, Deep Yellow said the drilling campaign delivered encouraging results.
“Drilling completed at the new Tinkas prospect returned positive results, with surficial uranium mineralisation observed at surface and continuing at depth,” the company said.
The report noted that 28 of the 105 drill holes intersected uranium mineralisation with a minimum grade of 100 parts per million (ppm) equivalent uranium oxide (eU₃O₈).
The average grade recorded was 260 ppm eU₃O₈, with some of the best intersections including 11 metres at 777 ppm from one metre depth (hole TUBR1179), six metres at 188 ppm and two metres at 1,273 ppm from 11 metres (hole TUBR1180), and nine metres at 149 ppm from two metres (hole TUBR1242).
Deep Yellow said the results confirm the presence of a shallow palaeochannel system filled with calcretised sediments, which are known to host uranium deposits.
The company added that while the exploration target is relatively small, it could still contribute to resource growth at the Tumas Project.
“Based on the current extent of the area, as well as the average thickness and grade of the mineralisation encountered, the exploration target for the Tinkas prospect is considered to be small, although it potentially can add to the current resource base at the Tumas Project,” the company said.
