Uranium developer Deep Yellow Limited has completed a 133-hole drilling campaign at its Tinkas Prospect in Namibia, confirming uranium mineralisation and extending exploration potential around its flagship Tumas Project.
Tinkas is an early-stage but strategically important satellite prospect within Deep Yellow’s Namibian uranium portfolio.
It is part of a regional exploration pipeline feeding into Tumas, which is Deep Yellow’s main development asset.
The reverse circulation drilling programme, conducted between 18 February and 18 March 2026, covered 1,363 metres across the Tinkas area, located about 8 kilometres north-west of Tumas, which is currently being prepared for development.
Results from the campaign show consistent uranium mineralisation, with 38 drill holes returning grades above 100 parts per million equivalent uranium (eU₃O₈).
Key intersections include 11 metres at 265 ppm eU₃O₈ from 2 metres in hole TUBR1296, and 4 metres at 244 ppm eU₃O₈ from 3 metres in hole TUBR1335.
The company said the drilling confirmed uranium mineralisation hosted in calcretised palaeochannel sediments and in fractures within the underlying basement rocks, reinforcing the broader prospectivity of the Tumas region.
The Tinkas Prospect forms part of a wider exploration footprint around Tumas, one of Namibia’s most advanced undeveloped uranium projects, and the results are expected to guide further work aimed at defining a maiden resource.
Deep Yellow indicated that additional infill drilling may be required to establish a resource at Tinkas, suggesting the prospect remains at an early yet promising stage of development.
