Deep Yellow Limited has reported promising outcomes from its recent drilling operations at the S-Bend prospect in Namibia, unveiling new zones of uranium mineralisation that may significantly bolster its existing resource inventory and extend the operational lifespan of its cornerstone Tumas Project.
The company undertook a comprehensive reverse-circulation (RC) drilling campaign from July through September 2025, completing a total of 452 drill holes that together covered 3,361 metres. The drilling was carried out within Exclusive Prospecting Licence (EPL) 3497, a highly prospective area that lies immediately adjacent to the Tumas Project in Namibia’s Erongo Region.
The results revealed that approximately one-third of the drill holes intersected uranium mineralisation, with concentrations exceeding 100 parts per million (ppm) of triuranium octoxide (U₃O₈) — a significant threshold in uranium exploration.
Importantly, the uranium was not only discovered within the Tertiary-age sedimentary layers, which are typically the primary hosts for surficial uranium deposits in the region, but also in the underlying Proterozoic bedrock. This older geological formation was found to be fractured and/or foliated, conditions which can facilitate the deposition of uranium and suggest the potential for deeper, structurally controlled mineralisation.

According to Deep Yellow, these intersections indicate the potential to uncover additional uranium resources beyond those currently defined at Tumas. If confirmed through further drilling and evaluation, the S-Bend discovery could play a critical role in expanding the overall resource base and potentially lengthening the life-of-mine for the Tumas uranium project — a key development for the company’s long-term strategic growth in the uranium sector.
