Deep Yellow Limited has reported progress across its exploration projects in Namibia and Australia during the December 2025 quarter.
In Namibia, Deep Yellow Limited completed a drilling programme at Tumas, west of ML237, targeting a previously unexplored 7 km section.
The programme ran from mid-October to mid-November and included 39 holes covering just over 1 800 metres. Drilling confirmed the presence of the channel and identified sedimentary deposits.
The company said the area showed limited potential for uranium and plans to shift exploration in 2026 to areas with stronger prospects.
The company continues to advance the Tumas uranium project after securing a 20-year mining licence from the Ministry of Mines and Energy in September 2023.
The licence positions Tumas to become Namibia’s fourth uranium mine.
Exploration at Tumas began in 2016 and has focused on uranium-bearing palaeochannels stretching about 125 kilometres.
The project has confirmed a total uranium resource of 137 million pounds, including 79.5 million pounds classified as reserves. About 30% of the system remains unexplored, leaving scope for further discoveries.
The company said discoveries at Tumas 3 and Tumas 1 East led to a fourfold increase in resources at a low discovery cost.
The project is expected to operate for at least 30 years, with potential for a longer mine life.
In 2023, Deep Yellow completed a re-costing study that reviewed construction and operating costs against recent global price and supply chain pressures.
The study confirmed Tumas remains a commercially viable uranium project and supported plans for detailed engineering work and project financing.
In Australia, the company completed its 2025 drilling programme at the Alligator River Project in the Northern Territory.
The work included 10 core holes and nine reverse circulation holes. Results pointed to a large hydrothermal system at the Q14 anomaly, with features similar to known uranium deposits in the area.
The programme also included mapping, soil sampling, airborne surveys and seismic testing.
At the Mulga Rock Project in Western Australia, Deep Yellow completed gravity and seismic surveys in late October as part of ongoing exploration work.
