Deep Yellow has executed a transmission power supply agreement with NamPower and advanced early works at its Tumas uranium project, as the company continues to derisk the project ahead of a final investment decision.
Under the agreement, Tumas will be connected to Namibia’s regional grid via a dedicated 22 kilometre, 220 kV power line, which Deep Yellow will design and construct before handing it over to NamPower after commissioning. The agreement is subject to a final investment decision.
Power supply will be supplemented by an on-site solar facility to be developed under a build, own, operate and transfer arrangement. The solar plant is designed to supply at least 30 percent of the project’s total electricity requirements and up to the full daytime load, reducing exposure to peak grid tariffs. Negotiations with a preferred solar supplier are ongoing.
Water supply planning has also advanced. Fresh water for Tumas will be sourced from the Swakopmund Reservoir via a 65 kilometre pipeline with a capacity of 2.5 gigalitres per year. Draft water supply and development agreements have been received from NamWater, and tenders for the pipeline design and construction have already been submitted.
Project engineering is now more than 60 percent complete, with over 70 percent of major process plant equipment tendered. Bulk earthworks began in October and are 24 percent complete, with completion targeted for March 2026. Temporary construction facilities are already in place.
On financing, an independent technical expert has completed environmental and social due diligence for Nedbank, the project’s mandated lead arranger, allowing the debt financing process to move into documentation.
Deep Yellow said the work completed positions Tumas to move quickly into construction once market conditions support a final investment decision.
