Latest Development: Final Investment Decision Update for Tumas

In its 16 October 2026 announcement, Deep Yellow said it remains committed to completing construction of Tumas but has determined that current equity market conditions do not support a Final Investment Decision (FID) in Q4 2026. The company described the withdrawal of the FID target as a prudent decision given continued weak equity market conditions.

According to the release, expenditure on the current civils and concrete works is fully funded from existing cash reserves and allows further systematic de-risking before FID. Managing Director and CEO Greg Field said challenging equity market conditions continue to constrain funding options for uranium developers, and that the company is maintaining construction momentum while progressing its funding strategy.

The company also stated that optimisation work and an updated value model for Tumas are nearing completion. A comprehensive project update will be released once that work is finished.

Latest Development: Civil Works and Construction Progress

The company reported that civil works commenced on schedule, with two concrete contractors established on site and working in the Counter Current Decantation (CCD), clarification, leach and beneficiation areas.

Approximately 170 tonnes of reinforcing steel have been installed.
All seven CCD and one clarifier centre bosses have been shuttered and approved for concrete pouring, with pours having commenced.
Blinding concrete has been placed for six leach tank and two cold leach feed tank ring beams.
Excavation for the run-of-mine bin is complete, and pre-casting of retained earth wall panels in Swakopmund is on schedule, with 26% of panels cast.
Two commissioned concrete batching plants are on site, supported by a 200,000-litre water storage system.

Latest Development: Local Contracts, Approvals and Safety

Four enabling contracts with a combined value of N$42.1M (A$3.7M) were awarded to Namibian businesses, covering fuel, raw water, waste management and dust suppression services for construction.

Namibia's Environmental Commissioner approved renewal of the Environmental Clearance Certificates for the Tumas Project Area, powerline and water pipeline on 2 October 2026. The project area and water pipeline certificates are valid to 26 September 2029, and the powerline certificate to 27 September 2029. Updated Environmental Management Plans will apply throughout construction, development and operation.

The company also reported that 440 contractors and employees have completed inductions covering health and safety, environment, radiation and fatality prevention management.

Risks and Catalysts on Watch

The release identifies the following items:

The Q4 2026 FID target has been withdrawn, and the release does not give a replacement date.
The company has stated that it is progressing its funding strategy so that Tumas is positioned to advance when market conditions improve.
A comprehensive project update with updated economics is to be released once optimisation work is complete.
Completion of all six leach tank ring beams is targeted before the end of December 2026.
The forward-looking statements section lists permitting, commodity prices, labour and materials shortages, inflation, availability of capital and financing, and Middle East geopolitical risks as factors that could affect outcomes.

Wrapping Up

The 16 October 2026 update from Deep Yellow combined the withdrawal of the Q4 2026 FID target with a report of ongoing civil works, new local contracts and renewed environmental approvals at Tumas. The company said it will publish a comprehensive project update once its optimisation work is complete.
