Deep Yellow Ltd (ASX:DYL; NSX: DYL; OTCQX: DYLLF) is a uranium developer whose flagship asset is the Tumas Uranium Project in Namibia. On 19 October 2026, the shares closed at $0.77, down 6.10%. In an ASX announcement dated 16 October 2026, the company updated shareholders on Tumas, including a change to its target for a final investment decision (FID).

FID update

Deep Yellow says it remains committed to completing construction of Tumas but has determined that current equity market conditions do not support an FID in the fourth quarter of 2026, and it has withdrawn that target. The company says expenditure on the current civils and concrete works is fully funded from existing cash and allows further systematic de-risking before FID. Tumas optimisation work and an updated value case are nearing completion and will be released in a comprehensive project update.

The announcement says constrained equity market conditions continue to limit funding Options for uranium developers and that the company is maintaining construction momentum while progressing its funding strategy so Tumas is positioned to advance when conditions improve.

Construction progress

Civil works started on schedule, with two concrete contractors on site working in the counter current decantation (CCD), clarification, leach and beneficiation areas. About 170 tonnes of reinforcing steel have been installed. All seven CCD and one clarifier centre bosses have been shuttered and approved for concrete, and pours have started. Pre-casting of retained earth wall panels is on schedule.

Four local Namibian contracts totalling N$42.1 million (A$3.7 million) have been awarded, environmental clearance certificates have been renewed, and 440 inductions have been completed covering health, safety, environment, radiation and fatality prevention.

Deep Yellow describes Tumas as a fully permitted uranium project in a tier-one Jurisdiction and says the optimisation work and updated value case are nearing completion. Until those are published, the Economics referred to in earlier announcements remain the reference point, and the company has said it will release a comprehensive project update once finalised.

The announcement shows the construction scope under way: concrete pours in the CCD and clarifier areas, reinforcing steel installation, pre-casting of retained earth wall panels and local contracting. The company says this work allows further disciplined de-risking before FID and that its funding strategy continues to progress alongside construction.

Sector backdrop

The benchmark index finished the session higher. The S&P/ASX 200 (ASX: XJO) stood at 8,845.70 at 4:25 pm (GMT+11) on 19 October 2026, up 0.44%, or 39.00 points, for the day. On the sector map, Energy rose 2.16%, the largest gain among the labelled segments.

Risks shareholders should weigh

The company has withdrawn its FID target, so there is no date for the decision, and it links the timing to equity market conditions that it cannot control. Funding for the full project is not yet in place, and the announcement says the funding strategy is still being progressed.

Construction is continuing ahead of an FID using existing cash, which reduces cash balances before the project is fully financed. The updated value case has not yet been released, so shareholders do not have the revised project numbers. Uranium price movements and Namibian operating conditions also apply.

What’s next

Deep Yellow will complete its optimisation work and release a comprehensive project update with the updated value case, continue civil works at Tumas and progress its funding strategy.
