What Deep Yellow does

Deep Yellow Limited is a uranium exploration and development company with its flagship Tumas Uranium Project in Namibia. The company is listed on the ASX and the Namibian Stock Exchange under the ticker DYL, with shares also quoted on the OTCQX in the United States. The company describes Tumas as a fully permitted greenfields project in a Tier 1 jurisdiction.

As a development-stage company, Deep Yellow’s reporting focuses on construction progress, funding strategy and project Economics rather than production revenue.

FID target update

In an ASX announcement dated 16 October 2026, Deep Yellow stated that it remains committed to completing construction of Tumas but has determined that current equity market conditions do not support a Final Investment Decision in Q4 2026. The company withdrew its previously announced FID target for that quarter, citing continued subdued equity market conditions that constrain funding Options for uranium developers.

The company said that the expenditure associated with the current civil and concrete works is fully funded with existing cash reserves, which allows further systematic de-risking of the project before FID. It added that it is progressing its funding strategy.

Optimisation work and value case

Deep Yellow stated that optimisation work and an updated value model for Tumas are nearing completion. The work brings together technical and commercial assessments undertaken to strengthen the project’s development and operating strategy. A comprehensive project update will be released once the work is finalised, providing updated economics and the basis for the next stage of development.

Construction progress at Tumas

Civil works commenced on schedule, with two concrete contractors on site and work underway in the Counter Current Decantation (CCD), clarification, leach and beneficiation areas. Contractors have begun placing blinding concrete, carrying out detailed earthworks excavation and fixing reinforcing steel in the CCD area.

The company reported that approximately 170 tonnes of reinforcing steel have been installed, and that all seven CCD centre bosses and one clarifier centre boss have been shuttered and approved for pouring, with pours commencing. Pre-casting of retained earth wall panels remains on schedule.

Contracts, approvals and site activity

Four supporting local Namibian contracts totalling N$42.1 million (A$3.7 million) have been awarded. Environmental Clearance Certificates were renewed by Namibia’s Environmental Commissioner. The company also reported that 440 inductions have been completed for contractors and employees, covering health and safety, environment, radiation and fatality prevention management.

What the updated value case is expected to cover

Deep Yellow has said the optimisation work draws on extensive technical and commercial assessment and will feed an updated value model for Tumas. The company has not published figures from that work in this announcement. The release states that a comprehensive project update will be provided to the market when the work is finalised, setting out the updated economics and the basis for the next stage of development.

The announcement also references pre-casting of retained earth wall panels, concrete mix design test campaigns by contractors and the shuttering of centre bosses as examples of the preparatory work completed ahead of scheduled concrete pours.

Sector context

Uranium developers rely on equity markets, project finance and offtake arrangements, and the timing of investment decisions can be affected by market conditions. During the session the S&P/ASX 200 Energy index was at 11,167.20 and the broader S&P/ASX 200 was at 8,806.90, while Brent crude was at US$109.48 per barrel amid Middle East tensions.

Risks and uncertainties

The Q4 2026 FID target has been withdrawn, and no replacement date has been given in the release. Construction and optimisation work continue before a funding decision, and funding outcomes depend on equity market conditions and the company’s funding strategy. Further risks include project cost and schedule changes, permitting, Commodity price movements, logistics in Namibia and the outcome of the updated value case, which has not yet been published.

Because the Q4 2026 target has been withdrawn without a replacement date, the release does not provide a timetable for the decision, construction completion or first production.

Catalysts to watch

Items referenced in the release include publication of the comprehensive Tumas project update and updated value case, progress on concrete pours and pre-casting, the company’s funding strategy and any new timetable for a Final Investment Decision.

Wrapping up

Deep Yellow’s 16 October 2026 update combined a withdrawn FID target with on-site construction progress and fully funded current works. The forthcoming project update will provide the updated economics referred to in the release.
