Deep Yellow Limited has accelerated progress at its flagship Tumas uranium project in Namibia, awarding major construction contracts and pushing detailed engineering close to 80% completion ahead of a Final Investment Decision expected in Q4 2026. Exploration activities in Namibia and Australia continue to build the company’s resource pipeline amid a strengthening uranium market.
- Tumas Project detailed engineering at 79% completion
- Two major Namibian civil contracts awarded post-quarter
- Acquisition of 50% stake in Cooper Creek JV expands Australian footprint
- Mulga Rock feasibility study optimisation ongoing
- Uranium prices hit record long-term and spot highs
Tumas Project Nears Final Investment Decision with Construction Contracts Awarded
Deep Yellow Limited (ASX:DYL) has taken significant strides towards developing its flagship Tumas Project in Namibia, advancing detailed engineering to 79% completion and completing bulk earthworks during the June quarter. Crucially, shortly after quarter-end, the company awarded two major civil and concrete construction contracts to established Namibian contractors, a move designed to diversify construction fronts, enhance schedule flexibility, and reduce execution risk ahead of a Final Investment Decision (FID) anticipated in Q4 2026.
This contract award not only signals growing construction readiness but also demonstrates Deep Yellow’s commitment to local content and job creation in Namibia. Mobilisation of contractors is scheduled for August 2026, setting the stage for ramped-up onsite activity. Procurement efforts have also gathered pace, with 76% of major process plant equipment tendered and several long-lead packages conditionally awarded pending FID.
Exploration Momentum Builds Across Namibian and Australian Assets
Exploration remains a key pillar of Deep Yellow’s strategy. In Namibia, ground radiometric surveys at the S-Bend Prospect progressed, with drilling set to commence next quarter. Recent drilling at the nearby Tinkas Prospect confirmed uranium mineralisation in both calcretised sediments and basement rocks, refining geological models and expanding regional exploration potential.
In Australia, Deep Yellow strengthened its position in the Alligator Rivers Uranium Province by acquiring a 50% interest in the Cooper Creek Joint Venture from Energy Resources of Australia Limited (ASX:ERA). This acquisition adds approximately 810 km² contiguous to Deep Yellow’s existing tenure, expanding its footprint in one of the world’s premier uranium provinces to about 4,820 km² and reinforcing its exploration pipeline.
Mulga Rock Project Advances Feasibility and Hydrogeological Studies
Progress at the Mulga Rock Project in Western Australia continues with optimisation work on the revised feasibility study. The company is simplifying the processing flowsheet and refining project economics through metallurgical test work and mining method evaluations. An updated geometallurgical model is under development to support improved mine planning and processing performance.
Preparations for a hydrogeological drilling program are underway, aiming to better define pit dewatering requirements. Drilling is scheduled to commence next quarter, with groundwater test pumping planned for the first half of 2027 to inform mine design.
Uranium Market Strength Supports Project Development Strategy
The uranium market continued its upward trajectory, with the average long-term uranium price reaching a record US$95.50 per pound U₃O₈ by 30 June 2026, a 19% increase year-on-year. The spot price also rose to US$85.00 per pound, up 8% over the same period. Long-term contracting activity is recovering, with 33 million pounds contracted in the first half of 2026, signaling growing market confidence.
Notably, Australia and India finalised arrangements enabling long-term uranium exports, opening a strategic market for Australian producers. Deep Yellow’s disciplined approach to project development aligns with these market fundamentals, aiming to deliver long-life, high-quality uranium assets positioned for the next uranium cycle.
Financial Position and Expenditure Reflect Focused Development
Deep Yellow ended the quarter with a strong cash balance of A$160 million, down slightly from A$171.6 million in March 2026, reflecting disciplined expenditure. Development costs of A$11.2 million were primarily directed towards advancing the Tumas Project’s engineering, procurement, mine planning, and early works. Exploration and evaluation expenditure totaled A$2.8 million, supporting resource growth and technical de-risking across the Namibian and Australian portfolios.
Payments to related parties amounted to A$0.3 million, comprising standard director remuneration. The company also issued 139,036 fully paid shares on exercise of performance rights during the quarter.
Bottom Line?
Deep Yellow’s methodical progress on Tumas and strategic exploration expansions position it well to capitalise on a strengthening uranium market, with the upcoming FID and contract mobilisations key milestones to watch.
Questions in the middle?
- Will the Final Investment Decision for Tumas proceed as planned in Q4 2026 amid evolving market conditions?
- How will the newly acquired Cooper Creek JV stake translate into tangible resource growth and exploration success?
- What impact will ongoing uranium price volatility have on Deep Yellow’s project financing and development timelines?
