Deep Yellow Limited’s Quarterly Activities Report: A Deep Dive into Uranium and Critical Minerals

  • Deep Yellow Limited's Quarterly Activities Report showcases advancements in its Tumas and Mulga Rock projects.
  • Tumas project gains include upgraded mineral resources and a reaffirmed commercial viability through feasibility studies.
  • Mulga Rock project exhibits promising results in metallurgical testwork, hinting at increased revenue potential and economic improvements.

Deep Yellow Limited recently released its Quarterly Activities Report for the period ending 31 March 2024. The report unveils significant advancements and promising prospects in its Tumas and Mulga Rock projects, signaling positive trends in the company’s financial outlook.

Tumas Project: Advancing Towards Production The Namibian Ministry of Mines and Energy granted Mining Licence 237 (ML 237) to Deep Yellow, enabling the company to progress towards production at its Tumas project. This milestone positions Tumas as the 4th uranium mine in Namibia, a strategic achievement for Deep Yellow.

Resource Upgrades and Feasibility Studies

Deep Yellow’s Tumas 3 Mineral Resource saw a substantial upgrade to 66.8Mlb at 300ppm eU3O8, with indicated Mineral Resources reaching 60.6Mlb at 325ppm eU3O8. These upgrades, achieved through a comprehensive drill program, reflect a remarkable 11% increase in resources without compromising grade.

The company’s Definitive Feasibility Study (DFS) Re-Costing Study reaffirmed the commercial viability of the Tumas project as a long-term, high-margin operation. Key adjustments, such as raising the base case uranium price to US$75/lb U3O8 and lowering initial capital cost estimates, resulted in a 68% increase in post-tax NPV8 to US$570.0M (A$838.2M) and an IRR of 27.0%.

Financial Metrics and Market Conditions

Deep Yellow’s revised Life of Mine (LOM) C1 operating cost after vanadium credit remained competitive at US$34.36/lb U3O8. Moreover, price scenarios based on market studies suggest a potential post-tax real NPV8 of US$663M (A$975M) at an average uranium price of US$80.71/lb U3O8, further strengthening the financial attractiveness of the project amid favorable market conditions.

Mulga Rock Project: Unlocking Revenue Potential

In tandem with its Tumas advancements, Deep Yellow has made substantial progress at its Mulga Rock Project (MRP). Ongoing metallurgical testwork has yielded highly encouraging results, indicating the potential for increased project revenues through enhanced recovery of uranium and critical minerals.

The company’s focus on improving overall recovery rates for uranium above 90% and critical minerals above 70% underscores its commitment to maximizing resource utilization and economic efficiency. These improvements, compared to previous DFS outcomes, set the stage for an improved economic outcome at the Mulga Rock Project.

Mineral Resource Estimates and Market Impact

Deep Yellow’s delivery of samples for multi-element geochemistry analysis, aimed at updating the Mineral Resource Estimate (MRE), aligns with market demand for both uranium and critical minerals. Anticipated results in Q1 2024 will provide stakeholders with valuable insights into the project’s resource potential and market competitiveness.

Financial Implications and Investment Outlook

The positive trajectory showcased in Deep Yellow’s quarterly report bodes well for investors and industry stakeholders. The company’s robust financial metrics, validated by comprehensive feasibility studies and market-responsive strategies, position it favorably in a dynamic market landscape.


Deep Yellow Limited’s Quarterly Activities Report highlights a strategic approach towards sustainable growth and value creation. With significant resource upgrades, improved financial metrics, and ongoing advancements in project development, Deep Yellow solidifies its position as a key player in the uranium and critical minerals sector. Investors and industry observers can look forward to continued progress and value accretion as the company navigates towards its long-term objectives.
