Aura Energy Limited (ASX: AEE, AIM: AURA) (“Aura” or “the Company”) is pleased to present the updated production target improves economics at Tiris Uranium Project.
KEY POINTS:
- The February 2024 Front End Engineering Design (“FEED”)1 study production target and economics has been updated using the recently expanded 91.3Mlbs U3O8 Mineral Resource2 at the Tiris Uranium Project in Mauritania
- Production Target Update increased the total Project U3O8 life of mine production by 44% to 43.5Mlbs U3O8 and extended the mine life from 17 years to 25 years
- Project economics have also significantly improved:
- NPV8% of US$499 million (A$734 million) an increase of 29%
- IRR of 39% post tax and payback only 2.25 years
- Life of Mine post tax cash flows of US$1,509 million an increase of 42%
Aura’s Managing Director and CEO, Andrew Grove commented:
"The updated economics from the Production Target Update clearly show the very significant value inherent at Tiris as Aura Energy rapidly progress towards the funding and development of the Project. The US$4.5 million drilling program undertaken earlier this year not only delivered a 55% increase In Mineral Resources3 but has also demonstrated over US$100 million of additional Project NPV, now standing at US$499 million. It is our strong belief that there is still very significant potential to continue to add to the Mineral Resource and Reserve inventory around Tiris East and across the whole northern Mauritanian region, within the 13,000km2 of tenements that Aura has under application4.
With the current large scale of the Mineral Resource Estimate inventory and future resource growth potential, the prospect for significant increase in the uranium production rate from Tiris once in production is very real and we are working on assessing, analysing and shortly presenting the results from the work currently being undertaken.
The updated Production Target study has not only increased the mine life and significantly improved the project economics but has simplified and de-risked the early mining sequence and brought forward some uranium production by 21% in the first year, and by 9% over the first five years compared to the FEED study5. These improved metrics will further support the funding process which is currently underway with indicative offers due this quarter.
The Company is rapidly working towards achieving the Final Investment Decision by the end of the current quarter with many activities underway including water drilling, engagement with EPCM contractors and operational readiness preparations. And we look forward to providing further updates on progress.”
Key highlights and outcomes of the updated Production Target:
The update to the production target for the FEED study5 has allowed revenue to be moved forward in the mining schedule and also increased the overall life of mine.
- Robust base case project financial economics demonstrated by post-tax NPV8 of US$499M (A$734M) with IRR of 39%, and a 2.25-year payback at realised uranium price of US$80/lb U3O8
- At uranium prices of US$100/lb U3O8 the economics increase to post-tax NPV8 of US$779M (A$1,145M) with IRR of 55%
- Initial mine life increased from 17 years to 25 years, producing an average 1.8Mlbspa U3O8 from the 2.0Mlbspa U3O8 capacity process plant
- Life of Mine (“LOM”) uranium production increased from 30.1Mlbs U3O8 to 43.5Mlbs U3O8
- 93% Measured and Indicated Mineral Resources in mining schedule during the first four years, LOM Inferred material totals 33% mostly beyond ten years in the mining schedule
- The open pit mining is a simple, low-risk, shallow, free digging operation without the need for crushing and grinding
- Beneficiation delivers a high-grade leach feed averaging 2,217ppm U3O8 increasing from 1,997ppm U3O8 (over first 5 years) and overall remains approximately the same at 1,752ppm U3O8 from 1,743ppm U3O8 (LOM) at a very low average cost of US$9.16/lb U3O8
- AISC has increased to US$35.7/lb U3O8, an escalation of 3% on the 2024 FEED estimate5, largely due to a minor increase in waste to ore strip ratio from 0.7 to 0.8 waste to ore tonnes
- CAPEX of US$230M, was not re-evaluated in this update and remained unchanged from the FEED study7
- Uranium production planned within 18 months of Final Investment Decision
- Modular design provides opportunities for further capital efficient expansion and scalability
- The construction and operation of the Tiris Uranium Project will deliver significant and ongoing benefits to the people of Mauritania
Modular design provides opportunities for further capital efficient expansion and scalability
The update to the Production Target based on the successful exploration drilling program to update the Mineral Resource Estimate6 confirms the value in continued growth of the Tiris Project. The modular circuit design shown in Figure 1 allows flexibility in production scheduling and potential for rapid and simple expansion of production capacity.

Key Projects
Cloncurry Gold Project (Queensland, Australia)
In November 2024, AuKing Mining entered into an earn-in agreement with Orion Resources for the Cloncurry gold project in northern Queensland. This agreement allows AuKing to increase its stake in the project to 50 percent by investing AU$5 million in project funding by June 2027.

A key component of this project is the Tick Hill Gold Joint Venture, involving AuKing, Orion Resources, and Tick Hill Mining, the current owner of the Tick Hill gold mine. The JV aims to establish a processing operation at Tick Hill, focusing initially on reprocessing the existing tailings stockpiles. A pre-feasibility study completed in 2020 outlined a processing capacity of 474,200 tonnes at 2 g/t gold over 13 months, yielding approximately 27,300 ounces of gold at an all-in sustaining cost (AISC) of AU$1,493 per ounce.
In March 2025, the JV partners signed a memorandum of understanding (MoU) to assess the viability of processing Tick Hill's tailings and other ore materials at the Lorena processing plant, located 15 km east of Cloncurry. This initiative aims to expedite the re-commencement of gold production in the region.
The JV also plans to evaluate the feasibility of reopening the historical open pit mine at Tick Hill, with the goal of extending the project's life and enhancing gold production. An independent preliminary economic assessment has concluded that the proposed tailings retreatment plan is both technically and financially viable, recommending progression to a final feasibility study.
Through these strategic initiatives, AuKing Mining is actively advancing the Cloncurry gold project, aiming to unlock significant value and establish a sustainable gold production operation in the Cloncurry region.

The Mt Freda Mining Complex is a key element in the proposed restart of mining operations at the Cloncurry Gold Project in northern Queensland. A comprehensive drilling program, consisting of an estimated 10,000 meters of combined diamond and reverse circulation (RC) drilling, is planned at Mt Freda to support the project’s development.
Myoff Creek
The Myoff Creek project, located in southeastern British Columbia, is a 100 percent-owned niobium and REE exploration asset held by AuKing Mining. It covers approximately 800 hectares across eight mineral claims. Historical work identified significant near-surface carbonatite mineralization spanning about 1.4 km by 0.4 km, with impressive intercepts of 0.93 percent niobium (Nb) and 2.06 percent total rare earth oxides (TREO). The zone remains open both at depth and laterally, and elevated niobium and cerium have been detected in rock chips nearly 2 km from the known mineralization, hinting at substantial upside. Positioned within a well-known mining region and easily accessible via established roads, the project is now primed for modern exploration, starting with a helicopter-borne aeromagnetic and radiometric survey to pinpoint new targets for drilling.
Project Highlights
- Full Ownership: AuKing holds a 100 percent stake in the Myoff Creek project—covering ~800 hectares across eight contiguous claims.
- Strong Historical Mineralization: Near-surface carbonatite zone (~1.4 km × 0.4 km) with high-grade intercepts: 0.93 percent Nb and 2.06 percent TREO.
- Open Mineralization: Zones remain open at depth and along strike; rock chips ~2 km from drilled area show elevated Nb and Ce.
- Strategic Location: Situated in a mining-friendly region, close to major operations like Highland Valley and Copper Mountain Mines
- Good Access: The site benefits from well-maintained infrastructure and road networks
- Current Exploration Underway: A helicopter-borne aeromagnetic and radiometric survey (covering 70 line-km over the tenure, potentially expanding to 7 km strike) is planned to define new drill targets
- High Potential Upside: Thick, low-impurity carbonatites (up to 200 m thick) in a critical mineral belt provide a compelling foundation for resource expansion
Halls Creek Project (Koongie Park Copper-Zinc Project - Western Australia)
The Halls Creek project, also known as the Koongie Park Project, is located 25 km southwest of Halls Creek in Western Australia’s highly mineralized Halls Creek Mobile Belt. It hosts three significant deposits—Onedin, Sandiego, and Emull—with established resources in copper, zinc, gold, silver, and lead. Backed by a 2025 earn-in agreement with Cobalt Blue (ASX:COB), which can acquire up to 75 percent of the project, Halls Creek offers strong development economics, value-engineering upside, and exploration growth potential in one of Australia’s most prospective mining regions.
Project Highlights
- Strategic location in WA’s Halls Creek Mobile Belt, near Savannah, Copernicus and Nicolsons operations.
- Key Deposits:
- Onedin – 4.8 Mt Cu-Zn-Au-Ag-Pb resource; silver credits identified as potential economic enhancer.
- Sandiego – 4.1 Mt Cu-Zn-Au-Ag-Pb resource; scoping study (2023) shows 11-year mine life, 750 ktpa throughput, $135 million capex, $177 million pre-tax NPV, and 40 percent IRR.
- Emull – 12.2 Mt Cu-Zn-Pb-Ag maiden resource with significant expansion potential.
- Value-Engineering Upside: Cobalt Blue’s review highlights cobalt inclusion at Sandiego and a centralized processing hub concept to improve margins, extend mine life, and reduce capital intensity.
- Exploration Growth: New targets such as Sandiego North show strong copper anomalies and early drill success, offering resource growth potential.
- Earn-in Partnership: Agreement with Cobalt Blue allows it to earn up to 75 percent interest, bringing technical and financial capability to fast-track development.
Mkuju Uranium Project (Tanzania)
Mkuju is situated immediately to the southeast of the world class Nyota uranium project that was the primary focus of exploration and development feasibility studies by then ASX-listed Mantra Resources (ASX:MRU). Not long after completion of feasibility studies for Nyota in early 2011, MRU announced a AU$1.16 billion takeover offer from the Russian group ARMZ. The takeover was finalised in mid-2011.
During the latter part of 2023, AuKing Mining completed a Stage 1 exploration program at Mkuju which comprised a combination of rock chip, soil geochemistry sampling, shallow auger drilling and initial diamond drilling. Some very encouraging results were obtained from this program which have formed the basis for a 11,000 m drilling program.
