Uranium Market

During September, the World Nuclear Association ("WNA") released its latest nuclear fuel report for the period 2025 to 2040, which highlighted deficits arising from growing demand for nuclear energy and lack of historic investment in new sources of supply. These forecasts support the positive long-term outlook for uranium demand and prices.

Under the WNA's reference case, global nuclear reactor requirements grow from 179 Mlbs U₃O₈ in 2025 to 391 Mlbs in 2040, a compound growth rate of 5.3 per cent (up from 4.1 per cent in the 2023 report). In this scenario in 2040 there is a deficit to be covered by unspecified supply sources of 193M lbs, or 49 per cent.

World Nuclear Association Reference Scenario

Note: Charts in tonnes U. One tonne U equals 2600 lbs U3O8.

Under WNA's upper scenario, which allows for growth in Small Modular Reactors and greater support for nuclear power globally, reactor requirements increase from 179M lbs U₃O₈ to 532 M lbs in 2040, a compound growth rate of 7.6 per cent (up from 6.0 per cent in the 2023 report).  In this scenario in 2040 there is a deficit to be covered by unspecified supply sources of 319M lbs, or 60 per cent.

World Nuclear Association Upper Scenario

Charts in tonnes U. One tonne U equals 2600 lbs U3O8.

At the end of September, the spot price of uranium (as reported in the Tradetech Exchange Value) was US$83.25 per lb, up by US$6.95 or 9 percent on the previous month's closing price of US$76.30 per lb. Over the last quarter, as also reported in the Tradetech Exchange Value the spot uranium price rose from a low of US$71.50 in July to US$83.25 per lb at the end of the quarter, up 16 per cent.

In addition, the Tradetech long-term price rose $2 from US$82 per lb to US$84 per lb during September.

Active buyers in the market were not only utilities requiring fuel for their own reactors, but also traders, producers, and funds such as Sprott and Yellowcake seeking to acquire inventory in anticipation of rising prices. Market participants are aware of the forecast deficits in the supply of mined uranium in coming years.

Uranium Offtake and Sales Agreements

On 1 August 2025, Aura announced:

·      A long-term offtake agreement with a major U.S. nuclear utility, covering approximately 10% of projected Tiris output (2028-2031). This is the first long term offtake agreement with a nuclear utility and is a landmark for the project and sign of confidence from the industry. The contract is market related with a price collar.  

·      A master spot sales agreement with an international trading group, enabling Aura to benefit from short-term pricing opportunities.

These arrangements complement the existing Curzon offtake agreement, strengthening Aura's uranium sales portfolio and reinforcing Mauritania's credibility as a uranium investment jurisdiction.

Tiris Uranium Project (Mauritania)

Aura continues to advance its Tiris Uranium Project, with the objectives of achieving FID in 1H 2026, followed by commencement of construction of the project.  

Mauritanides 2025 Conference

A delegation led by Mr. Philip Mitchell, Executive Chair participated in the Mauritanides 2025 - the 7th Mauritanian Mining & Energy Conference and Exhibition - held from 6 to 8 September 2025 in Nouakchott, Mauritania. Aura Energy Limited also hosted an exhibition booth during the Conference, showcasing information about the Tiris Project and the company's broader activities. The booth was honoured by a visit from H.E. the President of Mauritania, who showed keen interest in the project and its ongoing developments.

On 6 September 2025, the President of the Islamic Republic of Mauritania, H.E. Mr. Mohamed Ould Cheikh El Ghazouani, received a delegation from Aura Energy Limited led by Mr. Philip Mitchell Executive Chair. The Minister Chief of Staff as well as the Minister of Mines and Industry were present at the meeting.

During the meeting, the Executive Chair presented an overview of the project's current status. The President reaffirmed the Government of Mauritania's full support for the project, emphasizing that the Government stands ready to provide assistance whenever required.

Funding and Investment Partners

·      Aura has made significant progress during the quarter and is in advanced discussions with several potential strategic partners regarding funding and investment in the Tiris asset.

·      These discussions remain confidential and non-binding.

·      Aura is targeting the finalisation of multiple funding and investment options in Q1 2026 to support anticipated FID timing in 1H 2026.

U.S. International Development Finance Corporation ("DFC")

·      Discussions with the DFC for potential project debt funding have advanced toward a credit determination.

·      The Environmental and Social Impact Assessment (ESIA) was published on the DFC website, and the public comment period is complete.

·      DFC's credit determination requires the Project to be execution ready, including finalised construction and supply contracts (such as the Engineering Procurement Construction Management (EPCM) contract) and detailed construction and operating plans.

·      Aura continues to advance these requirements; however, additional time will be required. As a result, DFC funding and the associated Final Investment Decision (FID) are now expected in 1H 2026.

Engineering and Development Activities

·      Basic Engineering continues to be undertaken by Wood. Completion, originally scheduled for late Q3 2025, has been extended to meet execution readiness requirements.

o  Shortlisted western EPCM contractors submitted proposals and completed site visits in late September and early October. Additionally, engineering contracting partner proposals, including alternative execution pathways, have been sought from reputable engineering firms in China and Turkey. Once appointed, the selected engineering contractor will assume control of the flowsheet, cost estimates, development schedule, and finalise subcontracting arrangements.

·      Capital Cost Review:

o  Preliminary results from western EPCM contractors indicated higher capital and operating costs relative to the February 2024 FEED Study.  These estimates are both being reviewed by our internal teams and subjected to competitive tension through the involvement of engineering contractors from China and Turkey.

o  Aura envisages finalising both our engineering approach and the capital and operating cost estimates in Q1 2026.

·      Ongoing Flowsheet Testwork:

The flow sheet consists of 5 key stages

·      A vendor test work program supporting sizing of screening, thickening and filtration equipment is being conducted in Johannesburg, South Africa.  Representative bulk samples for the planned first 4 years of the mine plan  (please refer to 11 September 2024 "Updated Production Target Improves Economics at Tiris") are being assessed by shortlisted equipment vendors to provide detailed operational and sizing parameters.

·      Other Engineering Activities:

o  Dynamic simulation underway pending final test results. Study of opportunities to de-bottleneck process flow sheet and explore opportunities for additional throughput.

o  Power supply study nearing completion. Power generation options are being evaluated with focus on maximising renewable energy components of hybrid power supply.

Häggån Polymetallic Project (Sweden)

The renaissance of interest in nuclear power in the Baltic region was given a major boost at the Nordic Baltic Nuclear Investment Summit, held by the Swedish government in Stockholm, which Aura was pleased to attend. At the Summit, Aura's Executive Chair, Mr Philip Mitchell, met Ebba Busch, Swedish Vice Prime Minister and Minister for Energy Business and Industry, as well as her counterpart in Finland, Sara Multala, Minister of Climate and Environment in Finland.

Countries around the Baltic outlined their ambition to triple nuclear power, with Sweden in the vanguard. Crucially, the Swedish Government has tabled legislation to lift the national ban on uranium mining, with a target implementation date of 1 January 2026.  Subject to the legislation being approved (scheduled for 6 November), this reform could be strategically significant for Aura's Häggån Project, potentially allowing uranium extraction within its existing tenure.

The proximity of the potential change in uranium legislation is exciting investors who are increasingly aware of the potential of Sweden as a major uranium producer, as it hosts some of the world's largest undeveloped uranium hosting deposits.

As the Government's legislative agenda advances and investors recognise the value of Sweden's uranium resources, Aura continues to evaluate strategic options that will highlight the value of the Haggan deposit in our portfolio whilst balancing near-term progress with long-term value creation.

Häggån is a substantial polymetallic deposit, hosting uranium, vanadium, nickel, molybdenum, zinc, and sulfate of potash - all essential to the energy transition. Vanadium is also classified by the European Union as a critical raw material under the Economic Union's Critical Raw Materials Act.

At an operational level, Aura's subsidiary Vanadis Battery Metals has applied for an Exploitation Concession and during the quarter submitted additional information, addressing questions raised by the County Administrative Board, in support of the Häggån's Exploitation Concession application. The next step in the permitting process is a recommendation by the Mining Inspectorate.

Tenement summary

The Company holds the following interest in mining tenements, farm-in and farm-out agreements at the end of the quarter:

Table 1 - Tenement summary

Note:1: Refer also commentary regarding Mauritanian tenement tenure in the Company's 30 June 2025 Annual Report released to ASX on 16 October 2025

In addition, Aura has a farm-in agreement with Nomads Mining Company sarl, Mauritania, through the Aura subsidiary Archean Greenstone Gold Limited which has earned a 70% interest in Nomads 100%-owned gold exploration permit at Tasiast South in Mauritania (refer to ASX announcement dated 11 June 2019 titled "Aura completes farm-in and joint venture agreement"). As announced in the Company's 30 June 2025 Annual Report, the Company has fully impaired its expenditure on these gold assets.

As notified in the 2025 Annual Financial Statements, on 28 August 2025, Nomads Mining SARL ("Nomads") filed a petition to the Commercial Court of Nouakchott seeking to cancel the farm-in agreement and claim damages. The Company is actively defending the matter and based on current legal advice, the likelihood of an outflow of economic resources is considered remote. It is noted that the petition was filed after the Company submitted the registration of the transfer of 70% of Nomad's shares to the Company. However, as the petition was submitted after Aura's registration request, it cannot obstruct the transfer from being registered. The exploration and evaluation asset relating to the Tasiast South Project was fully impaired to nil during the period. The matter will continue to be monitored and the Company will reassess its position if circumstances change.

The Company did not conduct exploration activities during the quarter. There were no tenements acquired or disposed during the quarter.
