Uranium Market
On 29 January 2026, the TradeTech uranium price was US$101.50/lb with futures quotes for 2026 delivery in the US$101-104/lb range. At the end of December 2025, the spot price of uranium (as reported in the TradeTech Exchange Value) was US$83.25 per lb, up US$6.95 or 9 per cent on the previous month's closing price of US$76.30 per lb. Over the December 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, a gain of 16 per cent.
In light of their heavy forecast power needs for data centres and AI infrastructure, US technology companies continue to partner with nuclear energy companies. This highlights the benefits of nuclear power as a rare source of large scale, low emission, reliable base load power. Examples include Google's 25-year power offtake agreement with NextEra, Microsoft's 20-year power purchase agreement with Constellation, and Meta's offtake agreements with Vistra. Meta also announced a partnership with Oklo to help advance its reactor technology and develop a new nuclear energy campus.
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 acutely aware of the forecast deficits in the supply of mined uranium in coming years.
In the U.S. uranium was officially added back to the Critical Minerals List by the U.S. Geological Survey on 14 November 2025. This followed the signing of a partnership in October between the U.S. Government and Westinghouse Electric's owners to build at least US$80 billion worth of nuclear reactors and at a time when growth in artificial intelligence data centres has driven an increase in U.S. power demand for the first time in two decades, straining part of the grid.
The recent legislative changes in Sweden and the proposed generous financial framework to support new nuclear reactor construction reflects how mid-sized European economies are positioning nuclear as a core part of their clean-energy future.
Tiris Uranium Project (Mauritania)
Aura continues to advance its Tiris Uranium Project, with the objectives of achieving FID in Q3 2026. Shortly thereafter, formal conditions precedent will be finalised enabling construction of the project to commence.
As discussed during the Chairman's Address - 2025 Annual General Meeting ("AGM") on 25 November 2025, the Basic Engineering study was placed on hold pending the completion of test work to identify the optimal processing approach following dissolution of uranium in the leach plant. In particular, the test work is focused on the separation of the uranium-bearing pregnant leach solution from the solid, clay-rich residues generated by the plant (dewatering).
The Company and its main offtake partner, a leading US nuclear utility, acknowledge that the condition precedent, which required FID by 31 December 2025, was not fulfilled. The parties are nevertheless mindful of the strategic value of the contract to each party and are working collaboratively to enable the contract to remain effective.
Engineering and Development Activities
Aura currently anticipates the Basic Engineering study will be completed in Q2 2026. Potential strategic investors and financiers are aware of the revised test work program outlined above and continue to see the development of Tiris as potentially marking the emergence of a new, strategically important African uranium province to rival Niger and Namibia.
The key aspect of the test work that needs to be completed relates to the dewatering of the slurry once it has been leached and before the uranium is harvested in the ion exchange plan. Four options are being investigated with detailed test work underway:
o Centrifuge;
o Counter Current Decantation ("CCD");
o The use of polymers to agglomerate fine and coarse particles facilitating; and
o Resin in Pulp.
· Ongoing Flowsheet Test work:
The flow sheet consists of five key stages

Funding and Investment Partners
As Aura moves closer to FID, the Company is seeking to progress funding arrangements that reflect three principles:
1. They must offer fair value for shareholders
2. The financing terms should reflect the long life of the resource
3. They should represent the lowest available cost of capital
Aura is following a structured and disciplined financing process that ensures the Company will enter project development from a position of stability and confidence and continues to engage with potential strategic partners around the world.
U.S. International Development Finance Corporation ("DFC")
· DFC's new Chief Executive Officer (Ben Black) was confirmed by the U.S. Senate with bipartisan support in October 2025.
· In December 2025, DFC received a six-year reauthorization with expanded authorities, which included an investment cap increase by over 300% to US$205 billion and the authority to make substantial minority equity investments (up to 40% ownership).
Häggån Polymetallic Project ("Häggån Project")
Post-quarter end, a valuation of C$50 million (A$55 million) was established for the Häggån project as MMCAP International Inc., SPC and other strategic investors agreed to provide funding of C$10 million for a 19.7% interest in the Häggån Project.
Aura has entered into a binding agreement to transfer 100% of the Häggån project to SIU Metals Corp ("SIU Metals")., an unlisted Canadian public company, in consideration for acquiring shares in SIU Metals. The agreement will result in SIU Metals being the 100% owner of the Häggån project.
Aura will retain 78.7% ownership of SIU Metals, the strategic investors will own 19.7% after contributing C$10 million via a private placement, and other investors will own 0.6%. SIU Metals' existing shareholders will retain 1%. SIU Metals intends to seek a stock market listing on the TSX Venture Exchange in connection with the transaction by June 2026.
Aura will rename SIU Metals and appoint new officers and directors on closure of the transaction, which is expected in June 2026. Funds committed by the strategic investors will be used for the advancement of the Häggån project, including permitting and resource expansion through continued exploration including on surrounding tenements.
On 5 November 2025, the Parliament of Sweden voted to overturn the uranium mining ban effective 1 January 2026. Uranium has now been reclassified as a concessional mineral under the Minerals Act allowing exploration and extraction permits under existing mining laws and signals the rebirth of Sweden's nuclear industry. Sweden has 27% of Europe's known uranium within its bedrock[1] and already extracts uranium as a waste product when mining for other metals. The government is also proposing to amend the Nuclear Activities Act so that uranium mining would not be considered a nuclear facility, which currently entails a municipal veto. It is anticipated that amendments to the Act will be put before Parliament around the end of Q1 2026, and new legislation enacted in July 2026.
With the uranium mining ban lifted at the start of the year, Aura's subsidiary Vanadis Battery Metals ("Vanadis") notified the Swedish Mines Inspectorate that it will seek to have the Häggån exploitation licence application amended to include uranium exploitation within its existing tenure.
On 24 November Sweden's Mining Inspectorate "Bergsstaten" granted Vanadis an exploration permit for the Gräsmyråsen nr 1 tenement in Jamtland with validity to 20 November 2028. The Gräsmyråsen tenement covers 1012.12 hectares, lies to the west of, and adjacent to, Vanadis' existing Häggån nr 1 tenement. The new exploration permit will supplement the Company's existing assets and adds coordination benefits, making exploration work more efficient and cost effective in this high potential area.

Häggån is a substantial polymetallic deposit, hosting uranium, vanadium, nickel, molybdenum, zinc, and sulfate of potash - all essential to the energy transition sector. Vanadium is also classified by the European Union as a critical raw material under the Economic Union's Critical Raw Materials Act.
Corporate
During the quarter, Andrew Grove resigned as Managing Director and CEO. Executive Chair Phil Mitchell assumed accountability for day-to-day operational management ensuring continuity, specifically regarding critical current workflows including funding discussions with the U.S. International Development Finance Corporation and potential strategic partners.
A process has commenced to appoint a Lead Independent Director from amongst the Non-Executive Directors for the period that Mr Mitchell acts in the role of Executive Chairman.
My Bryan Dixon advised the Company that he would not stand for re-election at the AGM in November and resigned as a Non-Executive Director and Chair of the Audit and Risk Committee effective at the conclusion of the AGM.

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, some of Nomads Mining SARL ("Nomads") shareholders 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 an application for the registration of the transfer of 70% of Nomad's shares to the Company and that in December 2025, the Commercial Court of Nouakchott ruled in favour of the Company and ordered the registration of ownership interest of the Company in the official Register of Commerce. Philip Mitchell is registered as the sole "gerant" of Nomads. The Company will seek to enforce its position and the court orders.
The Company did not conduct exploration activities during the quarter. As outlined above a new tenement was granted in Sweden.
Outlook
Both the Tiris Uranium Project and the Häggån Polymetallic Project have outstanding fundamentals, are located in supportive jurisdictions and are underpinned by favourable market conditions. Aura's near-term goal remains unchanged: to deliver the Tiris Uranium Project into production safely, responsibly, and in a way that enhances value for all stakeholders, including host communities, partners and shareholders. Over the longer term the Company will participate in the rebirth of Sweden's nuclear industry and unlock the value of the Häggån asset.
