ALTONA RARE EARTHS PLC

CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

FOR THE HALF YEAR ENDED 31 DECEMBER 2025

Operational Review

During the period from 1 July 2025 to the date of this report, the Company continued to advance development of its Monte Muambe project in northwest Mozambique, which hosts rare earths, fluorspar and gallium mineralisation.

Monte Muambe Rare Earths

Following the approval of the 25 year mining licence, significant progress was made during the reported period in securing associated landrights (locally known as DUAT).

Engagement with the United States Government, through the United States Trade and Development Agency ("USTDA") and the United States Embassy in Maputo, advanced in relation to potential funding support for a prefeasibility study for the project. A formal proposal was submitted and discussions progressed during the period.

Post period end, the grant agreement with the United States Government through the USTDA was agreed. Under the terms of the agreement, USTDA will provide a grant of US$1.875 million to support key metallurgical and process engineering work required for the prefeasibility study for the Monte Muambe rare earths project.

Monte Muambe Fluorspar and Gallium

During the period, exploration activities at the Monte Muambe project advanced following the reassessment of high-grade fluorspar deposits. The Company reported encouraging trench and soil results which resulted in the discovery of several new high-grade fluorspar and gallium occurrences, and subsequently completed a 3,419m (74 holes) resource drilling programme to further delineate the extent of the mineralised zones.Geochemical and metallurgical samples were collected and submitted for laboratory analysis to support the preparation of a fluorspar and gallium JORC mineral resource estimate ("MRE"). A site visit by the competent person was also completed as part of the verification process for the MRE work.  The MRE is expected to be published in April 2026.

Portfolio diversification

The Company is continuing to pursue a diversified strategy, targeting assets with potential for near-term monetisation alongside longer-term growth opportunities.

Financial Review

During the reporting period the administrative costs reduced from £440,000 to £340,000 against the comparative period. This decrease represents the results of the Company's efforts to reduce corporate costs to ensure that where possible, expenditure is focused on the Company's priority operational activities. The financial loss of the Group for the six months ended 31 December 2025 was £376,000 (H1 2024: £512,000).

Non-current assets increased from £1.7m to £2.3m representing the continued expenditure at Monte Muambe to further the rare earths and fluorspar projects.

In August 2025, the Company raised gross funds of £601,300 through the exercise of 60,130,000 warrants. In October 2025, it raised a further gross funds of £600,000 through the exercise of warrants and used these funds to pay down one of its loan facilities.  The remaining £500,000 debt facility was extended until 30 October 2026. The net cash flow used in operations was £244,000 (H1 2024: £766,000) and net cash outflow from investing activities was £506,000 (H1 2024: £106,000). The cash balance was £348,000 (30 June 2025: £109,000) at the period end.  The cash balance as the date of the publication of these accounts is £1.1 million.

Post Period End Activity

Rare Earths Project

In February 2026, the Company's subsidiary, Monte Muambe Mining Limitada, signed a grant agreement with the United States Government through USTDA. Under the terms of the agreement, USTDA will provide a grant of US$1.875 million to support key metallurgical and process engineering work required for the prefeasibility study for the Monte Muambe rare earths project.

The programme funded under the grant will include a targeted drilling campaign to obtain representative metallurgical samples, comprehensive metallurgical testing, process engineering studies covering beneficiation and hydrometallurgy, environmental and commercial studies, engagement with potential U.S. off‑take partners, and the development of an updated financial model. The grant is non‑dilutive and non-reimbursable, and is intended to advance critical technical workstreams required for the development of the project.

Fluorspar and Gallium Project

Subsequent to the period end, the Company reported further encouraging developments at the Monte Muambe fluorspar project, including strong initial laboratory assay results confirming high-grade fluorspar mineralisation, with individual sample grades reported of up to approximately 93% CaF₂. Metallurgical testing and evaluation work aimed at assessing the potential viability of the production of acid-grade fluorspar started and is currently on-going.

Corporate Activity

Post the year end, the Company raised a further £250,000 through the issue of new ordinary shares and a significant number of warrants were exercised resulting in the issue of new ordinary shares and the receipt of additional funds (approximately £1.0 million) to support the Company's ongoing exploration and development activities.

Harvey Sinclair was appointed as Non-Executive Chairman of Altona effective 1 November 2025, and Simon Charles stepped down from the Board.

Altona shares started to cross-trade on the OTCQB on 18 March 2026.

Outlook

During the course of 2026, the Company intends to focus its activities on:

1)    Progressing the development of the Monte Muambe rare earths project in conjunction with the USTDA.

2)    Continuing to assess the potential viability of the Monte Muambe fluorspar project, initially with an MRE, followed by a scoping study.

3)    Reviewing potential pathways for the extraction of gallium from fluorspar ore

4)    Assessing and generating potential business opportunities with respect to Monte Muambe with US (or allied) entities arising from the OTCQB listing, the USTDA grant, and the current geopolitical context around rare earths and gallium.

5)    Continuing the implementation of the Company's diversification strategy though the acquisition of a pipeline project meeting the Company's specifications including a low acquisition cost and a short timeline to production and cash flow. Several opportunities have been identified and are at an advanced stage of technical review.

NOTES TO THE CONDENSED INTERIM FINANCIAL STATEMENTS

FOR THE HALF YEAR ENDING 31 DECEMBER 2025

1.         GENERAL INFORMATION AND BASIS OF PREPARATION OF HALF YEAR REPORT

(a) General Information

Altona Rare Earths Plc, (the "Company") is a publicly listed company incorporated and domiciled in England and Wales. Its registered office is at Eccleston Yards, 25 Eccleston Place, London SW1W 9NF.

The Company's principal activity is focused on the discovery and development of Critical Raw Materials mining projects in Africa. 

These condensed interim financial statements were approved for issue on 25 March 2026.

These condensed interim financial statements do not comprise statutory accounts within the meaning of section 434 of the Companies Act 2006.  Statutory accounts for the year ended 30 June 2025 were approved by the board of directors on 24 October 2025 and delivered to the Registrar of Companies. The auditor's report on those financial statements was unqualified but did include a reference to the material uncertainty surrounding going concern, to which the auditors drew attention by way of emphasis of matter and did not contain a statement under s498 (2) - (3) of Companies Act 2006. The Company's auditors have not reviewed these condensed interim financial statements.

(b)   Basis of Preparation

This condensed consolidated interim financial report for the half-year reporting period ended 31 December 2025 has been prepared in accordance with the UK-adopted International Accounting Standard 34, 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

This interim financial report does not include all the notes of the type normally included in an annual financial report.  Accordingly, this report should be read in conjunction with the financial statements for the year ended 30 June 2025, which has been prepared in accordance with both "International Accounting Standards in conformity with the requirements of the Companies Act 2006" and "International Financial Reporting Standards adopted pursuant to Regulation (EC) No 1606/2002 as it applies in the European Union", and any public announcements made by Altona Rare Earths Plc during the interim reporting period.

The financial statements have been prepared on a going concern basis.  The Group's assets are not currently generating revenues, an operating loss has been reported and an operating loss is expected in the 12 months subsequent to the date of these financial statements.  The Company has raised funds in the period, paid down one loan facility and extended another until 30 October 2026. It has also received funds from the exercise of warrants and expects to continue to receive funds from these warrants over the next accounting period.  Therefore, the directors consider it appropriate to prepare the financial statements on a going concern basis. The financial statements do not include the adjustments that would result if the Group were unable to continue as a going concern.

The accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period.  There were no new or amended accounting standards that required the Group to change its accounting policies.  The directors also considered the impact of standards issued but not yet applied by the Group and do not consider that there will be a material impact of transition on the financial statements.  The Group's results are not subject to seasonal variations.

2.            CRITICAL ESTIMATES AND JUDGEMENTS

The preparation of interim financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, income and expense. Actual results might differ from these estimates.

In preparing these condensed interim financial statements, the significant judgements made by management in applying the Group's accounting policies and the key sources of estimation uncertainty were the same as those that applied to the financial statements for the year ended 30 June 2025.

3.            SEGMENT INFORMATION

For the purpose of IFRS 8, the Chief Operating Decision Maker "CODM" takes the form of the board of directors. The directors are of the opinion that the business of the Group focused on three reportable segments as follows:

·    Head office, corporate and administrative, including parent company activities of raising finance and seeking new investment and exploration opportunities, based in the UK;

·    Mineral exploration, based in Mozambique and Botswana, and

·    Other costs, mostly administrative activities, based in Mauritius and Africa.

The geographical information is the same as the operational segmental information shown below.

4.         ADMINISTRATIVE EXPENSES

5.            FINANCE COSTS

6.            LOSS PER SHARE

The basic loss per share is derived by dividing the loss for the period attributable to ordinary shareholders by the weighted average number of shares in issue.

As the inclusion of the potential ordinary shares would result in a decrease in the loss per share they are considered to be anti-dilutive and, as such, the diluted loss per share calculation is the same as the basic loss per share.

7.            INTANGIBLE ASSETS

8.            TANGIBLE FIXED ASSETS

9.            TRADE AND OTHER RECEIVABLES

10.          TRADE AND OTHER PAYABLES

11.          LOANS AND BORROWINGS

In October 2025, the Company repaid the outstanding loan facility of £600,000. £132,000 of accrued interest was satisfied through the issue of ordinary shares at £0.01 per share. Interest was calculated and paid up to the 30 October 2025.

On 27 June 2024, the Company entered into two debt facilities totaling £900,000 with a 12% fixed interest rate, both due for repayment by 30 October 2025. An existing convertible loan note of £200,000 was rolled up into these facilites with the same terms.

12.          SHARE CAPITAL

13.          WARRANTS

The following table sets out the movement of warrants during the period, no warrants were exercised during the period: 

14.       COMMITMENTS AND CONTINGENT LIABILITIES

As at 31 December 2025 the capital commitments of the Group relate to Phase 3 of the Farm-Out Agreement in Mozambique which sets out a minimum spend of $2m over 2 years. This Phase and the related capital commitments can be extended with further payments.

15. RELATED PARTY TRANSACTIONS

On 26 August 2025, the Company issued 1,949,000 ordinary shares to Directors and Senior Management in lieu of salaries and fees amounting to £31,498 at an average of £0.016 per ordinary share.  Louise Adrian also works as a consultant for Orana Corporate LLP who provide the Company with accounting, bookkeeping and company secretarial services. During the year these services cost the Company £24,000.

16. POST REPORTING DATE EVENTS

In the period between 1 January 2026 and the date of the publication of these accounts, the Company made the following changes to its capital structure:

-      Issue of 59,933,333 ordinary shares from the exercise of warrants raising funds of £1.0 million

About Altona Rare Earths Plc 

Altona Rare Earths Plc (ticker: REE) is a London Main Market-listed exploration and development company focused on unlocking the value of critical raw materials across Africa. The Company is pursuing a diversified strategy, targeting assets with potential for near-term monetisation alongside long-term growth.

The multi-commodity Monte Muambe Project in northwest Mozambique is a highly prospective tenement hosting rare earths, fluorspar, and gallium mineralisation. Since acquiring the project in June 2021, Altona has drilled over 7,800 metres, delivering a maiden JORC Mineral Resource Estimate of 13.6Mt at 2.42% TREO, secured a 25-year mining licence (granted December 2024), and published a Competent Person Report and scoping study for the rare earths component of the project (October 2023).

The Company has received a US$1.875 million grant from USTDA to advance the rare earths project through the prefeasibility stage.

In parallel, Altona is progressing plans to fast-track the development of high-grade fluorspar veins identified along the western and southern margins of Monte Muambe, with a targeted production of 50,000 tonnes per annum of acid-grade fluorspar over a minimum 12-year mine life. Acid-grade fluorspar is a key input in a wide range of applications, including hydrofluoric acid, lithium battery electrolyte production, and nuclear fuel refining, placing Altona in a strong position to supply this critical material.

The discovery of gallium mineralisation, with grades up to 550 g/t identified to date, adds further value to Monte Muambe. The Company has established that gallium will be concentrated in fluorspar production tailings and is assessing its possible recovery as a by-product of fluorspar.

Altona's diversified portfolio also includes the Sesana Copper-Silver Project in Botswana, strategically located just 25 km from MMG's Khoemacau Zone 5 copper-silver mine. Situated on a recognised regional contact zone for copper deposits, Sesana represents a compelling exploration opportunity aligned with Altona's growth strategy.

With a unique combination of critical raw materials projects, Altona is well positioned to contribute to the global supply of highly sought commodities essential for clean energy, high technology, defence and industrial applications.

The Company and the Board remain actively focused on identifying and evaluating additional projects that align with our investment profile and strategic objectives, leveraging our extensive network and combined industry experience to uncover compelling opportunities that can drive long-term growth.
