Half-year Results

During the half year period, we were pleased to publish a conceptual study of a high-density fluid hydro-power energy storage project at the mine.

The findings of the conceptual study led to the commencement of a pre-feasibility study (PFS) in the energy storage scheme and we have published the proposed operational methodology and revenue streams associated with the project in terms of both Long Duration Energy Storge (LDES) and how that might be the catalyst for the commencement of mining of the Parys Mountain VMS mineral deposits.

Our investigations show there is a positive business case for the energy project on a standalone basis, that the risks identified thus far can be reasonably overcome or mitigated. Elements of the energy storage project scope, for example: the de-watering and refitting of the Morris shaft for material and personnel hoisting, the dewatering of the workings emanating from the Morris shaft 280m below the surface, the upgrading of the power-line to site, the on-going environmental and social studies and the deployment of impact avoidance, mitigation and compensation strategies, are each synergistic with the first steps of establishing a modern underground mine on Parys Mountain.

It is an essential and clear intent of the energy project that Anglesey Mining retains all the optionality that it currently has for the construction and commissioning of an underground mine, and that the hydro energy pumped storage project should not detract from those options over the medium and long term.

In the period to the 30

th

September 2025, we unfortunately had to announce the termination of our management rights and obligations over Grangesberg Iron AB (GIAB). Under a shareholders’ agreement our 100% owned subsidiary, Angmag AB, and therefore Anglesey Mining, had management rights with the ability to appoint the majority of the Board of GIAB. The Agreement had an initial term of 10 years from 28 May 2014, extendable on a year-to-year basis, unless terminated on one year’s notice. On 28 May 2024, Eurmag AB, which holds the remaining 50.2% of GIAB, gave notice of termination of the Agreement.

As at 31 December 2024, GIAB had loans outstanding to its senior debt holder of approximately US$9.0 million. Despite the best efforts of the Company, revised terms and conditions for the senior debt could not be arrived at such that the Board of Anglesey Mining could then explore the raising of funds to facilitate a settlement of this debt and therefore management of GIAB reverted to Eurmag AB, GIAB’s 50.2% shareholder, with Anglesey retaining its 49.8% ownership interest.

Post the end of the half year period, on 5 December 2025 the Company announced that it had entered into a binding letter of intent with its largest shareholder and largest creditor Energold Minerals Inc. whereby Anglesey will eliminate approximately £4 million of debt in exchange for its interest in GIAB and holding of Labrador Iron Mines Holdings Limited, reducing total outstanding debt to approximately £100,000.

Energold has also provided immediate funding to Anglesey of £350,000 through the purchase of non-voting exchangeable warrants.

The Board believes that the restructuring of the Company’s balance sheet, in addition to the investment of fresh funds by Energold, will place the Company in a materially stronger position from which to pursue its primary objective of advancing Parys Mountain.

Finally, at the beginning of December 2025, we were delighted to welcome Brendan Cahill and Jim Williams to Anglesey’s board.

It has been prepared in accordance with the Disclosure and Transparency Rules of the Financial Conduct Authority, the requirements of IAS 34 - Interim financial reporting (as adopted by the UK) and using the going concern basis. The directors are not aware of any events or circumstances which would make this inappropriate. It does not constitute financial statements within the meaning of section 434 of the Companies Act 2006 and does not include all of the information and disclosures required for annual financial statements. It should be read in conjunction with the annual report and financial statements for the year ended 31 March 2025 which is available on request from the company or may be viewed at www.angleseymining.co.uk/accounts.

The financial information contained in this report in respect of the year ended 31 March 2025 has been extracted from the report and financial statements for that year which have been filed with the Registrar of Companies. The report of the auditors on those accounts did not contain a statement under section 498(2) or (3) of the Companies Act 2006 and was not qualified.

There are no new standards, amendments to standards or interpretations that are expected to have a material impact on the group's results.

The group has not applied certain new standards, amendments and interpretations to existing standards that have been issued but are not yet effective. They are either not expected to have a material effect on the consolidated financial statements or they are not currently relevant for the group.

They can be summarised as: development risks in respect of mineral properties, especially in respect of permitting and metal prices; liquidity risks during development; and foreign exchange risks. More information is to be found in the 2025 annual report – see note 1 above.

Statement of directors' responsibilities

The directors confirm to the best of their knowledge that:

• the unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of IAS 34 Interim financial reporting (as adopted by the UK); and
• the interim management report includes a fair review of the information required by the FCA's Disclosure and Transparency Rules (4.2.7 R and 4.2.8 R).

This report and financial statements were approved by the board on 19 December 2025 and authorised for issue on behalf of the board by Andrew King, interim chairman and Rob Marsden, chief executive officer.

Activities

The group is engaged in mineral property development and currently has no turnover. There are no minority interests or exceptional items.

6.

Earnings per share

The loss per share is computed by dividing the loss attributable to ordinary shareholders of £0.3 million by 484 million - the weighted average number of ordinary shares in issue during the period. The comparative figures were a loss to 30 September 2024 of £0.3m divided by 442 million shares. However where there are losses the effect of outstanding share options is not dilutive.

7.

Business and geographical segments

There are no trading revenues. The cost of all activities charged in the income statement relates to exploration and evaluation of mining properties. The group's income statement and assets and liabilities are analysed as follows by geographical segments, which is the basis on which information is reported to the board.

8.

Deferred tax

There is an unrecognised deferred tax asset of £1.6 million (31 March 2025 - £1.6m) which, in view of the group's results, is not considered to be recoverable in the short term. There are also capital allowances, including mineral extraction allowances, of £14.5 million (unchanged from 31 March 2025) unclaimed and available. No deferred tax asset is recognised in the condensed financial statements.

9.

Mineral property exploration and evaluation costs

Mineral property exploration and evaluation costs incurred by the group are carried in the unaudited condensed consolidated financial statements at cost, less an impairment provision if appropriate. The recovery of these costs is dependent upon the successful development and operation of the Parys Mountain project which is itself conditional on financing being available to fund such development. During the period activities were limited and no drilling took place.

10.

Investments

Labrador – Canada

The group has an investment in Labrador Iron Mines Holdings Limited, (LIM) a Canadian company which is carried at fair value through other comprehensive income. The group’s holding of 19,289,100 shares in LIM (12% of LIM’s total issued shares) is valued at the closing price traded on the OTC Markets in the United States. In the directors’ assessment this market is sufficiently active to give the best measure of fair value, which on 30 September 2025 was 1 US cent per share (2024 – 8 US cents). As at 19 December 2025 the share price was 2 US cents per share.

Grängesberg - Sweden

The group has, through its Swedish subsidiary Angmag AB, a 49.8% ownership interest in Grängesberg Iron AB an unquoted Swedish company (GIAB) which holds rights over the Grängesberg iron ore deposits.

The directors assessed the fair value of the investment in Grängesberg under IFRS 9 and consider the investment’s value at 30 September 2025 to be £633,170.
