#AYM Anglesey Mining PLC – Half yearly report for the six months to 30 September 2025
Chairman’s Statement and Management Report
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 30th 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.
Financial
The group had no revenue for the period. The loss for the six months to 30 September 2025 was £334,699 (2024 comparative period £311,052) and expenditure on the mineral properties in the period was £50,955 compared to £125,479 in the same period in 2024.
Net current liabilities as at 30 September 2025 were £370,085 compared to net current liabilities of £182,582 at 31 March 2025.

Notes to the accounts
1. Basis of preparation
This half-yearly financial report comprises the unaudited condensed consolidated financial statements of the group for the six months ended 30 September 2025. 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. The half-yearly results for the current and comparative periods have not been audited or reviewed by the company’s auditor.
2. Significant accounting policies
The accounting policies applied in these unaudited condensed consolidated financial statements are consistent with those set out in the annual report and financial statements for the year ended 31 March 2025. 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.
3. Risks and uncertainties
The principal risks and uncertainties set out in the group’s annual report and financial statements for the year ended 31 March 2025 remain the same for this half-yearly period. 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.
4. Statement of directors’ responsibilities
The directors confirm to the best of their knowledge that:
(a) 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
(b) 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.
5. 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.

#AYM Anglesey Mining – Publication of a Conceptual Study of a High-Density Fluid Hydro-Power Energy Storage Project
Anglesey Mining is pleased to publish today, in conjunction with this RNS, a conceptual study of a high-density fluid hydro-power energy storage project at Parys Mountain.
The findings of the conceptual study indicate that there is a positive business case for the project, that the risks identified thus far can be reasonably overcome or mitigated and that the project will advance the delivery of a producing underground polymetallic mine at Parys Mountain.
Background
Anglesey Mining is focused on delivering a polymetallic underground mine at Parys Mountain. To that end, Anglesey’s management are developing strategies to enable investment in the development of Parys Mountain to be incremental, so far as practicable, thus allowing risks to be mitigated in stages before considering options for the next step of development.
Exploring the deployment of RheEnergise’s innovative High-Density Hydro® (HD Hydro) energy storage technology at the Parys Mountain mine site, using the mothballed underground workings and the Morris shaft which was excavated in 1989, fits with the incremental development approach.
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 this 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.
The energy storage project will initially market its products, which are energy storage and electricity grid stability services, to third parties. In the future the Parys Mountain mine may be in a position enter a long term energy offtake contract for the powering of the mine and processing plant, at that time mutually beneficial commercial terms will be explored as the energy storage supply and off-take will be in close physical proximity.
Pre-feasibility study
Anglesey Mining and RheEnergise have elected to immediately commence a Pre-feasibility study (PFS), the first part of which will assess a range of deployment and sizing options, as described in the conceptual study.
A key aspect of this study stage is to identify third party funders for the project including reviewing the range of government incentives available for R&D renewable energy storage projects, highlighting the link to the primary supply of critical minerals for the UK and the creation of jobs and associated economic activity. The structure of how the project is owned, managed and funded is not fixed at this time, so that a bespoke structure can be arrived at that facilitates the third party funding, once identified.
Vision for the partnership between RheEnergise and Anglesey Mining.
From the early work done by RheEnergise and Anglesey Mining, it is clear that there are value enhancing options to be developed and explored through planning a non-caving method of underground mining, in combination with the deployment of high-density hydro energy storage.
- There is an increasing justification for the deployment of on-site energy storage facilities at many mining sites. A consistent and reliable (firm) power supply is generally required not only to ensure environmental, health and safety controls continue to be in place but also importantly for processing operations, because: firstly, re-starting machinery from an unexpected power outage is usually expensive, as it is hindered by having a high tonnage of in-plant inventory, and secondly there is a financial imperative to utilize the capacity of high-cost capital equipment.
- It is likely that firm power will become disproportionally more expensive if a greater share of energy generation onto the power grid is sourced from intermittent renewable technologies, such as wind and solar.
- This energy storage need is juxtaposed, at a typical mine site, with at least two physically unique advantages for deploying high-density hydro power storage: firstly, the core business of underground void creation, some portion of which may be re-purposed within the mining sequence as upper and lower fluid storage reservoirs and secondly, because the on-site processing facility normally generates waste fines in the form of tailings, which through an incremental process could be incorporated into the manufacturing of the high-density fluids required.
This high-density hydro power storage project, the first commercial deployment of RheEnergise’s innovative technology, proving it at technology readiness level 8, would facilitate the practical method by which the power necessary for the mine and processing plant comes from entirely renewable energy sources, both from new and existing suppliers, on the Isle of Anglesey.
Parys Mountain is the UK’s most advanced project for the primary mining of copper, lead, silver and zinc, which is on the Government’s critical minerals list.
