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 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.

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.
