Corporate Presentation · New corporate presentation available on Company's website. Details Motzfeldt Critical Metals (Greenland) As previously announced, Alba has agreed to acquire a 51% interest in the Motzfeldt Critical Metals Project in south Greenland. The current operator of the Project, Elemental Rare Metals Ltd, successfully completed a field programme last month including the following: - A ground radiometric survey at the top of the high-grade rare earth prospect, Merino; - Primary analysis of Merino to test the hypothesis that Aries-type mineralisation lies at depth; - The collection of ~100 samples from across Merino for assay, petrography and mineralogy; Figure 1: Sampling at Aries Deposit, Motzfeldt, July 2025 - Analysis and sampling of the Merino "chimney" structures to test the hypothesis that they form from escape of mineralisation; - A photogrammetric drone survey at both Merino and the central Aries deposit area, which will allow for the creation of detailed 3D models and accurate terrain maps, aiding in geological mapping and the future planning of mining operations. - Analysis of the far face opposite Merino to assess it potential as a third extension of Merino. Further results will be announced once a selection of the Merino samples have been assayed at an independent laboratory and the data from the radiometric survey has been assessed and interpreted. Being able to delineate a mineralised zone at Merino will be significant for the overall scale of the Motzfeldt Project, as it will expand the footprint of the project greatly, joining Merino to Aries ~1km to the south (Figure 2). As previously announced, in the coming months Alba also intends to carry out a detailed mineralogical and metallurgical study of the Aries deposit, in order to establish the optimal processing routes for Aries material. This will be undertaken using the 2.5 tonne bulk sample which has previously been collected from the Aries plateau by the current operator. In this regard, the Company has now selected its preferred contractor to supervise the study programme. They have requested a representative 300kg sub-sample from the bulk sample. This sub-sample will be crushed and delivered to the contractor in the coming weeks. They will then carry out detailed mineralogical studies on the ore, following by metallurgical test work involving magnetic separation, gravity separation and flotation. The full programme is expected to take some 3-4 months to complete. The Company also intends to commence a Scoping Study or Preliminary Economic Assessment for the Aries Deposit in due course. Finally, Alba has held initial discussions with governmental agencies in order to explore the routes for securing non-dilutive or low-cost funding and other support for the development of Motzfeldt.

Clogau Gold Mine (Wales, UK) A successful preparatory blast was conducted at the Clogau St-David's Mine ("Clogau") in late July. The purpose was to clear out a section at the Llechfraith Target on Level 5 which had not been fully cleared out in the last phase in order to allow the next phase of drilling and blasting to commence from a clean face. This preparatory blast was conducted under controlled conditions by specialist explosives contractors Orica. The ongoing health, safety and compliance programme at Clogau has included completion by Alba's specialist contractors of a ventilation survey and a safe working load survey. A recent periodic visit by HMIM has recommended certain further assessments and works be completed underground prior to the resumption of further blasting. It is expected that these may take about one month to carry out in total, depending on contractor availability. The purpose of the next phase of blasting at the Llechfraith Target is to extract several hundred tonnes of fresh ore from within the projected payshoot (Figure 3) and to process and refine that ore for its gold content. Depending on the results achieved, this will support the further development of the Llechfraith Target.

The arrow shows the direction of the next phase of drilling and blasting on Level 5, within the projected payshoot. Corporate Presentation The Company's new corporate presentation can be viewed at: https://albamineralresources.com/activity-updates/new-corporate-presentation Company Comment George Frangeskides, Alba's Executive Chairman, commented: "We are pleased to be able to report on the progress made this summer at the Company's new critical metals project, Motzfeldt, in south Greenland. We have collected new data in relation to the exciting Merino prospect which should, in the coming weeks and months, help us to assess and develop its potential as another key source of critical raw materials within the Motzfeldt Centre, alongside the existing Aries Deposit which lies just 1km to the south. "Meanwhile, we have started work to update the key parameters around the more advanced Aries Deposit, with the selection of a main consultant to oversee a very detailed mineralogical and metallurgical test work programme, which will in turn feed into a new Scoping Study for Aries. "Back in the UK, we are having to do some remedial works in the mine at Clogau before we can continue with the next phase of drilling and blasting at our key Llechfraith gold target. This comes with the territory of operating an existing mine, where health & safety is paramount. Our team is working round the clock to project manage the upcoming work as efficiently as possible so that we can resume the blasting phase."
