Announcement PDF RNS Number : 2000G Alba Mineral Resources PLC 05 November 2025 Alba Mineral Resources Plc / EPIC: ALBA / Market: AIM / Sector: Mining 5 November 2025 Alba Mineral Resources Plc ("Alba" or the "Company") Maiden Drilling Programme Commences at Finnsbo Alba Mineral Resources plc (AIM: ALBA), the gold and critical raw materials focused exploration and development company, is pleased to announce that drilling has commenced at Finnsbo, the high-grade gold and rare earths prospect which Alba is earning into in southern Sweden ("Finnsbo" or the "Project"). Highlights · Drilling has commenced at Finnsbo, seeking continuity of high-grade gold, copper and rare earth mineralisation. · Previous geochemical sampling at Finnsbo returned assay results of: o up to 3.5% Total Rare Earth Oxides (TREO) (with overall grades ranging from 0.5% to 3.5% TREO), with 37-38% of the TREO comprising high-value NdPrDy (neodymium-praseodymium-dysprosium) oxides; and o up to 27g/t gold (with overall grades ranging from 7 to 27g/t) and 2.9% copper (with overall grades ranging from 0.9% to 2.9%). Details Alba has commenced drilling at the Finnsbo Project in southern Sweden (Figures 1 and 2). This maiden drilling campaign is expected to comprise three drill holes for around 300 metres in total (Figure 3). The programme is expected to last about two weeks. Previous geochemical sampling at Finnsbo returned assay results at the "POP 2" location of up to 3.5% Total Rare Earth Oxides (TREO) (with overall grades ranging from 0.5% to 3.5% TREO), with 37-38% of the TREO in each case being made up of high- value NdPrDy (neodymium-praseodymium-dysprosium) oxides, as well as gold and copper grades of up to 27g/t (with overall grades ranging from 7 to 27g/t) and 2.9% (with overall grades ranging from 0.9% to 2.9%) respectively. Samples taken by Alba from the same location were found to contain visible gold and returned assay results including grades of 9.72 grams per tonne (g/t) gold and 2.36% TREO. Subsequent to this sampling, Alba commissioned a specialist geophysics contractor to carry out a ground-based geophysical survey at Finnsbo. The results of the survey strengthened the indications that the more unique "POP 2" style of high-grade gold, copper and rare earth element ("REE") mineralisation is of magmatic origin and related to the intrusive tonalite. This confirmed the Company's thinking that the next stage of field work should focus on core drilling the contact zone starting at the POP 2 location and stepping out towards the southeast, seeking continuity of high-grade gold, copper and rare earth mineralisation. This is the objective of the present drilling campaign. Figures 1 and 2: Drill rig in background; geologists examining the drill core.

Alba has the right to earn into the Finnsbo Project in stages, as per the Company's announcement of 6 November 2024, with the first stage comprising the right to spend £100k on qualifying expenditure over an initial 12-month period in order to earn a 25% interest in the Project, with the further right thereafter to earn or acquire in further stages up to a 100% interest in the Project.
