Arkle Resources PLC Announces Drilling Update For Stonepark Zinc Project Arkle Resources PLC announced that Group Eleven intends to expand drilling at the Stonepark Zinc Project from approximately 3,000 m to approximately 15,500 m. Group Eleven is the Operator of Stonepark in which Arkle holds a 22.36% interest. Arkle co-discovered the Stonepark zinc deposit in County Limerick - now Ireland's second largest undeveloped resource - in a joint venture with Teck Ireland. Teck Ireland's interest was acquired by Group Eleven. Group Eleven (in which Glencore is a 13% shareholder) continues to advance the project alongside Arkle. Stonepark is formed of five contiguous prospecting licences covering an area of 148 km² and is adjacent to Glencore's Pallas Green zinc project, one of the world's largest undeveloped zinc-lead deposits at 45.4 Mt. Stonepark has an Inferred Mineral Resource of 5.1 Mt grading 11.3% combined zinc and lead (8.7% Zn, 2.6% Pb) - and the deposit remains open along and across strike. It is higher grade and shallower (190-395 m depth) than the neighbouring Pallas Green deposit (8.4% Zn+Pb). Ireland is ranked number one in the world for zinc discovered per square kilometre. It is home to some of the world's largest and highest-grade zinc deposits, including Tara (120 Mt+ mined since 1977, Europe's largest zinc mine), Lisheen (22.3 Mt at 11.7% Zn), and Galmoy (8Mt at 12% Zn). Six zinc mines have been permitted and operated over the past 60 years, and every major Irish zinc discovery has been profitably mined. Majors active in Ireland include Boliden and Glencore. The joint venture's thesis is that the Carrickittle area within the Stonepark project may host a "mirror image" of the mineralising system that created Glencore's adjacent Pallas Green deposit on the opposite side of the Limerick Volcanic Complex. In 2022, drilling at Carrickittle West intersected the first major fault structure directly drilled in the Limerick region - a fault with 150 m of vertical displacement and zinc mineralisation on both sides. Three follow-up holes were drilled on Stonepark ground in late 2024, totalling 1,372 m at depths of 350-550 m. Results released in 2025 demonstrated proximity to strong mineralisation. Group Eleven's recent focus has been on nearby exploration at its Ballywire prospect (on a wholly owned Group Eleven licence, southeast of Stonepark) indicating high-grade zinc-lead-silver mineralisation over a 2.6 km trend that remains open in all directions. Group Eleven plans step-out drilling around the known resource at Stonepark as well as a follow-up drill programme on the Carrickittle West prospect (within the Stonepark licence) and its announced intention to drill approximately 15,500 m at Stonepark is welcomed by Arkle's Board.

Arkle Resources PLC Announces the Initiation of Its Phase 1 Uranium Exploration Programme in Namibia Arkle Resources PLC announced the initiation of its Phase 1 uranium exploration programme in Namibia, with airborne and ground based geophysical surveys now underway. In January 2026, Arkle completed a transformative acquisition of four uranium exploration licences in Namibia's Erongo Region, covering 540 km2. As a result, Arkle now provides investors with unique London Stock Exchange-listed uranium discovery exposure in one of Africa's key uranium belts, proximal to some of the world's largest uranium producers. Following a successful sampling programme in 2025, which confirmed the presence of surficial uranium on Arkle's licences, the Company is fully funded to advance a two-phase work programme as detailed further below. One of three planned lines of horizontal loop electromagnetic survey ("HLEM"), primarily to test the potential paleochannels on EPL 8995, has already been completed. The HLEM survey will assist in mapping the basement rock profile of channels allowing geophysicists to determine the potential depth and extent of fill across the paleochannels. The airborne survey is expected to be completed by mid-March with final delivery of the processed data anticipated within 30 days of completion of data acquisition. Analysis of data from both these surveys will be used to prioritise areas for follow-up mapping and sampling. This in turn will guide the identification of drill targets. Phase 2 exploration work to begin in H2 2026 will focus on targets developed from Phase 1 and will include detailed mapping (with potential for further geophysical surveys), additional sampling, and up to 4,000 metres of Reverse Circulation drilling. A successful 2026 drill programme would be followed by a phase 3 programme which would include detailed infill drilling, leading to the estimation of a maiden Mineral Resource Estimate in first half of 2027. Initial work on EPL 7986 will be focused on mapping, sampling and developing a model of the alaskite outcrop. A sampling programme was carried out in 2025 comprising 178 samples taken from small pits dug to depths of 0.35 to 0.5 m. Highlights from the programme included: EPL 8995 and 8290 Uranium in calcrete values up to 2,782 ppm U3O8 - surficial uranium confirmed in all areas surveyed; Uranium in alaskite values up to 3,855 ppm U3O8 - strong indications of the presence of basement highs and the identification of alaskite mineralisation surrounding Trekkopje's large paleochannel systems, which may extend into Arkle's tenements EPL 7986 - Uranium in alaskite value up to 2,923 ppm U3O8 - adjacent to Rossing and located on margins of the same domal structure and mineralisation.
