Uranium Exploration Commenced in Namibia
Arkle Resources PLC has commenced its Phase 1 uranium exploration program in Namibia, with airborne and ground-based geophysical surveys now underway on its four recently acquired exploration licenses covering 540 km². The company has completed one line of horizontal loop electromagnetic survey and initiated a substantial airborne survey of over 12,000 line-kilometers, both expected to conclude by mid-March. This work aims to generate high-quality drill targets for a planned Phase 2 program in the second half of 2026, which will include up to 4,000 meters of Reverse Circulation drilling, with the goal of estimating a maiden Mineral Resource Estimate in the first half of 2027. Previous sampling in 2025 confirmed surficial uranium, with assays up to 3,855 ppm U₃O₈. Disclaimer*

[{"type":"text","content":"\n\n26 February 2026\nArkle Resources PLC\n(\"Arkle\" or the \"Company\")\nUranium Exploration Commenced in Namibia\n \nGeophysical Surveys Underway for Extensive Target Generation\non Arkle's Namibian Uranium Projects\n \nArkle Resources PLC (AIM: ARK), the energy metals explorer with a key focus on uranium, is pleased to announce the initiation of its Phase 1 uranium exploration programme in Namibia, with airborne and ground based geophysical surveys now underway.\nIn 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.\nFollowing 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.\nKey Geophysics Workstreams Underway\n· One of three planned lines of horizontal loop electromagnetic survey (\"HLEM\"), primarily to test the potential paleochannels on EPL 8995, has already been completed (see Figure 1).\n· 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.\n· The HLEM work is expected to be completed by early March.\n· Following the receipt of aviation permits, Xcalibur Smart Mapping, a leader in the airborne and mapping geophysics industry, has today commenced a substantial airborne survey of more than 12,000 line-kms at 50m-line-spacing for extensive target generation (See Figure 2).\n· These lines will be 4x tighter than line spacing from the 1970s government data sets, providing significantly higher resolutions to identify both magnetic and radiometric targets on the ground.\n· 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.\n· Analysis of data from both these surveys will be used to prioritise areas for follow-u...
