Aterian plc Commences Ground-Based Magnetic Geophysical Survey At Agdz Copper-Silver Project Aterian plc announced the commencement of a ground-based magnetic geophysical survey at its 100%-owned Agdz Copper-Silver Project ("Agdz" or the "Project") in the Kingdom of Morocco. The programme represents a key step in advancing Agdz from surface discovery towards drill target definition, following the Company's recent announcement on 29 January 2026, which highlighted a significant expansion in the footprint of copper-silver mineralisation. 111 line km ground magnetic survey underway across 11.20 km2. c.28% of the planned survey completed. Survey targeting fault-controlled copper-silver bearing breccias identified in recent fieldwork. Mineralisation traced over up to 0.9 km strike, with potential for further extension. Following up on historic and recent assays, including 3.47% Cu with 136 g/t Ag and 1.34% Cu with 31 g/t Ag. Expanding total ground magnetic coverage to 322 line km over 20.8 km² (from 195 line km historically). This objective is to rapidly define new drill-ready targets across an expanding mineralised footprint. The current programme is designed to define the geometry, continuity and scale potential of multiple sub-parallel, structurally controlled mineralised zones, while also exploring for new unrecognised targets across underexplored areas of the Project. The survey forms part of a systematic exploration workflow that integrates geophysics with ongoing field mapping and sampling, with the objective of rapidly generating a pipeline of high-quality, drill-ready targets. The results of the ground magnetics programme will be integrated with the structural targeting work currently being undertaken by Lithosquare, enabling a multi-disciplinary approach to target refinement and prioritisation. The survey is designed to define the along-strike continuity of multiple sub-parallel, linear copper-bearing fault breccias, which individually outcrop discontinuously over a strike length of up to 0.9 km. The programme also targets the identification of additional prospective structures that may be hidden beneath the surface. The programme is being conducted by an independent geophysical contractor using a GEM GSM-19 Overhauser magnetometer, with the following parameters: 60 lines for a total of 111 line km. Average line length - 1.85 km. 100 m line spacing. Three contiguous grids covering a total of 11.20 km2. Estimated a two-week timeframe for data acquisition. Modelling, interpretation and reporting are estimated at 4 weeks. Based on the results of the ground magnetics survey, the Company intends to: Define priority target areas for follow-up work. Undertake detailed geological mapping and trenching. Undertake an Induced Polarisation (IP) /resistivity survey over priority targets. Advance a ranked pipeline of drill-ready targets. Aterian holds a 100% interest in the 50.4 km² Agdz Copper-Silver Project, comprising the 34.5 km² Agdz licence and the adjacent 15.9 km² Agdz Est licence in central Morocco. The Project is located in the highly prospective Anti-Atlas Mountains within the Drâa Tafilalet region, approximately 35 km east of Ouarzazate, a well-serviced regional hub with an airport and established infrastructure. The Project benefits from excellent access via paved and unpaved roads. It is situated approximately 40 km southeast of the Noor solar power complex, one of the world's largest renewable energy facilities. Agdz is located within Morocco's highly prospective Anti-Atlas belt, a stable and well-established mining jurisdiction with growing strategic importance for copper supply. The Agdz Project is situated within a well-established copper-silver mining district, approximately 14 km southwest of the Bouskour copper-silver mine (19 Mt at 1.44% Cu and 12 g/t Ag Measured & Indicated and 9 Mt at 1.61% Cu Proven & Probable) and within trucking distance of existing mining infrastructure. The world-class Imiter silver mine (192 M Oz Ag Measured & Indicated and 152 M Oz Ag Proven & Probable) lies approximately 80 km northeast of the Project, with both operations owned by Managem Group. While mineralisation at neighbouring deposits is not necessarily indicative of mineralisation at Agdz, their presence underscores the district-scale prospectivity of the Anti-Atlas Belt.
