Copper-Silver Structures Identified at Agdz Est
Aterian plc has announced encouraging surface sampling results from its Agdz Est Copper-Silver Project in Morocco, identifying multiple mineralised fault zones extending the known footprint of mineralisation across the 50.4 km² project area. These results, which confirm a structurally controlled mineral system with mineralisation found in only approximately 10% of the project area, include grades such as 1.39% Cu from a 2m wide breccia zone and 2.97% Cu with 51 g/t Ag from a float sample. The company plans follow-up ground magnetic surveys and trenching to test continuity and scale, with the data to be integrated with Lithosquare's AI platform to accelerate drill evaluation and advance Agdz towards becoming a flagship development opportunity.

[{"type":"text","content":"\n\n29 January 2026\n \nAterian plc\n(\"Aterian\" or the \"Company\" or the \"Group\")\n \nMultiple Copper-Silver Mineralised Structures Identified, Agdz Est Project, Morocco\n \nAterian plc (AIM: ATN), the Africa-focused critical metals exploration company, is pleased to announce encouraging surface sampling results from its 100%-owned Agdz Est Copper-Silver (\"Cu-Ag\") Project (\"Agdz Est\" or the \"Project\") in the Kingdom of Morocco (\"Morocco\").\n \nThe results identify multiple mineralised fault zones hosting copper and silver, significantly extending the known footprint of mineralisation within the broader 50.4 km² Agdz Project (\"Agdz\") area. The identification of these multiple mineralised structures over a limited area highlights the potential scale of the system and materially enhances the Company's confidence in advancing Agdz towards drill evaluation.\nHighlights:\n· Multiple copper-silver mineralised fault zones identified, confirming a structurally controlled mineral system.\n· Mineralisation confirmed from only c.10% of the Agdz Est Project, highlighting significant exploration upside.\n· Four sub-parallel structures mapped over strike lengths of up to 0.9 km, with apparent widths of up to 7 metres, and open along strike.\n· Mineralised zones are spaced 300 to 400m apart, and commonly covered with a thin soil and rock float.\n· Encouraging copper and silver grades returned from early-stage surface sampling, including:\no 1.39 % Cu from a 2 m wide breccia zone\no 0.51 % Cu with 7 g/t Ag from a 3 x 2 m outcrop of silicified granite\no 2.97 % Cu with 51 g/t Ag from float sample\no 1.34 % Cu with 31 g/t Ag from a fractured zone of 4 m apparent width within granite\n· Follow-up ground magnetic and trenching planned to test continuity, scale and structural controls on mineralisation.\n \nStrategic Significance\nThese results support the interpretation that Agdz Est forms part of a broader, district-scale copper-silver system, with multiple mineralised structures developed within a favourable geological setting.\n \nWith mineralisation confirmed to date over a limited area, the Company b...
