Aterian plc update on its 100% owned Agdz copper and silver project in the Kingdom of Morocco. The Company has undertaken a review of an induced polarisation ("IP") gradient array and high-resolution IP ("HIRIP") geophysical survey. The survey was completed on the northern part of the Project in preparation for scout drilling to be executed on the Project.

The review has indicated several high-priority anomalies and increased the target area due for further exploration. The Company recently acquired Agdz as part of a portfolio of 15 prospective copper-silver and base metal projects covering an area of 762 km2 in Morocco. Agdz Highlights: Agdz hosts four significant Cu-Ag prospects covering an area of approximately 8 km2: The 2.80 km long Makarn prospect, with results up to 8.00 % Cu and 448 g/t Ag; The 2.00 km long Amzwaro prospect, with results up to 4.82 % Cu and 189 g/t Ag; The 0.15 km long Minière prospect, with results up to 13.05 % Cu and 12 g/t Ag; The 0.70 km long Daoud prospect, with results up to 2.71 % Cu, 152 g/t Ag; 137 line-km IP gradient array survey completed over an area of 14 km2.

12 High-Resolution IP ("HIRIP") profiles completed to acquire 2-D resistivity and chargeability depth sections to depths of c.250 m. Several new geophysical anomalies identified. Surveying key geological structures and outlining potential mineralised targets for follow-up. Previously reported assay results from a limited reconnaissance trenching exercise included 0.65 % Cu and 36.54 g/t Ag over 14.12 m and 0.36 % Cu and 13.26 g/t Ag over 13.70 m. Agdz is located 14 km southwest of the Bouskour Cu-Ag mine.
