Aterian Plc announced the results, including 2.34 % copper ("Cu") and 33.3 g/t silver ("Ag"), from geological reconnaissance work completed on the Company's Zaer Project (the "Project"). The Project covers 96 km2 and is located 70 km south of Rabat and 80km east of Casablanca within the Rabat-Sale-Kenitra and the Casablanca-Settat regions of the Kingdom of Morocco (" Morocco"). The Project is one of 17 copper, silver and base metal projects owned by Aterian, covering 897 km2 in Morocco within established current and historic mining districts.

Highlights: Sampling reports up to 2.34 % Cu and 33.3g/t Ag. Project hosts several historically mapped copper occurrences. Situated on the margins of the Hercynian-age granitic Zaer intrusive complex.

Reconnaissance rock chip and stream sediment sampling completed. Several stream sediment geochemical anomalies for follow-up work. The region hosts numerous active and historic mines and development projects for copper, tin, tungsten, lead, zinc and fluorite.

Nearby operations include ONHYM's Rhouirat N'Has tungsten-copper project and the Sokhret Allal tin-tungsten deposit, with active projects elsewhere in the region, including Managem's El Hamman fluorite mine and Atlantic Tin's tin development projects at Achmmach (22.2 Mt grading 0.70 % SnO2) and Bou El Jaj, where the mineralisation is reportedly hosted in veins, stockworks, skarns and greisens within granites and the surrounding metamorphic aureole on the western and northern margins. The host geology comprises highly foliated and contact-metamorphosed metasedimentary rocks, including quartzites, phyllites and schists that host several copper, lead, zinc, tungsten and tin occurrences. The Company holds a 100 % interest in the project.

Aterian Reconnaissance Exploration Results Reconnaissance has focussed on two areas within the project, with limited outcrop sampling over the northern licences and stream sediment sampling over the western block of three licences. Eleven rock chip samples (10 outcrop* and one surface float sample) have been collected from the northern licences. Three samples reported greater than 0.25 % Cu, with a maximum of 2.34 % Cu and 7.91 g/t Ag, reporting from a brecciated metasediment outcropping near a historic copper anomaly.

Two samples reported 0.4 % Cu and 0.29 % Cu from similar brecciated outcrops close to the mapped anomaly. A sample from a northeast trending quartz vein, up to 2m wide, reported 33.3 g/t Ag and 0.62% Pb.
