Aterian plc Provides an Update on the Recently Completed Scout Reverse Circulation Drill Programme Conducted on Agdz Copper-Silver (Cu-Ag) Project in the Kingdom of Morocco
Aterian Plc provided an update on the recently completed scout reverse circulation (RC) drill programme conducted on the company's Agdz Copper-Silver (Cu-Ag) Project (Project) in the Kingdom of Morocco. The Project, which is 100% owned by the Company, covers 34.5 km2 and is located in Morocco's eastern Anti-Atlas Mountains. This scout RC programme consisted of 13 holes, between 20 m and 125 m downhole depth, totalling 1,080 m. The programme aimed to test the sub-surface below areas of known copper-silver mineralisation previously mapped on the surface and identified in reconnaissance channel samples. The programme also targeted several ground-based geophysical anomalies. The best intersections reported were 3 m grading 1.24 % Cu and 101 g/t Ag starting at a downhole depth of 8 m from a hole collared on the Makarn prospect and 6 m grading 0.79 % Cu and 5 g/t Ag starting from a downhole depth of 6 m collared on the Amzwaro prospect. The collar locations are widely spaced across approximately 8-10 km2 and were located to test several geological areas of interest and geophysical anomalies. The drill programme was designed with the following objectives: To intersect mineralisation of a suitable grade and width to be deemed as showing economic potential. To understand the down-dip continuity of the copper-silver mineralisation mapped and sampled at the surface within outcropping alteration zones. To provide geological and geochemical datasets to aid in defining a deposit-scale model. To provide geological and geochemical datasets with which to aid in the interpretation of geophysical anomalies. Geophysical targets were defined from a previously completed 137-line-km IP gradient array and a 12-line high-resolution IP survey, which were interpreted together with the ground magnetic survey data. 24AGRC-003: Amzwaro Prospect: Drill hole targets surface mineralisation and geophysical conductors. Copper mineralisation is locally associated with a visible pyrite-magnetite-specular haematite alteration assemblage. Alteration assemblages within 24AGRC-003 include: From 28 m to 112 m (84 m down-hole interval), specular haematite +/- magnetite, K-feldspar and carbonate as disseminations and veinlets.

Malachite and chalcocite, veinlets and disseminations are locally associated with chlorite, K-feldspar, and specular haematite alteration. Alteration assemblages within 24AGRC-006 include: From 2 m to 35 m (33 m down-hole interval), chlorite and K-feldspar, specular haematite, and trace epidote as veinlets, fracture coatings and disseminations. Alteration assemblages within 24 AGRC-005 include: From 2 m to 57 m (55 m down-hole interval), pervasive and fracture coating chlorite +/- k-feldspar, specular haematite, carbonate and trace epidote as fracture coatings, veinlets and disseminations. From 57 m to 70 m (13 m down-hole interval), K-feldspar and/or epidote and/or haematite as veinlets and disseminations. 24AGRC-010: Makarn Prospect - South Area- Drill hole targets surface mineralisation within conglomerate on the periphery of a conductive geophysical anomaly. Copper mineralisation is locally associated with a visible pyrite-chlorite alteration assemblage within conglomerate and dolerite dykes. Alteration assemblages include: From 34 m to 43 m (10 m down-hole interval), pyrite as fracture coatings and disseminations. From 66 m to 74 m (8 m down-hole interval), pyrite as fracture coatings and disseminations. From 1 m to 90 m (89 m down-hole interval), chlorite +/- K-feldspar, quartz specular haematite as disseminations, fracture coatings and veinlets. 24AGRC-011: Daoud Prospect: The drill hole targets surface mineralisation and extensive alteration within felsic to intermediate volcanic units and intermediate intrusives. Copper mineralisation is locally associated with a pyrite-chlorite alteration assemblage at the contact between an intermediate volcanic and intermediate intrusive. Alteration assemblages include: From 43 to 53 m (10 m down-hole interval), pervasive and fracture coating chlorite, pyrite and K-feldspar +/- quartz and carbonate as veinlets. From surface to 65 m (65 m down-hole interval), chlorite and K-feldspar +/- carbonate, quartz as fracture coatings and veinlets and disseminated haematite. 24AGRC-012: Daoud Prospect: The drill hole targets surface mineralisation and extensive alteration within felsic to intermediate volcanic units and intermediate intrusive. Copper mineralisation is locally associated with a pyrite-chlorite alteration assemblage at the contact between an intermediate volcanic and intermediate intrusive. Alteration assemblages include: From 16 to 20 m (4 m down-hole interval), pervasive and fracture coating chlorite, pyrite and K-feldspar +/- quartz and carbonate as veinlets.

Hole 24AGRC-004 returned no significant alteration zones and may have been drilled sub-parallel to mineralisation.
