Aterian Plc
("Aterian", the "Company" or the "Group")

Commencement of Work at Sua Pan Lithium Project

Aterian PLC (LSE: ATN), the critical minerals exploration and development
company, announces that it has commenced a groundwater reconnaissance and
brine sampling programme at its Sua Pan Lithium Project ("Project") in the
Republic of Botswana ("Botswana"). The programme is being undertaken through
the Company's 90% owned subsidiary, Atlantis Metals ("Atlantis").

The work will be completed by Aqualogic (Pty) Ltd, a Botswana-based
hydrogeology and geochemical consultancy with operational experience in the
Makgadikgadi Basin. The programme will consist of sampling from existing wells
and shallow auger locations within prospecting licences PL2621/2023,
PL2328/2023 and PL2338/2023, and will establish baseline hydrogeochemical
data, including lithium concentrations.

Work Programme Summary

·      Building a Project database and conceptual hydrochemical model;

·      Sampling of up to six existing brine wells alongside shallow
near-surface sampling points;

·      Field measurement of physicochemical parameters (pH, EC,
temperature, TDS);

·      Laboratory analysis of major ions and selected trace elements,
including lithium;

·      Hydrochemical interpretation and spatial assessment to identify
areas for follow-up exploration.

The programme is anticipated to be completed, dependent on weather conditions,
over the coming weeks, with laboratory results and interpretation to follow. A
technical report will be delivered to the Company, and its conclusions will be
used to define subsequent exploration steps.

Charles Bray, Chairman of Aterian, commented:

"The commencement of this programme marks a meaningful step forward in
advancing our exploration strategy in Botswana. The Sua Pan project sits
within a region known to host laterally extensive brine systems, and
establishing the presence and distribution of lithium and other minerals
within our licence areas is central to evaluating its strategic potential.
Aterian is building a portfolio focused on critical minerals required for the
energy transition, and this work forms part of that broader growth pathway. We
look forward to reviewing the results and updating shareholders as the
programme progresses."

Further updates will be provided as appropriate.
