EIA Approval for Agdz Cu-Ag Project and Funding

Aterian plc (AIM: ATN), the Africa-focused critical metals exploration company, is pleased to announce the approval of it’s recently commissioned Environmental Impact Assessment (”EIA”) for the 100%-owned Agdz Mining Licence, part of the Agdz (“Cu-Ag“) Project (“Agdz” or the “Project“) in the Kingdom of Morocco (“Morocco“).

In the current global mining environment, the approval of the EIA represents a major regulatory milestone and materially de-risks the Project as Aterian advances toward systematic drilling and development readiness.

Highlights:

• Environmental Impact Assessment plan approved at the Agdz Cu-Ag Project.
• The Regional Centre of Investment of Errachidia approval represents a key milestone and allows for further project advancement.
• Confirms strong local, regional and national stakeholder support.
• Material regulatory de-risking of the Agdz Project in a tightening global permitting environment.
• Previous drilling has confirmed shallow Cu-Ag mineralisation across multiple prospects, including:
  • 1.24 % Cu with 101 g/t Ag over 3 m from 8 m (downhole) – Makarn (North) prospect
  • 0.45 % Cu with 3 g/t Ag over 11 m from 32 m (downhole) – Makarn (South) prospect
  • 0.79 % Cu with 5 g/t Ag over 6 m from 6 m (downhole) – Amzwaro prospect
• £100,000 raised from existing shareholders to fund project advancement toward development readiness.

Charles Bray, Chairman of Aterian, commented:

“Securing Moroccan EIA approval for the Agdz Mining Licence is a major step forward for Aterian. In a tightening global permitting environment, being regulatorily cleared to advance a copper project is a significant competitive advantage.

Our focus now shifts decisively to drilling for scale to develop this asset. The objective is clear: expand the mineralised footprint, build toward a defined resource base, and position Agdz as a development-ready copper asset in a jurisdiction with strong infrastructure and mining heritage. The integration of AI-driven geological modelling, through our partnership with Lithosquare, strengthens our targeting capability and enhances capital efficiency as we move into the next drilling phase.

With copper demand structurally rising and permitted projects increasingly scarce, Agdz represents a compelling opportunity. We are especially pleased to hear from existing shareholders seeking to participate in the recent equity placing, allowing the Company to allocate for expenditure to deliver sustained drilling news flow as we advance the Project over 2026.”

Strategic Importance

Permitted copper projects are increasingly scarce globally. With demand driven by electrification and the energy transition, projects capable of advancing without regulatory uncertainty are becoming strategically important.

EIA approval significantly strengthens Agdz’s development pathway and enhances its attractiveness to investors and potential strategic partners. The integration of AI-driven geological modelling through Lithosquare further positions Aterian to deploy capital…
