Aterian PLC - Operational Update

Aterian PLC provides an operational update on the Tata Sedimentary-Hosted Copper Project in Morocco. Additional copper discoveries have been made, extending mineralization within two stratigraphic horizons.

The project covers 138.6 km2 with a significant strike length of 32 km. Copper grades are considered economic, comparable to other renowned deposits. Future plans include further geological mapping, sampling, and geophysical surveys to aid in drill planning. The Tata Project offers a large-scale copper development opportunity with extensive strike length and economic grades. Recent fieldwork results show promising mineralization thicknesses and grade values. The company is proceeding with further exploration in a disciplined manner, anticipating the project will require more time.
