About Metals One

Metals One is developing strategic battery metals projects in Finland (Black Schist Project) and Norway (SRH Råna Project), with approximately £9 million of exploration carry exposure through a farm-in agreement. Metals One is aiming to help meet the significant critical minerals by defining resources on the doorstep of Europe's major electric vehicle OEMs and battery manufacturers. Metals One's Black Schist Project in Finland, totalling 706 km² across three licence areas, has an Inferred Resource of 28.1 Mt nickel-zinc-copper-cobalt and is located adjacent to Talvivaara, Europe's largest operating nickel mine. Metals One's fully carried SRH Råna Project in Norway covers 18.14 km² across three contiguous exploration licences, with significant opportunity for brownfield exploration of the Råna intrusion, and proven potential for massive sulphide nickel-cobalt-copper mineralisation.
