ZAMBIA LEGAL UPDATE

Arc is pleased to provide an update on certain of the legal cases being progressed in Zambia.

On 17 November 2025, the High Court in Zambia set aside in full a previously entered consent judgement which transferred a portion of an exploration license, legally owned by Handa Ltd, to Lunda Resources Ltd (the "Affected Interest"). The Affected Interest is not considered a material part of Arc Mineral's portfolio.

The ruling followed a successful challenge by Arc and its co-plaintiffs on the basis that the consent judgement had been entered into without their involvement as the shareholders of Handa and contrary to principles of natural justice.

This is a positive legal outcome for the Company in removing what the Company considers to have been an irregularly obtained consent judgement through overreach by a provisional receiver, whose appointment has since been stayed (see announcement dated 15 August 2025).

Further updates will be provided as appropriate.

Nick von Schirnding, executive chairman of Arc, commented:

"The setting aside of a judgement to transfer a portion of one of our licenses represents a major step forward for Arc as we deal with a former shareholder's vexatious attempts to disrupt our exploration activities. It is of great comfort that we operate in a jurisidiction where a strong judiciary and adherence to the rule of law prevails."
