Directorate Change

Arc Minerals (LSE:ARCM) announces that Mr Valentine Chitalu has resigned from the Board of the Company with effect from today, 30 July 2025. In recent months, Mr Chitalu's commitments to his other interests have increased significantly, and he no longer believes he can devote sufficient time to fulfil his responsibilities to Arc.

Valentine Chitalu commented:

"I have been privileged to be part of the Arc Minerals team and to contribute to the company's exploration activities in Zambia and Botswana. I am proud of the work that we have accomplished together and look forward to following Arc's developments going forward."

Nick von Schirnding, Executive Chairman, commented:

"I would like to thank Valentine for his time and sage advice over the last three and half years as a non-executive director and strategic advisor to Arc and we wish him all the best going forward. We have commenced discussions regarding other Zambian candidates to replace Valentine as a non-executive director."
