Board Changes

As announced by the Company on April 30, 2026 in respect of an anticipated change of Chairman as part of the Board’s succession plan, Mr Kelly stood down as Chairman and Mr Ndlovu was duly appointed by the Board as Chairman immediately following the AGM.

The Company also announces that Nick Clarke did not stand for re-election as a director at the AGM and therefore left the Board with effect from the AGM.

Mr Clarke has made a valuable contribution to Caledonia during his time on the Board, bringing extensive technical expertise and industry experience, and providing insight and guidance as the Company continued to deliver at Blanket Mine and advance its growth strategy.

July Ndlovu, Chairman of Caledonia, said:

“On behalf of the Board and managementteam, I would like to thank Nick for his significant contribution to Caledonia since he joined the Board in 2019. His depth of miningexperience and technical knowledge have been greatly valued, and his advice and support have been important to the Company over a numberof years. We wish him all the very best for the future.”

The full text of each resolution proposed at the AGM, together with explanatory notes, are set out in the notice of AGM and management information circular dated March 26, 2026 which are available on the Company's website at:
