Changes in Board Composition Orion Minerals Limited Incorporated in the Commonwealth of Australia Australian Company Number 098 939 274 ASX share code: ORN JSE share code: ORN ISIN: AU000000ORN1 Changes in Board Composition During the past several months, Orion Minerals Limited (ASX/JSE: ORN) (Orion or the Company) has undertaken a review of its Board's growing responsibilities as the Company transitions into a development stage at its copper and copper zinc mines in the Northern Cape of South Africa. The Board review led to the recent appointments of experienced non-executive directors Anthony Lennox and Patience Mpofu (refer ASX/JSE release 13 December 2023). The current Board composition includes Mr Philip Kotze as a representative of Clover Alloys Copper Investments Pty Ltd (Clover Alloys), which is a 9.2% shareholder in Orion. Orion is progressing possible funding and transaction opportunities with multiple parties including Clover Alloys, in respect of the Company's various projects. As ongoing discussions with Clover Alloys could put Mr Philip Kotze in a conflicted position, the Orion Board, including Mr Kotze, have agreed that it would be preferable if Mr Kotze stepped down from the Orion Board. The Board has therefore today accepted Mr Kotze's resignation as a director of Orion with immediate effect. Orion Chairman, Denis Waddell commented: "We would like to thank Philip for his valuable contribution to the Orion Board over the past 10 months, which has assisted us to firm our early production plans at the Prieska Copper Zinc Mine and the Okiep Copper Project. We look forward to continuing our valued involvement with Mr Kotze and with Clover Alloys, who remain supportive shareholders." For and on behalf of the Board.
