Board Changes

Sylvania (AIM: SLP), the platinum group metals ("PGM") and chrome producer and developer, with assets in South Africa, announces that Ms. Lewanne Carminati will be stepping down from the position of Chief Financial Officer ("CFO") and from the Board of Sylvania, to pursue personal development goals, with effect from 30 November 2025.

Following an external process, Sylvania is pleased to announce the promotion of Executive Officer Finance, Ms. Ronel Bosman, to the position of CFO, with effect from 1 December 2025. Ronel is a seasoned financial executive with over 20 years of experience, including more than 15 years in finance and leadership roles across sectors such as mining, facilities management and investment.

Ronel has been with Sylvania since 2021, and in her current role oversees the financial, treasury and tax functions for the South African subsidiaries, leading a team of 18 professionals. Her previous roles at Tsebo, Archer Daniels Midlands and Thebe Investments have further demonstrated her ability to manage complex financial operations, implement cost saving initiatives, and drive financial performance across diverse business environments. She has consistently delivered results by aligning financial strategies with business goals, streamlining reporting systems, and fostering high performing teams. She will join the Board of Directors ("Board") in due course.

Eileen Carr, Independent Non-Executive Chair of Sylvania, commented:

"I would like to thank Lewanne for everything she has done for Sylvania over the past 16 years, five of those as CFO. Her dedication, professionalism and leadership have been exemplary, and she will be sorely missed by everyone at the Company. Lewanne has greatly contributed to the ongoing success of the business and leaves us in a strong position, primed for further growth. On behalf of the Board, I wish her all the very best for the future.

"I would also like to congratulate Ronel on her new, richly-deserved role. Her financial expertise, operational insight, leadership skills and knowledge of the Company made her the standout candidate, and I have no doubt she'll be successful in the role."
