Caledonia Mining Corporation Plc: Leigh Wilson Retires as Director and Non-Executive Chairman

ST HELIER, Jersey, May 05, 2023 (GLOBE NEWSWIRE) -- Caledonia Mining Corporation Plc (NYSE AMERICAN, AIM and VFEX: CMCL) ("Caledonia" or the "Company") announces that yesterday Leigh Wilson retired from his role as Director and Non-Executive Chairman of the Company. His successor as Chairman will be announced after the upcoming annual general meeting to be held on May 9, 2023, with John Kelly, Non-Executive Director, acting as interim Chairman in the intervening period.

 Commenting on Leigh Wilson’s retirement, Mark Learmonth Chief Executive Officer, said:

"On behalf of Caledonia's board of directors, I thank Leigh for his contribution to Caledonia. Leigh became Chairman in May 2013, after a successful career in international business and financial services having served in senior executive and management positions with Union Bank of Switzerland in London, and with Paribas Group in Paris and New York, where he served as CEO of Paribas North America.

"Caledonia was a very different company when Leigh became Chairman and, over this time, he has made many contributions to its success. Under his leadership, Caledonia has increased production from approximately 45,000 ounces in 2013 to just over 80,000 ounces in 2022. A key component of this growth was the completion of the Central Shaft project which has established a solid foundation for its growth.

"Over the last 18 months, Caledonia has acquired an attractive portfolio of high-quality exploration and development assets in Zimbabwe. We now have a clear pathway to build on the success at Blanket Mine with the objective of creating a multi-asset, mid-tier, Zimbabwe-focused gold producer over the course of the next 5 to 7 years.

"Achievements such as this require strong leadership: management and the Board are extremely grateful to Leigh, where his strength, skills and experience proved invaluable over this period.

"Caledonia has also improved its relevance to international capital markets, with Caledonia shares now traded on the NYSE American, AIM in London and the Victoria Falls Stock Exchange in Zimbabwe. Caledonia's share price has been one of the top performers in its peer group: since January 2013, Caledonia's market capitalisation has increased from $56 million to $278 million; over the same period, we have paid almost $30 million in dividends to Caledonia shareholders and total shareholder return over the period has been 670 per cent. An outstanding performance by any criteria.

"On behalf of the Board of Directors, the management team and our shareholders, I thank Leigh and wish him all the best in the future.”

Commenting on his retirement, Leigh Wilson said:

"It has been a privilege to serve Caledonia and its shareholders as a Director and Non-Executive Chairman over the last ten years. During this period, the business has been transformed from a junior gold miner with one producing asset to a company that has now laid the foundation to realise its vision of becoming a multi-asset, mid-tier, Zimbabwe-focused gold producer.

“The Directors, Executive Management of both Caledonia and Blanket Mine, and staff have worked hard to build and expand the business. It has been an honour to help guide them on this journey. As a shareholder, I will remain closely interested in Caledonia’s future and I have no doubt that the excellent team at Caledonia, Blanket and now Bilboes will continue to deliver on this strategy.”
