Zimplats keeps leadership continuity as Segula succeeds Mhembere

Mhembere steps down after 19 years at Zimplats

Zimplats Holdings Limited (ASX:ZIM) is changing chief executives at a significant point in its operating history, with Alexander Mhembere retiring from the role after 19 years. His departure takes effect on 1 November 2026, Zimbabwean time, and includes his retirement as an executive director.

Mhembere will not disappear from the business entirely. He will remain chairman of Zimbabwe Platinum Mines, Zimplats’ operating subsidiary, giving the company a continuing link to his institutional knowledge and preserving a governance role within the Zimbabwean operations.

Internal successor takes charge of expanded mining platform

The board has appointed Dr Stanley John Segula as CEO from the same date. Segula has served as managing director of Zimbabwe Platinum Mines since May 2015 and previously held senior roles including chief operating officer and group executive for mining.

That internal succession matters because Zimplats’ investment programme has reshaped the company well beyond its early open-pit mining origins. The company says Mhembere oversaw a US$1.8 billion strategic programme covering mine replacement and development, expanded concentrator capacity and the upgraded Selous smelter, which tripled smelting capacity. Zimplats has also commissioned a 35MW solar plant at Selous as the first phase of a planned 185MW renewable energy programme, following the broader solar expansion programme reported as remaining on track earlier this year.

Segula inherits strategy without an announced reset

Segula brings more than 30 years of mining leadership experience and qualifications spanning mining engineering, strategic management and mine management. The announcement presents his appointment as an orderly transition and says his experience within Zimplats will support continuity in the group’s strategic direction.

The filing does not announce a change to production plans, capital allocation, remuneration or financial guidance. That leaves the immediate investment question less about a new strategy than about execution: whether Segula maintains momentum across underground mining, processing, smelting and renewable infrastructure while the leadership change settles in.
