ENDEAVOUR ANNOUNCES CEO TERMINATION

The board of directors of Endeavour Mining PLC has terminated the president and chief executive officer, Sebastien de Montessus, for serious misconduct with immediate effect. This follows an investigation by the board into an irregular payment instruction issued by him in relation to an asset disposal undertaken by the company. The amount of this irregular payment instruction is $5.9-million (U.S.). The board recently became aware of this in the course of a review of acquisitions and disposals, which is continuing. Mr. de Montessus has been removed from the company's board of directors with immediate effect.

Separately, in October, 2023, allegations were made against Mr. de Montessus through the company's confidential whistle-blowing channel relating to his personal conduct with colleagues. Following a recent external investigation, the board had received the findings and, at the point of termination, was considering the appropriate course of action.

The board has appointed Ian Cockerill (currently deputy chair of the board) as chief executive officer and executive director with immediate effect.

Mr. Cockerill has over four decades of experience in the global natural resources industry. During his career, he has held senior roles covering operational, project and executive positions around the world, having held executive roles at major international mining companies, including chief executive officer of Gold Fields and Anglo Coal, a subsidiary of Anglo American, as well as non-executive positions. Mr. Cockerill will be reviewing his other current directorships in light of his appointment as chief executive officer and executive director of Endeavour.

Remuneration

Full details of the impact of the termination of Mr. de Montessus on his remuneration will be disclosed on the company's website in due course in compliance with Section 430(2B) of the Companies Act 2006 and in the director remuneration report within the annual report and accounts for the year ended Dec. 31, 2023, and subsequent years, as appropriate.

Mr. Cockerill will be paid in accordance with the approved director remuneration policy. Full details of his remuneration terms will be disclosed in the company's 2023 annual report.
