Multi-Billion Dollar Company Terminates CEO

The Board of Directors of Endeavour Mining plc (LSE:EDV, TSX:EDV, OTCQX:EDVMF) (“Endeavour”, the “Group” or the “Company”) today announces the termination of the President and Chief Executive Officer, Sébastien 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 US$5.9 million. The Board recently became aware of this in the course of a review of acquisitions and disposals, which is ongoing. Sébastien de Montessus has been removed from the Company’s Board of Directors with immediate effect.

Separately, in October 2023 allegations were made against Sébastien de Montessus through the Company’s confidential whistleblowing 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.

Remuneration

Full details of the impact of the termination of Sébastien 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 Directors' Remuneration Report within the Annual Report and Accounts for the year ended 31 December 2023, and subsequent years, as appropriate.

Note: Copper equivalent grades (CuEq) are for comparative purposes only. Mo, Cu and Ag values are uncut, and core recovery is assumed to be 100% for the entire drilled length of A23-013 except for intervals from 0.00m to 33.00m and 484.00m to 498.00m where core recovery was below 50% due to leaching and faulting. The project is at an early stage of exploration and conceptual recoveries of Cu 85%, Mo 82%, and Ag 75% are assigned to the CuEq calculations. Conversion of metals to an equivalent copper grade based on these metal prices is relative to the copper price per unit mass factored by conceptual recoveries for those metals normalized to the conceptualized copper recovery. The metal equivalencies for each metal are added to the copper grade. The formula for this is: CuEq % = Cu% + (Mo% (Mo recovery / Cu recovery) (Mo $ per lb / Cu $ per lb) + (Ag g/t (Ag recovery / Cu recovery) (Ag $ per oz/ 31.1034768) / (Cu $ per lb 22.04623)).

*Copper equivalent calculations use metal prices of Cu - US$3.34/lb, Mo - US$18/lb and Ag - US$21.87/oz.
