ENDEAVOUR ANNOUNCES RESULTS OF SHAREHOLDER MEETINGS
AND BOARD APPOINTMENT

George Town, 25 May 2021 - Endeavour Mining Corporation (TSX: EDV) (OTCQX: EDVMF) is pleased to announce that all resolutions at today's Annual General Meeting and Court and Extraordinary General Meetings, with regards to the proposed listing on the premium segment of the Official List of the FCA and admission to trading on the London Stock Exchange ("Admission"), were duly passed.

As such, Endeavour remains on track to list on the London Stock Exchange ("LSE") on or about June 14, 2021. Endeavour is not intending to raise capital in conjunction with its London listing and will be retaining its listing on the Toronto Stock Exchange ("TSX"). Shares will trade on both exchanges under the ticker symbol "EDV".

Michael Beckett, Chairman of the Board of Directors, said: "The strong support received for today's resolutions demonstrates that shareholders share the Board's view of the benefits that are expected to result from our listing on the premium segment of the London Stock Exchange. This is an important strategic milestone in the Company's evolution as it will provide deeper access to a diverse pool of investor capital with a strong understanding of its key operating jurisdictions across West Africa. We also envisage increased demand due to the expected inclusion in the FTSE UK Index Series and MSCI Europe Index."

Endeavour is also pleased to announce the appointment of Dr. Carmen Letton to the Board as an independent non-executive director. Dr. Letton's appointment adds greater technical depth to the Board, as she brings 35 years of experience in the mining industry. Endeavour's Board is now composed of ten members: Chairman Michael Beckett, James Askew, Alison Baker, Sofia Bianchi, Carmen Letton, Livia Mahler, David Mimran, Naguib Sawiris and Tertius Zongo as non-executive directors, and Sébastien de Montessus as executive director, President and CEO.

Michael Beckett commented:"I want to welcome Carmen to the Board and look forward to drawing on her considerable expertise as Endeavour seeks to continue its momentum as a senior gold producer over the coming years. In addition, I'd like to sincerely thank both Bill Biggar and Frank Wheatley for their contributions during the integration period of the Teranga assets. Both have decided not to stand for re-election tohelp us facilitate are-balancingof the Board composition to meet UK corporate governance best practice as an element of our listing on the London Stock Exchange. The Board recognizes their strong contributions to the success of Teranga and wishes them well in the future."

The Court Meeting and an Extraordinary General Meeting were held alongside the Annual General Meeting to seek shareholder approval for the establishment of a new UK-incorporated parent company for the Endeavour group pursuant to a scheme of arrangement (the "Scheme"). This new parent company is intended to promote enhanced governance as Endeavour completes its LSE listing and anticipates inclusion in the FTSE UK Index Series.

Implementation of the Scheme remains subject to the satisfaction or waiver of the other conditions set out in the scheme circular dated April 23, 2021, including (but not limited to) the approval of the Scheme by the Cayman Islands Court at the sanction hearing scheduled for June 9, 2021. Subject to the satisfaction or waiver of those conditions, the Scheme is expected to become effective on June 11, 2021, with Admission expected on or about June 14, 2021. In connection with the applications for Admission, Endeavour will also publish a prospectus in the UK (the "Prospectus"). The Prospectus will be published upon receipt of approval by the FCA, which is expected to occur on or about June 9, 2021.

To facilitate the settlement of outstanding trades in shares in Endeavour Mining Corporation, trading in the shares of Endeavour Mining plc is expected to commence on the TSX at 9:30 am (Toronto time) on 16 June 2021. Trading in the shares of Endeavour Mining Corporation will continue on the TSX until such time.
