ENDEAVOUR APPOINTS CORPORATE BROKERS AHEAD
OF ITS LONDON STOCK EXCHANGE LISTING ON JUNE 14

London, June 9, 2021 – Endeavour Mining (TSX: EDV) (OTCQX: EDVMF), which expects to become the largest pure Gold producer listed on the Premium Segment of the London Stock Exchange ("LSE”), is pleased to announce the appointment of its sponsor and joint corporate brokers ahead of admission of its ordinary shares to the premium listing segment of the Official List, and to trading on the main market of the LSE ("Admission”).

Endeavour has appointed Barclays Bank PLC ("Barclays”) to act as its sponsor for the Admission, and, in conjunction with Morgan Stanley & Co. International plc ("Morgan Stanley”), to act as Endeavour’s joint corporate brokers thereafter. Joh. Berenberg, Gossler & Co KG ("Berenberg”) and Stifel Nicolaus Europe Limited ("Stifel”) have also been appointed to act as Endeavour’s UK & European broking advisers to further assist in raising its capital markets profile. The appointed corporate brokers and UK & European broking advisers will seek to facilitate market making on the LSE as Endeavour is not intending to raise capital in conjunction with its listing.

It is expected that Admission will occur at 8:00 am BST on June, 14, 2021. Shares will trade on both the TSX and LSE under the ticker symbol "EDV”.
