Abidjan, February 20, 2019 - Endeavour Mining Corporation (TSX:EDV)(OTCQX:EDVMF) ("Endeavour") is pleased to announce that excellent progress continues to be made at its Ity CIL project in Côte d'Ivoire, as wet commissioning has commenced. Construction is progressing on-budget with over 97% of the total project complete and the first gold pour expected to occur two months ahead of schedule in early Q2-2019.

Sébastien de Montessus, President & CEO, stated: "We are proud of the key milestones achieved in recent months as the project construction has been significantly de-risked. We are excited to have commenced the commissioning phase several months ahead of the initial schedule and look forward to the first gold pour in early Q2-2019.

The start of production at Ity will be a transformative moment for Endeavour. It will become, alongside Houndé, our second flagship mine, and marks the end of several years of large capital-intensive projects which will allow us to focus on cash flow generation and generating returns on our capital employed.

With seven drill rigs currently operating in the Le Plaque area, we expect our additional exploration activity to further demonstrate the potential of Ity."

Key milestones achieved to date include:

• Over 8 million man-hours have been worked without a lost time injury.
• Overall project completion stands at more than 97%, tracking approximately two months ahead of schedule.
• The project remains on-budget with the remaining cash outflow for 2019 amounting to $50 - $60 million.
• Wet commissioning has commenced and, in preparation for production, ore is expected to be introduced into the process plant milling circuit in the coming days.
