View News Release in PDF

Abidjan, April 8, 2019 - Endeavour Mining Corporation (TSX:EDV)(OTCQX:EDVMF) is pleased to announce commercial production of its Ity CIL project, in Côte d'Ivoire, at its full nameplate capacity following a quick ramp up phase.

Sébastien de Montessus, President & CEO, stated: "I would like to congratulate the entire team for their hard work in helping us achieve this major accomplishment for Endeavour.

Achieving commercial production at the Ity CIL project marks a transformational moment in our history and an inflection point as we significantly increase our free cash flow capabilities."

The Ity CIL project began processing ore on February 20, 2019 and achieved its first gold pour on March 19, 2019. Its performance trial testing was recently successfully completed with all key metrics meeting prescribed targets: processing rate exceeding 11,100 tonnes per day, overall plant availability of 96%, and gold recovery rate of 94%.

Ity is expected to produce 160-200koz in 2019 at an AISC of $525-590/oz, with the bottom-end of the production guidance corresponding to the 4Mtpa nameplate capacity while the top-end already factored in upsides such as an earlier start date, an expedited ramp-up and the plant producing above its nameplate.
