George Town, December 24, 2018 - Endeavour Mining (TSX:EDV OTCQX: EDVMF) ("Endeavour") is pleased to announce that on December 24, 2018, it completed the sale of its interest in the non-core Tabakoto mine to Algom Resources Limited, a subsidiary of BCM International Ltd ("BCM"), as previously announced on September 4, 2018.

ABOUT ENDEAVOUR MINING CORPORATION

Endeavour Mining is a TSX listed intermediate African gold producer with a solid track record of operational excellence, project development and exploration in the highly prospective Birimian greenstone belt in West Africa. Endeavour is focused on offering both near-term and long-term growth opportunities with its project pipeline and its exploration strategy, while generating immediate cash flow from its operations.

Endeavour operates 5 mines across Côte d'Ivoire (Agbaou and Ity), Burkina Faso (Houndé, Karma), and Mali (Tabakoto) which are expected to produce 670-720koz in 2018 at an AISC of $840-890/oz. Endeavour's high-quality development projects (recently commissioned Houndé, Ity CIL and Kalana) have the combined potential to deliver an additional 600koz per year at an AISC well below $700/oz between 2018 and 2020. In addition, its exploration program aims to discover 10-15Moz of gold between 2017 and 2021 which represents more than twice the reserve depletion during the period.
