Endeavour Mining's Ity CIL Project Construction is Tracking Ahead of Schedule and On-Budget

Sébastien de Montessus, President & CEO, stated: "I'd like to thank the construction team for their hard work and excellent progress achieved so far. Completing the construction sooner is expected to result in material improvement to our 2019 free-cash flow generation potential as Ity CIL will be a low-cost operation with AISC expected to be below $500/oz over its first 5 years."

Jeremy Langford, COO & Executive Vice-President Projects added: "The experience that our in-house construction team has gained from our previous builds in the region, the early installation of the Ball and SAG mills, combined with the excellent progress made during the rainy season, have been key factors which have helped advance the Ity CIL construction ahead of schedule. We are also particularly pleased with the continued strong safety track record with zero lost-time incidents to date."

KEY MILESTONES ACHIEVED TO DATE INCLUDE:

• More than 6 million man-hours worked with zero lost-time injuries.
• Overall project completion stands at over 75%, tracking approximately 2 months ahead of schedule. 
• Nearly all of the $412 million initial capital cost has been committed and approximately 65% has been spent (inclusive of drawn equipment financing).
• The process plant construction is over 70% complete, tracking ahead of schedule as the Ball and SAG mill installation commenced three months earlier than initially planned. Structural, mechanical, piping and electrical installation work is well underway.

ABOUT THE ITY CIL PROJECT

The Ity CIL project commenced construction in September 2017, and is being carried out by Endeavour's in-house team following their successful completion of the Houndé and Agbaou constructions. The Optimized study, published in September 2017, demonstrated the significant potential for Ity, which has already been in operation for more than 20 years, to become another flagship asset for Endeavour. The Ity CIL project is expected to produce approximately 204,000 ounces annually for the first 10 years, at a low AISC of $549/oz with robust economics which includes an after-tax NPV5% of $710m based on a gold price of $1,250/oz.

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.
