Endeavour Mining Completes Upsize of Ity CIL Plant and Consolidates the Ity Mine Trend

ENDEAVOUR COMPLETES UPSIZE OF ITY CIL PLANT AND CONSOLIDATES THE ITY MINE TREND

HIGHLIGHTS:                                                  

CIL Plant Upsize

·CIL plant capacity increased by 25%, from 4Mtpa to 5Mtpa, completed on budget and on schedule

·The plant has achieved an annualized throughput exceeding 5Mtpa for the past two weeks

Ity Trend Consolidation

·Successfully consolidated the full 125km trend along the Ity Birimian belt with the acquisition of the Mahapleu tenement

·The Mahapleu tenement hosts an intrusive anomaly which has the potential to be similar in type and size to the one occurring at the Ity mine complex  

·The Mahapleu tenement is now one of the highly ranked greenfield exploration licenses within Endeavour’s portfolio; ground surveys expected to be initiated in early 2020

Abidjan, November 21, 2019 – Endeavour Mining (TSX:EDV) (OTCQX:EDVMF) is pleased to announce the successful completion of the 25% volumetric upgrade of the carbon-in-leach (“CIL”) plant, from 4Mtpa to 5Mtpa, at its Ity mine in Côte d’Ivoire. The Company is also pleased to announce that it has obtained the highly prospective Mahapleu tenement, resulting in Endeavour now controlling the entire Birimian greenstone trend that stretches 125km along the Ity mine.

Sébastien de Montessus, President and CEO, commented: “Building Ity on time and on budget has been a key achievement for 2019. With the plant upsize now complete, we are well positioned for 2020 and beyond. We believe the increased plant capacity will help accelerate the value created through exploration.”  

Patrick Bouisset, Executive Vice President Exploration and Growth added: “We are very excited to have consolidated control of the entire 125km Birimian corridor along the Ity mine. The Mahapleu tenement is a highly prospective area which remains unexplored despite being located within proximity to the Ity mine. With our primary exploration objective of extending mine lives beyond 10 years for both Houndé and Ity well on track, we can now focus on increasing our greenfield exploration efforts in Côte d’Ivoire with Mahapleu ranking high within our large greenfield portfolio, alongside Fetekro.”

PLANT UPSIZE

Following the commissioning of the 4Mtpa plant in April 2019, Endeavour launched optimization and de-bottlenecking work to increase the plant capacity by 25% to 5Mtpa for a minimal cost of between $10-15 million. Integration of components to achieve the increased throughput was carried out during the scheduled maintenance downtime with the plant achieving an annualized throughput exceeding 5Mtpa for the last two weeks.

As part of the volumetric upgrade, capacity of the following items was increased: variable speed drives for the primary apron feeder, vibrating grizzly, and lime screw feeder, tailings pumping and decant return, high pressure gland water supply, tailings pumping and a second 50t capacity oxygen plant. Upgrades to the tailings storage facility are ongoing.

ITY TREND CONSOLIDATION

The Mahapleu tenement was purchased for a minimal cash consideration and a royalty based on a sliding scale depending on the gold price (varying from 1% below $1,200/oz to 2.5% above $1,850/oz). Following this land consolidation, Endeavour now controls the whole extent of the Ity Birimian corridor that stretches nearly 125km, as shown in Figure 1 below.

An airborne Mag-VTEM survey was previously carried out on the Mahapleu tenement. The Mahapleu central area, known as Doui, appears to host a large intrusion which has the potential to be similar in type and size to the one associated with the large mineralization event that occurred at the Ity mine complex. Endeavour considers this area to rank high within its greenfield exploration portfolio and expects to initiate ground surveys in early 2020.
