Endeavour Mining takes Ity project to new heights

Construction is progressing on-time and on-budget at West African gold producer Endeavour Mining’s CIL plant at its Ity mine in Cote d’Ivoire, with the company having also released a maiden resource for its Le Plaque target – one of Ity’s most promising deposits.

Endeavour Mining has made good progress on the construction of the Ity CIL plant, having achieved a major milestone with the completion of the CIL tanks ring beam concrete pours. with the first gold pour expected mid-2019.

In addition, Endeavour Mining has reported a high-grade maiden mineral resource estimate for the central part of its Le Plaque discovery, located within 5 km of the future CIL plant.

The Le Plaque target, which covers an area of 4 km2, has the potential to be the next significant discovery following the company’s recent Daapleu and Bakatouo discoveries, and the maiden resource positions it to be amongst Ity’s highest grade deposits.

Only the central portion has been drilled to date, representing about 25% of the Le Plaque target, in an area named Le Plaque Main, for which a maiden mineral resource estimate has been delineated.

A new drilling campaign aimed at delineating the extensions and investigating other high-grade targets in proximity is planned for the remainder of 2018.

“The Le Plaque discovery continues to demonstrate the highly prospective nature of the Ity area. While we have only drilled a small portion of the target, its characteristics suggest it may have the potential to be the next significant discovery following the Daapleu, Mont Ity and Bakatouo discoveries,” says Endeavour Mining executive VP of Exploration and Growth Patrick Bouisset.

“In 2018, we look forward to continuing exploration at the entire Le Plaque target, and several other near-mill targets, with the aim of delineating additional extensions. We are equally excited about our increased greenfield exploration focus with drilling initiating on a number of targets within the wider 100 km Ity corridor which we fully control,” he adds.

Ity CIL project construction update

The main milestones achieved to date include:

  • No LTI with over 800 000 man-hours worked;
  • Nearly 50% of the total capital cost of US$412 million has already been committed;
  • Concrete works are tracking well, with all eight ring beams and the SAG mill foundation pour complete and ball mill foundation pour commencing;
  • Tailings storage facility (TSF) earthworks are progressing on schedule with 15% completed;
  • EPCM design is progressing on-schedule with approximately 50% completed; and
  • Design work for the 90 kV transmission line is complete and bush clearing is 70% completed.

Le Plaque discovery to add to Ity mine complex

The 100%-owned Le Plaque target, the discovery of which was announced on 29 May 2017, has the potential to be the next significant discovery following the recent Daapleu and Bakatouo discoveries, respectively 1.3 Moz and 0.7 Moz of indicated resources.

The Le Plaque area covers 4 km2, located within 5 km of the Ity mine complex and the future CIL plant location. Several high-grade mineralised trends stretching over 400 m were identified, with the largest being a 2 km long geochemical anomaly with best values >1 000 ppb. The trends are all open along strike and at depth.

To date, approximately 25% of the Le Plaque target was drilled, in an area named Le Plaque Main, for which a maiden Indicated resource of 85koz at 2.70 g/t and an Inferred resource of 43Koz at 2.40 g/t was delineated.

This maiden resource positions Le Plaque Main to be amongst Ity’s highest grade deposits; 75% of the holes drilled in this area encountered intersects thicker than 2 m with grades higher than 2g/t.

A high resolution ground IP/resistivity survey is currently underway on the Le Plaque area which will be followed by a new drilling campaign in the coming months, with the goal of delineating the extensions and investigating other high-grade targets in proximity.

2018 drilling will also be guided with the integration of high helicopter borne combination Mag/Radiometric/VTEM geophysical surveys flown in 2017 by Geotech. Data collected to date suggests that extensions of the Le Plaque Main deposit are constrained by the lack of drill information.

In addition to the Le Plaque area, several other near-mill targets have been identified, which represents a small portion of the 100 km corridor controlled by Endeavour Mining.

2018 exploration programme

A $7 million exploration program is planned for 2018 at Ity to further explore the Le Plaque target in addition to several other near-mill targets (including testing of extensions at the Mont Ity, Bakatouo and Daapleu deposits), and on greenfield targets located within the 100 km corridor along the Ity mine.

The following targets will be tested:

  • Le Plaque area and nearby targets: Drilling to be guided by the integration of the full airborne and ground geophysics survey
  • Ity deposit: Drilling to focus on the lateral hanging wall new mineralization discovered in 2017 in the northern part
  • Daapleu deposit: Drilling to test deep and possible lateral ore shoots
  • Bakatouo deposit: Drilling to test extension of the deposit to the East and to the West of the Cavally river
  • Other near-mine: Air core reconnaissance of a large and untested area East of Bakatouo
  • Greenfield targets: Several targets being tested within the 100km corridor along the Ity mine
