2018 Outlook

In response to the lower expected gold recoveries reported on 23 October 2017, work is progressing on assessing multiple processing solutions with a focus on a milling option. The Company expects to file a Prefeasibility Report by the end of the first quarter of 2018 and will make a decision on a potential processing option based on this report.

Until the report is complete, operating guidance for Kisladag is for Q1 2018 only. In the first quarter, Kisladag is expected to place 3.1 million tonnes of ore on the leach pad at a grade of 1.25 grams per tonne gold, producing 40,000-50,000 ounces of gold at cash operating costs of $550-650 per ounce. Sustaining capital expenditure for the first quarter is expected to be $11 million.

Geology and Mineralization

Kişladağ is a porphyry gold deposit that formed beneath a coeval Miocene volcanic complex in Western Anatolia, Turkey. At least four latite intrusive phases are recognized in the deposit. Alteration consists of a potassic core with K-feldspar, biotite, quartz and locally magnetite, outwardly overprinted by illite, kaolinite, quartz, and tourmaline. Remnants of a quartz-alunite lithocap are found near surface. Gold mineralization occurs within zones of quartz-pyrite stockwork and disseminations. Oxidation extends to a depth of 20 to 80 metres but there is no supergene enrichment. The mineralized intrusions at Kişladağ are enclosed within volcanic and volcaniclastic strata that overlie basement schist and gneiss of the Menderes Massif Core Complex. These strata dip outward from the deposit core, and display rapid facies changes from massive lavas and coarse poorly stratified units proximal to the porphyry centre, to finer well-stratified volcaniclastic strata that interfinger with lacustrine sedimentary rocks in surrounding sedimentary basins.


The Kişladağ deposit was an original discovery made by Eldorado in the late 1990's during a regional grassroots exploration program. Our current exploration in the Kişladağ district is focused on defining and testing potential nearby satellite deposits, and identifying other porphyry centers in the surrounding region.
