2018 Outlook

Leach Pad

The Company ceased stacking ore on the leach pad in April 2018. Production since then has been from the remaining inventory on the pad.

Updated 2018 production at Kışladağ and expected production from the leach pad for 2019 and 2020, was reported on October 25, 2018. Revised 2018 production is forecast to be 160,000 – 170,000 ounces of gold from the leach pad at a cash cost of $650-$700 per ounce including roughly $300 per ounce of non-cash costs.

Mill Project

In October 2018, following the completion of the feasibility study, the Board of Directors approved the advancement of the mill project at Kışladağ. The feasibility study indicates that the construction of a conventional carbon in pulp mill at Kışladağ is economically robust. The mill supports a 3.1 million ounce reserve with expected metallurgical recoveries of approximately 80%, to produce an average of 270,000 ounces of gold per year over nine years.

The project is expected to begin commissioning activities in late 2020, with production expected in the first half of 2021.

Geology and Mineralization

Kışladağ 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 Kışladağ 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.

Exploration

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