2019 Outlook

For 2019, the Company is forecasting production of 145,000-165,000 ounces of gold, including approximately 70,000 ounces derived from ore previously placed on the leach pad. Approximately 9 million tonnes of new ore at an average grade of 1.1 grams per tonne is planned to be placed on the pad in 2019. Cash costs are estimated to be $570-620 per ounce of gold sold. Ore placed on the pad in 2019 is expected to contribute to production commencing in the second half of 2019 and into 2020.

Sustaining capital expenditures for 2019 are forecast to be approximately $10-15 million, spent primarily on capitalized waste stripping, equipment overhauls, some refurbishment work on the primary crusher and various small capital projects.

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.


The Kışladağ deposit was an original discovery made by Eldorado in the late 1990's during a regional grassroots exploration program.
