Özet (Çeviri)

The Kirazlı project is an epithermal, highly sulphidised and disseminated gold deposit located in the northern sector of the Aegean Horst and Graben System. The heterolithic phreatomagma / phreatic brecy is dominated by the gold mineralisation, which passes through andesist tuffs of the Oligo-Miocene period. Mineralization can usually be subdivided into two main types: firstly, the low-grade regional gold zone that is primarily based on Kirazlı and that includes vast areas of high grade gold. This low level mineralisation takes place both above the supergenic oxidation region and redox boundary. Furthermore, four elongated bodies of gold mineralisation, which occur in the highest argillic / advanced argillic region and slightly overlap the base of the silica cap. The Kirazlı project is a low-cost, 100% funded development project with a high return on investment. For A˘gı Da˘gı and Kirazlı projects successful feasibility studies completed in 2017, the two projects envisaged as open-pit, heap-leach operations separately. Alamos Gold expects first to develop Kirazlı then use its cash flows to fund A˘gı Da˘gı project's growth. Kirazlı is expected to generate, on average, 104,000 oz of gold over a five-year mine life, as outlined in the feasibility study. The key objectives of this study are to analyze the Kirazlı project from technological and financial perspectives, with an emphasis on currencies, recovery rates, and change in production rate. A discounted cash flow (DCF) analysis and Monte Carlo Simulations for the base and extended case to produce a net present value (NPV) and internal rate of return (IRR) distributions, and Real Option Valuation (ROV) were carried out. The DCF for Kirazlı project produced an NPV of US$ 364 million at the base case, and an NPV of US$ 249 million at the extended case with an IRR of 91% and 87%, respectively by using current gold prices and country's cost index.
