The principal model for gold mineralization at the Kirazli Gold Property is a high-sulphidation, epithermal gold deposit. Examples of this kind of deposit in the world are Yanacocha, Pierina and Alto Chicama in Peru. Most high-sulphidation deposits are large, low-grade bulk-tonnage systems (Yanacocha), though vein-hosted high-sulphidation deposits also occur (El Indio).

At Kirazli, gold mineralization is hosted within heterolithic phreatomagmatic/phreatic breccia bodies cutting through Miocene-age andesitic tuffs. Mineralization can generally be subdivided into two main types:

- A regional low-grade gold zone that underlies much of Kirazli, broadly enveloping the high-grade gold zones. This low-grade mineralization occurs both above and below the redox horizon. The widespread, low-grade mineralization is interpreted to be early and may be associated with the broad epithermal alteration that resulted in the chalcedonic silica (the second silica event);

- Four elongate bodies of high-grade gold mineralization occur in the advanced argillic zone overlapping slightly the bottom of the 1 km-long silica cap and the silica roots. High-grade gold mineralization also shows a strong spatial relationship with the margins of heterolithic breccia bodies. These bodies transect the redox boundaries. The subhorizontal section below the silica cap is in oxide or sometimes in transition zone while the bottom of the vertical section associated with the silica r ........

The Kirazli deposit will be mined by conventional open pit hard rock mining methods. Alamos Gold plans to utilize a contract mining company to move the ore and waste from the pit. The Mineral Reserve is the total of the Proven and Probable material that is planned for processing within the mine plan. Oxide and transition ore at Kirazli will be crushed, agglomerated, conveyed and stacked on to a heap leach pad where it will be cyanide leached for the recovery of gold and silver.

During pre-production, waste will be mined to construct the heap leach facility (KHLF) foundation. Any ore incurred during pre-production will be stockpiled and re-handled to the crusher once the facilities are ready for ore processing. After a six month ramp-up period, the mine is expected to produce ore at a rate of 15,000 t/d (5.25 Mt/a) for five years. Waste produced over the mine life will be used for construction of the KHLF foundation, backfilled into the pits once mining is complete or sent to the waste rock storage facility.

Pit Phase Designs
The Kirazli pit phase designs are laid out to mine the lowest cost gold ounces with the initial phases and progress into subsequent phases containing higher cost gold ounces until the ultimate pit limits are reached. Multiple floating cones were run at “revenue factors” between 0.5 and 1.0 of the design base metal prices: $1,250/oz gold and $18.00/oz silver. Lower metal prices result in smaller cone shells of higher value and ........
