Gold and silver recoveries by alteration type were estimated based on a column leach testing program. Testing results indicated crushing with cement agglomeration is required to achieve the estimated recoveries. The overall gold recoveries at Kirazlı are expected to average 81% while silver recoveries are lower and expected to average 31%. Reagent consumptions are low to moderate and leach times are at 90 days at both projects.
Preferred sites have been selected for heap leach facilities and waste rock dump sites at Kirazlı. Preliminary designs were completed for these facilities, and geotechnical characterization and engineering analyses were conducted to confirm stability and support the Pre-feasibility cost model.
Power connection for Kirazlı will be from an existing power line that feeds the village of Kirazlı. Approximately 4.6 kilometers of new power lines will be required to feed power to Kirazlı.
Operational water will be used at the project to wet new ore stacked on the leach pad, replace evaporation losses on the heap leach pad facilities, provide dust-control for haul roads, access roads, crushing and ADR operations, and construction activities. Water will be supplied to the projects mainly via a pipeline from the planned reservoir, from wells, and/or from surface water collected at each site.
Alamos has initiated an engineering design and feasibility study for a reservoir which will supply potable water to nearby communities in Ağı Dağı and Kirazlı, comprising over 20 villages, and sustainable process water to Ağı Dağı and Kirazlı mining operations. Alamos has committed to design and construct the reservoir in partnership with the government agency, the State Hydraulic Works (“DSI”). Dam design includes sufficient capacity for peak process water requirements and has been sized to accommodate drinking water requirements for the projected population for the year 2065 of the surrounding communities.
Since acquiring the Ağı Dağı and Kirazlı projects in early 2010 and in line with the Company’s objectives of sustainable development and social responsibility, the Company recognized the importance of improving the quality of potable water delivered to the local communities within its project areas and has committed to the development of the reservoir.
