REGIONAL NEWS - ASIA DECEMBER 2018 • E&MJ 29 FINISHING conventional drill-and-blast, truck-and- shovel methods, with a subsequent grad- ual switch to underground mining, which will last for 17 years. Total expected mine life currently stands at 27 years, which can potentially be increased by another 10 years, following additional exploration to improve confidence in the remaining mineral resources. Open-pit mining volumes are current- ly planned at 2.2 million mt/y of ore at an average stripping ratio of 9:1 waste to ore. The underground mine will util- ize long-hole stoping with partially con- solidated backfill, a method currently used to good effect by Polymetal at its Albazino mine. The Nezhda concentrator will have throughput capacity of 1.8 million mt/y. The flowsheet includes crushing, two- stage grinding, and gravity and flotation concentration. Flotation concentrates will be thickened, filtered, dried and bagged for off-site processing. Tails will be thick- ened, filtered and dry stacked in a fully lined tailings storage facility. "Nezhda is a long-life, high-grade as- set with robust economics," Polymetal CEO Vitaly Nesis said. "The project is capital light and will rely heavily on our successful experience at our Kyzyl mine in Kazakhstan. Nezhda will contribute to dividends per share beginning in 2022." Polymetal is a public company listed on the London Stock Exchange. Its pro- duction in the six months to June 30 to- taled 619,000 gold equivalent oz from mines in Russia, Kazakhstan and Arme- nia. Full-year 2018 production is forecast at 1.5 million oz. Eldorado Converting Kı ladağ From Heap Leach to Milling Following completion of a feasibility study into the viability of operating a mill- ing facility at its Kı ladağ gold mine in western Turkey, Eldorado Gold has elect- ed to proceed with construction of the project. The mine until now has produced gold via heap leaching; however, the com- pany stopped stacking ore on the leach pad in April. Production since then has been from the remaining inventory on the pad. Production for 2018 is forecast to be in the range of 160,000 ounces (oz) to 170,000 oz of gold. The new mill is planned to produce 270,000 oz/y over a project life of nine years. Processing will be based on a con- ventional carbon-in-pulp circuit. Through- put capacity is planned at 13 million met- ric ton per year (mt/y), processing feed grading 0.81 grams/mt at a recovery rate averaging 80.1%. Preproduction capital costs for the mill project are budgeted at $520 mil- lion. All-in sustaining costs of production are forecast at $793/oz. The project is expected to begin commissioning in late 2020, with first production expected in the first half of 2021. Eldorado discovered the Kı ladağ de- posit in the late 1990s during a regional grassroots exploration program. The proj- ect produced its first doré in May 2006 and reached commercial production in July of that year. Lydian Given Access to Amulsar to Winterize Equipment Lydian International Ltd. has secured short-term access to its 100% owned Amulsar Gold project to undertake win- terization and preservation work on pro- cess and mobile equipment. This work, according to the company, will reduce damage to equipment and help ensure an efficient restart of construction, mining, and commissioning activities once per- manent access has been established. "Illegal blockades have prevented Lydian from accessing the site to per- form work since late-June 2018," João Carrêlo, president and CEO of Lydian, said. "While we continue to work with all levels of government to achieve a perma- nent resolution to the current situation, we are also evaluating a range of financ- ing, strategic and legal alternatives avail- able to the company. In the meantime, it is important to be able to winterize and preserve assets at this time. This is a positive step as we work to re-establish permanent access." Since late June, illegal blockades have been in place at Amulsar that con- tinue to prevent the company and its contractors from entering the site and resuming construction work. While de- livery of certain supplies, spares, and equipment continued during the third quarter of 2018, no physical construc- tion occurred. Lydian is engaging and will continue to engage with local and national government officials to seek en- forcement of the law in order to have the illegal blockades removed.
