OPERATIONS
Mnogovershinnoye (MNV) - Khabarovsk Region, Russia
Processing plant throughput for the first six months of 2015 was 705,493 tonnes of ore, yielding 42,451 oz of gold. Recovery rates averaged 89%, a slight decrease from the same period in 2014. The dip was due to changes in the mineral composition of the ore and a decline in gold grades.
Open-pit and underground ore production totalled 619,749 tonnes. Underground development recorded a 7% increase to 4,287 metres from the previous six months.
The average ore grade was 2.15 g/t, which is 37% less than the same period of 2014. The reduction is due to the commencement of mining at the Verkhneye, Tikhoye, and Valunistoye ore bodies, which have slightly lower gold grades.

** The Company has re-estimated the Novo deposit's ore reserves based on the results of mining and grade control drilling as of January 01, 2014. The recalculation has received approval from Russian regulatory authorities, however, updated JORC Ore Reserves have not yet been determined. Total Russian-classification reserves increased by 77% from 9.42 million tonnes of ore to 16.69 million tonnes. The figure includes lower reserves of Pb (down 4% from 348.7 kt to 334.8 kt) and Zn (down 4% from 169.9 kt to 159.1 kt), but increased reserves of Au (up 24% from 30.8 kt to 38.4 kt) and Ag (up 18% from 811.1 kt to 959.7 kt).
Belaya Gora - Khabarovsk Region, Russia
First-half ore production at Belaya Gora reached 885,314 tonnes, an increase of 91% from the same period of 2014 and in line with project forecasts. The average ore grade was 1.63 g/t, a 4% increase over the same period last year.
The Belaya Gora plant saw the full commissioning of its first processing stage in H1, with nameplate production parameters achieved at most of the plant's equipment. Ore processing reached 674,985 tonnes, which is 46% higher than in the same period last year. The average recovery rate was 76%, which is 21% higher than in H1 2014 and also in line with project parameters. The recovery rate reached 80.9% in June of this year.
The process of commissioning the plant's second stage continues, with all equipment in place and optimisation of the process flow underway. Design documentation and a tender process have been completed for the installation of automated process control systems. Additional Knelson separators were also delivered to site.
RC grade control drilling was introduced for the first time at Belaya Gora during the first half of the year. This will allow the Company to reduce dilution as well as to clarify ore contours, thus providing improved production forecasting accuracy going forward.
The government's Main Ecological Expert Review Panel issued a positive ruling on design documentation for the construction of a solid waste landfill in the vicinity of the nearby village of Chlya. Project materials are currently undergoing the Main State Expert Review, and a construction contractor is being selected.
