The Yubileyno-Snegirikhinskoe, (also known as Yubileyno-Snegirikhinsky) deposit is a small polymetallic VHMS deposit within the Rudny Altay Volcanic Arc, in the Leninogorsk/Ridder district of eastern Kazakhstan. It is located 35 km NNW Ridder (#Location: 50° 38' 31"N, 83° 37' 12"E).
For details of the regional setting, see the Regional Setting section of the 50 Let Oktyabrya record.
The deposit was brought into production in 1964, and in 2009 treated 0.60 Mt of ore averaging 3.26% Cu and 2.45% Zn.
Ore is present in a number of orebodies occurring as a series of sub-parallel pods that are elongated in a steep to sub-vertical direction and are gently folded. Individual orebodies vary from 2 to 30 m in thickness, averaging 18 m. The Western orebody, which comprises around a third of the resources, is ~150 m wide, and persists for 600 m down-dip. The Central orebody is ~20 m wide and also extends for ~600 m down-plunge, while the deeper Central No. 2 orebody is 150 to 200 m wide and ~500 m down-plunge. The No. 7 lens, which is located to the east of the Central orebodies is ~100 m wide and extends for 600 m down-dip.
Mineral resources remaining as at 1 January, 2011 were (IMC Group Consulting Ltd, 2011. Competent Persons Report to Kazakhmys Plc):
Measured resource - 1.177 Mt @ 3.41% Cu, 5.22% Zn, 0.61 g/t Au, 41.05 g/t Ag, 0.89% Pb;
Indicated resource - 0.318 Mt @ 3.59% Cu, 1.72% Zn, 0.29 g/t Au, 17.94 g/t Ag, 0.23% Pb;
TOTAL resource - 1.494 Mt @ 3.45% Cu, 4.47% Zn, 0.54 g/t Au, 36.14 g/t Ag, 0.75% Pb;
Ore reserves (same date and source - included in resource)
TOTAL reserve - 1.718 Mt @ 2.76% Cu, 3.58% Zn, 0.43 g/t Au, 28.91 g/t Ag, 0.60% Pb.
