Industrial Development of Polymetallic Ore at Shalkiya Deposit in Kyzylorda Region with Processing Plant Construction

Type of Minerals

Major Elements: Zink (Zn), Associated Elements: Lead (Pb)

Infrastructure and Description of the Area

Shalkiya deposit is located 17 km to the northeast of Zhanakorgan town in Kyzylorda region in the south of the Republic of Kazakhstan. The nearest village that is also named Shalkiya is located 4 km south of the mine and was built in Soviet times to provide housing for the families of the miners. The current population of the village is about 5000 people. Shalkiya mine is laid with asphalt road, which is adjacent to the main road Kyzylorda – Shymkent near Zhanakorgan town. Through highway and railway, the communication routes of Zhanakorgan town is provided by transport access to the processing plant in Kentau town, as well as to the rest of the Republic of Kazakhstan, through Shymkent to Uzbekistan and China and through Kyzylorda to Russia.

The deposit has its own railway line with length of 27 km, its own power lines are 16 km, own substation with 2 transformers of 40 MW for each, the availability of water, developed underground infrastructure.

Brief Description

Shalkiya deposit was discovered in 1963. In 2001, the mine was acquired by LLP «Tau-Ken», later renamed as LLP «ShalkiyaZinc». In the period from 2002 to 2004 the maintenance works were conducted, the mining equipment was acquired. In March 2004, ore extraction at the mine has been renewed. It produced about 2 million tons of ore. In November 2008, due to a sharp drop in price for zinc and lead in the global crisis the mine production at Shalkiya was suspended in coordination with the Ministry of Energy and Natural Resources. In June 2014, JSC «Samruk-Kazyna» has acquired 100% shares of «ShalkiyaZinc Ltd». In July 2014 the shares of JSC «ShalkiyaZinc Ltd»have been transferred to the authorized capital of JSC «Tau-Ken Samruk».

Reserves/Resources and Brief Description of Geology

In 2016, Micon estimated Measured, Indicated and Inferred ore reserves of the Shalkiya (cut-off grade – 3.0% ZnEq, JORC 2012) to be 148.9 million tons, containing Pb – 1,658.0 tons (average grade – 1.11%) and Zn – 5,966.7 tons (average grade – 4.01%). Off-balance ore reserves are 119.6 million tons, containing Zn -2.71% and Pb – 0.61%.

Current Status and Summary of Planned Activities

Work is under way to expand the existing mine and build a concentrator with a capacity of 4 million tons of ore per year, a production of 100,000 tons of zinc in zinc concentrate and 20,000 tons of lead in lead concentrate. In the 1st quarter of 2020, it is planned to put into operation the first start-up complex with a capacity of 2 million tons of ore per year.
