Exploration and production of Tungsten and Molibdenum Ore at Upper Kairakty Deposit in Karagandy Region

Karagandy Region

Type of Minerals

Major Elements: Tungsten (W)

Associated Elements: Molibdenum (Mo)

Infrastructure and Description of the Area

Administratively, Upper Kairakty mine is located in Shet district of Karagandy region, 35 km from the railway station Jaryk. The deposit is located in a favorable geographical and economic conditions in the vicinity of transport and energy communications. 130 km to the north of the deposit there is a major regional and industrial center – Karagandy city. From the deposit to Agadyr village, located 65 km south-west of a road are 6 km of technological road and 59 km asphalted road. From the deposit Upper Kairakty to Northern Katpar deposit the dumping paintings made by the railroad with bridges and drainages length of about 42 km. In the vicinity of the open-pit the administrative building is located (parts of administrative buildings are remained) .In Upper Kairakty village there are incomplete construction of apartment buildings (the boxes). The nearest fuel and energy base is the Karagandy coal basin (160 km). In 200 km northwest distance the Shubarkul coal deposit is being developed, which can provide all enterprises of the district. External energy supply of the future may be provided by transmission lines - 500 kV «Balkhash-Karagandy» or «Pavlodar-Central Asia» from the substation of the enterprise Agadyr. Water supply is carried out by groundwater Jaman-Sarysu and Zhaksy-Sarysu deposits with approved reserves of 130 thousand m3/day, Aktasty reservoir and the channel Irtysh-Karaganda-Zhezkazgan.

The climate of the region is a zone of dry steppes and differs sharply continental. Summers are hot and dry with little precipitation; autumn is dry, frost; Spring is short (1-2) months with a fairly high rainfall; Winter lasts about 150 days, with persistent severe winds. The average annual temperature is 2.90; in summer it rises to +37, in winter t drops to -40.

Brief Description

According to the gravity survey, the deposit is located in the zone of the granite massif on-intrusive size 17x5 km from the upper limit of 2.2 km and the lower 6-7 km. Industrial ore bodies are confined to the stockwork, formed by a series of steeply dipping quartz veins and veinlets, lying deep in the altered sedimentary rocks. General outline of the stockwork zone is 10X18 km and rare-metal productive part covers an area of 2300 m2. Tungsten mineralization is developed from the surface to a depth of 750-800 m. The molybdenum mineralization tends to lower horizons. According to geological conditions of the mine development, the deposit is related to the group of average complexity. The mineral composition of primary ore is very diverse and includes such main ore minerals such as scheelite, wolframite, molybdenite, bismuthine, pyrite, chalcopyrite, native bismuth and others. A special feature is the predominance of scheelite (over 80%).

Reserves/Resources and Brief Description of Geology

Reserves as of 01.01.2011 on categories A+B+C1 WO3 are 1 216,3 thousand tons (0.133%), Mo – 39,6 thousand tons (0.005%). The presence of rare earth elements increases the value of the main tungsten-molybdenum ore by 1,5-2 times.

Current Status and Summary of Planned Activities

In 2016, a contract was signed for the exploration and production of tungsten-molybdenum ores from the Upper Kairaktinskoye deposit in the Karaganda region. The deposit is included in the list of deposits of strategic importance.

A block model was created in the m / r of the Upper Kairakty, an expert evaluation of the block model is being completed.
Measures are being taken for sampling from the existing dumps in the Upper Kayrakty municipality and the development of a drainage project for the Upper Kairakty mine.
