1 Field KOKTENKOL Intermediate site

2 GENERAL INFORMATION ON THE PROJECT PROJECT NAME: Koktenkol MAIN PURPOSE OF THE PROJECT: Development of technology of in situ leaching of tungsten-molybdenum ores with receiving the productive solutions containing water-soluble compounds of tungsten, molybdenum and copper. SUBSOIL USER (DECLARANT): LLC Dala Mining PERIOD OF THE PROJECT IMPLEMENTATION: PLACE OF THE PROJECT IMPLEMENTATION: From 2017 to 2058 RK, Karaganda region, Shetskiy district, Koktenkol field

3 Field KOKTENKOL The main information on the field There are two types of ores molybdenum and tungsten on the field. Molybdenum ores are developed on all three sites of the field (Southern, Intermediate and Northern). The quantity of reserves of molybdenum ores is thousand tons Tungsten ores, most concentrated on the Intermediate site are of independent industrial interest and are considered as a priority target of development. The quantity of reserves of tungsten ores is thousand tons

4 Short geological description of the Koktenkol field

5 In situ leaching (ISL) ISL advantages Development of fields by ISL method in comparison with traditional mining ways is less capital-intensive and more immediate; The prime cost at the enterprises of ISL is 2-3 times lower, than at the enterprises with traditional mining way of extraction of uranium (mine or pit). Today this method is the most profitable, also allows to fulfill ores which were considered as off-balance earlier; There are no subsidence and disturbances of the earth's surface, dumps of off-balance ores and empty rocks, and tailings (ISL-one of the most environmentally friendly methods of fields developing); СSocial and economic advantage: absence of miner's personnel, lower cost of operation; The borehole option of opening and working off of fields completely excludes any sources of dust emission.

6 In situ leaching (ISL) continuation Ore filed Mother solutions In the injection wells, the mother (leach) solution is injected Settler of mother solutions Processing of mother solutions APT The turned-out productive solution settles in a settler and is transferred to processing where useful components (including tungsten) are separated from solution Then the solution is put back into circulation, and the mixture of useful components is pre-processed to tungsten saleable products. - production well Settler of product solution Under the influence of reagents solution is sated with useful components (turns into productive solution) and extracted from the ore field through production wells - injection well

7 Research and Development (R&D) AS OF TODAY, THERE ARE FOLLOWING RESULTS OF RESEARCH AND DEVELOPMENT: 1 Experimental laboratory tests were carried out: In the statistical modes, on search of chemical reagents providing leaching of useful components from tungsten ores with method of in situ leaching; In the dynamic modes, on studying of filterability of degree and extraction of useful components in the modelled conditions. The recovery for Tungsten = 97-98%, for Molybdenum = 85-92%, for Copper = 91-92%, for Bismuth = 68-73%, from the initial content in the ore The technological scheme of receiving the productive solutions containing useful components with drawing up Production schedules is developed; The technological scheme of receiving productive solutions includes the sequence of processes of acidulation and leaching. A project of a pilot site for conducting field experiments was developed; Equipment is being assembled for experimental production.

8 STAGES OF IMPLEMENTATION OF THE PROJECT KOKTENKOL 2017: -Completion of installation and construction works; -Carrying out researches by Push Pull method; 2018: -Carrying out test production; -Development of the Project of commercial production; 2019: -Commercial production on the filed Koktenkol.
