(as amended on 18-03-2014)

1. This Instruction is developed according to Item 8 of the Regulations on State commission of the Republic of Tajikistan on inventories of minerals approved by the order of the Government of the Republic of Tajikistan of December 30, 2007 No. 656 and determines relevant requirements and instructions to content, rules of registration and procedure for representation in state examination of the materials proving permanent standards on mineral raw material for stock counting and materials of stock counting of minerals in subsoil. Besides will provide prospecting information which completeness and quality are sufficient for decision making about carrying out further prospecting works or about involvement of inventories of proved fields in industrial development, and also about designing new or reconstruction of the existing companies for production and conversion of minerals.

Chapter 1. General provisions

2. Basic concepts:

The field geological economic evaluation - determines possible economic effect of use of explored reserves in the industry. It is based on results of conducting exploration works which are generalized in case of stock counting of mineral in subsoil and includes the cumulative analysis of the factors determining cost efficiency of field operation and efficiency of capital investments in construction of industrial complex

The Feasibility Statement (FS) - the project document containing technical and economic parameters of the field development project and assessment of economic feasibility of its realization, constituted for determination of initial balance of economic interests of contract parties on mining;

Mineral raw material - the part of subsoil taken on surface (rock formation, crude ore and others) containing mineral (minerals);

Minerals - the natural mineral education containing in subsoil in strong, liquid or gaseous state (including ground waters and therapeutic muds), suitable for use in production of goods;

Subsoil - the part of earth crust located below soil stratum, or with exits of minerals to surface, and in the absence of soil stratum - below the land surface and bottom of lakes, the rivers and other reservoirs, stretching to depths available to carrying out transactions on subsurface use taking into account scientific and technical progress;

The field - the part of subsoil containing natural accumulation of mineral (minerals);

Conversion of mineral raw material - the works connected with extraction of mineral (minerals) from mineral raw material;

Passing minerals - the mineral complexes, minerals, metals and other chemical elements and their connections integrated and got with the main mineral which production and conversion in case of development of the main mineral is profitable and which economic use is economically reasonable;

Balance reserves - inventories of mineral raw material which use in case of the reached technological level is economically reasonable.

Off-balance inventories - inventories of mineral raw material which use in case of the reached technological level is economically inexpedient, but which can be further subject to industrial development.

Mining - complex of processes on extraction of minerals of subsoil.

Search works - the stage of exploration works which is carried out for the purpose of identification and okonturivaniye of perspective sites and shows of minerals, determination of forecast resources, their preliminary geological economic evaluation and reasons for further exploration works;

Standards on mineral raw material - set of quality requirements and to amount of mineral in subsoil, to mining-and-geological and other conditions of field development, the fields determining industrial value. Standards set parameters for stock counting of the main and together with them the valuable components lying in them.

3. The field geological economic evaluation, i.e. assessment of possibility of its industrial development, represents the main content of prospecting process. It is carried out at stage of search, estimative, prospecting works and in case of field operation provided that the available data on its study allow to give objective picture of quantity and quality of inventories of mineral, their industrial value, technological properties, mining, hydrogeological, ecological and other conditions of their development.

The site of the giant field, the certain field or group of the pulled together small fields based on which the construction of the mining company is possible can be object of geological economic evaluation. The site of first-priority working off can also be object of independent assessment.

4. Standards on mineral raw material represent set of economically reasonable requests to quality and amount of the minerals, mining and other conditions of their bedding providing the most complete complex and safe use of subsoil on rational geological, mining, technological and economic basis.

Standards are developed and specified in the course of geological economic evaluation of fields on materials of their investigation and operation on the basis of the special feasibility statement taking into account possibility of use of the main and together with them the lying minerals, and also the valuable components containing in them.

5. Standards according to stages of studying and development of fields are divided on prospecting and operational:

Prospecting standards ("temporary" and "permanent") are developed by results of the corresponding exploration phases and geological economic evaluation of fields for okonturivaniye and stock counting of minerals and determination of their industrial value.

Operational standards are developed in the course of working off of the field in need of refining of boundary quality requirements of the extracted mineral and to conditions of its bedding in relation to specific parts of the field: to floors, subfloors, operational blocks, panels, extraction sites, etc., differing on geological, mining, technical and economic, technological and other conditions of working off from the average values accepted in case of reasons for prospecting standards and also for ensuring stable profitable work of the company during sharp change of market conditions on mineral raw material and products of its conversion and the prices of energy resources markedly.

6. "Temporary" prospecting standards are developed by results of preliminary investigation and geological economic evaluation of fields. The feasibility statement on prospecting standards is considered with participation of subsoil users and affirm State commission of the Republic of Tajikistan on inventories of minerals in accordance with the established procedure.

7. "Permanent" prospecting standards (further - prospecting standards) it is represented subsoil users and affirm State commission of the Republic of Tajikistan on inventories of minerals on materials of complete exploration works and aim at establishment on the basis of the special feasibility statement on scales and industrial value of the field for determination of feasibility and cost efficiency of its development.

(According to categories of fields on inventory quantities) placer gold and platinum the feasibility statement on prospecting standards for each object can not be developed for fields of popular minerals and fields, small by the size. In this case subcalculating parameters for assessment of fields of popular minerals are determined according to requirements of state standard specifications, OST, specifications of the Customer or for loose gold deposits and platinum - on the basis of the integrated technical and economic calculations approved in accordance with the established procedure.

8. Temporary and permanent prospecting standards are developed for stock counting of solid minerals and hydromineral raw material taking into account the provisions "Classifications of Inventories of Fields and Forecast Resources of Minerals" and "Classifications of Operational Inventories and Forecast Resources of Ground Waters".

On the content they differ in the level of reliability of basic data on inventories and quality of mineral raw material, technological properties, mining-and-geological, hydrogeological, ecological and other conditions, and also degree of development of the proposed solutions.

9. The geological, mining, technological and economic reasons developed at the necessary level of reliability providing conditions for objective assessment of the economic importance of object and acceptance of reasoned decision concerning feasibility and efficiency of capital investments in creation of the mountain company shall comprise the feasibility statement on prospecting standards.

10. In case of reasons the Feasibility statement on prospecting standards study of the field shall provide objective assessment of all of its geological, mining, technological and other features which determine consumer properties (value) of the field. The degree of extent of exploration of the field necessary for the creation of the final version the feasibility statement on standards represented for state examination on investigation materials shall provide possibility of objective assessment of balance sheet accessory of object.

Assessment of industrial value and prospects of all inventories reconnoitered on the field is obligatory (including the category C2 inventories which are behind contour of that its part which according to the feasibility statement on standards is planned for development).

11. The material structure and technological properties of minerals, data on which are used in case of development of prospecting standards, shall be studied with detail which provides the basic data sufficient for designing of the technological scheme of their conversion with complex extraction of the components concluded in them having industrial value.

12. For fields with complex ores the possibility of use as the main, and together with them the lying minerals, and also the components containing in them shall be considered. Besides, in the calculations proving parameters of standards it is estimated and in case of positive results the possibility of use of the ground waters participating in flood of fields for hozyaystvenno - drinking water supply or extraction from them useful components is considered.

Feasibility of extraction and industrial use of the accompanying minerals of each of passing components, including ground waters, should be determined based on special technical and economic calculations.

13. Prospecting standards for stock counting of the overburden and country rocks suitable for economic use, are developed and affirm along with standards for stock counting of the main minerals. The possibility of use of overburden and country rocks and parameters of standards shall be determined in relation to the accepted technology of removal of overburden breeds and production of the main minerals. Need and feasibility of selective dredging of any parts of section of the overburden (containing) breeds concluding scarce or valuable types of raw materials (if capacity of these parts is less than vskrysha accepted in the technological scheme of removal of breeds), shall be proved by special technical and economic calculations.
