GEOLOGICAL AND ECONOMIC EVALUATION OF MINERAL OCCURRENCES AND DEPOSITS, RESERVES ESTIMATION
TsNIGRI designs:- Aggregate geological and economic modeling techniques.
- Inferred resources and reserves estimation techniques.
They are used at DPBM deposits.
Geological and economic modeling of investment projects- Tonnage and quality of economic minerals, mining and processing parameters and indicators.
- Production rates, timelines and cost of deposit additional study and development.
- Potential market value of a deposit.
- Investment attractiveness.
- Subeconomic values of the highest-risk development indicators.
- Budget efficiency and social significance.
- Estimated mineral use terms and initial payment amount.

The technique was tested at over 70 DPBM deposits.
TsNIGRI feasibility work types:
- feasibility considerations;
- feasibility recommendations;
- feasibility studies.
DPBM deposit development feasibility studies involving conditions feasibility studies and reserves estimation are performed for subsurface users, specifically:
- Exploration data analysis and interpretation.
- Database compilation.
- Geological modeling involving multivariant reserves estimation.
- Mine planning.
- Selection of the best mineral processing flowsheet.
- Multivariant calculation of deposit development performance.
- Recommendations for future efficient deposit development.
