Conceptual, Pre-feasibility and Feasibility Study


 
The Pre-feasibility Study and Feasibility Study of Mining project in Mongolia must be prepared by an authorized organization holding the appropriate permits or by mining consulting engineer . If the Feasibility Study is prepared by a foreign organization it also must be translated by an authorized organization holding the appropriate permits or by mining consulting engineer.
According to the regulations, assessing the feasibility of a mining project has three different stages : 


·         Preliminary evaluation of project – Conceptual Study. This prepares a basic evaluation of the economic feasibility of the mining project development based on mineral reserves discovered during the exploration. 
·         Technical economic evaluation – Prefeasibility Study. This document analyzes the economic evaluation of various scenarios prepared for the state resources registration of mineral deposits measured during the exploration. The ecological impact should be assessed according to the mining methodology.  
·         Technical and economic feasibility – Feasibility Study. This document contains a detailed analysis of deposit geology, engineering decisions, legal, operational, economic, social, environmental and other factors prepared to support mining project finance.

Minerals Law proposed a pre-mining operation period to allow for the preparation of the design package, feasibility study, mine development and commencement of production. Pre-mining operation is the period after exploration is completed and the mineral deposit reserve is registered with State resources and shall be no more than 3 years after expiration of the exploration license. Exploration license holders may apply to MRAM for a pre-mining agreement.

Minerals Law states that the Feasibility Study on the development of the deposit shall be submitted within 60 days of obtaining a mining license. MRAM Director Order No 415 from 2009 sets the requirements and procedure to approve feasibility studies, which must include the following:
