  In each country, optimal utilization of available & unused capital is one of the basics for sustainable development. In this direction, revision of abandoned mines in Iran is of special importance & it is necessary to reevaluate the mines & unused capital for proper utilization & increasing profit

   The highest risk of exploration operations and exploration investment is usually at the prospecting stage in depth. At this stage, with regard to the results of evidences, which come from the surface and their promising conclusions, decisions are made in order to examine the depth and further exploration. This phase is one of the other properties of the abandoned mines. Thus, if these mines are introduced properly, they will have lower risks and more attraction for the investors.
    3. Abandoning process of mine:
   In foreign countries, each index passes different stages to reach a definite reserve.
   From passing a stage to another, a process may be occurred to make a mine abandoned. The mentioned stages are as follows;
   For each stage of exploration operations, which results to gain data from a mineral producing region, a definition is available. The last definition, which explains different stages, is Jorcdiagram.
   In the above-mentioned diagrams, with regard to the exploration operation, minerals are divided to two main groups;
   Mineral resources group: This word is used for discovered reserves and materials that the exploitation of them is uneconomic at this stage and mineral masses were not discovered there.
   Mineral reserves group: This word is used for mineral masses that the existence of them is proved by excavation or other exploration methods or mineral masses that the availability of them is guessed in a particular region via high percentage are called mineral reserves.
