In the Muteh mineral zone, except the old exploitations that named Shaddadi works, there are exploration and exploitation operations done by the Ministry of Mines and Metals "currently the Ministry of Industries and Mines" between 1955 to 1986 under the "Program of exploration and equipping of Muteh Gold mine".
These operations were mostly executed on the known mines and indications that prepared as maps, reports and documents separately for each mine. The mines include:
1- Chah Khatun
3- Qorm Qorm
4- Darreh Ashki
5- Cheshmeh Gohar
8- Tangeh Zar
9- Chah Allameh
The reserve estimation and designation of Chah-Khatun and Senjedeh mines were done by BHP Company on the base which the processing and smelting plants were constructed. Then the complex was transferred to the Iran Gold Company.
In order to identify the available situation and plan for exploration and development of reserves, the Iran Gold Company assigned the evaluation of existing exploration data of remained mines to this consulting engineers company.
For this, a large amount of data including maps, reports, sample analyses and else were obtained from the employer. At fist, all data were categorized and related appropriate data were computerized. Previously estimated reserves were reevaluated simultaneously. Considering the performed evaluations and uncertainties in the reports, all related data were reprocessed.
The result shows that previously estimated grade (4 ppm) for Qorm Qorm, Darreh Ashki, Cheshmeh Gohar, Chah Bagh and Tangeh Zar is not factual. Also the estimated tonnage is not in accordance to the same class of deposits. To make the estimations more accurate, it is require doing some low-cost explorational activities.
Considering the previous works, it is concluded that the whole of the area, or the region between above mentioned mines and surrounding zone was not identified in detail and required further work.
