   Abstract:
   Cu and polymetal Anarak deposits are located at the northern side of the Esfahan Province. These deposits have a long history of exploitation. Old workings and smelting slag are distributed across Central Iran Great Desert from Dom Mountain (Qermez Cu-Au mine) to Doshakh Mountain (Chahpalang Au-W-Cu mine). Also there are remnants of traditional furnaces in the abandoned mines of the area showing the age of mines. What preserved so far, going back to the last period of exploitation by German experts at 1945, end of Second World War.
   The ore of these mines was processed to several forms. Part of ore was transported to Tehran and the other part was transported to near mines such as Sabrz and Baqoroq that have smelting facilities. The final product of these mines has been exported.
   Later, the Anarak Metal Company and other operating miners carried out more exploration in the area, but no one of these works lead to exploitation.
   At 1975, geological, geochemical and geophysical investigations were conducted in the area by Russian Mineral Export Company, under a contract with Geological Survey of Iran. These results of these investigations were published in 14 reports.
   The Baqoroq deposit is a hydrothermal mineralization within carbonate and clastic rocks of Cretaceous. Barite and calcite veins in the mine contain disseminated ore mineralization. There are E-W and NW striking faults in the area which control the mineralization. Ore-bearing zones are 50-60 m deep, several tens of meter long and no more than several meters thick. The areas of previously exploited zones are 80*120 and 80*60 m. At whole of mineralized area, mineralization has occurred as pocket, stockwork, fractured-zone filling and lumpy forms. Samples contained 2-11% Cu and 2-400 ppm Pb. Available mining wastes that have considerable quantity, contain up to 2.4% Cu and 9 ppm Ag.
   According to the geochemical interpretation of Cu-zonality coefficient gained from point-sampling, copper mineralization exists at depth. This correlates with copper minerals at eastern portion of the deposit.
   Geophysical exploration revealed 18 anomalies, of which seven ones are suggested for further exploration. In addition, possibly, hidden copper reserves exist far from former operated site, under Quaternary deposits.
