Khansorkh Copper IOCG

Projects

The copper district of Khansorkh with the surface area of 9.47 km2 is located in Kerman province near Sirjan city. This district is located in the Urumieh-Dokhtar (Tanguyeh) exploration zone. The target district is in 60 km of asphalted road (Bardsir-Sirjan) toward Sirjan (Khansorkh’s checkpoint) and a dirt road with the length of 17.2 km toward Imam Zadeh Hamzeh.

Reserve type

  • Genesis: IOCG, scattered veins and mass
  • Paragenesis: Malachite, Azurite, Chalcopyrite, Chalcocite, Native Copper, Oligiste, Pyrite
  • Type of minerals and main minerals: Chalcopyrite, Chalcocite and Malachite
  • Gangue type: Silica
  • Geochemical Paragenesis: Copper, Molybdenum, Gold, Silver and Iron

Geology

  • Host rock: Granite to granodiorite, granitoid type (I) and granite aplite veins
  • Age of host rock: Eocene onwards
  • Alteration: Weak argillic around the veins

Reserve Amount

Dimensions of the mineral in the southern part due to the outcrop of ore are several veins with the length of several tens of meters (totally over 500 meters) and the width of 0.5 to 3 meters and in the northern section two veins with the length of 300 and 50 meters and the width of 0.5 to 5 meters. The average grade of the northern and southern parts is about 1.26 percent.

Proven Reserve

According to the exploration, the proven reserve is 327940 tons ore with the average grade of about 1.3 percent (it should be noted that the amount of reserve basis of the issued exploration certificate is 125,000 tons ore with the average grade of 0.5 percent). The probable reserve of ore is about 506500 tons ore with the average grade of 1.26 percent.

Facilities

Electricity and asphalted road exist within 12 km of the district. Dirt road exist up to the outcrop of mineral and water is in the region.
