Dimensions of Mineralization
The area has a copper-iron mineralization zone with a length of 1000 meters and a width of about 500 meters and two zones containing copper mineralization with an area of 107 hectares are scattered.
Gold and copper mineralization is seen in the east of the area in the form of siliceous-calcite veins with a length of approximately 1 km and a thickness of 1.5 meters.
Proven reserve
The total reserve in the Kurd khalaj area, considering 0.3% as the economic limit of copper, is equal to 324667 tons of copper ore with an average grade of 0.64%, and considering 20% as the economic limit of iron, it is equal to 332952 tons. with average ore grade is 24/6%
Mineral grade
Copper average 0/64% and maximum 5%
Fe average 24/6% and maximum 44%
Gold averages 169 mg / ton and a maximum of 2364 mg / ton
It should be noted that Mo and Pb elements also have anomalies in the desired area.
