Dimensions of mineralization

In the mineral area, the 3 types of mineralization with different genesis is important, including: Banded Iron Formation mineralization in the western part of the area, hosted by volcanic rocks with an average thickness of iron and jasper layers between 5 to 10 meters and a mineralization length of about 250 meters. Skarn iron in the eastern part of the area is hosted by granite intrusion (quartz monzodiorite) in the form of numerous magnetite-apatite veins with a thickness of 1 to 2 meters and a length of about 200 meters, and finally, copper mineralization in siliceous patches in the lower waist The intrusion mass of the east of the range is about 0.5 meters to 1 meter thick and about 20 meters long.

Proven reserve

The total reserve in Niaz iron, considering 20% as the economic limit grade, is equal to 600681 tons of iron ore with an average grade of 29/4%.
It should be noted that at present, this reserve estimate has been done only on the BIF zone and exploration operations in this area are still being carried out on the Iron skarn and Copper zone. This amount of reserves is expected to increase significantly.

Mineral grade

Fe total maximum 62/2% and average 36%, Cu maximum 2/2% and average 0/45%, Au maximum 4957 ppb and average 500 ppb, Ce maximum more than 1% and Mo maximum 1218 ppm and an average of 128 ppm.

Facilities

The area is located in 2.5 km of Nivesht village, which can provide the required manpower and electricity.
Also, Saveh-Hamedan freeway is located 7 km from Nivesht village.
