Reserve Amount

Dimensions of the mineral in the vein section, which consists of about 40 mineralization veins and silica-carbonate veins, has a length of several tens of meters to several hundred with width from 1 meter to more than 30 meters and a height of between 1 and 15 meters. Also in the porphyry section, stockworks, veins and veinlets are found in several regions with different dimensions in which molybdenum, gold and copper anomalies have been identified. In the eastern mass, the dimensions of mineralization are approximately 200 × ۱۰۰ m, with a height of ​​about 40 meters and in the western mass is 200 × ۵۰۰ meters and a height of about 15 meters.

In this district, copper grade is between 1.0% to 1.7%, molybdenum grade is between 10 to 212 ppm, gold grade range is from 50 to 8200 ppb, silver grade range is from 10 to 182 ppm, lead grade from 0.1 to 6.2% Zinc grade is from 1.0 to 5.0 percent, arsenic is from 200 to 5000 ppm, and the antimony grade is from 100 to 3100 ppm.

Proven Reserve

Proven reserve of copper with cutoff grade of 0.2% and the average grade of 0. 5% copper have been estimated 266.300 tones and the probable reserve have been considered 528,000 tones. Also, proven reserve for the gold element as a copper byproduct, with the grade of 0.2 (ppm) and the average grade of 0.52 (ppm) is 105,340 tons of ore, equivalent to 53 kilograms of gold.
