Proven reserve
Designing and drilling exploratory trenches are ongoing and the proven reserve is not estimated yet. But according to geological studies, prospecting and geophysical operations, copper and iron reserve in the Silijerd exploration area is about several hundred thousand tons.
Facilities
The Villages of Vardeh and Noshveh has water, electricity, telephone and etc, which is located within 5 Km of the area and the area has good access (less than 3 km) to the asphalt road of Saveh- Hamedan border customs. There is no infrastructure or energy in the area except for the dirt road. The nearest health center is located in the Silijerd village, which is about 2 kilometers away from the exploration area.
