The Yolagh Iron- Oxide-Apatite (IOA) district with 99.6 km2 areas is located in the Markazi province and 17 km northwest of the Saveh city. It is part of the Urmia-dokhtar where a number of magmatism belt, Access road to the area is through the Tehran-Hamedan freeway, after 2 km of the Nuraly Beyg subway to Yolagh can be entered from the southeast part of target area.
