Naser Darai, born in 1959, started his career in 1978 after nine years of researching mines and five years of working in processing plants. He used his vast experience and information concerning rocks, industrial applications of minerals, their utilization, and exploration and discovery of minerals. He initiated his official operations in Chahgoshmir, Gonabad, Khorasan Province or Iran.
