It’s reported that this iron was found during the second exploration of the city, which is based on the city's fifteen years of geological data. After it was reported to the China Geological Survey, it was perambulated by a team of geologists.
The team made 17 exploratory holes to explore the mine. Iron ore was found in 12 of the holes, covering an area of four kilometers long, three kilometers wide.
According to antecedent survey, a complete core of iron ore has been detected 1,100 to 1860 meters. High-grade resources can even be found underground 2015 meters. The bottom and border zones haven’t been reached, said the team. The identified reserves available are more than three billion tons.
Meanwhile, the Dataigou mine has features of deep-buried depth, wide-spread ore body, steep obliquity and big scale of ore body. The iron deposit is a giant mixture of magnetite and hematite, with iron ore grade between 25% to 62%.
Shaoshi Xu, head of Minister of Land and Resources, paid a site visit there, urging the local government to do their best to make full use of Asia's largest iron ore mine for the nation and local as soon as possible.
