After more than 1 year's investigation, geologists from Shandong Provincial Bureau of Geology & Mineral Resources discovered a new super-large iron ore in Jining. The amount of iron reserve is over 1 billion tons in Yandian ore section in Gunzhou. At the same time, the discovery of super-large iron ore solved the problem of aeromagnetic anomaly in the north of China for 50 years.
It is said the aeromagnetic anomaly in Jining was found in 1958, and then several geological surveys on the district have no breakthrough in the nearly 40 years. In September 2007, the geologists from Shandong Provincial Bureau of Geology & Mineral Resources took 10 drilling rigs to drill in Yandian ore section around the area of 19.04 Km2. According to the gravity anomaly, aeromagnetic anomaly, and the drill, it can ascertain that the super-large iron ore is located in the depth of 1020-2200 m, and is mainly quartz-magnet, thickness of 80.46-190 m, grade of 25.97% -31.72%, and reserve of 1 billion tons.
