The anomly contains 643 million tonnes iron ore with an average grade of 52.70% Fe, 0.76% S and 0.11% P and is enclosed by alternation of quartzite, sericite schist, chlorite schist, talc schist, biotite schist, actinolite schist. Magnetite occurs as massive, banded, cataclastic and disseminated ore and is associated with pyrite, minor chalcopyrite and bornite. Pyrite occurs as, layered, banded, folded and cataclastic and minor within the magnetite crystals. Minor minerals are tourmaline, apatite, zircon and garnet. Geochemical data demonstrate that enrichment of Cu, Pb,Co, Sn, As and Sb in magnetite ore is 2-10 times higher than the crustal abundance. The enrichment of Cu, Mo, Pb, Zn, Cr, Ni, Co, As and Sb in sulfide minerals is 3-67 magnitudes higher than the crustal abundance. The alternation of different schist bands with banded magnetite-pyrite ores, the presence of dropstones and Al-Fe-Mn, V-Ti and V/Ti-Ni/Ti diagrams indicate that the iron mineralization in anomaly#3 is similar to the Ediacaran-type banded iron formation.
