The 2020 airborne magnetic survey suggests that the banded iron formations are strongly folded, with the most prospective area to date being the southwest limb of the fold close to a ...

Anomalous gold (up to 730 ppb) has been discovered in banded iron formation, altered mafic volcanics, and quartz veins, with copper grades up to 3.25% also obtained in altered mafic volcanics.

The project contains an 11km strike of banded iron formation and the company’s rock chip sampling over 4km of this formation returned iron ore grades up to 58.5%. Adding interest, the Fortescue ...

Banded iron formations were deposited in the Archean and Paleoproterozoic eons, roughly between 3.8 and 1.8 billion years ago. Life back then was confined to one cell organisms in the oceans.

The Earth's surface was full of sedimentary rocks that contained Banded Iron Formations, a type of chemical sediment containing over 15% iron. Rain and volcanic activity carried large amounts of ...
