The North Zone gold mineralization is hosted within iron formation
and dacite and consists of silicified, quartz veined and sericite-altered rock with up to 15% associated pyrrhotite.
The magnetite horizon that has been targeted is hosted within the Robinson Range Iron Formation
Drilling is underway, initially assessing iron formation
and shear-hosted gold settings, and later continuing onto VMS targets as they develop.
5 kilometre part of a 14 kilometre strike body at Malelane, the drilling will be conducted on the location's southern banded iron formation
Washington, Jan 16 ( ANI ): Researchers have managed for the first time to determine the isotope composition of the rare trace elements Hafnium and Neodymium in 2,700 million year-old seawater by using high purity chemical sediments from Temagami Banded Iron Formation
(Canada) as an archive.
The total Mineral Resources inventory for Royal's Braemar Iron Formation
Prospects now stands at 2,493 Million Tonnes at 21.
The supracrustal (greenstone) belts are lithologically diverse and include basalt, greywacke, pelite, and iron formation
, along with lesser andesite, dacite, rhyolite, ultramafic rocks, conglomerate, and carbonate rocks.
29m in sulphide iron formation
with 15% pyrrhotite, 1 to 3% arsenopyrite, 5% pyrite, and quartz flooding.
View to east from 19 31'44"N / 14 00'51"W showing a series of ridges with massive banded iron formation
(BIF) forming the resistant dip-slope capping.
The style and occurrence of the gold mineralization is very similar to the Homestake Mine and many geologists have, in fact, suggested that the host iron formation
in the Rochford District and in the Homestake Mine are likely the same.
The main focus of the Peak Hill Iron project is magnetite and hematite goethite deposits hosted in the Robinson Range Iron Formation
; a sequence of interbedded BIF, granular iron formation
(GIF), siltstone and shale.

in Western Australia.
