Deposit Type

  • Banded iron formation


Summary:

The Mt Webber deposits (Fender, Daltons, Gibson, and Ibanez) are hosted by greenschist facies, steeply dipping, isoclinally folded, quartz magnetite BIF within the Pincunah BIF member in the North Shaw greenstone belt. The greenstone belt comprises Warrawoona Group mafic and ultramafic rocks that are unconformably overlain by rocks of the upper Sulphur Springs and Soanesville Groups; these rocks are flanked by the Shaw Granitic Complex to the east and south. BIF units within the Pincunah BIF member display tight, shallowly NE-plunging fold hinges, with shear zones and faults located along fold limbs. The iron ore deposits are located in the fold-thickened hinge areas of tight synclines. Supergene goethite ± martite ores are flat lying, superimposed on the steeply dipping BIF, and extend from surface to depths of <80 m. The deposits are <900 m long and <600 m wide, narrowing rapidly away from fold hinges to <50 m wide. Supergene goethite ± martite ores (<60 wt% Fe) are massive textured, cavity-rich, and display goethite replacement of primary quartz bands. A 1-3 m thick surface horizon of nodular laterite locally blankets flatlying areas of ridges.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Mt Webber deposit is mined by conventional open pit mining practices, rock breakage by drill and blast and excavation by load and haul. The mine is operated by a mining contractor with processed ore hauled a total distance of 230 kilometres from the product pad to the port facility in Port Hedland.


Crushing and Grinding


Processing


Summary:

The Mt Webber DSO Project initially produced ore at a rate of 3 Mtpa which increased to 7 Mtpa in the 2018.
