Deposit Type

  • Banded iron formation hosted


Summary:

Koolyanobbing is a collective term for the ore deposits at Koolyanobbing, Mount Jackson and Windarling. There are approximately 70 miles separating the three mining areas. Banded iron formations host the mineralization, which is predominately hematite and goethite. Each deposit is characterized with different chemical and physical attributes and, in order to achieve customer product quality, ore in varying quantities from each deposit must be blended together.

The mineralization at the Koolyanobbing operations is predominantly hematite and goethite replacements in greenstone-hosted banded iron formations. Individual deposits tend to be small with complex ore-waste contact relationships. The reserves at the Koolyanobbing operations are derived from 10 separate mineral deposits distributed over a 70 mile operating radius.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Over the past five years, the Koolyanobbing operation has produced between 10.7 million and 11.8 million metric tons of iron ore products annually. During 2016, ore material was sourced from eight separate open pit mines and was delivered by typical production trucks or road trains to a crushing and screening facility located at Koolyanobbing. All of the ore from the Koolyanobbing operations is transported by rail to the Port of Esperance, 360 miles to the south, for shipment to Asian customers.

The current primary mine production fleet comprises 1x Hitachi EX2600 excavator and 4x 150t capacity dump trucks.


Crushing and Grinding


Processing


Summary:

Crushing and blending are undertaken at Koolyanobbing, where the crushing and screening plant is located.

Once the blended ore has been crushed and screened into a direct lump and fines shipping product, it is transported by rail approximately 360 miles south to the Port of Esperance, via Kalgoorlie, for shipment to our customers in Asia.
