Deposit Type

  • Banded iron formation


Summary:

The Jack Hills Resource comprises banded iron formation (BIF-BFO) of 2,870 Mt at 30.7 % Fe, Massive Iron Mineralisation (MIM), Direct Shipping material (MIM-DSO) of 133 Mt at 56.2 % Fe, Massive Iron Mineralisation potential Jig Feed or BFO (MIM-JIG) of 96 Mt at 45.5 % Fe and Detrital Iron Deposits (DID) which includes potential BFO, Jig feed canga or colluvium deposits of 118 Mt at 32.6 % Fe.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Conventional large-scale truck and shovel mining method.

The JHEP mine plan, which has a projected life of 39 years, envisages a high-volume strip mining method utilising large-scale mining fleet at multiple working faces to produce a consistent quality of ore feed for the processing plant, with an average life of mine strip ratio of approximately 0.94:1.

Processing

  • Gravity separation
  • Flotation
  • Magnetic separation

Summary:

The plant design incorporates established equipment and processing technologies used domestically and internationally within the iron ore and other extractive industries.

Each concentrator module will utilise conventional low-intensity magnetic separation to produce a premium magnetite pellet feed concentrate and a gravity / flotation circuit to produce a high quality hematite sinter feed concentrate. Pilot testing of the flowsheet achieved total iron recovery of 74.8%.
