The Eliwana deposit occurs on the southern limb of the Jeerinah anticline in the western Hamersley Province. The deposit covers a narrow zone that follows the outcrop of mineralised Brockman and Marra Mamba Iron Formations, with Tertiary sediments in the valleys separating these formations. Iron mineralisation predominantly occurs as bedded iron deposits (BID) with some detrital iron deposits (DID). The mineralisation, which occurs at surface and extends to depths of 350m below surface, is variably distributed across an area of approximately 40km along strike and 3.5km across strike.

The Marra Mamba Iron Formation outcrops in the north and dips towards the south around 15 to 20 degrees. Tertiary sediments occur in the valley. Minor occurrences of the Oakover Formation are mapped outcropping in the western portion of the project area. The main area of mineralisation occurs over an area 11km along strike and 400m across strike. Mount Newman Mineralisation occurs at surface in the north and at depths up to 200m to the south. The thickness of mineralisation averages 20m throughout the deposit and is found up to 50m in areas.

At Eliwana mineralisation is distributed variably within an area of approximately 40km in an east west direction and 3.5km in a north south direction. Mineralisation occurs at surface and extends to depths of up to 350 metres below the ground surface. The reported tonnes and grade in the Mineral Resource occur at depths of up to 350 metres.

It is assumed that mining will be carried out with medium to large scale mining equipment, bench heights may vary depending on mining studies. These methods will be similar to analogous Fortescue deposits where conventional: truck & shovel/excavator; drill & blast and; grade control methods are used. The impact of dilution will be assessed as part of the mining studies.

Components of the OPF (screens, crushers (jaw/cone/mills), conveyors:
- ROM Bin (BN101);
- Apron feeder (AF101);
- Primary crusher (Gyratory crusher, CRG101):
- Feed = -1,500mm;
- Product = -250mm;
- Hybrid feeders (Low profile feeders, BF221 & BF211);
- Scalping screens (SN211 & SN221);
- Secondary crushers (Sizer crushers, SZ211 & SZ221);
- Feed = -250mm;
- Product = -150mm;
- Belt feeders (BF311, BF321, & BF331);
- Tertiary Crushers (Cone crushers, CRC311, CRC 321, & CRC331):
- Feed = -150mm;
- Product = -31.5mm;
- Product screens (SN311, SN321, & SN331);
- Vibrating pan feeders (VF311, VF321, VF322, & VF331);
- Plant Conveyors (CV211, CV221, CV212, CV222, CV311, CV321, CV331, CV701 & CV702).

The output of the OPF will be 30MT of iron ore product per annum. The overland conveyor, stockpile and TLO, allow management of the iron ore product and loading of trains to allow the transport of the product to Fortescues Herb Elliot Port Facility in Port Headland, via Fortescue’s train network.

The OPF is a dry processing plant which takes product from the feed size down to the product size via a three stage crushing and screening process. The OPF does not remove any impurities/waste and does not produced tailings.

The product is then transferred to the overland Conveyor (CV703) and taken either straight to the TLO or stacked on stockpile (ST80-1) via the Stock piling conveyor (CV803) where it can be reclaimed for loading through the Stacker/Reclaimer when required. Components of the overland conveyor and TLO:
- Overland Conveyor (CV703);
- Sampling Stations (SS701 & SS901);
- Stockpiling conveyor (CV801 & CV803);
- Stacker/Reclaimer;
