Deposit type

  • Bedded Iron (BID)
  • Detrital Iron (DID)

Summary:

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. Mineralisation within the Flying Fish deposit is a hosted Detrital Iron Deposit (DID) and Bedded Iron Deposit (BID). Outcropping geology in the project is Marra Mamba Hills. Bedded mineralisation is found within the Mount Newman and MacLeod units of the Marra Mamba Iron Formation. 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. At Flying Fish mineralisation is predominantly bedded iron deposits (BID) with some detrital iron deposits (DID). Channel iron deposits (CID) occur in the area but are not considered economic. Mineralisation is hosted by the Mount Newman and MacLeod Members of the Marra Mamba Iron Formation, there is minor mineralisation in the West Angela Member of the Wittenoom Formation. The majority of the detrital mineralisation is found as Red Ochre Detritals (ROD). 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. 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. Mineralisation in the Mount Macleod is occurring across the Flying Fish deposit with the largest mineralised footprint found in the south-west of the project area. This area covers 1km in length and 200 metres across strike. The ROD mineralisation occurs in a series of pods ranging in size from 100m to 300m except for the central part of the ore body which extends over 2km trending in a north-east direction averaging 200m across strike. Mineralised thicknesses in this unit are between 20m to 190m.
