Iron ore prospect, and medium term mine potential. Owned by Rio Tinto. In 2011, in addition, Iron Ore Holdings sold their Koodaideri South leases to Rio for 32 Million (Australia), plus 2% of any royalties from mining.
The leases are located 20 kilometres north of Rio's Yandicoogina mine, just south of the Munjini-Roy Hill Road, and west of the railway line to the Yandi mine. It is 110 kilometres north-west of Newman.
Ore deposits runs west north-west to east south-east. Named as 75W furthest west, then 58W, and 38W/21W. The last was initially explored by Mount Bruce Mining Limited in the 1970's.
The deposits are bedded iron hosted in the Dales Gorge Member of the Archaean Brockman Iron Formation. Mineralisation occurs as a high phosphorous Brockman iron deposit with upper weathering. Mineralisation extends on strike for 4.5 kilometres for both 75W and 58W, and 8.6 kilometres for 38W/21W. The width of 75W and 58W is 2.5 kilometres, and for 38W/21W 2.8 kilometres. Deposits reach a maximum depth of 100 metres below the surface, averaging at 75 metres. Over the deposits is a hardcap varying from 2 to 40 metres thick, averaging 20 metres.
A mine at the location is estimated as capable of 70 mtpa for 30 years. It would need also a 167 kilometre railway to be built to Rio's Tom Price to Dampier existing line. The estimated cost to build the mine is 3.5 billion (Australian).
