Cairn Hill


Mining has temporarily ceased at the site while final expansion approvals are granted by the State and Federal Governments. Once this is complete more than $230 million in construction work will begin to upgrade infrastructure including a Wet Processing Plant, tailings dam and power station.

Once mining resumes, it is expected annual production at Cairn Hill will be three million tonnes of magnetite (3Mtpa).


Cairn Hill is located on Ingomar Station in northern South Australia, 850km north-west of Adelaide and 55km south-east of acclaimed opal mining town of Coober Pedy

The mineral lease is rich in magnetite deposits.

After an extensive $20 million upgrade, Cu-River commenced iron ore exports in June 2016 and produced and exported one million tonnes of ore in its first 12 months of operations.

The ore was hauled from the site to the Rankin Dam Rail Siding via a single lane Stuart Highway underpass, constructed to ensure the ore is transported safely and efficiently, then transported along the Darwin-Adelaide rail line to Port Adelaide for export.

Cu-River has submitted its Program for Environment Protection and Rehabilitation (PEPR) application to the South Australian Government to expand Cairn Hill and extend the life of the mine. It is hoped regulatory approvals to expand the mine will be granted in early 2019.
