Centrex Metals Limited is an Australian based resources exploration and mining company. It has interests in Western Australia and South Australia. The company's chairman is notable South Australian engineer and businessman, David Klingberg.
The company is primarily focussed on the development of the Oxley potassium fertiliser mine and processing complex in Western Australia, southeast of the Port of Geraldton. The project comprises a rare large-scale long outcropping potassium feldspar rich lava flow. Centrex has developed a process to convert potassium feldspar into potassium fertiliser products. It also has the Ardmore phosphate rock project 128 km south of Mount Isa in northwestern Queensland.
Centrex also has active exploration for base metals at Goulburn in the Lachlan Fold Belt of New South Wales. It also has exploration for gold in the Lachlan Fold Belt at Woolgarlo, 10 km west of Yass.
Iron ore.
Centrex owned several iron ore deposits on Eyre Peninsula in South Australia. including at Wilgerup, southeast of Lock; Kimba Gap, west of Whyalla, adjacent to existing Middleback Range mines; and the Fusion Magnetite Project near Koppio.
Wilgerup had an approved mining lease from the South Australian government, but did not start active mining, and no longer appears on the map of active projects on the Centrex web site. The leases have been surrendered or expired.
Eyre Iron Pty Ltd was the management company for the Eyre Peninsula Joint Venture between partners Centrex Metals Ltd and Wugang Australian Resources Investment Pty Ltd, a 100% owned subsidiary of Wuhan Iron and Steel Corporation, China’s third largest steel producer.
Eyre Iron Pty Ltd proposed in 2011 to develop an open pit magnetite mine located in the Koppio Hills on southern Eyre Peninsula, known as the Fusion Magnetite Project. It included a processing plant site adjacent to the mine site and an underground magnetite slurry and water pipeline corridor from the processing plant to a proposed deepwater export port initially named Sheep Hill, and later Port Spencer.
The port would also be served by a railway branch to carry ore from the proposed Wilgerup mine. The Government of South Australia declared the port facility a major development. The joint venture was wound up in 2016; land purchased for the project was publicly advertised for sale in 2017.
