The Middleback Ranges have been the site of continuous iron ore mining for more than 100 years, playing a key role in the development of the nearby region. This has continued in recent years, with the operations pivotal in the creation of Arrium Mining.
A defining moment in Arrium’s history occurred in 2005 when the Board decided to enter the export iron ore market through Project Magnet. This was achieved through converting our Whyalla Steelworks to magnetite iron ore feed from the Middleback Ranges, thereby freeing up the more marketable and valuable hematite ore from the Middleback Ranges for external sale. Project Magnet was originally premised on delivering 4mtpa at completion. This was achieved in 2007 on time, and was subsequently increased to 5mtpa in 2009 and to 6mtpa in 2010, through ‘sweating’ our supply chain. The business is expected to be able to maintain export iron ore sales of approximately 6mtpa from the Middleback Ranges for at least 10 years based on its reserves and resources, and the beneficiation of low grade ore.
At completion of Project Magnet in 2007, the mining operation included four active pits (Iron Duke, Iron Magnet, Iron Duchess and Iron Knight) in two mining areas over a 10km region. Today in the Middleback, we operate in three mining regions with multiple pits (Iron Duchess, Iron Knight, Iron Duke, Iron Magnet, Iron Baron and Iron Chieftain).
