There's a new plan to unlock a magnetite mining hub in WA
Hematite is a higher grade in the ground, while magnetite deposits are large and quite low grade – but produce super high-grade products.) Most recently, plans for a ~$10 billion rail system and deep water port called 'Oakajee' near Geraldton proved unviable as soon as iron ore prices retreated from their 2011 peaks.
