    The hematite ore is blue-grey, massive to porous and mostly micro-platy. Goethite associated with the hematite is dense, while massive, vitreous and porous cellular types are found closer to the surface. The amount of geothite decreases with depth and the hematite becomes more porous suggesting the goethite is a Tertiary weathering product.
