The drill pattern was established to test the continuity of iron formations over a wide area centred on Mt. Asonga. The drill hole spacing varies from approximately 750m to 3,000m over a strike length of ~4.5 km and approximately 600m across strike. The four holes reported on were drilled vertically.
Kumba Iron Ore at Sishen, near Kathu, is a typical example. Owned by Anglo American, Africa's largest iron ore producer and the tenth largest in the world, Kumba operates a massive, single-pit, open cast mine that stretches 13 km north to south, and 2.5 km across at its widest point. As the mine deepens, the width is expected to reach 5 km.
We have hands-on experience with all types of ore bodies and mineralogy. Our work covers the entire iron-ore value chain, from mining through to crushing, grinding, and beneficiation by gravity, magnetic, or heavy media separation. Next comes flotation and filtering, followed by downstream processing, such as pelletizing and sintering.
