These metals are essential for many industrial applications, especially catalytic converters for internal combustion engine emissions, as well as their widespread use in jewellery. Lonmin’s operations are situated in the Bushveld Complex in South Africa, where nearly 80% of global PGM resources are found. The Company creates value for shareholders through mining, refining and marketing PGMs and has a vertically integrated operational structure – from mine to market. Lonmin’s mining operations extract ore from which the Process Division produces refined PGMs for delivery to customers. Underpinning the operations is the Shared Services function which provides high quality levels of support and infrastructure across the operations.
