Notes to editors

Lonmin, which is listed on both the London Stock Exchange and the Johannesburg Stock Exchange, is
one of the world's largest primary producers of PGMs. 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
known 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.
