LONMIN PLC

SUCCESSFUL COMPLETION OF RIGHTS ISSUE AND PLACING OF RUMP

On 11 December 2012, Lonmin Plc ("Lonmin" or "the Company") announced that, as at 11.00 a.m. (UK time) on 10 December 2012, being the latest time and date for receipt of valid acceptances, it had received valid acceptances in respect of 354,416,422 New Shares, representing approximately 96.97 per cent of the total number of New Shares offered to Shareholders, pursuant to the Rights Issue announced by the Company on 9 November 2012.

Lonmin confirms that Citigroup Global Markets Limited, HSBC Bank plc, J.P. Morgan Securities plc and Standard Bank Plc have procured acquirers for the 11,080,521 New Shares for which valid acceptances were not received at a price of 272 pence per share, equivalent to ZAR 38.0025 per share at the time of sale.

Accordingly, none of Citigroup Global Markets Limited, HSBC Bank plc, J.P. Morgan Securities plc, Standard Bank Plc or the other Underwriters, as underwriters pursuant to the Underwriting Agreement, will be required to subscribe for any New Shares under the terms of the Underwriting Agreement.

The net proceeds from the sale of these New Shares, after deduction of the UK Issue Price of 140 pence (or its equivalent in ZAR at the time of sale, as the case may be) per New Share and the related expenses of procuring subscribers (including any applicable brokerage and other commissions and any amounts attributable to VAT and currency conversion costs), will be paid to those Qualifying Shareholders whose rights have lapsed in accordance with the terms of the Rights Issue, pro rata to their lapsed provisional allotments, save that, in accordance with the terms of the Rights Issue, individual amounts of less than GBP 5.00 (or the equivalent in ZAR, calculated using the foreign exchange rate at the date of payment but which would have been approximately ZAR69.67 based on the spot exchange rate at the close of business on 10 December 2012) will not be so paid but will be retained for the Company's own benefit.

Capitalised terms used and not defined in this announcement shall have the same meanings as in Part XIV (Definitions and Glossary) of the prospectus relating to the Rights Issue dated 9 November 2012.

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.
