Regulatory Release: Incident at Number Two Furnace Lonmin Plc (Incorporated in England and Wales) (Registered in the Republic of South Africa under registration number 1969/000015/10) JSE code: LON Issuer Code: LOLMI & ISIN : GB0031192486 ("Lonmin") REGULATORY RELEASE 30 April 2013 Incident at Number Two Furnace Lonmin Plc (Lonmin) announces that it has experienced an incident at its Number Two furnace, which has resulted in the furnace being shut down. No one was injured. The incident has happened at a time when Lonmin had just shut down the Number One furnace for its planned upgrade of the hearth and shell. Our initial estimate is that a full repair to the Number Two furnace will take 30-40 days. A full inspection will be conducted once the furnace has cooled down later this week. The Three Pyromet furnaces, which have around 50% of our capacity requirements, continue to operate. In the meantime, we will be assessing the options around Number One and the impact of Number Two and we will update the market in due course. In addition, following the fatality at the Merensky section of the K3 shaft last week, drilling and blasting operations at K3 have been suspended until the investigation, which is being undertaken in partnership with all stakeholders, is complete. - ENDS – ENQUIRIES Investors / Analysts: Lonmin Tanya Chikanza (Head of Investor Relations) +27 11 218 8358 / +44 20 7201 6007 Ruli Diseko (Investor Relations Manager) +27 11 218 8300 Media: Cardew Group James Clark / Alexandra Stoneham +44 20 7930 0777 Sue Vey +27 72 644 9777 Brunswick - Johannesburg Cecilia de Almeida +27 11 502 7400 / +27 83 325 9169 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.
