Update on NUM Court Application and Union Recognition 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 Update on NUM Court Application and Union Recognition Lonmin Plc ("the Company") would like to update the market, further to our regulatory release of 8 July 2013, on a court case which concluded in South Africa today involving issues around union recognition. The National Union of Mineworkers (NUM) applied to the labour court to suspend the 90 day notice period for the derecognition of NUM as the largest union at Lonmin. Giving judgment this morning, the judge dismissed NUM’s case, struck the matter off the roll and awarded costs against the union. This conclusion allows the present timetable around recognition, as well as the ongoing arbitration procedure the Company is involved in with AMCU, to continue unchanged. As previously announced, the recognition agreement between the NUM and Lonmin will expire on 16 July 2013, whilst the arbitration proceedings with AMCU are still scheduled for 29 July 2013. Lonmin remains wholly committed to finding a sustainable solution to the issue of union recognition which is fair and equitable and with which all stakeholders can agree. It also believes that employees have the right to be represented by the union of their choice. The Company will update the market further when appropriate. 15 July 2013 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 Anthony Cardew / James Clark +44 20 7930 0777 Sue Vey +27 72 644 9777 Brunswick – Johannesburg Itumeleng Mahabane / +27 11 502 7400 / Tim Schultz +27 82 309 2496 Sponsor: J.P.
