REGULATORY RELEASE

23 May 2013

Further update on union recognition discussions

Lonmin Plc ("the Company") announces that no resolution was reached today in further negotiations with the Association of Mineworkers and Construction Union (AMCU) in ongoing attempts to conclude a new recognition agreement.

The meeting, conducted under the auspices of the Commission for Conciliation, Mediation and Arbitration (CCMA), was a final attempt by the parties to resolve the dispute before commencing the arbitration process.

Lonmin has referred the matter for arbitration. This means that both parties will present their respective views to the arbitrator who will then make a ruling which will be binding on both Lonmin and AMCU. This is part of the dispute resolution process provided for by the Labour Relations Act. There is no set timeframe to conclude this process but it is reasonably expected that it should take approximately four to six weeks to complete the arbitration process.

"We are disappointed that we have been unable to find common ground but remain hopeful that the dispute will be resolved, which is in all of our interests," said Acting CEO Simon Scott.

Lonmin has presented a recognition agreement that it believes to be in the best interests of all stakeholders, while at the same time according the same rights and privileges enjoyed by the previous majority union to AMCU.

"In the spirit of the Peace Accord signed by all parties, we urge everyone to allow the process to take its course peacefully and without incident" added Mr Scott.

The Company will update the market further when appropriate.

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.
