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.
