LONMIN PLC - Operational update

Operational update

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


31 December 2014

Operational Update


Lonmin Plc (Lonmin) announces that it has safely stopped its Number Two Furnace following the
detection of electrode breaks in the furnace which were creating an unstable and high temperature
operating environment. The stoppage, which is not expected to exceed 21 days, should allow the
integrity of the furnace conditions to be safely addressed. The three smaller Pyromets continue to
operate. The work on the Number One Furnace is progressing well and on schedule.

We expect 2015 sales to be back end loaded into the second half of the 2015 financial year and
there will be an increased build up of concentrate stocks, which we expect to unwind by year end.
We continue to explore commercial ways of mitigating the stock build up. We expect our net
borrowings to further increase at the end of March 2015 as a direct result of the lower sales volumes
in the first half, but they are expected to remain within our borrowing facilities. Our sales guidance
for 2015 financial year remains unchanged.



We will update the market when we release our 2015 Q1 Production results on Thursday 29 January
2015.

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 producing assets 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.
