Talvivaara Invests More than EUR 13 Million in Environmental Technology


Highlights

* New technologies to improve the quality of effluent waters, reduce odour
emissions into surrounding areas and limit dust emissions
* The investments include reverse osmosis technology to improve the quality of
effluent waters and a catalytic burning unit to treat hydrogen sulphide
odour-generating gases
* Talvivaara is also building a water recycling system and drilled wells to
 reduce water intake from nearby lakes
* Dust emissions will be reduced by a new dust removal system at the materials
handling screening hall


Talvivaara Mining Company Plc ("Talvivaara" or the "Company") has signed a
contract with the Dutch company Lenntech BV for delivery of a reverse osmosis-
based water treatment system. The facility will cost EUR 4 million and it will
be commissioned by the end of November 2012. The system consists of two
production lines, each with a purified effluent output of 70 m(3)/h, and an
additional contractual option for a third line. The choice of technology and
scaling of the facility followed the promising results of pilot testing
conducted with Teollisuuden Vesi Oy.

Talvivaara has also entered into a contract with the Finnish technology company
Formia Emissions Control Oy for the delivery of a catalytic burning unit,
primarily designed to eliminate odour emissions. The unit will cost EUR 4
million and it will be commissioned by the end of 2012. The investment is part
of Talvivaara's own target to reduce odour emissions at and around the minesite.
Effectiveness of the technology has been verified with a pilot plant. In
addition to reducing emissions and odours, the commissioning of the Formia Smart
burning unit will enable Talvivaara to reduce the consumption of chemicals
currently used in the process in an energy-efficient manner.

Permit limits for emissions proposed by the Company achievable ahead of schedule

In addition to the investments detailed above, over the past year Talvivaara has
increased the recycling of process waters within the minesite and initiated
construction of drilled wells at the open pit mine. The drilled wells reduce the
need for water intake from surrounding lakes. The drilled well-system and water
recycling will reach full scale and scope by the end of May 2012. The cost of
these investments totals EUR 3.1 million.

As a result of the measures taken in 2011-2012, Talvivaara has already
significantly reduced the sulphate and manganese content in effluent waters. The
new water treatment investments will further considerably reduce the levels of
sodium, sulphate and manganese in effluent waters by the end of 2012. The lower
permit limits proposed by the Company for 2015 will hence be achievable already
in early 2013. Further development measures to improve the water balance of the
mine will also continue following the investments announced today.

Reduced dust emissions from materials handling

Additionally, in June 2012 Talvivaara will initiate the implementation of a new
dust removal system in the materials handling screening hall, following which
screening hall dust emissions will decline to below 10 mg/m(3) during 2012. The
cost of the investment will be EUR 2 million.

All of these initiated and partially already completed investments are part
Talvivaara's environmental improvement strategy announced in January 2012. More
information on the Company's sustainability targets and improvement measures are
detailed in Talvivaara's 2011 Annual Report, corporate website and on the
Finnish language environmental website www.paikanpaalla.fi.
