    of 230 employees for up to 90 days to start on 17 January


Production guidance

The  achieved full year  2012 nickel production of  12,916t was in line with the
Company's  most  recent  guidance  of  approximately  13,000t, as updated on 28
November 2012 following the gypsum pond leakage.

Talvivaara  intends to announce its  production guidance for 2013 on 14 February
2013 in  conjunction  with  its  FY  2012 results.  In the meantime, the Company
continues  to evaluate the impact  of the key drivers  for the production level,
including the near term development in the water balance, the timing of re-start
of ore production and the effectiveness of the bioheapleaching process following
the  measures being  taken to  reverse the  recent effects  of excess  water and
insufficient  aeration. Talvivaara  continues to  believe that  the greater than
50,000t of nickel currently in the heaps will provide a sufficient inventory for
a  reasonable  increase  in  metals  production  in  2013 despite  the temporary
suspension  of ore production, in effect since September 2012 and anticipated to
continue through June 2013.

Production update

Metals recovery

Talvivaara's  metals recovery plant was  temporarily suspended between 4 and 21
November  2012 as a precautionary measure due  to the gypsum pond leakage. Since
the  successful re-start on  21 November, plant performance  has in general been
satisfactory.  However, some short  term disturbances in  the automation systems
impacted  production in December and are  being investigated to avoid future re-
occurrence.

Solution  flow rates at the plant  varied from around 900 m(3)/h to 1,400 m(3)/h
in  December and have  reached 1,500 m(3)/h in  early January. Ramp-up to around
1,600 m(3)/h is anticipated in the near future.

Bioheapleaching

Bioheapleaching  has continued  to suffer  from the  excess water in circulation
that has affected the process since the spring of 2012. The water balance issues
were  further aggravated in November  by the gypsum pond  leak, which forced the
Company  to pump additional excess  water into the heap  circulation in order to
minimize  the environmental effects of  the leak. As a  result, nickel grades in
solution  pumped to metals recovery continued to decline in December and reached
a  level of around 1.3 g/l at year-end, down from around 2.0 g/l in early 2012.
In  January 2013, a positive trend in solution grades has again emerged, but the
Company estimates it will take some months before substantial improvement in the
grades can be expected. Nickel grades in solution well in excess of 3.0 g/l have
already  been previously reached, and the Company believes that such grades will
again be achievable in the longer term.

Measures  to  improve  the  leaching  performance  are  being taken based on the
findings  from extensive operational bioheapleaching  studies carried out during
the  autumn of 2012. Multiple  changes are being  implemented to ensure constant
and  balanced  distribution  of  air  within  the  primary heaps, and additional
aeration  into  the  secondary  heaps  is  being  introduced. Reclaiming and re-
stacking  of  the  existing  primary  heaps  also  continues  in order to enable
efficient recovery of the existing nickel inventory under leaching.

Ore production

As  previously announced, Talvivaara's  ore production has  been suspended since
September  2012 due  to  the  prevailing  water  balance  situation. The Company
anticipates  re-commencing mining of  new ore by  the end of  June 2013 once the
main  part of the Kuusilampi open pit has been de-watered. In the meantime, some
waste  mining will continue, which the Company  believes will reduce any risk of
production  problems upon re-start. Part of the  mining fleet is also being used
in reclaiming ore from the primary heaps.

Cost effects

By  year-end 2012, Talvivaara  estimates having  achieved approximately  EUR 20
million  in  operating  cost  savings  due  to  the  temporary suspension of ore
production  since  September.  Further  savings  of  at least EUR 30 million are
expected  to be  realized assuming  the suspension  of ore  production continues
through June 2013.

In the fourth quarter, the Company incurred approximately EUR 13 million in non-
recurring   costs  from  stemming  the  gypsum  pond  leak  and  minimizing  its
environmental effects.

Talvivaara considers systematic cost savings to be one of its key targets in the
near term.

Water balance management

Talvivaara's special task force on water management, Operation Otter led by Jari
Voutilainen  reporting directly to  CEO Pekka Perä,  focuses on the planning and
execution  of necessary water  storage and pumping  arrangements and waste water
neutralization measures to secure a sustainable water balance at the mine site.

At  the  metals  recovery  plant,  iron  precipitation  and final neutralization
capacities  of process  waters are  being improved  in order to further increase
recycling  of process  waters and  to ensure  that any  discharged waters are of
sufficiently  good quality.  Similarly, the  utilization of  the reverse osmosis
based  water treatment plant is being  optimized and additional capacity will be
installed  during the spring. Furthermore, Talvivaara is investing in additional
lime  slaking and milk of lime  capacity to increase its neutralization capacity
for the treatment of mine and process waters.

Following the gypsum pond leakage, Talvivaara continues to neutralize the waters
currently  stored  in  the  safety  dams  and  in  the  Kuusilampi  pit,  and is
constructing  additional neutralization  facilities at  the Southern  end of the
mine  area close to  the Kortelampi dam  as well as  close to the  open pit. The
Kortelampi  safety  dam,  which  was  initially  built  to contain the leak, was
elevated  to its  final height  during December  and early January. In addition,
several  additional dam structures both in  the Southern and Northern directions
from  the mine are planned  and will be constructed  as part of Operation Otter,
thereby  further preparing  the mine  area for  the forthcoming  spring melt and
mitigating  the risk  of environmental  impacts from  any potential  future leak
situation.

The  soil contaminated during  the leak by  neutralization precipitates is being
removed  and treated. The  approximately four hectares  of marsh area around the
Southern  edge of  the mine  concession area  that contains  the precipitates is
uninhabited and was recently acquired by Talvivaara.

In order to reach a sustainable water balance situation, Talvivaara will have to
treat  and release into the environment approximately 3.8 million m(3) of water,
out  of  which  a  substantial  proportion  is  rain and natural catchment water
accumulated  at the mine site over time. The discharge water quality is targeted
to  be  in  line  with  the  specifications applied for in Talvivaara's upcoming
environmental permit update, which is expected to be received in the spring. The
environmental  impact of the release  is anticipated to be  mainly caused by its
sulphate   content,  whereas  the  Company  expects  any  metal  burden  to  the
environment  to remain  limited. The  effects of  the sulphate  discharge on the
downstream waters will be simulated over the coming weeks.

At present Talvivaara anticipates the capital expenditure required for the water
management  improvements  to  amount  to  approximately  EUR 17 million, largely
incurred  in 2013. However,  evaluation and  planning of  the necessary measures
continues and may still have some impact on the expenditure. In the medium term,
Talvivaara continues to target a nearly closed circuit water circulation system,
reducing  the risk of  weather conditions impacting  the Company's operations or
environmental  safety. As  a result  of existing  water management capacity, the
investments  described  above  and  release  of  excess  waters currently at the
minesite, Talvivaara expects to be in a position to achieve this target.

Environmental update following the gypsum pond leakage

As  in November, shortly after the gypsum pond leakage, only local environmental
impact within the immediate vicinity of the mine area has been detected to date.
The  Company and authorities continue to monitor  the situation and expect to be
able to determine the eventual impact of the leak during the coming summer.

Management changes

Talvivaara  will re-organize its management, effective as of 16 January 2013, as
follows:

  * Pertti Pekkala, formerly General Manager, Research and Development, is
    appointed
    Chief Production Officer (Metals Recovery)
  * Kari Vyhtinen, formerly Chief Investment Officer, is appointed Chief Mining
    Officer
  * Mikko Korteniemi, formerly Chief Production Officer (Metals Recovery), is
    appointed Chief Maintenance Officer with responsibility for maintenance,
    procurement and warehousing
  * Jari Voutilainen, formerly Chief Mining Officer, is appointed General
    Manager,
    Water Management with full-time responsibility for water management


All  four appointees are members of the Executive Committee, with Pertti Pekkala
a  new addition to it.  Pertti Pekkala, Kari Vyhtinen  and Mikko Korteniemi will
report to COO Harri Natunen, and Jari Voutilainen will report to CEO Pekka Perä.

With  the re-organisation and formation of a central maintenance unit comprising
procurement,  warehousing  and  all  maintenance  activities, Talvivaara aims to
optimize  its  maintenance  operations  and  increasingly  focus  on  preventive
maintenance for increased operational and cost efficiency.

Co-operation consultations for temporary lay-offs

To support the Company's cost savings initiatives and overall efficiency, and to
adjust  the  level  of  personnel  to  the temporarily suspended ore production,
Talvivaara  is considering  temporary lay-offs.  The Company  estimates that the
maximum  number  of  employees  impacted  is  230 and that the estimated maximum
duration of the lay-offs would be 90 days between 18 February and 30 June 2013.
All  three corporate entities: Talvivaara Mining Company Plc, Talvivaara Sotkamo
Ltd  and Talvivaara Exploration  Ltd are within  the scope of the consultations.
Talvivaara has invited employee representatives to co-operation consultations in
accordance with the applicable law.

Financing

As previously announced in connection with the Company's Q3 2012 interim report,
Talvivaara is undertaking an assessment of a range of funding options, including
debt,  convertible bonds,  royalty streams  and equity,  in order  to secure its
financial flexibility and a sufficient level of liquidity.


Pekka  Perä,  CEO  of  Talvivaara,  commented:  "Our  team  has  mobilized  very
effectively  and has worked extremely hard to  mitigate the impact of the gypsum
pond leak on our operations and the environment as much as possible. Some of the
results  of  this  hard  work  are  beginning  to  show  in  the  stability  and
availability of the metals plant, which has been operating to encouraging levels
over  the past few weeks. We are putting a lot effort on the comprehensive water
balance management measures and enhancing bioheapleaching performance. This work
has  progressed well,  but it  will take  some time  for the full benefits to be
realized.

Challenges  remain over  the next  few months.  Due to  the water balance we may
temporarily  have to lay off a number  of our employees whilst mining activities
remain  suspended during the first half of  the year. Every effort is being made
to provide full support to all our employees and minimize the negative impact of
these  potential measures.  To achieve  this, we  are working  very closely with
employee  representatives as  part of  a comprehensive  consultation process. We
have  every confidence that the measures we are taking to preserve the long term
financial stability of the Company will be of short duration and that we will be
able  to return to a  sustainable ramp-up path towards  full capacity during the
second half of this year."
