Production update

Stock Exchange Release

Talvivaara Mining Company Plc

7 April 2011





      New production record slightly short of guidance achieved in Q1 2011

     Production guidance for 2011 reduced to 22,000-28,000 tonnes of nickel
                        due to necessary plant upgrades



Talvivaara  Mining Company Plc ("Talvivaara" or the "Company") announces that it
has  achieved a new  quarterly production record  of 4,215t of nickel during the
period  of  January-March  2011. Although  production  was  marginally below the
Company's  guidance, it exceeded the previous quarter's nickel output by 10% and
confirmed further progress in production ramp-up at the Sotkamo mine.

The  new quarterly production record was  achieved despite a series of technical
issues  resulting in low availability of the metals recovery plant. Particularly
good  production levels were achieved in  March, when the nickel output averaged
an annualised rate of over 32,000t for the last ten days of the month, achieving
also new monthly and weekly records.

Despite the recent success in metals recovery, the Company believes that certain
upgrades  and modifications at the  plant are necessary in  order to sustain the
achieved  throughput rates  and to  ramp up  production further. The Company has
therefore  decided to  bring the  annual maintenance  break forward to April-May
2011 and  to extend  this scheduled  break to  allow for  all of  the identified
issues  to be addressed and for the plant  to be thoroughly inspected as part of
the   Company's  preventive  maintenance  plan.  The  overall  duration  of  the
modification programme is to be extended by a fortnight.

The  Company anticipates scheduling a  second maintenance stoppage for September
or  October in order to install long  lead-time equipment which is not available
during  the first stoppage, and to further enhance parts of process equipment in
order  to avoid potential problems caused  by exceptional winter conditions. The
second  maintenance programme  is estimated  to last  approximately one week and
will complete the upgrading of the plant for sustainable full scale production.

The  planned  plant  modifications  and  maintenance works involve increasing of
sulphur  melting  and  certain  pumping  capacities,  cleaning  and upgrading of
hydrogen  sulphide  generators,  inspection  and  maintenance  of  reactors  and
thickeners,  and numerous small modification items, e.g. doubling up of selected
process  pipelines,  that  help  improve  production reliability and sustainable
capacity.  No major equipment  additions or replacements  are anticipated; hence
the  upgrading and maintenance programmes are  not expected to materially affect
the Company's capital expenditure during the year.

The  impact on  production output  of the  planned modification  and maintenance
programmes depends on the timing and eventual length of the production stoppages
and  the resulting improvement in production reliability and capacity. Delays in
reclaiming  the  primary  heap  may  also  have  an  impact on production due to
corresponding  delays in  obtaining leach  solution from  the secondary  heap to
metals recovery.

Overall,  the Company believes it realistic to anticipate a production shortfall
of  5,000-8,000t of nickel  from the  previous guidance. Accordingly, Talvivaara
revises its production guidance for 2011 to 22,000-28,000t of nickel.

Pekka Perä, Talvivaara's CEO commented: "Whilst the maintenance and upgrade work
at  our metals plant will have a short-term impact on our production targets, it
will  put  Talvivaara  in  a  stronger  position  in  the  long term. During the
programme  we  will  concentrate  on  both  preventive maintenance, which should
minimise  unforeseen production  problems in  the future,  and on upgrades which
will  boost production  capacity and  reliability and  improve resilience during
difficult weather conditions."
