                          of the metals recovery plant 
 
Talvivaara Mining Company Plc ("Talvivaara" or the "Company") announces that the 
leakage  of the  gypsum pond at the Sotkamo  mine has stopped. Most of the water 
that  had  previously  leaked  from  the  pond  is  contained  within the mining 
concession  area by the newly built fourth safety dam. No further release of the 
leakage water outside the mine area is anticipated. 
 
Before  the fourth safety dam was completed, some water from the gypsum pond had 
to  be released towards South between Thursday 8 November and Sunday 11 November 
2012. The  released  water  was  neutralized  with  lime  in order to reduce its 
acidity  and  to  precipitate  its  metal  content.  However, the effects of the 
discharge  can  be  seen  in  the  nearby  waters as temporarily increased metal 
concentrations.   According   to   the   statement  by  Finland's  environmental 
administration  on 13 November 2012, the samples taken  from water bodies on the 
Southern  side of  the mine  area on  11 November 2012 show metal concentrations 
that  are harmful to  life forms in  these waters. Metals  concentrations in the 
downstream  river have  already clearly  reduced following  the stoppage  of any 
leakage  outside the  mine area.  The Environmental  administration continues to 
simulate  the effects  of the  discharge as  analytical data  from water samples 
accumulates and informs of any effects in downstream waters. 
 
Talvivaara  has  on  13 November  2012 given  the clarification requested by the 
Kainuu  Centre for Economic Development,  Transport and the Environment ("Kainuu 
ELY  Centre")  in  order  to  grant  permission for the re-start of Talvivaara's 
metals  recovery plant. After reviewing the clarification, the Kainuu ELY Centre 
has  requested certain further clarifications,  which the Company anticipates to 
provide during 14 November 2012. 
 
Talvivaara  has  stated  in  its  Production  Update  of 15 October 2012 and its 
Interim  Results  of  8 November  2012 that  it  anticipates  its fourth quarter 
production  to increase  over the  4,030 tonnes of  nickel achieved in the third 
quarter. As the stoppage of the metals recovery plant continues, the Company has 
to  re-assess this  target, but  can only  do so  after it  has received the ELY 
Centre's decision on the permitted start-up date of the metals recovery plant.
