       Talvivaara cancels temporary lay-offs in order to re-start mining

Talvivaara  Mining Company  Plc ("Talvivaara"  or the  "Company") terminates the
temporary  lay-offs it started  in February 2013 in  order to re-start currently
suspended  mining and materials handling operations during May 2013. The Company
will  commence mining at the Northern end  of the Kuusilampi open pit, where the
water  level has declined such that preparations  for the re-start of mining and
crushing  operations can commence. The open pit  will continue to serve as water
management  safety  capacity  despite  the  commencement of preparations for re-
starting mine production.

The  re-start of ore  production approximately 1.5 months  in advance of earlier
plans  improves the  overall water  balance of  the mine,  as new  ore absorbs a
significant  amount of water, approximately 10-15% of  ore mass, at the stacking
phase.  For example,  ten million  tonnes of  new ore  ties up approximately one
million  cubic metres of water.  Adding new ore to  the leaching process earlier
than  anticipated  also  supports  the  achievement  of the Company's production
targets and the progress of ramp-up in accordance with plans.

The  cancellation of the temporary lay-offs  impacts 184 employees. Over half of
the planned lay-offs have been carried out since February, as approximately 121
employees were temporarily laid off during February - April.

Talvivaara Mining Company is an internationally significant base metals producer
with  its  primary  focus  on  nickel  and  zinc  using  a  technology  known as
bioheapleaching  to extract metals out  of ore. Bioheapleaching makes extraction

comprise  one of the largest known sulphide  nickel resources in Europe. The ore
body  is  estimated  to  support  anticipated  production  for  several decades.
Talvivaara has secured a 10-year off-take agreement for 100 per cent of its main
output  of nickel and cobalt to Norilsk Nickel and entered into a long-term zinc
streaming  agreement with Nyrstar  NV. Talvivaara is  listed on the London Stock
Exchange  Main Market and NASDAQ OMX  Helsinki. Further information can be found
