Talvivaara Mining Company Plc, Crushing enhancement and ramp up of
mining
Talvivaara Mining Company  Plc ("Talvivaara" or  the "Company"),  the
Finnish mining company with  a primary focus on  nickel and zinc,  is
pleased to  announce  that its  upgraded  crushing circuit  has  been
successfully installed and commissioned.

The redesigned  crushing  circuit has  been  in operation  since  the
beginning of September,  during which period  the production  volumes
have been gradually increased. The circuit's overall production  rate
on a weekly basis is now in excess of an average of 40,000 tonnes per
day, with volumes in excess of 50,000 tonnes per day being reached on
individual days. While further  optimisation and capacity testing  of
the process remains to  be done, the  production volumes achieved  so
far indicate the  circuit to  be capable of  the targeted  production
rate of 60,000 tonnes per day, corresponding to 22 million tonnes per
annum. With ore hauling capacity limiting the throughput for the time
being, the Company is confident the targeted production volumes  will
be achievable following the  commissioning of additional ore  hauling
capacity early next year.

Talvivaara's CEO Pekka Perä commented:"I am pleased  to report  that for the  first time  in the  Company's
history, mining  and  materials handling  departments  are  operating
above budgeted tonnages. While there is  still work to be done, I  am
delighted that all the production processes are finally reaching  the
required capacities."

About Talvivaara Mining Company Plc.
Talvivaara is a  Finnish mining  company operating a  large open  pit
nickel mine  in  Sotkamo,  Finland.  Talvivaara  aims  to  become  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  of
metals  from  low  grade  ore  economically  viable.  The  Talvivaara
deposits comprise one of the largest known sulphide nickel  resources
in  Europe.  The  ore  body  is  sufficient  to  support  anticipated
production for at least  46 years. Talvivaara  has secured a  10-year
off-take agreement for 100 per cent of its main output of nickel  and
cobalt to Norilsk Nickel.  Talvivaara is listed  on the London  Stock
Exchange Main Market and Nasdaq OMX  Helsinki and is included in  the
FTSE   250   Index.   Further    information   can   be   found    at
