Talvivaara Mining Company Plc.
18 March 2010
A leakage in the gypsum pond was detected today at the Talvivaara mine. The
leakage did not cause discharge outside the mining concession. Talvivaara
strives to minimise any damage or impact on the environment and has taken all
necessary precautions and actions to rectify the situation.
In order to decrease the inflows into the gypsum pond the Company shut down the
metals recovery plant temporarily and started securing the settling basin
system around the gypsum pond. The cause of the leakage is being investigated
and the monitoring of water samples has been intensified as a precautionary
measure.
