Xstrata Nickel’s Sudbury Operations has announced the indefinite suspension of mining operations at its Montcalm Mine in Timmins, Ontario, Canada after a geotechnical review showed structural damage to the mine. Unplanned ground movements at Montcalm forced underground activity at the mine to be stopped at the end of March 2009 to ensure the safety of the workforce and enable geotechnical investigations and monitoring to be carried out. Montcalm was expected to produce approximately 9000tns of nickel contained in concentrate this year. Its mine life was scheduled to end in mid 2011.
