from their report:

"Total cash costs for the fourth quarter of 2012 were $769 per ounce versus $671 per ounce for fourth quarter 2011. The increase in total cash costs per ounce in the fourth quarter of 2012 is mainly due to higher costs at LaRonde, Meadowbank and the temporary suspension of operations at Creston Mascota. "

BUT, on an annual basis, costs were actually less than guidance (640 vs 660/ounce guidance);  just really worried how the costs are creeping up in the 4th quarter!
