Runoff curtails Kidd production

Faced with an influx of runoff water from the surface, the Kidd mining division of Falconbridge (FL-T) has shut down operations below the 2,800-ft.

level of the mine complex near Timmins, Ont.

The shutdown affects Kidd’s No. 2 and No. 3 mines, which together account for half the division’s production. The No. 1 mine, which produces the other half, will remain in operation.

A rock wedge broke away from the east wall of the mined-out open pit last November, allowing surface water to flow into the mine at an unusually high rate. The concern is that additional water in the mine workings may mix with underground muck and allow the muck to flow into active areas.

Just over 100 employees are affected by the shutdown; they will receive vacation pay during the period work is stopped. The No. 2 mine is expected to be back in operation by April 13 and No. 3 by April 18.
