MANITOBA – The Redpath Group of North Bay, ON, has been awarded the sinking contract for the ventilation shaft at HudBay’s Lalor gold-zinc mine near Snow Lake. Completion is expected by April 2012.
The shaft will be 857 metres long and 6.2 metres in diameter, excavated by the full face blind sinking method using two one-boom jumbos.
