An alarm system that could have warned three workers about dangerous water levels was disconnected when they drowned at a Quebec mine, last October 30, 2009. The company, Metanor Resources Ltd., sent the three miners down the shaft in an elevator at the Bachelor Lake gold mine in Desmaraisville, Quebec. They were there to help rehabilitate a mine shaft. The miners entered the cage on the six level and headed toward the 12th but encountered water about halfway through the 10th level. The elevator operator grew concerned when the workers did not signal that they reached their destination.

It took rescue workers three days to recover the miners, whose bodies were frozen in blocks of ice.
