History

Birchtree mine originally opened in 1965 until 1978 when it was put in "standby" until 1988. The mine reopened again in 1989. In 2000 Inco authorized US$48 million to deepen the mine to 4,100 feet (1,250 m), expanding production to 3,800 tons per day. The Deepening Project allowed Inco to access ore between the 3950 level and 2300 level. In 2002 Birchtree Mine started producing ore from between 2750 level and 2300 level. In 2003 the first ore was extracted between 3950 level and 3450 level.

Safety

In 2005 Birchtree mine was the recipient of the John T. Ryan Trophy for having achieving the lowest accident frequency of all Canadian metal mines. In 2008 it received the regional John T. Ryan trophy for the Prairies & Northwest Territories.
