Cantung Mine is a tungsten producer in the Nahanni area of the Northwest Territories, Canada, located northeast of Watson Lake in the Flat River Valley of the Selwyn Range close to the Yukon border. Tungsten was originally discovered in the area in 1954 by prospectors. Cantung Mine operated from 1962 to 1986, again from 2002 to 2003, and most recently reopened in 2005. Production was suspended October 2009 and the company plans to resume production October 2010.
After a re-finance, the mine reopened September 1, 2005. By November 2007, North American Tungsten stated that Cantung had approximately two years of tungsten reserves left, but, combined with its Mactung operation, the two hold 15% of the World's known tungsten.
