LOCATION
The Cantung Mine is located in the Nahanni area of western Northwest Territories, Canada, approximately 300 km by road northeast of Watson Lake, Yukon, close to the Yukon border. The mine is a primary producer of tungsten concentrate from open pit and underground mines. It was opened in 1962.
HISTORY
Prospectors discovered the Cantung Mine tungsten deposit in 1954, while looking for copper. In 1959, the Canada Tungsten Mining Corporation Ltd. was formed to acquire and develop the property. The Cantung Mine commenced production in 1962 from an open pit at the rate of 300 tons per day (stpd), with suspensions in 1963 due to low tungsten prices and in 1966 due to the destruction of the mill by fire. The construction of a new 350 stpd mill was completed in 1967 and, in 1969, the capacity was increased to 450 stpd.
In 1971, drilling discovered the "E Zone". This zone was accessed through an adit collared at the valley bottom, close to the town site. The mill began to process the underground ore in 1974. In 1975, the mill was further expanded to 500 stpd. A major mill expansion in 1979 increased the mill capacity to 1,000 stpd.
In 1985, Amax Inc consolidated ownership of the Cantung Mine and transferred all tungsten assets, including the Mactung Project at Macmillan Pass, to Canada Tungsten Mining Corporation, retaining majority control. Aur Resources Inc. (Aur) purchased Amax Inc's controlling interest in 1995 and Canada Tungsten and Aur merged in 1996.
In 1997, North American Tungsten Corporation Ltd. ("NATCL") purchased the Cantung mine, together with the related tungsten assets of the former Canada Tungsten Inc., from Aur.
After an improvement in tungsten prices commencing in 2000, NATCL reopened the Cantung mine in December 2001. Underground production and milling resumed at this time. In December 2003, NATCL was placed under the protection of the Companies Creditors Arrangement Act (CCAA), and the mine was closed. In November 2004, NATCL successfully completed a plan of arrangement to deal with creditors, allowing planning for reopening to commence. Preparatory work for the reopening began in July 2005, and production resumed in late September 2005.
The Cantung mine suspended operations in October 2009 and resumed production in October 2010.
