Yukon has an extraordinary endowment of tungsten mineralization. Almost 900 million tonnes of contained metal have been estimated for the territory. The majority of Yukon tungsten occurrences are skarns developed in Selwyn basin Cambrian limestone near contacts with mid-Cretaceous plutons. Other occurrence types include veins and porphyries. Mactung, located near MacMillan Pass close to the Northwest Territories border, is a scheelite skarn and is one of the world’s largest high-grade tungsten deposits. The Cantung scheelite skarn deposit in the Northwest Territories close to the Yukon border was a major world tungsten producer, producing 85% of Canadian tungsten from 1952-1986.
The most significant tungsten porphyry occurrence in Yukon is Northern Dancer (formerly known as Logtung). It is a low-grade, high-tonnage stockwork deposit with associated molybdenum.
