The potential for VMS copper-lead-zinc silver-gold deposits associated with mid-Paleozoic volcanic rocks of Yukon-Tanana Terrane in the Finlayson Lake district was first recognized with the discovery of the Kudz Ze Kayah deposit in 1994 (11.3 million tonnes of 5.9 percent zinc, 1.5 percent lead, 0.9 percent copper, 1.37 grams/tonne silver, 1.3 grams/tonne gold). Since then, the Wolverine (3.75 million tonnes of 12.5 per cent zinc, 1.4 percent lead, 1.4 percent copper, 336.6 grams/tonne silver, 1.6 grams/tonne gold) and other deposits have been discovered. These include Ice (4.5 million tonnes of 1.48 percent copper), Fyre Lake (8.2 million tonnes of 2.1 percent copper, 0.11 percent cobalt, 0.73 grams/ tonne gold) and GP4F (1.5 million tonnes of 6.4 percent zinc, 3.10 percent lead, 0.10 per cent copper, 90 grams/tonne silver and 2.0 grams/tonne gold). Recent geological mapping in this district by the Yukon Geological Survey has shown that there are at least four discrete packages of felsic and mafic volcanic rocks with the potential to host VMS deposits. The Wolverine deposit is now in the final stages of permitting and development could begin in the fall of 2007.
