Yukon Zinc's Wolverine Mine is a high grade zinc-silver-copper-lead-gold underground mine, with on-site milling capabilities of 1,700 tonnes per day to produce zinc, copper and lead concentrates. The current mine life is ~9.5 years based on a 5.2 Mt deposit and there is potential to expand the reserve through drilling.
Yukon Zinc completed major site construction at Wolverine throughout 2009 and 2010. Mill commissioning commenced in late 2010, and production in 2012 is increasing to design capacity. The majority of the concentrate from Wolverine is trucked to the British Columbia port at Stewart.
The Wolverine Mine is located in south east Yukon, Canada, 282 km north east (as the crow flies) from the capital city Whitehorse, and 190 km by road north of Watson Lake and 180 km south of Ross River via the Robert Campbell Highway. The Wolverine property encompasses 107 square kilometres, and is accessible either via a 26 km access road west from the Robert Campbell Highway or a 1,340 metre long all- season gravel airstrip.
The Wolverine deposit, discovered in 1995, is a classic volcanogenic massive sulphide (VMS) deposit hosted in felsic volcanic and argillaceous sedimentary rocks of probable mid-Paleozoic age. The massive sulphides occur in two tabular semi-continuous lenses of moderately dipping massive sulphide mineralization within Devono-Mississippian rhyolite and argillite strata. Each of the lenses has a core zone that ranges from 6 to 25 metres in true thickness, flanked by thinner massive sulphide mineralization.
Yukon Zinc is fully permitted to operate the Wolverine Mine. Yukon Zinc was issued a Quartz Mining License by the Yukon Government in December 2006 and a Type A Water Licence by the Yukon Water Board in October 2007. Through all phases of permitting, consultation with various Federal and Yukon government agencies, the Kaska First Nation including Ross River Dena Council and Liard First Nation, and other stakeholders was conducted.
