The Wolf mineral claims are located in the Pelly Mountains southwest of the Tintina Trench, approximately 40 km west of the Kudz Ze Kayah claim block. The property is located at the south-eastern end of the Pelly Mountains volcanic belt, an arcuate belt of rocks of Late Devonian to Early Mississippian age, measuring about 80 km long and up to 25 km wide, that forms part of the Pelly-Cassiar Platform. During the 1970’s several volcanic massive sulphide (VMS) deposits were discovered at the north-western end of the belt.
The property, comprising 18 mineral claims and covering 372 Ha, has been explored by a variety of companies since the 1950s. The property encompasses the Wolf polymetallic (Zn-Pb-Ag) volcanogenic massive sulphide (“VMS”) deposit, discovered by Atna Resources in 1996 and drilled over several seasons until 1998, after which exploration activity ceased. Significant drill results from this phase of work include:
The historic drill intercepts delineate a higher grade ‘keel’ of Zn-Pb-Ag-rich massive sulphide that has a strike extent of ~125 m, a down-dip extent of ~400 m, and an average thickness of ~12 m. It is likely that stratigraphy hosting the Wolf deposit may be overturned, as stringer-style mineralisation occurs above the massive sulphide deposit and an extensive barite-carbonate exhalite unit occurs below it. Drilling to date indicates that the Wolf deposit remains open along strike and down-dip.
Additional Zn-Pb-Ag-rich sulphide mineralisation has been identified ~1.2 km to the east of the Wolf deposit, at the East Slope Zone. Drilling in 1998 intersected massive and semi-massive sulphides with grades of up to 5.7% Zn, 2.1% Pb and 43g/t Ag over 4.6 m true width (WF98-45). Additional drilling is required to test the extent of mineralisation at East Slope Zone.
In January 2017 BMC announced a Mineral Resource estimate (JORC 2012) for the Wolf deposit comprising 3.0 Mt @ 4.9% Zn, 1.4% Pb, 42g/t Ag (Inferred) using a modelled 2% zinc cut-off grade. Mineralisation at both the Wolf and East Slope Zone prospects remains open at depth, and further drilling is warranted to test the potential for additional base and precious metal-rich mineralisation.
