Exploration History

1950: Chellow Gold Mines Ltd. Conducted geological mapping, trenching and diamond drilling in the Lower McVicar Lake area. 1959-1961: Kenlew Mines Ltd conducted geological mapping, stripping, trenching and diamond drilling in the lower McVicar Lake area and the area to the east of McVicar Lake. 1968-1969 New Jersey Zinc Exploration Company (Canada) Limited conducted geological mapping, geophysics, trenching and limited diamond drilling for VMS mineralization in the area north of north of McVicar Lake. 1971 Hoey Syndicate conducted geological mapping, trenching and geophysics for Cu-Ni-PGE mineralization in the lower half of the McVicar Lake area. 1977-1981, 1987, 1991 Cominco Ltd conducted extensive airborne geophysical surveys as well as diamond drilling over the McVicar Lake and Andy lake areas, well as limited diamond drilling in McVicar and Cannon Lake areas for gold and base metals. 1985-1994 Utah Mines, later BHP-Utah Mines, and then simply BHP conducted extensive grid mapping, geophysics and diamond drilling on the area surrounding McVicar Lake resulting in the discovery of the Altered Zone and Lower McVicar Lake structural zones and several associated gold showings. Utah Mines also conducted extensive work in the western Lang Lake area. 2001-2003 Prospector Consolidated Inc and Continuum Resources Ltd, conducted extensive trenching and limited diamond drilling for gold on the old BHP-Utah Mines property in the McVicar Lake area.

Mineralization Comments

Mar 29, 2007 (Mark Puumala) - Janes, Seim and Storey (1991) indicate that this occurrence is located within a 3 to 5 m wide mineralized shear zone in mafic metavolcanics. The shear zone occurs at the contact between mafic metavolcanics and greywacke (Bonner 1992). The mineralized shear zone is reported by Janes, Seim and Storey (1991) to have an orientation of 090/86. The metasediment/metavolcanic contact zone is reported by Bonner (1992) to be silicified, while the central portion is fissile chloritic schist that contains narrow lenses of grey to white quartz (Janes, Seim and Storey 1991). Mineralization is reported by Janes, Seim and Storey (1991) to consist of pyrite stringers parallel to foliation planes, with an average concentration of approximately 3%. Sampling of this occurrence by Belore Mines is reported to have returned assays of up to 0.45% Cu, while a 1990 OGS sample is reported to have returned an assay of 14,126 ppb Au (Janes, Seim and Storey 1991). Subsequent surface sampling and diamond drilling by BHP Minerals did not produce any significant assay results (Waldie 1993).
